Engineering Selection Recommendations
All Samtec TSM-125 series substitute parts maintain active product status, ensuring long-term availability and manufacturing support. The transition from thermoplastic to Liquid Crystal Polymer (LCP) insulation material in substitute parts provides enhanced thermal and mechanical performance. Operating temperature range expansion from -25°C ~ 105°C to -55°C ~ 125°C in substitute parts accommodates extended environmental specifications.
All substitute parts carry ROHS3 compliance certification, meeting current regulatory requirements for electronic component manufacturing. The UL94 V-0 flammability rating is maintained across all alternatives, preserving safety certifications for the original application.
Contact material change from Copper Alloy to Phosphor Bronze in substitute parts represents a standard industry upgrade that maintains electrical conductivity and contact reliability. Phosphor Bronze provides superior spring characteristics and wear resistance in push-pull connector applications.
For applications requiring specific features, select substitute parts as follows:
TSM-125-01-F-SV provides baseline compatibility with minimal feature set and tube packaging.
TSM-125-01-L-SV-A includes Board Guide feature for enhanced mechanical alignment during mating operations.
TSM-125-01-SM-SV offers standard configuration with tube packaging for high-volume procurement.
TSM-125-01-G-SV features gold post finish for enhanced corrosion resistance in demanding environments.
TSM-125-01-S-SV-A combines Board Guide feature with increased gold finish thickness (30.0µin) for superior contact durability.
Frequently Asked Questions (FAQ)
Q: Can TSM-125 series connectors directly replace the 3M 961125-6300-AR-TP in existing designs?
A: Yes. All TSM-125 substitute parts maintain identical pitch (0.100" / 2.54mm), position count (25), contact type (male pin), and mounting method (surface mount solder). The connectors are mechanically and electrically compatible for board-to-board applications. Minor dimensional increases in contact length and insulation height fall within standard connector tolerance ranges and do not affect PCB layout or mating interface compatibility.
Q: What is the significance of the "Cuttable" designation in TSM-125 series connectors?
A: The cuttable feature allows the connector header to be segmented into smaller position counts after manufacturing, providing design flexibility. This does not affect the full 25-position configuration when used as a complete assembly.
Q: How do contact finish variations affect connector performance?
A: Contact finish thickness variations (3.00µin to 30.0µin gold plating) do not alter electrical performance or mating force characteristics. Thicker gold finishes (TSM-125-01-S-SV-A at 30.0µin) provide extended contact life in high-cycle mating applications. All finishes maintain the same electrical conductivity and corrosion resistance properties required for reliable signal transmission.
Q: What is the difference between TSM-125-01-L-SV-A and TSM-125-01-S-SV-A?
A: Both parts include Board Guide feature. TSM-125-01-L-SV-A has 10.0µin gold finish thickness with tin post finish. TSM-125-01-S-SV-A has 30.0µin gold finish thickness with tin post finish. The increased gold plating in TSM-125-01-S-SV-A provides enhanced durability for applications requiring extended mating cycles.
Q: Are all substitute parts ROHS3 compliant?
A: Yes. All Samtec TSM-125 series substitute parts carry ROHS3 compliance certification, meeting current regulatory requirements for hazardous substance restrictions in electronic components.
Q: What packaging options are available for TSM-125 substitute parts?
A: TSM-125-01-F-SV and TSM-125-01-SM-SV are supplied in tube packaging. TSM-125-01-L-SV-A is supplied in tube packaging. TSM-125-01-G-SV-P, TSM-125-01-L-SV-A-P, TSM-125-01-S-SV-A, TSM-125-01-S-SV-A-001, TSM-125-01-S-SV-LC, and TSM-125-01-LM-SV have packaging designations not specified in standard tube format. Verify packaging requirements with supplier documentation for specific procurement needs.
Q: Does the operating temperature range expansion affect design considerations?
A: The extended operating temperature range (-55°C ~ 125°C) in substitute parts exceeds the original specification (-25°C ~ 105°C). This provides additional thermal margin for applications in extreme environments. Existing designs operating within the original temperature range require no modification.
