JB15LPE-BE Equivalent & Substitute Parts

Part Overview

The JB15LPE-BE is an illuminated tactile switch manufactured by NKK Switches, designed for applications requiring SPST-NO (Single Pole Single Throw - Normally Open) momentary switching at 0.05A and 24VDC. This component features a square button actuator with top actuation, yellow LED illumination, and IP67 ingress protection for dust and water resistance. The product is currently active and widely available in inventory. Substitute parts may be required due to supply constraints, packaging preferences, or specific application requirements such as non-illuminated operation or different mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the JB15LPE-BE is determined by the following critical parameters:

Mandatory Matching Parameters:

• Circuit configuration: SPST-NO
• Switch function: Off-Mom (momentary operation)
• Contact rating: 0.05A @ 24VDC
• Mounting type: Through Hole
• Actuator orientation: Top Actuated
• Termination style: PC Pin

Allowable Variation Parameters:

• Actuator type (Square Button vs. Plunger for Cap)
• Actuator height off PCB (11.20mm vs. 12.00mm)
• Outline dimensions (10.00mm x 10.00mm vs. 12.00mm x 12.00mm)
• Illumination (Illuminated vs. Non-Illuminated)
• Operating force (176gf vs. 160gf)
• Switch travel (0.25mm vs. 0.30mm)
• Operating temperature range (-25°C ~ 70°C vs. -35°C ~ 85°C)
• Mechanical life (5,000,000 Cycles vs. 100,000 Cycles)
• Packaging format (Tray vs. Bulk)

The FSM102 qualifies as a substitute part because it maintains the core electrical and mechanical switching characteristics while offering different physical and operational attributes suitable for alternative design requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the JB15LPE-BE and FSM102 are active products with ROHS3 compliance and REACH unaffected status, making them suitable for current design implementations. Selection between these parts should be based on specific application requirements:

Select JB15LPE-BE when:

• Yellow LED illumination is required for user interface feedback
• Compact footprint (10.00mm x 10.00mm) is necessary
• Extended mechanical life (5,000,000 cycles) is critical
• Lower operating force (176gf) is preferred
• Tray packaging is required for assembly processes

Select FSM102 when:

• Non-illuminated operation is acceptable or preferred
• Larger footprint (12.00mm x 12.00mm) accommodates design constraints
• Extended temperature range (-35°C ~ 85°C) is required
• Bulk packaging is suitable for procurement workflows
• Lower operating force (160gf) is advantageous

Both parts maintain identical electrical switching characteristics and are suitable for 24VDC, 0.05A applications with momentary operation requirements.

Frequently Asked Questions (FAQ)

Q: Can FSM102 replace JB15LPE-BE in an existing design?

A: FSM102 can replace JB15LPE-BE if the design does not depend on yellow LED illumination. The core switching function is identical. However, the larger outline dimensions (12.00mm x 12.00mm vs. 10.00mm x 10.00mm) and different actuator type (Plunger for Cap vs. Square Button) may require PCB layout modifications and mechanical housing adjustments.

Q: What are the key electrical compatibility factors?

A: Both parts are fully compatible electrically. They share identical circuit configuration (SPST-NO), switch function (Off-Mom), contact rating (0.05A @ 24VDC), and termination style (PC Pin). Electrical substitution is direct.

Q: How do the mechanical specifications differ?

A: JB15LPE-BE features a square button actuator with 11.20mm height and 0.25mm travel, while FSM102 uses a plunger actuator with 12.00mm height and 0.30mm travel. Operating force differs slightly (176gf vs. 160gf). These differences may affect user interface feel and PCB clearance requirements.

Q: What is the impact of different mechanical life ratings?

A: JB15LPE-BE is rated for 5,000,000 cycles compared to FSM102's 100,000 cycles. For applications requiring frequent actuation over extended product lifespans, JB15LPE-BE provides significantly longer operational reliability.

Q: Are there temperature range considerations?

A: JB15LPE-BE operates from -25°C to 70°C, while FSM102 operates from -35°C to 85°C. FSM102 is suitable for applications requiring extended low-temperature or high-temperature operation beyond JB15LPE-BE's range.

Q: How do packaging formats affect procurement?

A: JB15LPE-BE is supplied in Tray packaging, suitable for automated assembly processes. FSM102 is supplied in Bulk packaging, which may require additional handling and sorting for assembly operations. Packaging selection depends on manufacturing workflow requirements.
