TLHR6205 Equivalent & Substitute Parts

Part Overview

The TLHR6205 is a red LED indicator from Vishay Semiconductor Opto Division, featuring a 5mm T-1 3/4 through-hole package with 619nm dominant wavelength and 70mcd brightness. This part is classified as obsolete, making equivalent substitutes necessary for new designs and ongoing production requirements. The clear lens design and 28° viewing angle make it suitable for standard indication applications requiring moderate brightness and directional visibility.

Substitute Part Grouping Explanation

Substitution for the TLHR6205 is determined by the following critical parameters:

Color: Red (619-640nm wavelength range acceptable)
Lens Transparency: Clear (diffused variants excluded for direct substitution)
Package: T-1 3/4 through-hole radial configuration
Forward Voltage: 1.8V to 2.1V range
Brightness: 13.8mcd to 600mcd (application-dependent selection)
Viewing Angle: 15° to 60° (application-dependent)
Compliance: ROHS3 compliant, EAR99 classification

Substitute parts are grouped into two categories:

Category A - Direct Mechanical & Electrical Compatibility: Parts maintaining identical package geometry, forward voltage within ±0.2V, and clear lens transparency. These include HLMP-3366, HLMP-C115, HLMP-C215, HLMP-C223, LTL-307EE-012, and LTL-4224-002.

Category B - Functional Equivalents with Parameter Variations: Parts with compatible through-hole mounting and red wavelength but differing in brightness, viewing angle, or forward voltage. These include TLHR6405, LTL-4214, and LTL-4294-012.

Engineering Selection Recommendations

For Direct Replacement (Identical Electrical Behavior)

LTL-307EE-012 and LTL-4224-002 from Lite-On provide the closest electrical match with 2V forward voltage and 10-20mA test current range. Both maintain clear lens transparency and red wavelength specification. LTL-307EE-012 offers 90mcd brightness with 40° viewing angle, while LTL-4224-002 provides the same brightness with narrower 16° viewing angle. Both are active products with ROHS3 compliance.

For Lower Forward Voltage Applications

HLMP-C115, HLMP-C215, and HLMP-C223 from Broadcom operate at 1.8-1.9V forward voltage, reducing power consumption by approximately 5-10% compared to the TLHR6205. These parts accommodate 20mA test current and offer brightness options from 170mcd to 600mcd. HLMP-C223 provides the closest brightness match to TLHR6205 at 170mcd with 25° viewing angle.

For Brightness-Matched Selection

HLMP-C223 (170mcd, 25° viewing angle) provides the closest brightness and viewing angle match to TLHR6205 (70mcd, 28° viewing angle) among active products. LTL-307EE-012 (90mcd, 40° viewing angle) offers comparable brightness with slightly wider viewing angle.

Compliance & Availability

All recommended substitutes maintain ROHS3 compliance and EAR99 classification. Lite-On parts are available in tape & reel packaging for automated assembly. Broadcom parts are available in bulk packaging. Vishay TLHR6405 remains available as an active product but features diffused lens transparency, unsuitable for direct replacement in applications requiring clear lens characteristics.

Frequently Asked Questions (FAQ)

Q: Can TLHR6405 directly replace TLHR6205?

A: TLHR6405 shares identical manufacturer, package, and forward voltage but features diffused lens transparency versus the clear lens of TLHR6205. Diffused lenses produce wider viewing angles (60° vs 28°) and lower brightness (14mcd vs 70mcd). Selection depends on application requirements for lens clarity and brightness distribution.

Q: What is the impact of forward voltage differences between substitutes?

A: TLHR6205 operates at 2V typical forward voltage. Broadcom HLMP series parts operate at 1.8-1.9V, reducing circuit power consumption by approximately 5-10%. Lite-On LTL-4214 operates at 2.1V, requiring slightly higher circuit voltage. Forward voltage differences of ±0.2V are within acceptable tolerance for most indicator applications but may require circuit verification for precision current-limiting designs.

Q: Are Lite-On and Broadcom parts mechanically interchangeable?

A: All recommended substitutes maintain T-1 3/4 through-hole radial package configuration and are mechanically interchangeable on standard PCB layouts. Height variations (6.35mm to 9.85mm) are within typical PCB clearance tolerances. Verify specific application clearance requirements for height-constrained designs.

Q: Which substitute offers the best brightness match?

A: HLMP-C223 (170mcd) provides the closest brightness match among active products. LTL-307EE-012 (90mcd) offers moderate brightness with good availability. HLMP-C115 (600mcd) is available for applications requiring significantly higher brightness but operates at narrower 15° viewing angle.

Q: Can I use MV5152 as a substitute?

A: MV5152 is classified as obsolete and features orange color (not red) with unspecified dominant wavelength. It is not recommended as a direct substitute for TLHR6205 red indication applications. Use only if application specifically requires orange indication.

Q: What packaging options are available for production?

A: Lite-On parts (LTL-307EE-012, LTL-4224-002, LTL-4294-012) are available in tape & reel packaging suitable for automated pick-and-place assembly. Broadcom parts (HLMP-C115, HLMP-C215, HLMP-C223) are available in bulk packaging. Vishay TLHR6405 is available in bulk packaging. Verify packaging requirements with procurement for production volume and assembly method.
