Key Parameters

Substitute Part Grouping Explanation

Substitution of the KB26SKW01-01-JC is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Circuit configuration must remain DPDT
• Voltage rating must support minimum 125V AC operation
• Current rating must equal or exceed 1A (AC/DC)
• DC voltage rating must support minimum 30V

Mechanical Compatibility Requirements:

• Mounting type must be Panel Mount, Front
• Switch function must be On-On
• Actuator type must be Square, Button
• Operating temperature range must encompass -25°C to 50°C

Illumination Compatibility:

• Illumination color must be Red
• Illumination type may differ (Neon or LED acceptable)

Regulatory & Environmental Requirements:

• RoHS3 compliance required
• MSL rating of 1 (Unlimited) acceptable

The YB26SKW01-5C-JC meets all electrical, mechanical, and regulatory requirements for substitution. The higher current rating (3A vs. 1A) and enhanced mechanical/electrical life cycles provide improved performance margins. The LED illumination with voltage reduction lighting represents a modern alternative to neon illumination while maintaining functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

The YB26SKW01-5C-JC is the qualified substitute for KB26SKW01-01-JC applications. Selection is based on the following engineering criteria:

Product Status: The main part is obsolete, while the substitute is active, ensuring long-term availability and supply chain continuity.

Electrical Performance: The substitute exceeds minimum electrical requirements with a 3A current rating versus the original 1A specification, while maintaining identical voltage ratings (125V AC, 30V DC). This provides operational margin for applications with variable load conditions.

Mechanical Durability: The substitute offers doubled mechanical life (200,000 cycles vs. 100,000 cycles) and doubled electrical life (100,000 cycles vs. 50,000 cycles), extending component service life.

Regulatory Compliance: Both components maintain ROHS3 compliance and MSL 1 rating, meeting environmental and moisture sensitivity requirements.

Illumination Technology: The LED red illumination with voltage reduction lighting in the substitute represents a modern alternative to neon illumination, offering improved reliability and reduced power consumption while maintaining visual equivalence.

Panel Integration: Both components share identical mounting type (Panel Mount, Front), actuator configuration (Square, Button), and operating temperature range (-25°C to 50°C), ensuring direct mechanical and thermal compatibility.

Termination Consideration: The substitute features Solder and Quick Connect termination options (0.110" / 2.8mm), compared to the original Solder Lug termination. Installation procedures must account for this termination style difference.

Frequently Asked Questions (FAQ)

Q: Can YB26SKW01-5C-JC directly replace KB26SKW01-01-JC in existing designs?

A: Yes, for electrical and mechanical functionality. Both components share DPDT circuitry, identical voltage ratings (125V AC, 30V DC), matching mounting type (Panel Mount, Front), and identical operating temperature range (-25°C to 50°C). The higher current rating (3A vs. 1A) is backward compatible. Termination style differs; installation procedures must be adjusted accordingly.

Q: What is the impact of the higher current rating in the substitute?

A: The YB26SKW01-5C-JC 3A rating exceeds the original 1A specification, providing operational margin. This does not create compatibility issues; the substitute can safely handle applications rated at or below 1A. Higher current capacity improves reliability under variable load conditions.

Q: How does LED illumination differ from neon illumination?

A: Both provide red illumination for panel indication. The substitute uses LED with voltage reduction lighting (1.9 VDC) versus neon (110 VAC). LED illumination offers improved reliability, longer service life, and reduced power consumption. Visual indication remains functionally equivalent.

Q: Are there panel cutout dimension differences?

A: Yes. The main part requires a 12.30mm circular cutout; the substitute requires 16.00mm. Panel modifications are necessary for physical installation of the substitute.

Q: What termination changes are required?

A: The main part uses Solder Lug termination; the substitute offers Solder and Quick Connect (0.110" / 2.8mm) options. Wiring and connection procedures must be adapted to the substitute's termination style.

Q: Do both components meet current regulatory requirements?

A: Yes. Both are ROHS3 compliant and carry MSL 1 (Unlimited) ratings, meeting environmental and moisture sensitivity standards.
