ICA-628-WGT DIP Socket Equivalent & Substitute Parts

Part Overview

The ICA-628-WGT is a 28-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 0.6" row spacing and 0.100" pitch. The part is currently in active production status with 662 units available in inventory.

Equivalent and substitute parts are identified when design requirements permit component interchange based on matching electrical and mechanical specifications. Substitutes are necessary when primary part availability is limited, when alternative sourcing is required for supply chain optimization, or when design flexibility allows for functionally equivalent alternatives.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ICA-628-WGT is determined by strict alignment of the following critical parameters:

Position Count & Geometry: The substitute must accommodate 28 positions in a 2 x 14 configuration with 0.6" row spacing and 0.100" mating pitch. These parameters define physical compatibility with standard DIP package footprints.

Contact System: Both mating contact finish (gold) and mating contact material (beryllium copper) must match to ensure electrical performance and signal integrity equivalent to the original specification.

Mounting & Termination: Through-hole mounting type is required. Termination method differences (solder versus wire wrap) are permitted when the mounting footprint remains compatible.

Environmental Compliance: Operating temperature range of -55°C to 125°C must be maintained. RoHS compliance status is evaluated based on application requirements and regulatory context.

Electrical Performance: Current rating and contact resistance specifications establish the electrical envelope within which substitutes must operate.

The Mill-Max Manufacturing Corp. part number 123-93-628-41-001000 qualifies as a substitute based on matching position count, DIP configuration, row spacing, mating pitch, gold mating contact finish, beryllium copper mating contact material, through-hole mounting, and operating temperature range.

Engineering Selection Recommendations

ICA-628-WGT Selection Criteria:

Select the ICA-628-WGT when ROHS3 compliance is a mandatory requirement for the end application or when solder termination is the specified assembly method. This part maintains active production status with confirmed inventory availability of 662 units.

123-93-628-41-001000 Selection Criteria:

The Mill-Max substitute is electrically and mechanically compatible for applications where wire wrap termination is acceptable and where RoHS non-compliance does not present regulatory or contractual constraints. The higher current rating (3 A versus 1 A) provides additional electrical margin for applications requiring increased current capacity. Inventory availability is confirmed at 885 units.

Compliance Considerations:

Applications subject to RoHS3 regulations, EU directives, or customer specifications requiring RoHS compliance must use the ICA-628-WGT. Applications without RoHS mandates may utilize the Mill-Max substitute based on assembly process compatibility and electrical requirements.

Frequently Asked Questions (FAQ)

Q: Can the 123-93-628-41-001000 be used as a direct replacement for the ICA-628-WGT on a PCB designed for solder termination?

A: No. The ICA-628-WGT is specified for solder termination with 0.100" post pitch and tin finish. The 123-93-628-41-001000 is designed for wire wrap termination with 0.510" post length and tin-lead finish. PCB pad patterns and assembly processes differ between these termination methods. Substitution requires PCB redesign and assembly process modification.

Q: Are the mating contact specifications identical between these two parts?

A: Yes. Both parts feature gold-plated beryllium copper mating contacts with 30.0µin (0.76µm) finish thickness and 0.100" (2.54mm) pitch. Mating contact performance is equivalent for DIP package insertion and electrical connection.

Q: What is the impact of the current rating difference (1 A versus 3 A)?

A: The ICA-628-WGT is rated for 1 A maximum current per contact. The 123-93-628-41-001000 is rated for 3 A. For applications operating below 1 A per contact, both parts are suitable. For applications requiring 1 A to 3 A per contact, only the Mill-Max substitute meets the electrical specification.

Q: Does RoHS non-compliance of the Mill-Max part affect electrical performance?

A: RoHS compliance status does not affect electrical performance or functional compatibility. RoHS non-compliance indicates the presence of restricted substances (lead, cadmium, hexavalent chromium, etc.) in the component. Selection is determined by regulatory requirements and customer specifications, not by electrical characteristics.

Q: Are the housing materials compatible for thermal management?

A: The ICA-628-WGT uses polyester with glass filler. The 123-93-628-41-001000 uses polycyclohelylenedimethylene terephthalate (PCT) and polyester. Both materials provide equivalent thermal performance for DIP socket applications within the specified operating temperature range of -55°C to 125°C.

Q: Can these parts be intermixed in a production run?

A: No. Intermixing requires separate PCB designs and assembly process specifications due to termination method differences. Production runs must use a single part number with consistent assembly procedures.
