Key Parameters

Substitute Part Grouping Explanation

Substitution of the H2177-05 is determined by strict equivalence of the following critical parameters:

• Pin diameter: 0.041" (1.04mm)
• Flange diameter: 0.070" (1.77mm)
• Mounting hole diameter range: 0.041" ~ 0.045" (1.04mm ~ 1.14mm)
• Mounting type: Through hole
• Termination method: Swage
• Contact material: Brass
• Contact finish: Gold
• Board thickness: 0.063" (1.60mm)
• Insulation: Non-insulated

The Harwin H2173-05 meets all these criteria and is classified as an active product, making it a direct functional equivalent for the obsolete H2177-05.

Parameter Comparison

Engineering Selection Recommendations

The H2173-05 is the recommended substitute for the obsolete H2177-05. Both components are manufactured by Harwin Inc. and share identical critical electrical and mechanical parameters including pin diameter, flange diameter, mounting hole specifications, and contact material/finish.

The H2173-05 maintains full compliance with ROHS3 and REACH requirements, ensuring regulatory equivalence. The primary difference is overall length: the H2173-05 measures 0.402" (10.20mm) compared to the H2177-05 at 0.355" (9.02mm), representing a 0.047" (1.18mm) increase. This dimensional variance must be evaluated against specific board layout and connector cavity depth requirements in the target application.

The H2173-05 is currently in active production with substantial inventory availability (13,036 pieces), providing supply chain reliability for new designs and production continuity.

Frequently Asked Questions (FAQ)

Q: Can the H2173-05 be used as a direct replacement for H2177-05 in existing designs?

A: The H2173-05 is functionally equivalent in all critical parameters. However, the 0.047" (1.18mm) increase in overall length must be verified against board thickness, connector cavity depth, and PCB layout constraints before implementation.

Q: What are the key differences between these two parts?

A: The primary difference is overall length. The H2177-05 measures 0.355" (9.02mm) overall, while the H2173-05 measures 0.402" (10.20mm). All other specifications including pin diameter, flange diameter, contact material, finish, and termination method are identical.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the H2177-05 and H2173-05 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Why is the H2177-05 obsolete?

A: The H2177-05 is classified as obsolete by Harwin Inc. The H2173-05 serves as the active equivalent product for ongoing supply and new designs.

Q: What is the packaging difference?

A: The H2177-05 was supplied in standard packaging, while the H2173-05 is available in bulk packaging. Bulk packaging is suitable for high-volume production and automated assembly processes.

Q: Are there any electrical performance differences?

A: No. Both components use identical brass contact material with gold plating, swage termination, and non-insulated construction, ensuring equivalent electrical performance in through-hole applications.
