Equivalent & Substitute Parts for 17-21VRC/TR8(HT)

Part Overview

The 17-21VRC/TR8(HT) is a red surface mount LED manufactured by Everlight Electronics Co Ltd, designed for indication applications in 0805 (2012 Metric) package format. This part operates at 2V forward voltage with a 20mA test current and delivers 9 millicandela brightness with a 140° viewing angle. The device features a colorless clear lens with a rectangular flat-top design and is supplied in Tape & Reel packaging. As an active product with current inventory availability, equivalent substitute parts may be required for supply chain optimization, design flexibility, or inventory management purposes.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 17-21VRC/TR8(HT) is determined by strict equivalence across the following critical parameters:

Package compatibility: Both parts must use 0805 (2012 Metric) surface mount package format to ensure PCB footprint and assembly process compatibility.

Optical characteristics: Color (red), lens transparency (clear), and lens style (rectangle with flat top) must match exactly for visual indication consistency.

Electrical performance: Forward voltage (2V typical), test current (20mA), and millicandela rating (9mcd) must be identical to ensure circuit compatibility and brightness consistency.

Viewing angle: 140° specification must be maintained for application-specific visibility requirements.

Wavelength specifications: Dominant wavelength in the 625nm range and peak wavelength in the 635-640nm range are acceptable within the red LED spectrum for indication applications.

Mechanical dimensions: Overall size (2.00mm L x 1.25mm W) and maximum height must be compatible with PCB layout constraints.

Packaging format: Tape & Reel (TR) supply format must be maintained for automated assembly processes.

Parameter Comparison

Engineering Selection Recommendations

The SML-LX0805IC-TR (Lumex Opto/Components Inc.) is a direct parametric equivalent to the 17-21VRC/TR8(HT). Both parts meet identical specifications across all critical electrical, optical, and mechanical parameters required for red LED indication applications in 0805 surface mount format.

Both parts maintain Active product status, ensuring continued availability and manufacturer support. The SML-LX0805IC-TR carries ROHS3 compliance and REACH Unaffected status, meeting current environmental and regulatory requirements. The Lumex part features Moisture Sensitivity Level (MSL) 3 rating with 168-hour specification, appropriate for standard PCB assembly processes.

The peak wavelength difference (640nm vs 635nm) remains within the acceptable red LED spectrum for indication applications and does not affect functional compatibility. The SML-LX0805IC-TR maximum height of 1.20mm is lower than the 17-21VRC/TR8(HT) specification of 1.30mm, providing additional clearance margin for PCB layout and assembly.

Selection between these parts should be based on supply chain availability, lead time requirements, and inventory management objectives, as both parts are functionally and mechanically interchangeable.

Frequently Asked Questions (FAQ)

Q: Can the SML-LX0805IC-TR replace the 17-21VRC/TR8(HT) in existing designs?

A: Yes. Both parts share identical electrical specifications (2V forward voltage, 20mA test current), optical characteristics (9mcd, 140° viewing angle, red clear lens), and mechanical dimensions (0805 package, 2.00mm x 1.25mm footprint). No circuit modifications are required.

Q: Are there differences in brightness or color between these parts?

A: Both parts deliver 9 millicandela brightness with identical viewing angles and lens transparency. Peak wavelength specifications (640nm vs 635nm) fall within the standard red LED spectrum and produce visually equivalent indication performance.

Q: What is the impact of the height difference between these parts?

A: The SML-LX0805IC-TR has a maximum height of 1.20mm compared to 1.30mm for the 17-21VRC/TR8(HT). This 0.10mm difference provides additional clearance and does not create compatibility issues. Both parts fit within standard 0805 package height tolerances for PCB assembly.

Q: Are both parts suitable for automated assembly?

A: Yes. Both parts are supplied in Tape & Reel (TR) format, the standard packaging for automated pick-and-place assembly processes. Reel specifications and tape dimensions are consistent with 0805 component handling equipment.

Q: What compliance certifications apply to these parts?

A: The 17-21VRC/TR8(HT) carries EAR99 export classification and HTSUS code 8541.41.0000. The SML-LX0805IC-TR carries identical export and tariff classifications, plus ROHS3 compliance and REACH Unaffected status, meeting current environmental regulations.

Q: Can these parts be mixed in the same production batch?

A: Yes. Identical package format, electrical specifications, and optical characteristics allow both parts to be used interchangeably within the same PCB assembly without process modifications or rework.
