AR22-HZW/T 22-Position DIP Socket Equivalent & Substitute Parts

Part Overview

The AR22-HZW/T is a 22-position DIP socket manufactured by Assmann WSW Components, designed for through-hole IC mounting applications. This component features gold-plated mating contacts, beryllium copper construction, and wire wrap termination with 0.4" row spacing. The part is currently classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing production support and legacy system maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AR22-HZW/T is determined by strict equivalence across the following critical parameters:

• Position Count & Configuration: 22 positions in 2 x 11 DIP arrangement
• Row Spacing: 0.4" (10.16mm) standard DIP spacing
• Mating Pitch: 0.100" (2.54mm) contact spacing
• Mating Contact Finish: Gold plating for corrosion resistance and signal integrity
• Mounting Technology: Through-hole wire wrap termination
• Current Capacity: 3 A minimum rating
• Operating Temperature: Minimum -40°C to 105°C range

The two substitute parts listed below meet all these core electrical and mechanical requirements while offering improved product status and compliance profiles.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts provide direct functional equivalence to the AR22-HZW/T across all critical electrical and mechanical parameters. Selection between alternatives should be based on the following factors:

123-43-422-41-001000 (Mill-Max Manufacturing Corp.)

• Active product status with ongoing manufacturer support
• ROHS3 compliant, meeting current regulatory requirements
• Extended operating temperature range (-55°C ~ 125°C) provides thermal margin beyond the original specification
• Termination post length of 0.510" (12.95mm) accommodates standard wire wrap board designs
• Packaging in tube format supports controlled component handling

22-4508-20 (Aries Electronics)

• Active product status with established supply chain
• ROHS3 compliant for regulatory alignment
• Operating temperature range (-55°C ~ 105°C) maintains compatibility with original specification ceiling
• Termination post length of 0.360" (9.14mm) suits compact board layouts
• Bulk packaging format available for high-volume applications
• UL94 V-0 flammability rating documented

Both parts carry identical electrical ratings, contact materials, and termination specifications. The choice between them depends on specific board design requirements, particularly termination post length and packaging format preferences.

Frequently Asked Questions (FAQ)

Q: Can the 123-43-422-41-001000 or 22-4508-20 be used as direct replacements for the AR22-HZW/T?

A: Yes. Both substitute parts meet all critical substitution parameters: 22-position DIP configuration, 0.4" row spacing, 0.100" mating pitch, gold-plated beryllium copper mating contacts, wire wrap termination, and 3 A current rating. Physical and electrical compatibility is established.

Q: What is the significance of the different termination post lengths?

A: The Mill-Max part features 0.510" (12.95mm) posts, while the Aries part features 0.360" (9.14mm) posts. Post length affects wire wrap board hole depth requirements and component standoff height. Verify your PCB design accommodates the selected post length before procurement.

Q: Why are the substitute parts RoHS3 compliant while the original is not?

A: The AR22-HZW/T is an obsolete component manufactured under earlier regulatory frameworks. The active substitute parts incorporate RoHS3 compliance, reflecting current environmental and material restriction standards. This compliance status is advantageous for new designs and systems subject to modern procurement requirements.

Q: Are there differences in contact material between the mating and post sides?

A: Yes. All three parts use beryllium copper for mating contacts (gold-plated) and tin-plated posts. The Mill-Max substitute uses brass alloy posts, while the Aries substitute uses brass posts. These materials are functionally equivalent for wire wrap applications and maintain the specified contact resistance and current-carrying capacity.

Q: What is the impact of the extended temperature range in the Mill-Max substitute?

A: The Mill-Max 123-43-422-41-001000 operates from -55°C to 125°C, compared to the original -40°C to 105°C range. This extended range provides additional thermal margin and may be beneficial in applications subject to extreme environmental conditions. However, it does not alter electrical performance within the original specification range.

Q: How do packaging formats affect component selection?

A: The Mill-Max part is supplied in tube packaging, while the Aries part is supplied in bulk format. Tube packaging provides individual component protection and controlled handling, suitable for precision assembly environments. Bulk packaging is typical for high-volume manufacturing. Select based on your assembly process requirements and inventory management practices.
