Key Parameters

Substitute Part Grouping Explanation

The 4808-3000-CP qualifies as a direct substitute based on the following critical parameters that determine functional equivalence:

• Socket Configuration: Both parts feature 8-position DIP socket architecture with 0.3" (7.62mm) row spacing
• Pitch Specifications: Mating pitch of 0.100" (2.54mm) and post pitch of 0.100" (2.54mm) are identical
• Contact System: Both utilize tin-plated phosphor bronze contacts for mating and post connections
• Mounting Method: Through-hole solder termination on both components
• Current Rating: 1 A rating maintained across both parts
• Housing Material: Polyester, glass-filled construction in both designs
• Flammability Compliance: UL94 V-0 rating consistent between parts

The 4808-3000-CP represents an active production equivalent from the same manufacturer, providing direct functional replacement capability for the obsolete ICO-083-S8-T.

Parameter Comparison

Engineering Selection Recommendations

The 4808-3000-CP is the direct functional equivalent for the obsolete ICO-083-S8-T. Selection of this substitute is based on the following engineering factors:

Product Status: The ICO-083-S8-T is obsolete and no longer manufactured. The 4808-3000-CP is in active production status, ensuring long-term supply chain availability and consistent quality control.

Compliance Status: The 4808-3000-CP meets ROHS3 compliance requirements, whereas the original part is RoHS non-compliant. For new designs and applications subject to RoHS regulations, the substitute provides regulatory alignment.

Electrical and Mechanical Compatibility: All critical parameters determining socket functionality—pin count, pitch specifications, contact materials, current rating, and mounting method—are identical between the two parts. Direct PCB footprint compatibility is maintained.

Operating Temperature Consideration: The substitute operates within -25°C to 85°C, compared to the original -65°C to 105°C range. Applications requiring operation below -25°C or above 85°C must evaluate this parameter against specific system requirements.

Packaging: The substitute is supplied in tube packaging, whereas original packaging information is not specified. Verify packaging requirements for your procurement and assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the 4808-3000-CP be used as a direct replacement for the ICO-083-S8-T on existing PCBs?

A: Yes. The 4808-3000-CP maintains identical pitch specifications (0.100" mating and post), 8-position DIP configuration with 0.3" row spacing, and through-hole solder termination. PCB footprints are directly compatible without modification.

Q: What is the primary reason for substitution?

A: The ICO-083-S8-T is classified as obsolete and is no longer in active production. The 4808-3000-CP is the active equivalent from 3M, ensuring continued availability and supply chain reliability.

Q: Are there any electrical performance differences between these parts?

A: No. Both parts feature identical contact materials (phosphor bronze with tin plating), current rating (1 A), and contact finish specifications. Electrical performance is equivalent.

Q: Does the operating temperature range difference affect compatibility?

A: The substitute operates within -25°C to 85°C versus the original -65°C to 105°C. For applications operating within the substitute's temperature range, there is no functional impact. Applications requiring extended temperature operation below -25°C or above 85°C must evaluate this limitation against system specifications.

Q: What is the significance of the RoHS compliance difference?

A: The substitute is ROHS3 compliant, meeting current environmental and regulatory requirements. The original part is RoHS non-compliant. For new designs and regulated applications, the substitute provides compliance alignment. Existing legacy systems using the original part are not affected by this difference.

Q: Are the contact finish thicknesses specified for the substitute?

A: Yes. The 4808-3000-CP specifies contact finish thickness of 35.4µin (0.90µm) for mating contacts and 35.0µin (0.90µm) for post contacts. The original part does not provide this specification.

Q: What packaging is supplied with the 4808-3000-CP?

A: The 4808-3000-CP is supplied in tube packaging. Confirm packaging requirements for your assembly and procurement processes.
