Parameter Comparison

Engineering Selection Recommendations

The 4808-3004-CP is an active substitute for the obsolete ICO-083-S8A-T. Both components share identical electrical and mechanical specifications for socket configuration, contact materials, and current rating.

Product Status Consideration: The ICO-083-S8A-T is obsolete, while the 4808-3004-CP is active and maintains current manufacturing support from 3M.

Compliance Consideration: The 4808-3004-CP is ROHS3 compliant, whereas the ICO-083-S8A-T is RoHS non-compliant. Applications subject to RoHS regulations require the 4808-3004-CP.

Operating Temperature Consideration: The ICO-083-S8A-T operates across -65°C to 105°C, while the 4808-3004-CP operates across -25°C to 85°C. Applications requiring operation below -25°C or above 85°C must evaluate temperature compatibility.

Contact Finish Thickness: The 4808-3004-CP provides specified contact finish thickness (35.4µin mating, 35.0µin post), whereas the ICO-083-S8A-T does not specify this parameter.

Frequently Asked Questions (FAQ)

Q: Can the 4808-3004-CP directly replace the ICO-083-S8A-T in existing designs?

A: Yes, for applications operating within -25°C to 85°C. Both components feature identical 8-position DIP socket configuration with 0.3" row spacing, 0.100" pitch, tin-plated phosphor bronze contacts, and 1 A current rating. Applications requiring operation outside the 4808-3004-CP temperature range must retain the ICO-083-S8A-T or identify alternative solutions.

Q: What is the difference in packaging between these parts?

A: The ICO-083-S8A-T packaging is not specified in available data. The 4808-3004-CP is supplied in Tube packaging.

Q: Are there RoHS compliance implications for substitution?

A: Yes. The ICO-083-S8A-T is RoHS non-compliant, while the 4808-3004-CP is ROHS3 compliant. Designs subject to RoHS directives must use the 4808-3004-CP.

Q: What are the key electrical parameters that determine socket compatibility?

A: Socket compatibility is determined by number of positions (8), row spacing (0.3"), mating pitch (0.100"), post pitch (0.100"), contact material (phosphor bronze), contact finish (tin), and current rating (1 A). Both the ICO-083-S8A-T and 4808-3004-CP meet these specifications.

Q: Are moisture sensitivity levels equivalent between these parts?

A: Yes. Both components are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
