TSM-104-02-T-SH-A Equivalent & Substitute Parts

Part Overview

The TSM-104-02-T-SH-A is a surface mount right-angle rectangular connector header manufactured by Samtec Inc. This 4-position connector operates across -55°C to 105°C and features a 0.100" (2.54mm) pitch with solder termination and push-pull fastening. The part is active in production with ROHS3 compliance and UL94 V-0 flammability rating. Substitute parts may be required due to inventory constraints, lead time considerations, or specific application requirements within compatible electrical and mechanical parameters.

Substitute Part Grouping Explanation

Substitution of the TSM-104-02-T-SH-A is limited by strict mechanical and electrical compatibility requirements. The primary substitute identified is the GEC02SBSN-M89 from Sullins Connector Solutions. However, this substitute exhibits a critical parameter deviation that restricts its application scope.

The GEC02SBSN-M89 differs in the following key parameters:

• Number of Positions: 2 (versus 4 on the main part)
• Contact Length - Mating: 0.230" (5.84mm) (versus 0.320" (8.13mm) on the main part)
• Insulation Height: 0.140" (4.66mm) (versus 0.120" (3.05mm) on the main part)
• Insulation Material: Polyamide (PA9T), Nylon 9T (versus Liquid Crystal Polymer (LCP) on the main part)
• Operating Temperature Range: -65°C ~ 150°C (versus -55°C ~ 105°C on the main part)

Due to the position count mismatch (2 versus 4), the GEC02SBSN-M89 cannot serve as a direct functional equivalent. Substitution is only valid in applications where a 2-position connector meets the circuit requirements.

Parameter Comparison

Engineering Selection Recommendations

The GEC02SBSN-M89 shares critical mechanical and electrical compatibility with the TSM-104-02-T-SH-A in pitch, mounting type, termination method, and fastening mechanism. Both parts maintain ROHS3 compliance, UL94 V-0 flammability rating, and MSL 1 moisture sensitivity classification.

Selection of the GEC02SBSN-M89 as a substitute is valid only when circuit design accommodates a 2-position connector configuration. The substitute's wider operating temperature range (-65°C ~ 150°C) provides extended thermal performance compared to the main part. The polyamide insulation material differs from the main part's liquid crystal polymer, which may affect mechanical and thermal properties in specific applications.

Both parts are active in production status with established supply chains and full RoHS3 compliance certification.

Frequently Asked Questions (FAQ)

Q: Can the GEC02SBSN-M89 directly replace the TSM-104-02-T-SH-A in all applications?

A: No. The GEC02SBSN-M89 is a 2-position connector while the TSM-104-02-T-SH-A is a 4-position connector. Direct substitution is only possible in circuits designed for 2-position connectivity.

Q: What are the critical compatibility parameters between these parts?

A: Both connectors share 0.100" (2.54mm) pitch, surface mount right-angle mounting, solder termination, push-pull fastening, phosphor bronze contacts, and UL94 V-0 flammability rating. These parameters ensure mechanical and electrical interface compatibility where position count permits.

Q: How do the insulation materials differ?

A: The TSM-104-02-T-SH-A uses Liquid Crystal Polymer (LCP) insulation, while the GEC02SBSN-M89 uses Polyamide (PA9T), Nylon 9T. Both materials meet UL94 V-0 requirements, but LCP typically offers superior thermal and mechanical properties.

Q: Does the GEC02SBSN-M89 support the full operating temperature range of the TSM-104-02-T-SH-A?

A: Yes. The GEC02SBSN-M89 operates across -65°C ~ 150°C, which encompasses the TSM-104-02-T-SH-A range of -55°C ~ 105°C.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the TSM-104-02-T-SH-A and GEC02SBSN-M89 are ROHS3 compliant with MSL 1 moisture sensitivity classification.

Q: What packaging differences exist between these parts?

A: The TSM-104-02-T-SH-A is supplied in tube packaging, while the GEC02SBSN-M89 is supplied in bulk packaging. This affects handling and inventory management but does not impact electrical or mechanical performance.
