H3484-42R Equivalent & Substitute Parts

Part Overview

The H3484-42R is a pin receptacle connector manufactured by Harwin Inc., designed to accept pin diameters of 0.035" ~ 0.041" (0.89mm ~ 1.05mm) 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 replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the H3484-42R is based on the following critical parameters that must remain consistent:

• Pin diameter acceptance range: 0.035" ~ 0.041" (0.89mm ~ 1.05mm)
• Tail type: No Tail
• Contact material: Beryllium Copper
• Contact finish: Gold
• Operating temperature range: -55°C ~ 125°C
• Insertion force range: 3.00N ~ 9.00N
• RoHS3 compliance

The primary difference between the H3484-42R and its substitute is the termination method. The H3484-42R uses surface mount termination, while the H3185-01 uses solder termination. Both parts maintain electrical and mechanical compatibility through identical pin acceptance specifications, contact materials, and operating parameters. The H3185-01 is an active product with current manufacturing status and established supply chain availability.

Parameter Comparison

Engineering Selection Recommendations

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

• Active product status with established manufacturing and supply chain continuity
• Identical electrical specifications including pin diameter acceptance, contact material, contact finish, and operating temperature range
• Identical mechanical compatibility through matching insertion force parameters
• Full RoHS3 compliance certification
• REACH unaffected status matching the original part

The primary design consideration is the transition from surface mount to solder termination. This change requires PCB layout modification to accommodate solder tail attachment rather than surface mount pads. The H3185-01 includes a mounting hole diameter of 0.086" ~ 0.090" (2.18mm ~ 2.29mm) and flange diameter of 0.125" (3.18mm) to support through-hole solder attachment.

Frequently Asked Questions (FAQ)

Q: Can the H3185-01 be used as a direct replacement for the H3484-42R without PCB modification?

A: No. The H3484-42R uses surface mount termination while the H3185-01 uses solder termination. PCB layout changes are required to accommodate the different attachment method. The H3185-01 requires through-hole mounting with solder attachment, whereas the H3484-42R was designed for surface mount pads.

Q: Are the electrical specifications identical between these parts?

A: Yes. Both parts accept pin diameters of 0.035" ~ 0.041" (0.89mm ~ 1.05mm), use beryllium copper contacts with gold finish, operate across -55°C ~ 125°C, and maintain insertion force specifications of 3.00N ~ 9.00N.

Q: What is the difference in overall length between these parts?

A: The H3484-42R has an overall length of 0.197" (5.00mm), while the H3185-01 measures 0.236" (6.00mm). This difference is due to the solder tail extension required for through-hole mounting.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the H3484-42R and H3185-01 are ROHS3 compliant and REACH unaffected.

Q: What is the moisture sensitivity level difference?

A: The H3484-42R lists moisture sensitivity as not applicable. The H3185-01 is rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage and handling.
