ICA-320-WGT DIP Socket Equivalent & Substitute Parts

Part Overview

The ICA-320-WGT is a 20-position DIP socket manufactured by Samtec Inc., designed for through-hole mounting applications requiring gold-plated mating contacts. This socket accommodates dual inline package (DIP) integrated circuits with 0.3" row spacing and 0.100" pitch. The product is currently active in production with 909 units in stock.

Equivalent and substitute parts are identified when component availability is limited, supply chain disruptions occur, or design flexibility permits alternative sourcing. Substitute parts must maintain electrical and mechanical compatibility within the specified parameter tolerances for the application.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ICA-320-WGT is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Number of Positions: 20 (2 x 10)
• Row Spacing: 0.3" (7.62mm)
• Pitch - Mating: 0.100" (2.54mm)
• Contact Finish - Mating: Gold
• Mounting Type: Through Hole
• Operating Temperature Range: -55°C to 125°C minimum
• Contact Material - Mating: Beryllium Copper

Allowable Variations:

• Termination method (Solder vs. Wire Wrap)
• Post contact finish composition (Tin vs. Tin-Lead)
• Post contact finish thickness
• Housing material composition (alternative polyester formulations)
• Current rating (if substitute rating meets or exceeds application requirement)

The substitute part 123-93-320-41-001000 from Mill-Max Manufacturing Corp. satisfies all mandatory matching parameters and is therefore classified as a direct electrical and mechanical equivalent.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: ICA-320-WGT (Samtec Inc.)

The ICA-320-WGT is the specified component and should be selected as the primary choice when available. This part carries ROHS3 compliance certification and UL94 V-0 flammability rating, meeting stringent regulatory requirements for consumer and industrial applications.

Substitute Selection: 123-93-320-41-001000 (Mill-Max Manufacturing Corp.)

The 123-93-320-41-001000 is a qualified electrical and mechanical equivalent suitable for substitution when the primary part is unavailable. This substitute maintains all critical mating contact specifications and operating temperature range.

Compliance Considerations:

The substitute part is RoHS non-compliant. Applications subject to RoHS3 regulatory requirements must use the primary ICA-320-WGT part. The substitute is suitable only for applications where RoHS compliance is not mandated.

Termination Method Difference:

The primary part uses solder termination; the substitute uses wire wrap termination. PCB assembly processes must be compatible with the selected termination method. Wire wrap termination requires appropriate post length accommodation (0.510" for the substitute) and wire wrap tooling.

Current Rating:

The substitute part carries a 3 A current rating, exceeding the primary part's 1 A rating. This difference does not restrict substitution for applications requiring 1 A or less.

Frequently Asked Questions (FAQ)

Q: Can the 123-93-320-41-001000 be used as a direct replacement for the ICA-320-WGT in all applications?

A: The 123-93-320-41-001000 is electrically and mechanically compatible for applications not subject to RoHS3 compliance requirements. The different termination method (wire wrap vs. solder) requires PCB assembly process compatibility verification. Applications requiring RoHS3 certification must use the ICA-320-WGT.

Q: What is the significance of the different post contact finish thickness?

A: The substitute part features 200.0µin (5.08µm) post contact finish thickness compared to the primary part's 10.0µin (0.25µm). Both thicknesses provide adequate corrosion protection and electrical performance for through-hole solder or wire wrap connections. The thicker finish on the substitute provides extended service life in high-humidity or corrosive environments.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both the ICA-320-WGT and 123-93-320-41-001000 operate across the -55°C to 125°C temperature range, ensuring thermal compatibility in equivalent applications.

Q: What is the difference between solder and wire wrap termination?

A: Solder termination (ICA-320-WGT) requires reflow or wave soldering during PCB assembly. Wire wrap termination (123-93-320-41-001000) requires wire wrap tooling and is typically used in prototype, repair, or low-volume assembly environments. The assembly method must match the selected part's termination type.

Q: Does the higher current rating of the substitute part affect compatibility?

A: No. The 3 A current rating of the 123-93-320-41-001000 exceeds the 1 A requirement of the ICA-320-WGT. A higher current rating does not restrict substitution and may provide additional design margin for applications approaching the 1 A limit.

Q: Why is RoHS compliance status different between the two parts?

A: The ICA-320-WGT carries ROHS3 compliance certification, meeting European Union Restriction of Hazardous Substances regulations. The 123-93-320-41-001000 is RoHS non-compliant. Applications subject to RoHS3 requirements must use the compliant primary part. Applications without RoHS requirements may use either part.

Q: Can the substitute part be used in medical or aerospace applications?

A: Substitution eligibility for regulated industries (medical, aerospace, automotive) depends on application-specific qualification requirements and certification standards. The provided parameter data does not include industry-specific certifications beyond RoHS and flammability ratings. Application-specific qualification must be verified independently.
