Frequently Asked Questions (FAQ)

Q: Can the SCHURTER 5123.1003.0 directly replace the 5123.1003.0.21 in existing designs?

A: Yes. The 5123.1003.0 is a direct substitute with identical electrical ratings (4A, 250VAC), mechanical dimensions (29.00mm x 21.50mm panel cutout), connector style (IEC 320-C14), and compliance certifications (cURus, ENEC, ROHS3, UL94 V-0). No design modifications are required.

Q: What is the difference between part numbers 5123.1003.0.21 and 5123.1003.0?

A: The primary difference is product status. The 5123.1003.0.21 is classified as obsolete, while the 5123.1003.0 is active. Both components share identical specifications across all electrical, mechanical, and compliance parameters. The revision designation (.21 versus base number) reflects manufacturing or documentation updates, not functional changes.

Q: Are the panel cutout dimensions identical between these parts?

A: Yes. Both the 5123.1003.0.21 and 5123.1003.0 require a rectangular panel cutout of 29.00mm x 21.50mm and accommodate panel thickness of 0.315" (8.00mm). Existing panel designs require no modification.

Q: Does the substitute part maintain the same filtering characteristics?

A: Yes. The 5123.1003.0 incorporates identical filtering specifications: Filtered (EMI, RFI) - Commercial type with 4A current rating. EMI/RFI suppression performance is equivalent between both parts.

Q: What termination method is used on the substitute part?

A: Both the obsolete and active parts use Quick Connect termination with 0.250" (6.3mm) blade spacing. Wiring harness compatibility is maintained without modification.

Q: Are there any compliance or certification differences?

A: No. Both parts carry identical approval agency certifications (cURus, ENEC), ROHS3 compliance status, UL94 V-0 flammability rating, and IP40 ingress protection classification.

Q: What is the current inventory status of the substitute part?

A: The SCHURTER 5123.1003.0 has 654 pieces in stock as new original inventory, providing immediate availability for component procurement and system integration.
