Engineering Selection Recommendations

All Samtec TSM-112 series parts listed are active, production-qualified alternatives to the obsolete 3M 961224-6700-AR-TP. Selection among substitute parts depends on specific application requirements:

For standard applications: TSM-112-02-G-DV provides a direct functional equivalent with gold plating on both mating and post contacts, enhanced operating temperature range (-55°C to 125°C versus -25°C to 105°C), and ROHS3 compliance.

For automated assembly: TSM-112-02-FM-DV-A-P-TR or TSM-112-02-L-DV-A-P-TR include pick-and-place features and tape & reel packaging for high-volume production environments.

For applications requiring mechanical retention: TSM-112-02-G-DV-LC or TSM-112-02-L-DV-LC-TR incorporate board lock features for enhanced mechanical stability.

For cost-optimized designs: TSM-112-02-F-DV offers reduced contact finish thickness while maintaining all core electrical and mechanical specifications.

All substitute parts maintain UL94 V-0 flammability rating, MSL 1 moisture sensitivity, and identical pitch, position count, and row spacing. The Samtec TSM-112 series cuttable header design provides additional flexibility for custom connector configurations.

Frequently Asked Questions (FAQ)

Q: What are the critical parameters that determine substitution compatibility?

A: The following parameters must match exactly: pitch (0.100" / 2.54mm), number of positions (24), number of rows (2), row spacing (0.100" / 2.54mm), connector type (header), contact type (male pin), mounting type (surface mount), termination (solder), and fastening type (push-pull). All listed Samtec TSM-112 parts meet these requirements.

Q: How does contact length variation affect compatibility?

A: The 3M 961224-6700-AR-TP has a mating contact length of 0.260" (6.60mm). Samtec TSM-112-01-L-DV provides 0.230" (5.84mm), while most other TSM-112 variants provide 0.320" (8.13mm). Contact length affects mating depth and insertion force characteristics. Longer contacts provide greater engagement depth; shorter contacts reduce insertion force. Selection depends on mating connector specifications and PCB layout constraints.

Q: What is the difference between tin and gold post finishes?

A: The 3M part uses tin post finish. TSM-112-02-G-DV, TSM-112-02-G-DV-A, and TSM-112-02-G-DV-LC variants use gold post finish, which provides enhanced corrosion resistance and solderability. TSM-112-02-F-DV, TSM-112-02-FM-DV-A-P-TR, TSM-112-02-L-DV-A-P-TR, TSM-112-02-L-DV-LC-TR, and TSM-112-02-L-DV-P-TR maintain tin post finish for cost optimization.

Q: What packaging options are available?

A: Most TSM-112 variants are supplied in tube packaging. TSM-112-02-FM-DV-A-P-TR, TSM-112-02-L-DV-A-P-TR, TSM-112-02-L-DV-LC-TR, and TSM-112-02-L-DV-P-TR are supplied in tape & reel (TR) format, suitable for automated pick-and-place assembly.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All Samtec TSM-112 series parts listed are ROHS3 compliant. The original 3M part does not specify RoHS status.

Q: What is the significance of the cuttable header design?

A: The Samtec TSM-112 series features cuttable header construction, allowing custom connector configurations by cutting the header to required position counts. This provides design flexibility not available with the fixed 24-position 3M part.

Q: How do board guide and board lock features differ?

A: Board guide features (TSM-112-02-F-DV-A, TSM-112-02-G-DV-A, TSM-112-02-FM-DV-A-P-TR, TSM-112-02-L-DV-A-P-TR) provide mechanical alignment during mating. Board lock features (TSM-112-02-G-DV-LC, TSM-112-02-L-DV-LC-TR) provide positive mechanical retention after mating, preventing accidental disconnection.

Q: What is the operating temperature advantage of Samtec parts?

A: The 3M 961224-6700-AR-TP operates from -25°C to 105°C. All Samtec TSM-112 substitutes operate from -55°C to 125°C, providing extended temperature range for demanding applications.
