ICA-320-SGG DIP Socket 20-Position Equivalent & Substitute Parts

Part Overview

The ICA-320-SGG is a 20-position DIP socket manufactured by Samtec Inc., designed for through-hole mounting of dual inline package integrated circuits. This connector features gold-plated beryllium copper mating contacts with 0.3" (7.62mm) row spacing and 0.100" (2.54mm) pitch. The part is active in production status with ROHS3 compliance and unlimited moisture sensitivity rating.

Equivalent and substitute parts are identified based on matching core electrical and mechanical parameters: 20-position DIP configuration, 0.3" row spacing, 0.100" pitch, through-hole solder termination, and compatible operating temperature range of -55°C to 125°C.

Substitute Part Grouping Explanation

Substitute parts are classified into two categories based on electrical and mechanical compatibility with the ICA-320-SGG:

Direct Substitutes maintain all critical parameters including mating contact finish (gold), post contact finish (gold), current rating (1 A), and contact resistance (10mOhm). These parts are functionally equivalent for applications requiring identical electrical characteristics.

Similar Substitutes share the core mechanical configuration (20-position DIP, 0.3" row spacing, 0.100" pitch, through-hole termination, -55°C to 125°C operating range) but differ in one or more of the following parameters:

Mating contact finish (tin instead of gold)
Post contact finish (tin or tin-lead instead of gold)
Current rating (3 A instead of 1 A)
Contact resistance (not specified)
Housing material composition
Flammability rating
RoHS compliance status

These variations allow selection based on specific application requirements while maintaining mechanical and thermal compatibility.

Engineering Selection Recommendations

For ROHS3-compliant applications: Select from 110-13-320-41-001000, 110-83-320-41-001101, 110-13-320-41-801000, 110-41-320-41-001000, 110-43-320-41-001000, 110-43-320-41-801000, or 110-44-320-41-001000. All maintain active product status and meet regulatory requirements.

For applications requiring gold post finish matching the ICA-320-SGG: 110-13-320-41-001000 and 110-13-320-41-801000 provide direct electrical equivalence with higher current rating capability (3 A vs. 1 A).

For applications with tin post finish acceptable: 110-83-320-41-001101, 110-41-320-41-001000, 110-43-320-41-001000, and 110-43-320-41-801000 are ROHS3-compliant alternatives with increased current capacity.

For tin-lead post finish applications without RoHS compliance requirement: 110-91-320-41-001000, 110-93-320-41-001000, and 110-93-320-41-605000 are available, though these parts carry RoHS non-compliant status.

For tin mating contact finish: 110-44-320-41-001000 is the only option with both mating and post contacts finished in tin, suitable for applications where gold contact finish is not required.

Frequently Asked Questions (FAQ)

Q: Can 110-13-320-41-001000 directly replace ICA-320-SGG in all applications?

A: 110-13-320-41-001000 shares identical mechanical configuration and gold mating contact finish. The primary difference is higher current rating (3 A vs. 1 A) and unspecified contact resistance. For applications operating at or below 1 A with 10mOhm contact resistance requirements, electrical performance is compatible. Verify post contact finish gold plating thickness (10.0µin vs. 30.0µin) meets application requirements.

Q: What is the significance of the decoupling capacitor feature in 110-13-320-41-801000 and 110-43-320-41-801000?

A: The decoupling capacitor feature indicates integrated capacitive elements within the socket housing. This affects mechanical fit and electrical characteristics. Confirm PCB layout compatibility before substitution.

Q: Are tin post finish sockets electrically equivalent to gold post finish sockets?

A: Tin and gold post finishes differ in contact resistance, corrosion resistance, and solderability characteristics. Both are through-hole solder termination compatible. Selection depends on application environmental conditions and solder process specifications.

Q: Why do some substitute parts show no contact resistance specification?

A: Contact resistance data is not provided in the manufacturer specifications for certain parts. This does not indicate inferior performance but reflects different specification documentation practices. Contact the manufacturer for detailed contact resistance data if this parameter is critical.

Q: Can RoHS non-compliant parts (110-91, 110-93 series) be used in new designs?

A: RoHS non-compliant parts contain tin-lead solder finish and are restricted in many regulated markets and applications. Use only in legacy system repairs or applications explicitly exempted from RoHS requirements.

Q: What packaging differences exist between substitute options?

A: ICA-320-SGG and most Mill-Max substitutes are supplied in tube packaging. 110-83-320-41-001101 (Preci-Dip) is supplied in bulk packaging. Confirm packaging compatibility with assembly process requirements.
