Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment with the following core parameters:

• Pitch - Mating: 0.100" (2.54mm) — exact match required
• Number of Positions: 11 — exact match required
• Number of Rows: 1 — exact match required
• Mounting Type: Surface Mount — exact match required
• Termination: Solder — exact match required
• Contact Type: Male Pin — exact match required
• Style: Board to Board or Board to Board/Cable compatible — acceptable
• Shrouding: Unshrouded — exact match required
• Material Flammability Rating: UL94 V-0 — exact match required

All substitute parts listed meet these criteria. Variations in contact material, insulation material, contact finish, and operating temperature range are permitted within the substitution framework, as these do not affect mechanical or electrical compatibility at the mating interface.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts are functionally equivalent to the 3M 961111-6300-AR-TP based on critical mating parameters. Selection among active alternatives should be based on the following factors:

Product Status: The original 3M part is obsolete. All substitute parts carry active product status, ensuring ongoing availability and manufacturer support.

Compliance & Certifications: All substitute parts are ROHS3 compliant and carry UL94 V-0 flammability ratings. The Harwin M20-8771146 provides the narrowest operating temperature range (-40°C ~ 105°C), while Samtec variants extend to -55°C ~ 125°C, offering broader thermal performance.

Packaging Considerations: Harwin M20-8771146 is supplied in bulk packaging. Samtec TSM-111-01-F-SV is supplied in tube packaging. Samtec variants with "-P-TR" designation are supplied in tape and reel format, suitable for automated assembly. Selection depends on production volume and assembly methodology.

Contact Material & Finish: The original part features copper alloy contacts with gold mating finish. Harwin uses brass contacts with tin finish. Samtec variants use phosphor bronze contacts with gold mating finish. All combinations maintain electrical compatibility at the 2.54mm pitch interface.

Insulation Material: The original part uses thermoplastic insulation. Harwin uses polyamide (PA6T) nylon 6T. Samtec variants use liquid crystal polymer (LCP). All materials meet UL94 V-0 requirements.

Frequently Asked Questions (FAQ)

Q: Can I substitute the 3M 961111-6300-AR-TP with any of the listed parts?

A: Yes. All listed parts meet the core substitution criteria: 11 positions, 0.100" (2.54mm) pitch, single row, surface mount, solder termination, unshrouded, square contacts, and UL94 V-0 flammability rating. Mechanical and electrical compatibility is assured at the mating interface.

Q: What is the difference between Samtec TSM-111-01-F-SV and TSM-111-01-L-SV-A?

A: Both parts are functionally equivalent. The "-F-" designation indicates a forward-facing contact configuration, while "-L-" indicates a long contact configuration. The "-A" suffix on TSM-111-01-L-SV-A indicates board guide features. Selection depends on PCB layout requirements and mechanical constraints.

Q: Does packaging format affect electrical performance?

A: No. Packaging format (bulk, tube, tape and reel) affects supply chain logistics and assembly automation compatibility, not electrical or mechanical performance. Tape and reel packaging ("-P-TR" designation) is optimized for pick-and-place assembly.

Q: Are the Samtec parts with reduced position loading (10 of 11 positions) compatible?

A: Parts with reduced position loading (TSM-111-01-L-SV-001 and TSM-111-01-L-SV-004-P-TR) are not direct substitutes for the 3M part, which has all 11 positions loaded. These variants are listed in the source data but do not meet the substitution criteria for this application.

Q: What is the significance of the extended operating temperature range in Samtec parts?

A: Samtec variants operate from -55°C ~ 125°C, compared to the original 3M part at -25°C ~ 105°C. This extended range provides design margin for applications with broader thermal requirements. However, if your application operates within -25°C ~ 105°C, all parts are functionally equivalent in this regard.

Q: Can I use the Harwin M20-8771146 in high-temperature applications?

A: The Harwin part operates to 105°C maximum, matching the original 3M specification. For applications requiring operation above 105°C, Samtec variants with -55°C ~ 125°C rating are required.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All active substitute parts listed carry ROHS3 compliance certification. The original 3M part status is not specified in the provided data.
