JB15LPB-JB Equivalent & Substitute Parts

Part Overview

The JB15LPB-JB 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 switch is currently discontinued at DiGi Electronics, making identification of equivalent substitute parts essential for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the JB15LPB-JB 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 vertical), actuator orientation (top actuated), termination style (PC pin), outline dimensions (10.00mm x 10.00mm), operating force (176gf), ingress protection (IP67), operating temperature range (-25°C ~ 70°C), actuator material (polyacetal), switch travel (0.25mm), and mechanical life (5,000,000 cycles).

The JB15LPE-JB qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. Variations in illumination color (white vs. yellow LED) and illumination voltage specification do not affect core switch functionality and are acceptable substitution criteria within the JB series.

Parameter Comparison

Engineering Selection Recommendations

The JB15LPE-JB is the qualified substitute for the discontinued JB15LPB-JB. Both parts maintain identical electrical specifications, mechanical dimensions, and environmental ratings. The JB15LPE-JB carries active product status, ensuring ongoing availability and supply chain continuity. Both parts meet ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for industrial and commercial applications. The substitution is electrically and mechanically transparent, requiring no circuit redesign or PCB layout modification.

Frequently Asked Questions (FAQ)

Q: Can the JB15LPE-JB replace the JB15LPB-JB without PCB modifications?

A: Yes. Both parts share identical mechanical dimensions (10.00mm x 10.00mm outline, 11.20mm actuator height), through-hole PC pin termination, and electrical ratings (0.05A @ 24VDC, SPST-NO configuration). Direct substitution on existing PCBs is supported.

Q: What is the difference between the JB15LPB-JB and JB15LPE-JB?

A: The primary difference is illumination color: JB15LPB-JB uses white LED illumination, while JB15LPE-JB uses yellow LED illumination. The JB15LPE-JB specifies 2VDC illumination voltage. All other electrical and mechanical parameters are identical. Product status differs: JB15LPB-JB is discontinued; JB15LPE-JB is active.

Q: Are there packaging differences between these parts?

A: The JB15LPB-JB is supplied in standard packaging, while the JB15LPE-JB is supplied in bulk packaging. This does not affect component functionality or electrical performance.

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

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and rated for IP67 ingress protection (dust tight, waterproof). Both operate across -25°C to 70°C and support 5,000,000 mechanical cycles.

Q: Is the JB15LPE-JB suitable for applications requiring white illumination?

A: No. If white LED illumination is a functional requirement, the JB15LPE-JB (yellow LED) is not suitable. Alternative white-illuminated switches within the JB series should be evaluated.
