Engineering Selection Recommendations

All substitute parts listed maintain active product status and are manufactured by Kycon, Inc. within the KUSBX-SMT series. Selection between the main part KUSBX-SMT2AP5S-W and substitute parts should be based on:

Compliance Requirements: The main part carries RoHS Compliant status. Substitute parts KUSBX-SMT2AP1S-B, KUSBX-SMT2AP1S-B30, KUSBX-SMT2AP1S-W, KUSBX-SMT2AP1S-W30, and KUSBX-SMT2AP5S-B carry ROHS3 Compliant status with REACH Unaffected designation. Applications requiring specific RoHS compliance variants should reference the applicable regulatory requirements.

Insulation Color: The main part features white insulation. Black insulation variants (KUSBX-SMT2AP1S-B, KUSBX-SMT2AP1S-B30, KUSBX-SMT2AP5S-B) are available for applications requiring color differentiation or aesthetic specifications.

Inventory Availability: Substitute parts demonstrate varying stock levels. KUSBX-SMT2AP5S-B offers the highest inventory at 9954 pieces, while KUSBX-SMT2AP5S-W (main part) maintains 883 pieces.

Frequently Asked Questions (FAQ)

Q: Are all listed substitute parts electrically interchangeable with KUSBX-SMT2AP5S-W?

A: Yes. All substitute parts maintain identical electrical specifications including 1A current rating, 30VAC voltage rating, 4-position contact configuration, and gold-plated contact finish. Electrical interchangeability is confirmed across the complete parameter set.

Q: What is the difference between RoHS Compliant and ROHS3 Compliant status?

A: RoHS Compliant refers to the original Restriction of Hazardous Substances directive compliance. ROHS3 Compliant indicates compliance with the updated RoHS 3 directive (2011/65/EU as amended by 2015/863/EU). Applications subject to specific regulatory frameworks should confirm which compliance variant is required.

Q: Can I substitute a black insulation part for the white insulation main part?

A: Mechanically and electrically, yes. Black insulation variants (KUSBX-SMT2AP1S-B, KUSBX-SMT2AP1S-B30, KUSBX-SMT2AP5S-B) are fully compatible. However, if white insulation is specified for visual identification or design requirements, black variants should not be used without design review.

Q: Are there any differences in mounting or mechanical fit between substitute parts?

A: No. All parts share identical mounting specifications: surface mount with right-angle configuration, through-hole capability, and horizontal mounting feature. Mechanical fit and PCB layout compatibility are equivalent across all listed parts.

Q: Which substitute part should I select for maximum inventory availability?

A: KUSBX-SMT2AP5S-B offers the highest current inventory at 9954 pieces. This part is electrically and mechanically equivalent to the main part, with the only difference being black insulation color and ROHS3 compliance status.
