MV53622 Yellow LED T-1 Equivalent & Substitute Parts

Part Overview

The MV53622 is a yellow LED indication component manufactured by onsemi, featuring a 3mm T-1 through-hole radial package with clear lens. This part operates at 2.1V forward voltage with 8mcd brightness rating and 45° viewing angle. The MV53622 is classified as obsolete, making equivalent substitute parts necessary for ongoing production and maintenance applications requiring yellow LED indication in T-1 form factor.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MV53622 are evaluated based on the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

• Color: Yellow
• Lens Transparency: Clear
• Lens Size: 3mm, T-1 form factor
• Mounting Type: Through Hole (Radial package)
• Wavelength range: 585nm to 590nm (yellow spectrum)

Secondary Compatibility Criteria:

• Forward voltage (Vf): 1.9V to 2.4V range acceptable for most applications
• Millicandela rating: 8mcd minimum for indication purposes
• Viewing angle: 40° to 45° acceptable
• Current rating: 10mA to 20mA test current

Substitute parts are grouped into two categories: direct replacements with similar electrical characteristics (HLMP-1421 series from Broadcom) and functional equivalents with higher brightness ratings (SLI-343 series from Rohm Semiconductor, TLHY4205 from Vishay).

Parameter Comparison

Engineering Selection Recommendations

Recommended Primary Substitutes (Active Status, Direct Compatibility):

HLMP-1421 and HLMP-1421-F0002 from Broadcom Limited are the closest functional equivalents to the MV53622. Both parts maintain yellow color, clear lens, 3mm T-1 form factor, and 45° viewing angle. Forward voltage is 2.0V (0.1V lower than MV53622), and brightness is 15mcd (higher than original 8mcd). Both are ROHS3 compliant and REACH unaffected. The primary difference is packaging: HLMP-1421 is supplied in bulk, while HLMP-1421-F0002 is supplied in Tape & Reel format for automated assembly.

Secondary Substitutes (Active Status, Higher Brightness):

TLHY4205 from Vishay Semiconductor Opto Division is an active yellow LED with 20mcd brightness, 2.4V forward voltage, and 588nm wavelength. This part maintains T-1 form factor and clear lens but operates at slightly higher voltage and provides increased brightness for applications requiring enhanced visibility.

SLI-343Y8C3F from Rohm Semiconductor (EXCELED™ series) offers significantly higher brightness at 680mcd with 2.2V forward voltage and 590nm wavelength. This part is active and ROHS3 compliant but features a narrower 40° viewing angle and slightly shorter 5.60mm height. This option is suitable for applications where increased brightness is beneficial.

Not Recommended for New Designs:

SLI-343YC3F and SLI-343YCT32 carry "Not For New Designs" status despite active availability. While functionally compatible, these parts should not be selected for new product development.

Frequently Asked Questions (FAQ)

Q: Can HLMP-1421 directly replace MV53622 in existing circuits?

A: Yes. HLMP-1421 maintains identical form factor (3mm T-1 through-hole radial), color (yellow), lens transparency (clear), and viewing angle (45°). Forward voltage is 2.0V versus 2.1V for MV53622, a 0.1V difference that is within typical circuit tolerance. The higher brightness (15mcd vs 8mcd) will not cause compatibility issues in indication applications.

Q: What is the difference between HLMP-1421 and HLMP-1421-F0002?

A: Both parts are electrically and mechanically identical. The difference is packaging only. HLMP-1421 is supplied in bulk packaging, while HLMP-1421-F0002 is supplied in Tape & Reel format. Selection depends on assembly method: bulk for manual assembly, Tape & Reel for automated pick-and-place equipment.

Q: Why do SLI-343 series parts have different heights (5.60mm vs 6.30mm)?

A: The SLI-343 series from Rohm Semiconductor uses a different mechanical design than the MV53622 and HLMP-1421 series. The 5.60mm height is within acceptable tolerance for most through-hole applications but should be verified against PCB layout constraints if height clearance is critical.

Q: Can I use SLI-343Y8C3F instead of MV53622 if brightness is not a concern?

A: SLI-343Y8C3F is functionally compatible but introduces design changes: narrower 40° viewing angle (vs 45°), higher forward voltage (2.2V vs 2.1V), and different height (5.60mm vs 6.30mm). These differences are acceptable for indication applications where brightness is not critical, but circuit design should be verified for voltage compatibility.

Q: Are all substitute parts RoHS compliant?

A: HLMP-1421, HLMP-1421-F0002, TLHY4205, and all SLI-343 variants listed are ROHS3 compliant. The original MV53622 product status is obsolete and does not carry RoHS certification information.

Q: Which substitute offers the best balance of compatibility and availability?

A: HLMP-1421 (bulk) or HLMP-1421-F0002 (Tape & Reel) from Broadcom Limited provide the closest electrical and mechanical match to MV53622 with active product status and high inventory availability (11,600 and 674 units respectively). These parts require minimal circuit redesign.
