Harwin D95022-42 Equivalent & Substitute Parts

Part Overview

The Harwin D95022-42 is a 22-position DIP socket with 0.3" row spacing, designed for through-hole mounting of dual inline package integrated circuits. The socket features gold-plated mating contacts and tin-plated brass posts for reliable solder termination. This part is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the D95022-42 is constrained by the following critical parameters that must remain consistent:

• Pitch - Mating: 0.100" (2.54mm) — determines compatibility with standard DIP component leads
• Contact Finish - Mating: Gold — ensures equivalent contact reliability and corrosion resistance
• Mounting Type: Through Hole — maintains PCB assembly compatibility
• Operating Temperature Range: -55°C to 125°C — defines thermal performance envelope
• Current Rating: 1 A — establishes electrical capacity
• Contact Resistance: 10 mOhm — ensures signal integrity

The D95022-42 is a 22-position socket. Substitute parts must accommodate the same pin count and row spacing to maintain direct PCB compatibility. The Harwin D95028-42 differs in position count (28 positions) and row spacing (0.6" versus 0.3"), making it unsuitable as a direct substitute for the D95022-42 in existing designs.

Parameter Comparison

Engineering Selection Recommendations

The D95022-42 is obsolete and no longer in active production. While the D95028-42 shares identical electrical and thermal specifications, it is not a direct substitute due to fundamental mechanical incompatibility: the D95028-42 accommodates 28 positions with 0.6" row spacing, whereas the D95022-42 requires 22 positions with 0.3" row spacing. These dimensional differences prevent direct PCB mounting without redesign.

For applications requiring the D95022-42, direct substitution is not available within the provided part list. Procurement should focus on locating remaining inventory of the original D95022-42 or initiating a design revision to accommodate an alternative socket architecture. The D95028-42 is suitable only for new designs requiring a 28-position DIP socket with equivalent electrical and compliance characteristics.

Frequently Asked Questions (FAQ)

Q: Can the D95028-42 replace the D95022-42 in an existing design?

A: No. The D95028-42 has 28 positions with 0.6" row spacing, while the D95022-42 has 22 positions with 0.3" row spacing. These differences prevent direct PCB mounting compatibility.

Q: What makes these sockets functionally different despite similar electrical ratings?

A: Position count and row spacing are mechanical parameters that determine physical footprint and PCB layout compatibility. Electrical ratings alone do not determine substitutability for sockets.

Q: Is the D95028-42 suitable for new designs if I need a 22-position socket?

A: No. If your design requires a 22-position socket, the D95028-42 is not appropriate. Select a socket with matching position count and row spacing specifications.

Q: What compliance certifications apply to both parts?

A: Both the D95022-42 and D95028-42 are ROHS3 compliant, UL94 V-0 rated, and REACH unaffected. Both carry MSL 1 (unlimited) moisture sensitivity classification.

Q: Why is the D95022-42 listed as obsolete?

A: Obsolete status indicates the part is no longer in active production. Existing inventory may be available through authorized distributors, but long-term availability is not guaranteed.
