Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MV7344 are identified through parametric equivalence matching. The substitution logic is based on the following critical parameters that must remain constant across all equivalent components:

Optical Parameters: Color (Yellow), Lens Transparency (Clear), Millicandela Rating (375mcd), Peak Wavelength (590nm), and Viewing Angle (60°) establish the light output characteristics and must match exactly.

Electrical Parameters: Forward Voltage (2.1V typical) and Test Current (20mA) define the component's electrical operating point and must be identical.

Mechanical Parameters: Lens Style (Round with Domed Top), Lens Size (3mm T-1), Mounting Type (Through Hole), Package Type (Radial), and Maximum Height (6.30mm) ensure physical and functional compatibility with existing PCB designs and sockets.

Compliance Parameters: RoHS3 compliance status is required for regulatory equivalence in applicable markets.

Parts meeting all these criteria are classified as parametric equivalents and may be substituted without circuit redesign or board layout modification.

Parameter Comparison

Engineering Selection Recommendations

Both the MV7344 from Everlight Electronics Co Ltd and the MV7344 from Fairchild Semiconductor are parametric equivalents meeting all critical electrical, optical, and mechanical specifications. Both components are active products with ROHS3 compliance certification.

Primary Selection Criteria:

The Everlight MV7344 carries MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions during storage and handling. The Fairchild Semiconductor MV7344 carries MSL rating of 3 (168 Hours), requiring controlled storage conditions within 168 hours of package opening.

Selection between these equivalents should be based on:

1. Moisture Control Environment: If storage conditions cannot maintain MSL 3 requirements, the Everlight component with MSL 1 is the appropriate choice.

2. Inventory Availability: Fairchild Semiconductor currently maintains 9531 units in stock compared to 961 units for Everlight, providing higher availability for large-volume requirements.

3. Packaging Format: Fairchild Semiconductor supplies in Bulk packaging, while Everlight packaging specification is not provided. Verify packaging compatibility with receiving and assembly processes.

Both components are suitable for direct substitution in through-hole LED indicator circuits operating at 2.1V forward voltage with 20mA test current.

Frequently Asked Questions (FAQ)

Q: Can the MV7344 from Fairchild Semiconductor directly replace the MV7344 from Everlight Electronics in existing designs?

A: Yes. Both components are parametric equivalents with identical electrical characteristics (2.1V forward voltage, 20mA test current), optical properties (375mcd, 590nm peak wavelength, 60° viewing angle), and mechanical dimensions (3mm T-1 through-hole radial package, 6.30mm maximum height). Direct substitution is supported without circuit modification.

Q: What is the significance of the different MSL ratings between the two MV7344 variants?

A: MSL (Moisture Sensitivity Level) indicates storage and handling requirements. The Everlight MV7344 with MSL 1 has unlimited shelf life under normal conditions. The Fairchild Semiconductor MV7344 with MSL 3 requires use within 168 hours of package opening under controlled humidity conditions. Selection depends on your storage and assembly environment capabilities.

Q: Are both MV7344 variants suitable for RoHS3 compliant applications?

A: Yes. Both the Everlight and Fairchild Semiconductor MV7344 components carry ROHS3 compliance certification, meeting regulatory requirements for restricted substance elimination in applicable markets.

Q: What is the difference between the packaging specifications listed for these components?

A: The Fairchild Semiconductor MV7344 is specified as Bulk packaging, while the Everlight component packaging is not specified in the provided data. Confirm packaging format compatibility with your receiving, storage, and assembly processes before procurement.

Q: Can these components be used interchangeably in high-brightness indicator applications?

A: Yes. Both variants provide identical 375mcd brightness rating at 20mA test current with 590nm peak wavelength and 60° viewing angle, supporting equivalent performance in yellow LED indicator circuits.

Q: What are the key parameters that must match for LED substitution?

A: Critical matching parameters include color (Yellow), lens transparency (Clear), brightness rating (375mcd), forward voltage (2.1V), test current (20mA), peak wavelength (590nm), viewing angle (60°), package type (T-1 radial through-hole), and physical dimensions (3mm lens, 6.30mm maximum height). All these parameters must be identical for direct substitution.
