Engineering Selection Recommendations

Direct Substitutes (Recommended for Replacement):

HLMP-1401 and HLMP-1401-E0000 (Broadcom Limited) are active products with ROHS3 compliance and identical T-1 form factor. Both operate at 2.0V forward voltage with 10mA test current, matching the MV53642 electrical operating point. HLMP-1401-E0000 provides 5.7mcd brightness, closest to the original 4.5mcd specification. Viewing angle is reduced to 60° compared to the original 90°, requiring circuit-level verification for application fit.

LTL-4251 (Lite-On Inc.) is an active product with ROHS3 compliance and exact 2.1V forward voltage match. Brightness is elevated to 8.7mcd with narrower 40° viewing angle. This part is listed in the MV53642 substitute field, indicating manufacturer-recognized compatibility. REACH Affected status requires supply chain verification for regulated substance compliance.

SLR-332YY3F (Rohm Semiconductor) operates at 2.1V with 10mA test current and 6.3mcd brightness. Viewing angle is 85°, closely matching the original 90°. Height is reduced to 4.60mm, providing improved PCB clearance. Active product status with ROHS3 compliance supports new design adoption.

Conditional Substitutes (Application-Dependent):

SLI-343Y8Y3F (Rohm Semiconductor) operates at elevated 2.2V forward voltage and 20mA test current, requiring circuit redesign for current-limiting resistor adjustment. Brightness is significantly elevated at 470mcd. Narrower 40° viewing angle and reduced 5.60mm height require mechanical verification. Active product status with ROHS3 compliance supports availability.

Obsolete/Legacy Support:

No additional obsolete-status parts are recommended for new designs. Existing inventory of MV53642 should be prioritized for legacy production runs.

Frequently Asked Questions (FAQ)

Q: Can HLMP-1401 directly replace MV53642 without circuit modification?

A: HLMP-1401 operates at 2.0V forward voltage versus MV53642 at 2.1V. Current-limiting resistor values may require adjustment depending on circuit design. Verify brightness output (2.2mcd vs. 4.5mcd) meets application requirements. Viewing angle is reduced from 90° to 60°, which may affect visibility in wide-angle applications.

Q: What is the difference between HLMP-1401 and HLMP-1401-E0000?

A: Both are Broadcom Limited yellow diffused T-1 LEDs with identical electrical specifications (2.0V, 10mA). The primary difference is brightness: HLMP-1401-E0000 provides 5.7mcd compared to HLMP-1401 at 2.2mcd. Selection depends on required brightness level for the application.

Q: Is LTL-4251 a direct substitute?

A: LTL-4251 matches the MV53642 forward voltage (2.1V) and test current (10mA) exactly. Brightness is higher at 8.7mcd, and viewing angle is narrower at 40°. It is listed in the MV53642 substitute field by onsemi, confirming compatibility. REACH Affected status requires verification of supply chain compliance documentation.

Q: Why does SLI-343Y8Y3F require circuit modification?

A: SLI-343Y8Y3F operates at 2.2V forward voltage and 20mA test current, compared to MV53642 at 2.1V and 10mA. The higher test current requires recalculation of the current-limiting resistor to prevent LED damage. Brightness is significantly elevated at 470mcd, which may exceed application requirements.

Q: Can I use SLR-332YY3F in a space-constrained PCB layout?

A: Yes. SLR-332YY3F has a maximum height of 4.60mm, compared to MV53642 at 6.30mm, providing 1.70mm additional clearance. Electrical specifications match closely (2.1V, 10mA, 6.3mcd). Viewing angle is 85°, nearly identical to the original 90°. Verify mechanical fit with PCB component placement constraints.

Q: What compliance certifications should I verify before substitution?

A: All recommended substitutes carry ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, matching MV53642 specifications. LTL-4251 has REACH Affected status, requiring documentation review. All parts are classified as EAR99 and HTSUS 8541.41.0000, consistent with the original part.

Q: Are there viewing angle considerations for my application?

A: Viewing angle varies across substitutes: MV53642 (90°), HLMP-1401 (60°), LTL-4251 (40°), SLI-343Y8Y3F (40°), SLR-332YY3F (85°). Narrower angles concentrate brightness in a specific direction, while wider angles distribute light across a broader field. Select based on indicator placement and visibility requirements.
