Substitute Part Grouping Explanation

Substitution of the TE Connectivity 1375792-1 is based on strict equivalence across all provided electrical and mechanical parameters. The substitute part 1375792-3 qualifies as a direct equivalent because it maintains identical specifications in the following critical areas:

Connector Configuration: Both parts are non-stackthrough, keyed PC/104 connectors with 104 positions (102 loaded) and 4-row configuration.

Physical Specifications: Pitch (0.100"/2.54mm), mounting type (through hole), and termination method (press-fit) are identical.

Contact Properties: Gold plating at 15.0µin (0.38µm) thickness and black color are maintained.

Environmental Ratings: UL94 V-0 flammability rating and operating temperature range (-55°C ~ 105°C) are equivalent.

Mechanical Features: Four screwlocks for retention are present on both parts.

The primary distinction between the main part and substitute is product status and compliance: 1375792-1 is obsolete with RoHS non-compliant status, while 1375792-3 is active with RoHS compliant certification.

Parameter Comparison

Engineering Selection Recommendations

For New Designs: Use TE Connectivity 1375792-3. This part is active in production and carries RoHS compliant certification, meeting current regulatory requirements for electronic component procurement. The active product status ensures long-term availability and supply chain stability.

For Existing Inventory Management: The 1375792-1 remains functionally equivalent for applications where RoHS compliance is not mandated. However, transition planning to 1375792-3 is recommended to align with modern compliance standards and ensure future component availability.

Compliance Considerations: The shift from RoHS non-compliant (1375792-1) to RoHS compliant (1375792-3) reflects current environmental and regulatory standards. Organizations operating under RoHS directives must use 1375792-3 for new production.

Supply Chain: With 926 pieces of 1375792-3 in stock compared to 673 pieces of 1375792-1, the substitute part offers improved availability for procurement planning.

Frequently Asked Questions (FAQ)

Q: Are 1375792-1 and 1375792-3 electrically and mechanically interchangeable?

A: Yes. Both connectors are identical in electrical and mechanical specifications, including connector type, position count, pitch, mounting method, termination type, contact finish, and operating temperature range. They are direct substitutes at the functional level.

Q: What is the primary reason to transition from 1375792-1 to 1375792-3?

A: The 1375792-1 is obsolete and RoHS non-compliant, while 1375792-3 is an active product with RoHS compliant certification. For new designs and production requiring regulatory compliance, 1375792-3 is the appropriate selection.

Q: Can I use 1375792-1 in applications where RoHS compliance is not required?
