JB15LPC-BF Equivalent & Substitute Parts

Part Overview

The JB15LPC-BF is an illuminated tactile switch manufactured by NKK Switches, designed for applications requiring momentary contact switching at 0.05A and 24VDC. This SPST-NO (Single Pole Single Throw - Normally Open) switch features a square button actuator with red LED illumination and IP67 ingress protection, making it suitable for sealed and waterproof applications. The part is currently active in production with 1079 units in stock. Substitute parts may be required due to inventory constraints, application-specific mechanical requirements, or design optimization needs.

Key Parameters

Substitute Part Grouping Explanation

The FSM102 manufactured by TE Connectivity ALCOSWITCH Switches is identified as a substitute for the JB15LPC-BF based on the following critical parameters:

Matching Parameters:

• Circuit configuration: SPST-NO
• Contact rating: 0.05A @ 24VDC
• Switch function: Off-Mom (Momentary)
• Mounting type: Through Hole
• Actuator orientation: Top Actuated
• Termination style: PC Pin
• RoHS compliance: ROHS3 Compliant
• REACH status: REACH Unaffected
• ECCN classification: EAR99

Substitution Basis: The FSM102 maintains electrical equivalence through identical circuit topology, contact rating, and switching function. Both parts are through-hole mounted with top-actuated designs and compatible termination styles. Compliance certifications align across RoHS3 and REACH standards, ensuring regulatory compatibility in equivalent applications.

Parameter Comparison

Engineering Selection Recommendations

Both the JB15LPC-BF and FSM102 are active production parts with ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility for equivalent applications. The JB15LPC-BF is recommended for applications requiring integrated red LED illumination at 1.8VDC, higher mechanical cycle life (5,000,000 cycles), and IP67 ingress protection. The FSM102 is suitable for applications where illumination is not required and where the extended operating temperature range (-35°C to 85°C) provides additional thermal margin. Selection should be based on specific application requirements regarding illumination, mechanical life expectations, and environmental operating conditions.

Frequently Asked Questions (FAQ)

Q: Can FSM102 replace JB15LPC-BF in all applications?

A: FSM102 provides electrical equivalence for the core switching function (SPST-NO, 0.05A @ 24VDC, momentary operation). However, FSM102 lacks the integrated red LED illumination present in JB15LPC-BF. Applications requiring visual feedback through LED indication must retain the JB15LPC-BF or source an alternative illuminated switch.

Q: What are the mechanical differences between these parts?

A: JB15LPC-BF has a 10.00mm x 10.00mm outline with 11.20mm actuator height and 0.25mm switch travel. FSM102 has a larger 12.00mm x 12.00mm outline with 12.00mm actuator height and 0.30mm switch travel. These dimensional differences may affect PCB layout compatibility and mechanical clearance requirements.

Q: How do mechanical life ratings compare?

A: JB15LPC-BF is rated for 5,000,000 mechanical cycles, while FSM102 is rated for 100,000 cycles. Applications with high-cycle switching requirements should prioritize JB15LPC-BF to ensure adequate component longevity.

Q: Are there temperature range considerations?

A: JB15LPC-BF operates from -25°C to 70°C, while FSM102 operates from -35°C to 85°C. FSM102 provides extended low-temperature and high-temperature capability, making it suitable for applications with broader thermal requirements.

Q: What packaging differences exist?

A: JB15LPC-BF is supplied in Box packaging, while FSM102 is supplied in Bulk packaging. Packaging selection may affect inventory management and component handling procedures.
