Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ICO-324-NGT is determined by strict alignment of critical electrical and mechanical parameters. The following parameters establish the substitution basis:

Primary Matching Criteria:

• Position count: 24 (2 x 12) configuration
• Socket type: DIP with 0.3" (7.62mm) row spacing
• Mating pitch: 0.100" (2.54mm)
• Post pitch: 0.100" (2.54mm)
• Mating contact finish: Gold plating
• Mating contact material: Beryllium Copper
• Mounting configuration: Through-hole solder termination
• Operating temperature range: -55°C ~ 125°C

The substitute part 115-93-324-41-003000 (Mill-Max Manufacturing Corp.) satisfies all primary matching criteria, enabling direct functional equivalence in applications where the ICO-324-NGT is specified. Variations in secondary parameters such as post contact finish thickness, current rating, and compliance certifications do not affect mechanical or electrical compatibility for standard DIP socket applications.

Parameter Comparison

Engineering Selection Recommendations

ICO-324-NGT Selection Criteria: The ICO-324-NGT is the primary choice for applications requiring ROHS3 compliance. This part maintains active product status with established supply availability (698 units in stock). The 1 A current rating and 10mOhm contact resistance are specified for standard DIP socket applications. The UL94 V-0 flammability rating supports use in regulated environments.

115-93-324-41-003000 Selection Criteria: The Mill-Max 115-93-324-41-003000 provides functional equivalence for applications where RoHS compliance is not a requirement. This substitute offers higher current capacity (3 A) and increased post contact finish thickness (200.0µin), which may provide extended service life in high-cycle insertion applications. The part maintains active status with higher inventory availability (886 units). The Tin-Lead post finish and non-compliant RoHS status restrict use to legacy systems or applications where lead-containing solder is acceptable.

Compliance Considerations: Selection between these parts depends on regulatory requirements. ROHS3-compliant designs must specify ICO-324-NGT. Applications without RoHS constraints may utilize either part based on current rating and insertion cycle requirements.

Frequently Asked Questions (FAQ)

Q: Can the 115-93-324-41-003000 be used as a direct replacement for the ICO-324-NGT in new designs?

A: The 115-93-324-41-003000 provides mechanical and electrical compatibility for DIP socket applications. However, the RoHS non-compliant status of the Mill-Max part restricts its use in designs requiring ROHS3 certification. New designs targeting regulated markets must specify the ICO-324-NGT.

Q: What is the significance of the post contact finish difference between these parts?

A: The ICO-324-NGT uses 10.0µin Tin finish on brass posts, while the 115-93-324-41-003000 uses 200.0µin Tin-Lead finish on brass alloy posts. The thicker finish on the Mill-Max part provides increased corrosion resistance and may extend service life in high-insertion-cycle applications. Both finishes support standard solder termination.

Q: Are there differences in current-carrying capacity between these sockets?

A: Yes. The ICO-324-NGT is rated for 1 A, while the 115-93-324-41-003000 is rated for 3 A. For applications requiring current levels above 1 A per pin, the Mill-Max part offers higher capacity. Standard DIP socket applications typically operate within the 1 A specification.

Q: What is the impact of the contact resistance specification on socket selection?

A: The ICO-324-NGT specifies 10mOhm contact resistance. The 115-93-324-41-003000 does not provide a contact resistance specification. For applications with strict contact resistance requirements, the ICO-324-NGT provides documented performance. Both parts use beryllium copper mating contacts, which typically exhibit similar resistance characteristics.

Q: Can these sockets be used interchangeably in existing PCB designs?

A: Yes. Both sockets share identical pitch specifications (0.100" mating and post pitch), 24-position configuration, and 0.3" row spacing. PCB footprints designed for either part accommodate both sockets without modification. Component selection depends on compliance requirements and performance specifications rather than physical compatibility.

Q: What packaging considerations apply to these substitute parts?

A: Both the ICO-324-NGT and 115-93-324-41-003000 are supplied in tube packaging. Inventory availability differs (698 units for Samtec, 886 units for Mill-Max), which may influence procurement decisions for high-volume applications.
