Substitute Part Grouping Explanation

Substitution for the MV8342 is determined by the following critical parameters:

Primary Compatibility Criteria:

Lens size: 5mm T-1 3/4 form factor
Mounting type: Through hole radial configuration
Lens transparency: Clear
Forward voltage range: 1.98V to 2.2V (compatible with standard 20mA LED circuits)
Current rating: 20mA test current
Moisture sensitivity: MSL 1 (Unlimited)

Secondary Selection Factors:

Color: Yellow or orange wavelength (590nm–609nm range)
Viewing angle: 8° to 45° (application-dependent)
Millicandela rating: 140mcd to 18,150mcd (brightness varies by application)
Product status: Active preferred for long-term availability

The substitute parts listed below maintain mechanical and electrical compatibility within these parameters. Color variations (yellow to orange) and brightness differences reflect available alternatives within the T-1 3/4 through-hole LED category.

Engineering Selection Recommendations

Yellow LED Direct Equivalent: The 5219466F from Dialight is the closest functional equivalent to the MV8342. It maintains yellow color (583nm peak wavelength), similar forward voltage (2.2V), through-hole radial package, and T-1 3/4 form factor. The 140mcd brightness is lower than the MV8342's 370mcd, and the 24° viewing angle is narrower than 45°. This part is active and RoHS3 compliant, ensuring long-term availability and regulatory compliance.

Orange LED Alternatives: The Broadcom Limited HLMP-EJ series provides orange LED alternatives (605nm wavelength, 1.98V forward voltage) across multiple brightness and viewing angle configurations. These parts are all active, RoHS3 compliant, and available in bulk or tape & box packaging. Selection within this series depends on application-specific brightness and viewing angle requirements:

HLMP-EJ08 variants (8° viewing angle): 10,750mcd to 18,150mcd for high-brightness applications
HLMP-EJ15 variants (15° viewing angle): 1,690mcd to 3,700mcd for moderate-brightness applications
HLMP-EJ24-QT000 (23° viewing angle): 2,175mcd for wide-angle moderate-brightness applications

Packaging Considerations: Most substitutes are available in bulk packaging. Tape & box (TB) packaging is available for HLMP-EJ10-XZ0DD and HLMP-EJ15-SV0DD, suitable for automated assembly processes.

Height Variations: Standard height is 8.89mm to 8.91mm. Extended-height variants (HLMP-EJ10-XZ0DD at 12.62mm and HLMP-EJ17-SV000 at 12.67mm) are available for applications requiring increased lead length.

Frequently Asked Questions (FAQ)

Q: Can I substitute an orange LED for the yellow MV8342? A: Orange LEDs in the HLMP-EJ series are mechanically and electrically compatible with the MV8342 in terms of package, mounting, and voltage characteristics. However, color change from yellow (590nm) to orange (605–609nm) may affect visual indication in applications where color distinction is critical. Evaluate application requirements before substitution.

Q: What is the difference between the HLMP-EJ08, HLMP-EJ15, and HLMP-EJ24 series? A: These Broadcom series differ primarily in viewing angle and brightness. HLMP-EJ08 offers 8° narrow viewing angle with high brightness (10,750–18,150mcd). HLMP-EJ15 provides 15° viewing angle with moderate brightness (1,690–3,700mcd). HLMP-EJ24 delivers 23° viewing angle with 2,175mcd brightness. Select based on application visibility requirements and spatial constraints.

Q: Are all substitute parts RoHS3 compliant? A: The 5219466F is RoHS3 compliant. All Broadcom HLMP-EJ series parts are RoHS3 compliant. The original MV8342 product status is obsolete and does not carry RoHS certification. For new designs and regulated applications, active RoHS3-compliant substitutes are recommended.

Q: What is the difference between bulk and tape & box packaging? A: Bulk packaging is suitable for manual assembly and small-volume applications. Tape & box (TB) packaging is designed for automated pick-and-place assembly processes. Both packaging types contain the same electrical and mechanical components; selection depends on assembly methodology.

Q: Can I use HLMP-EJ10-XZ0DD or HLMP-EJ17-SV000 as direct replacements? A: These extended-height variants (12.62mm and 12.67mm respectively) are mechanically compatible but have longer leads than the standard 8.89mm MV8342. They are suitable for applications with increased PCB-to-component clearance requirements. Verify PCB layout compatibility before substitution.

Q: What forward voltage should I use for circuit design with these substitutes? A: The MV8342 operates at 2.1V. The 5219466F operates at 2.2V (0.1V higher). Broadcom HLMP-EJ series parts operate at 1.98V (0.12V lower). All are within standard LED circuit tolerance. Recalculate series resistor values if precise current limiting is required: R = (Vsupply − Vf) / Iled.
