TSW-112-14-T-S Equivalent & Substitute Parts

Part Overview

The TSW-112-14-T-S is a rectangular connector header manufactured by Samtec Inc., designed for through-hole mounting applications. This 12-position, single-row header connector operates at 0.100" (2.54mm) pitch and is classified as an active product. The connector features unshrouded design with solder termination and push-pull fastening, suitable for board-to-board or cable interconnection in industrial and commercial applications. Equivalent parts are identified to provide procurement flexibility, inventory alternatives, and supply chain continuity.

Substitute Part Grouping Explanation

The 929700-01-12-RK manufactured by 3M qualifies as an equivalent substitute for the TSW-112-14-T-S based on the following critical parameters:

Matching Parameters:

• 12-position, single-row configuration
• 0.100" (2.54mm) mating pitch
• Through-hole solder termination
• Push-pull fastening mechanism
• Unshrouded header design
• Square contact shape
• Tin contact finish on both mating and post surfaces
• UL94 V-0 flammability rating
• RoHS compliance
• MSL 1 (Unlimited) moisture sensitivity level
• Board-to-board style application

Acceptable Variations:

• Insulation material: PCT (Polycyclohexylenedimethylene Terephthalate) substitutes for PBT
• Operating temperature lower limit: -40°C (versus -55°C) remains within acceptable industrial range
• Contact material: Copper Alloy substitutes for Phosphor Bronze
• Contact length tolerance: 0.318" (8.08mm) mating length versus 0.320" (8.13mm) is within mechanical tolerance
• Overall contact length: 0.528" (13.42mm) versus 0.530" (13.46mm) is within tolerance
• Current rating specification: 2.5A provided for substitute part

Parameter Comparison

Engineering Selection Recommendations

Both the TSW-112-14-T-S and 929700-01-12-RK are active products with full RoHS compliance and REACH unaffected status, meeting current regulatory requirements for electronic component procurement. The 3M 929700-01-12-RK offers breakaway functionality as an additional feature, providing design flexibility for applications requiring individual pin separation. The substitute part maintains UL94 V-0 flammability certification and MSL 1 moisture sensitivity rating, ensuring compatibility with standard assembly and storage protocols. The operating temperature range difference (-40°C minimum versus -55°C) is acceptable for applications not requiring extended low-temperature operation below -40°C. Both parts are suitable for direct substitution in standard through-hole PCB assembly processes with solder termination.

Frequently Asked Questions (FAQ)

Q: Can the 929700-01-12-RK be used as a direct replacement for the TSW-112-14-T-S?

A: Yes. Both connectors share identical mating pitch (0.100"), position count (12), row configuration (1), contact type (male pin), mounting method (through-hole solder), and fastening mechanism (push-pull). Mechanical and electrical compatibility is confirmed across all critical parameters.

Q: What is the significance of the breakaway feature on the 3M part?

A: The breakaway feature allows individual pins to be separated from the connector strip after assembly, providing design flexibility for applications requiring custom pin configurations. This feature does not affect compatibility with standard mating connectors.

Q: Are there temperature range limitations when substituting the 3M part?

A: The 3M 929700-01-12-RK operates from -40°C to 105°C, compared to the Samtec part's -55°C to 105°C range. Substitution is appropriate for applications operating above -40°C. Applications requiring operation below -40°C should retain the original Samtec specification.

Q: Do the different insulation materials (PBT versus PCT) affect compatibility?

A: No. Both PBT and PCT are thermoplastic materials meeting UL94 V-0 flammability requirements. PCT offers comparable mechanical and thermal properties within the specified operating range and is functionally equivalent for this application.

Q: Are both parts suitable for automated PCB assembly?

A: Yes. Both connectors are designed for standard through-hole solder termination and are compatible with conventional wave soldering and selective soldering processes. MSL 1 rating indicates no moisture sensitivity restrictions for storage or handling.

Q: What is the significance of the current rating specification on the 3M part?

A: The 3M part specifies 2.5A current rating per contact. The Samtec part does not provide a current rating specification. For applications requiring current capacity verification, the 3M specification of 2.5A per contact is available as reference data.
