Substitute Part Grouping Explanation

Substitution for the 3M 961238-6300-AR-TP is based on strict electrical and mechanical compatibility criteria. All substitute parts must maintain the following core parameters:

38 positions in 2-row configuration
0.100" (2.54mm) mating pitch and row spacing
Male pin contact type
Surface mount termination with solder connection
Push-pull fastening mechanism
Square contact shape
UL94 V-0 flammability rating
Unshrouded design
Board-to-board or cable connectivity style

The Samtec TSM series connectors listed below meet these core requirements. Variations in contact finish thickness, insulation material (LCP vs. thermoplastic), operating temperature range, and packaging format represent allowable substitutions based on application requirements. The TSM-119 base series provides active product status alternatives to the obsolete 3M connector.

Engineering Selection Recommendations

All Samtec TSM-119 series connectors listed provide direct functional equivalence to the obsolete 3M 961238-6300-AR-TP. Selection among substitute parts should be based on the following criteria:

Product Status & Compliance: All substitute parts carry active product status with ROHS3 compliance, ensuring long-term availability and regulatory alignment. The 3M original component is obsolete, making substitution necessary for new designs and ongoing production.

Operating Temperature Range: Samtec TSM-119 series connectors operate across -55°C to 125°C, exceeding the original 3M specification of -25°C to 105°C. This extended range provides additional thermal margin for demanding applications.

Contact Finish Variations: Substitute parts offer three contact finish options for mating surfaces: flash gold (TSM-119-01-F-DV), standard gold at 10.0µin (TSM-119-01-G-DV, TSM-119-01-L-DV), and heavy gold at 30.0µin (TSM-119-01-H-DV). Selection depends on application durability and mating cycle requirements.

Insulation Material: Samtec parts use Liquid Crystal Polymer (LCP) instead of thermoplastic, providing superior dimensional stability and thermal performance. This material change is transparent to electrical function.

Packaging & Assembly Considerations: Parts designated with "-P" include pick-and-place features. Tape & Reel (TR) packaging is available for high-volume automated assembly. TSM-119-01-L-DV-001 loads 37 of 38 positions for applications requiring a single position omission.

Contact Finish - Post: TSM-119-01-G-DV and TSM-119-01-H-DV feature gold post finish, while TSM-119-01-F-DV and TSM-119-01-L-DV series use tin post finish. Post finish selection depends on soldering process compatibility and long-term reliability requirements.

Frequently Asked Questions (FAQ)

Q: Can I directly replace the 3M 961238-6300-AR-TP with any Samtec TSM-119 connector?

A: Yes, all listed Samtec TSM-119 connectors maintain the core electrical and mechanical parameters required for direct substitution: 38 positions, 2.54mm pitch, surface mount solder termination, and push-pull fastening. Differences in contact finish thickness, insulation material, and packaging do not affect functional compatibility.

Q: What is the difference between TSM-119-01-L-DV and TSM-119-01-L-DV-P?

A: Both connectors are electrically and mechanically identical. The "-P" designation indicates pick-and-place features for automated assembly equipment. Select TSM-119-01-L-DV-P for high-volume production requiring automated placement; select TSM-119-01-L-DV for manual assembly or lower-volume applications.

Q: Why do some substitute parts have different contact finish thicknesses?

A: Contact finish thickness affects durability under repeated mating cycles and environmental exposure. Flash gold (TSM-119-01-F-DV) at 3.00µin suits applications with limited mating cycles. Standard gold at 10.0µin (TSM-119-01-G-DV, TSM-119-01-L-DV) provides balanced durability. Heavy gold at 30.0µin (TSM-119-01-H-DV) is specified for high-cycle or harsh-environment applications.

Q: What is the significance of the "-A" suffix in TSM-119-01-G-DV-A and TSM-119-01-L-DV-A-P-TR?

A: The "-A" designation indicates board guide features for improved alignment during assembly. This is an optional enhancement that does not affect electrical function or compatibility with the original 3M connector.

Q: Is Tape & Reel (TR) packaging compatible with my existing assembly process?

A: Tape & Reel packaging is designed for automated pick-and-place equipment. If your assembly process uses tube or bulk packaging, select non-TR variants (TSM-119-01-L-DV-P or TSM-119-01-L-DV). Both packaging formats contain identical connectors.

Q: Why is the operating temperature range of Samtec parts wider than the original 3M connector?

A: Samtec TSM-119 series connectors are rated -55°C to 125°C due to superior insulation material (LCP) and contact material (phosphor bronze) compared to the original thermoplastic and copper alloy design. This extended range is a material improvement that does not affect compatibility.

Q: What does "Number of Positions Loaded: 37" mean for TSM-119-01-L-DV-001?

A: This variant is manufactured with 37 of 38 possible contact positions populated. Use this part only if your application requires a single position to remain empty. For standard 38-position applications, select other TSM-119-01-L-DV variants.

Q: Are all substitute parts RoHS compliant?

A: Yes, all Samtec TSM-119 series connectors listed are ROHS3 compliant. The original 3M part does not specify RoHS status. Samtec compliance ensures regulatory alignment for new designs and markets with RoHS requirements.
