960120-8100-AR-TP Equivalent & Substitute Parts

Part Overview

The 3M 960120-8100-AR-TP is a 20-position 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.

The part operates across -25°C to 105°C with a 2A current rating and 1000VDC voltage rating. It features push-pull fastening, solder termination, and UL94 V-0 flammability rating. With 1128 pieces in stock, substitution options are available from active product lines that maintain electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Samtec Inc. Tiger Claw™ SSM series connectors provide direct functional equivalence to the 960120-8100-AR-TP. Substitution is based on the following critical parameters that must remain constant:

20-position receptacle configuration
0.100" (2.54mm) mating pitch
Surface mount, right-angle mounting
Female socket contact type
Solder termination
Push-pull fastening mechanism
Gold-plated mating contacts
Black insulation
Square contact geometry

All listed Samtec substitutes maintain these core parameters. Variations exist in contact finish thickness, number of loaded positions, packaging format, and optional board lock features. These variations do not affect fundamental electrical or mechanical compatibility for standard board-to-board applications.

Engineering Selection Recommendations

All Samtec Tiger Claw™ SSM series substitutes are active products with ROHS3 compliance, providing long-term design support and procurement stability compared to the obsolete 3M 960120-8100-AR-TP.

For applications requiring full 20-position loading with standard gold finish:

SSM-120-F-SH: Minimum gold thickness (3.00µin), standard configuration
SSM-120-FM-SH: Identical to SSM-120-F-SH with alternative designation
SSM-120-L-SH-LC: Full loading with board lock feature, 10.0µin gold thickness, tube packaging
SSM-120-L-SH-LC-TR: Full loading with board lock feature, tape & reel packaging
SSM-120-L-SH-TR: Full loading, 10.0µin gold thickness, tape & reel packaging
SSM-120-LM-SH: Full loading, 10.0µin gold thickness
SSM-120-LM-SH-LC: Full loading with board lock feature, 10.0µin gold thickness

For applications with 19-position loading:

SSM-120-L-SH-010: 19-position loading, 10.0µin gold thickness
SSM-120-L-SH-010-TR: 19-position loading, 10.0µin gold thickness, tape & reel packaging
SSM-120-S-SH-010: 19-position loading, 30.0µin gold thickness (enhanced durability)

All substitutes operate across -55°C to 125°C, exceeding the original -25°C to 105°C range. Current rating increases from 2A to 5.2A per contact. Voltage rating of 572VDC is suitable for applications originally rated at 1000VDC where the connector is not the limiting component.

Frequently Asked Questions (FAQ)

Q: Can SSM-120 series connectors directly replace the 960120-8100-AR-TP in existing designs?

A: Yes. All SSM-120 variants maintain the same 20-position, 0.100" pitch, surface mount right-angle configuration with female socket contacts and solder termination. Mechanical and electrical compatibility is preserved for board-to-board applications.

Q: What is the difference between 19-position and 20-position loaded variants?

A: 19-position loaded variants (SSM-120-L-SH-010, SSM-120-L-SH-010-TR, SSM-120-S-SH-010) have one position without a contact installed. These are suitable only for applications that do not require all 20 positions. Full 20-position loading is required for standard board-to-board interconnect.

Q: How do gold finish thickness variations affect connector performance?

A: Gold finish thickness is specified as flash (original part), 3.00µin, 10.0µin, or 30.0µin. Thicker gold finishes provide enhanced durability in high-cycle mating applications. All thicknesses provide equivalent electrical performance for standard applications.

Q: What is the significance of the board lock feature (LC designation)?

A: Board lock (LC) variants include a mechanical locking feature that prevents accidental connector separation. This is an optional enhancement and does not affect electrical compatibility. Selection depends on application requirements for mechanical retention.

Q: What packaging options are available?

A: Samtec SSM-120 connectors are supplied in standard packaging, tape & reel (TR designation), or tube format (LC designation with tube packaging). Packaging selection depends on assembly process requirements and volume.

Q: Are all SSM-120 variants ROHS3 compliant?

A: Yes. All listed Samtec Tiger Claw™ SSM-120 substitutes are ROHS3 compliant, meeting current environmental and regulatory requirements.

Q: How do operating temperature ranges compare?

A: The original 960120-8100-AR-TP operates -25°C to 105°C. All SSM-120 substitutes operate -55°C to 125°C, providing extended temperature capability suitable for broader application environments.
