Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 3M 961129-6300-AR-TP are selected based on strict electrical and mechanical compatibility criteria. The following parameters must match or be compatible:

• Connector Type: Header with male pin contact type
• Pitch - Mating: 0.100" (2.54mm)
• Number of Positions: 29
• Number of Rows: 1
• Mounting Type: Surface Mount
• Termination: Solder
• Fastening Type: Push-Pull
• Contact Shape: Square
• Insulation Material: Thermoplastic or equivalent
• Material Flammability Rating: UL94 V-0
• Insulation Color: Black
• Moisture Sensitivity Level: 1 (Unlimited)

The Samtec TSM series connectors meet these criteria with active product status and enhanced operating temperature ranges. Variations within the TSM-129 family differ in contact finish thickness, contact length specifications, and optional features such as board lock capability.

Parameter Comparison

Engineering Selection Recommendations

All Samtec TSM-129 series connectors listed are active products with ROHS3 compliance, providing long-term availability and regulatory alignment. The primary selection criteria are:

For standard applications: TSM-129-01-L-SV or TSM-129-01-LM-SV provide gold-plated mating contacts with enhanced operating temperature range (-55°C ~ 125°C) compared to the original 3M part (-25°C ~ 105°C). TSM-129-01-LM-SV is packaged in tubes for production environments.

For temperature-constrained designs: TSM-129-01-T-SV maintains the original operating temperature range (-55°C ~ 105°C) with tin-plated mating contacts and is suitable for applications where the upper temperature limit of 105°C is specified.

For applications requiring mechanical retention: TSM-129-01-S-SV-LC includes board lock features while maintaining all electrical and mechanical compatibility parameters.

For cost-optimized designs: TSM-129-01-F-SV and TSM-129-01-S-SV offer variations in contact finish thickness with active product status and full compliance certifications.

All substitute parts maintain the critical parameters: 29-position, 0.100" pitch, surface mount, solder termination, push-pull fastening, square contact shape, UL94 V-0 flammability rating, and MSL 1 classification.

Frequently Asked Questions (FAQ)

Q: Can TSM-129 series connectors directly replace the 3M 961129-6300-AR-TP?

A: Yes. All TSM-129 variants listed maintain electrical and mechanical compatibility through matching pitch (0.100"), position count (29), contact type (male pin), mounting method (surface mount), termination (solder), and fastening type (push-pull). The primary differences are in contact finish specifications and operating temperature ranges.

Q: What is the difference between TSM-129-01-L-SV and TSM-129-01-LM-SV?

A: Both parts are electrically and mechanically identical. The primary difference is packaging: TSM-129-01-LM-SV is supplied in tube packaging suitable for automated production environments, while TSM-129-01-L-SV uses standard packaging. Contact finish thickness is 10.0µin (0.25µm) for both.

Q: Why do some TSM-129 variants have different contact finish thicknesses?

A: Contact finish thickness variations (3.00µin, 10.0µin, 30.0µin) provide options for different application requirements and cost structures. All variants maintain the same electrical performance and compatibility with the original 3M connector.

Q: Is TSM-129-01-T-SV suitable for all applications?

A: TSM-129-01-T-SV is suitable for applications where the operating temperature range of -55°C ~ 105°C is acceptable. This part uses tin plating on mating contacts instead of gold. For applications requiring the extended upper temperature limit of 125°C, select TSM-129-01-F-SV, TSM-129-01-L-SV, TSM-129-01-LM-SV, or TSM-129-01-S-SV.

Q: What does the Board Lock feature in TSM-129-01-S-SV-LC provide?

A: The board lock feature provides mechanical retention between the connector and mating component, preventing accidental disconnection. This is specified in the Features field as "Board Lock" and is the only functional difference from TSM-129-01-S-SV.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All Samtec TSM-129 series connectors listed are ROHS3 compliant, meeting current regulatory requirements for hazardous substance restrictions.

Q: What is the significance of the insulation material change from Thermoplastic to Liquid Crystal Polymer (LCP)?

A: Liquid Crystal Polymer provides superior thermal and mechanical properties compared to standard thermoplastic materials. LCP offers better dimensional stability, higher temperature capability, and improved chemical resistance, contributing to the extended operating temperature range (-55°C ~ 125°C) of the TSM-129 series.
