H2158-06 Equivalent & Substitute Parts

Part Overview

The H2158-06 is a PC Pin Terminal Connector manufactured by Harwin Inc., designed for through-hole mounting applications. This component features a 0.026" (0.67mm) diameter pin with tin-lead contact finish and is terminated via swaging. The part is currently classified as obsolete, necessitating identification of active equivalent alternatives to support ongoing procurement and design requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the H2158-06 is determined by compatibility across the following critical parameters:

• Terminal Type & Style: PC Pin, Single End configuration
• Mounting Method: Through-hole swage termination
• Contact Material & Finish: Brass base with metallic finish
• Board Thickness Compatibility: Mounting hole diameter and flange geometry must accommodate standard PCB thicknesses
• Compliance & Certifications: RoHS3 compliance and REACH status

The H2159-01 qualifies as a manufacturer-recommended substitute. While it features a slightly smaller pin diameter (0.025" vs 0.026") and different dimensional specifications, it maintains functional equivalence through identical terminal type, mounting method, and material composition. Both parts are non-insulated brass PC pins with swage termination and RoHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

The H2159-01 is designated as the manufacturer-recommended substitute for the obsolete H2158-06. Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for new designs and legacy system support.

Selection of H2159-01 requires verification that the smaller mounting hole diameter (0.042" ~ 0.045" vs 0.060" ~ 0.063") and reduced board thickness specification (0.031" vs 0.063") are compatible with the target PCB design. The pin diameter reduction (0.025" vs 0.026") and flange diameter reduction (0.057" vs 0.078") represent minor dimensional changes within typical manufacturing tolerances for PC pin connectors.

The contact finish change from tin-lead to tin reflects current RoHS3 compliance practices and does not affect electrical performance in standard through-hole applications.

Frequently Asked Questions (FAQ)

Q: Can H2159-01 directly replace H2158-06 in existing designs?

A: Direct replacement requires PCB design compatibility verification. The H2159-01 features a smaller mounting hole diameter and is specified for thinner board stock. Existing PCB layouts designed for the H2158-06 mounting hole diameter (0.060" ~ 0.063") may require modification to accommodate the H2159-01 hole diameter (0.042" ~ 0.045").

Q: What is the significance of the pin diameter difference?

A: The pin diameter reduction from 0.026" to 0.025" represents a 0.001" (0.025mm) decrease. This minor dimensional change is within standard PC pin connector manufacturing tolerances and does not affect electrical performance or contact integrity in swage termination applications.

Q: Why does the contact finish differ between these parts?

A: The H2158-06 uses tin-lead finish, while the H2159-01 uses tin finish. This change reflects current RoHS3 compliance requirements. Tin finish provides equivalent electrical and corrosion resistance properties for through-hole PC pin applications.

Q: Are both parts RoHS3 compliant?

A: Yes. Both H2158-06 and H2159-01 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement.

Q: What board thickness should be used with each part?

A: The H2158-06 is specified for 0.063" (1.60mm) board thickness, while the H2159-01 is specified for 0.031" (0.79mm) board thickness. Board thickness selection must align with the mounting hole diameter and flange geometry of the selected component.
