MV57642 Equivalent & Substitute Parts

Part Overview

The MV57642 is a red diffused LED indicator manufactured by Everlight Electronics Co Ltd, designed for through-hole mounting applications. This T-1 (3mm) form factor LED operates at 2V forward voltage with a 4mcd brightness rating and 635nm peak wavelength. The component is actively produced and RoHS3 compliant, making it suitable for modern electronic assemblies requiring red indication functionality.

Substitute parts are necessary when the primary MV57642 becomes unavailable due to supply constraints, manufacturing discontinuation, or when alternative sourcing provides equivalent performance within specified electrical and mechanical parameters.

Engineering Selection Recommendations

Parametric Equivalent (Direct Replacement):

The HLMP1302 manufactured by onsemi matches all primary electrical and mechanical parameters of the MV57642. However, the HLMP1302 carries an Obsolete product status, indicating discontinued production. This part should be selected only when existing inventory is available and long-term supply is not required. The HLMP1302 is suitable for legacy system maintenance or short-production-run applications.

Active Production Alternatives:

For applications requiring active production status and continuous supply availability, the following parts provide functional compatibility with parameter deviations:

SLR-343VR3F (Rohm Semiconductor) operates at identical 2V forward voltage and 10mA test current as the MV57642. The 16mcd brightness rating exceeds the MV57642 by 4x, and the 40° viewing angle is narrower than the 90° specification. This part is suitable for applications where increased brightness is acceptable and the narrower viewing angle does not compromise system requirements.

SSL-LX30FT4ID (Lumex Opto/Components Inc.) maintains 2V forward voltage and 635nm peak wavelength matching the MV57642. The 15mcd brightness and 100° viewing angle provide enhanced visibility characteristics. The test current specification of 20mA requires circuit design consideration but remains within standard LED driver capabilities.

HLMP-1301 and HLMP-1301-E0002 (Broadcom Limited) operate at 1.9V forward voltage with reduced brightness (3.4mcd) and narrower 60° viewing angle. These parts are suitable for applications where lower power consumption is prioritized and the reduced brightness is acceptable. The HLMP-1301-E0002 variant provides identical electrical performance in Cut Tape packaging for automated assembly processes.

LTL-1CHE (Lite-On Inc.) operates at 2V forward voltage with significantly higher brightness (12.6mcd) and 20mA test current. This part is suitable for applications requiring enhanced visibility with circuit design modifications to accommodate the higher current specification.

All recommended alternatives carry RoHS3 compliance and MSL 1 (Unlimited) ratings, ensuring regulatory alignment and storage compatibility with the MV57642.

Frequently Asked Questions (FAQ)

Q: Can HLMP1302 be used as a direct replacement for MV57642?

A: The HLMP1302 is a parametric equivalent with identical electrical specifications (2V, 10mA, 4mcd, 90° viewing angle, 635nm wavelength) and mechanical dimensions (6.30mm height, T-1 3mm form factor). However, HLMP1302 is obsolete and no longer in production. Use only if existing inventory is available and supply continuity is not required.

Q: What is the difference between SLR-343VR3F and MV57642?

A: Both parts operate at 2V forward voltage with 10mA test current and diffused lens transparency. The SLR-343VR3F provides 16mcd brightness compared to MV57642's 4mcd, and features a 40° viewing angle versus the MV57642's 90°. The SLR-343VR3F is suitable when increased brightness is acceptable and the narrower viewing angle does not impact application requirements.

Q: Why do some substitute parts have different test current specifications?

A: Test current specifications (10mA vs. 20mA) reflect the manufacturer's standard operating conditions for brightness measurement. Parts with 20mA test current (LTL-1CHE, SSL-LX30FT4ID, Rohm SLI and SLI-343 series) can operate at lower currents but are characterized at higher test points. Circuit design must accommodate the specified test current for accurate brightness performance.

Q: Is HLMP-1301 compatible with MV57642 in all applications?

A: HLMP-1301 operates at 1.9V forward voltage (0.1V lower than MV57642) with 3.4mcd brightness (15% lower) and 60° viewing angle (30° narrower). Compatibility depends on application tolerance for reduced brightness and narrower viewing angle. The lower forward voltage may provide marginal power savings in current-limited circuits.

Q: What packaging options are available for substitute parts?

A: MV57642 is supplied in Bulk packaging. Substitute parts are available in Bulk (standard), Cut Tape (CT) for automated assembly, and other packaging formats. HLMP-1301-E0002 is available in Cut Tape packaging for high-volume automated production. Packaging selection depends on assembly process requirements.

Q: Are all substitute parts RoHS3 compliant?

A: All recommended active production substitute parts carry RoHS3 compliance certification. HLMP1302 (obsolete) does not specify RoHS status in available documentation. Verify RoHS compliance with the supplier for applications requiring regulatory certification.

Q: Can SSL-LX30FT4ID replace MV57642 in brightness-critical applications?

A: SSL-LX30FT4ID provides 15mcd brightness compared to MV57642's 4mcd, representing a 3.75x increase. The 100° viewing angle exceeds MV57642's 90°. This part is suitable for applications where enhanced brightness improves visibility. Circuit design must accommodate the 20mA test current specification.

Q: What is the height difference between MV57642 and substitute parts?

A: MV57642 maximum height is 6.30mm. Substitute parts range from 5.20mm (LTL-1CHE) to 6.70mm (SSL-LX30FT4ID). Height variations within ±0.5mm are mechanically compatible with standard through-hole PCB layouts. Verify clearance for applications with height-constrained mounting areas.

Q: Do all substitute parts use the same radial package configuration?

A: All substitute parts listed use radial package configuration with through-hole mounting, matching the MV57642 form factor. This ensures mechanical compatibility with existing PCB designs without layout modifications.
