H3484-42 Equivalent & Substitute Parts

Part Overview

The H3484-42 is a pin receptacle connector manufactured by Harwin Inc., designed to accept pin diameters of 0.035" ~ 0.041" (0.89mm ~ 1.05mm) with no tail configuration and 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 replacements.

Key Parameters

Substitute Part Grouping Explanation

The H3185-01 qualifies as a direct substitute for the H3484-42 based on the following critical electrical and mechanical parameters:

Matching Parameters:

• Accepts Pin Diameter: 0.035" ~ 0.041" (0.89mm ~ 1.05mm) — identical specification
• Contact Material: Beryllium Copper — identical material composition
• Contact Finish: Gold — identical surface treatment
• Operating Temperature Range: -55°C ~ 125°C — identical thermal operating window
• Insertion Force: 3.00N ~ 9.00N — identical engagement force specification
• Tail Type: No Tail — identical configuration
• RoHS Status: ROHS3 Compliant — equivalent regulatory compliance

Functional Difference: The primary distinction is termination method: H3484-42 uses surface mount termination, while H3185-01 uses solder termination. This difference requires board-level design consideration but does not affect the core receptacle functionality or pin acceptance criteria.

Parameter Comparison

Engineering Selection Recommendations

The H3185-01 is the manufacturer-recommended substitute for the obsolete H3484-42. Selection of H3185-01 is supported by:

• Active product status ensuring long-term availability and supply chain continuity
• Identical electrical specifications for pin acceptance and contact engagement
• Equivalent thermal and compliance certifications (ROHS3, REACH Unaffected)
• Same contact material and finish specifications guaranteeing electrical performance parity

The transition from surface mount to solder termination requires verification of board layout compatibility and assembly process alignment. No additional electrical or mechanical qualification is necessary when pin diameter, contact material, and operating temperature specifications remain unchanged.

Frequently Asked Questions (FAQ)

Q: Can H3185-01 directly replace H3484-42 in existing designs?

A: H3185-01 accepts the same pin diameter range (0.035" ~ 0.041") and maintains identical contact specifications. The primary design consideration is termination method: H3484-42 uses surface mount attachment while H3185-01 uses solder termination. Board layout and assembly process must accommodate this difference.

Q: Are the electrical performance characteristics identical?

A: Yes. Both parts use beryllium copper contacts with gold finish, operate across -55°C ~ 125°C, and specify 3.00N ~ 9.00N insertion force. Electrical performance is equivalent.

Q: What is the significance of the different overall lengths?

A: H3484-42 measures 0.197" (5.00mm) while H3185-01 measures 0.236" (6.00mm). This 0.039" (1.00mm) difference reflects the different termination methods and does not affect receptacle function. Board clearance and component spacing must be verified during design transition.

Q: Are both parts RoHS compliant?

A: Yes. Both H3484-42 and H3185-01 are ROHS3 Compliant and REACH Unaffected, meeting current regulatory requirements.

Q: Why is H3484-42 obsolete?

A: H3484-42 is classified as obsolete by the manufacturer. H3185-01 represents the active equivalent in the Harwin product line, ensuring continued availability for new designs and production requirements.
