Substitute Part Grouping Explanation

Substitution of the 3M 961244-6300-AR-TP is based on strict electrical and mechanical compatibility criteria. All substitute parts must maintain the following core parameters:

44 positions in a 2-row configuration
0.100" (2.54mm) mating pitch and row spacing
Male pin contact type
Square contact shape
Surface mount termination with solder connection
Push-pull fastening mechanism
Unshrouded design
Board-to-board or board-to-cable style compatibility
UL94 V-0 flammability rating
Black insulation color

The Samtec TSM-122 series connectors meet these core requirements. Variations within the TSM-122 series differ in contact finish specifications, insulation material composition, and packaging formats, which do not affect fundamental electrical or mechanical compatibility for standard board-to-board interconnection applications.

Engineering Selection Recommendations

All Samtec TSM-122 series connectors listed are active products with ROHS3 compliance, providing long-term availability and regulatory alignment superior to the obsolete 3M 961244-6300-AR-TP. The substitute parts maintain identical electrical and mechanical specifications for mating pitch, row spacing, contact configuration, and fastening mechanism.

The Samtec TSM-122 series offers an extended operating temperature range of -55°C to 125°C, which encompasses the original 3M component's -25°C to 105°C specification. All substitute parts carry UL94 V-0 flammability certification and MSL 1 moisture sensitivity rating, matching the original component's environmental compliance profile.

Selection among the TSM-122 variants should be based on specific packaging requirements and contact finish specifications for your application. Parts designated with "-L-DV" feature tin post finish, while "-G-DV" and "-H-DV" variants provide gold post finish with varying thickness specifications. Packaging options include Tape & Reel (TR), Tube, and bulk formats.

Frequently Asked Questions (FAQ)

Q: Are all Samtec TSM-122 variants electrically interchangeable with the 3M 961244-6300-AR-TP?

A: Yes. All listed TSM-122 variants maintain identical mating pitch (0.100"), row spacing (0.100"), position count (44), row configuration (2), contact type (male pin), and fastening mechanism (push-pull). Electrical performance is equivalent for standard board-to-board interconnection applications.

Q: What is the difference between TSM-122-01-L-DV and TSM-122-01-G-DV?

A: The primary difference is contact finish specification. TSM-122-01-L-DV features gold mating finish (10.0µin) with tin post finish. TSM-122-01-G-DV features gold mating finish (10.0µin) with gold post finish (3.00µin). TSM-122-01-H-DV provides thicker gold mating finish (30.0µin) with gold post finish (3.00µin). These variations do not affect mechanical compatibility.

Q: Does packaging format affect connector compatibility?

A: No. Packaging format (Tape & Reel, Tube, or bulk) affects only handling, storage, and assembly processes. Electrical and mechanical connector specifications remain identical regardless of packaging selection.

Q: Why is the operating temperature range of Samtec substitutes wider than the original 3M part?

A: The Samtec TSM-122 series is rated for -55°C to 125°C operation. This extended range fully encompasses the original 3M 961244-6300-AR-TP specification of -25°C to 105°C, providing additional design margin and environmental flexibility without compromising compatibility.

Q: Are there any position-loaded variants available?

A: Yes. TSM-122-01-F-DV-A-019-P-TR, TSM-122-01-L-DV-001, and TSM-122-01-L-DV-020 are available with 43 positions loaded instead of all 44 positions. These variants are mechanically and electrically compatible for applications requiring partial position loading.

Q: What is the significance of the "-A-019" designation in part numbers?

A: The "-A-019" suffix indicates board guide feature inclusion. TSM-122-01-F-DV-A-019-P-TR, TSM-122-01-G-DV-A, TSM-122-01-L-DV-A-019-P-TR, and TSM-122-01-L-DV-A-019-TR include board guide features for enhanced alignment during assembly. Standard variants without this designation function identically for mating applications.
