Substitute Part Grouping Explanation

The UB226SKW036CF-3JB qualifies as a direct substitute for the UB226SKW03CF-3JB based on identical electrical and mechanical parameters. Both components share the same NKK Switches UB2 series designation and maintain equivalent performance specifications across all critical functional parameters: DPDT circuit configuration, 5A current rating at 125V AC / 30V DC, square button actuator with dual LED illumination (Green/Red), PC pin termination, and identical operating temperature range and mechanical life rating.

The substitution is valid based on the following matching parameters:

• Circuit configuration (DPDT)
• Current and voltage ratings (5A, 125V AC, 30V DC)
• Mounting type (Through Hole)
• Actuator type and illumination characteristics
• Termination style (PC Pin)
• Environmental specifications (Operating temperature, sealing)
• Mechanical and electrical life ratings

Parameter Comparison

Engineering Selection Recommendations

The UB226SKW036CF-3JB is the appropriate substitute for the obsolete UB226SKW03CF-3JB. The substitute part maintains active product status with NKK Switches, ensuring continued availability and supply chain reliability. A significant advantage of the substitute is its ROHS3 compliance, whereas the original part is RoHS non-compliant. This compliance improvement is relevant for applications subject to RoHS regulations. Both parts share identical electrical performance specifications and mechanical characteristics, supporting direct functional replacement in existing circuit designs.

Frequently Asked Questions (FAQ)

Q: Can UB226SKW036CF-3JB replace UB226SKW03CF-3JB in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent across all specified parameters, including circuit configuration, current/voltage ratings, actuator type, illumination characteristics, and environmental specifications.

Q: What is the primary difference between these parts?

A: The UB226SKW036CF-3JB is an active product with ROHS3 compliance, while the UB226SKW03CF-3JB is obsolete and RoHS non-compliant. Packaging differs (Tray for the substitute versus unspecified for the original).

Q: Are the illumination specifications identical?

A: Yes. Both parts feature LED illumination with Green/Red color options and identical nominal illumination voltage ratings of 2.1 and 4.6 VDC.

Q: Does the packaging difference affect electrical performance?

A: No. Packaging (Tray versus standard) does not affect component performance or functionality. It relates only to delivery and handling.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both components operate across the identical temperature range of -25°C to 50°C with equivalent mechanical and electrical life ratings.
