3M 960250-7102-AR: Equivalent & Substitute Parts Reference

Part Overview

The 3M 960250-7102-AR is a 50-position rectangular receptacle connector with 0.100" (2.54mm) pitch, designed for through-hole, right-angle board-to-board applications. This connector features gold-plated mating contacts, solder termination, and push-pull fastening. The part is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. Active alternatives from Molex, TE Connectivity, and Samtec provide direct functional equivalence while maintaining current product support and availability.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict adherence to the following core parameters:

Critical Matching Parameters:

Connector type: Receptacle
Contact type: Female socket
Number of positions: 50
Pitch - mating: 0.100" (2.54mm)
Number of rows: 2
Row spacing - mating: 0.100" (2.54mm)
Mounting type: Through hole, right angle
Termination: Solder
Fastening type: Push-pull
Contact shape: Square

All substitute parts listed meet these core electrical and mechanical requirements. Variations in secondary parameters such as contact finish thickness, insulation material composition, and operating temperature range do not disqualify substitution when the primary mating and mounting characteristics remain identical.

Engineering Selection Recommendations

Molex 0719730225 is suitable for applications requiring active product support and ROHS3 compliance. This connector operates within -40°C to 105°C, which covers standard industrial temperature ranges but does not extend to the upper limit of the original 3M part. Molex provides pick-and-place features for automated assembly.

TE Connectivity 2-102278-4 meets military specification MIL-DTL-55302 and is classified as AMPMODU Mod II. This part is ROHS3 compliant and maintains active product status. Operating temperature range is not specified in available documentation.

Samtec BCS-125 Series (variants F-D-HE, S-D-HE, SM-D-HE, FM-D-HE, LM-D-HE, L-D-HE-001, L-D-HE-021, T-D-HE) provides the broadest operating temperature range of -55°C to 125°C, matching or exceeding the original part's upper temperature limit. All variants are ROHS3 compliant and REACH unaffected. The BCS-125-T-D-HE variant features tin mating contact finish instead of gold. Samtec variants with "L" designation (L-D-HE-001, L-D-HE-021) are loaded with 49 positions instead of 50.

Selection should prioritize active product status and ROHS3 compliance for new designs. Temperature range requirements and contact finish specifications should guide final selection among available substitutes.

Frequently Asked Questions (FAQ)

Q: Can the 3M 960250-7102-AR be directly replaced with any of these substitutes?

A: Direct mechanical and electrical replacement is possible with all listed substitutes. All parts share identical pitch (0.100"), position count (50), row configuration (2 rows), mounting style (through-hole right-angle), and fastening mechanism (push-pull). Physical board layout compatibility requires verification of insulation height and contact post length specifications.

Q: What is the difference between Samtec BCS-125 variants?

A: Samtec BCS-125 variants differ in contact finish thickness and position loading. The "F" variant (BCS-125-F-D-HE) features 3.00µin gold finish. The "S" and "SM" variants feature 30.0µin gold finish. The "L" variants (L-D-HE-001, L-D-HE-021) are loaded with 49 positions instead of 50. The "T" variant (BCS-125-T-D-HE) uses tin mating contact finish instead of gold. All variants maintain identical pitch, row spacing, and mounting characteristics.

Q: Does the Molex 0719730225 operate at the same temperature range as the original 3M part?

A: The Molex 0719730225 operates from -40°C to 105°C, which does not reach the upper limit of the 3M part (-25°C to 125°C). For applications requiring operation above 105°C, Samtec BCS-125 series variants are rated to 125°C.

Q: Are all substitutes RoHS compliant?

A: All active substitute parts listed are ROHS3 compliant. The original 3M 960250-7102-AR RoHS status is not specified in available documentation.

Q: What packaging options are available?

A: Molex 0719730225 is supplied in tube packaging. Samtec BCS-125-S-D-HE and BCS-125-T-D-HE are supplied in tube packaging. Samtec BCS-125-F-D-HE is supplied in bulk packaging. Other Samtec variants have packaging not specified in available documentation.

Q: Can I use the Samtec BCS-125-T-D-HE with tin finish instead of gold finish?

A: The BCS-125-T-D-HE features tin mating contact finish instead of gold. This substitution is valid from a mechanical and electrical standpoint. Contact finish selection should be based on application requirements for corrosion resistance and signal integrity.
