KB25CKW01-5C05-JC Equivalent & Substitute Parts

Part Overview

The KB25CKW01-5C05-JC is a pushbutton switch manufactured by NKK Switches, featuring DPDT (Double Pole Double Throw) circuitry with illuminated panel mount design. This component operates at 1A (AC/DC) with 125V AC and 30V DC voltage ratings, incorporating red LED illumination at 5VDC nominal. The product is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations where this series is no longer available.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the KB25CKW01-5C05-JC is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Circuit configuration (DPDT)
• Switch function (On-Mom)
• Mounting type (Panel Mount, Front)
• Voltage ratings (125V AC / 30V DC minimum)
• Illumination type and color (LED, Red)
• Operating temperature range (-25°C to 50°C)
• Termination compatibility with solder lug connections
• RoHS3 compliance

Allowable Variations:

• Current rating may exceed 1A (higher ratings provide design margin)
• Mechanical and electrical life cycles may exceed specified minimums
• Panel cutout diameter may differ if mechanical redesign is acceptable
• Illumination voltage may differ if power supply adjustment is feasible
• Termination style may include additional options (Quick Connect) if wiring harness modification is permissible

The YB25CKW01-5C05-JC qualifies as a substitute based on matching circuit, function, mounting, voltage ratings, illumination type, temperature range, and compliance status, despite variations in current rating, life cycles, panel cutout, illumination voltage, and termination options.

Parameter Comparison

Engineering Selection Recommendations

The YB25CKW01-5C05-JC is suitable as a substitute for the obsolete KB25CKW01-5C05-JC based on the following engineering criteria:

Compliance and Availability: The substitute maintains active product status with NKK Switches, ensuring continued availability and supply chain reliability. Both components are ROHS3 compliant and carry identical moisture sensitivity ratings (MSL 1 - Unlimited), supporting equivalent environmental performance.

Electrical Compatibility: Both switches maintain identical voltage ratings (125V AC / 30V DC) and circuit configuration (DPDT On-Mom), ensuring functional equivalence in standard applications. The substitute's higher current rating (3A versus 1A) provides additional design margin without compromising performance in applications rated for 1A operation.

Mechanical Considerations: The substitute exhibits superior mechanical and electrical life cycles (1,000,000 and 100,000 cycles respectively versus 100,000 and 50,000 cycles), extending component longevity. However, the panel cutout diameter increases from 12.30mm to 16.00mm, requiring mechanical redesign of panel mounting fixtures.

Integration Factors: The illumination voltage differs (1.9VDC versus 5VDC), necessitating power supply adjustment or LED circuit modification. Termination style expansion to include Quick Connect options provides flexibility but requires wiring harness evaluation.

Frequently Asked Questions (FAQ)

Q: Can the YB25CKW01-5C05-JC directly replace the KB25CKW01-5C05-JC without modifications?

A: Direct replacement is not possible without modifications. The panel cutout diameter differs (16.00mm versus 12.30mm), requiring panel redesign. The illumination voltage differs (1.9VDC versus 5VDC), requiring power supply adjustment. Termination style options differ, requiring wiring harness evaluation.

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

A: Substitution eligibility is determined by matching circuit configuration (DPDT), switch function (On-Mom), mounting type (Panel Mount, Front), voltage ratings (125V AC / 30V DC minimum), illumination type and color (LED, Red), operating temperature range (-25°C to 50°C), and compliance status (ROHS3).

Q: Does the higher current rating of the substitute affect compatibility?

A: No. The substitute's 3A current rating exceeds the original 1A specification, providing design margin. Applications rated for 1A operation remain fully compatible, as the substitute can safely handle lower current loads.

Q: What impact does the illumination voltage difference have?

A: The substitute operates at 1.9VDC nominal illumination voltage versus the original 5VDC. This requires adjustment of the LED power supply circuit or modification of current-limiting resistor values to maintain proper illumination intensity and component longevity.

Q: Are there inventory considerations for this substitution?

A: The KB25CKW01-5C05-JC is obsolete with 957 pieces in stock. The YB25CKW01-5C05-JC is active with 776 pieces available. For long-term supply assurance, the active substitute is preferable.
