KB16SKW01-5F12-JB Equivalent & Substitute Parts

Part Overview

The KB16SKW01-5F12-JB is a pushbutton switch manufactured by NKK Switches, classified as SPDT (Single Pole Double Throw) with standard illumination and panel mount configuration. This component is currently listed as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and component procurement. The switch features a 1A current rating at 125V AC and 30V DC, with green LED illumination at 12VDC nominal voltage. Due to its obsolete status, sourcing equivalent or substitute components ensures design continuity and system reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB16SKW01-5F12-JB is determined by the following critical parameters:

Circuit configuration must remain SPDT with On-On switching function to maintain electrical compatibility with existing circuit designs. Voltage ratings must meet or exceed the original specifications: 125V AC and 30V DC minimum. Current rating must support the application load; the original 1A rating establishes the baseline requirement. Mounting type must be panel mount, front configuration to ensure mechanical fit within existing enclosures. Actuator type (square button) and illumination characteristics (LED, green, 12VDC) must match to preserve user interface consistency and control logic. Termination style compatibility depends on PCB or wiring harness design; both solder lug and quick connect options may be acceptable depending on assembly method. Panel cutout diameter is a critical mechanical constraint; substitutes with larger cutout dimensions (16.00mm) require panel modification.

The YB16SKW01-5F12-JB qualifies as a substitute based on matching SPDT circuit, On-On function, voltage ratings, mounting configuration, actuator type, and illumination specifications. However, differences in current rating, termination style, panel cutout diameter, and product status must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The YB16SKW01-5F12-JB is an active product from NKK Switches and represents a viable substitute for the obsolete KB16SKW01-5F12-JB when application requirements permit. Both components maintain ROHS3 compliance and identical voltage ratings, ensuring regulatory and electrical compatibility.

Selection of the YB16SKW01-5F12-JB is appropriate when the application can accommodate the following differences:

The increased current rating of 3A (versus 1A) provides enhanced capacity and does not create incompatibility with lower-current applications. The enhanced mechanical life (200,000 cycles versus 100,000 cycles) and electrical life (100,000 cycles versus 50,000 cycles) offer improved reliability and extended service intervals. The dual termination option (solder and quick connect) provides assembly flexibility; however, the quick connect feature requires compatible receptacles if utilized.

The panel cutout diameter increase from 12.30mm to 16.00mm requires mechanical evaluation. If the existing panel opening cannot be enlarged, the KB16SKW01-5F12-JB cannot be directly replaced without panel modification. Termination style compatibility must be confirmed against existing PCB or wiring harness design before component selection.

Frequently Asked Questions (FAQ)

Q: Can the YB16SKW01-5F12-JB directly replace the KB16SKW01-5F12-JB without any modifications?

A: Direct replacement is possible only if the panel cutout diameter of 16.00mm is compatible with the existing 12.30mm opening. If panel modification is not feasible, direct replacement is not recommended. Termination style must also be compatible with the existing assembly method.

Q: What is the primary reason the KB16SKW01-5F12-JB is considered obsolete?

A: The KB16SKW01-5F12-JB is listed as obsolete by the manufacturer. The YB16SKW01-5F12-JB, an active product, offers equivalent electrical functionality with enhanced performance characteristics.

Q: Are there any electrical compatibility concerns when substituting the YB16SKW01-5F12-JB?

A: No electrical compatibility concerns exist. Both components maintain identical voltage ratings (125V AC, 30V DC), SPDT circuit configuration, and On-On switching function. The higher current rating of the YB16SKW01-5F12-JB (3A) is backward-compatible with applications rated for 1A.

Q: What is the significance of the different termination styles?

A: The KB16SKW01-5F12-JB uses solder lug termination, while the YB16SKW01-5F12-JB offers both solder and quick connect options. Termination style selection depends on the assembly method and PCB design. Quick connect termination requires compatible receptacles.

Q: Do both components meet the same regulatory compliance standards?

A: Yes. Both the KB16SKW01-5F12-JB and YB16SKW01-5F12-JB are ROHS3 compliant and carry identical ECCN and HTSUS classifications, ensuring regulatory equivalence.

Q: What mechanical considerations should be evaluated before substitution?

A: Panel cutout diameter is the primary mechanical constraint. The YB16SKW01-5F12-JB requires a 16.00mm circular opening, compared to 12.30mm for the original component. Panel modification may be necessary. Mounting type (panel mount, front) and actuator configuration (square button) are identical and present no compatibility issues.
