MV8732 LED Orange Clear T-1 3/4 Through Hole Equivalent & Substitute Parts

Part Overview

The MV8732 is an orange 615nm LED indication component manufactured by onsemi, designed for through-hole mounting applications. This discrete radial LED operates at 2.1V forward voltage with a 20mA test current and delivers 940mcd brightness at a 20° viewing angle. The product is currently obsolete, making equivalent and substitute parts necessary for ongoing production, maintenance, and design updates. Suitable alternatives must maintain compatibility with through-hole mounting, similar electrical characteristics, and comparable optical performance within acceptable tolerances.

Engineering Selection Recommendations

For Direct Orange LED Replacement (Preferred):

Select from Broadcom Limited HLMP-EJ series (HLMP-EJ08-WZ000, HLMP-EJ24-QT000, HLMP-EJ30-NR000, or HLMP-EJ30-NR0DD) when color matching is required. All are ROHS3 Compliant and Active products with established supply chains. HLMP-EJ30-NR0DD offers the highest inventory (19,741 pcs) and Cut Tape packaging for automated assembly. Forward voltage (1.98V) is within acceptable tolerance of MV8732 (2.1V). Brightness varies by model; select based on application requirements:

HLMP-EJ08-WZ000: 10,750mcd, 8° viewing angle (narrow beam)
HLMP-EJ24-QT000: 2,175mcd, 23° viewing angle (moderate beam)
HLMP-EJ30-NR000/NR0DD: 1,290mcd, 30° viewing angle (wide beam, closest to MV8732 brightness profile)

SLI-560DT3F (Rohm Semiconductor) is not recommended for new designs despite orange color compatibility, as its product status is "Not For New Designs."

For Alternative Yellow LED Substitution:

When color change is acceptable, yellow LED alternatives provide active product status and robust supply availability. SLI-570Y2T3F (Rohm Semiconductor) matches MV8732 electrical characteristics most closely: 2.1V forward voltage, 20° viewing angle, and 5,200mcd brightness. LTL2R3KSK (Lite-On Inc.) offers 1,150mcd at 30° viewing angle with 2.05V forward voltage. OVLFY3C7 (TT Electronics/Optek Technology) provides 7,400mcd at 30° viewing angle with 2V forward voltage and highest inventory (41,918 pcs).

All recommended substitutes maintain through-hole radial mounting, 5mm T-1 3/4 form factor, clear lens transparency, and MSL 1 (Unlimited) rating. Verify circuit design tolerance for forward voltage variation (1.9V to 2.2V range) and brightness differences before final selection.

Frequently Asked Questions (FAQ)

Q: Can MV8732 be replaced with a yellow LED substitute?

A: Yes, if the application permits color change. Yellow LED substitutes (5219466F, OVLFY3C7, OVLGY0C9B9, LTL2R3KSK, SLI-570Y2T3F) maintain identical through-hole mounting, 5mm T-1 3/4 form factor, and compatible electrical specifications (forward voltage 2.0V to 2.2V, 20mA test current). Verify that the circuit design and end-user requirements accept yellow indication instead of orange.

Q: What is the acceptable forward voltage range for MV8732 substitutes?

A: The MV8732 operates at 2.1V typical forward voltage. Acceptable substitutes range from 1.9V to 2.2V, as this tolerance accommodates manufacturing variation and circuit design margins. Verify your circuit's current-limiting resistor design accommodates this range without exceeding maximum LED current (typically 30mA absolute maximum for T-1 3/4 LEDs).

Q: Are all substitute parts RoHS compliant?

A: All recommended substitute parts are ROHS3 Compliant or REACH Unaffected. The MV8732 is REACH Unaffected. Verify compliance requirements for your specific application and region before final selection.

Q: What is the difference between HLMP-EJ30-NR000 and HLMP-EJ30-NR0DD?

A: Both parts are electrically and optically identical (1,290mcd, 30° viewing angle, 1.98V forward voltage, 605nm dominant wavelength). The primary difference is packaging: HLMP-EJ30-NR000 is supplied in Bulk packaging, while HLMP-EJ30-NR0DD is supplied in Cut Tape (CT) packaging suitable for automated pick-and-place assembly. HLMP-EJ30-NR0DD has significantly higher inventory (19,741 pcs vs. 926 pcs).

Q: How does brightness (mcd) affect substitution suitability?

A: Brightness is application-dependent. The MV8732 delivers 940mcd at 20° viewing angle. Orange substitutes range from 1,000mcd to 10,750mcd depending on model. Select based on your circuit's intended brightness requirement: lower mcd values (1,000–1,290mcd) are suitable for indicator applications with moderate visibility; higher mcd values (2,175–10,750mcd) are suitable for high-visibility or long-distance indication. Verify that your circuit's current-limiting resistor accommodates the selected brightness without exceeding maximum ratings.

Q: Can I use OVLGY0C9B9 as a substitute despite its 8° narrow viewing angle?

A: OVLGY0C9B9 is electrically compatible but differs significantly in optical characteristics: 14,000mcd brightness at 8° viewing angle versus MV8732's 940mcd at 20° viewing angle. Use only if your application requires narrow-beam, high-intensity yellow indication. For general indicator applications requiring wide viewing angle, select OVLFY3C7 (30° viewing angle, 7,400mcd) or LTL2R3KSK (30° viewing angle, 1,150mcd) instead.

Q: What mounting considerations apply to through-hole substitutes?

A: All substitute parts maintain radial through-hole mounting with 5mm T-1 3/4 form factor and heights within 7.70mm to 8.91mm. Verify PCB hole spacing and lead diameter compatibility with your existing design. The MV8732 height is 8.89mm; most substitutes are within ±0.2mm of this dimension, ensuring mechanical compatibility with standard through-hole footprints.
