Key Parameters

Substitute Part Grouping Explanation

The WP934CB/YD from Kingbright qualifies as a substitute for the HLMP1420101F based on the following alignment of critical parameters:

Matching Parameters:

• Color: Yellow
• Configuration: Single
• Current Rating: 20mA
• Lens Style: Round with Domed Top
• Mounting Type: Through Hole, Right Angle
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected
• ECCN: EAR99
• HTSUS Code: 8541.41.0000

Allowable Variations:

• Wavelength Peak: 583nm (HLMP1420101F) vs. 590nm (WP934CB/YD) — both within yellow spectrum range
• Voltage Rating: 2V (HLMP1420101F) vs. 2.1V (WP934CB/YD) — compatible operating range
• Millicandela Rating: 7mcd (HLMP1420101F) vs. 11.5mcd (WP934CB/YD) — substitute provides higher brightness
• Viewing Angle: 60° (HLMP1420101F) vs. 40° (WP934CB/YD) — substitute has narrower viewing angle
• Lens Type: Standard (HLMP1420101F) vs. Diffused, Tinted (WP934CB/YD) — optical characteristic difference
• Lens Size: 3.00mm Dia (HLMP1420101F) vs. 3mm, T-1 (WP934CB/YD) — equivalent mechanical footprint

Parameter Comparison

Engineering Selection Recommendations

The WP934CB/YD is an active production substitute for the obsolete HLMP1420101F. Both components share identical mounting type, current rating, and regulatory compliance status. The substitute maintains compatibility with existing through-hole, right-angle PCB layouts.

The WP934CB/YD operates at 2.1V compared to the original 2V specification, representing a 5% increase within acceptable tolerance for indicator LED applications. The substitute delivers 11.5mcd brightness versus the original 7mcd, providing enhanced visibility. The narrower 40° viewing angle of the substitute compared to the original 60° angle represents a trade-off in directional visibility characteristics.

The diffused, tinted lens type of the WP934CB/YD differs from the standard lens of the HLMP1420101F, affecting light distribution and color saturation. Both components maintain identical moisture sensitivity classification and regulatory certifications, ensuring equivalent environmental performance.

Frequently Asked Questions (FAQ)

Q: Can the WP934CB/YD directly replace the HLMP1420101F in existing designs?

A: The WP934CB/YD is mechanically and electrically compatible for through-hole, right-angle mounting applications. The 0.1V voltage increase and differing lens characteristics require circuit validation to confirm acceptable performance in the specific application context.

Q: What is the significance of the wavelength difference between 583nm and 590nm?

A: Both wavelengths fall within the yellow spectrum range. The 7nm difference represents a shift toward longer wavelengths but maintains visual color consistency for indicator applications.

Q: How does the viewing angle difference affect circuit board indicator functionality?

A: The HLMP1420101F provides a 60° viewing angle, while the WP934CB/YD provides 40°. The narrower angle of the substitute concentrates light output in a more focused direction, potentially affecting visibility from wider observation angles.

Q: What does the diffused, tinted lens type mean for the WP934CB/YD?

A: The diffused, tinted lens scatters light more broadly than a standard lens and includes color tinting. This affects light distribution pattern and perceived color intensity compared to the original component.

Q: Are both components compliant with current environmental regulations?

A: Both the HLMP1420101F and WP934CB/YD maintain REACH Unaffected status and identical moisture sensitivity classification. The WP934CB/YD carries ROHS3 Compliant certification, confirming compliance with current restriction of hazardous substances requirements.

Q: What inventory considerations apply to these components?

A: The HLMP1420101F is obsolete with limited remaining stock (748 pcs). The WP934CB/YD is in active production with significantly higher availability (5054 pcs), supporting long-term supply chain continuity.
