Parameter Comparison

Engineering Selection Recommendations

The Samtec TSW-120-14-F-D is a qualified substitute for the TE Connectivity 1-103542-9 based on the following engineering criteria:

Compliance and Certification Alignment: Both parts maintain ROHS3 compliance and UL94 V-0 flammability ratings, ensuring regulatory requirements are satisfied in applications requiring these certifications. Both parts carry MSL 1 (Unlimited) moisture sensitivity classification, indicating no special handling requirements during storage or assembly.

Electrical and Mechanical Compatibility: The substitute part matches all critical connector specifications: 40-position, 2-row header configuration with 0.100" (2.54mm) pitch spacing, through-hole mounting, unshrouded design, and push-pull fastening. Contact geometry, mating contact length, and gold-plated mating surfaces are identical. Operating temperature range of -55°C to 125°C is maintained.

Product Status Consideration: The TE Connectivity 1-103542-9 is designated Last Time Buy, indicating production discontinuation. The Samtec TSW-120-14-F-D maintains Active product status, ensuring long-term availability and continued manufacturing support for new designs and production requirements.

Material Differences: The substitute employs phosphor bronze contacts and polybutylene terephthalate (PBT) insulation material, compared to copper alloy contacts and thermoplastic insulation in the original part. Both material selections satisfy the specified operating temperature range and flammability requirements.

Frequently Asked Questions (FAQ)

Q: Can the Samtec TSW-120-14-F-D be used as a direct replacement for the TE Connectivity 1-103542-9 in existing designs?

A: Yes. Both connectors share identical pitch spacing (0.100" / 2.54mm), position count (40), row configuration (2 rows), contact geometry (square male pins), and mating contact length (0.320" / 8.13mm). The connectors are mechanically and electrically compatible for board-to-board and cable interconnection applications.

Q: What are the differences in contact material between these two parts?

A: The TE Connectivity 1-103542-9 uses copper alloy contacts, while the Samtec TSW-120-14-F-D uses phosphor bronze contacts. Both materials are suitable for the specified operating temperature range (-55°C to 125°C) and maintain gold plating on mating surfaces.

Q: Are there differences in insulation material?

A: Yes. The TE Connectivity part uses thermoplastic insulation, while the Samtec substitute uses polybutylene terephthalate (PBT). Both materials achieve UL94 V-0 flammability rating and support the operating temperature range.

Q: Do both parts support the same termination methods?

A: The TE Connectivity 1-103542-9 supports both press-fit and solder termination. The Samtec TSW-120-14-F-D supports solder termination only. For applications requiring press-fit termination, the original part specification must be maintained.

Q: What is the difference in packaging between these parts?

A: The TE Connectivity 1-103542-9 is supplied in bulk packaging, while the Samtec TSW-120-14-F-D is supplied in bag packaging. Packaging format does not affect connector functionality or compatibility.

Q: Are both parts RoHS compliant?

A: Yes. Both the TE Connectivity 1-103542-9 and Samtec TSW-120-14-F-D are ROHS3 compliant, meeting regulatory requirements for restricted substance elimination.

Q: What is the current rating for the Samtec substitute?

A: The current rating for the Samtec TSW-120-14-F-D is not specified in the provided technical data. The TE Connectivity 1-103542-9 is rated for 3A per contact. For applications with specific current requirements, contact rating specifications must be obtained from the manufacturer.

Q: Do both connectors have the same moisture sensitivity level?

A: Yes. Both parts carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity restrictions and no special handling requirements during storage or assembly processes.
