MV7442 Equivalent & Substitute Parts Reference

Part Overview

The MV7442 is a green LED indicator manufactured by Everlight Electronics Co Ltd, designed for through-hole mounting applications. This T-1 3mm radial LED operates at 2.1V forward voltage with a 120mcd brightness rating and 570nm dominant wavelength. The component is classified as Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating.

Equivalent and substitute parts are necessary when the primary MV7442 becomes unavailable due to inventory constraints, supply chain disruptions, or end-of-life declarations. Alternative components meeting the same electrical and mechanical specifications ensure design continuity and production scheduling flexibility.

Substitute Part Grouping Explanation

Substitution logic for the MV7442 is determined by the following critical parameters:

Electrical Compatibility: Forward voltage (Vf) must remain within 2.1V ±0.15V range to ensure proper circuit operation without requiring redesign of current-limiting resistors. Test current of 20mA establishes the baseline operating condition.

Optical Characteristics: Dominant wavelength must fall within the green spectrum (560nm–575nm range). Peak wavelength and millicandela rating determine brightness perception and visibility in the target application.

Mechanical Compatibility: Lens size T-1 (3mm) and through-hole radial mounting are mandatory for PCB footprint compatibility. Height variation must not exceed ±1.5mm to prevent mechanical interference with enclosure or adjacent components.

Regulatory Compliance: All substitute parts must maintain RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1) to meet environmental and reliability standards.

Product Status: Active or Last Time Buy status is acceptable. Not For New Designs status indicates obsolescence and should be avoided for new production unless inventory constraints require temporary use.

Engineering Selection Recommendations

Tier 1 - Direct Electrical Equivalents (2.1V Forward Voltage):

HLMP-Y801-JPP00 (Broadcom Limited) and WP710A10CGCK (Kingbright) are electrically identical to MV7442 at 2.1V forward voltage with 20mA test current. Both maintain Active product status. HLMP-Y801-JPP00 offers higher brightness (310mcd) with narrower viewing angle (30°), suitable for applications requiring concentrated light output. WP710A10CGCK provides equivalent brightness (330mcd) with similar wavelength characteristics (570nm dominant). Height reduction (5.20mm and 5.90mm respectively versus 6.30mm) may require PCB layout verification for mechanical clearance.

LTL-4236N (Lite-On Inc.) operates at 2.1V but with reduced test current (10mA) and lower brightness (40mcd). This part is suitable only for applications where lower brightness is acceptable and current consumption reduction is beneficial. Active product status and extensive inventory (47,349 pcs) provide supply security.

Tier 2 - Voltage-Compensated Substitutes (2.2V Forward Voltage):

SSL-LX3044GC and SSL-LX3044SGC (Lumex Opto/Components Inc.) operate at 2.2V forward voltage, requiring circuit resistor recalculation to maintain 20mA test current. SSL-LX3044SGC (200mcd) provides brightness comparable to MV7442 (120mcd) with reduced height (4.60mm). Both maintain Active status and RoHS3 compliance. The 0.1V voltage increase necessitates verification that the power supply and current-limiting circuit can accommodate this variation without exceeding component ratings.

WP132XGC and WP710A10GC (Kingbright) also operate at 2.2V. WP132XGC offers 40mcd brightness with wider viewing angle (50°), while WP710A10GC provides identical brightness and wavelength to WP710A10CGCK but at 2.2V. Both require resistor adjustment.

Tier 3 - Obsolescence Alternatives:

SLR-343MC3F (Rohm Semiconductor) carries Not For New Designs status and should be used only for legacy product maintenance or temporary supply gaps. SLR-343PC3F is designated Last Time Buy, indicating imminent discontinuation, and should be avoided for new production.

WP710A10PGC (Kingbright) operates at 2.25V with significantly reduced brightness (12mcd) and shorter wavelength (557nm), making it unsuitable as a direct replacement except in applications specifically designed for lower brightness and yellow-green spectrum.

Compliance Verification:

All recommended substitutes maintain RoHS3 compliance and MSL 1 (unlimited) moisture sensitivity rating, ensuring compatibility with existing supply chain and manufacturing processes.

Frequently Asked Questions (FAQ)

Q: Can I use HLMP-Y801-JPP00 as a direct replacement for MV7442 without circuit modification?

A: Yes. Both parts operate at 2.1V forward voltage with 20mA test current, identical electrical characteristics. However, verify PCB mechanical clearance, as HLMP-Y801-JPP00 height is 5.20mm versus MV7442 at 6.30mm. The narrower viewing angle (30° versus 45°) may affect light distribution in the application.

Q: What is the impact of using a 2.2V forward voltage substitute like SSL-LX3044SGC?

A: The 0.1V increase requires recalculation of the current-limiting resistor to maintain 20mA test current. Using the original resistor value will reduce current flow and brightness. Verify that the power supply voltage and circuit design can accommodate the higher forward voltage without exceeding maximum ratings.

Q: Why is SLR-343MC3F marked "Not For New Designs"?

A: This designation indicates the manufacturer has discontinued active development and recommends against using this part in new product designs. It may be used for legacy product support or temporary supply solutions, but long-term availability is not guaranteed.

Q: Can I substitute WP710A10PGC for MV7442?

A: Not recommended. WP710A10PGC operates at 2.25V with significantly lower brightness (12mcd versus 120mcd) and different wavelength (557nm versus 570nm). This part is suitable only for applications specifically designed for lower brightness and yellow-green spectrum output.

Q: Which substitute offers the best brightness match to MV7442?

A: WP710A10CGCK (330mcd) and HLMP-Y801-JPP00 (310mcd) both exceed MV7442 brightness (120mcd). For applications requiring similar brightness levels, LTL-4236N (40mcd) or WP132XGC (40mcd) provide lower output. SSL-LX3044GC (100mcd) offers the closest brightness match below MV7442 specification.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts maintain RoHS3 compliance and MSL 1 moisture sensitivity rating, ensuring compatibility with environmental and regulatory requirements.

Q: What is the viewing angle impact when substituting HLMP-Y801-JPP00 (30°) for MV7442 (45°)?

A: The narrower viewing angle concentrates light output in a smaller cone. Applications requiring wide-angle illumination may experience reduced visibility. Verify the optical design accommodates the 15° reduction in viewing angle.

Q: Can I use LTL-4236N if I need to reduce power consumption?

A: Yes. LTL-4236N operates at 10mA test current versus MV7442 at 20mA, reducing power consumption by 50%. However, brightness is also reduced to 40mcd. This substitution is suitable only for applications where lower brightness is acceptable and power reduction is a design requirement.
