Engineering Selection Recommendations

The 4832-6000-CP is the direct equivalent for the obsolete ICO-326-S8-T based on matching electrical and mechanical specifications across all critical parameters. The substitute part maintains identical pin configuration, pitch, contact materials, and current rating.

The 4832-6000-CP offers the advantage of active product status, ensuring ongoing availability and supply chain continuity. The part achieves ROHS3 compliance, meeting current regulatory requirements for new designs and procurement cycles.

Operating temperature range differs between the parts: the original ICO-326-S8-T operates from -65°C to 105°C, while the 4832-6000-CP operates from -25°C to 85°C. Component selection must account for application-specific temperature requirements. For applications requiring the extended lower temperature range of -65°C, the original specification must be verified against system thermal operating conditions.

Both parts carry identical moisture sensitivity classification (MSL 1) and flammability rating (UL94 V-0), ensuring equivalent environmental performance in standard storage and operational conditions.

Frequently Asked Questions (FAQ)

Q: Can the 4832-6000-CP directly replace the ICO-326-S8-T in existing PCB designs?

A: Yes, the 4832-6000-CP provides direct mechanical and electrical compatibility. Both parts feature identical 32-position DIP configuration with 0.6" row spacing, 0.100" pitch, and through-hole solder termination. PCB footprints designed for the ICO-326-S8-T will accommodate the 4832-6000-CP without modification.

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

A: The ICO-326-S8-T is obsolete, while the 4832-6000-CP is an active product. The 4832-6000-CP achieves ROHS3 compliance and specifies contact finish thickness values. Operating temperature range differs: the original supports -65°C to 105°C, while the substitute supports -25°C to 85°C.

Q: Are there packaging differences between the ICO-326-S8-T and 4832-6000-CP?

A: The 4832-6000-CP is supplied in tube packaging. Original packaging for the ICO-326-S8-T is not specified in available documentation. Verify packaging requirements for your procurement and assembly processes.

Q: Does the 4832-6000-CP meet current regulatory requirements?

A: Yes, the 4832-6000-CP is ROHS3 compliant and carries EAR99 export classification. Both parts maintain UL94 V-0 flammability rating and MSL 1 moisture sensitivity classification.

Q: What applications require verification of the operating temperature range?

A: Applications operating below -25°C or above 85°C require evaluation against the 4832-6000-CP specifications. If your system requires the full -65°C to 105°C range of the original ICO-326-S8-T, confirm that the substitute's narrower range meets thermal operating conditions before implementation.
