IC-628-SGT DIP Socket 28-Position Equivalent & Substitute Parts

Part Overview

The IC-628-SGT is a 28-position DIP socket manufactured by Samtec Inc., designed for through-hole mounting of dual inline package integrated circuits. This socket features gold-plated beryllium copper mating contacts and phosphor bronze posts, rated for 1 A continuous current with a contact resistance of 10 mOhm. The part is classified as obsolete, making identification of active equivalent alternatives necessary for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IC-628-SGT is determined by strict equivalence across the following critical parameters:

• Position Count & Geometry: 28-position configuration with 2 x 14 arrangement and 0.6" row spacing
• Contact Pitch: 0.100" (2.54mm) mating and post pitch for PCB footprint compatibility
• Mounting & Termination: Through-hole solder termination for identical board integration
• Electrical Performance: 1 A current rating and 10 mOhm contact resistance
• Environmental Compliance: UL94 V-0 flammability rating and ROHS3 compliance
• Operating Temperature: -55°C to 125°C range

The ICA-628-SGG qualifies as a direct substitute based on matching all critical parameters. The primary distinction is product status: IC-628-SGT is obsolete, while ICA-628-SGG is active production. Secondary differences in contact post material (phosphor bronze vs. brass) and post contact finish thickness do not affect functional compatibility within the specified electrical and thermal operating envelope.

Parameter Comparison

Engineering Selection Recommendations

The ICA-628-SGG is the appropriate selection for new designs and production continuity. As an active product from the same manufacturer with identical electrical specifications, mechanical dimensions, and compliance certifications, it provides direct functional equivalence to the obsolete IC-628-SGT.

Both parts maintain ROHS3 compliance and UL94 V-0 flammability certification, ensuring regulatory alignment for applications requiring these standards. The ICA-628-SGG's active production status ensures supply chain availability and long-term support, eliminating obsolescence risk associated with the IC-628-SGT.

Frequently Asked Questions (FAQ)

Q: Can ICA-628-SGG be used as a direct replacement for IC-628-SGT on existing PCBs?

A: Yes. Both parts share identical footprints, pitch specifications (0.100" mating and post), and row spacing (0.6"). No PCB redesign is required.

Q: What is the difference between the contact post materials?

A: IC-628-SGT uses phosphor bronze posts while ICA-628-SGG uses brass posts. Both materials provide equivalent electrical performance and solder joint reliability within the specified 1 A current rating and 10 mOhm contact resistance parameters.

Q: Are there packaging differences between these parts?

A: IC-628-SGT is supplied without specified packaging, while ICA-628-SGG is supplied in tube packaging. This affects handling and storage but does not impact electrical or mechanical compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both IC-628-SGT and ICA-628-SGG are ROHS3 compliant, UL94 V-0 rated, and operate across the identical -55°C to 125°C temperature range.

Q: Why should I transition from IC-628-SGT to ICA-628-SGG?

A: IC-628-SGT is classified as obsolete. ICA-628-SGG is in active production, ensuring continued availability, consistent quality, and manufacturer support for future procurement needs.
