JB15LPB-B Equivalent & Substitute Parts

Part Overview

The JB15LPB-B is a tactile switch manufactured by NKK Switches, classified as SPST-NO (Single Pole Single Throw - Normally Open) with a contact rating of 0.05A at 24VDC. This illuminated pushbutton switch features a square button actuator, top-mounted orientation, and through-hole termination suitable for PCB integration. The part is currently discontinued at DiGi Electronics, making identification of equivalent alternatives necessary for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the JB15LPB-B is determined by strict equivalence across the following critical parameters:

Circuit configuration (SPST-NO), switch function (Off-Mom momentary operation), contact rating (0.05A @ 24VDC), actuator type (square button), mounting method (through hole), actuator height (11.20mm), actuator orientation (top actuated), termination style (PC pin), outline dimensions (10.00mm x 10.00mm), operating force (176gf), ingress protection rating (IP67), operating temperature range (-25°C ~ 70°C), actuator material (polyacetal), switch travel (0.25mm), and mechanical life (5,000,000 cycles).

Acceptable variations are limited to illumination color and illumination voltage specifications, as these do not affect core electrical or mechanical functionality. All substitute parts must maintain ROHS3 compliance and MSL 1 rating.

Parameter Comparison

Engineering Selection Recommendations

The JB15LPE-JB serves as a direct functional equivalent to the discontinued JB15LPB-B. Both parts maintain identical electrical and mechanical specifications across all critical parameters including circuit configuration, contact rating, actuator geometry, and environmental protection rating.

The primary distinction between these parts is the illumination color (white versus yellow) and the specified illumination voltage for the substitute (2 VDC). These differences do not affect core switch operation or PCB compatibility. Both parts carry ROHS3 compliance and MSL 1 rating, ensuring regulatory and environmental compatibility.

The JB15LPE-JB is currently in active production status, providing supply continuity for applications previously utilizing the JB15LPB-B. Selection of the substitute part is appropriate for new designs and replacement applications where the illumination color change is acceptable within the system design constraints.

Frequently Asked Questions (FAQ)

Q: Can the JB15LPE-JB replace the JB15LPB-B in existing designs?

A: Yes. The JB15LPE-JB is electrically and mechanically equivalent to the JB15LPB-B across all functional parameters. The only difference is illumination color (yellow versus white) and specified illumination voltage. PCB layout, mounting footprint, and electrical performance remain identical.

Q: What is the difference in illumination between these parts?

A: The JB15LPB-B uses white LED illumination with unspecified voltage. The JB15LPE-JB uses yellow LED illumination at 2 VDC nominal. The illumination color change may affect visual indication in the application but does not impact switch electrical characteristics.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the JB15LPB-B and JB15LPE-JB are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and use.

Q: What is the packaging difference?

A: The JB15LPB-B is supplied in standard packaging. The JB15LPE-JB is supplied in bulk packaging. Both parts are identical in component specification; packaging format does not affect electrical or mechanical performance.

Q: Why is the JB15LPB-B discontinued?

A: The JB15LPB-B is discontinued at DiGi Electronics. The JB15LPE-JB remains in active production and provides equivalent functionality for ongoing applications.
