Substitute Part Grouping Explanation

Substitution of the 3M 961224-6300-AR-TP is based on the following critical parameters that must remain constant across all equivalent parts:

Connector type: Header with male pin contacts
Position count and row configuration: 24 positions in 2 rows
Mating pitch and row spacing: 0.100" (2.54mm)
Mounting method: Surface mount with solder termination
Fastening mechanism: Push-pull

Engineering Selection Recommendations

All Samtec TSM-112 series variants listed provide functional equivalence to the obsolete 3M 961224-6300-AR-TP. Selection among substitute parts depends on specific application requirements and supply chain considerations:

TSM-112-01-F-DV-004-TR provides the baseline equivalent with 23 positions loaded and standard gold mating finish. This variant is suitable for applications where partial loading is acceptable.

TSM-112-01-F-DV-A-P-TR includes all 24 positions loaded with board guide and pick-and-place features, supporting automated assembly processes.

TSM-112-01-L-DV offers tube packaging with all positions loaded and enhanced gold plating thickness (10.0µin), suitable for manual handling and applications requiring higher contact durability.

TSM-112-01-S-DV-A-TR combines all positions loaded with board guide features and standard gold plating (30.0µin) in tape-and-reel format.

TSM-112-01-SS-DV provides all positions loaded with standard gold plating in bulk packaging format.

TSM-112-01-T-DV-P-TR features tin mating finish with pick-and-place compatibility and maintains the original operating temperature range (-55°C ~ 105°C). This variant is appropriate for cost-sensitive applications where gold plating is not required.

All substitute parts carry ROHS3 compliance and UL94 V-0 flammability certification, meeting modern regulatory requirements. The Samtec TSM series offers extended operating temperature ranges (-55°C ~ 125°C for most variants) compared to the original 3M part (-25°C ~ 105°C), providing enhanced thermal performance for demanding environments.

Frequently Asked Questions (FAQ)

Q: Are all TSM-112 variants mechanically compatible with the 3M 961224-6300-AR-TP?

A: Yes. All listed TSM-112 variants maintain identical mating pitch (0.100"), row spacing (0.100"), position count (24 in 2 rows), and push-pull fastening. Mechanical interchangeability is confirmed across all variants.

Q: What is the difference between the contact finish options?

A: The 3M original part features gold mating finish. Most TSM-112 variants (F, S, SS models) provide gold finish with varying thickness specifications (3.00µin to 30.0µin). The TSM-112-01-T-DV-P-TR variant uses tin mating finish, reducing material cost while maintaining electrical performance for non-corrosive environments.

Q: How do packaging options affect part selection?

A: Tape & Reel (TR) packaging supports automated pick-and-place assembly. Tube packaging accommodates manual handling and lower-volume applications. The TSM-112-01-L-DV tube variant provides the highest inventory availability (1506 Pcs). Packaging selection does not affect electrical or mechanical performance.

Q: What is the significance of "Cuttable" in the TSM connector type?

A: The Samtec TSM series features cuttable design, allowing custom length configurations from the standard 24-position header. This flexibility supports applications requiring non-standard position counts without tooling changes.

Q: Does the insulation material change affect compatibility?

A: The original 3M part uses thermoplastic insulation; all TSM-112 substitutes use Liquid Crystal Polymer (LCP). LCP provides superior thermal stability, dimensional consistency, and flammability performance. This material change enhances reliability without affecting mechanical or electrical compatibility.

Q: Which variant best matches the original 3M part specifications?

A: TSM-112-01-S-DV-A-TR most closely aligns with the original part, featuring all 24 positions loaded, gold mating finish, and board guide support. For applications with strict thermal requirements matching the original (-25°C ~ 105°C), TSM-112-01-T-DV-P-TR maintains this exact temperature range.

Q: Are all substitutes RoHS compliant?

A: Yes. All listed Samtec TSM-112 variants carry ROHS3 compliance certification, meeting current environmental and regulatory standards. The original 3M part does not specify RoHS status.
