The 0901310156 is a 72-position, dual-row breakaway header from the Molex C-Grid III 90131 series.
Tin-Plated Contacts for Moderate-Cycle Duty
This thickness is well above typical flash tin (40-80 µinch), providing a robust contact interface for applications with up to a few hundred mating cycles — suitable for automotive harnesses that are mated during assembly and rarely disconnected in service. Tin plating is cost-effective compared to gold, but in high-vibration or corrosive environments, the tin oxide layer can increase contact resistance over time. For sealed or low-current signal paths, this is acceptable; for high-current power circuits, gold-plated alternatives in the same series should be considered.
Through-Hole Solder Termination with UL94 V-0 Housing
The through-hole solder termination (0.114" post length) provides a mechanically robust joint on the PCB, suitable for wave-solder assembly.
No official cross-reference or pin-compatible replacement is listed. The base product number 090131 covers the C-Grid III 90131 family; other position counts or plating options in that family may be considered for design flexibility.
