Substitute Part Grouping Explanation

Substitution eligibility for the MV53154 is determined by the following critical parameters:

Primary Compatibility Criteria:

Color: Yellow
Lens Transparency: Diffused
Lens Size: 5mm, T-1 3/4
Mounting Type: Through Hole
Package / Case: Radial
Wavelength - Peak: 585nm (±5nm tolerance acceptable)

Secondary Electrical Criteria:

Voltage - Forward (Vf): 2.0V to 2.1V range
Current - Test: 10mA nominal
Millicandela Rating: 3.6mcd minimum (brightness tolerance)
Viewing Angle: 50° to 60° acceptable

Substitute parts are grouped into two categories: direct mechanical and electrical equivalents (identical form factor and voltage), and functional equivalents (same optical and electrical performance within acceptable tolerances). Parts with different forward voltages (5V, 12V, 1.8V) are listed for reference but require circuit redesign and are not direct substitutes.

Engineering Selection Recommendations

Recommended Direct Substitutes (2.0V to 2.1V Forward Voltage):

HLMP-3451 and HLMP-3451-D0000 are the closest functional equivalents to MV53154. Both parts maintain identical mechanical form factor (5mm T-1 3/4, 6.35mm height), matching 10mA test current, and 50° viewing angle. Forward voltage is 2V (0.1V lower than MV53154), which is within acceptable tolerance for standard LED indication circuits. Brightness rating of 3.6mcd is lower than the original 8mcd but remains suitable for indicator applications. Both parts are active products with ROHS3 compliance and unlimited moisture sensitivity rating.

HLMP-3401 and HLMP-3401-E0002 offer alternative compatibility with identical electrical specifications (2V, 10mA) and mechanical package (5mm T-1 3/4). These parts feature 5.7mcd brightness and 60° viewing angle, providing wider visibility. Height specification of 9.19mm exceeds the original 6.35mm, requiring PCB layout verification. HLMP-3401-E0002 is available in Cut Tape packaging with significantly higher inventory (35,845 pcs), supporting high-volume production requirements.

5219673F from Dialight maintains 2.1V forward voltage matching the original specification exactly and provides higher brightness (12.6mcd) with 60° viewing angle. Lens size of 4.75mm diameter and height of 8.21mm represent minor dimensional variations that may require mechanical clearance verification in confined spaces.

Alternative Substitutes (Different Forward Voltage):

HLMP-3650 (5V) and HLMP-3651 (12V) require circuit redesign and are not direct substitutes. These parts are listed for reference only when application voltage differs from the original 2.1V specification.

HLMP-4719 operates at 1.8V with 2mA test current, suitable only for low-power applications and requires circuit modification.

Compliance and Availability:

All recommended substitute parts are active products with ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements. Inventory availability ranges from 2,014 to 35,845 units across substitute options, supporting both prototype and production-scale deployment.

Frequently Asked Questions (FAQ)

Q: Can HLMP-3451 directly replace MV53154 without circuit modification?

A: HLMP-3451 is compatible with circuits designed for 2.0V to 2.1V forward voltage operation. The 0.1V difference from MV53154 (2.1V vs. 2.0V) is within standard LED tolerance and does not require circuit redesign. Brightness reduction from 8mcd to 3.6mcd is acceptable for indicator applications where absolute luminosity is not critical. Mechanical form factor and mounting are identical.

Q: What is the difference between HLMP-3401 and HLMP-3401-E0002?

A: Both parts are electrically and optically identical (2V, 10mA, 5.7mcd, 60° viewing angle, 5mm T-1 3/4 package). The primary difference is packaging: HLMP-3401 is supplied in Bulk, while HLMP-3401-E0002 is supplied in Cut Tape (CT). Cut Tape packaging is preferred for automated assembly processes. HLMP-3401-E0002 has significantly higher inventory availability (35,845 pcs vs. 2,300 pcs).

Q: Why is 5219673F listed as a substitute if it has different dimensions?

A: 5219673F maintains critical electrical compatibility (2.1V forward voltage, 10mA test current, yellow diffused 585nm wavelength) and mechanical mounting type (through-hole radial). Dimensional variations (4.75mm lens diameter vs. 5mm, 8.21mm height vs. 6.35mm) are minor and acceptable for most applications. Verification of PCB hole spacing and clearance is required before implementation.

Q: Can HLMP-3650 or HLMP-3651 be used as substitutes?

A: HLMP-3650 (5V) and HLMP-3651 (12V) are not direct substitutes due to different forward voltage specifications. These parts require circuit redesign including resistor value recalculation and power supply modification. Use these parts only when application voltage differs from the original 2.1V specification.

Q: What does "Obsolete" product status mean for MV53154?

A: Obsolete status indicates that onsemi has discontinued manufacturing and support for MV53154. No new inventory will be produced. Existing stock of 994 pcs is available but finite. Substitution to active products (HLMP-3451, HLMP-3401, 5219673F) is necessary for long-term supply chain continuity and ongoing production support.

Q: Are all substitute parts ROHS3 compliant?

A: All listed substitute parts carry ROHS3 compliance certification and REACH unaffected status, meeting current environmental regulations. MV53154, being an obsolete part, does not have ROHS3 certification listed but is not subject to REACH restrictions.

Q: What is the significance of the 50° vs. 60° viewing angle difference?

A: Viewing angle determines the cone of light emission. MV53154 and HLMP-3451 feature 50° viewing angle (narrower, more directional), while HLMP-3401 and 5219673F feature 60° viewing angle (wider, more dispersed). For applications requiring directional indication, 50° angle is preferred. For applications requiring broader visibility, 60° angle is advantageous. Circuit performance is not affected by this parameter.
