Engineering Selection Recommendations

The TE Connectivity AMP Connectors 5106775-1 is the direct substitute for the obsolete TE Connectivity Erni 104704. Selection of the substitute part is based on the following engineering criteria:

Product Status: The Erni 104704 is classified as obsolete, while the AMP 5106775-1 maintains active product status. Active status ensures continued manufacturing availability, supply chain reliability, and technical support.

Compliance Alignment: Both components maintain RoHS compliance and MSL 1 rating, satisfying environmental and moisture sensitivity requirements. The substitute part carries RoHS compliance certification, meeting regulatory requirements for new designs.

Electrical and Mechanical Equivalence: The substitute part provides identical mechanical interface specifications and electrical performance characteristics. The AMP 5106775-1 specifies 500Vrms voltage rating and 1.5A current rating, parameters not provided for the original part but consistent with backplane connector applications.

Series Transition: The substitute represents a transition from the ERMET series to the Z-PACK series within the TE Connectivity product portfolio. Both series employ identical connector geometry and press-fit termination technology.

Packaging Consideration: The original part is supplied in tray packaging, while the substitute is supplied in tube packaging. This packaging difference does not affect electrical or mechanical performance and reflects standard industry practice for active components.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity AMP 5106775-1 be used as a direct replacement for the Erni 104704?

A: Yes. Both components share identical specifications for connector type, position count, pitch, row configuration, mounting method, termination technology, contact finish, and operating temperature range. Direct substitution is supported without design modification.

Q: What is the significance of the product status difference between the two parts?

A: The Erni 104704 is obsolete, indicating discontinued manufacturing and limited availability. The AMP 5106775-1 is active, ensuring ongoing production, supply chain access, and manufacturer technical support. For new designs and production continuity, the active substitute part is the appropriate selection.

Q: Are there compliance differences between the two parts?

A: Both parts maintain RoHS compliance and MSL 1 rating. The Erni 104704 specifies RoHS3 compliance, while the AMP 5106775-1 specifies RoHS compliance. Both certifications satisfy regulatory requirements for electronic component use.

Q: Does the packaging difference affect connector performance?

A: No. The original part is supplied in tray packaging and the substitute in tube packaging. Packaging format does not affect electrical performance, mechanical interface, or functional characteristics. Packaging selection reflects standard industry practice for component distribution.

Q: What electrical specifications should be considered for application design?

A: The substitute part specifies 500Vrms voltage rating and 1.5A current rating. These specifications define the maximum electrical operating conditions for the connector. Application designs must ensure operating voltage and current remain within these limits.

Q: Are the press-fit termination requirements identical between the two parts?

A: Yes. Both components employ press-fit termination technology with identical mechanical interface specifications. PCB design, hole sizing, and press-fit insertion procedures remain unchanged between the original and substitute parts.

Q: What is the temperature operating range for both connectors?

A: Both the Erni 104704 and AMP 5106775-1 operate across -55°C to 125°C. This temperature range applies to all electrical and mechanical performance specifications.
