Key Parameters

Substitute Part Grouping Explanation

Substitution of the 3M 963123-2000-AR-TP is determined by the following critical parameters:

• Number of Positions: Must be 23 positions
• Pitch - Mating: Must be 0.100" (2.54mm)
• Mounting Type: Must be Surface Mount
• Contact Type: Must be Female Socket
• Fastening Type: Must be Push-Pull
• Contact Finish - Mating: Must be Gold
• Connector Style: Board-to-board or board-to-cable compatibility

The Samtec Tiger Claw™ SSM series provides active alternatives across multiple connector entry configurations (bottom entry, pass-through, and top entry variants). All substitute parts maintain the core 23-position, 0.100" pitch, surface mount architecture with gold-plated female sockets and push-pull fastening. Variants differ in entry configuration, number of loaded positions, contact finish thickness, and insulation material composition.

Parameter Comparison

Engineering Selection Recommendations

All Samtec Tiger Claw™ SSM series alternatives are active products with ROHS3 compliance, addressing the obsolescence of the 3M 963123-2000-AR-TP. Selection among substitute parts depends on mechanical entry configuration requirements:

SSM-123-L-SV-BE is the direct mechanical equivalent for applications requiring bottom entry configuration, matching the original connector's entry orientation while providing enhanced operating temperature range (-55°C to 125°C versus -25°C to 105°C) and higher current capacity (5.2A per contact versus 2A).

SSM-123-L-SV-TR and SSM-123-LM-SV provide pass-through entry configurations suitable for applications where connector stacking or daisy-chaining is required. These variants maintain all 23 positions loaded and support the same push-pull fastening mechanism.

SSM-123-F-SV and SSM-123-FM-SV offer pass-through entry with reduced contact finish thickness (3.00µin), suitable for cost-optimized applications where the original flash gold plating specification is not critical.

SSM-123-L-SV-010 and SSM-123-S-SV-010 variants load 22 of 23 positions, applicable only where single-position omission is acceptable for the application design.

All substitutes maintain the 0.100" (2.54mm) pitch, surface mount termination, and push-pull fastening required for mechanical and electrical compatibility with existing mating connectors and PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can SSM-123-L-SV-BE directly replace the 3M 963123-2000-AR-TP in existing designs?

A: Yes, for applications using bottom entry configuration. The SSM-123-L-SV-BE maintains identical 23-position count, 0.100" pitch, surface mount footprint, and push-pull fastening. PCB layout compatibility is confirmed. The substitute provides superior operating temperature range and current capacity.

Q: What is the difference between pass-through and bottom entry connectors?

A: Bottom entry connectors (SSM-123-L-SV-BE) accept mating plugs from the bottom side of the PCB. Pass-through connectors (SSM-123-L-SV-TR, SSM-123-LM-SV, SSM-123-F-SV, SSM-123-FM-SV) allow mating plugs to enter from either side and pass through the connector body, enabling stacking or daisy-chain configurations. Entry configuration selection depends on mechanical assembly requirements.

Q: Are there electrical performance differences between substitute options?

A: All substitutes maintain the same 23-position, 0.100" pitch electrical architecture. Current rating increases from 2A to 5.2A per contact across all Samtec alternatives. Voltage rating changes from 1000VDC to 405VAC/572VDC. Applications operating below 572VDC are electrically compatible. Contact finish thickness varies (3.00µin to 10.0µin gold plating), affecting durability in high-cycle mating environments but not baseline electrical performance.

Q: What does "Number of Positions Loaded" mean?

A: This indicates how many of the 23 available contact positions contain actual contacts. The 3M 963123-2000-AR-TP loads all 23 positions. SSM-123-L-SV-010 and SSM-123-S-SV-010 load only 22 positions, with one position left empty. This affects connector density and is application-specific; substitution is valid only if the design accommodates 22-position loading.

Q: Are all substitutes RoHS compliant?

A: Yes. All Samtec Tiger Claw™ SSM series alternatives are ROHS3 compliant. The original 3M part does not specify RoHS status. This compliance is beneficial for applications subject to RoHS regulations.

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

A: Contact finish thickness (measured in microinches) affects contact durability and wear resistance during mating cycles. The 3M original specifies flash gold (approximately 0.5µin). Samtec alternatives range from 3.00µin to 10.0µin, providing enhanced durability for high-cycle applications. Thicker finishes are suitable for applications exceeding 100 mating cycles.

Q: Can I use an SSM variant with 22 loaded positions if my application requires 23?

A: No. SSM-123-L-SV-010 and SSM-123-S-SV-010 are suitable only for applications designed to use 22 contacts. If your design requires all 23 positions, select SSM-123-L-SV-BE, SSM-123-L-SV-TR, SSM-123-LM-SV, SSM-123-F-SV, or SSM-123-FM-SV, which load all 23 positions.

Q: What is the difference between SSM-123-L-SV-TR and SSM-123-LM-SV?

A: Both are pass-through connectors with all 23 positions loaded and 10.0µin gold contact finish. The primary difference is internal contact configuration or mechanical detail not specified in the provided parameters. Both are electrically and mechanically equivalent for standard applications. Consult Samtec datasheets for specific mechanical differences if required.
