SMP6-UWDC LED Cool White Diffused 6-SMD Equivalent & Substitute Parts

Part Overview

The SMP6-UWDC is a cool white diffused LED indication component manufactured by Bivar Inc., designed for surface mount applications in 6-SMD, J-Lead packaging. This part operates at 3.3V forward voltage with a 4000 millicandela rating and 140° viewing angle, featuring a 4.00mm diameter round lens with flat top and yellow lens color.

The SMP6-UWDC is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for applications currently utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SMP6-UWDC is determined by strict equivalence across the following critical parameters:

Optical Characteristics: Color (White, Cool), wavelength dominant (8000K), lens transparency (Diffused), millicandela rating (4000mcd), and viewing angle (140°) must remain constant to preserve intended indication functionality.

Electrical Characteristics: Forward voltage (Vf) and test current (60mA) define the power supply requirements and circuit compatibility.

Mechanical Characteristics: Lens size (4.00mm diameter), lens style (Round with Flat Top), mounting type (Surface Mount), and package type (6-SMD, J-Lead / 6-PLCC) ensure physical and electrical interface compatibility.

Environmental Compliance: Moisture sensitivity level (MSL 4) and regulatory classifications (ECCN, HTSUS) must be maintained for manufacturing and supply chain requirements.

The SMTL6-UWDC meets these substitution criteria with allowable variations in forward voltage (3V versus 3.3V) and physical dimensions within acceptable tolerances for surface mount assembly.

Parameter Comparison

Engineering Selection Recommendations

The SMTL6-UWDC is the direct substitute for the obsolete SMP6-UWDC. Both components are manufactured by Bivar Inc. and share identical optical, electrical, and mechanical specifications with the following considerations:

Product Status: The SMTL6-UWDC maintains active product status, ensuring ongoing availability and manufacturer support, whereas the SMP6-UWDC is obsolete and subject to supply discontinuation.

Regulatory Compliance: Both parts carry identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications, maintaining compliance with export and tariff requirements.

RoHS and REACH Status: The SMTL6-UWDC is ROHS3 Compliant and REACH Unaffected, providing enhanced environmental and regulatory alignment for new designs and manufacturing processes.

Forward Voltage Variation: The SMTL6-UWDC operates at 3V typical forward voltage compared to 3.3V for the SMP6-UWDC. This 0.3V reduction is within acceptable operating margins for standard 3.3V supply circuits and does not compromise functional performance.

Physical Dimensions: The SMTL6-UWDC exhibits a maximum length of 5.40mm (versus 5.00mm) and maximum height of 1.60mm (versus 1.50mm). These dimensional variations remain within standard surface mount assembly tolerances and do not affect PCB layout compatibility for typical applications.

Packaging: The SMTL6-UWDC is supplied in Tape & Reel (TR) format, supporting automated assembly processes and reducing component handling costs compared to alternative packaging configurations.

Frequently Asked Questions (FAQ)

Q: Can the SMTL6-UWDC directly replace the SMP6-UWDC in existing designs?

A: Yes. The SMTL6-UWDC is a direct substitute meeting all critical optical, electrical, and mechanical parameters. The 0.3V forward voltage reduction and minor dimensional variations do not affect functional compatibility in standard applications.

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

A: The SMP6-UWDC operates at 3.3V typical forward voltage, while the SMTL6-UWDC operates at 3V. This 0.3V reduction is within normal LED operating tolerances and does not require circuit redesign for applications using standard 3.3V or 5V supply rails.

Q: Are there any PCB layout considerations due to dimensional differences?

A: The SMTL6-UWDC is 0.40mm longer (5.40mm versus 5.00mm) and 0.10mm taller (1.60mm versus 1.50mm) than the SMP6-UWDC. These variations are within standard surface mount component tolerances and do not require PCB footprint modification for typical applications with standard design margins.

Q: What packaging format is the SMTL6-UWDC supplied in?

A: The SMTL6-UWDC is supplied in Tape & Reel (TR) format, optimized for automated pick-and-place assembly processes.

Q: Are both parts compliant with current environmental regulations?

A: The SMTL6-UWDC is ROHS3 Compliant and REACH Unaffected. Both parts carry identical ECCN and HTSUS classifications, maintaining regulatory compliance for manufacturing and export.

Q: Why is the SMP6-UWDC classified as obsolete?

A: The SMP6-UWDC is no longer in active production. The SMTL6-UWDC represents the current active equivalent, ensuring continued supply chain availability and manufacturer support.

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

A: Both the SMP6-UWDC and SMTL6-UWDC carry MSL 4 (72 Hours) classification, requiring controlled storage and handling conditions to prevent moisture absorption during manufacturing processes.
