Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ICO-324-LGT is determined by the following critical parameters:

Mandatory Matching Parameters:

• Type: DIP, 0.3" (7.62mm) Row Spacing
• Number of Positions: 24 (2 x 12)
• Pitch - Mating: 0.100" (2.54mm)
• Contact Finish - Mating: Gold
• Mounting Type: Through Hole
• Termination: Solder
• Operating Temperature Range: -55°C ~ 125°C

The substitute part 115-93-324-41-001000 (Mill-Max Manufacturing Corp.) satisfies all mandatory matching parameters, establishing functional equivalence for standard DIP socket applications. Both parts feature identical mating contact specifications, position count, and pitch geometry, enabling direct mechanical and electrical interchangeability in circuit board designs.

Parameter Comparison

Engineering Selection Recommendations

ICO-324-LGT Selection Criteria:

• Applications requiring ROHS3 compliance
• Designs with RoHS3 certification requirements
• Systems where regulatory compliance documentation is mandatory

115-93-324-41-001000 Selection Criteria:

• Applications where RoHS compliance is not required
• Designs requiring higher current rating (3 A versus 1 A)
• Systems where tin-lead post finish is acceptable
• Applications utilizing PCT housing material specifications

Both parts maintain active production status and share identical mating contact specifications, pitch geometry, and operating temperature ranges. Selection between these parts depends on compliance requirements and current rating specifications for the target application.

Frequently Asked Questions (FAQ)

Q: Can the 115-93-324-41-001000 be used as a direct replacement for the ICO-324-LGT?

A: Yes, for applications where RoHS3 compliance is not required. Both sockets feature identical DIP configuration, 24-position count, 0.100" pitch, and gold-plated mating contacts. The mechanical and electrical interfaces are fully compatible.

Q: What is the primary difference between these two sockets?

A: The ICO-324-LGT is ROHS3 compliant with a 1 A current rating, while the 115-93-324-41-001000 is RoHS non-compliant with a 3 A current rating. Post finish differs (Tin versus Tin-Lead) and housing material composition varies between the two parts.

Q: Does the higher current rating of the 115-93-324-41-001000 affect compatibility?

A: No. The higher current rating (3 A) of the Mill-Max part does not create incompatibility. It indicates the part can safely handle higher current levels. Applications requiring only 1 A operation remain fully compatible with either socket.

Q: Are the mating contact specifications identical?

A: Yes. Both sockets feature beryllium copper mating contacts with gold finish at 30.0µin (0.76µm) thickness, 0.100" (2.54mm) pitch, and open frame configuration.

Q: Which socket should be selected for consumer electronics applications?

A: The ICO-324-LGT is appropriate for consumer electronics requiring ROHS3 compliance certification. The 115-93-324-41-001000 is suitable for applications where RoHS compliance is not a design requirement.

Q: Are both sockets rated for the same operating temperature range?

A: Yes. Both the ICO-324-LGT and 115-93-324-41-001000 operate across the -55°C to 125°C temperature range.

Q: What is the significance of the different post finish materials?

A: The ICO-324-LGT uses tin post finish (10.0µin thickness), while the 115-93-324-41-001000 uses tin-lead post finish (200.0µin thickness). Both finishes are suitable for solder termination. The tin-lead finish provides thicker plating coverage.
