3M 960128-8100-AR-TP Equivalent & Substitute Parts

Part Overview

The 3M 960128-8100-AR-TP is a 28-position rectangular receptacle connector with 0.100" (2.54mm) pitch, surface mount right-angle configuration, and gold-plated mating contacts. This connector is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement continuity. The part operates across -25°C to 105°C with a 2A current rating per contact and 1000VDC voltage rating.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts are qualified based on the following critical parameters that determine functional compatibility:

• Connector Type & Contact Type: All substitutes are receptacle connectors with female socket contacts
• Number of Positions & Pitch: All substitutes maintain 28 positions at 0.100" (2.54mm) pitch
• Mounting Configuration: All substitutes are surface mount, right-angle connectors
• Termination & Fastening: All substitutes use solder termination with push-pull fastening
• Contact Material & Finish: Substitutes are grouped by mating contact finish (gold or tin) and material composition
• Insulation Material: Samtec substitutes use Liquid Crystal Polymer (LCP) versus 3M's thermoplastic
• Operating Temperature Range: Samtec substitutes extend to -55°C ~ 125°C, exceeding 3M specifications
• Current & Voltage Ratings: Samtec substitutes provide 5.2A per contact and 405VAC/572VDC ratings

Parameter Comparison

Engineering Selection Recommendations

All Samtec Tiger Claw™ SSM series substitutes are active production parts with ROHS3 compliance, providing long-term availability and regulatory alignment. The 3M 960128-8100-AR-TP is obsolete, making these substitutes necessary for new designs and ongoing production support.

Gold-Plated Contact Finish Options:

• SSM-128-F-SH: Minimum gold thickness (3.00µin / 0.076µm)
• SSM-128-FM-SH: Minimum gold thickness with mid-range specification
• SSM-128-LM-SH: Medium gold thickness (10.0µin / 0.25µm)
• SSM-128-SM-SH: Standard gold thickness (30.0µin / 0.76µm)

Tin-Plated Contact Finish Options:

• SSM-128-T-SH: Tin finish, standard specification
• SSM-128-TM-SH: Tin finish, mid-range specification

All Samtec substitutes exceed the original 3M specifications in current rating (5.2A versus 2A) and operating temperature range (-55°C to 125°C versus -25°C to 105°C). Contact material differs (phosphor bronze versus copper alloy) and insulation material is upgraded to Liquid Crystal Polymer (LCP) for improved thermal and chemical resistance.

Frequently Asked Questions (FAQ)

Q: Are Samtec SSM-128 series connectors mechanically compatible with the 3M 960128-8100-AR-TP?

A: Yes. Both maintain identical 28-position configuration, 0.100" (2.54mm) pitch, surface mount right-angle mounting, and push-pull fastening. Insulation height differs by 0.002" (0.02mm), which is within typical PCB tolerance ranges.

Q: What is the difference between the gold-plated variants (SSM-128-F-SH, SSM-128-FM-SH, SSM-128-LM-SH, SSM-128-SM-SH)?

A: The variants differ in gold plating thickness on mating contacts. SSM-128-F-SH has the thinnest plating (3.00µin), while SSM-128-SM-SH has the thickest (30.0µin). Thicker plating provides enhanced wear resistance for high-cycle mating applications. All meet the same electrical specifications.

Q: Can I use the tin-plated variants (SSM-128-T-SH, SSM-128-TM-SH) as direct replacements for the gold-plated 3M part?

A: Tin-plated contacts have different electrical and corrosion characteristics compared to gold-plated contacts. Selection depends on application requirements for contact resistance, corrosion environment, and mating cycle expectations. Both finishes are electrically functional within the specified voltage and current ratings.

Q: What are the key electrical differences between the 3M part and Samtec substitutes?

A: Samtec substitutes provide higher current capacity (5.2A per contact versus 2A) and extended operating temperature range (-55°C to 125°C versus -25°C to 105°C). Voltage ratings differ: Samtec specifies 405VAC and 572VDC, while 3M specifies 1000VDC. Application voltage requirements determine suitability.

Q: Are all Samtec SSM-128 variants ROHS3 compliant?

A: Yes. All Samtec Tiger Claw™ SSM-128 variants listed are ROHS3 compliant. The original 3M part does not specify RoHS compliance status.

Q: What is the difference in insulation material, and does it affect compatibility?

A: The 3M part uses thermoplastic insulation, while Samtec substitutes use Liquid Crystal Polymer (LCP). LCP provides superior thermal stability, chemical resistance, and dimensional consistency. This material upgrade does not affect mechanical or electrical compatibility for standard applications.

Q: Which Samtec variant should I select for my application?

A: Selection depends on three factors: (1) contact finish requirement (gold or tin), (2) gold plating thickness if gold-plated contacts are specified, and (3) environmental and mating cycle conditions. For applications originally designed for the 3M gold-plated part, SSM-128-SM-SH (standard gold thickness) provides equivalent performance with enhanced durability.
