Key Parameters

Substitute Part Grouping Explanation

The 4820-3000-CP qualifies as a direct substitute for the ICO-203-S8-T based on the following critical parameters:

• 20-position configuration (2 x 10) matching the original pin count
• 0.3" (7.62mm) row spacing identical to the main part
• 0.100" (2.54mm) mating and post pitch specifications
• Tin contact finish on both mating and post surfaces
• Phosphor bronze contact material
• Through-hole mounting compatibility
• Polyester glass-filled housing material
• 1 A current rating
• UL94 V-0 flammability classification
• MSL 1 moisture sensitivity level

The substitute maintains electrical and mechanical compatibility across all specified parameters, enabling direct replacement in applications requiring 20-position DIP sockets with standard 0.3" row spacing.

Parameter Comparison

Engineering Selection Recommendations

The 4820-3000-CP serves as the primary substitute for the obsolete ICO-203-S8-T. The substitute part maintains identical electrical and mechanical specifications across all critical parameters, ensuring functional compatibility in existing circuit designs.

The 4820-3000-CP offers the additional advantage of active product status, ensuring continued availability for procurement and support. The part achieves ROHS3 compliance, meeting current environmental and regulatory requirements for new designs and manufacturing processes.

Both parts share identical contact specifications, mounting characteristics, and thermal ratings, eliminating the need for circuit board redesign or component qualification testing when transitioning from the obsolete ICO-203-S8-T to the 4820-3000-CP.

Frequently Asked Questions (FAQ)

Q: Can the 4820-3000-CP be used as a direct replacement for the ICO-203-S8-T?

A: Yes. The 4820-3000-CP matches all critical electrical and mechanical parameters of the ICO-203-S8-T, including pin count, row spacing, pitch, contact materials, and current rating. No circuit board modifications are required.

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

A: The ICO-203-S8-T is obsolete, while the 4820-3000-CP maintains active product status. Additionally, the 4820-3000-CP achieves ROHS3 compliance, whereas the ICO-203-S8-T is non-compliant.

Q: Are the operating temperature ranges compatible?

A: The ICO-203-S8-T operates from -65°C to 105°C, while the 4820-3000-CP operates from -25°C to 85°C. Applications requiring the full -65°C to 105°C range must evaluate whether the 4820-3000-CP's narrower range meets system requirements.

Q: What packaging format is available for the 4820-3000-CP?

A: The 4820-3000-CP is supplied in tube packaging, suitable for automated assembly and manual component handling.

Q: Are both parts manufactured by the same company?

A: Yes. Both the ICO-203-S8-T and 4820-3000-CP are manufactured by 3M, ensuring consistent quality standards and contact specifications.
