Substitute Part Grouping Explanation

Substitution for the TE Connectivity 1-390262-1 is determined by strict alignment of the following critical parameters:

Primary Substitution Criteria:

Number of positions: 24 (2 x 12)
Row spacing: 0.3" (7.62mm)
Pitch - mating: 0.100" (2.54mm)
Contact finish: Tin
Contact material: Phosphor Bronze
Mounting type: Through hole
Termination: Solder

Direct Equivalent: The 3M 4824-3000-CP meets all primary substitution criteria and is classified as a direct equivalent. This part maintains identical position count, row spacing, mating pitch, contact finish, contact material, mounting type, and termination method. The 3M part is currently in active production status, providing reliable procurement availability.

Similar Substitute with Design Considerations: The Adam Tech ICS-624-T shares the same position count, mating pitch, contact finish, and contact material. However, this part features a 0.6" (15.24mm) row spacing, which differs from the 0.3" (7.62mm) row spacing of the main part. This dimensional difference requires PCB layout verification before implementation.

Engineering Selection Recommendations

For Direct Replacement (Recommended): The 3M 4824-3000-CP is the primary substitute for the TE Connectivity 1-390262-1. This part maintains identical mechanical and electrical specifications across all critical parameters, including row spacing, mating pitch, contact finish, and contact material. The 3M part is in active production status, ensuring long-term availability and supply chain stability. Both parts are ROHS3 compliant with MSL rating of 1 (Unlimited), supporting equivalent environmental and reliability requirements.

For Applications with Layout Flexibility: The Adam Tech ICS-624-T provides an alternative when PCB layout accommodates the 0.6" (15.24mm) row spacing. This part offers an extended operating temperature range (-55°C ~ 105°C) compared to the main part (-40°C ~ 105°C) and lower contact resistance (20mOhm versus 30mOhm). The Adam Tech part is also in active production status and maintains ROHS3 compliance. Implementation requires verification that the increased row spacing is compatible with existing PCB footprints and circuit design requirements.

Frequently Asked Questions (FAQ)

Q: Can the 3M 4824-3000-CP be used as a direct replacement for the TE Connectivity 1-390262-1?

A: Yes. The 3M 4824-3000-CP is a direct equivalent. Both parts share identical row spacing (0.3"), mating pitch (0.100"), position count (24), contact finish (tin), contact material (phosphor bronze), and termination method (solder). No design modifications are required for substitution.

Q: What is the primary difference between the 3M 4824-3000-CP and the Adam Tech ICS-624-T?

A: The primary difference is row spacing. The 3M part maintains the 0.3" (7.62mm) row spacing of the original TE Connectivity part, while the Adam Tech part features 0.6" (15.24mm) row spacing. This dimensional difference affects PCB footprint compatibility and requires layout verification before use.

Q: Are all three parts RoHS compliant?

A: Yes. The TE Connectivity 1-390262-1, 3M 4824-3000-CP, and Adam Tech ICS-624-T are all ROHS3 compliant with MSL rating of 1 (Unlimited).

Q: Does the operating temperature range differ between the substitute parts?

A: Yes. The TE Connectivity part operates from -40°C to 105°C, the 3M part from -25°C to 85°C, and the Adam Tech part from -55°C to 105°C. Application requirements must be verified against the selected substitute's temperature range.

Q: What is the contact resistance specification for each part?

A: The TE Connectivity 1-390262-1 specifies 30mOhm contact resistance. The Adam Tech ICS-624-T specifies 20mOhm. The 3M 4824-3000-CP does not provide a contact resistance specification in available documentation.

Q: Are packaging differences significant for procurement?

A: Both substitute parts are supplied in tube packaging. The TE Connectivity part packaging is not specified. Tube packaging is standard for DIP socket components and does not affect electrical or mechanical performance.
