ICO-632-SGT Equivalent & Substitute Parts

Part Overview

The ICO-632-SGT is a 32-position DIP socket manufactured by Samtec Inc., designed for through-hole mounting applications. This socket features a 0.6" row spacing with gold-plated mating contacts and tin-plated brass posts. The product is currently active and widely used in applications requiring reliable IC interconnection with standard DIP package compatibility. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, ensuring functional interchangeability in circuit designs.

Substitute Part Grouping Explanation

The ICO-632-SGT qualifies for substitution with the 110-93-632-41-001000 based on the following critical parameters:

Mechanical Compatibility: Both parts maintain identical 32-position DIP configuration with 0.6" row spacing and 0.100" pitch for mating and post contacts
Electrical Interface: Both feature gold-plated beryllium copper mating contacts with identical contact finish thickness (30.0µin)
Mounting and Termination: Both are through-hole solder-terminated sockets with identical termination post length (0.125")
Operating Environment: Both support the same temperature range (-55°C ~ 125°C) and moisture sensitivity level (MSL 1)
Package Category: Both are DIP sockets for IC interconnection applications

Differences in post contact finish material (tin vs. tin-lead), housing material composition, current rating, and RoHS compliance status do not prevent functional substitution when electrical and mechanical interface requirements are met.

Engineering Selection Recommendations

Primary Selection (ICO-632-SGT): Use when RoHS3 compliance is required for the end application. This part meets current environmental regulations and is suitable for applications with regulatory compliance mandates.

Substitute Selection (110-93-632-41-001000): Use when RoHS compliance is not a requirement and higher current rating capacity (3 A vs. 1 A) is beneficial. This part provides equivalent mechanical and electrical interface compatibility with enhanced current handling capability. The tin-lead post finish and thicker post contact plating (200.0µin) may provide different soldering characteristics compared to the tin-plated original.

Both parts maintain active product status and identical mechanical interface specifications, ensuring direct substitution capability in DIP socket applications where the specified electrical and environmental parameters are met.

Frequently Asked Questions (FAQ)

Q: Can the 110-93-632-41-001000 be used as a direct replacement for the ICO-632-SGT in all applications?

A: Yes, for applications where RoHS compliance is not mandated. Both parts share identical mechanical dimensions, pin configuration, pitch specifications, and mating contact materials. The primary differences are post contact finish composition and current rating capacity.

Q: What is the significance of the different post contact finishes (tin vs. tin-lead)?

A: The post contact finish affects soldering characteristics and long-term reliability in specific environmental conditions. The ICO-632-SGT uses tin plating (10.0µin), while the 110-93-632-41-001000 uses tin-lead plating (200.0µin). Selection depends on soldering process compatibility and end-use environmental requirements.

Q: Does the higher current rating of the 110-93-632-41-001000 (3 A vs. 1 A) affect compatibility?

A: No. Higher current rating indicates greater capacity and does not prevent substitution. The substitute part can handle the same or greater electrical loads as the original specification.

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

A: Yes. Both the ICO-632-SGT and 110-93-632-41-001000 operate across -55°C to 125°C, ensuring thermal compatibility in equivalent applications.

Q: What packaging format is used for both parts?

A: Both parts are supplied in tube packaging, maintaining consistent handling and storage requirements.
