H2079-01 Equivalent & Substitute Parts

Part Overview

The H2079-01 is a Terminal Turret Connector manufactured by Harwin Inc., classified as a single-end, hollow turret terminal with tin contact finish. This component is designed for through-hole mounting applications with swage termination. The part is currently listed as obsolete, which necessitates identification of functionally equivalent alternatives for ongoing design and procurement requirements. The substitute part H9023-01 provides comparable electrical and mechanical functionality for applications requiring turret terminal connectivity.

Key Parameters

Substitute Part Grouping Explanation

The H9023-01 qualifies as a manufacturer-recommended substitute for the H2079-01 based on the following alignment of critical parameters:

Common Electrical & Material Properties:

• Both parts utilize brass alloy contact material with tin finish
• Both are non-insulated single-end turret terminals
• Both employ swage termination methodology
• Both maintain ROHS3 compliance and MSL 1 rating

Mechanical Compatibility Considerations: The H9023-01 introduces dimensional variations in length above board (0.156" vs. 0.136"), flange diameter (0.072" vs. 0.156"), and mounting hole diameter (0.050"–0.054" vs. 0.095"–0.099"). These differences require board-level design verification to ensure mechanical fit within existing PCB mounting patterns and clearance requirements.

Parameter Comparison

Engineering Selection Recommendations

The H9023-01 is the manufacturer-designated substitute for the obsolete H2079-01. Both parts maintain equivalent regulatory compliance (ROHS3, MSL 1) and share identical contact material, finish, and termination methodology.

Selection of H9023-01 requires verification of mechanical compatibility with existing PCB designs. The substitute part features reduced mounting hole diameter (0.050"–0.054" vs. 0.095"–0.099"), smaller flange diameter (0.072" vs. 0.156"), and compatibility with thinner board stock (0.063" vs. 0.094"). These dimensional changes necessitate PCB layout review to confirm mounting hole sizing, clearance, and board thickness specifications align with the substitute component.

The active product status of H9023-01 ensures ongoing availability and supply chain continuity compared to the obsolete H2079-01.

Frequently Asked Questions (FAQ)

Q: Can H9023-01 directly replace H2079-01 in existing designs?

A: Electrical substitution is valid based on identical contact material, finish, and termination method. Mechanical substitution requires PCB design verification due to dimensional differences in mounting hole diameter, flange diameter, and board thickness requirements.

Q: What are the critical dimensional differences between these parts?

A: The H9023-01 features a smaller mounting hole diameter (0.050"–0.054" vs. 0.095"–0.099"), reduced flange diameter (0.072" vs. 0.156"), and is designed for thinner board stock (0.063" vs. 0.094"). The above-board length is also increased (0.156" vs. 0.136").

Q: Are both parts RoHS and MSL compliant?

A: Yes. Both H2079-01 and H9023-01 are ROHS3 compliant with MSL 1 (Unlimited) rating, ensuring equivalent environmental and moisture sensitivity performance.

Q: Why is H2079-01 listed as obsolete?

A: H2079-01 is no longer in active production. H9023-01 is the manufacturer-recommended active alternative that provides equivalent electrical functionality for new designs and ongoing applications.

Q: What packaging is available for H9023-01?

A: H9023-01 is supplied in bulk packaging, with 2626 pieces currently in stock.
