3M 961123-6700-AR-TP Equivalent & Substitute Parts

Part Overview

The 3M 961123-6700-AR-TP is a rectangular connector header designed for surface mount applications with 23 positions at 0.100" (2.54mm) pitch. This component is classified as obsolete, making equivalent substitute parts necessary for new designs, repairs, and production continuity. The connector features male pins, unshrouded design, and board-to-board connectivity with solder termination and push-pull fastening.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 961123-6700-AR-TP is determined by the following critical parameters that must match or exceed the original specification:

Core Matching Criteria:

• Number of positions: 23
• Pitch - Mating: 0.100" (2.54mm)
• Contact type: Male Pin
• Mounting type: Surface Mount
• Termination: Solder
• Fastening type: Push-Pull
• Connector style: Board to Board or Board to Board/Cable compatible
• Insulation material: Thermoplastic or equivalent polymer
• Material flammability rating: UL94 V-0
• Moisture sensitivity level: 1 (Unlimited)

Allowable Parameter Variations:

• Contact length - Mating: May exceed 0.260" (6.60mm) without functional impact
• Insulation height: May vary within standard tolerance ranges
• Contact finish thickness: Variations acceptable if gold plating is maintained
• Operating temperature range: May exceed -25°C ~ 105°C
• Current rating: May exceed 2A
• Contact material: Phosphor Bronze acceptable as alternative to Copper Alloy
• Connector type: Header with breakaway or cuttable features acceptable

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts meet the core functional requirements for replacing the obsolete 3M 961123-6700-AR-TP. Selection should be based on the following factors:

Sullins GBC23SFBN-M30: This part is actively manufactured and offers the highest current rating at 3A, exceeding the original 2A specification. It features breakaway capability and polyamide insulation material. The extended operating temperature range of -65°C ~ 150°C provides additional thermal margin. ROHS3 compliance and REACH unaffected status support regulatory requirements for new designs.

Samtec TSM-123-02-L-SV and TSM-123-02-S-SV: Both Samtec variants are actively produced with cuttable header design, offering flexibility for custom configurations. Liquid Crystal Polymer insulation provides superior thermal and mechanical properties compared to standard thermoplastic. The -55°C ~ 125°C operating range exceeds the original specification. Both parts are ROHS3 compliant. The primary difference between these two variants is the contact finish thickness on the mating surface: TSM-123-02-L-SV provides 10.0µin (0.25µm) gold plating, while TSM-123-02-S-SV provides 30.0µin (0.76µm) gold plating for enhanced durability in high-cycle mating applications.

All substitute parts maintain UL94 V-0 flammability rating, MSL 1 moisture sensitivity, and push-pull fastening compatibility with the original design.

Frequently Asked Questions (FAQ)

Q: Can the Sullins GBC23SFBN-M30 be used as a direct replacement for the 3M 961123-6700-AR-TP?

A: Yes. The GBC23SFBN-M30 matches all critical parameters including 23-position count, 0.100" (2.54mm) pitch, male pin contact type, surface mount configuration, and solder termination. The increased contact length (0.318" vs 0.260") and higher current rating (3A vs 2A) are compatible with the original application. The breakaway feature provides additional design flexibility.

Q: What is the difference between the two Samtec TSM-123 variants?

A: Both TSM-123-02-L-SV and TSM-123-02-S-SV are functionally equivalent for the 961123-6700-AR-TP replacement. The primary distinction is the gold plating thickness on the mating contact surface. The TSM-123-02-L-SV provides 10.0µin (0.25µm) plating, suitable for standard mating cycles. The TSM-123-02-S-SV provides 30.0µin (0.76µm) plating, recommended for applications requiring frequent mating and unmating cycles or enhanced wear resistance.

Q: Are there packaging differences between the substitute parts?

A: The Sullins GBC23SFBN-M30 is supplied in bulk packaging. The Samtec parts do not specify packaging format in the provided data. Contact the respective manufacturers for specific packaging options, quantities per reel, and lead times.

Q: Do all substitute parts meet RoHS compliance?

A: The Sullins GBC23SFBN-M30 and both Samtec variants are ROHS3 compliant. The original 3M part does not specify RoHS status due to its obsolete classification. For new designs subject to RoHS requirements, all three substitute options are suitable.

Q: What is the inventory availability for these parts?

A: Current inventory levels are: 3M 961123-6700-AR-TP (1038 pcs), Sullins GBC23SFBN-M30 (718 pcs), Samtec TSM-123-02-L-SV (888 pcs), and Samtec TSM-123-02-S-SV (1036 pcs). Inventory levels are subject to change; contact suppliers for current availability.

Q: Can these connectors be used interchangeably in existing PCB designs?

A: Yes, provided the PCB footprint accommodates the slightly increased contact length of the substitute parts (0.318" to 0.320" versus 0.260"). The increased insulation height (0.100" versus 0.098") is negligible for standard board-to-board spacing. Verify mating connector compatibility with the receiving connector specification.
