95501-2661 Modular Jack: Complete Spec Sheet & Ratings
In field and board-level testing, low-profile 6P6C modular jacks consistently account for more than 60% of voice-port footprints in legacy telephony and low-speed data designs. This guide breaks down the 95501-2661 modular jack specs and ratings so engineers can fast-track selection, layout, and verification.
Overview: 95501-2661 Modular Jack at a Glance
ID Key Identifiers & Product Family Variants
Point: The part number format encodes port count, contact arrangement, and orientation to simplify procurement decisions.
Evidence: Datasheet-reported parsing shows the family base (95501) with suffixes indicating plating and mechanical style; the full code 95501-2661 identifies a single-port, 6P6C right-angle low-profile through-hole jack.
Explanation: For BOM clarity, record port count (1), contact arrangement (6P6C), orientation (right-angle), profile (low), and mount (THT) as separate fields so variant swaps are explicit during sourcing.
APP Typical Applications and Use Cases
Point: This modular jack is optimized for voice and low-speed data rather than high-speed LAN.
Evidence: Intended use listed in manufacturer literature and typical electrical ratings point to Cat3/voice-level signaling and embedded comms ports.
Explanation: Common deployments include RJ11/RJ12 telephony, Cat3 punch-down replacements, embedded control-panel ports, and low-speed serial links; avoid for Gigabit Ethernet where impedance control and shielding are required.
Physical & Mechanical Specifications
Dimensions, Mounting and Footprint Tips
Point: Accurate mechanical data ensures correct PCB land patterns and assembly reliability.
Evidence: Datasheet-reported dimensions indicate a low mating face height and standard THT pin pitch near 1.02 mm for signal pins with larger anchor posts.
Explanation: Use the recommended through-hole pad pattern, keep-out area for mating clearance, and silkscreen orientation marks; verify drill sizes for signal pins and anchors against fabricator tolerances before panelization.
Materials, Plating and Mechanical Durability
Point: Contact and housing materials determine electrical reliability and soldering behavior.
Evidence: Typical constructions use phosphor bronze contacts with gold plating on the mating area and high-temp thermoplastic housings with datasheet-reported UL 94 V-0 flammability.
Explanation: Specify plating thickness (µin or µm), confirm housing resin grade, and select parts with mating cycle ratings matching lifecycle targets—commonly several thousand insertions for telecom-grade jacks.
Electrical Ratings & Performance Data
Voltage, Current and Contact Resistance
Point: Electrical limits define safe operating envelopes for deployed systems.
Evidence: Datasheet values typically list maximum current per contact (around 1.0–1.5 A), maximum voltage (commonly 125 VDC), and initial contact resistance in the single-digit milliohm range.
Signal Performance & Category Rating
Point: The jack’s signal-classification constrains its use for higher-speed networks.
Evidence: Category rating documented for voice/Cat3 implies limited bandwidth and higher crosstalk compared with Cat5e/Cat6 hardware.
Compliance, Testing & Reliability
Typical Factory Tests and Standards
- ✔ Contact Resistance & Insulation Resistance
- ✔ Dielectric Withstanding Voltage
- ✔ Temperature Cycling & Humidity Soak
- ✔ UL 94 Flammability Compliance
Interpreting Test Data for Design Margins
Derate current for elevated ambient, allocate safety margin on dielectric voltage, and define incoming acceptance ranges to avoid field failures.
Bench Ratings & Real-World Performance
Measured vs. Rated: Bench measurements commonly reveal small deviations from datasheet ideals after service cycles. Test labs report modest contact resistance increases after 1k–5k mating cycles and reduced retention force after mechanical abuse.
Failure Modes: Environmental stresses drive most connector failures. Typical failure modes include corrosion in saline atmospheres, contact wear from cycling, and solder-joint fatigue from board flex.
Selection, PCB Integration & Installation
How to Choose
Selection should map electrical, mechanical and environmental requirements to connector attributes. Require datasheet-proven mating cycles and clear footprint documentation.
Assembly Tips
Follow wave-solder checklists, inspect solder fillets and pin straightness, and add test points for in-circuit verification and serviceability.
Summary
- • Low-profile, 1-port 6P6C right-angle through-hole connector intended for Cat3/voice applications and board-level telephony ports.
- • Verify current/voltage limits, plating thickness, and flammability; run bench tests to confirm behavior over cycles.
- • PCB best practices: use recommended land pattern, respect mating-face keep-out, and provide mechanical anchors.
