LB15CKG01-5F-JB Equivalent & Substitute Parts

Part Overview

The LB15CKG01-5F-JB is an illuminated pushbutton switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) circuit configuration with 0.4VA current rating at 28V. This panel-mount, snap-in switch is designed for applications requiring momentary operation with integrated LED illumination. The part is currently active in production with 954 units in stock. Substitute parts are identified when equivalent electrical and mechanical specifications are required due to inventory constraints, application-specific illumination color requirements, or design modifications that do not compromise core functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LB15CKG01-5F-JB is determined by strict equivalence across the following critical parameters:

• Circuit configuration (SPDT)
• Switch function (On-Mom momentary operation)
• Current and voltage ratings (0.4VA at 28V AC/DC)
• Mounting type and panel cutout dimensions (Panel Mount, Snap-In, 22.00mm circular)
• Termination style (Solder, Quick Connect - 0.110")
• Operating temperature range (-25°C to 50°C)
• Mechanical and electrical life ratings (1,000,000 and 100,000 cycles respectively)
• Base product number (LB15CKG)
• Compliance certifications (ROHS3, REACH Unaffected)

The substitute part LB15CKG01-5C-JC meets all these criteria. The only permitted variation is the illumination color (LED Green vs. LED Red) and corresponding illumination voltage (2.1 VDC vs. 1.9 VDC), which does not affect electrical or mechanical compatibility when the application design accommodates the alternative indicator color.

Parameter Comparison

Engineering Selection Recommendations

Both the LB15CKG01-5F-JB and LB15CKG01-5C-JC are active production parts with full ROHS3 compliance and REACH unaffected status, ensuring regulatory compliance for current and future applications. Selection between these parts depends solely on illumination color requirements within the application design. The LB15CKG01-5F-JB provides green LED indication at 2.1 VDC nominal, while the LB15CKG01-5C-JC provides red LED indication at 1.9 VDC nominal. Both parts share identical electrical switching characteristics, mechanical durability ratings, and panel mounting specifications. Component selection should be based on the specific indicator color requirement of the end application and current inventory availability.

Frequently Asked Questions (FAQ)

Q: Can LB15CKG01-5C-JC be used as a direct replacement for LB15CKG01-5F-JB?

A: Yes, provided the application design accommodates red LED illumination instead of green. All electrical, mechanical, and mounting specifications are identical. The illumination voltage difference (1.9 VDC vs. 2.1 VDC) is within normal operating tolerances for LED indicator circuits.

Q: Are there any panel cutout or mounting modifications required when substituting between these parts?

A: No. Both parts feature identical panel mount, snap-in configuration with a 22.00mm circular cutout diameter. No mechanical modifications to the panel assembly are required.

Q: What is the difference in illumination voltage between the two parts?

A: The LB15CKG01-5F-JB operates at 2.1 VDC nominal for green LED illumination, while the LB15CKG01-5C-JC operates at 1.9 VDC nominal for red LED illumination. This difference reflects the inherent forward voltage characteristics of the respective LED colors and does not affect switch functionality.

Q: Do both parts meet the same compliance and regulatory standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and carry identical ECCN (EAR99) and HTSUS (8536.50.9031) classifications.

Q: What is the mechanical and electrical life expectancy for both parts?

A: Both parts are rated for 1,000,000 mechanical cycles and 100,000 electrical cycles under specified operating conditions within the -25°C to 50°C temperature range.

Q: Are the termination styles identical between the two parts?

A: Yes. Both parts use solder and quick connect termination with 0.110" (2.8mm) connector spacing, ensuring compatibility with existing PCB layouts and harness assemblies.
