YB03WKW01-6B-JB LED Panel Indicator Equivalent & Substitute Parts

Part Overview

The YB03WKW01-6B-JB is an LED panel indicator manufactured by NKK Switches, classified as an active product with full RoHS3 compliance. This white diffused LED indicator is designed for panel-mount applications requiring quick-connect termination. Substitute parts become necessary when the primary part experiences supply constraints, extended lead times, or inventory depletion, while maintaining identical electrical and mechanical specifications for direct replacement in existing designs.

Substitute Part Grouping Explanation

Substitution eligibility for the YB03WKW01-6B-JB is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part YB03KW01-6B-JB qualifies as a direct equivalent based on the following matching criteria:

Electrical specifications: Identical voltage rating (3.6V) and current rating (30mA)

Optical characteristics: Matching lamp color (White), lens color (White), and lens transparency (Diffused)

Mechanical compatibility: Identical panel cutout shape (Round), cutout dimensions (0.63"/16.00mm), lens size (21.00mm x 15.00mm), and lens style (Rectangle with Flat Top)

Termination interface: Matching quick-connect termination style (0.110"/2.8mm)

Regulatory compliance: Both parts maintain ROHS3 compliance, REACH unaffected status, and MSL 1 rating

Series alignment: Both parts belong to the NKK Switches YB series

Parameter Comparison

Engineering Selection Recommendations

Both YB03WKW01-6B-JB and YB03KW01-6B-JB are active products with full regulatory compliance. Selection between these parts should be based on inventory availability and lead time requirements. The YB03KW01-6B-JB currently maintains higher inventory levels (946 pcs) compared to YB03WKW01-6B-JB (615 pcs), making it suitable for applications where supply continuity is a priority. Both parts carry identical RoHS3 compliance and REACH unaffected status, ensuring regulatory requirements are met regardless of which part is selected. The MSL 1 rating on both parts indicates unlimited shelf life under standard storage conditions.

Frequently Asked Questions (FAQ)

Q: Can YB03KW01-6B-JB be used as a direct replacement for YB03WKW01-6B-JB?

A: Yes. Both parts are parametrically equivalent across all electrical, optical, and mechanical specifications. They share identical voltage (3.6V), current (30mA), panel cutout dimensions (0.63"/16.00mm), lens size (21.00mm x 15.00mm), and quick-connect termination (0.110"/2.8mm). No circuit modifications or mechanical adjustments are required.

Q: Are there any compliance differences between these parts?

A: No. Both parts maintain identical RoHS3 compliance, REACH unaffected status, and MSL 1 rating. They are suitable for applications with identical regulatory requirements.

Q: What is the difference between the part numbers YB03WKW01-6B-JB and YB03KW01-6B-JB?

A: The part numbers differ in their base designations (YB03WKW01 versus YB03KW01), but all specified electrical, optical, and mechanical parameters are identical. The difference reflects internal NKK Switches product line organization and does not affect functional performance or compatibility.

Q: Which part should be selected for new designs?

A: Either part is suitable for new designs. Selection should be based on current inventory availability and supplier lead times. Both parts are active products with full regulatory compliance.

Q: Are there any packaging differences?

A: Both parts are supplied in Box packaging. No packaging-related compatibility issues exist between these parts.
