Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity Erni 114744 is determined by strict equivalence across the following critical parameters:

Position Configuration: 169 total positions with 125 signal positions and 44 dedicated ground positions must be maintained.

Pitch Specification: 0.079" (2.00mm) center-to-center spacing is a fundamental mechanical requirement for PCB compatibility.

Row Architecture: The 5+2 row configuration defines the physical footprint and connector envelope.

Termination Method: Press-fit termination is the specified connection technology and cannot be altered.

Connector Type: Header with male pins is the required gender and pin configuration.

Mounting Technology: Through-hole mounting on PCB is the specified installation method.

The substitute part 5646531-1 satisfies all these critical parameters and is therefore classified as a direct equivalent.

Frequently Asked Questions (FAQ)

Q: Can the 5646531-1 be used as a direct replacement for the 114744 in existing designs?

A: Yes. The 5646531-1 is mechanically and electrically equivalent to the 114744 across all critical parameters: 169-position configuration, 2mm pitch, 5+2 row architecture, through-hole mounting, and press-fit termination. PCB footprints designed for the 114744 will accommodate the 5646531-1 without modification.

Q: What is the primary reason for substitution?

A: The 114744 is classified as obsolete and is no longer in active production. The 5646531-1 is the active equivalent part from TE Connectivity AMP Connectors, ensuring continued availability and supply chain support.

Q: Are there any packaging differences between the two parts?

A: The 114744 packaging is listed as "-" (not specified). The 5646531-1 is supplied in Bulk packaging. Verify bulk packaging requirements against your procurement specifications.

Q: Does the substitute part meet current regulatory standards?

A: Yes. The 5646531-1 is RoHS Compliant and REACH Unaffected. The original 114744 regulatory status is not documented. If regulatory compliance is a design requirement, the 5646531-1 satisfies current standards.

Q: What is the moisture sensitivity level of the substitute part?

A: The 5646531-1 carries MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.

Q: Are there any electrical performance differences?

A: The 114744 electrical specifications are not documented. The 5646531-1 provides 1.5 A current rating, 500Vrms voltage rating, and -55°C ~ 125°C operating temperature range. These specifications are typical for backplane header connectors in this position class.
