H3482-42 Equivalent & Substitute Parts

Part Overview

The H3482-42 is a pin receptacle connector manufactured by Harwin Inc., designed for 0.016" to 0.021" (0.41mm to 0.53mm) pin diameters with surface mount termination. This component is classified as obsolete, which necessitates identification of active equivalent parts to maintain design continuity and ensure procurement availability for new production runs and field service applications.

Key Parameters

Substitute Part Grouping Explanation

The H3191-01 qualifies as a functional equivalent based on the following critical parameters:

Compatibility Criteria:

• Contact material: Both use beryllium copper with gold finish
• Operating temperature range: Identical (-55°C ~ 125°C)
• Tail type: Both feature no tail configuration
• RoHS compliance: Both meet ROHS3 requirements
• Accepts pin diameter: H3191-01 accepts 0.018" ~ 0.020" (0.46mm ~ 0.51mm), which overlaps the H3482-42 range of 0.016" ~ 0.021" (0.41mm ~ 0.53mm)

Key Difference: The primary distinction is termination method: H3482-42 uses surface mount termination, while H3191-01 uses solder termination. This substitution is valid when the application can accommodate solder termination instead of surface mount.

Parameter Comparison

Engineering Selection Recommendations

The H3191-01 is the active equivalent for the obsolete H3482-42. Selection of this substitute is supported by:

• Active product status ensures ongoing availability and manufacturing support
• ROHS3 compliance maintains regulatory alignment with the original part
• Identical operating temperature range (-55°C ~ 125°C) preserves thermal performance specifications
• Beryllium copper contact material with gold finish maintains electrical and mechanical performance characteristics
• Pin diameter acceptance range (0.018" ~ 0.020") is contained within the original specification (0.016" ~ 0.021"), ensuring compatibility with existing pin designs

The primary design consideration is the change from surface mount to solder termination, which requires PCB layout and assembly process modification.

Frequently Asked Questions (FAQ)

Q: Can H3191-01 directly replace H3482-42 without design changes?

A: Direct replacement requires PCB layout modification. H3482-42 uses surface mount termination while H3191-01 uses solder termination. The footprint, pad configuration, and assembly process differ between these termination methods.

Q: Are the pin acceptance ranges compatible?

A: H3191-01 accepts 0.018" ~ 0.020" (0.46mm ~ 0.51mm) pins, which falls within the H3482-42 specification of 0.016" ~ 0.021" (0.41mm ~ 0.53mm). Pins designed for H3482-42 within the 0.018" to 0.020" range are compatible with H3191-01.

Q: What is the impact of the length difference?

A: H3191-01 has an overall length of 0.193" (4.90mm) compared to H3482-42 at 0.126" (3.20mm). This 0.067" (1.70mm) difference affects board clearance and connector stack height in the assembly.

Q: Are both parts RoHS compliant?

A: Both H3482-42 and H3191-01 meet ROHS3 compliance requirements, maintaining regulatory alignment for applications subject to RoHS directives.

Q: What is the insertion force difference?

A: H3482-42 specifies 5.00N insertion force. H3191-01 specifies a range of 2.00N to 6.00N, which encompasses the original specification and provides equivalent mating force characteristics.
