3M 961128-6300-AR-TP Equivalent & Substitute Parts

Part Overview

The 3M 961128-6300-AR-TP is a rectangular connector header for surface mount applications, featuring 28 positions at 0.100" (2.54mm) pitch. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and production continuity. The part functions as a board-to-board connector with male pin contacts, gold-plated mating surfaces, and solder termination suitable for high-reliability applications requiring UL94 V-0 flammability compliance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 961128-6300-AR-TP is determined by the following critical parameters:

• Connector Type & Contact Configuration: Header with male pin contacts
• Pitch and Position Count: 0.100" (2.54mm) pitch with 28 positions in single row
• Mounting Technology: Surface mount solder termination
• Contact Finish: Gold-plated mating surface
• Flammability Compliance: UL94 V-0 rating
• Electrical Performance: 2A current rating capability

All Samtec TSM-128 series parts listed below meet these core substitution criteria. Variations exist in contact material composition (phosphor bronze vs. copper alloy), insulation material (liquid crystal polymer vs. thermoplastic), operating temperature range, and optional features (board guide, board lock, pick and place compatibility).

Parameter Comparison

Engineering Selection Recommendations

All Samtec TSM-128 series parts provide functional equivalence to the obsolete 3M 961128-6300-AR-TP. Selection among substitute options depends on specific application requirements:

TSM-128-01-F-SV: Baseline equivalent with no additional features. Suitable for applications where standard board-to-board or cable connectivity is required without mechanical guidance or locking mechanisms.

TSM-128-01-L-SV-A and TSM-128-01-S-SV-A: Include board guide feature for improved mechanical alignment during mating. The TSM-128-01-L-SV-A variant uses longer contact length (0.230"), while TSM-128-01-S-SV-A provides standard configuration with board guide.

TSM-128-01-L-SV-LC and TSM-128-01-S-SV-LC: Incorporate board lock feature for positive mechanical retention. These variants are appropriate for applications requiring secure connector positioning and resistance to accidental disconnection.

TSM-128-01-S-SV-A-P: Includes board guide feature with pick-and-place compatibility and tube packaging. This variant is optimized for automated assembly processes and high-volume production environments.

All substitute parts exceed the original operating temperature range (-55°C to 125°C vs. -25°C to 105°C) and provide ROHS3 compliance. The shift from thermoplastic to liquid crystal polymer insulation material in Samtec parts offers improved thermal and chemical resistance characteristics.

Frequently Asked Questions (FAQ)

Q: Are all TSM-128 variants electrically compatible with the 3M 961128-6300-AR-TP?

A: Yes. All listed Samtec TSM-128 variants maintain identical pitch (0.100"), position count (28), contact type (male pin), and mating surface finish (gold). Electrical performance is equivalent across all variants.

Q: What is the difference between board guide and board lock features?

A: Board guide variants (TSM-128-01-L-SV-A, TSM-128-01-S-SV-A, TSM-128-01-S-SV-A-P) provide mechanical alignment assistance during connector mating. Board lock variants (TSM-128-01-L-SV-LC, TSM-128-01-S-SV-LC) add positive retention mechanisms to prevent accidental disconnection after mating.

Q: Does the change from thermoplastic to liquid crystal polymer insulation affect compatibility?

A: No. The material change does not affect electrical or mechanical compatibility. LCP insulation provides superior thermal stability and chemical resistance compared to thermoplastic, making it suitable for more demanding environmental conditions.

Q: What is the significance of the contact length difference (0.210" vs. 0.230")?

A: The Samtec variants feature slightly longer mating contact length (0.230" vs. 0.100" original). This provides improved contact engagement and is within standard tolerance for 2.54mm pitch connectors. Mechanical fit with mating receptacles designed for standard 2.54mm pitch remains compatible.

Q: Which variant should be selected for automated assembly?

A: TSM-128-01-S-SV-A-P is specifically configured for pick-and-place automation with tube packaging and board guide feature. This variant optimizes handling and placement accuracy in high-volume manufacturing environments.

Q: Are all variants ROHS3 compliant?

A: Yes. All Samtec TSM-128 substitute parts are ROHS3 compliant. The original 3M part does not specify RoHS status.

Q: What is the inventory status of substitute parts?

A: All Samtec TSM-128 variants are active production parts with current inventory availability ranging from 748 to 1105 pieces in stock.
