Part Overview
The 3M 960248-6202-AR is a 48-position rectangular receptacle connector with 0.100" (2.54mm) pitch, designed for through-hole PCB mounting with gold-plated mating contacts. This connector operates across -25°C to 105°C and supports 2A current at 1000VDC. The part is classified as obsolete, necessitating identification of active equivalent and substitute components that maintain electrical and mechanical compatibility for board-to-board applications.

Substitute Part Grouping Explanation
Substitution eligibility is determined by the following mandatory parameters:
- Position Count and Pitch: All substitutes maintain 48 positions at 0.100" (2.54mm) mating pitch with 2-row configuration
- Mounting and Termination: All substitutes use through-hole mounting with solder termination
- Contact Finish - Mating: Substitutes are grouped by gold or tin finish; gold-finish parts directly replace the 960248-6202-AR
- Electrical Ratings: Current rating of 2A and voltage rating of 1000VDC are preserved across all gold-finish substitutes
- Flammability Compliance: All substitutes maintain UL94 V-0 rating
Substitutes are organized into two primary groups: gold-finish receptacles (direct electrical equivalents) and tin-finish receptacles (alternative contact finish for cost or application-specific requirements).

Frequently Asked Questions (FAQ)
Q: Can 76342-324CLF, 76342-324HLF, and 76342-324LF be used as direct replacements for the 960248-6202-AR?
A: Yes. These parts maintain the same 48-position, 0.100" pitch, 2-row configuration, through-hole solder termination, and gold mating contact finish. All three carry UL94 V-0 flammability certification and RoHS compliance. Minor variations in insulation height (0.275" vs. 0.280") and contact post length (0.114" vs. 0.118") fall within acceptable mechanical tolerances for board-to-board applications. Operating temperature range is not specified for these parts.
Q: What is the difference between the Amphenol ICC Dubox™ 68683 series variants?
A: The 68683 series differs by mating contact finish: 68683-224 and 68683-624 feature gold finish, while 68683-424 features tin finish. All maintain 48 positions, 0.100" pitch, 2-row configuration, 1000V rating, and UL94 V-0 compliance. Contact finish thickness varies: 68683-224 has 15.0µin (0.38µm), while 68683-424 and 68683-624 have 100.0µin (2.54µm) and 30.0µin (0.76µm) respectively.
Q: Are the 76342 series parts with RoHS compliance suitable for all applications?
A: The 76342 series (76342-324CLF, 76342-324HLF, 76342-324LF, 76342-424HLF, 76342-424LF) are RoHS compliant and carry UL94 V-0 certification. However, operating temperature range is not specified for these parts. Verify compatibility with your application's thermal requirements before selection.
Q: What is the significance of the contact finish thickness variations?
A: Contact finish thickness affects durability and wear resistance. The 960248-6202-AR specifies flash gold finish. Substitutes with thicker gold plating (30.0µin or higher) provide enhanced contact durability. Tin-finish alternatives (76342-424HLF, 76342-424LF) with 78.7µin thickness offer cost reduction but require compatibility verification with mating connector materials.
Q: Can tin-finish receptacles replace the gold-finish 960248-6202-AR?
A: Tin-finish substitutes (68683-424, 76342-424HLF, 76342-424LF) maintain the same 48-position, 0.100" pitch, 2-row configuration and solder termination. However, contact finish material differs, which may affect corrosion resistance and long-term reliability depending on environmental exposure and mating connector composition. Verify compatibility with your specific application requirements.
Q: Why does the 2-534206-4 have a higher insulation height than the original part?
A: The 2-534206-4 (TE Connectivity AMPMODU Mod II) specifies 0.320" (8.13mm) insulation height compared to the 960248-6202-AR at 0.280" (7.10mm). This dimensional difference may affect PCB layout and stacking height in multi-connector assemblies. Verify clearance compatibility before substitution.
Q: What is the dual-entry configuration of the 68682-624?
A: The 68682-624 supports bottom or top entry mating, providing flexibility in connector orientation during assembly. This feature does not affect electrical compatibility but may simplify board design in space-constrained applications. All other electrical and mechanical parameters align with the 48-position, 0.100" pitch standard.
