ICA-422-SST Equivalent & Substitute Parts Reference

Part Overview

The ICA-422-SST is a 22-position DIP socket manufactured by Samtec Inc., designed for through-hole mounting applications. This socket features 0.4" (10.16mm) row spacing with gold-plated mating contacts and tin-plated brass posts. The component is classified as Active product status with full RoHS3 compliance. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling direct replacement in circuit board designs without functional degradation.

Substitute Part Grouping Explanation

Substitution eligibility for the ICA-422-SST is determined by strict alignment of the following parameters:

Critical Matching Parameters:

Number of Positions: 22 (2 x 11)
Socket Type: DIP with 0.4" (10.16mm) row spacing
Pitch - Mating: 0.100" (2.54mm)
Pitch - Post: 0.100" (2.54mm)
Contact Finish - Mating: Gold
Contact Material - Mating: Beryllium Copper
Mounting Type: Through Hole
Termination: Solder
Operating Temperature Range: -55°C ~ 125°C
RoHS Status: ROHS3 Compliant

All three substitute parts listed meet these critical parameters. Variations in secondary specifications such as contact finish thickness, post length, current rating, and housing material do not preclude substitution when the primary electrical and mechanical interfaces remain identical.

The part is Active status with ROHS3 compliance and MSL 1. Housing material is PCT/Polyester/Glass Filled. Inventory availability is 1969 units.

22-4518-10 (Aries Electronics)

This substitute meets all critical electrical and mechanical parameters with 3 A current rating and UL94 V-0 flammability rating. The part is Active status with ROHS3 compliance and MSL 1. Housing material is Polyamide (PA46) Nylon 4/6 Glass Filled. Operating temperature range is not specified in available documentation. Packaging is Bulk format. Inventory availability is 717 units.

Frequently Asked Questions (FAQ)

Q: Can the 110-43-422-41-001000 be used as a direct replacement for the ICA-422-SST?

A: Yes. Both parts share identical pin count (22), pitch (0.100"), row spacing (0.4"), contact materials (Beryllium Copper mating, Brass posts), and mounting configuration (Through Hole, Solder termination). Both are ROHS3 compliant and operate across -55°C to 125°C. The higher current rating (3 A vs 1 A) does not prevent substitution.

Q: What is the difference between the Preci-Dip 110-87-422-41-001101 and Mill-Max 110-43-422-41-001000?

A: Both are functionally equivalent to the ICA-422-SST. The Preci-Dip part matches the original contact resistance specification (10mOhm) and current rating (1 A). The Mill-Max part offers higher current capacity (3 A). Housing material composition differs: Preci-Dip uses PCT/Polyester/Glass Filled while Mill-Max uses PCT/Polyester.

Q: Is the Aries 22-4518-10 suitable for applications requiring specified operating temperature range?

A: The Aries part does not provide operating temperature specification in available documentation. For applications where -55°C to 125°C operation is required, the Samtec ICA-422-SST, Mill-Max 110-43-422-41-001000, or Preci-Dip 110-87-422-41-001101 are preferred selections.

Q: Does packaging format affect electrical performance?

A: No. The ICA-422-SST and substitute parts are supplied in either Tube or Bulk packaging. Packaging format does not affect electrical characteristics, mechanical fit, or functional performance. Selection between Tube and Bulk packaging is determined by procurement and inventory management requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The ICA-422-SST and all three substitute parts (110-43-422-41-001000, 110-87-422-41-001101, 22-4518-10) are ROHS3 compliant.
