Substitute Part Grouping Explanation

The 4840-6000-CP qualifies as a direct substitute for the ICO-406-S8-T based on matching electrical and mechanical parameters. Substitution is valid when the following criteria are met:

• Position count: 40 (2 x 20) configuration
• Row spacing: 0.6" (15.24mm)
• Mating pitch: 0.100" (2.54mm)
• Post pitch: 0.100" (2.54mm)
• Contact material: Phosphor Bronze
• Contact finish: Tin plating
• Mounting method: Through Hole, Solder termination
• Housing material: Polyester, Glass Filled
• Flammability rating: UL94 V-0
• Current rating: 1 A
• Moisture sensitivity: MSL 1

The 4840-6000-CP maintains all critical mechanical and electrical specifications required for direct functional replacement in applications originally designed for the ICO-406-S8-T.

Parameter Comparison

Engineering Selection Recommendations

The 4840-6000-CP is the direct functional equivalent for the obsolete ICO-406-S8-T. Selection of this substitute is based on:

• All critical electrical parameters match: 40-position configuration, 0.100" pitch, 1 A current rating, identical contact materials and finishes
• All mechanical parameters match: 0.6" row spacing, through-hole mounting, polyester glass-filled housing, UL94 V-0 flammability rating
• The substitute is actively produced by the original manufacturer (3M), ensuring long-term availability
• The 4840-6000-CP meets ROHS3 compliance, addressing regulatory requirements for new designs and procurement
• Operating temperature range of the substitute (-25°C ~ 85°C) is narrower than the original part (-65°C ~ 105°C); applications requiring extended temperature operation below -25°C or above 85°C must be evaluated for compatibility
• Packaging format differs (Tube vs. unspecified for original); verify packaging requirements for your procurement process

Frequently Asked Questions (FAQ)

Q: Can the 4840-6000-CP be used as a direct replacement for the ICO-406-S8-T?

A: Yes. The 4840-6000-CP matches all critical electrical and mechanical specifications: 40-position DIP socket, 0.6" row spacing, 0.100" pitch, phosphor bronze tin-plated contacts, through-hole solder termination, and UL94 V-0 housing. Both parts are manufactured by 3M and are functionally equivalent.

Q: What is the difference in operating temperature range?

A: The ICO-406-S8-T operates from -65°C to 105°C, while the 4840-6000-CP operates from -25°C to 85°C. If your application requires operation outside the -25°C to 85°C range, the substitute may not be suitable without additional thermal analysis.

Q: Does the 4840-6000-CP meet RoHS requirements?

A: Yes. The 4840-6000-CP is ROHS3 compliant, whereas the original ICO-406-S8-T is RoHS non-compliant. This makes the substitute suitable for applications and regions with RoHS regulatory requirements.

Q: Are there packaging differences between these parts?

A: The 4840-6000-CP is supplied in Tube packaging. Verify that your procurement and assembly processes accommodate this packaging format.

Q: What are the key parameters that determine substitutability for 40-position DIP sockets?

A: Position count (40), row spacing (0.6"), mating pitch (0.100"), post pitch (0.100"), contact material (phosphor bronze), contact finish (tin), mounting type (through hole), housing material (polyester glass-filled), and current rating (1 A) are the critical parameters. Deviations in any of these specifications indicate incompatibility.

Q: Is the 4840-6000-CP still in production?

A: Yes. The 4840-6000-CP has an Active product status with 4227 units in stock, ensuring availability for new orders and ongoing production requirements.
