Engineering Selection Recommendations

Primary Substitutes (2V Forward Voltage Class):

HLMP-6500 and HLMP-6500-F001S are the closest electrical equivalents to the MV6400A, both featuring 2.1V forward voltage and 10mA test current. HLMP-6500 maintains the flat axial lead configuration identical to the original part. HLMP-6500-F001S provides a right-angle bend variant for applications requiring different PCB mounting geometry. Both parts are active products with ROHS3 compliance and equivalent mechanical dimensions.

Alternative Substitutes (2V Forward Voltage Class):

HLMP-6505 operates at 2.1V forward voltage with identical through-hole axial mounting but features a clear lens instead of diffused. This part delivers 40mcd brightness with a narrower 28° viewing angle, suitable for applications requiring higher intensity and directional indication.

Secondary Substitutes (5V Forward Voltage Class):

HLMP-6800 and HLMP-6820 operate at 5V forward voltage and are suitable only for circuits designed for higher voltage operation. HLMP-6800 provides 5mcd brightness with 90° viewing angle. HLMP-6820 delivers 2mcd brightness, the lowest in the substitute group. These parts require circuit redesign and are not direct drop-in replacements for 2V applications.

All substitute parts from Broadcom Limited are active products with ROHS3 compliance and REACH unaffected status, ensuring regulatory compliance and long-term availability.

Frequently Asked Questions (FAQ)

Q: Can HLMP-6500 directly replace MV6400A without circuit modification?

A: Yes. HLMP-6500 operates at 2.1V forward voltage, within acceptable tolerance of the original 2V specification. Both parts share identical mounting type (through-hole axial), package configuration (flat leads), and mechanical dimensions (2.92mm height). The 7mcd brightness is higher than the original 3mcd, and the 90° viewing angle is wider than the original 50°, both acceptable for indicator applications.

Q: What is the difference between HLMP-6500 and HLMP-6500-F001S?

A: Both parts operate at identical electrical specifications (2.1V, 10mA, 7mcd). The primary difference is the lead configuration: HLMP-6500 features flat axial leads for straight through-hole mounting, while HLMP-6500-F001S features a right-angle bend (2.54mm center) for applications requiring perpendicular PCB mounting geometry.

Q: Why are HLMP-6800 and HLMP-6820 listed as substitutes if they operate at 5V?

A: These parts are listed as substitutes only for applications where circuit voltage has been redesigned to 5V operation. They are not suitable for direct replacement in 2V circuits. Selection depends on the specific application voltage requirement and circuit design flexibility.

Q: What is the brightness difference between MV6400A and substitute parts?

A: MV6400A delivers 3mcd at 2V. HLMP-6500 and HLMP-6500-F001S deliver 7mcd at 2.1V (2.3x brighter). HLMP-6505 delivers 40mcd at 2.1V (13x brighter). HLMP-6800 delivers 5mcd at 5V (1.7x brighter). HLMP-6820 delivers 2mcd at 5V (0.67x dimmer). Brightness selection depends on application requirements.

Q: Are all substitute parts RoHS compliant?

A: Yes. All Broadcom Limited substitute parts listed are ROHS3 compliant. The original MV6400A RoHS status is not specified in available documentation.

Q: What is the viewing angle difference between MV6400A and substitutes?

A: MV6400A features a 50° viewing angle. HLMP-6500, HLMP-6500-F001S, HLMP-6800, and HLMP-6820 all feature 90° viewing angles (wider, omnidirectional). HLMP-6505 features a 28° viewing angle (narrower, directional). Viewing angle selection depends on the specific application's optical requirements.
