KB15SKW01 Equivalent & Substitute Parts

Part Overview

The KB15SKW01 is a pushbutton switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) circuit configuration with a 1A current rating at 125V AC. This component is designed for standard panel mount applications with front-facing actuator orientation and solder lug termination. The product is currently obsolete, making identification of functionally equivalent alternatives necessary for ongoing maintenance, repair, and legacy system support.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB15SKW01 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Circuit Configuration: SPDT
• Switch Function: On-Mom (Momentary)
• Voltage Rating - AC: 125V
• Voltage Rating - DC: 30V
• Mounting Type: Panel Mount, Front
• Actuator Type: Plunger for Cap
• Operating Temperature Range: -25°C ~ 70°C
• RoHS Compliance: ROHS3 Compliant

Allowable Variation Parameters:

• Current Rating: May exceed 1A (higher current rating is acceptable for lower-current applications)
• Mechanical Life: May exceed 100,000 cycles
• Electrical Life: May exceed 50,000 cycles
• Termination Style: Alternative termination methods acceptable if electrical connection is maintained
• Panel Cutout Dimensions: Larger cutout diameter acceptable with mechanical adaptation

The YB15SKW01 qualifies as a substitute part based on matching all mandatory parameters while exceeding performance specifications in current rating (3A), mechanical life (1,000,000 cycles), and electrical life (100,000 cycles).

Parameter Comparison

Engineering Selection Recommendations

The YB15SKW01 is the designated substitute for the obsolete KB15SKW01. Both components maintain identical electrical specifications for voltage and circuit configuration, ensuring functional compatibility in SPDT momentary switch applications rated for 125V AC operation.

The YB15SKW01 offers enhanced reliability through superior mechanical and electrical life ratings, providing extended service intervals in legacy system replacements. Both parts maintain ROHS3 compliance and unlimited moisture sensitivity level (MSL 1), meeting current environmental and regulatory standards.

Panel cutout diameter increases from 12.30mm to 16.00mm on the substitute part. Mechanical adaptation of the panel mounting interface is required during installation. Termination style modification from solder lug to solder with quick connect option necessitates corresponding circuit board or harness reconfiguration.

Frequently Asked Questions (FAQ)

Q: Can the YB15SKW01 directly replace the KB15SKW01 without modification?

A: Electrical substitution is direct. Mechanical and termination modifications are required. The larger 16.00mm panel cutout requires panel drilling adjustment. The quick connect termination requires harness or circuit board adaptation from the original solder lug configuration.

Q: What is the significance of the higher current rating on the YB15SKW01?

A: The 3A rating on the YB15SKW01 exceeds the 1A requirement of the KB15SKW01. This higher rating does not affect compatibility in 1A applications and provides additional design margin for circuit protection and component longevity.

Q: Are both parts compliant with current environmental regulations?

A: Both KB15SKW01 and YB15SKW01 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and use.

Q: What is the impact of the increased mechanical life specification?

A: The YB15SKW01 mechanical life rating of 1,000,000 cycles compared to 100,000 cycles on the KB15SKW01 indicates enhanced durability. This specification reflects improved component design and material selection, extending service life in repetitive switching applications.

Q: Does the quick connect termination affect electrical performance?

A: Quick connect termination (0.110" / 2.8mm) maintains equivalent electrical performance to solder lug termination. Connection method differs, requiring harness or board-level reconfiguration during installation.

Q: Is the YB15SKW01 available in the same packaging as the KB15SKW01?

A: The YB15SKW01 is supplied in tray packaging. Original KB15SKW01 packaging specification was not provided. Verify packaging requirements for your application and procurement process.
