TLWR8902 Equivalent & Substitute Parts

Part Overview

The TLWR8902 is a red LED indication component from Vishay Semiconductor Opto Division's TELUX™ series, designed for through-hole mounting applications. This discrete 615nm red LED operates at 2.2V forward voltage with a 700mcd luminous intensity rating and features a clear, domed round lens in a 4-DIP package. The component is currently in active production status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when they maintain identical electrical characteristics, optical specifications, and mechanical compatibility within the same package form factor.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLWR8902 is determined by strict equivalence across the following critical parameters:

• Wavelength specification (dominant 615nm and peak 624nm)
• Electrical characteristics (forward voltage 2.2V, test current 70mA)
• Optical performance (700mcd luminous intensity, 90° viewing angle)
• Mechanical compatibility (4-DIP package, 7.62mm x 7.62mm footprint, 6.40mm maximum height)
• Lens configuration (clear, domed round lens)
• Regulatory compliance (RoHS3, REACH status)
• Product status (active production)

Only components meeting all these parameters are classified as direct parametric equivalents. No deviations in electrical, optical, or mechanical specifications are permitted for substitution.

Parameter Comparison

Engineering Selection Recommendations

The TLWR8901 is a direct parametric equivalent to the TLWR8902. Both components are manufactured by Vishay Semiconductor Opto Division within the TELUX™ series and maintain identical specifications across all electrical, optical, and mechanical parameters. Both parts carry active product status with full RoHS3 compliance and REACH unaffected designation, ensuring regulatory compatibility in current and future applications.

Selection between TLWR8902 and TLWR8901 may be based on inventory availability and supply chain considerations, as both components are functionally interchangeable within the specified 4-DIP through-hole package configuration.

Frequently Asked Questions (FAQ)

Q: Can TLWR8901 be used as a direct replacement for TLWR8902?

A: Yes. The TLWR8901 meets all substitution criteria, including identical forward voltage (2.2V), test current (70mA), wavelength specifications (615nm dominant, 624nm peak), luminous intensity (700mcd), viewing angle (90°), package form factor (4-DIP), and physical dimensions (7.62mm x 7.62mm x 6.40mm max height). Both components are ROHS3 compliant and REACH unaffected.

Q: Are there any differences in optical performance between these parts?

A: No. Both the TLWR8902 and TLWR8901 specify identical optical characteristics: 700mcd luminous intensity, 615nm dominant wavelength, 624nm peak wavelength, 90° viewing angle, and clear domed round lens configuration.

Q: Do these components require different PCB footprints?

A: No. Both parts use the identical 4-DIP (0.200", 5.08mm) package with matching 7.62mm x 7.62mm footprint dimensions and 6.40mm maximum height, ensuring direct PCB compatibility without layout modifications.

Q: What is the moisture sensitivity rating for these LEDs?

A: Both components carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage, handling, or assembly processes.

Q: Are both parts suitable for RoHS3 compliant applications?

A: Yes. Both TLWR8902 and TLWR8901 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component use.
