MV3750P LED Red Clear T-1 3/4 Through Hole Equivalent & Substitute Parts

Part Overview

The MV3750P is a red LED indication component manufactured by Everlight Electronics Co Ltd, designed for through-hole mounting applications. This discrete 2.2V radial LED features a 5mm T-1 3/4 clear lens with 150mcd brightness rating and 24° viewing angle, operating at 20mA test current with a peak wavelength of 635nm. The component is currently in active product status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Equivalent and substitute parts are necessary when the primary component becomes unavailable, when alternative manufacturers are required for supply chain diversification, or when design specifications permit operation with components having similar electrical and mechanical characteristics within defined parameter tolerances.

Substitute Part Grouping Explanation

Substitute parts for the MV3750P are classified into two categories based on electrical and mechanical parameter alignment:

Parametric Equivalents maintain all critical electrical and mechanical specifications within the defined operating parameters:

Forward voltage (Vf): 2.2V
Test current: 20mA
Millicandela rating: 150mcd
Lens transparency: Clear
Lens size: 5mm T-1 3/4
Viewing angle: 24°
Peak wavelength: 635nm
Mounting type: Through hole radial
Height: 8.89mm (±tolerance)

Similar Parts share the same physical form factor (5mm T-1 3/4 through-hole radial), color (red), and wavelength family (635nm) but operate at different voltage levels or with different lens transparency characteristics. These parts require circuit design modifications to accommodate different forward voltages or test currents.

Engineering Selection Recommendations

Direct Parametric Equivalents (Recommended for Direct Substitution):

MV3750B4R0 (Fairchild Semiconductor) is the primary direct substitute, maintaining identical electrical specifications (2.2V Vf, 20mA test current, 150mcd) and mechanical dimensions (8.89mm height, 5mm T-1 3/4 clear lens). This part is currently in active product status. Note that RoHS status is listed as "Not applicable" for this component.

MV3750 (onsemi) provides parametric equivalence with matching electrical and mechanical specifications but carries obsolete product status. This part should be selected only when supply chain requirements or legacy system compatibility necessitate onsemi sourcing.

HLMP3750A (onsemi) maintains electrical equivalence but features increased height (12.19mm maximum versus 8.89mm), which may impact PCB layout compatibility in space-constrained applications. This part is obsolete.

Near-Equivalent Alternative (Conditional Substitution):

HLMP-C223 (Broadcom Limited) operates at reduced forward voltage (1.9V versus 2.2V) and delivers higher brightness (170mcd versus 150mcd) with marginally increased viewing angle (25° versus 24°). This component is active and ROHS3 compliant. Circuit design modification is required to accommodate the lower forward voltage specification.

Similar Form Factor Parts (Design Modification Required):

4302H1-5V and 4302H1-12V (Visual Communications Company - VCC) share the 5mm T-1 3/4 through-hole radial form factor and red wavelength family but feature diffused lens transparency, significantly reduced brightness (8mcd versus 150mcd), and substantially different voltage requirements (5V or 12V versus 2.2V). These components require complete circuit redesign and are suitable only for applications where brightness and viewing angle specifications differ from the MV3750P requirements.

Frequently Asked Questions (FAQ)

Q: Can HLMP-C223 be used as a direct drop-in replacement for MV3750P?

A: HLMP-C223 is not a direct drop-in replacement. While it maintains the same physical form factor (5mm T-1 3/4 through-hole radial), clear lens, and test current (20mA), the forward voltage differs (1.9V versus 2.2V). Circuit current-limiting resistor values must be recalculated to accommodate the lower forward voltage. The higher brightness (170mcd versus 150mcd) and marginally increased viewing angle (25° versus 24°) are within acceptable tolerance for most applications.

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

A: Parametric equivalents maintain all critical electrical specifications (forward voltage, test current, brightness) and mechanical dimensions (height, lens size, viewing angle) within the defined operating range. Similar parts share the same physical form factor and color but operate at different voltage levels or with different lens characteristics, requiring circuit design modifications.

Q: Why is MV3750 (onsemi) listed as obsolete when MV3750P (Everlight) is active?

A: Product status reflects the current availability and manufacturer support status. The onsemi MV3750 has been discontinued, while the Everlight MV3750P remains in active production. Obsolete parts may still be available through inventory channels but lack manufacturer support and future availability guarantees.

Q: Can 4302H1-5V replace MV3750P in a 2.2V circuit?

A: No. The 4302H1-5V operates at 5V forward voltage with 10mA test current, compared to MV3750P specifications of 2.2V and 20mA. Additionally, the diffused lens reduces brightness to 8mcd versus 150mcd, and viewing angle expands to 60° versus 24°. Complete circuit redesign is required, including new current-limiting resistor calculations and power supply modifications.

Q: Are all listed substitutes ROHS3 compliant?

A: No. MV3750B4R0 (Fairchild Semiconductor) lists RoHS status as "Not applicable." HLMP3750A and MV3750 (onsemi) list REACH status as "REACH Unaffected" rather than explicit ROHS3 compliance. For applications requiring strict ROHS3 compliance, MV3750P (Everlight), HLMP-C223 (Broadcom), 4302H1-5V, and 4302H1-12V (VCC) are confirmed compliant.

Q: What is the significance of the height difference between MV3750P (8.89mm) and HLMP3750A (12.19mm)?

A: The 3.3mm height difference may impact PCB layout in applications with vertical space constraints or specific mechanical assembly requirements. Verify clearance in the target application before substitution.

Q: Can MV3750B4R0 be used in all applications where MV3750P is specified?

A: MV3750B4R0 maintains identical electrical and mechanical specifications, making it suitable for direct substitution in most applications. However, verify that the "Not applicable" RoHS status meets your compliance requirements before final selection.
