Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the H2155-01 is determined by the following critical parameters:

• Terminal Type & Style: PC Pin, Double End configuration
• Contact Material & Finish: Brass with Tin plating
• Mounting Method: Through Hole with Swage termination
• Board Compatibility: 0.063" (1.60mm) board thickness
• Regulatory Compliance: ROHS3 Compliant, REACH Unaffected status

The H2105-01 qualifies as a manufacturer-recommended substitute. While the pin diameter increases from 0.031" to 0.032" and overall dimensions differ, both parts maintain identical terminal type, contact material, finish, mounting method, and board thickness specifications. The mounting hole diameter range (0.052" ~ 0.056" for H2105-01 versus 0.050" ~ 0.054" for H2155-01) represents a compatible tolerance overlap suitable for through-hole applications.

Parameter Comparison

Engineering Selection Recommendations

The H2105-01 is the manufacturer-recommended substitute for the obsolete H2155-01. Both components maintain ROHS3 compliance and REACH Unaffected status, ensuring regulatory continuity. The H2105-01 carries Active product status, providing assured long-term availability and supply chain stability compared to the Obsolete H2155-01.

Dimensional variations between the parts require board-level design verification. The H2105-01 features a shorter overall length (0.375" versus 0.719") and reduced above-flange length (0.156" versus 0.480"), which may impact circuit board layout and connector interface geometry. The pin diameter increase from 0.031" to 0.032" and mounting hole diameter shift must be evaluated against PCB hole tolerances and connector receptacle specifications.

Frequently Asked Questions (FAQ)

Q: Can H2105-01 directly replace H2155-01 in existing designs?

A: Direct replacement requires design verification. While both parts share identical terminal type, contact material, finish, and board thickness specifications, dimensional differences—particularly overall length and pin diameter—necessitate confirmation of PCB hole sizing and connector compatibility.

Q: What are the key differences between H2155-01 and H2105-01?

A: The primary differences are pin diameter (0.031" versus 0.032"), overall length (0.719" versus 0.375"), above-flange length (0.480" versus 0.156"), and product status (Obsolete versus Active). Mounting hole diameter ranges differ slightly but overlap within acceptable tolerances.

Q: Are both parts compliant with current regulatory requirements?

A: Yes. Both H2155-01 and H2105-01 are ROHS3 Compliant and REACH Unaffected, meeting current regulatory standards for electronic components.

Q: Why is H2155-01 classified as Obsolete?

A: Obsolete status indicates the part is no longer in active production. The H2105-01 serves as the active alternative for new designs and ongoing procurement.

Q: What packaging is available for H2105-01?

A: H2105-01 is supplied in Bulk packaging, compared to the standard packaging designation for H2155-01.
