H8502-46 Equivalent & Substitute Parts

Part Overview

The H8502-46 is a pin receptacle connector manufactured by Harwin Inc., designed for press-fit termination applications. This component accepts pin diameters of 0.024" to 0.033" (0.60mm to 0.85mm) and features a knurled press-fit termination with beryllium copper contacts finished in tin. The H8502-46 is currently classified as obsolete, making identification of active equivalent parts essential for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the H8502-46 is determined by strict alignment of the following critical parameters:

• Accepts Pin Diameter: 0.024" ~ 0.033" (0.60mm ~ 0.85mm)
• Tail Type: No Tail
• Termination Type: Press-Fit, Knurled
• Length - Overall: 0.232" (5.89mm)
• Mounting Hole Diameter: 0.075" ~ 0.077" (1.91mm ~ 1.96mm)
• Flange Diameter: 0.105" (2.67mm)
• Socket Depth: 0.183" (4.65mm)
• Contact Material: Beryllium Copper
• Operating Temperature Range: -55°C ~ 125°C
• Insertion Force: 1.50N ~ 5.01N

The H8502-01 qualifies as a direct substitute based on identical alignment across all mechanical and electrical parameters. Both components share the same base product number (H8502) and are manufactured by Harwin Inc. The primary distinction is product status: H8502-46 is obsolete while H8502-01 is active, and contact finish differs (tin versus gold).

Parameter Comparison

Engineering Selection Recommendations

The H8502-01 is the manufacturer-recommended substitute for the obsolete H8502-46. Both components maintain identical mechanical compatibility and electrical performance specifications. The H8502-01 is currently in active production status with confirmed inventory availability, ensuring supply chain continuity.

Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for current applications. The contact finish difference (tin on H8502-46 versus gold on H8502-01) does not affect mechanical interchangeability or functional performance within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can H8502-01 be used as a direct replacement for H8502-46?

A: Yes. The H8502-01 is mechanically and electrically identical to the H8502-46 across all critical parameters including pin diameter acceptance, termination type, overall dimensions, and operating temperature range.

Q: What is the difference between the tin and gold contact finishes?

A: Both finishes are applied to beryllium copper contacts. The contact finish difference does not affect mechanical press-fit compatibility or electrical performance within the specified operating parameters.

Q: Are both parts RoHS compliant?

A: Yes. Both H8502-46 and H8502-01 are ROHS3 compliant and REACH unaffected.

Q: Why is H8502-46 listed as obsolete?

A: H8502-46 has been discontinued by the manufacturer. H8502-01 is the active equivalent part currently in production.

Q: What packaging is available for H8502-01?

A: H8502-01 is supplied in bulk packaging.
