D2922-42 Equivalent & Substitute Parts

Part Overview

The D2922-42 is a 22-position DIP socket manufactured by Harwin Inc., designed for through-hole mounting of dual inline package integrated circuits. This component features gold-plated beryllium copper mating contacts with tin-plated brass posts, operating across the industrial temperature range of -55°C to 125°C. The part is currently active in production with 869 units in stock. Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and design continuity when the primary part becomes unavailable or when alternative specifications better suit specific application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the D2922-42 is determined by the following critical parameters:

• Position Count and Configuration: 22 positions in 2 x 11 arrangement (mandatory match)
• Mating Pitch: 0.100" (2.54mm) standard DIP pitch (mandatory match)
• Contact Finish - Mating: Gold plating required for signal integrity and corrosion resistance
• Contact Material - Mating: Beryllium copper for consistent contact force and durability
• Mounting Type: Through-hole solder termination (mandatory match)
• Operating Temperature Range: -55°C to 125°C (mandatory match)
• Current Rating: 1 A minimum (mandatory match)
• Contact Resistance: 10mOhm maximum (mandatory match)

The substitute part 110-87-322-41-001101 (Preci-Dip) meets all mandatory electrical and mechanical parameters. The primary difference is the row spacing of 0.3" (7.62mm) versus the main part's 0.4" (10.16mm), which represents a mechanical variation that does not affect electrical performance or pin functionality. This variation allows for more compact board layouts while maintaining full electrical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the D2922-42 and 110-87-322-41-001101 are active production parts with identical electrical specifications and performance characteristics. The D2922-42 is RoHS non-compliant, while the Preci-Dip substitute (110-87-322-41-001101) is ROHS3 compliant. For applications subject to RoHS3 regulatory requirements, the Preci-Dip part is the appropriate selection. For legacy systems or applications without RoHS compliance mandates, either part is functionally equivalent. The row spacing difference (0.4" versus 0.3") is a mechanical consideration that affects PCB layout density but does not impact electrical performance or pin compatibility. Inventory availability should be evaluated based on procurement lead times and project schedules.

Frequently Asked Questions (FAQ)

Q: Can the 110-87-322-41-001101 be used as a direct replacement for the D2922-42?

A: Yes, electrically and functionally. Both parts have identical pin counts, mating pitch, contact materials, current ratings, and operating temperature ranges. The row spacing difference (0.3" versus 0.4") is a mechanical variation that requires PCB layout adjustment but does not affect electrical compatibility or signal integrity.

Q: What is the significance of the row spacing difference?

A: Row spacing determines the physical distance between the two rows of pins on the socket. The D2922-42 has 0.4" spacing, while the 110-87-322-41-001101 has 0.3" spacing. This affects the footprint size on the printed circuit board. Designs using the narrower 0.3" spacing allow for more compact layouts. Existing PCB designs must be verified for compatibility with the selected row spacing.

Q: Are there compliance differences between these parts?

A: Yes. The D2922-42 is RoHS non-compliant, while the 110-87-322-41-001101 is ROHS3 compliant. For applications requiring RoHS3 certification or regulatory compliance, the Preci-Dip part is the required selection.

Q: Do both parts have the same contact resistance?

A: Yes. Both parts specify 10mOhm maximum contact resistance, ensuring equivalent electrical performance and signal quality.

Q: What is the difference in termination post length?

A: The D2922-42 has a post length of 0.126" (3.20mm), while the 110-87-322-41-001101 has 0.125" (3.18mm). This 0.001" difference is negligible for through-hole solder applications and does not affect assembly or performance.

Q: Are both parts available in the same packaging?

A: No. The D2922-42 is supplied in tube packaging, while the 110-87-322-41-001101 is supplied in bulk packaging. Packaging selection may affect handling, storage, and procurement quantities.
