ICO-308-CGT DIP Socket Equivalent & Substitute Parts

Part Overview

The ICO-308-CGT is an 8-position DIP socket manufactured by Samtec Inc., designed for through-hole mounting applications requiring gold-plated mating contacts. This component is classified as an active product with full RoHS3 compliance. The socket accommodates dual inline package (DIP) integrated circuits with 0.3" (7.62mm) row spacing and 0.100" (2.54mm) pitch contacts.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across critical specifications including pin count, pitch dimensions, contact materials, mounting type, and operating temperature range. Identifying qualified substitutes ensures design flexibility and supply chain continuity.

Parameter Comparison

Engineering Selection Recommendations

Both the ICO-308-CGT and 110-43-308-41-001000 are active products with ROHS3 compliance and EAR99 export classification. Selection between these parts is based on the following engineering criteria:

ICO-308-CGT (Samtec Inc.):

• Current rating: 1 A
• Contact post finish thickness: 10.0µin (0.25µm)
• Housing material: Polyester, Glass Filled
• Suitable for standard DIP socket applications within 1 A current specifications

110-43-308-41-001000 (Mill-Max Manufacturing Corp.):

• Current rating: 3 A
• Contact post finish thickness: 200.0µin (5.08µm)
• Housing material: Polycyclohexylenedimethylene Terephthalate (PCT), Polyester
• Termination post length: 0.125" (3.18mm)
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected
• Suitable for applications requiring higher current capacity or enhanced post durability

Both parts maintain equivalent mechanical fit, electrical contact characteristics, and thermal operating range. Selection should be based on application current requirements and PCB design specifications.

Frequently Asked Questions (FAQ)

Q: Can the 110-43-308-41-001000 be used as a direct replacement for the ICO-308-CGT on existing PCBs?

A: Yes. Both parts share identical pitch dimensions (0.100" mating and post), 8-position DIP configuration with 0.3" row spacing, gold-plated beryllium copper mating contacts, and through-hole solder termination. PCB footprints are mechanically compatible.

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

A: The ICO-308-CGT has 10.0µin (0.25µm) tin finish on brass posts, while the 110-43-308-41-001000 has 200.0µin (5.08µm) tin finish. The thicker finish on the Mill-Max part provides enhanced durability and corrosion resistance during repeated insertion cycles and extended storage.

Q: Why do the two parts have different current ratings?

A: The ICO-308-CGT is rated for 1 A, while the 110-43-308-41-001000 is rated for 3 A. This difference reflects design variations in contact geometry and material composition. Applications requiring current levels above 1 A should specify the Mill-Max part.

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

A: Yes. Both the ICO-308-CGT and 110-43-308-41-001000 operate across -55°C to 125°C, ensuring thermal compatibility in equivalent applications.

Q: What is the difference in housing material between these parts?

A: The ICO-308-CGT uses Polyester with glass filler, while the 110-43-308-41-001000 uses Polycyclohexylenedimethylene Terephthalate (PCT) with polyester. Both materials provide adequate mechanical support and electrical isolation for DIP socket applications.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the ICO-308-CGT and 110-43-308-41-001000 are ROHS3 compliant, meeting current environmental and hazardous substance restrictions.

Q: What does the Moisture Sensitivity Level (MSL) rating of 1 indicate for the Mill-Max part?

A: MSL 1 indicates unlimited moisture sensitivity, meaning the component can be stored indefinitely without moisture bake-out requirements prior to soldering.
