MPN 39-01-3049: Technical Specs & Performance Data
Tested in standard connector benchmarks, housings in this 4-position crimp-plug class commonly support up to 13 A per circuit and 600 V—figures that determine suitability for power and control applications. This technical breakdown summarizes specs and performance data to assist engineers in design evaluation and integration.
This article covers product identifiers, electrical and mechanical deep-dives, recommended lab tests with pass/fail criteria, and comparative benchmarks for the 4-position plug housing.
Product Overview & Key Identifiers
Key Identifiers & Basic Description
MPN 39-01-3049 is a 4-position, dual-row crimp plug housing with a 4.2 mm (0.165") pitch. It is engineered for crimp-contact terminations (contacts sold separately) and functions as a compact solution for wire-to-wire or wire-to-board harnesses.
- 4 positions, dual-row configuration
- 4.2 mm (0.165") pitch
- Crimp termination; contacts not included
Variants & Procurement
Common variants include natural or polarized colors, with or without mounting ears. Always verify ordering codes and packaging quantities before procurement.
Technical Specs Deep-Dive
Electrical Ratings & Pin Details
Rated values typically support 13 A per circuit and 600 V insulation. Recommended wire gauge spans 18–24 AWG for optimal contact resistance.
Mechanical & Material Properties
Housings are molded from Polyamide (PA) with a UL 94 V-0 flammability rating. Operating temperatures range from -40°C to +105°C.
Performance Data & Lab-Test Interpretation
Electrical Performance Tests
Key metrics focus on contact resistance (≤10 mΩ initial) and temperature rise (<30°C above ambient at rated current). No flashover should occur during Hipot testing.
- Continuous current temperature-rise test
- Contact resistance vs. current cycling
- Dielectric withstanding voltage (Hipot)
Environmental & Reliability
Acceptance criteria require no loss of continuity after stress tests. Delta R (ΔR) should remain under 20% after thermal or mechanical fatigue.
- Thermal cycling & Humidity soak
- Salt spray for corrosion resistance
- Vibration and mating cycle endurance
Comparative Benchmarks
| Specification | Typical Alternatives | 39-01-3049 Class |
|---|---|---|
| Current Rating | 8–13 A | 13 A |
| Voltage Rating | 250–600 V | 600 V |
| Pitch | 3.96–4.2 mm | 4.2 mm |
| Material / Flammability | PA / V-0 | PA / V-0 |
* This housing stands out in the 600 V-class insulation potential combined with compact dual-row packaging, ideal for medium-power runs where space is at a premium.
Implementation Checklist & Design Integration
Verification Steps
- Confirm exact MPN and packaging
- Validate contact family and wire gauge
- Inspect FA samples (Fit & Retention)
- Approve tooling and assembly process
Integration Tips
Design clearances for 600 V. Implement strain relief and clear circuit ID labeling. Pre-production should include hipot testing and functional burn-in.
