Substitute Part Grouping Explanation

Substitution of the TE Connectivity Erni 923340 is determined by strict equivalence across the following critical parameters:

Position Count and Configuration: The substitute must provide 154 positions with the identical 110 + 44 ground pin distribution.

Pitch and Row Configuration: The 2.00mm pitch and 5 + 2 row arrangement must be maintained to ensure PCB footprint compatibility.

Connector Type and Termination: Male pin headers with press-fit termination are required to match the original mounting and assembly methodology.

Mounting and Temperature Range: Through-hole mounting capability and -55°C to 125°C operating temperature range must be preserved.

Compliance Standards: RoHS compliance and ECCN classification (EAR99) establish the regulatory framework for substitution eligibility.

The TE Connectivity AMP Connectors part number 6345112-1 satisfies all these criteria as the manufacturer-recommended substitute.

Product Status Transition: The 6345112-1 maintains active production status, ensuring long-term availability and supply chain continuity compared to the obsolete 923340.

Regulatory Compliance: Both components satisfy RoHS compliance requirements and maintain EAR99 ECCN classification, confirming regulatory equivalence for international distribution.

Electrical and Mechanical Specifications: Complete parameter alignment across connector type, position count, pitch, row configuration, mounting method, and termination technology establishes direct interchangeability at the PCB assembly level.

Temperature Performance: Identical operating temperature range (-55°C to 125°C) ensures thermal performance equivalence across industrial applications.

Packaging Consideration: The 6345112-1 is supplied in tube packaging, which may differ from the original packaging format but does not affect functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 6345112-1 be used as a direct replacement for the 923340 without PCB redesign?

A: Yes. The 6345112-1 maintains identical pitch (2.00mm), position count (154), row configuration (5 + 2), and mounting type (through-hole press-fit), ensuring direct PCB footprint compatibility without layout modifications.

Q: What is the primary reason for substituting the 923340?

A: The 923340 is classified as obsolete. The 6345112-1 is an active product with ongoing manufacturing support, ensuring component availability for production and field replacement applications.

Q: Are there differences in contact finish between these parts?

A: The 923340 specifies gold contact finish. The 6345112-1 contact finish specification is not provided in the available documentation. Contact finish compatibility should be evaluated based on application-specific requirements.

Q: Does the 6345112-1 include additional features?

A: The 6345112-1 includes an alignment strip feature, which provides enhanced assembly guidance during PCB mounting. The 923340 is specified as shielded. Feature differences do not affect electrical or mechanical interchangeability.

Q: Are both parts RoHS compliant?

A: Yes. The 923340 is ROHS3 compliant, and the 6345112-1 is RoHS compliant, confirming regulatory equivalence for applications requiring lead-free construction.

Q: What is the current rating of the 6345112-1?

A: The 6345112-1 is rated for 1.5 A per contact at 500Vrms. The 923340 does not provide voltage or current rating specifications in the available documentation.

Q: Is the tube packaging of the 6345112-1 compatible with existing assembly processes?

A: Tube packaging is standard for high-position-count connectors and is compatible with automated and manual assembly processes. Packaging format does not affect component functionality or PCB mounting.
