3M 960250-6303-AR Equivalent & Substitute Parts

Part Overview

The 3M 960250-6303-AR is a 50-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 with a 2A current rating and 1000VDC voltage rating. The part is classified as obsolete, making equivalent substitutes necessary for ongoing design support and procurement.

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical 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)
Termination (Solder)
Fastening type (Push-Pull)
Style (Board to Board or Board to Board/Cable)

Substitute parts meeting these core parameters are functionally compatible with the 960250-6303-AR. Variations in contact finish (gold vs. tin), contact material composition, insulation material, and operating temperature ranges do not prevent mechanical and electrical substitution when the above parameters align.

Engineering Selection Recommendations

All listed substitute parts maintain mechanical and electrical compatibility with the 960250-6303-AR based on core connector parameters. Selection should prioritize active product status for long-term availability and support.

Molex C-Grid III Series (0901512150, 0901512250, 0901512350): These parts are active products with extended operating temperature ranges (-55°C to 105°C or -55°C to 125°C) and higher current ratings (3A). The 0901512250 provides gold mating contact finish matching the original specification. RoHS3 compliance is available.

TE Connectivity AMPMODU Series (2-147424-5, 2-534236-5): These connectors offer extended operating temperature ranges (-65°C to 125°C or -65°C to 105°C) and are active products. The 2-147424-5 maintains the 2A current rating of the original part. RoHS compliance status is non-compliant for both parts.

Amphenol ICC Dubox Series (87606-325LF, 89891-425LF): These active products feature UL94 V-0 flammability rating and RoHS compliance. The 87606-325LF provides gold mating contact finish. Operating temperature and current rating specifications are not provided in the datasheet.

Frequently Asked Questions (FAQ)

Q: Can I substitute the 960250-6303-AR with any of these parts directly?

A: Yes. All listed parts share the same 50-position, 0.100" pitch, 2-row configuration with through-hole solder termination and push-pull fastening. Mechanical and electrical compatibility is maintained across all substitutes.

Q: What is the difference between gold and tin contact finishes?

A: Contact finish affects corrosion resistance and contact resistance characteristics. Gold-plated contacts (0901512250, 0901512350, 2-147424-5, 2-534236-5, 87606-325LF) provide superior corrosion resistance. Tin-plated contacts (0901512150, 89891-425LF) are suitable for general-purpose applications with adequate environmental protection.

Q: Are there compliance differences between substitutes?

A: Yes. Molex (0901512150, 0901512250, 0901512350) and Amphenol ICC (87606-325LF, 89891-425LF) parts are RoHS compliant. TE Connectivity parts (2-147424-5, 2-534236-5) are RoHS non-compliant. Select based on your application's regulatory requirements.

Q: What about operating temperature ranges?

A: The original 960250-6303-AR operates -25°C to 105°C. Molex substitutes extend to -55°C to 105°C. TE Connectivity parts offer -65°C to 125°C (2-147424-5) or -65°C to 105°C (2-534236-5). Amphenol ICC operating temperature specifications are not provided. Select based on your thermal environment requirements.

Q: Does current rating matter for my application?

A: The original part is rated 2A. Molex substitutes are rated 3A, providing higher current capacity. TE Connectivity 2-147424-5 matches the 2A rating. Amphenol ICC current ratings are not specified. Verify your application's current requirements before selection.

Q: What packaging options are available?

A: Molex parts are supplied in tubes. TE Connectivity 2-147424-5 is supplied in tubes. TE Connectivity 2-534236-5 packaging is not specified. Amphenol ICC parts are supplied in tubes. Confirm packaging requirements with your procurement process.
