Substitute Part Grouping Explanation

The H3191-01 is identified as the manufacturer-recommended substitute for the H3482-46. Substitution compatibility is determined by the following critical parameters:

Pin Acceptance Range: The H3482-46 accepts pins of 0.016" ~ 0.021" (0.41mm ~ 0.53mm) diameter. The H3191-01 accepts pins of 0.018" ~ 0.020" (0.46mm ~ 0.51mm) diameter. The H3191-01 pin acceptance range falls within the upper portion of the H3482-46 specification, providing functional compatibility for pins within the 0.018" ~ 0.020" range.

Contact Material: Both parts utilize beryllium copper contacts, ensuring equivalent electrical and mechanical performance characteristics.

Operating Temperature Range: Both parts operate across the identical temperature range of -55°C ~ 125°C.

Compliance Standards: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for equivalent substitution.

Termination Difference: The H3482-46 uses surface mount termination, while the H3191-01 uses solder termination. This represents a design change that requires PCB layout modification but does not affect the connector's functional performance with compatible pin diameters.

Engineering Selection Recommendations

The H3191-01 is the active equivalent part for the obsolete H3482-46. Selection of the H3191-01 as a replacement is supported by:

Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying current regulatory requirements for electronic component procurement.

Product Availability: The H3191-01 is actively produced by Harwin Inc. with substantial inventory availability (5579 pcs), ensuring reliable procurement for production and field service applications.

Functional Compatibility: Pin acceptance range, contact material, and operating temperature specifications provide functional equivalence for applications using pins within the 0.018" ~ 0.020" diameter range.

Design Considerations: Implementation of the H3191-01 requires PCB layout modification due to differences in termination method (solder vs. surface mount), overall length (0.193" vs. 0.126"), and socket depth (0.175" vs. 0.110"). These physical differences necessitate design review and validation before production implementation.

Frequently Asked Questions (FAQ)

Q: Can the H3191-01 accept all pin sizes that the H3482-46 accepts?

A: No. The H3191-01 accepts pins of 0.018" ~ 0.020" (0.46mm ~ 0.51mm) diameter, which represents the upper portion of the H3482-46 specification range of 0.016" ~ 0.021" (0.41mm ~ 0.53mm). Pins smaller than 0.018" or larger than 0.020" cannot be used with the H3191-01.

Q: What is the primary difference between these two parts?

A: The H3482-46 uses surface mount termination, while the H3191-01 uses solder termination. Additionally, the H3191-01 is longer (0.193" vs. 0.126") and has greater socket depth (0.175" vs. 0.110"). These differences require PCB design modification for substitution.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the H3482-46 and H3191-01 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement.

Q: What is the insertion force difference between these parts?

A: The H3482-46 specifies a fixed insertion force of 5.00N. The H3191-01 specifies a range of 2.00N ~ 6.00N, which encompasses the H3482-46 specification and provides equivalent performance.

Q: Can I use the H3191-01 as a direct drop-in replacement?

A: No. The H3191-01 requires PCB layout modification due to different termination method, increased overall length, and greater socket depth. Design review and validation are necessary before implementation.

Q: What inventory status should I expect for the H3191-01?

A: The H3191-01 is actively produced by Harwin Inc. with 5579 pcs currently in stock, providing reliable availability for production and field service applications.
