Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for rectangular connector headers is determined by strict equivalence across the following parameters: connector type, contact type, number of positions, pitch spacing, mounting method, shrouding configuration, termination type, operating temperature range, current rating, and flammability rating. All identified substitute parts maintain identical specifications across these core criteria, ensuring direct functional compatibility in board-to-board and cable applications.

The substitute parts 6-103639-0 and 1-103735-0 differ from the main part in contact finish specifications and product status. These differences do not affect mechanical or electrical compatibility in standard applications. Contact finish variations (Tin-Lead, Tin, or Gold) represent material composition changes on mating and post surfaces that do not alter the fundamental connector function or performance envelope.

Engineering Selection Recommendations

6-103639-0 Selection Criteria: This substitute part is recommended for applications requiring active product status and RoHS3 compliance. The part maintains identical mechanical and electrical specifications to the main part while offering improved regulatory compliance. Contact finish is Tin on both mating and post surfaces, representing a change from the Tin-Lead specification of the obsolete part. This part is available in Tube packaging with 609 units in stock.

1-103735-0 Selection Criteria: This substitute part is recommended for applications requiring gold-plated mating contacts. The gold contact finish (30.0µin thickness) provides enhanced corrosion resistance and contact reliability in demanding environments. The post termination remains Tin-Lead. RoHS status is not applicable for this part. This part is available in Tube packaging with 1105 units in stock.

Both substitute parts maintain full compatibility with the original 1-103639-0 across all mechanical dimensions, electrical ratings, temperature performance, and flammability certifications. Selection between substitutes depends on specific compliance requirements and contact finish performance needs for the target application.

Frequently Asked Questions (FAQ)

Q: Are the substitute parts mechanically compatible with the original 1-103639-0?

A: Yes. Both substitute parts maintain identical mechanical specifications including overall contact length (0.545"), insulation height (0.535"), contact shape (square), and all dimensional parameters. Through-hole mounting and solder termination are identical across all three parts.

Q: What is the difference between the contact finishes on these parts?

A: The main part 1-103639-0 features Tin-Lead contact finish on both mating and post surfaces. Substitute 6-103639-0 uses Tin finish on both surfaces. Substitute 1-103735-0 uses Gold on mating contacts (30.0µin thickness) and Tin-Lead on post surfaces. Contact finish does not affect mechanical fit or electrical current-carrying capacity within the 3A rating.

Q: Can I use 1-103735-0 as a direct replacement for 1-103639-0?

A: Yes, for mechanical and electrical compatibility. The gold-plated mating contacts provide enhanced corrosion resistance compared to the Tin-Lead finish of the original part. This substitution is appropriate for applications where contact reliability and environmental resistance are priorities.

Q: What is the significance of the RoHS compliance difference?

A: The main part 1-103639-0 is RoHS non-compliant due to Tin-Lead contact finish. Substitute 6-103639-0 is ROHS3 compliant, meeting current regulatory requirements for new designs and procurement in regulated markets. Substitute 1-103735-0 has RoHS status listed as not applicable.

Q: Are there packaging differences between these parts?

A: The main part 1-103639-0 is supplied in unspecified packaging with 1067 units in stock. Both substitute parts are supplied in Tube packaging: 6-103639-0 with 609 units and 1-103735-0 with 1105 units in stock.

Q: Do all three parts operate across the same temperature range?

A: Yes. All three parts operate across the identical temperature range of -65°C to 105°C and maintain the same UL94 V-0 flammability rating.

Q: Which substitute should I select for new designs?

A: For new designs, 6-103639-0 is recommended due to active product status and RoHS3 compliance. For applications requiring enhanced contact performance, 1-103735-0 with gold-plated mating contacts is appropriate.
