MV64520 Equivalent & Substitute Parts

Part Overview

The MV64520 is a green LED indicator in T-1 3/4 (5mm) through-hole radial package manufactured by onsemi. This component is designed for discrete LED indication applications with a forward voltage of 2.2V and 25mcd brightness rating. The product is currently obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. Suitable alternatives must maintain compatibility with the T-1 3/4 form factor, through-hole mounting, and similar electrical characteristics to ensure direct replacement capability.

Substitute Part Grouping Explanation

Substitution for the MV64520 is determined by the following critical parameters:

Primary Compatibility Criteria:

Lens size: 5mm, T-1 3/4 form factor
Mounting type: Through hole radial configuration
Color: Green
Voltage - Forward (Vf): 2.2V nominal (allows ±0.1V tolerance)
Current - Test: 20mA nominal
Package / Case: Radial

Secondary Consideration Parameters:

Lens transparency: Clear preferred for direct visual indication
Millicandela rating: 25mcd minimum for equivalent brightness
Viewing angle: 35° nominal (range 15° to 60° acceptable for general indication)
Wavelength - Peak: 562nm to 572nm range (green spectrum)
Height (Max): 8.89mm to 10.08mm (PCB clearance compatibility)

Substitutes are grouped into two categories: direct electrical equivalents (matching 2.2V forward voltage and 20mA test current) and parametric equivalents (matching form factor and mounting with acceptable electrical variations).

Engineering Selection Recommendations

Direct Electrical Equivalents (Recommended Primary Substitutes):

HLMP-C523-J0002 (Broadcom Limited) and SSL-LX5093GT-11 (Lumex Opto/Components Inc.) are the preferred substitutes. Both maintain the exact 2.2V forward voltage and 20mA test current specifications of the MV64520. HLMP-C523-J0002 is actively produced with RoHS3 compliance and higher brightness (170mcd), suitable for applications requiring enhanced visibility. SSL-LX5093GT-11 offers moderate brightness (50mcd) with active product status and RoHS3 compliance. Both are available in clear lens T-1 3/4 through-hole packages with compatible physical dimensions.

Secondary Electrical Equivalents:

LTL-307GE-012 and LTL-4234-012 (Lite-On Inc.) operate at 2.1V forward voltage with 20mA test current, representing a 0.1V reduction from the MV64520 specification. Both are actively produced with RoHS3 compliance. LTL-307GE-012 provides 60mcd brightness with 40° viewing angle, closely matching the original viewing angle. LTL-4234-012 offers the same brightness but with a narrower 16° viewing angle. These parts are suitable for applications with flexible voltage tolerance.

Parametric Equivalents (Limited Substitution):

Z-212G (JKL Components Corp.) matches the 2.2V forward voltage and 25mcd brightness but operates at 10mA test current and features a taller 14.60mm height. This part is suitable only for applications where reduced current draw is acceptable and PCB clearance permits the increased height. RoHS non-compliance status limits use in regulated environments.

SLR-56MC3F (Rohm Semiconductor) operates at 2.1V with reduced 10mA test current and is marked "Not For New Designs," limiting its application to legacy system maintenance only.

Not Recommended for Direct Substitution:

4302H5-5V and 4302H5-12V (Visual Communications Company - VCC) feature significantly different electrical characteristics (5V and 12V forward voltage respectively) and diffused lens transparency. These parts are suitable only for applications specifically designed for higher voltage operation and diffused indication.

MV5452 (onsemi) is electrically identical to MV64520 but shares the same obsolete product status, offering no advantage for long-term supply continuity.

Frequently Asked Questions (FAQ)

Q: Can HLMP-C523-J0002 directly replace MV64520 in existing designs?

A: Yes. HLMP-C523-J0002 maintains identical forward voltage (2.2V) and test current (20mA) specifications. Physical dimensions are compatible (8.91mm height vs. 8.89mm original). The higher brightness (170mcd vs. 25mcd) may increase visibility but does not affect circuit compatibility. RoHS3 compliance provides regulatory advantage over the obsolete MV64520.

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

A: Clear lens LEDs provide directional light output with higher brightness concentration in the viewing angle. Diffused lens LEDs scatter light more broadly, reducing peak brightness but improving visibility from wider angles. The MV64520 uses clear lens; substitutes with diffused lenses (4302H5 series) are not direct replacements unless the application specifically requires diffused output.

Q: Are Lite-On LTL series parts compatible with MV64520?

A: LTL-307GE-012 and LTL-4234-012 are compatible with minor voltage tolerance. Both operate at 2.1V (0.1V below MV64520 specification) with identical 20mA test current. This 0.1V reduction is within typical LED forward voltage tolerance ranges. Both parts are actively produced with RoHS3 compliance, making them suitable long-term alternatives.

Q: Why do some substitutes have different millicandela ratings?

A: Millicandela (mcd) rating indicates brightness intensity. The MV64520 is rated at 25mcd. Substitutes range from 8mcd to 170mcd depending on lens design and LED chip specifications. Higher mcd ratings (HLMP-C523-J0002 at 170mcd) provide enhanced visibility but do not affect electrical circuit compatibility. Selection should consider application visibility requirements.

Q: Can I use 4302H5-5V or 4302H5-12V as substitutes?

A: No, not as direct replacements. These parts operate at 5V and 12V forward voltage respectively, compared to MV64520's 2.2V specification. They are suitable only for circuits specifically designed for higher voltage operation. Using them in 2.2V circuits will result in insufficient LED illumination or circuit malfunction.

Q: What does "Not For New Designs" status mean for SLR-56MC3F?

A: This designation indicates the manufacturer (Rohm Semiconductor) no longer recommends this part for new product development. While SLR-56MC3F may be used for legacy system maintenance or repair, it should not be selected for new designs due to uncertain long-term availability and potential future discontinuation.

Q: Are there RoHS compliance differences between substitutes?

A: Yes. HLMP-C523-J0002, LTL-307GE-012, LTL-4234-012, SLR-56MC3F, and SSL-LX5093GT-11 are all RoHS3 compliant. Z-212G is RoHS non-compliant, limiting its use in regulated industries and export markets. MV64520 and MV5452 predate RoHS requirements. For new designs and regulated applications, select RoHS3 compliant alternatives.

Q: How do viewing angles affect substitution decisions?

A: Viewing angle determines the cone of light visibility. MV64520 specifies 35°. Substitutes range from 15° (narrow, directional) to 60° (wide, diffuse). Narrower angles concentrate brightness in a specific direction; wider angles provide visibility from more positions. Selection depends on application requirements. For general indication panels, 30° to 40° angles are typically suitable.
