Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the C8122-04 is determined by the following critical parameters:

Mechanical Compatibility:

• Number of positions: 22 (2 x 11)
• Row spacing: 0.4" (10.16mm)
• Pitch - mating: 0.100" (2.54mm)
• Mounting type: Through hole
• Termination type: Wire wrap

Electrical Compatibility:

• Operating temperature range must encompass or exceed the original specification
• Current rating must meet or exceed application requirements
• Contact material and finish must be compatible with mating components

Regulatory Compliance:

• RoHS3 compliance status
• REACH compliance status

The substitute part 123-43-422-41-001000 (Mill-Max Manufacturing Corp.) maintains identical mechanical dimensions and pin configuration, ensuring direct physical compatibility. Both parts share the same pitch specifications, mounting methodology, and wire wrap termination, allowing functional substitution in applications where the electrical and environmental parameters align.

Parameter Comparison

Engineering Selection Recommendations

The 123-43-422-41-001000 from Mill-Max Manufacturing Corp. is an active product with current manufacturing support, providing supply chain continuity for applications previously using the obsolete C8122-04. Both components maintain ROHS3 and REACH compliance, satisfying regulatory requirements for new designs and legacy system support.

The substitute part offers enhanced electrical performance with a 3 A current rating compared to the original 1.5 A specification, and an extended operating temperature range to 125°C versus 105°C. The gold contact finish on the mating side of the substitute part provides improved corrosion resistance and contact reliability compared to the tin finish of the original component.

Selection between these parts should be based on application-specific requirements for current capacity, temperature environment, and contact finish performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can the 123-43-422-41-001000 directly replace the C8122-04 in existing PCB designs?

A: Yes. Both components share identical mechanical specifications: 22-position DIP configuration, 0.4" row spacing, 0.100" pitch, through-hole mounting, and wire wrap termination. Physical and electrical compatibility is maintained for direct substitution.

Q: What are the differences in contact finish between these two parts?

A: The C8122-04 features tin contact finish on mating contacts, while the 123-43-422-41-001000 uses gold finish. Gold provides superior corrosion resistance and lower contact resistance in low-signal applications. Tin is suitable for standard signal and power applications.

Q: Does the higher current rating of the substitute part affect compatibility?

A: No. The 3 A rating of the 123-43-422-41-001000 exceeds the 1.5 A specification of the C8122-04. Applications designed for the original part will operate within the electrical envelope of the substitute.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the C8122-04 and 123-43-422-41-001000 are ROHS3 compliant and REACH unaffected, meeting current environmental and hazardous substance regulations.

Q: What is the significance of the extended temperature range in the substitute part?

A: The 123-43-422-41-001000 operates to 125°C compared to 105°C for the C8122-04. This extended range provides additional thermal margin for applications in elevated-temperature environments, though applications within the original 105°C limit remain fully compatible.

Q: Why is the C8122-04 listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The 123-43-422-41-001000 remains in active production, ensuring long-term component availability for new procurements and system maintenance.
