Substitute Part Grouping Explanation

Substitution eligibility for DIP socket connectors is determined by strict mechanical and electrical compatibility criteria. The following parameters must match or be compatible:

Critical Matching Parameters:

Number of positions: 32 (2 x 16)
Row spacing: 0.6" (15.24mm)
Pitch - Mating: 0.100" (2.54mm)
Pitch - Post: 0.100" (2.54mm)
Mounting type: Through Hole
Contact material: Phosphor Bronze
Contact finish: Tin
Housing material: Polyester, Glass Filled
Flammability rating: UL94 V-0
Current rating: 1 A
Termination: Solder

The substitute part 4832-6004-CP meets all critical mechanical and electrical parameters required for direct substitution. Both parts share identical pin configuration, pitch specifications, contact materials, and housing properties. The substitute is manufactured by 3M and maintains the same functional characteristics necessary for IC and transistor socket applications.

Engineering Selection Recommendations

The 4832-6004-CP serves as the direct functional equivalent to the obsolete ICO-326-S8A-T. Both components are manufactured by 3M and share identical mechanical and electrical specifications for DIP socket applications.

Product Status Consideration: The ICO-326-S8A-T is obsolete, while 4832-6004-CP is in active production. Selection of the active part ensures ongoing availability and supply chain continuity.

Compliance Status: The 4832-6004-CP is ROHS3 compliant, whereas the original part is RoHS non-compliant. This distinction is relevant for applications subject to RoHS regulations.

Operating Temperature Range: The original part operates from -65°C to 105°C, while the substitute operates from -25°C to 85°C. Applications requiring the full temperature range of the original part must account for this narrower specification in the substitute.

Packaging: The substitute is supplied in tube packaging, which may differ from the original part's packaging configuration.

Frequently Asked Questions (FAQ)

Q: Can 4832-6004-CP be used as a direct replacement for ICO-326-S8A-T?

A: Yes. Both parts share identical pin counts (32 positions), row spacing (0.6"), pitch specifications (0.100"), contact materials (phosphor bronze with tin finish), housing material (polyester glass-filled), and current ratings (1 A). Mechanical and electrical compatibility is confirmed.

Q: What is the primary reason for substitution?

A: The ICO-326-S8A-T is classified as obsolete. The 4832-6004-CP is the current production equivalent from the same manufacturer, ensuring component availability and supply chain support.

Q: Are there temperature range differences between these parts?

A: Yes. The original part operates from -65°C to 105°C, while the substitute operates from -25°C to 85°C. Applications requiring operation below -25°C or above 85°C must evaluate whether the substitute's narrower range is acceptable for the intended use.

Q: Does the substitute meet RoHS requirements?

A: The 4832-6004-CP is ROHS3 compliant. The original ICO-326-S8A-T is RoHS non-compliant. This is relevant for applications subject to RoHS regulations or customer requirements.

Q: Is the packaging the same?

A: The substitute is supplied in tube packaging. Verify that tube packaging is compatible with your procurement and assembly processes.

Q: Are both parts suitable for through-hole soldering?

A: Yes. Both parts are designed for through-hole mounting with solder termination and feature identical termination specifications.
