Substitute Part Grouping Explanation

Substitution for the 960108-8100-AR-TP is based on the following critical parameters that must remain constant:

Connector type: Receptacle with female socket contacts
Number of positions: 8 positions
Pitch: 0.100" (2.54mm) mating pitch
Mounting: Surface mount, right-angle configuration
Termination: Solder
Fastening: Push-pull mechanism
Contact finish: Gold plating on mating surface
Style: Board-to-board or board-to-cable compatibility

The Samtec Tiger Claw™ SSM series satisfies these core requirements. Substitute variants differ in the following allowed parameters:

Number of positions loaded (7 or 8)
Contact finish thickness on mating surface
Insulation material (Liquid Crystal Polymer vs. Thermoplastic)
Operating temperature range
Current rating per contact
Voltage rating
Additional features (board lock option)

Engineering Selection Recommendations

All Samtec Tiger Claw™ SSM series substitutes listed maintain active product status and ROHS3 compliance, ensuring long-term availability and regulatory alignment. The following selection criteria apply:

For full 8-position loading with standard features:

SSM-108-F-SH: Standard configuration without board lock feature
SSM-108-F-SH-LC: Includes board lock for enhanced mechanical retention
SSM-108-FM-SH: Alternative standard configuration

For 7-position loading applications:

SSM-108-L-SH-001-TR through SSM-108-L-SH-006: Various 7-position loaded configurations with thicker gold plating (10.0µin vs. 3.00µin)
SSM-108-L-SH-002-TR, SSM-108-L-SH-003-TR, SSM-108-L-SH-004-TR, SSM-108-L-SH-005-TR: Tape reel packaging variants

All substitutes exceed the original part's electrical specifications (higher current rating: 5.2A per contact vs. 2A; extended operating temperature: -55°C to 125°C vs. -25°C to 105°C). Samtec parts use Liquid Crystal Polymer insulation, providing superior thermal and mechanical properties compared to the original thermoplastic material.

Frequently Asked Questions (FAQ)

Q: Can SSM-108 series connectors directly replace the 960108-8100-AR-TP in existing designs?

A: Yes, for applications requiring 8 positions fully loaded. The SSM-108-F-SH, SSM-108-F-SH-LC, and SSM-108-FM-SH maintain identical pitch, mounting orientation, and contact configuration. PCB footprints are compatible. For designs using only 7 positions, the SSM-108-L-SH series variants are appropriate.

Q: What is the difference between SSM-108-F-SH and SSM-108-F-SH-LC?

A: The LC variant includes a board lock feature for enhanced mechanical retention during mating cycles. Both maintain identical electrical and pitch specifications. Selection depends on application requirements for mechanical security.

Q: Why do SSM-108-L-SH variants show 7 positions loaded instead of 8?

A: These variants are designed for applications requiring only 7 active signal positions. The connector shell accommodates 8 positions, but only 7 are populated with contacts. This allows flexibility in circuit design without requiring a different connector footprint.

Q: Are there packaging differences among the Samtec substitutes?

A: Yes. SSM-108-F-SH is supplied in tube packaging. Most SSM-108-L-SH variants are available in tape reel format (indicated by -TR suffix), which is standard for high-volume surface mount assembly. Verify packaging requirements with your procurement specification.

Q: How do the electrical ratings compare?

A: Samtec SSM-108 series parts exceed the original 960108-8100-AR-TP specifications. Current rating increases from 2A to 5.2A per contact, and voltage rating changes from 1000VDC to 405VAC/572VDC. These higher ratings provide design margin and are fully backward compatible for applications within the original specifications.

Q: What is the significance of contact finish thickness differences?

A: The original part specifies flash gold plating. Samtec substitutes offer either 3.00µin (standard SSM-108-F-SH series) or 10.0µin (SSM-108-L-SH series) gold thickness. Thicker plating provides enhanced durability for high-cycle mating applications. Both exceed minimum requirements for the specified 2A current rating.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All Samtec Tiger Claw™ SSM series parts listed are ROHS3 compliant, meeting current environmental and regulatory requirements. The original 3M part status is not specified for ROHS compliance.
