KB16SKW01-5C-JB Equivalent & Substitute Parts

Part Overview

The KB16SKW01-5C-JB is a pushbutton switch with SPDT (Single Pole Double Throw) circuit configuration, rated for 1A at 125V AC and 30V DC. This illuminated panel mount switch features a square button actuator with red LED illumination and solder lug termination. The product is currently obsolete, making identification of compatible substitute parts essential for system maintenance, repair, and redesign applications where continued functionality is required.

Substitute Part Grouping Explanation

The YB16SKW01-5C-JB qualifies as a substitute based on the following matching parameters:

Matching Criteria:

Identical circuit configuration (SPDT)
Identical switch function (On-On)
Identical voltage rating - AC (125V)
Identical voltage rating - DC (30V)
Identical mounting type (Panel Mount, Front)
Identical illumination type and color (LED, Red)
Identical illumination voltage (1.9 VDC)
Identical actuator type (Square, Button)
Identical operating temperature range (-25°C to 50°C)
Identical RoHS compliance status (ROHS3 Compliant)

Differing Parameters: The YB16SKW01-5C-JB has a higher current rating (3A versus 1A), larger panel cutout diameter (16.00mm versus 12.30mm), enhanced mechanical life (200,000 versus 100,000 cycles), and improved electrical life (100,000 versus 50,000 cycles). The substitute also features tactile feedback and offers dual termination options (Solder and Quick Connect).

Engineering Selection Recommendations

The YB16SKW01-5C-JB is an active product with current manufacturing support, whereas the KB16SKW01-5C-JB is obsolete. Both parts maintain ROHS3 compliance and identical electrical specifications for voltage and circuit function. The substitute part offers superior performance characteristics including higher current capacity, extended mechanical and electrical life cycles, and dual termination options.

Panel cutout diameter differences (12.30mm versus 16.00mm) require mechanical evaluation for panel compatibility. Applications with current requirements at or below 1A can safely use the YB16SKW01-5C-JB without derating. The substitute's enhanced durability metrics provide extended service life in equivalent operating conditions.

Frequently Asked Questions (FAQ)

Q: Can YB16SKW01-5C-JB directly replace KB16SKW01-5C-JB in existing designs?

A: Electrical compatibility is confirmed across all critical parameters: SPDT circuit, On-On function, 125V AC / 30V DC ratings, and identical illumination specifications. Panel cutout diameter must be verified for mechanical fit. The larger 16.00mm cutout of the substitute may require panel modification if the original 12.30mm opening cannot be enlarged.

Q: What are the implications of the higher 3A current rating on the substitute?

A: The YB16SKW01-5C-JB's 3A rating exceeds the original 1A specification. This provides design margin for applications operating at or below 1A. No derating or circuit modification is required for equivalent current loads.

Q: Are termination style differences significant for substitution?

A: The KB16SKW01-5C-JB uses solder lug termination exclusively. The YB16SKW01-5C-JB offers both solder and quick connect options. Existing wiring harnesses designed for solder lug connections remain compatible. Quick connect termination is an additional capability not required for direct substitution.

Q: How do the mechanical and electrical life differences affect component selection?

A: The YB16SKW01-5C-JB provides doubled mechanical life (200,000 versus 100,000 cycles) and doubled electrical life (100,000 versus 50,000 cycles). These enhanced specifications extend service intervals and improve reliability in high-cycle applications without introducing compatibility issues.

Q: What compliance certifications apply to both parts?

A: Both KB16SKW01-5C-JB and YB16SKW01-5C-JB maintain ROHS3 compliance and are classified under ECCN EAR99 with identical HTSUS coding (8536.50.9033).
