ICO-324-AGT DIP Socket Equivalent & Substitute Parts

Part Overview

The ICO-324-AGT is a 24-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 0.3" (7.62mm) row spacing and 0.100" (2.54mm) pitch. The part is currently in active production status with 898 units available in inventory. Substitute parts are identified when equivalent electrical and mechanical specifications are required due to component availability, supply chain considerations, or design flexibility within established parameter tolerances.

Key Parameters

Substitute Part Grouping Explanation

The ICO-324-AGT and its identified substitute, the 111-93-324-41-001000 (Mill-Max Manufacturing Corp.), are classified as equivalent substitutes based on the following critical parameters:

Matching Electrical and Mechanical Specifications:

• Identical position count: 24 (2 x 12)
• Identical row spacing: 0.3" (7.62mm)
• Identical mating pitch: 0.100" (2.54mm)
• Identical mating contact finish: Gold with 30.0µin (0.76µm) thickness
• Identical mating contact material: Beryllium Copper
• Identical mounting type: Through Hole
• Identical termination method: Solder
• Identical operating temperature range: -55°C ~ 125°C
• Identical HTSUS classification: 8536.69.4040

These parameters define the functional interchangeability of DIP sockets within this category. Variations in post contact finish, post contact material composition, and housing material polymer type do not affect the socket's primary function of accepting and retaining a 24-pin DIP integrated circuit.

Parameter Comparison

Engineering Selection Recommendations

ICO-324-AGT Selection Criteria:

• Required when ROHS3 compliance is mandatory for the end application
• Specified current rating of 1 A is sufficient for standard DIP IC applications
• Samtec manufacturing source preferred when supply chain continuity with existing Samtec components is established
• Contact resistance specification of 10mOhm is documented and verified

111-93-324-41-001000 Selection Criteria:

• Suitable for applications where RoHS compliance is not required
• Higher current rating of 3 A provides margin for applications with elevated current demands
• Mill-Max manufacturing source acceptable when component availability from Samtec is constrained
• Tin-Lead post finish and thicker post plating (200.0µin) may provide enhanced durability in high-cycle insertion applications
• PCT housing material offers improved thermal stability compared to standard polyester

Compliance Considerations: The ICO-324-AGT maintains ROHS3 compliance status, making it the required selection for applications subject to European Union Restriction of Hazardous Substances regulations. The 111-93-324-41-001000 is RoHS non-compliant and must not be substituted in applications where RoHS compliance is contractually or regulatory mandated.

Frequently Asked Questions (FAQ)

Q: Can the 111-93-324-41-001000 be used as a direct replacement for the ICO-324-AGT in all applications?

A: The 111-93-324-41-001000 is mechanically and electrically compatible for DIP IC socket applications. However, substitution is restricted in applications requiring RoHS3 compliance. The ICO-324-AGT must be used when regulatory or contractual RoHS requirements apply.

Q: What is the significance of the different post contact finishes (Tin vs. Tin-Lead)?

A: Both finishes provide adequate solder joint formation and electrical continuity. The Tin-Lead finish on the Mill-Max part (111-93-324-41-001000) is thicker at 200.0µin compared to the Tin finish on the Samtec part at 10.0µin. Thicker plating may extend socket life in applications with frequent IC insertion and removal cycles.

Q: Are the housing materials functionally equivalent?

A: Both housing materials (Polyester, Glass Filled for ICO-324-AGT and PCT Polyester for 111-93-324-41-001000) provide adequate mechanical support and thermal stability within the specified operating temperature range of -55°C to 125°C. Material selection does not affect socket function for standard DIP IC applications.

Q: Why is the current rating different between the two parts?

A: The ICO-324-AGT is rated at 1 A while the 111-93-324-41-001000 is rated at 3 A. Both ratings exceed typical DIP IC current requirements. The higher rating on the Mill-Max part reflects its thicker post plating and Tin-Lead finish composition, which provide greater current-carrying capacity.

Q: What does the 0.3" (7.62mm) row spacing specification mean?

A: Row spacing defines the distance between the two parallel rows of contact pins. The 0.3" specification is the standard spacing for 24-pin DIP integrated circuits. Both sockets accommodate DIP ICs with this exact row spacing.

Q: Can these sockets be used interchangeably on the same PCB assembly line?

A: Mechanical and electrical interchangeability is confirmed. However, RoHS compliance status must be verified against assembly line requirements and end-product regulatory obligations before substitution.

Q: What is the significance of the 0.100" (2.54mm) pitch specification?

A: Pitch defines the center-to-center distance between adjacent contact pins. The 0.100" specification is standard for DIP sockets and ensures compatibility with all 24-pin DIP integrated circuits manufactured to industry standards.
