H3492-46 Equivalent & Substitute Parts

Part Overview

The H3492-46 is a pin receptacle connector manufactured by Harwin Inc., designed for PCB socket applications. This component accepts pin diameters of 0.079" to 0.091" (2.00mm to 2.30mm) with solder termination and no tail configuration. The part is classified as obsolete, which necessitates identification of active equivalent alternatives to maintain design continuity and ensure supply chain availability for new production and repair applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the H3492-46 is determined by strict equivalence across the following critical parameters:

• Accepts Pin Diameter: 0.079" ~ 0.091" (2.00mm ~ 2.30mm)
• Tail Type: No Tail
• Termination: Solder
• Length - Overall: 0.315" (8.00mm)
• Mounting Hole Diameter: 0.158" ~ 0.162" (4.01mm ~ 4.12mm)
• Flange Diameter: 0.187" (4.75mm)
• Socket Depth: 0.161" (4.09mm)
• Contact Material: Beryllium Copper
• Operating Temperature: -55°C ~ 125°C
• Insertion Force: 3.00N ~ 6.00N

The H3492-01 qualifies as a direct substitute based on identical mechanical and electrical specifications across all critical parameters. The primary distinction is the contact finish specification and product status transition from obsolete to active.

Parameter Comparison

Engineering Selection Recommendations

The H3492-01 is the direct substitute for the obsolete H3492-46. Both parts maintain identical mechanical dimensions, electrical performance characteristics, and operating parameters. The transition from tin to gold contact finish in the H3492-01 represents an enhancement in contact reliability and corrosion resistance while maintaining full mechanical and electrical compatibility.

Both parts satisfy ROHS3 compliance and carry unlimited moisture sensitivity classification, ensuring regulatory and environmental compatibility across applications. The H3492-01 is actively manufactured and stocked, providing supply chain continuity for designs currently using or transitioning from the H3492-46.

Frequently Asked Questions (FAQ)

Q: Can H3492-01 be used as a direct replacement for H3492-46 in existing designs?

A: Yes. The H3492-01 maintains identical pin acceptance diameter (0.079" ~ 0.091"), mounting hole diameter (0.158" ~ 0.162"), flange diameter (0.187"), socket depth (0.161"), and insertion force (3.00N ~ 6.00N). All mechanical and electrical parameters are equivalent.

Q: What is the difference between the tin finish on H3492-46 and the gold finish on H3492-01?

A: The contact finish differs between the two parts. H3492-46 uses tin plating (94.5µin thickness), while H3492-01 uses gold plating (3.94µin thickness). Both finishes are compatible with solder termination and provide electrical conductivity. Gold finish offers enhanced corrosion resistance in high-humidity or corrosive environments.

Q: Are both parts RoHS compliant?

A: Yes. Both H3492-46 and H3492-01 are ROHS3 compliant and carry REACH Unaffected status, meeting current environmental and regulatory requirements.

Q: What is the packaging difference between these parts?

A: H3492-46 packaging is listed as unspecified in available documentation. H3492-01 is supplied in bulk packaging, which is standard for production quantities.

Q: Why is H3492-46 classified as obsolete?

A: H3492-46 is no longer in active production. The H3492-01 represents the current active equivalent from Harwin Inc. for this connector type and should be specified for new designs and procurement.
