Key Parameters

Substitute Part Grouping Explanation

Substitution of the UB225SKW03CF-1JB is determined by strict equivalence across the following critical parameters:

• Circuit Configuration: DPDT topology must be maintained
• Current and Voltage Ratings: 5A (AC/DC), 125V AC, 30V DC specifications must be met or exceeded
• Mounting and Termination: Through-hole mounting with PC pin termination required
• Actuator and Illumination: Square button actuator with LED illumination (green/red) at 2.1, 4.6 VDC
• Environmental Specifications: Operating temperature range -25°C to 50°C, sealed construction
• Mechanical and Electrical Life: 1,000,000 mechanical cycles and 10,000 electrical cycles minimum

The substitute part UB225SKW036CF-1JB meets all these criteria while maintaining identical electrical and mechanical specifications within the NKK Switches UB2 series.

Frequently Asked Questions (FAQ)

Q: Can UB225SKW036CF-1JB be used as a direct replacement for UB225SKW03CF-1JB?

A: Yes. Both components are electrically and mechanically identical across all specified parameters. The substitute part is pin-compatible and functionally equivalent for all applications requiring DPDT pushbutton switch operation at 5A/125V AC with LED illumination.

Q: What is the difference between these two part numbers?

A: The primary difference is product status. UB225SKW03CF-1JB is obsolete, while UB225SKW036CF-1JB is active production. The substitute part also includes ROHS3 compliance certification. All electrical, mechanical, and environmental specifications remain identical.

Q: Are there packaging differences between these parts?

A: The main part number does not specify packaging format, while UB225SKW036CF-1JB is supplied in tray packaging. This represents a packaging variation only and does not affect electrical or mechanical compatibility.

Q: What parameters must remain constant for substitution?

A: Circuit configuration (DPDT), current rating (5A AC/DC), voltage ratings (125V AC / 30V DC), mounting type (through-hole), actuator style (square button), illumination type (LED green/red), and termination style (PC pin) must all be maintained for functional equivalence.

Q: Is the illumination voltage specification critical for substitution?

A: Yes. Both parts require illumination voltage of 2.1 or 4.6 VDC. Circuit designs must supply one of these specified voltages to the LED illumination circuit for proper operation.
