JB15LPF-BH Equivalent & Substitute Parts

Part Overview

The JB15LPF-BH is an illuminated tactile switch manufactured by NKK Switches, designed for SPST-NO (Single Pole Single Throw - Normally Open) applications. This momentary-contact switch operates at 0.05A @ 24VDC with a green LED illumination and is rated for IP67 ingress protection. The part is currently Active in product status and widely used in industrial control panels, instrumentation, and equipment requiring sealed, illuminated push-button interfaces. Substitute parts are identified when equivalent electrical ratings, mechanical compatibility, and functional characteristics align with application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the JB15LPF-BH is determined by the following critical parameters:

• Electrical Compatibility: Circuit configuration (SPST-NO), contact rating (0.05A @ 24VDC), and switch function (Off-Mom) must be identical
• Mechanical Compatibility: Mounting type (Through Hole), actuator orientation (Top Actuated), and termination style (PC Pin) must match
• Environmental Compliance: RoHS3 compliance and REACH Unaffected status are required for regulatory alignment
• Functional Tolerance: Operating temperature range, switch travel, and operating force may vary within acceptable engineering margins for the application

The FSM102 from TE Connectivity ALCOSWITCH Switches meets the core electrical and mechanical compatibility criteria as a substitute part.

Parameter Comparison

Engineering Selection Recommendations

Both the JB15LPF-BH and FSM102 are Active products with ROHS3 compliance and REACH Unaffected status, meeting current regulatory requirements. The FSM102 provides equivalent electrical performance at the specified 0.05A @ 24VDC contact rating and maintains identical circuit configuration and switch function.

Key considerations for substitution:

• The FSM102 operates across a wider temperature range (-35°C ~ 85°C versus -25°C ~ 70°C), providing extended environmental capability
• The JB15LPF-BH includes integrated green LED illumination; the FSM102 is non-illuminated and requires external illumination solutions if visual feedback is required
• The JB15LPF-BH is rated for IP67 ingress protection; the FSM102 ingress protection rating is not specified
• The JB15LPF-BH supports 5,000,000 mechanical cycles; the FSM102 supports 100,000 cycles, representing a significant difference in cycle life expectancy
• Operating force differs by 16gf (176gf versus 160gf) and switch travel by 0.05mm (0.25mm versus 0.30mm)

Selection should be based on application-specific requirements for illumination, environmental sealing, cycle life, and tactile feedback characteristics.

Frequently Asked Questions (FAQ)

Q: Can FSM102 directly replace JB15LPF-BH in all applications?

A: FSM102 provides electrical and mechanical compatibility for SPST-NO momentary switching at 0.05A @ 24VDC. However, applications requiring integrated LED illumination, IP67 sealing, or extended mechanical life (5,000,000 cycles) must evaluate whether the FSM102's non-illuminated design, unspecified ingress protection, and 100,000-cycle rating meet functional requirements.

Q: What are the key electrical parameters that must match for substitution?

A: Circuit configuration (SPST-NO), switch function (Off-Mom), and contact rating (0.05A @ 24VDC) must be identical. Both parts meet these criteria.

Q: Does the difference in operating force affect compatibility?

A: Operating force (176gf for JB15LPF-BH versus 160gf for FSM102) affects tactile feedback and actuation feel. Applications with specific force requirements or user interface standards should evaluate this 16gf difference.

Q: Are both parts compliant with current regulations?

A: Yes. Both JB15LPF-BH and FSM102 are ROHS3 Compliant and REACH Unaffected, meeting current regulatory standards.

Q: What is the significance of the mechanical life difference?

A: JB15LPF-BH is rated for 5,000,000 cycles while FSM102 is rated for 100,000 cycles. Applications with high-frequency actuation requirements should account for this 50-fold difference in rated mechanical life.

Q: Does packaging affect substitution eligibility?

A: Both parts use PC Pin termination and Through Hole mounting, ensuring PCB compatibility. JB15LPF-BH is supplied in Tray packaging; FSM102 is supplied in Bulk packaging. This does not affect electrical or mechanical substitution but may impact procurement and handling procedures.
