TLHR5201 Equivalent & Substitute Parts

Part Overview

The TLHR5201 is a red diffused T-1 3/4 through-hole LED manufactured by Vishay Semiconductor Opto Division, designed for indication applications with a dominant wavelength of 619nm and peak wavelength of 635nm. This part is classified as obsolete, making equivalent and substitute parts necessary for new designs and ongoing production requirements. The TLHR5201 operates at 2V forward voltage with a 10mA test current and delivers 60mcd brightness through its diffused lens design.

Substitute Part Grouping Explanation

Substitution of the TLHR5201 is determined by the following critical parameters:

Lens Size & Mounting: All substitutes must maintain 5mm T-1 3/4 through-hole radial package compatibility
Color & Wavelength: Red color family with dominant wavelength in the 619–660nm range
Electrical Characteristics: Forward voltage tolerance (1.7V–2.1V) and test current (10–20mA)
Optical Performance: Millicandela rating and viewing angle must support the intended indication application
Compliance: ROHS3 compliance and EAR99 ECCN classification maintained across all substitutes

Substitutes are grouped into two categories based on lens transparency and brightness characteristics:

Category A – Diffused Lens (Direct Replacement)

TLHR5200: Active status, diffused lens, 50mcd, maintains 2V/10mA electrical profile

Category B – Clear Lens Alternatives (Functional Equivalents)

HLMP-3366, HLMP-C215, HLMP-C223: Broadcom clear lens options with varying brightness and viewing angles
LTL-307EE-012, LTL-4224-002: Lite-On clear lens options with 90mcd brightness
MV8141A4R0: Everlight high-brightness option at 370mcd with lower forward voltage (1.7V)

Engineering Selection Recommendations

Primary Recommendation: TLHR5200

The TLHR5200 is the direct equivalent for TLHR5201 replacement. Both parts share identical electrical characteristics (2V/10mA), matching lens size (5mm T-1 3/4), diffused lens design, and wavelength profile (619nm dominant). The TLHR5200 maintains active product status with full ROHS3 compliance and equivalent inventory availability. The only difference is a 10mcd reduction in brightness (50mcd vs. 60mcd), which remains within acceptable tolerance for most indication applications.

Secondary Recommendations for Clear Lens Applications:

When clear lens transparency is acceptable or preferred:

LTL-307EE-012 or LTL-4224-002: Maintain 2V forward voltage matching the original part. LTL-307EE-012 offers 40° viewing angle with 90mcd brightness; LTL-4224-002 provides narrower 16° viewing angle at equivalent brightness. Both operate at 20mA test current.
HLMP-C223: Broadcom alternative with 170mcd brightness, 25° viewing angle, and 1.9V forward voltage. Suitable for applications requiring higher brightness than TLHR5201 with moderate viewing angle.
MV8141A4R0: High-brightness option at 370mcd with lowest forward voltage (1.7V) and wide 40° viewing angle. Requires circuit redesign for lower voltage operation but provides superior optical performance.

All recommended substitutes maintain ROHS3 compliance, EAR99 ECCN classification, and through-hole radial packaging required for direct PCB mounting compatibility.

Frequently Asked Questions (FAQ)

Q: Can TLHR5200 directly replace TLHR5201 without circuit modification?

A: Yes. The TLHR5200 maintains identical forward voltage (2V), test current (10mA), and package configuration (5mm T-1 3/4 radial). The 10mcd brightness reduction (60mcd to 50mcd) is typically imperceptible in indication applications and does not require circuit changes.

Q: What is the difference between diffused and clear lens options?

A: Diffused lenses scatter light over a wider area with softer appearance, while clear lenses concentrate light with sharper intensity. TLHR5200 maintains the diffused design of TLHR5201. Clear lens alternatives (HLMP series, LTL series, MV8141A4R0) provide higher brightness concentration but different visual characteristics. Selection depends on application requirements for light distribution and intensity.

Q: Can I use HLMP-C215 or HLMP-C223 as direct replacements?

A: These are functional equivalents, not direct replacements. Both operate at 1.9V forward voltage (vs. 2V) and require 20mA test current (vs. 10mA). Circuit redesign is necessary to accommodate higher current draw. HLMP-C223 (170mcd, 25° viewing angle) provides closer brightness match to TLHR5201 than HLMP-C215 (300mcd, 15° viewing angle).

Q: What is the advantage of MV8141A4R0?

A: MV8141A4R0 delivers the highest brightness (370mcd) among all substitutes with the widest viewing angle (40°). The 1.7V forward voltage is the lowest, reducing power consumption. However, circuit redesign is required to accommodate lower voltage and higher current (20mA) operation.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All listed substitutes maintain ROHS3 compliance and EAR99 ECCN classification, meeting regulatory requirements for new designs and production environments.

Q: What packaging formats are available?

A: TLHR5200, HLMP series, and MV8141A4R0 are available in bulk packaging. LTL-307EE-012 and LTL-4224-002 are supplied in Tape & Reel format. Packaging selection depends on production volume and assembly requirements.

Q: Can I substitute red-orange LTL-4294-012 for red TLHR5201?

A: LTL-4294-012 is a red-orange variant (621nm dominant wavelength) with identical electrical characteristics (2V/20mA) and brightness (90mcd). Substitution is possible only if application tolerates color shift from pure red to red-orange. Visual appearance will differ noticeably.
