JB15LPB Equivalent & Substitute Parts

Part Overview

The JB15LPB is a tactile switch manufactured by NKK Switches, configured as a SPST-NO (Single Pole Single Throw - Normally Open) momentary contact switch. It features top actuation, through-hole mounting, and illumination with a white LED. The switch is rated for 0.05A at 24VDC and is sealed to IP67 specifications for dust and water resistance.

The JB15LPB has been discontinued at DiGi Electronics. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the JB15LPB is determined by the following critical parameters:

• Circuit configuration (SPST-NO)
• Switch function (Off-Mom momentary operation)
• Contact rating (0.05A @ 24VDC)
• Mounting type (Through Hole)
• Actuator orientation (Top Actuated)
• Physical outline (10.00mm x 10.00mm)
• Operating force (176gf)
• Switch travel (0.25mm)
• Mechanical life (5,000,000 cycles)
• Ingress protection (IP67)
• Operating temperature range (-25°C to 70°C)
• Termination style (PC Pin)

The JB15LPE qualifies as a direct substitute because it maintains identical electrical specifications, mechanical dimensions, actuator characteristics, and environmental ratings. The primary difference is the illumination color (yellow LED versus white LED) and illumination voltage specification (2VDC nominal for JB15LPE versus unspecified for JB15LPB). Both parts are from the same JB series and share the same core functionality and physical form factor.

Parameter Comparison

Engineering Selection Recommendations

The JB15LPE is a qualified substitute for the JB15LPB based on electrical and mechanical equivalence. Both parts maintain identical contact ratings, circuit configurations, mechanical characteristics, and environmental sealing specifications. Both are ROHS3 compliant and operate within the same temperature range.

The JB15LPE offers the advantage of active product status, ensuring continued availability and supply chain reliability. The JB15LPB is discontinued, making the JB15LPE the preferred selection for new designs and ongoing production requirements.

The illumination color difference (white versus yellow) and illumination voltage specification (2VDC for JB15LPE) should be evaluated against application-specific visual indication requirements. If white LED illumination is a critical design requirement, alternative parts from the JB series with white LED specifications should be consulted.

Frequently Asked Questions (FAQ)

Q: Can the JB15LPE directly replace the JB15LPB in existing designs?

A: Yes. The JB15LPE maintains identical electrical ratings (0.05A @ 24VDC), circuit configuration (SPST-NO), mechanical dimensions (10.00mm x 10.00mm), actuator characteristics (176gf operating force, 0.25mm travel), and environmental specifications (IP67). Both use PC Pin termination and through-hole mounting. The parts are mechanically and electrically interchangeable.

Q: What is the primary difference between these parts?

A: The illumination color differs: JB15LPB uses white LED illumination, while JB15LPE uses yellow LED illumination. The JB15LPE also specifies 2VDC nominal illumination voltage. Additionally, the JB15LPE is currently active in production, while the JB15LPB is discontinued.

Q: Are there packaging differences?

A: The JB15LPB packaging specification is not provided in the available data. The JB15LPE is supplied in Tray packaging. Packaging differences do not affect electrical or mechanical compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the JB15LPB and JB15LPE are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 and HTSUS 8536.50.9031. Both carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: Which part should be selected for new production?

A: The JB15LPE should be selected for new production due to its active product status and guaranteed availability. The JB15LPB is discontinued and should not be specified for new designs.
