Engineering Selection Recommendations

The TE Connectivity 5-794627-4 is the direct functional equivalent for the obsolete 2-794627-4 connector. Selection of the substitute part is based on the following engineering criteria:

Product Status Consideration: The main part 2-794627-4 carries Obsolete status, indicating discontinued manufacturing and limited availability. The substitute 5-794627-4 maintains Active product status, ensuring ongoing supply chain availability and manufacturer support.

Regulatory Compliance: The substitute part 5-794627-4 achieves ROHS3 compliance, whereas the main part is RoHS non-compliant. This compliance improvement aligns with current regulatory requirements for electronic components in restricted substance directives.

Electrical and Mechanical Equivalence: All critical electrical parameters (voltage rating, operating temperature range, contact configuration) and mechanical parameters (pitch, mounting type, shrouding, termination method) are identical between the two parts. The connector interface, board footprint, and mating characteristics remain unchanged.

Contact Finish Consideration: The substitute part utilizes Tin contact finish in place of Tin-Lead. Both finishes provide equivalent electrical conductivity and solder wettability for the solder termination process. The Tin finish represents a lead-free alternative consistent with RoHS3 compliance.

Packaging Format: The substitute part is supplied in Tape & Reel (TR) packaging, which differs from the standard packaging of the main part. This packaging format is suitable for automated assembly processes and does not affect the connector's functional performance.

Frequently Asked Questions (FAQ)

Q: Can the 5-794627-4 be used as a direct replacement for the 2-794627-4 in existing designs?

A: Yes. The 5-794627-4 is a direct functional equivalent. All electrical and mechanical parameters required for connector interface compatibility are identical, including pitch, number of positions, mounting type, and operating specifications. The connector will mate with the same cable assemblies and occupy the same board footprint.

Q: What is the difference between Tin-Lead and Tin contact finishes?

A: Both finishes provide adequate electrical conductivity and solder wettability for solder termination applications. Tin finish is the lead-free alternative and is associated with RoHS3 compliance. The functional performance in the connector interface is equivalent.

Q: Why is the 2-794627-4 marked as Obsolete?

A: Obsolete status indicates that the manufacturer has discontinued production of this part number. The 5-794627-4 represents the active equivalent, ensuring continued availability and manufacturer support for new designs and production requirements.

Q: Does the Tape & Reel packaging of the 5-794627-4 affect compatibility?

A: No. Tape & Reel packaging is a supply format used for automated assembly processes. It does not alter the connector's electrical or mechanical characteristics. The connector component itself is identical to standard packaging formats.

Q: Are there any temperature or voltage limitations when substituting the 5-794627-4?

A: No. The operating temperature range (-40°C ~ 105°C) and voltage rating (250V) are identical for both parts. The substitute part maintains full specification equivalence across all environmental and electrical parameters.

Q: What is the significance of ROHS3 compliance on the 5-794627-4?

A: ROHS3 compliance indicates that the part meets current Restriction of Hazardous Substances directives, restricting the use of lead and other hazardous materials. This compliance is required for many applications and regulatory jurisdictions. The main part's RoHS non-compliant status may restrict its use in new designs.

Q: Will the 5-794627-4 work with existing cable assemblies designed for the 2-794627-4?

A: Yes. Both parts are part of the same Micro MATE-N-LOK series with identical mating pitch (0.118"), contact configuration, and shrouding design. Existing cable assemblies will mate correctly with the substitute connector.

Q: Is there any difference in current rating between the two parts?

A: No. Both parts specify current rating as "Varies by Wire Gauge," indicating that current capacity is determined by the wire gauge of the mated cable assembly, not the connector itself. The electrical characteristics are equivalent.
