MV57154 Equivalent & Substitute Parts Reference

Part Overview

The MV57154 is a red diffused LED indicator manufactured by Everlight Electronics Co Ltd, designed for through-hole mounting applications. This T-1 3/4 (5mm) form factor LED operates at 2V forward voltage with a 10mA test current and delivers 8mcd luminous intensity. The component is classified as Active product status and maintains full ROHS3 compliance with unlimited moisture sensitivity rating (MSL 1).

Substitute parts are necessary when the MV57154 experiences supply constraints, extended lead times, or when design requirements permit operation within the electrical and mechanical tolerances of alternative qualified components. The Broadcom HLMP-3351 series provides functionally equivalent alternatives with compatible physical dimensions and mounting characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MV57154 is determined by strict alignment of the following critical parameters:

Physical Compatibility Parameters:

• Lens size must be 5mm, T-1 3/4 form factor
• Mounting type must be through-hole radial configuration
• Maximum height must not exceed 6.35mm
• Lens color must be red with diffused transparency

Electrical Compatibility Parameters:

• Forward voltage (Vf) must operate within circuit design tolerance (MV57154 nominal 2V)
• Test current rating must be 10mA
• Viewing angle must be 50°
• Wavelength peak must fall within red spectrum (630nm range)

Compliance Parameters:

• RoHS3 compliance required
• MSL rating of 1 (Unlimited) required
• Active product status required

The Broadcom HLMP-3351 series (base part HLMP-3351, variants HLMP-3351-D0000, and HLMP-3351-D0002) satisfy all physical mounting and compliance requirements. Electrical parameters show minor variations in forward voltage (1.9V vs 2V) and luminous intensity (2.1mcd to 5.4mcd depending on variant), which remain within acceptable substitution tolerance for standard indication applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: HLMP-3351-D0000

The HLMP-3351-D0000 variant is the preferred substitute for the MV57154. This component maintains identical physical dimensions (5mm T-1 3/4, 6.35mm height), mounting configuration (through-hole radial), and optical characteristics (red diffused lens, 50° viewing angle). Both components are Active status products with ROHS3 compliance and MSL 1 rating. The forward voltage differential (1.9V vs 2V) is within standard circuit design tolerance for LED indication applications. Current inventory of 19,677 pieces provides supply security.

Secondary Substitute: HLMP-3351

The base HLMP-3351 part number offers higher luminous intensity (5.4mcd) compared to the HLMP-3351-D0000 variant (2.1mcd), making it suitable for applications requiring increased brightness. Physical and compliance characteristics remain identical. Bulk packaging is available with 5,267 pieces in stock.

Tertiary Substitute: HLMP-3351-D0002

The HLMP-3351-D0002 variant provides identical electrical and physical specifications to the HLMP-3351-D0000 but is supplied in Cut Tape (CT) packaging format. This option is appropriate for automated assembly processes. Stock availability is 10,091 pieces.

All three Broadcom substitutes maintain full compatibility with the MV57154 across compliance certifications (ROHS3, MSL 1, REACH Unaffected status for HLMP variants), product status (Active), and mechanical form factor requirements.

Frequently Asked Questions (FAQ)

Q: Can HLMP-3351 series parts directly replace MV57154 in existing PCB designs?

A: Yes. The HLMP-3351 series maintains identical physical dimensions (5mm T-1 3/4 form factor, 6.35mm maximum height) and through-hole radial lead configuration. PCB footprints and mounting holes are compatible without modification.

Q: What is the significance of the forward voltage difference (2V vs 1.9V)?

A: The 0.1V difference is within standard tolerance for LED indication circuits. Circuit designs using current-limiting resistors will accommodate this variation. For precision applications requiring exact voltage matching, circuit validation is necessary based on specific design parameters not provided in this reference.

Q: How do the luminous intensity variations (8mcd, 5.4mcd, 2.1mcd) affect substitution?

A: Luminous intensity determines brightness output. The MV57154 at 8mcd is the brightest option. HLMP-3351 provides 5.4mcd (67.5% of original), while HLMP-3351-D0000 and HLMP-3351-D0002 provide 2.1mcd (26.25% of original). Selection depends on application brightness requirements. Lower intensity variants are suitable for standard indication applications; higher intensity is required for visibility in bright ambient conditions.

Q: What packaging differences exist between HLMP-3351 variants?

A: HLMP-3351 and HLMP-3351-D0000 are supplied in Bulk packaging. HLMP-3351-D0002 is supplied in Cut Tape (CT) format. Bulk packaging is suitable for manual assembly and small-volume production. Cut Tape packaging is optimized for automated pick-and-place assembly equipment.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The MV57154 and all three HLMP-3351 variants are ROHS3 compliant. The HLMP-3351 series additionally carries REACH Unaffected status, providing enhanced environmental compliance documentation.

Q: What is the wavelength difference between MV57154 (630nm peak) and HLMP-3351 series (635nm peak)?

A: The 5nm difference falls within the red spectrum range and is not visually distinguishable in standard indication applications. Both components are specified with dominant wavelengths in the 626-630nm range, confirming red color output. Spectral matching is not a limiting factor for substitution in general indication use.

Q: Can HLMP-3351 variants be used interchangeably?

A: HLMP-3351, HLMP-3351-D0000, and HLMP-3351-D0002 are electrically and mechanically identical except for luminous intensity (HLMP-3351 at 5.4mcd vs D0000/D0002 at 2.1mcd) and packaging format (Bulk vs Cut Tape). Selection between variants depends on brightness requirements and assembly process compatibility, not on functional substitution capability.

Q: What is the current inventory status for substitutes?

A: HLMP-3351-D0000 has the highest availability at 19,677 pieces. HLMP-3351-D0002 has 10,091 pieces. HLMP-3351 base part has 5,267 pieces. All variants maintain Active product status with no discontinuation indicators.
