KB16KKG01 Equivalent & Substitute Parts

Part Overview

The KB16KKG01 is a pushbutton switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) circuit configuration with 0.4VA current rating at 28V AC/DC. This component is designed for standard panel mount, snap-in applications with solder lug termination. The product is currently obsolete, making identification of compatible substitute parts essential for system maintenance, repair, and component sourcing in legacy equipment applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB16KKG01 is determined by strict alignment of the following critical parameters:

Circuit configuration must remain SPDT with On-On switch function to maintain electrical compatibility with existing circuit designs. Current and voltage ratings (0.4VA at 28V AC/DC) establish the electrical load capacity and must not be exceeded. Mounting type (Panel Mount, Snap-In) and panel cutout dimensions determine physical fit within the enclosure. Operating temperature range (-25°C to 70°C) and mechanical/electrical life ratings (100,000 cycles minimum) define performance durability requirements. Compliance certifications (ROHS3, REACH Unaffected, EAR99) ensure regulatory alignment.

The YB16KKG01 qualifies as a substitute part based on matching circuit configuration, voltage/current ratings, mounting type, operating temperature range, and compliance status. Differences in termination style, panel cutout diameter, mechanical life rating, and product status are noted for engineering evaluation.

Parameter Comparison

Engineering Selection Recommendations

The YB16KKG01 is electrically compatible with the KB16KKG01 based on matching circuit configuration, voltage/current ratings, and operating temperature specifications. Both components maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for equivalent component selection.

Physical integration requires evaluation of panel cutout diameter differences: the KB16KKG01 requires a 12.30mm circular cutout, while the YB16KKG01 requires 16.00mm. Existing panel mounting holes must accommodate the larger diameter, or mechanical modification of the enclosure is necessary.

Termination compatibility must be assessed: the KB16KKG01 uses solder lug termination, while the YB16KKG01 provides solder and quick connect (0.110" / 2.8mm) options. Circuit board or wiring harness modifications may be required to accommodate the different termination style.

The YB16KKG01 offers extended mechanical life (200,000 cycles versus 100,000 cycles), providing improved durability in high-cycle applications. Active product status ensures ongoing availability and supply chain continuity compared to the obsolete KB16KKG01.

Frequently Asked Questions (FAQ)

Q: Can the YB16KKG01 directly replace the KB16KKG01 without modifications?

A: Electrical substitution is valid based on matching SPDT circuit, 0.4VA/28V ratings, and operating temperature range. Physical installation requires panel cutout enlargement from 12.30mm to 16.00mm diameter. Termination style differences (solder lug versus solder/quick connect) necessitate circuit board or harness adaptation.

Q: What are the critical parameters that define substitution eligibility?

A: Circuit configuration (SPDT), switch function (On-On), current rating (0.4VA AC/DC), voltage rating (28V AC/DC), mounting type (Panel Mount, Snap-In), operating temperature range (-25°C to 70°C), and electrical life (100,000 cycles minimum) establish substitution criteria. Compliance certifications (ROHS3, REACH Unaffected) must align.

Q: Does the larger panel cutout diameter of the YB16KKG01 affect electrical performance?

A: Panel cutout diameter is a mechanical specification that does not affect electrical performance. The difference reflects physical packaging design and does not alter circuit behavior, voltage/current ratings, or switching characteristics.

Q: Is the extended mechanical life of the YB16KKG01 (200,000 cycles) a requirement for substitution?

A: No. The KB16KKG01 specifies 100,000 mechanical cycles as the design requirement. The YB16KKG01 exceeds this specification, providing enhanced durability but not required for functional equivalence. Applications with lower cycle counts remain compatible.

Q: What compliance certifications apply to both parts?

A: Both KB16KKG01 and YB16KKG01 are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. Regulatory requirements are satisfied by either component.
