Substitute Part Grouping Explanation

Substitute parts for the MV3750A3R0 are classified into two categories based on electrical and mechanical compatibility:

Parametric Equivalents share all critical electrical and mechanical parameters with the main part:

Voltage - Forward (Vf): 2.2V
Current - Test: 20mA
Millicandela Rating: 150mcd
Lens Transparency: Clear
Lens Size: 5mm, T-1 3/4
Mounting Type: Through Hole
Wavelength - Peak: 635nm
Package / Case: Radial

Similar Parts maintain the same form factor, mounting type, and general optical characteristics but differ in one or more electrical parameters (forward voltage, test current, or brightness rating). These parts are suitable only when circuit design accommodates the parameter differences.

The following parts meet parametric equivalence criteria: HLMP3750A (onsemi), MV3750 (onsemi), and MV3750B4R0 (Fairchild Semiconductor).

The following parts are classified as similar: 4302H1-12V and 4302H1-5V (Visual Communications Company - VCC), and HLMP-C223 (Broadcom Limited).

Engineering Selection Recommendations

For Direct Replacement (Parametric Equivalents):

MV3750B4R0 (Fairchild Semiconductor) is the primary parametric equivalent. It maintains identical electrical specifications (2.2V forward voltage, 20mA test current, 150mcd brightness), identical lens transparency (clear), identical viewing angle (24°), and identical maximum height (8.89mm). The part is in active product status with 7850 units in stock. RoHS3 compliance is not applicable per vendor specification; REACH status is vendor undefined.

MV3750 (onsemi) is a parametric equivalent with identical electrical and optical specifications and matching maximum height (8.89mm). However, this part is obsolete and should be selected only when MV3750B4R0 is unavailable.

HLMP3750A (onsemi) is a parametric equivalent with identical electrical and optical specifications but differs in maximum height (12.19mm versus 8.89mm). This part is obsolete and should be selected only when space constraints do not apply and other options are unavailable.

For Functional Alternatives (Similar Parts):

HLMP-C223 (Broadcom Limited) maintains clear lens transparency and similar viewing angle (25° versus 24°), with higher brightness (170mcd versus 150mcd) and slightly lower forward voltage (1.9V versus 2.2V). This part is in active status with 19025 units in stock and is ROHS3 compliant. Selection requires circuit verification to confirm compatibility with 1.9V forward voltage and higher brightness output.

4302H1-5V and 4302H1-12V (Visual Communications Company - VCC) feature diffused lens transparency, significantly lower brightness (8mcd versus 150mcd), and higher viewing angles (60° versus 24°). These parts are suitable only for applications where diffused appearance, lower brightness, and wider viewing angle are acceptable design parameters.

Frequently Asked Questions (FAQ)

Q: Can HLMP3750A be used as a direct replacement for MV3750A3R0?

A: HLMP3750A is a parametric equivalent with identical electrical specifications (2.2V, 20mA, 150mcd) and lens characteristics. However, the maximum height is 12.19mm compared to 8.89mm for the MV3750A3R0. Verify that the additional 3.3mm height does not conflict with PCB layout or enclosure constraints before selection.

Q: What is the difference between parametric equivalents and similar parts?

A: Parametric equivalents share all critical electrical and mechanical specifications with the main part, including forward voltage, test current, brightness rating, lens transparency, and viewing angle. Similar parts maintain the same form factor and mounting type but differ in one or more electrical parameters. Similar parts require circuit design verification before use.

Q: Is HLMP-C223 compatible with MV3750A3R0 circuits?

A: HLMP-C223 differs in forward voltage (1.9V versus 2.2V) and brightness (170mcd versus 150mcd). The lower forward voltage may affect current-limiting resistor calculations in the circuit. The higher brightness output may be visible in the application. Circuit verification is required to confirm compatibility.

Q: Why are 4302H1-5V and 4302H1-12V listed as similar rather than equivalent?

A: These parts differ significantly in forward voltage (5V and 12V versus 2.2V), test current (10mA and 13mA versus 20mA), brightness (8mcd versus 150mcd), lens transparency (diffused versus clear), and viewing angle (60° versus 24°). These differences make them suitable only for applications with different electrical and optical requirements.

Q: What is the inventory status for each substitute part?

A: MV3750B4R0 has 7850 units in stock. HLMP-C223 has the highest inventory at 19025 units. MV3750 (onsemi) has 752 units. HLMP3750A has 891 units. 4302H1-5V has 2640 units. 4302H1-12V has 1927 units.

Q: Are all substitute parts RoHS3 compliant?

A: MV3750A3R0, MV3750B4R0, 4302H1-5V, 4302H1-12V, and HLMP-C223 are ROHS3 compliant. HLMP3750A and MV3750 (onsemi) have REACH status listed as unaffected. MV3750B4R0 has RoHS status listed as not applicable.

Q: What is the moisture sensitivity level for these parts?

A: All listed parts have Moisture Sensitivity Level (MSL) of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
