Key Parameters

Substitute Part Grouping Explanation

Substitution of the KB16RKW01-01-JC is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Circuit configuration (SPDT maintained)
• Voltage rating compatibility (125V AC minimum)
• Mounting type (Panel Mount, Front)
• Panel cutout dimensions (mechanical fit requirement)
• Operating temperature range (-25°C to 50°C)
• RoHS3 compliance status

Allowable Variation Parameters:

• Current rating (substitute may exceed 1A requirement)
• Illumination technology (neon to LED transition acceptable)
• Illumination voltage (different supply voltage acceptable if system supports)
• Mechanical and electrical life cycles (higher values acceptable)
• Termination style (solder lug to solder/quick connect acceptable)

The YB16RKW01-5C24-JC qualifies as a substitute based on maintained SPDT circuit, compatible voltage ratings, identical mounting configuration, and RoHS3 compliance. Differences in current rating (3A vs 1A), illumination technology (LED vs neon), and panel cutout diameter (16.00mm vs 12.30mm) represent functional improvements and design evolution rather than incompatibilities.

Parameter Comparison

Engineering Selection Recommendations

The YB16RKW01-5C24-JC is the designated substitute for KB16RKW01-01-JC applications. Selection is supported by the following engineering factors:

Compliance and Availability:

• YB16RKW01-5C24-JC maintains active product status, ensuring long-term availability and supply chain continuity
• Both components achieve ROHS3 compliance, satisfying regulatory requirements
• Both components are REACH unaffected and classified as EAR99 for export control purposes

Functional Equivalence:

• SPDT circuit configuration is preserved, maintaining switching logic compatibility
• Voltage ratings (125V AC / 30V DC) are identical, ensuring direct electrical compatibility
• Panel mount front installation type is maintained
• Operating temperature range (-25°C to 50°C) is identical

Design Improvements in Substitute:

• Current rating increase from 1A to 3A provides enhanced capacity margin
• LED illumination replaces neon technology, offering improved reliability and extended service life
• Mechanical life doubled from 100,000 to 200,000 cycles
• Electrical life doubled from 50,000 to 100,000 cycles

Installation Consideration:

• Panel cutout diameter increases from 12.30mm to 16.00mm, requiring mechanical panel modification
• Illumination voltage changes from 110 VAC to 24 VDC, requiring power supply adjustment

Frequently Asked Questions (FAQ)

Q: Can YB16RKW01-5C24-JC directly replace KB16RKW01-01-JC without modifications?

A: Electrical and functional replacement is direct. Mechanical panel modification is required due to increased cutout diameter (16.00mm vs 12.30mm). Illumination power supply must be changed from 110 VAC to 24 VDC.

Q: What is the primary reason for substitution?

A: KB16RKW01-01-JC is classified as obsolete. YB16RKW01-5C24-JC is an active product from the same manufacturer with equivalent SPDT circuit configuration and voltage ratings.

Q: Are the voltage ratings compatible?

A: Yes. Both components are rated for 125V AC and 30V DC operation, ensuring direct electrical compatibility in existing circuits.

Q: What are the differences in illumination?

A: KB16RKW01-01-JC uses neon red illumination at 110 VAC. YB16RKW01-5C24-JC uses LED red illumination at 24 VDC. LED technology provides longer operational life and improved reliability.

Q: Is the current rating difference significant?

A: The substitute provides 3A capacity versus the original 1A rating. This represents a functional improvement and does not create incompatibility. Applications requiring 1A operation remain fully supported.

Q: What mechanical considerations apply to panel installation?

A: The substitute requires a larger panel cutout (16.00mm diameter vs 12.30mm). Existing panel openings must be enlarged or new panels fabricated to accommodate the larger diameter.

Q: Are both components RoHS compliant?

A: Yes. Both KB16RKW01-01-JC and YB16RKW01-5C24-JC are ROHS3 compliant, meeting environmental and regulatory standards.

Q: What is the impact of doubled mechanical and electrical life cycles?

A: The substitute offers extended service life with 200,000 mechanical cycles and 100,000 electrical cycles compared to 100,000 and 50,000 respectively. This represents improved durability and reduced maintenance frequency.
