Voltage - Forward (Vf): 2V nominal (allows ±0.2V tolerance range)
Current - Test: 20mA nominal (allows ±5mA tolerance range)
Wavelength - Peak: 635nm ±10nm (red spectrum compatibility)

Secondary Compatibility Criteria:

Millicandela rating: 90mcd minimum (maintains brightness within acceptable range)
Viewing angle: 16° to 40° (maintains directional characteristics)

Engineering Selection Recommendations

Direct Substitutes (Electrical and Optical Compatibility):

LTL-307EE-012 and LTL-4224-002 from Lite-On Inc. are the closest electrical equivalents to the MV6752. Both operate at 2V forward voltage with 20mA test current and 90mcd brightness at 635nm peak wavelength. Both are RoHS3 compliant and active products with established supply chains. LTL-307EE-012 offers a wider 40° viewing angle, while LTL-4224-002 maintains a narrower 16° viewing angle. Selection between these depends on the specific application's optical requirements.

HLMP-C223 from Broadcom Limited operates at 1.9V forward voltage with identical 20mA test current and offers higher brightness at 170mcd. The 1.9V specification is within acceptable tolerance of the 2V original specification. This part is RoHS3 compliant and active. The slightly higher brightness may require circuit validation in brightness-sensitive applications.

Functional Alternatives (Electrical Compatibility with Parameter Variations):

SLR-56VC3F and SLR-56VCT32 from Rohm Semiconductor operate at 2V forward voltage but with reduced test current of 10mA and lower brightness of 25mcd. These parts are suitable for applications where lower brightness is acceptable or where current draw reduction is beneficial. Both are RoHS3 compliant and active products.

LTL-4214 from Lite-On Inc. operates at 2.1V forward voltage with 10mA test current and 19mcd brightness. The 2.1V specification is within acceptable tolerance. This part is suitable for applications tolerating lower brightness and reduced current draw.

Limited Compatibility (Voltage or Optical Variations):

4302H1-5V and 4302H1-12V from Visual Communications Company operate at 5V and 12V respectively, requiring significant circuit redesign. These parts feature diffused lens transparency rather than clear, altering optical characteristics. Selection of these parts is appropriate only when circuit voltage specifications differ from the original 2V design.

HLMP-D155 from Broadcom Limited operates at 1.7V forward voltage with significantly reduced test current of 1mA and brightness of 10mcd. This part is suitable only for low-power indicator applications and requires circuit validation.

Compliance and Availability:

All recommended substitute parts carry RoHS3 compliance and REACH unaffected status, meeting current regulatory requirements. All substitute parts listed are active products with established inventory levels, ensuring long-term availability compared to the obsolete MV6752.

Frequently Asked Questions (FAQ)

Q: Can LTL-307EE-012 directly replace MV6752 without circuit modification?

A: LTL-307EE-012 is electrically compatible with MV6752, operating at identical 2V forward voltage and 20mA test current. The 90mcd brightness is slightly lower than the original 100mcd specification. The wider 40° viewing angle compared to the original 28° may affect optical performance in applications requiring narrow beam characteristics. Circuit validation is recommended for brightness-critical applications.

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

A: Clear lens transparency provides direct light transmission with minimal scattering, maintaining the LED's specified viewing angle and brightness characteristics. Diffused lens transparency scatters light across a wider area, reducing peak brightness but increasing the effective viewing angle. The MV6752 uses clear transparency; substitutes with diffused lenses alter optical performance and require application validation.

Q: Are the 4302H1 series parts suitable replacements?

A: The 4302H1-5V and 4302H1-12V parts operate at significantly higher forward voltages (5V and 12V respectively) compared to the MV6752's 2V specification. These parts require complete circuit redesign and are not suitable as direct replacements. They are appropriate only when the application circuit operates at 5V or 12V supply voltages.

Q: How do viewing angle differences affect substitution?

A: The MV6752 specifies a 28° viewing angle. Substitute parts range from 16° to 60°. Narrower viewing angles (16°) concentrate light in a specific direction, suitable for focused indicator applications. Wider viewing angles (40°-60°) distribute light across a broader area, suitable for general indication. Application requirements determine acceptable viewing angle ranges.

Q: What does "Product Status: Active" mean for substitution purposes?

A: Active product status indicates the part is currently manufactured and supported by the supplier with established supply chains and long-term availability. The MV6752's obsolete status makes active substitute parts necessary for ongoing production. All recommended substitutes carry active status, ensuring component availability for future production runs and maintenance applications.

Q: Can HLMP-C223 replace MV6752 despite the 1.9V forward voltage difference?

A: HLMP-C223 operates at 1.9V forward voltage, which is within acceptable tolerance of the MV6752's 2V specification (±0.1V variation). The part maintains identical 20mA test current and offers higher brightness at 170mcd. Circuit validation is recommended to confirm that the slightly lower forward voltage does not affect circuit performance, particularly in current-limiting resistor calculations.

Q: What packaging differences exist between substitute parts?

A: The MV6752 uses radial through-hole packaging. All substitute parts maintain identical T-1 3/4 (5mm) form factor and radial through-hole mounting. Packaging variations include Bulk, Tape & Reel (TR), and Tape & Box (TB) formats, which affect procurement and handling but do not impact electrical or mechanical compatibility. Selection depends on production volume and assembly process requirements.

Q: Are there brightness considerations when selecting substitutes?

A: The MV6752 specifies 100mcd brightness. Substitute parts range from 8mcd to 170mcd. Lower brightness parts (8-25mcd) are suitable for applications where reduced power consumption or lower light output is acceptable. Higher brightness parts (170mcd) may require circuit validation to confirm that increased light output does not cause optical saturation or exceed application requirements. Brightness selection depends on specific application visibility requirements.
