Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB25SKW01-5D24-JD is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Circuit configuration: DPDT
• Switch function: On-Momentary
• Mounting type: Panel Mount, Front
• Illumination type: LED, Amber
• Operating temperature range: -25°C to 50°C
• Voltage rating: 125V AC minimum, 30V DC minimum
• Termination compatibility with existing circuit board design

Allowable Variation Parameters:

• Current rating: May exceed 1A (higher ratings are backward compatible)
• Illumination voltage: Substitutes with different nominal voltages are acceptable if circuit design accommodates voltage adjustment
• Panel cutout diameter: Larger cutouts require mechanical redesign; smaller cutouts are not compatible
• Mechanical and electrical life: Higher cycle ratings provide enhanced reliability
• Termination style: Must be compatible with existing solder or connector infrastructure

The YB25SKW01-5D24-JD qualifies as a substitute based on matching circuit configuration, switch function, mounting type, illumination type, and operating temperature range. Differences in current rating, illumination voltage, panel cutout diameter, and termination style require engineering evaluation for specific applications.

Parameter Comparison

Engineering Selection Recommendations

The YB25SKW01-5D24-JD is an active product substitute for the obsolete KB25SKW01-5D24-JD. Selection of this substitute requires evaluation of the following factors:

Electrical Compatibility: The substitute provides higher current capacity (3A versus 1A), which is backward compatible with applications designed for the original 1A rating. Voltage ratings remain identical at 125V AC and 30V DC.

Illumination Voltage Consideration: The substitute operates at 2VDC nominal illumination voltage compared to the original 24VDC. Circuit redesign is required to accommodate this voltage difference. The lower voltage requirement may reduce power consumption in illumination circuits.

Mechanical Interface: The substitute requires a larger panel cutout diameter (16.00mm versus 12.30mm). Existing panel designs must be modified to accommodate this dimensional change.

Termination Interface: The substitute offers dual termination options (Solder and Quick Connect 0.110" / 2.8mm) compared to the original Solder Lug only. Circuit board design must accommodate the selected termination method.

Operational Durability: The substitute provides enhanced mechanical life (1,000,000 cycles versus 100,000 cycles) and electrical life (100,000 cycles versus 50,000 cycles), resulting in extended component reliability.

Compliance Status: Both components maintain MSL 1 (Unlimited) moisture sensitivity rating. RoHS3 compliance is confirmed for the original part; compliance status for the substitute should be verified with the manufacturer.

Frequently Asked Questions (FAQ)

Q: Can the YB25SKW01-5D24-JD be used as a direct replacement without circuit modification?

A: No. The substitute differs in illumination voltage (2VDC versus 24VDC), panel cutout diameter (16.00mm versus 12.30mm), and termination options. Circuit redesign and mechanical panel modification are required.

Q: What is the impact of the higher current rating (3A versus 1A) on system design?

A: The higher current rating is backward compatible. Applications designed for 1A operation will function correctly with the 3A-rated substitute. No circuit modification is necessary for current capacity.

Q: Are the voltage ratings identical between the two parts?

A: Yes. Both components are rated for 125V AC and 30V DC, ensuring electrical compatibility in voltage-dependent applications.

Q: Does the larger panel cutout diameter (16.00mm) affect mechanical compatibility?

A: Yes. The substitute requires a larger cutout. Existing panel designs with 12.30mm cutouts must be mechanically modified to accommodate the 16.00mm diameter.

Q: What termination options are available with the substitute?

A: The YB25SKW01-5D24-JD offers Solder and Quick Connect 0.110" (2.8mm) termination. The original part provides Solder Lug termination only. Selection depends on circuit board design requirements.

Q: How do the mechanical and electrical life ratings compare?

A: The substitute provides significantly higher cycle ratings: 1,000,000 mechanical cycles (versus 100,000) and 100,000 electrical cycles (versus 50,000). This results in extended operational life and improved reliability.

Q: Is RoHS3 compliance confirmed for the substitute?

A: RoHS3 compliance is confirmed for the original KB25SKW01-5D24-JD. Compliance status for the YB25SKW01-5D24-JD should be verified directly with NKK Switches.

Q: Can the illumination voltage difference (24VDC versus 2VDC) be accommodated in existing designs?

A: Circuit modification is required. The lower illumination voltage of the substitute may require changes to power supply design or illumination control circuitry.
