Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the TST-103-01-G-S is determined by strict adherence to the following electrical and mechanical parameters:

• Connector Type & Contact Configuration: Header with male pin contacts
• Position Count & Row Configuration: 3 positions in single row arrangement
• Pitch Specification: 0.100" (2.54mm) mating pitch
• Mounting Technology: Through-hole termination on printed circuit board
• Shrouding Design: 4-wall shrouded housing
• Fastening Mechanism: Push-pull engagement system
• Contact Material & Finish: Phosphor bronze with gold plating on mating surface
• Insulation Composition: PBT glass-filled material
• Thermal Range: -55°C to 125°C operating envelope
• Current Capacity: 3.4A per individual contact
• Compliance Standards: UL94 V-0 flammability rating and ROHS3 compliance

Any substitute part must match all specified parameters without deviation. No substitute parts are currently available in the provided dataset.

Parameter Comparison

No substitute parts are available for comparison at this time. The TST-103-01-G-S remains the specified component for this application requirement.

Engineering Selection Recommendations

The TST-103-01-G-S is classified as an Active product with full ROHS3 compliance and UL94 V-0 flammability certification. These compliance certifications ensure suitability for regulated applications and environments with stringent material requirements. The component's MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints during storage or handling. When no direct substitutes are available, component selection should prioritize maintaining the specified electrical ratings (3.4A per contact), mechanical pitch tolerance (0.100"), and thermal operating range (-55°C to 125°C) to ensure circuit performance and reliability.

Frequently Asked Questions (FAQ)

Q: What defines compatibility for TST-103-01-G-S substitutes? A: Substitute parts must match the 3-position, single-row configuration at 0.100" pitch with through-hole mounting, 4-wall shrouding, push-pull fastening, phosphor bronze contacts with gold plating, and 3.4A current rating per contact.

Q: Are there mechanical compatibility concerns when selecting alternatives? A: Yes. The contact length specifications (0.250" mating, 0.115" post, 0.480" overall) and insulation height (0.350") must be maintained to ensure proper board-to-cable/wire connection geometry and mating interface alignment.

Q: Does the operating temperature range affect substitute selection? A: The -55°C to 125°C operating range is a critical parameter. Any substitute must support this full thermal envelope to maintain electrical performance and contact integrity across the specified temperature extremes.

Q: What role does the UL94 V-0 rating play in substitution? A: The UL94 V-0 flammability certification is mandatory for applications requiring fire-resistant materials. Substitute parts must carry equivalent or superior flammability ratings to maintain compliance with applicable safety standards.

Q: How does ROHS3 compliance impact part selection? A: ROHS3 compliance is a regulatory requirement for many markets and applications. Substitute parts must maintain ROHS3 certification status to ensure legal and contractual compliance in the supply chain.

Q: Why is the contact finish specification important? A: Gold plating on mating contacts (10.0µin thickness) ensures reliable electrical connection, corrosion resistance, and low contact resistance. This specification must be maintained in any substitute to preserve signal integrity and connection reliability.
