The part number 49616-0715 appears in official datasheet tables and is used here to align checklist items with published test rows and drawings.
Use this companion as a practical datasheet decoding tool: each section points to the exact data fields engineers should quote on BOMs and EVAs, emphasizing safe operating margins, footprint checks, and procurement flags.
Quick Overview: 49616-0715 at a Glance
At a glance, this connector family is a 0.80–1.00 mm pitch, 5-pin USB Mini‑B style header optimized for compact, right‑angle through‑hole mounting. Key mechanical drivers are low profile and board retention; electrical drivers prioritize USB 2.0 high-speed differential pair integrity and adequate current carrying on VBUS.
Key Specifications Snapshot
| Parameter | Datasheet Specification |
|---|---|
| Interface Type | USB Mini-B (5-Pin) |
| Mounting Style | Through-hole, Right-Angle |
| Pitch Range | 0.80 mm – 1.00 mm |
| Flammability | UL94 V-0 |
Typical Applications & Why This Header is Chosen
Common use cases include handheld instruments, embedded device USB ports, and test-fixture interfaces where low profile and secure mechanical retention matter. Designers select this header when board real estate and right‑angle access are constraints and when compatibility with USB 2.0 high‑speed signaling and routine mating cycles are required.

Current Carrying Capacity (Visualization)
Contact Resistance & Dielectric Strength
Extract rated current per VBUS contact from the electrical table—note whether the datasheet gives both continuous and peak ratings. For USB 2.0 signalling, verify controlled-impedance guidance for the high-speed D+/D− pair. Typical pass/fail thresholds guide acceptable insertion loss, while insulation resistance (MΩ minimum) and dielectric strength (Vrms) are explicit test rows captured for signal integrity.
Mechanical Specifications & PCB Footprint Guidance
Dimensions & Tolerances
- • Pin pitch: 0.8mm - 1.0mm range
- • Right-angle profile height optimization
- • Recommended drill diameter for PTH
Assembly Considerations
Confirm through‑hole plating and recommended solder fillet dimensions. If the datasheet lists wave or reflow compatibility, note recommended maximum process temperatures and soak profiles. Provide mechanical support pads or retention posts on the PCB to avoid cracked solder joints.
Validation Checklist & Red Flags
Table-by-Table Validation
Checklist: confirm exact part number and variant; cross-check electrical tables for rated current; verify mechanical drawings and tolerances for footprint; capture material and plating notes.
Common Datasheet Traps
Watch for multiple current ratings or optional plating callouts without clear revision notes, ambiguous tolerance units (mm vs. inches), and missing test sample sizes.
Reliability, Testing, and Compliance
Environmental Safety
UL94 flammability class verification and operating temperature ranges. Look for humidity, thermal cycling, and salt‑spray test results in qualification tables.
Mechanical Lifetime
Datasheets list mating cycle life and solderability acceptance criteria. Use those numbers to set acceptance limits in the design verification plan.
Application Examples & Procurement Tips
Integration Pattern: Route USB differential pairs with controlled impedance and minimal vias near the connector, reference ground planes under the pair, and keep noisy power traces away from the D+/D− pair to preserve signal integrity.
Procurement: On purchase orders, verify full part number, plating and finish, packaging (tube, tape & reel), and lead time. Common failures include cold solder joints and bent pins—mitigate with incoming inspection criteria.
Key Summary
- ✓ Extract core electrical values (Current, Resistance, Insulation) for BOM traceability.
- ✓ Verify mechanical drawings and footprint tolerances against actual drill and pad specs.
- ✓ Validate environmental and mating cycle data to avoid assembly surprises.
