ICO-308-AGT Equivalent & Substitute Parts

Part Overview

The ICO-308-AGT is an 8-position DIP socket manufactured by Samtec Inc., designed for through-hole mounting applications. This low-profile screw machine socket features gold-plated mating contacts and is rated for 1 A continuous current with a contact resistance of 10 mOhm. The part maintains active product status and is RoHS3 compliant, making it suitable for modern electronic assemblies requiring reliable IC interconnection in the 0.3" row spacing configuration.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across critical specifications including pin count, pitch, row spacing, contact materials, mounting type, and operating temperature range.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ICO-308-AGT is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Number of Positions: 8 (2 x 4)
• Type: DIP with 0.3" (7.62mm) Row Spacing
• Pitch - Mating: 0.100" (2.54mm)
• Pitch - Post: 0.100" (2.54mm)
• Contact Finish - Mating: Gold
• Contact Material - Mating: Beryllium Copper
• Mounting Type: Through Hole
• Termination: Solder
• Operating Temperature Range: -55°C ~ 125°C

The substitute part 111-93-308-41-001000 (Mill-Max Manufacturing Corp.) satisfies all mandatory matching parameters, establishing direct substitution eligibility. Variations in secondary parameters such as contact finish thickness on posts, post material composition, and current rating do not preclude substitution when the primary electrical and mechanical interfaces remain equivalent.

Engineering Selection Recommendations

ICO-308-AGT (Samtec Inc.) is the primary selection for applications requiring RoHS3 compliance. This part maintains active product status with full regulatory certification and is suitable for modern electronic assemblies subject to environmental and compliance restrictions.

111-93-308-41-001000 (Mill-Max Manufacturing Corp.) provides functional equivalence for applications where RoHS compliance is not mandated. This substitute offers higher current rating capacity (3 A versus 1 A) and increased post contact finish thickness (200.0µin versus 10.0µin), which may provide enhanced durability in high-cycle insertion applications. However, this part is RoHS non-compliant and should be selected only when regulatory requirements permit.

Both parts share identical mating contact specifications, pitch geometry, and operating temperature range, ensuring mechanical and electrical compatibility at the IC interface level.

Frequently Asked Questions (FAQ)

Q: Can 111-93-308-41-001000 be used as a direct replacement for ICO-308-AGT in all applications?

A: Functional substitution is valid for applications where RoHS compliance is not required. Both parts maintain identical pin count (8), pitch (0.100"), row spacing (0.3"), mating contact material (Beryllium Copper with gold finish), and operating temperature range (-55°C ~ 125°C). Selection depends on regulatory requirements and compliance mandates specific to the end application.

Q: What is the significance of the different current ratings (1 A vs. 3 A)?

A: The ICO-308-AGT is rated for 1 A continuous current, while the 111-93-308-41-001000 is rated for 3 A. Current rating reflects the maximum continuous current the socket contacts can safely carry. Applications requiring current levels between 1 A and 3 A may benefit from the higher-rated substitute, though both parts are electrically compatible at the mating interface.

Q: Why do the post contact finishes differ between these parts?

A: The ICO-308-AGT uses tin post finish (10.0µin thickness), while the 111-93-308-41-001000 uses tin-lead post finish (200.0µin thickness). Post finish affects solder joint formation and mechanical durability during PCB assembly. The thicker tin-lead finish on the substitute may provide enhanced durability in high-cycle insertion or rework scenarios. Both finishes are compatible with standard solder reflow processes.

Q: Are these parts mechanically interchangeable on the PCB?

A: Yes. Both parts share identical pitch specifications (0.100" mating and post pitch), row spacing (0.3"), mounting type (through hole), and open frame geometry. PCB footprints designed for the ICO-308-AGT will accommodate the 111-93-308-41-001000 without modification.

Q: What compliance considerations apply to part selection?

A: The ICO-308-AGT is RoHS3 compliant, meeting current environmental regulations for restricted substances. The 111-93-308-41-001000 is RoHS non-compliant. Applications subject to RoHS directives, customer specifications, or regional regulations must use the ICO-308-AGT. Both parts carry EAR99 export classification and share identical HTSUS tariff codes.
