Substitute Part Grouping Explanation

Substitution eligibility for the 66925-565 is determined by strict equivalence across the following critical parameters:

130-position receptacle configuration
0.100" (2.54mm) mating pitch and row spacing
Through-hole, right-angle mounting
Solder termination with push-pull fastening
Gold-plated mating contacts
Square contact geometry
Female socket contact type

The substitute parts 2-532956-0, 7-532956-0, and 6-87962-4 meet these core electrical and mechanical requirements. Variations in secondary parameters such as insulation material composition, contact post finish, and flammability ratings do not affect functional interchangeability within the specified connector class.

Engineering Selection Recommendations

All three substitute parts (2-532956-0, 7-532956-0, and 6-87962-4) are functionally equivalent to the 66925-565 based on core connector specifications. Selection should be based on the following criteria:

2-532956-0 and 7-532956-0: Both are active AMPMODU Mod II series connectors with RoHS compliance. These parts are suitable for applications requiring modern regulatory compliance. The primary difference between these two is packaging format (both supplied in tubes).

6-87962-4: This part carries MIL-DTL-55302 military specification qualification and RoHS compliance. It features a higher gold plating thickness (50.0µin versus 30.0µin) on mating contacts, providing enhanced durability for high-cycle mating applications. This part is appropriate for military, aerospace, or high-reliability industrial applications.

For new designs or production requiring RoHS compliance, 2-532956-0 or 7-532956-0 are the primary recommendations. For applications with military specifications or enhanced contact durability requirements, 6-87962-4 is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Can the 66925-565 be directly replaced with 2-532956-0 or 7-532956-0?

A: Yes. Both parts share identical mating pitch (0.100"), row spacing (0.100"), position count (130), mounting configuration (through-hole right-angle), and contact geometry (square, gold-plated). The connectors are mechanically and electrically interchangeable.

Q: What is the difference between 2-532956-0 and 7-532956-0?

A: Both parts are identical AMPMODU Mod II receptacles with the same electrical and mechanical specifications. The difference is packaging format; both are supplied in tubes. Selection between these two does not affect connector performance.

Q: Why does 6-87962-4 have thicker gold plating?

A: The 6-87962-4 features 50.0µin (1.27µm) gold plating on mating contacts compared to 30.0µin (0.76µm) on the other substitutes. This increased thickness is specified for MIL-DTL-55302 military applications and provides extended contact life under repeated mating cycles.

Q: Are all substitutes RoHS compliant?

A: The 2-532956-0 and 7-532956-0 are RoHS compliant. The 6-87962-4 is also RoHS compliant. The original 66925-565 is RoHS non-compliant. If RoHS compliance is required, any of the three substitutes are acceptable.

Q: What is the difference in insulation material between the main part and substitutes?

A: The 66925-565 uses Polyamide (PA) nylon with glass fill. The 2-532956-0 and 7-532956-0 use Polyphenylene Sulfide (PPS) with glass fill. Both materials meet UL94 flammability standards and are suitable for PCB-mounted connectors. Material selection does not affect electrical or mechanical interchangeability.

Q: Can I use 6-87962-4 in non-military applications?

A: Yes. The 6-87962-4 meets all functional requirements of the 66925-565 and exceeds them in contact durability. It is suitable for any application requiring a 130-position, 0.100" pitch receptacle connector with through-hole right-angle mounting.
