TLHR6201 Equivalent & Substitute Parts

Part Overview

The TLHR6201 is a red LED indicator manufactured by Vishay Semiconductor Opto Division, designed for through-hole mounting applications. This part operates at 2V forward voltage with a 30mcd brightness rating and features a 5mm T-1 3/4 clear lens with a 28° viewing angle. The TLHR6201 is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. Substitute parts must maintain compatibility with the original electrical specifications, mechanical form factor, and mounting requirements while offering active product status and continued availability.

Mounting type: Through hole radial configuration
Color: Red LED indication
Lens transparency: Clear
Lens style: Round with domed top
Package / Case: Radial
RoHS compliance: ROHS3 Compliant

Electrical Operating Parameters:

Forward voltage (Vf): 2V nominal operation
Test current: 10mA to 20mA range
Wavelength compatibility: Red spectrum (619nm to 640nm dominant wavelength)

Performance Characteristics:

Millicandela rating: 25mcd to 600mcd (application-dependent selection)
Viewing angle: 15° to 50° (application-dependent selection)

Engineering Selection Recommendations

Direct Electrical Equivalents (2V / 10mA Operation):

SLR-56VC3F and SLR-56VCT32 from Rohm Semiconductor provide the closest electrical match to the TLHR6201, operating at 2V forward voltage with 10mA test current. Both parts maintain 25mcd brightness rating and 630nm dominant wavelength within the red spectrum. These parts are active products with ROHS3 compliance and offer the most straightforward replacement path for existing circuit designs without modification.

Functional Alternatives (2V Operation with Higher Test Current):

LTL-307EE-012 from Lite-On Inc. operates at 2V with 20mA test current, providing 90mcd brightness and 623nm wavelength. This part is suitable for applications requiring higher brightness while maintaining the original 2V supply voltage. SSL-LX5093IT-11 from Lumex Opto/Components Inc. offers 80mcd at 2V/20mA operation with 30° viewing angle, providing moderate brightness increase for visibility-critical applications.

Lower Voltage Alternatives (1.8V to 1.9V Operation):

Broadcom Limited parts HLMP-C115, HLMP-C215, HLMP-C223, and HLMP-3366 operate at reduced forward voltages (1.8V to 1.9V) with 20mA test current. These parts are suitable only for applications where circuit design permits lower supply voltage operation. HLMP-C115 delivers 600mcd brightness for high-visibility requirements, while HLMP-C223 provides 170mcd at moderate brightness levels.

Selection Criteria:

For direct replacement without circuit modification: SLR-56VC3F or SLR-56VCT32
For increased brightness at 2V operation: LTL-307EE-012 or SSL-LX5093IT-11
For reduced voltage operation: HLMP-C223 or HLMP-C215
All recommended substitutes maintain ROHS3 compliance and through-hole radial mounting compatibility

Frequently Asked Questions (FAQ)

Q: Can HLMP-C115 replace TLHR6201 directly in existing circuits?

A: HLMP-C115 operates at 1.8V forward voltage compared to TLHR6201's 2V specification. Direct substitution requires circuit verification to confirm the lower voltage is compatible with existing current-limiting resistor values and power supply design. The part also requires 20mA test current versus the original 10mA specification.

Q: What is the difference between SLR-56VC3F and SLR-56VCT32?

A: Both parts are electrically identical, operating at 2V/10mA with 25mcd brightness and 630nm wavelength. The primary difference is packaging: SLR-56VC3F is supplied in bulk packaging, while SLR-56VCT32 is supplied in tape and box format. Selection depends on procurement and assembly requirements.

Q: Are all substitute parts RoHS compliant?

A: Yes, all substitute parts listed maintain ROHS3 compliance, matching the original TLHR6201 specification. All parts are also REACH unaffected and classified under ECCN EAR99.

Q: Can I use SSL-LX5093HT instead of SSL-LX5093IT-11?

A: Both parts are from Lumex Opto/Components Inc. and operate at 2V/20mA. SSL-LX5093HT provides 25mcd brightness, while SSL-LX5093IT-11 provides 80mcd brightness. Selection depends on required brightness level for the application. Both maintain identical 5mm T-1 3/4 form factor and 30° viewing angle.

Q: What viewing angle should I select for my application?

A: The TLHR6201 specifies 28° viewing angle. Substitute parts range from 15° (narrow, focused indication) to 50° (wide, diffuse indication). Select based on application requirements: narrow angles (15°-25°) for focused indicator positions, moderate angles (28°-40°) for general indication, and wide angles (50°) for omnidirectional visibility.

Q: Does height variation affect PCB layout compatibility?

A: Yes. The TLHR6201 maximum height is 9.10mm. Substitute parts range from 6.35mm to 9.85mm. Verify PCB clearance requirements before selection. Parts with lower height (HLMP-3366 at 6.35mm) may require PCB layout adjustment if original design assumed 9.10mm clearance.

Q: Which substitute offers the closest brightness match to TLHR6201?

A: SLR-56VC3F and SLR-56VCT32 provide 25mcd brightness, closest to the original 30mcd specification. For higher brightness requirements, SSL-LX5093IT-11 offers 80mcd and LTL-307EE-012 offers 90mcd, both at 2V operation.
