Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSW-104-12-S-D-LC is determined by the following critical parameters:

• Connector Type, Contact Type, and Position Count: All substitute parts must be headers with male pins in 8-position configuration
• Pitch and Row Spacing: Mating pitch of 0.100" (2.54mm) and row spacing of 0.100" (2.54mm) are mandatory for mechanical compatibility
• Mounting and Termination: Through-hole mounting with solder termination required
• Operating Temperature Range: -55°C ~ 125°C operational envelope
• Compliance Standards: ROHS3 compliance and UL94 V-0 flammability rating

The identified substitutes TSW-104-12-S-D and HTSW-104-12-S-D meet all critical electrical and mechanical parameters. Variations in insulation material (PBT versus LCP) and packaging format do not affect functional interchangeability within the specified parameter constraints.

Parameter Comparison

Engineering Selection Recommendations

All three parts—TSW-104-12-S-D-LC, TSW-104-12-S-D, and HTSW-104-12-S-D—are active production components from Samtec Inc. with ROHS3 compliance and UL94 V-0 flammability certification. Selection between these parts should be based on:

TSW-104-12-S-D-LC: Primary choice when packaging specification requires the -LC designation. Polybutylene Terephthalate insulation material with black color coding. Moisture sensitivity level 1 (unlimited shelf life).

TSW-104-12-S-D: Functionally equivalent to TSW-104-12-S-D-LC with identical electrical and mechanical specifications. Available in bulk packaging. Polybutylene Terephthalate insulation material with black color coding. Moisture sensitivity level 1 (unlimited shelf life).

HTSW-104-12-S-D: Functionally equivalent alternative from the HTSW series. Liquid Crystal Polymer insulation material with natural color coding. Moisture sensitivity level not applicable. Available in bulk packaging with higher current inventory (1051 units).

All three parts operate within the -55°C ~ 125°C temperature range and maintain identical contact geometry, pitch, and termination specifications. Selection may be driven by packaging requirements, insulation material preference, or inventory availability.

Frequently Asked Questions (FAQ)

Q: Can TSW-104-12-S-D be used as a direct replacement for TSW-104-12-S-D-LC?

A: Yes. Both parts share identical electrical and mechanical specifications including connector type, position count, pitch, row spacing, contact geometry, and operating temperature range. The primary difference is packaging format.

Q: What is the functional difference between PBT and LCP insulation materials in these headers?

A: Both Polybutylene Terephthalate (PBT) and Liquid Crystal Polymer (LCP) meet the UL94 V-0 flammability requirement and operate within the specified -55°C ~ 125°C temperature range. Material selection does not affect electrical or mechanical interchangeability for this connector application.

Q: Is the HTSW-104-12-S-D compatible with applications designed for TSW-104-12-S-D-LC?

A: Yes. The HTSW-104-12-S-D maintains all critical parameters: 8-position configuration, 0.100" (2.54mm) pitch and row spacing, through-hole solder termination, identical contact geometry, and -55°C ~ 125°C operating temperature. The HTSW series designation and LCP insulation material do not affect functional compatibility.

Q: Are there any compliance or certification differences between these parts?

A: All three parts are ROHS3 compliant and carry UL94 V-0 flammability certification. ECCN and HTSUS classifications are identical across all three parts.

Q: What is the significance of Moisture Sensitivity Level (MSL) differences?

A: TSW-104-12-S-D-LC and TSW-104-12-S-D both have MSL 1 (unlimited shelf life), indicating no moisture sensitivity constraints. HTSW-104-12-S-D lists MSL as not applicable, reflecting the LCP insulation material's inherent moisture resistance characteristics.

Q: Can these headers be used interchangeably in production assembly?

A: Yes, provided the application does not specify a particular series designation or packaging requirement. All three parts meet identical electrical and mechanical specifications for board-to-board or cable connection applications.
