Key Parameters

Substitute Part Grouping Explanation

The 4816-3004-CP qualifies as a direct substitute for the ICO-163-S8A-T based on matching electrical and mechanical parameters. Substitution eligibility is determined by the following critical parameters:

• 16-position configuration (2 x 8 grid)
• 0.3" (7.62mm) row spacing
• 0.100" (2.54mm) mating pitch
• Tin contact finish on phosphor bronze mating contacts
• Through-hole solder termination
• Polyester glass-filled housing
• UL94 V-0 flammability rating
• 1 A current rating

Both components share identical mechanical interfaces and electrical characteristics within these parameters, enabling direct substitution in applications requiring 16-position DIP sockets.

Parameter Comparison

Engineering Selection Recommendations

The 4816-3004-CP is the appropriate substitute for the obsolete ICO-163-S8A-T. Both components are manufactured by 3M and share identical electrical and mechanical specifications for the critical parameters governing DIP socket functionality.

The 4816-3004-CP offers the additional advantage of active product status, ensuring ongoing availability and supply chain continuity. The substitute also provides RoHS compliance, meeting current regulatory requirements for electronic component manufacturing and assembly.

For applications subject to RoHS directives or requiring components with active manufacturer support, the 4816-3004-CP is the specified replacement. The identical pin configuration, pitch, contact materials, and current rating ensure direct compatibility with existing PCB designs and component footprints.

Frequently Asked Questions (FAQ)

Q: Can the 4816-3004-CP be used as a direct replacement for the ICO-163-S8A-T?

A: Yes. Both components share identical 16-position DIP configuration, 0.3" row spacing, 0.100" mating pitch, tin-plated phosphor bronze contacts, and 1 A current rating. The mechanical and electrical interfaces are equivalent, enabling direct substitution without PCB redesign.

Q: What is the difference in operating temperature range between these parts?

A: The ICO-163-S8A-T operates from -65°C to 105°C, while the 4816-3004-CP operates from -25°C to 85°C. For applications requiring the extended lower temperature range of the original part, this difference must be evaluated against specific system requirements.

Q: Does the 4816-3004-CP meet RoHS compliance requirements?

A: Yes. The 4816-3004-CP is RoHS compliant, whereas the ICO-163-S8A-T is RoHS non-compliant. This makes the substitute suitable for applications and markets requiring RoHS-compliant components.

Q: Are there packaging differences between these components?

A: The ICO-163-S8A-T packaging is not specified in the available data. The 4816-3004-CP is supplied in tube packaging. Confirm packaging requirements for your specific procurement and assembly processes.

Q: What is the contact finish thickness specification for the 4816-3004-CP?

A: The 4816-3004-CP has a contact finish thickness of 35.4µin (0.90µm) on mating contacts and 35.0µin (0.90µm) on post contacts. The ICO-163-S8A-T contact finish thickness is not specified in available data.
