Automotive Crimp Terminal – OEM 1447221-3 | 50pcs G-Female & Female

The OEM 1447221-3 is a precision automotive crimp terminal (sheath contact) used in wire harness repair and connector assembly. Sold in 50-piece packs for G-Female (gold-plated) and standard Female variants. The G-Female variant features gold-plated contacts for superior corrosion resistance in high-reliability circuits; the standard Female variant is tin-plated for general harness repair.

Key Specifications

Why Crimp Terminals Fail

Automotive crimp terminals corrode from moisture ingress, vibration-induced fretting, and thermal cycling. Corroded or pushed-back terminals cause intermittent circuit faults, high resistance connections, and voltage drop issues. Gold-plated terminals (G-Female) provide superior corrosion resistance for ECU, sensor, and high-reliability signal circuits where tin-plated contacts may corrode prematurely.

Variant Guide

• 50pcs G-Female – 50x gold-plated female crimp contacts for high-reliability ECU and sensor circuits
• 50pcs Female – 50x tin-plated female crimp contacts for general harness repair

Use G-Female (gold-plated) for ECU, ABS module, and sensor signal circuits where corrosion resistance is critical. Use standard Female for body electrical and lighting harness repair.

Installation Notes

• Strip wire insulation to 3–4mm before crimping
• Use a ratchet crimp tool rated for the appropriate wire gauge
• Insert terminal into connector housing until the locking tab clicks
• Pull-test each terminal after insertion to verify retention

Frequently Asked Questions

Q: What is the difference between G-Female and Female?
A: G-Female terminals have gold-plated contacts for superior corrosion resistance and lower contact resistance, ideal for ECU, sensor, and high-reliability signal circuits. Standard Female terminals are tin-plated and suitable for general harness repair.

Q: What connector housings are compatible with OEM 1447221-3?
A: Cross-reference OEM 1447221-3 with your connector housing part number to confirm terminal compatibility.

Common Applications

• ECU and ABS module harness re-pinning (G-Female)
• Sensor signal circuit terminal replacement
• Body electrical harness repair (standard Female)
• High-reliability automotive wiring applications
