Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: SMTL6-BWC

The SMTL6-BWC is the direct equivalent substitute for the obsolete SMP6-BWC. Selection is based on the following engineering criteria:

Electrical Equivalence: The forward voltage differential of 0.4V (3.0V vs. 3.4V) is within standard tolerance for LED indication circuits and does not compromise functional performance. Both components operate at identical test current (60mA) and deliver identical brightness (1500mcd) and viewing angle (140°).

Mechanical Compatibility: Physical dimensions are compatible with existing PCB footprints. The length difference of 0.4mm and height difference of 0.10mm fall within standard PCB design tolerances for 6-SMD J-Lead packages. The identical lens size (4.00mm Dia) and style ensure optical performance equivalence.

Product Status and Compliance: The SMTL6-BWC carries active product status with improved inventory availability. The component is RoHS3 Compliant and REACH Unaffected, meeting current regulatory requirements. Moisture sensitivity level (MSL 4) is identical, requiring no changes to storage or handling procedures.

Packaging Consideration: The SMTL6-BWC is supplied in Tape & Reel format, which is standard for automated surface mount assembly. This packaging format is compatible with modern pick-and-place equipment and offers superior handling efficiency compared to bulk packaging.

Frequently Asked Questions (FAQ)

Q: Can the SMTL6-BWC directly replace the SMP6-BWC without circuit modification?

A: Yes. The SMTL6-BWC is electrically and mechanically equivalent. The 0.4V forward voltage difference (3.0V vs. 3.4V) is within standard LED circuit tolerance and does not require design changes. Both components operate at 60mA test current and deliver identical brightness and viewing angle specifications.

Q: What is the significance of the forward voltage difference between these parts?

A: The forward voltage difference of 0.4V is typical variation within LED component families and does not affect circuit functionality for indication applications. Standard LED driver circuits accommodate this range without modification. If your circuit operates at the absolute minimum voltage threshold, verify that 3.0V forward voltage remains acceptable for your specific application.

Q: Are the physical dimension differences significant?

A: The dimension differences are minimal and compatible with standard PCB design tolerances. The length difference of 0.4mm (5.00mm vs. 5.40mm) and height difference of 0.10mm (1.50mm vs. 1.60mm) do not affect PCB footprint compatibility for 6-SMD J-Lead packages. Existing PCB layouts require no modification.

Q: What is the difference between bulk and Tape & Reel packaging?

A: The SMP6-BWC is supplied in bulk packaging, while the SMTL6-BWC is supplied in Tape & Reel (TR) format. Tape & Reel is the standard packaging for automated surface mount assembly and offers superior handling efficiency, reduced component damage, and improved traceability. No functional difference exists between components in different packaging formats.

Q: Are there any compliance or regulatory differences?

A: The SMTL6-BWC is RoHS3 Compliant and REACH Unaffected, meeting current regulatory requirements. The SMP6-BWC, as an obsolete component, may not carry current compliance certifications. The SMTL6-BWC is the recommended choice for new designs and ongoing production requiring current regulatory compliance.

Q: What is the moisture sensitivity level, and does it affect handling?

A: Both components carry MSL 4 (72 Hours) rating, indicating identical moisture sensitivity. This classification requires storage in controlled humidity environments and limits the time components can be exposed to ambient conditions after packaging is opened. No changes to existing handling procedures are necessary when substituting the SMTL6-BWC.

Q: Is the SMTL6-BWC suitable for high-volume production?

A: Yes. The SMTL6-BWC is classified as an active product with significantly higher inventory availability (1752 Pcs vs. 762 Pcs). Tape & Reel packaging is optimized for automated assembly processes, making this component suitable for high-volume production environments.
