ICO-286-S8A-T Equivalent & Substitute Parts

Part Overview

The ICO-286-S8A-T is a 28-position DIP socket manufactured by 3M, designed for through-hole mounting applications. This component features a 0.6" (15.24mm) row spacing with tin-plated phosphor bronze contacts and polyester glass-filled housing. The part is currently obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and component procurement.

Substitute Part Grouping Explanation

Substitution eligibility for the ICO-286-S8A-T is determined by the following critical parameters: 28-position configuration, 0.6" row spacing, 0.100" mating and post pitch, tin contact finish, through-hole mounting, solder termination, and UL94 V-0 flammability rating. The identified substitute parts maintain these core electrical and mechanical specifications, ensuring functional compatibility within the original application context.

Engineering Selection Recommendations

The 4828-6004-CP represents the primary substitute option, maintaining identical electrical and mechanical specifications to the ICO-286-S8A-T while offering active product status and ROHS3 compliance. This part is manufactured by 3M, the original equipment manufacturer, ensuring design continuity and supply chain consistency.

The 214-44-628-01-670800 from Mill-Max Manufacturing Corp. provides an alternative with enhanced specifications including higher current rating (3 A versus 1 A) and extended operating temperature range (-55°C ~ 125°C versus -65°C ~ 105°C). However, this part utilizes surface mount mounting technology rather than through-hole mounting, requiring PCB design modification. Additionally, the flammability rating is not specified for this component. Selection of this alternative requires verification of mounting compatibility with the original application.

Both substitute parts maintain the 28-position configuration, 0.6" row spacing, 0.100" pitch specifications, tin contact finish, and solder termination required for functional equivalence. Both are ROHS3 compliant and carry unlimited moisture sensitivity level (MSL 1) ratings.

Frequently Asked Questions (FAQ)

Q: Can the 4828-6004-CP directly replace the ICO-286-S8A-T without PCB modification?

A: Yes. The 4828-6004-CP maintains identical mounting type (through-hole), pitch specifications (0.100"), row spacing (0.6"), and position count (28). Direct PCB substitution is supported without design changes.

Q: What are the key differences between the 4828-6004-CP and the original ICO-286-S8A-T?

A: The 4828-6004-CP operates within a narrower temperature range (-25°C ~ 85°C versus -65°C ~ 105°C) and carries active product status with ROHS3 compliance, whereas the original part is obsolete and RoHS non-compliant. Electrical and mechanical specifications remain equivalent.

Q: Why is the 214-44-628-01-670800 listed as a substitute if it uses surface mount technology?

A: The 214-44-628-01-670800 maintains the core electrical specifications (28 positions, 0.6" row spacing, 0.100" pitch, tin finish, solder termination) but requires PCB redesign due to surface mount mounting type. This part is included as an alternative for applications where PCB modification is feasible and enhanced specifications (3 A current rating, -55°C ~ 125°C operating range) provide system benefits.

Q: Are there compatibility concerns with contact material differences?

A: The ICO-286-S8A-T and 4828-6004-CP both use phosphor bronze mating contacts, ensuring material compatibility. The 214-44-628-01-670800 uses beryllium copper for mating contacts, which maintains electrical performance within the specified pitch and current parameters but represents a material change requiring application-specific validation.

Q: What is the impact of the operating temperature range difference between substitutes?

A: The 4828-6004-CP operates from -25°C ~ 85°C, which is narrower than the original -65°C ~ 105°C range. Applications requiring operation below -25°C or above 85°C must use the original part or the 214-44-628-01-670800 (-55°C ~ 125°C). Verify application temperature requirements before selection.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both the 4828-6004-CP and 214-44-628-01-670800 are ROHS3 compliant. The original ICO-286-S8A-T is RoHS non-compliant. This compliance status may be a requirement for new designs or regulatory applications.
