Substitute Part Grouping Explanation

Substitute parts are identified strictly based on matching these determinative parameters for rectangular connectors: connector type, contact type, pitch - mating, number of rows, mounting type, termination, mating/contact shape, and style. Substitution candidates also maintain comparable mechanical features such as shrouding status, insulation material/color, material flammability rating, and moisture sensitivity level. Differences in secondary attributes are documented for engineering assessment.

Engineering Selection Recommendations

Samtec TSW-129-14-S-S is an active and ROHS3 compliant part, with REACH unaffected status. Substitute 4-102972-0 from TE Connectivity AMP Connectors is listed as obsolete and not ROHS applicable, with vendor undefined REACH status. All mechanical and electrical parameters relevant for substitution are provided above; selection should be based strictly on product availability, required certifications, and compliance status per project requirements.

Frequently Asked Questions (FAQ)

Q1: What are the primary substitution criteria for Samtec TSW-129-14-S-S in rectangular connector headers?
A1: Substitution is determined by matching connector type, contact type, pitch - mating, number of rows, mounting type, termination, mating/contact shape, insulation properties, fastening type, and compliance attributes.

Q2: Is the electrical/mechanical compatibility between TSW-129-14-S-S and 4-102972-0 established by the provided data?
A2: Yes, the provided parameters confirm similarities in core connector features and mounting approaches, with distinctions in position count and some material/finish details explicitly listed.

Q3: When selecting between active and obsolete substitute parts, what engineering factors should be considered?
A3: Component selection should reference the product status, environmental compliance (RoHS, REACH), and inventory levels, as documented in the part overview and parameter table.

Q4: Are packaging or MSL levels relevant for substitution in this connector category?
A4: Both parts are offered in bulk packaging and rated at MSL 1 (Unlimited), confirming suitability for standard PCB assembly and storage practices within this product category.

Q5: Does the number of positions impact the direct substitution in applications?
A5: The number of positions is a critical mechanical parameter. Substitute parts offer 40 positions versus 29; design adaptation is required if a direct positional match is essential. Only parameters explicitly provided define the interchangeability scope.
