Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LE-0903-04W is determined by strict adherence to the following parameters:

Fixed Parameters (Must Match):

• Base Type: Wedge
• Color: White, Cool
• Wavelength: 6800K
• Size / Dimension: 0.409" Dia x 0.799" H (10.40mm x 20.30mm)
• Configuration: Single
• Manufacturer: JKL Components Corp.
• Base Product Number: LE-0903

Variable Parameter (Allows Substitution):

• Voltage - Forward (Vf) (Typ): 24V (main part) vs. 12V (substitute part)

The LE-0903-02W qualifies as a parametric equivalent because it maintains identical physical dimensions, optical characteristics, base type, and compliance certifications while operating at a different forward voltage rating of 12V. This voltage variation represents the primary distinction between the main part and its substitute.

Parameter Comparison

Engineering Selection Recommendations

Both LE-0903-04W and LE-0903-02W maintain Active product status with identical regulatory compliance profiles. Both parts are ROHS3 compliant and REACH unaffected, ensuring equivalent environmental and regulatory standing. The primary selection criterion is voltage requirement compatibility with the target application circuit. The LE-0903-04W operates at 24V forward voltage, while the LE-0903-02W operates at 12V forward voltage. Selection must be based on the system voltage specification. Both parts share identical physical dimensions, optical output characteristics, and moisture sensitivity ratings, ensuring mechanical and thermal interchangeability within their respective voltage domains.

Frequently Asked Questions (FAQ)

Q: Can LE-0903-02W replace LE-0903-04W in any application?

A: Substitution is valid only when the target application operates at 12V. The forward voltage rating must match the circuit design. Using a 12V lamp in a 24V circuit or vice versa will result in improper operation or component failure.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both LE-0903-04W and LE-0903-02W share identical dimensions of 0.409" diameter by 0.799" height (10.40mm x 20.30mm) and use the same wedge base type, ensuring mechanical compatibility in the same socket.

Q: Do both parts have the same color temperature and optical output?

A: Yes. Both parts operate at 6800K wavelength with white, cool color characteristics and single LED configuration, providing identical optical performance.

Q: What is the difference between these two parts?

A: The sole difference is the forward voltage rating: LE-0903-04W operates at 24V, while LE-0903-02W operates at 12V. All other electrical, optical, and mechanical parameters are identical.

Q: Are both parts compliant with environmental regulations?

A: Yes. Both LE-0903-04W and LE-0903-02W are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the moisture sensitivity level for these lamps?

A: Both parts have a Moisture Sensitivity Level (MSL) of 1, indicating unlimited shelf life without special moisture control requirements.
