Substitute Part Grouping Explanation

Substitution for the MV57622 is determined by strict alignment of the following electrical and mechanical parameters:

Color & Wavelength: Red color with peak wavelength in the 620–635nm range
Lens Configuration: 3mm T-1 through-hole radial package with round domed top lens
Electrical Characteristics: Forward voltage (Vf) between 1.9V–2V; test current 10mA–20mA
Optical Output: Millicandela rating and viewing angle compatibility
Lens Transparency: Clear or diffused lens options
Mounting & Physical: Through-hole radial mounting; height compatibility within 5.60mm–6.35mm range
Compliance & Status: RoHS3 compliance and active product status preferred for new designs

Substitute parts are grouped into two categories: direct electrical equivalents (matching 2V forward voltage and 10mA test current) and parametric alternatives (1.9V forward voltage with 20mA test current, offering higher luminous intensity).

Engineering Selection Recommendations

Primary Substitutes (Active Status, RoHS3 Compliant):

HLMP-1321 and HLMP-1321-G0002 (Broadcom Limited) are the preferred direct substitutes. Both maintain the 3mm T-1 clear lens configuration, 45° viewing angle, and 10mA test current. Forward voltage is 1.9V (0.1V lower than MV57622), and luminous intensity is 30mcd (2.5× higher). These parts are active products with ROHS3 compliance and unlimited MSL rating. HLMP-1321-G0002 offers superior inventory availability (6053 pcs) in Cut Tape packaging.

Secondary Substitutes (Active Status, Higher Luminous Intensity):

SLI-343URCT32 (Rohm Semiconductor) is active and RoHS3 compliant, featuring 450mcd luminous intensity with clear lens transparency. This part operates at 1.9V forward voltage with 20mA test current and 3.10mm lens diameter. Height is 5.60mm, within acceptable mechanical tolerance. Viewing angle is 40° (5° narrower than MV57622).

Alternative Substitutes (Not For New Designs):

SLI-343UR3F and SLI-343URC3F (Rohm Semiconductor) are classified as "Not For New Designs" and feature diffused lens transparency with significantly higher luminous intensity (350mcd and 450mcd respectively). These parts are suitable only for replacement applications where existing designs accommodate diffused lens characteristics.

Parametric Equivalent (Obsolete Status):

HLMP1320 (onsemi) is an obsolete parametric equivalent matching the MV57622 electrical specifications (2V forward voltage, 10mA test current, 12mcd luminous intensity). This part does not provide a path forward for new production.

Compatibility Considerations:

All substitute parts maintain through-hole radial mounting and 3mm T-1 package form factor. Forward voltage variance (1.9V vs. 2V) requires circuit verification for current-limiting resistor recalculation. Luminous intensity increases in active substitutes may require optical design review for applications with strict brightness specifications. Lens transparency differences (clear vs. diffused) affect light distribution patterns and must be evaluated against application requirements.

Frequently Asked Questions (FAQ)

Q: Can HLMP-1321 directly replace MV57622 without circuit modification?

A: HLMP-1321 is electrically compatible with MV57622 in most applications. The 0.1V forward voltage difference (1.9V vs. 2V) is within typical circuit tolerance for indicator applications. However, current-limiting resistor values should be recalculated if precise current control is required. The 30mcd luminous intensity (vs. 12mcd) is higher but acceptable for standard indication purposes.

Q: What is the difference between HLMP-1321 and HLMP-1321-G0002?

A: Both parts are electrically and optically identical. The primary difference is packaging: HLMP-1321 is supplied in Bulk packaging, while HLMP-1321-G0002 is supplied in Cut Tape (CT) format. HLMP-1321-G0002 offers higher inventory availability (6053 pcs vs. 2400 pcs) and is suitable for automated assembly processes.

Q: Why do SLI-343 series parts have higher millicandela ratings?

A: SLI-343 series parts operate at 20mA test current (vs. 10mA for MV57622), resulting in higher luminous intensity output. SLI-343UR3F delivers 350mcd and SLI-343URC3F delivers 450mcd at this elevated current level. These parts are suitable for applications requiring higher brightness but require circuit redesign to accommodate the increased current draw.

Q: Are diffused lens alternatives suitable for direct replacement?

A: SLI-343UR3F and SLI-343URC3F feature diffused lens transparency, which scatters light over a wider area compared to the clear lens of MV57622. These parts are suitable only if the application design accommodates diffused light distribution. Optical performance and viewing characteristics will differ significantly.

Q: What is the significance of "Not For New Designs" status?

A: Parts marked "Not For New Designs" (SLI-343UR3F and SLI-343URC3F) are available for replacement and maintenance of existing products but should not be selected for new product development. These parts may have limited long-term availability or planned discontinuation. For new designs, select HLMP-1321, HLMP-1321-G0002, or SLI-343URCT32.

Q: How do viewing angle differences affect substitution?

A: MV57622 has a 45° viewing angle, while SLI-343 series parts have 40° viewing angles. A narrower viewing angle concentrates light output in a smaller cone, potentially affecting visibility in applications requiring wide-angle indication. Circuit board layout and optical design should be reviewed if substituting with narrower viewing angle parts.

Q: Is ROHS3 compliance required for my application?

A: ROHS3 compliance is mandatory for products sold in the European Union and many other markets. HLMP-1321, HLMP-1321-G0002, SLI-343URCT32, and TLHR4205 are all ROHS3 compliant. MV57622 and HLMP1320 do not specify RoHS status and may not meet regulatory requirements for new production.

Q: What packaging options are available for high-volume production?

A: HLMP-1321-G0002 is supplied in Cut Tape (CT) format with 6053 pcs inventory, optimized for automated pick-and-place assembly. SLI-343URCT32 is supplied in Tape & Box (TB) format with 870 pcs inventory. Bulk packaging is available for HLMP-1321 and SLI-343UR3F/URC3F but is less suitable for automated assembly processes.
