Substitute Part Grouping Explanation

Substitution of the TLHR5205 is determined by strict adherence to the following electrical and mechanical parameters:

Primary Compatibility Criteria:

Color: Red
Lens Size: 5mm, T-1 3/4
Mounting Type: Through Hole
Package / Case: Radial
Voltage - Forward (Vf) (Typ): 2V ±0.1V tolerance
Current - Test: 10mA to 20mA operating range
Wavelength - Dominant: 619nm to 626nm range
Wavelength - Peak: 632nm to 635nm range

Secondary Compatibility Considerations:

Millicandela Rating: 50mcd to 370mcd (brightness variation acceptable based on application requirements)
Viewing Angle: 15° to 50° (directional characteristics may vary)
Lens Transparency: Diffused or Clear (optical diffusion characteristics differ)
Height (Max): 6.35mm to 12.20mm (mechanical clearance dependent)

Substitute parts are grouped based on matching primary criteria while allowing variance in secondary parameters. Parts with identical electrical specifications but different lens transparency or brightness ratings remain functionally compatible for indication applications where exact optical characteristics are not critical.

Engineering Selection Recommendations

Primary Substitute (Highest Compatibility): TLHR5200 is the direct equivalent from the same manufacturer. It maintains identical electrical specifications (2V forward voltage, 10mA test current), identical wavelength characteristics (619nm dominant, 635nm peak), identical viewing angle (28°), and identical mechanical form factor (5mm T-1 3/4, 12.20mm height). The only variance is reduced brightness (50mcd versus 70mcd), which is acceptable for indication applications where exact luminous intensity is not critical. Product status is Active, ensuring long-term availability and supply chain stability.

Secondary Substitutes (Conditional Compatibility): LTL-307EE-012 and LTL-4224-002 maintain the 2V forward voltage specification and compatible wavelength range (623nm dominant). Both support higher test current (20mA) and provide comparable brightness (90mcd). These parts are suitable where increased current capacity is beneficial. Product status is Active.

HLMP-C223 provides the highest brightness option (170mcd) with compatible wavelength (626nm dominant) and viewing angle (25°), though forward voltage is reduced to 1.9V and test current is elevated to 20mA. This part is suitable for applications requiring enhanced visibility. Product status is Active.

MV8141A4R0 offers the highest brightness (370mcd) with compatible wavelength range (660nm peak) and wide viewing angle (40°), though forward voltage is significantly reduced to 1.7V. This part is suitable for high-brightness indication requirements. Product status is Active.

Not Recommended: LTL-4214 exhibits wavelength shift (657nm dominant, 697nm peak) outside the acceptable range and reduced brightness (19mcd). MV5152 is obsolete and exhibits color shift to orange. LTL-4294-012 exhibits color shift to red-orange. HLMP-3366 exhibits significant brightness reduction (13.8mcd) and height reduction (6.35mm).

All recommended substitutes maintain ROHS3 compliance and RoHS Unaffected status consistent with the original part.

Frequently Asked Questions (FAQ)

Q: Can TLHR5200 be used as a direct replacement for TLHR5205? A: Yes. TLHR5200 is the active equivalent from Vishay Semiconductor Opto Division with identical electrical and mechanical specifications. The only difference is reduced brightness (50mcd versus 70mcd), which is acceptable for standard indication applications.

Q: What is the primary difference between diffused and clear lens options? A: The TLHR5205 features a diffused lens, which scatters light over a wider area with reduced peak intensity. Clear lens alternatives (such as HLMP-C223 or LTL-307EE-012) provide more concentrated light output. Selection depends on application requirements for light distribution and visibility angle.

Q: Are forward voltage differences significant when substituting? A: Forward voltage differences of 0.1V to 0.3V are generally acceptable in indication applications. However, circuit design must accommodate the specified voltage range. HLMP-C223 (1.9V) and MV8141A4R0 (1.7V) operate at lower voltages than the original 2V specification and may require circuit adjustment.

Q: Can I use a higher brightness substitute if the original application requires 70mcd? A: Yes, higher brightness substitutes (such as MV8141A4R0 at 370mcd or HLMP-C215 at 300mcd) are compatible. However, circuit current limiting must be verified to prevent over-driving the LED. Test current specifications must be observed.

Q: What is the significance of wavelength specifications? A: Dominant wavelength (619nm to 626nm range) determines the perceived color. Peak wavelength indicates the spectral response curve. The TLHR5205 operates at 619nm dominant with 635nm peak. Substitutes within 619nm to 626nm dominant range maintain color consistency. Wavelengths above 630nm (such as LTL-4214 at 657nm) exhibit noticeable color shift toward deep red.

Q: Are all substitute parts RoHS compliant? A: Yes. All recommended substitute parts maintain ROHS3 compliance consistent with the original TLHR5205 specification.

Q: What packaging considerations apply to these substitutes? A: All listed parts maintain the T-1 3/4 (5mm) through-hole radial package. Height variations (6.35mm to 12.20mm) may affect mechanical clearance in confined spaces. Verify PCB layout and enclosure dimensions before final selection.

Q: Why is MV5152 not recommended despite similar specifications? A: MV5152 is classified as obsolete, creating supply chain risk. Additionally, it exhibits color shift to orange, which may not be acceptable for applications requiring red indication.
