Parameter Comparison

Engineering Selection Recommendations

The 5219946F from Dialight is a qualified substitute for the obsolete 5BWC2.515. Selection is based on the following factors:

Product Status: The 5219946F maintains active product status with confirmed inventory availability (3147 pcs), whereas the 5BWC2.515 is obsolete with limited stock (1125 pcs).

Compliance & Certifications: The 5219946F is RoHS3 compliant and REACH unaffected, providing superior regulatory alignment for current manufacturing standards. Both components share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications.

Mechanical Compatibility: Both components utilize identical 5mm through-hole radial mounting with round domed clear lenses, ensuring direct PCB footprint compatibility without layout modifications.

Electrical Parameters: Forward voltage variance of 0.1V (3.7V vs 3.8V) falls within standard circuit design tolerances. Test current remains constant at 20mA. Peak wavelength separation (468nm vs 470nm) maintains blue spectrum consistency.

Performance Variance: The 5219946F exhibits lower brightness (1010mcd vs 2500mcd) and wider viewing angle (30° vs 15°). These characteristics require circuit-level evaluation to confirm suitability for specific application requirements.

Frequently Asked Questions (FAQ)

Q: Can the 5219946F directly replace the 5BWC2.515 without PCB modifications?

A: Yes. Both components share identical 5mm T-1 3/4 through-hole radial package geometry, enabling direct footprint compatibility without PCB layout changes.

Q: What is the impact of the 0.1V forward voltage difference?

A: The 3.7V to 3.8V variance is within standard circuit design tolerance. Series resistor values may require minor adjustment to maintain identical test current (20mA), but this is a routine design parameter optimization.

Q: Why does the 5219946F have lower brightness (1010mcd vs 2500mcd)?

A: Brightness rating difference reflects distinct LED die specifications between manufacturers. Application suitability depends on visibility requirements in the target circuit. Verify that 1010mcd meets minimum illumination specifications for your indication function.

Q: Is the wider viewing angle (30° vs 15°) a concern?

A: The 30° viewing angle of the 5219946F provides broader visibility compared to the 15° specification of the 5BWC2.515. This is generally advantageous for indication applications but should be verified against specific directional visibility requirements.

Q: What compliance advantages does the 5219946F offer?

A: The 5219946F is RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards. The 5BWC2.515 lacks documented compliance certifications, making the substitute preferable for new designs and ongoing production.

Q: Are there inventory considerations for this substitution?

A: The 5219946F has significantly higher availability (3147 pcs) compared to the obsolete 5BWC2.515 (1125 pcs), ensuring supply chain continuity for production requirements.
