Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB15SKW01-5F-JF is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Circuit configuration (SPDT)
• Switch function (On-Mom momentary operation)
• Voltage ratings (125V AC minimum, 30V DC minimum)
• Mounting type (Panel Mount, Front)
• Actuator type (Square, Button)
• Illumination type (LED, Green)
• Operating temperature range (-25°C to 50°C minimum)
• Panel cutout dimensions (12.30mm circular)
• Termination compatibility (solder-based connection)

Allowable Variation Parameters:

• Current rating (equal to or greater than 1A)
• Illumination voltage (nominal 2.1 VDC ±0.2V acceptable)
• Mechanical and electrical life cycles (equal to or greater than specified)
• Packaging format (does not affect functional compatibility)

The YB15SKW01-5F-JF qualifies as a substitute based on matching all mandatory parameters while exceeding performance specifications in current rating (3A vs. 1A), mechanical life (1,000,000 vs. 100,000 cycles), and electrical life (100,000 vs. 50,000 cycles).

Parameter Comparison

Engineering Selection Recommendations

The YB15SKW01-5F-JF is a direct functional substitute for the obsolete KB15SKW01-5F-JF. Both components maintain ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. The substitute part is currently in active production status with confirmed inventory availability (1146 pieces), whereas the original part is obsolete with limited stock (778 pieces).

The YB15SKW01-5F-JF provides enhanced performance specifications across current capacity, mechanical durability, and electrical cycle life, making it suitable for applications requiring extended operational reliability. The panel cutout diameter increases from 12.30mm to 16.00mm, requiring mechanical panel modification for direct installation. Termination style changes from solder lug to solder with quick connect 0.110" (2.8mm) option, necessitating circuit board connection redesign.

Frequently Asked Questions (FAQ)

Q: Can the YB15SKW01-5F-JF be used as a direct drop-in replacement for KB15SKW01-5F-JF?

A: Functional compatibility is confirmed for circuit operation. However, mechanical and electrical interface modifications are required. The panel cutout diameter differs (16.00mm vs. 12.30mm), and termination style changes from solder lug to solder with quick connect options. These differences require panel drilling adjustment and PCB connection redesign.

Q: What are the key differences in electrical performance?

A: The substitute part YB15SKW01-5F-JF exceeds the original specifications in current rating (3A vs. 1A), mechanical life (1,000,000 vs. 100,000 cycles), and electrical life (100,000 vs. 50,000 cycles). Illumination voltage increases marginally from 2.1 VDC to 2.2 VDC, remaining within acceptable tolerance for LED green illumination circuits.

Q: Are there compliance or certification concerns with substitution?

A: Both parts maintain ROHS3 compliance and REACH unaffected status. No compliance barriers exist for substitution in applications subject to these regulatory frameworks.

Q: What packaging considerations apply to the substitute part?

A: The YB15SKW01-5F-JF is supplied in bulk packaging, whereas the original KB15SKW01-5F-JF packaging format is not specified. Bulk packaging does not affect functional performance or component compatibility.

Q: Is the illumination voltage difference significant?

A: The illumination voltage difference (2.1 VDC to 2.2 VDC) represents a 0.1 VDC increase. This variation is within standard LED green illumination circuit tolerances and does not require circuit redesign for typical applications operating within the -25°C to 50°C temperature range.
