KB15RKG01-6G-JB Equivalent & Substitute Parts

Part Overview

The KB15RKG01-6G-JB is a pushbutton switch manufactured by NKK Switches, classified as SPDT (Single Pole Double Throw) with 0.4VA rating at 28V. This illuminated panel mount switch features a rectangular button actuator with blue LED illumination and solder lug termination. The product is currently obsolete, making identification of compatible substitute parts essential for system maintenance, repair, and redesign applications where continued functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB15RKG01-6G-JB is determined by strict alignment with the following electrical and mechanical parameters:

Critical Matching Parameters:

• Circuit configuration (SPDT)
• Switch function (On-Mom momentary operation)
• Current and voltage ratings (0.4VA at 28V AC/DC)
• Illumination type and color (LED, Blue)
• Illumination voltage (3.6 VDC nominal)
• Operating temperature range (-25°C to 50°C)
• Mounting type (Panel Mount, Front)
• RoHS compliance status (ROHS3)

The YB15RKG01-6G-JB meets all critical electrical parameters and maintains functional equivalence. Differences in panel cutout dimensions, termination style, and mechanical life cycles represent design variations within the same functional category and do not prevent substitution in applications where the electrical and operational requirements are identical.

Parameter Comparison

Engineering Selection Recommendations

The YB15RKG01-6G-JB is a direct functional equivalent for KB15RKG01-6G-JB applications. Both components are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The YB15RKG01-6G-JB carries active product status, ensuring ongoing availability and supply chain continuity compared to the obsolete KB15RKG01-6G-JB.

Electrical performance is identical across all critical parameters: SPDT circuit, 0.4VA at 28V (AC/DC), momentary operation, and 3.6 VDC blue LED illumination. Both components operate within the same temperature range (-25°C to 50°C) and maintain equivalent functional reliability for the specified electrical load.

Design differences exist in termination style (solder lug versus solder with quick connect option), panel cutout diameter (12.30mm versus 16.00mm), and mechanical life rating (100,000 versus 1,000,000 cycles). These variations require verification against specific installation constraints and panel geometry before implementation.

Frequently Asked Questions (FAQ)

Q: Can YB15RKG01-6G-JB replace KB15RKG01-6G-JB in existing applications?

A: Yes, provided that panel cutout dimensions and termination style are compatible with the existing installation. The YB15RKG01-6G-JB requires a 16.00mm circular cutout compared to the KB15RKG01-6G-JB's 12.30mm cutout. Termination differences (quick connect option on YB series) must be evaluated against circuit board or harness connection requirements.

Q: What are the electrical compatibility requirements?

A: Both components are electrically identical: SPDT configuration, 0.4VA at 28V (AC/DC), momentary operation, and 3.6 VDC blue LED illumination. No circuit modifications are required for electrical substitution.

Q: Does the higher mechanical life rating of YB15RKG01-6G-JB affect compatibility?

A: No. The 1,000,000-cycle mechanical life of the YB15RKG01-6G-JB exceeds the 100,000-cycle rating of the KB15RKG01-6G-JB, providing enhanced durability without affecting functional compatibility.

Q: Are there regulatory compliance differences?

A: Both components are ROHS3 compliant and REACH unaffected. No compliance barriers exist for substitution.

Q: What is the primary consideration for panel integration?

A: Panel cutout diameter is the critical mechanical constraint. The YB15RKG01-6G-JB requires a 16.00mm circular opening versus the KB15RKG01-6G-JB's 12.30mm opening. Panel modification may be necessary if the existing cutout cannot accommodate the larger diameter.
