JB15LPC-BE Equivalent & Substitute Parts

Part Overview

The JB15LPC-BE is an illuminated tactile switch manufactured by NKK Switches, designed for applications requiring momentary contact switching at 24VDC with 0.05A contact rating. This SPST-NO (Single Pole Single Throw - Normally Open) switch features a red LED illumination, top-actuated square button design, and IP67 ingress protection rating. The component is actively produced and maintains ROHS3 compliance with unlimited moisture sensitivity level (MSL 1).

Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and regulatory compliance can be maintained across different manufacturers while accommodating application-specific requirements such as packaging format, inventory availability, or design constraints.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the JB15LPC-BE is determined by the following critical parameters:

Electrical Compatibility: Circuit configuration (SPST-NO), contact rating (0.05A @ 24VDC), and switch function (momentary) must be identical.

Mechanical Compatibility: Mounting type (through hole), termination style (PC pin), and actuator orientation (top actuated) must match to ensure PCB integration without redesign.

Environmental & Regulatory: RoHS3 compliance and REACH unaffected status are mandatory for equivalent substitution.

Functional Differences Permitting Substitution: Variations in actuator height (within mechanical envelope constraints), outline dimensions, operating temperature range, and mechanical life cycle rating are acceptable when the application does not explicitly require the original specifications. Illumination type differences (illuminated vs. non-illuminated) represent functional variations that require application assessment.

The FSM102 (TE Connectivity ALCOSWITCH Switches) meets the core electrical and mechanical substitution criteria but introduces the following parameter deviations: non-illuminated design, larger outline (12.00mm x 12.00mm), increased actuator height (12.00mm), reduced mechanical life (100,000 cycles), and extended operating temperature range (-35°C ~ 85°C).

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (JB15LPC-BE): Maintain original specification when illuminated feedback is required, mechanical life exceeds 5,000,000 cycles is specified, compact footprint (10.00mm x 10.00mm) is constrained, or operating temperature range -25°C ~ 70°C is required. Product status is active with established supply chain.

Substitute Selection (FSM102): The FSM102 is suitable for applications where illumination is not required, operating temperature range can extend to -35°C ~ 85°C, and mechanical life requirement does not exceed 100,000 cycles. The larger outline (12.00mm x 12.00mm) and increased actuator height (12.00mm) require PCB layout verification. Both components maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for equivalent substitution.

Inventory Consideration: FSM102 maintains higher stock availability (13,359 pcs) compared to JB15LPC-BE (890 pcs), which may influence procurement decisions for high-volume applications.

Frequently Asked Questions (FAQ)

Q: Can FSM102 replace JB15LPC-BE in an illuminated panel design?

A: No. The FSM102 is non-illuminated, while the JB15LPC-BE includes red LED illumination at 1.8VDC. Applications requiring visual feedback through illumination must use the JB15LPC-BE or identify an alternative illuminated substitute.

Q: Are the mechanical life ratings interchangeable?

A: No. The JB15LPC-BE is rated for 5,000,000 mechanical cycles, while FSM102 is rated for 100,000 cycles. Applications with cycle life requirements exceeding 100,000 operations must use the JB15LPC-BE.

Q: Will FSM102 fit the same PCB footprint as JB15LPC-BE?

A: Partial compatibility exists. Both components use through-hole PC pin termination and top-actuated orientation. However, FSM102 has a larger outline (12.00mm x 12.00mm vs. 10.00mm x 10.00mm) and greater actuator height (12.00mm vs. 11.20mm). PCB layout and mechanical clearance must be verified before substitution.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both JB15LPC-BE and FSM102 are ROHS3 compliant and REACH unaffected, satisfying equivalent regulatory requirements for industrial and commercial applications.

Q: What is the operating force difference between these switches?

A: JB15LPC-BE requires 176gf operating force, while FSM102 requires 160gf. This 16gf difference is within typical tactile switch tolerance ranges and does not constitute a functional incompatibility for standard momentary switching applications.

Q: Can FSM102 operate in the full temperature range of JB15LPC-BE?

A: Yes. FSM102 operates across -35°C ~ 85°C, which encompasses the JB15LPC-BE range of -25°C ~ 70°C. FSM102 provides extended temperature capability for applications requiring operation below -25°C or above 70°C.
