MV53154 Yellow LED T-1 3/4 Through Hole Equivalent & Substitute Parts

Part Overview

The Everlight Electronics MV53154 is a yellow diffused LED indicator in T-1 3/4 (5mm) through-hole package, rated at 2.1V forward voltage with 8mcd luminous intensity. This component is discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives from active manufacturers. Substitute parts must maintain compatibility with existing circuit designs while meeting the same electrical and mechanical specifications for direct board-level replacement.

Engineering Selection Recommendations

Primary Substitute (Closest Match):

HLMP-3451 or HLMP-3451-D0000 (Broadcom Limited) are the preferred substitutes for MV53154. Both parts maintain identical mechanical dimensions (5mm T-1 3/4, 6.35mm height), forward voltage within acceptable tolerance (2V vs. 2.1V), test current (10mA), and viewing angle (50°). The 3.6mcd brightness is lower than the original 8mcd specification; this substitution is valid only when circuit design does not depend on the higher luminous intensity. HLMP-3451-D0000 offers superior availability (35,845 pcs in stock vs. 20,818 pcs for HLMP-3451) and is supplied in Cut Tape packaging, suitable for automated assembly.

Secondary Substitute (Voltage Compatible, Height Variation):

HLMP-3401 or HLMP-3401-E0002 (Broadcom Limited) are compatible substitutes with forward voltage of 2V and test current of 10mA. These parts feature increased height (9.19mm vs. 6.35mm) and wider viewing angle (60° vs. 50°). Substitution is valid when PCB clearance permits the additional 2.84mm height. HLMP-3401-E0002 provides the highest inventory availability (35,845 pcs) among all active substitutes.

Voltage-Specific Alternatives:

HLMP-3650 (5V forward voltage): Use only in circuits designed for 5V LED operation
HLMP-3651 (12V forward voltage): Use only in circuits designed for 12V LED operation
HLMP-4719 or HLMP-4719-A0002 (1.8V forward voltage): Use only in low-voltage applications with 1.8V supply

Non-Recommended Substitutes:

5219673F (Dialight) has reduced lens size (4.75mm vs. 5mm) and increased test current (20mA vs. 10mA), creating potential mechanical fit and circuit compatibility issues. This part is not recommended for direct replacement.

Compliance Verification:

All substitute parts listed maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, matching the original MV53154 specifications. No additional environmental or regulatory considerations apply to substitution.

Frequently Asked Questions (FAQ)

Q: Can HLMP-3451 directly replace MV53154 in all applications?

A: HLMP-3451 is mechanically and electrically compatible with MV53154 for through-hole PCB mounting. The primary difference is reduced brightness (3.6mcd vs. 8mcd). Direct replacement is valid only when the circuit design does not require the higher luminous intensity of the original part. Verify brightness requirements in the application schematic before substitution.

Q: What is the difference between HLMP-3401 and HLMP-3451?

A: Both are Broadcom yellow diffused T-1 3/4 LEDs with 2V forward voltage and 10mA test current. HLMP-3451 has lower brightness (3.6mcd) and shorter height (6.35mm), matching the MV53154 profile more closely. HLMP-3401 has higher brightness (5.7mcd) and greater height (9.19mm). Select based on PCB clearance and brightness requirements.

Q: Why does HLMP-3401-E0002 have higher inventory than HLMP-3401?

A: HLMP-3401-E0002 is supplied in Cut Tape (CT) packaging format, which is standard for automated pick-and-place assembly. HLMP-3401 is supplied in Bulk packaging. Both parts are electrically and mechanically identical; packaging format determines inventory levels and suitability for manufacturing process.

Q: Can I use HLMP-3650 or HLMP-3651 as substitutes?

A: HLMP-3650 (5V) and HLMP-3651 (12V) are not direct substitutes for MV53154 (2.1V). These parts require different circuit designs and power supply voltages. Use these parts only when the application circuit is specifically designed for 5V or 12V LED operation.

Q: What is the impact of the 2.84mm height difference between HLMP-3451 and HLMP-3401?

A: HLMP-3451 maintains the original 6.35mm height of MV53154, ensuring compatibility with existing PCB layouts and component clearances. HLMP-3401 is 9.19mm tall, requiring verification of available vertical clearance above the PCB. If clearance is limited, HLMP-3451 is the preferred choice.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed (HLMP-3401, HLMP-3451, HLMP-3650, HLMP-3651, HLMP-4719, and 5219673F) maintain ROHS3 compliance and MSL 1 moisture sensitivity rating, matching the original MV53154 specifications.

Q: What viewing angle should I select?

A: MV53154 has a 50° viewing angle. HLMP-3451 and HLMP-4719 maintain this specification. HLMP-3401, HLMP-3650, and HLMP-3651 have wider 60° viewing angles. Select based on application requirements; wider angles provide better visibility from off-axis positions but may reduce peak brightness in the forward direction.

Q: Is 5219673F (Dialight) a suitable substitute?

A: 5219673F is not recommended as a direct substitute. The lens size is reduced (4.75mm vs. 5mm), and test current is doubled (20mA vs. 10mA), creating potential mechanical fit issues and requiring circuit redesign. Broadcom HLMP series parts are preferred alternatives.
