JB15KP-4HC Equivalent & Substitute Parts

Part Overview

The JB15KP-4HC is an active SPST-NO tactile switch manufactured by NKK Switches, designed for momentary operation at 0.05A and 24VDC. This through-hole mounted component features a square button actuator with IP67 ingress protection and process sealing, making it suitable for applications requiring dust and water resistance. The part is RoHS3 compliant and REACH unaffected, with unlimited moisture sensitivity rating (MSL 1). Finding equivalent or substitute parts may be necessary due to inventory constraints, lead time requirements, or design flexibility needs while maintaining functional compatibility.

Key Parameters

Substitute Part Grouping Explanation

The FSM102 by TE Connectivity ALCOSWITCH Switches qualifies as a functional substitute for the JB15KP-4HC based on the following critical parameters:

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
• RoHS3 compliance
• REACH unaffected status
• Active product status

Substitution Basis: Both parts share identical electrical specifications (circuit type, contact rating, voltage) and mechanical mounting characteristics (through-hole, top-actuated, PC pin termination). Both are actively manufactured, RoHS3 compliant, and suitable for applications requiring momentary switching at the specified voltage and current levels. The substitution is valid where the differences in outline dimensions, actuator height, operating force, and mechanical life do not conflict with application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the JB15KP-4HC and FSM102 are active products with RoHS3 compliance and REACH unaffected status, making either suitable for new designs and production environments. Selection between these parts should be based on application-specific requirements:

The JB15KP-4HC is the primary choice where IP67 ingress protection is required, mechanical life exceeding 5,000,000 cycles is specified, or the compact 10.00mm x 10.00mm footprint is necessary for space-constrained layouts.

The FSM102 is suitable as a substitute where the wider operating temperature range (-35°C ~ 85°C versus -25°C ~ 70°C) provides advantage, or where the larger 12.00mm x 12.00mm outline and slightly lower operating force (160gf versus 176gf) align with design parameters. However, the FSM102's mechanical life rating of 100,000 cycles is significantly lower than the JB15KP-4HC, and the absence of specified ingress protection should be evaluated against application environmental requirements.

Frequently Asked Questions (FAQ)

Q: Can FSM102 directly replace JB15KP-4HC in existing designs?

A: Electrical compatibility is confirmed (SPST-NO, 0.05A @ 24VDC, momentary operation). However, physical layout changes may be required due to differences in outline dimensions (12.00mm x 12.00mm versus 10.00mm x 10.00mm) and actuator height (12.00mm versus 11.20mm). PCB footprint and enclosure clearances must be verified before substitution.

Q: What are the critical differences between these parts?

A: The JB15KP-4HC offers IP67 ingress protection and 5,000,000 cycle mechanical life, while the FSM102 provides a wider operating temperature range (-35°C ~ 85°C) and larger physical dimensions. The FSM102's mechanical life is rated at 100,000 cycles, making it unsuitable for high-cycle applications.

Q: Are both parts suitable for moisture-exposed environments?

A: The JB15KP-4HC is specified with IP67 protection (dust tight, waterproof). The FSM102 does not have specified ingress protection ratings. For applications requiring environmental sealing, the JB15KP-4HC is the appropriate choice.

Q: What packaging differences exist between these parts?

A: The JB15KP-4HC is supplied in Box packaging, while the FSM102 is supplied in Bulk packaging. This affects inventory management and handling procedures but does not impact electrical or mechanical function.

Q: Which part has better long-term reliability for high-cycle applications?

A: The JB15KP-4HC is rated for 5,000,000 mechanical cycles compared to the FSM102's 100,000 cycles. For applications requiring extended operational life or frequent switching, the JB15KP-4HC is the specified choice.
