• Millicandela Rating: Brightness sufficient for indication applications
• Viewing Angle: Acceptable for intended viewing geometry
• Wavelength: Blue spectrum (468-472nm range)
• Physical Height: Compatible with PCB assembly constraints

The substitute part 5219946F from Dialight meets all primary matching criteria and operates within compatible electrical parameters for direct substitution in through-hole LED indication circuits.

Parameter Comparison

Engineering Selection Recommendations

Substitution Feasibility:

The 5219946F from Dialight is a direct functional substitute for the obsolete 5BWC2.515F. Both components share identical mechanical form factors, mounting configurations, and primary electrical characteristics for through-hole LED indication applications.

Key Considerations:

1. Brightness Differential: The 5219946F operates at 1010mcd compared to the original 2500mcd. Circuit designs relying on the higher brightness specification of the 5BWC2.515F require evaluation to confirm the substitute brightness is adequate for the intended application.

2. Viewing Angle: The substitute provides a 30° viewing angle versus the original 15°. This wider angle may be advantageous for applications requiring broader visibility but should be confirmed against optical design requirements.

3. Forward Voltage: The 0.1V difference (3.8V vs 3.7V) is within acceptable tolerance for series-connected LED circuits and does not require circuit redesign.

4. Compliance Status: The 5219946F carries active product status and ROHS3 compliance certification, ensuring long-term availability and regulatory alignment with current environmental standards.

5. Physical Dimensions: The 0.10mm height difference is negligible for standard PCB assembly processes and does not impact mechanical fit.

Frequently Asked Questions (FAQ)

Q: Can the 5219946F directly replace the 5BWC2.515F without circuit modification?

A: Yes, for most through-hole LED indication applications. The 0.1V forward voltage difference does not require circuit redesign in series-connected configurations. However, applications with strict brightness requirements should evaluate whether 1010mcd is sufficient, as this is lower than the original 2500mcd specification.

Q: What is the impact of the different viewing angles (15° vs 30°)?

A: The substitute's wider 30° viewing angle provides broader visibility. If the original design required the narrower 15° viewing angle for specific optical isolation or directional indication purposes, this difference should be evaluated against application requirements.

Q: Are the physical dimensions compatible with existing PCB layouts?

A: Yes. Both components use identical 5mm through-hole radial packages with negligible height difference (0.10mm). No PCB redesign is necessary.

Q: Why is the 5219946F brightness lower than the original?

A: The 5219946F is specified at 1010mcd while the 5BWC2.515F is rated at 2500mcd. This reflects different LED die specifications between manufacturers. Applications requiring the higher brightness level should confirm the substitute meets visibility requirements or consider alternative high-brightness blue LED options.

Q: Is the 5219946F compliant with current environmental regulations?

A: Yes. The 5219946F carries ROHS3 compliance certification and REACH unaffected status, meeting current environmental standards. The original 5BWC2.515F compliance status was not specified.

Q: What is the wavelength difference between these components?

A: Both components emit in the blue spectrum. The 5BWC2.515F has a peak wavelength of 468nm while the 5219946F is specified at 470nm. This 2nm difference is imperceptible to human vision and does not affect functional performance in indication applications.

Q: Are there any supply chain advantages to using the 5219946F?

A: Yes. The 5219946F is an active product with 3147 units in stock, compared to the obsolete 5BWC2.515F with limited remaining inventory of 880 units. The substitute ensures long-term procurement availability.
