MV8140 LED Red Clear T-1 3/4 Through Hole - Equivalent & Substitute Parts

Part Overview

The onsemi MV8140 is a red LED indication component in T-1 3/4 (5mm) through-hole package, rated at 220mcd with 1.7V forward voltage and 20mA test current. This part is classified as obsolete, making equivalent substitute parts necessary for ongoing design requirements and production continuity. Substitute parts must maintain compatibility across mechanical form factor, electrical characteristics, and mounting specifications to ensure direct replacement capability.

Substitute Part Grouping Explanation

Substitution eligibility for the MV8140 is determined by the following critical parameters:

Mechanical Compatibility: Package type must be T-1 3/4 (5mm) radial through-hole with round domed lens configuration to ensure PCB footprint and mounting compatibility.

Electrical Compatibility: Forward voltage (Vf) range of 1.7V to 2.2V and test current of 20mA define the operational envelope. Millicandela ratings between 220mcd and 1200mcd are acceptable for indication applications where brightness variation does not compromise circuit function.

Optical Characteristics: Peak wavelength in the 623nm to 660nm range (red spectrum) and viewing angles from 22° to 130° maintain the red indication function across different application geometries.

Regulatory & Compliance: All substitute parts must maintain MSL 1 (Unlimited) rating, REACH compliance status, and EAR99 export classification to match the original part's regulatory profile.

Product Status Consideration: Active status parts are preferred for long-term availability, though the original MV8140 is obsolete.

Engineering Selection Recommendations

Primary Substitutes (Closest Electrical Match):

HLMP-D105 and HLMP-D105-M0002 (Broadcom Limited) provide the closest forward voltage alignment at 1.8V with 240mcd brightness and 645nm peak wavelength. Both parts are active status with ROHS3 compliance. The M0002 variant offers tape and reel packaging for automated assembly environments.

SSL-LX5093SRC/F (Lumex Opto/Components Inc.) matches the original 1.7V forward voltage exactly and maintains 660nm peak wavelength with superior 1200mcd brightness. Active status and ROHS3 compliance ensure long-term availability and regulatory alignment.

Secondary Substitutes (Acceptable Electrical Range):

LTL2R3KEK and LTL2R3KRK (Lite-On Inc.) operate at 2V forward voltage with 700mcd and 680mcd ratings respectively, within the acceptable substitution envelope. Both maintain 30° viewing angle and compact 8.70mm height. ROHS3 compliance confirmed; REACH status affected for LTL2R3KRK.

LTL2P3KRK (Lite-On Inc.) delivers 800mcd at 2V with 631nm wavelength and 22° viewing angle. Compact 8.70mm height and active status support production continuity.

OVLLR8C7 (TT Electronics/Optek Technology) provides 900mcd at 2V with 623nm wavelength and exceptional 100° viewing angle. Compact 6.80mm height and high inventory availability (90,624 pcs) support volume requirements.

Marginal Substitutes (Electrical Deviation):

XLM2ACR169W (SunLED) operates at 2.2V forward voltage with 695mcd and 130° viewing angle. Height of 4.85mm is significantly reduced compared to MV8140. Suitable only where forward voltage tolerance and compact form factor are acceptable.

5219184F (Dialight) and HLMP-D155-F0002 (Broadcom Limited) exhibit significant brightness deviation (3mcd and 10mcd respectively) and are not recommended for direct replacement in standard indication circuits.

Frequently Asked Questions (FAQ)

Q: Can HLMP-D105 directly replace MV8140 in existing PCB designs?

A: Yes. HLMP-D105 maintains T-1 3/4 radial through-hole package compatibility, operates within acceptable forward voltage range (1.8V vs. 1.7V), and delivers comparable brightness (240mcd vs. 220mcd). Height difference of 4.64mm (12.44mm vs. 8.90mm) must be verified against PCB clearance constraints.

Q: What is the primary advantage of SSL-LX5093SRC/F over other substitutes?

A: SSL-LX5093SRC/F matches the original MV8140 forward voltage exactly at 1.7V and maintains identical 660nm peak wavelength. Superior 1200mcd brightness provides design margin for indication visibility. Compact 8.60mm height closely matches the original 8.90mm specification.

Q: Are there brightness-critical applications where substitute selection matters?

A: Yes. Applications requiring specific brightness levels must account for millicandela variation. MV8140 at 220mcd differs significantly from high-brightness options (SSL-LX5093SRC/F at 1200mcd, OVLLR8C7 at 900mcd) and low-brightness options (5219184F at 3mcd, HLMP-D155-F0002 at 10mcd). Circuit design must accommodate brightness differences through resistor adjustment or LED current limiting modifications.

Q: What viewing angle considerations apply to substitute selection?

A: MV8140 specifies 40° viewing angle. Substitutes range from 22° (narrow, directional indication) to 130° (wide, omnidirectional indication). Narrow-angle parts (HLMP-D105 at 24°, LTL2P3KRK at 22°) concentrate light intensity; wide-angle parts (XLM2ACR169W at 130°, OVLLR8C7 at 100°) distribute light broadly. Application geometry and visibility requirements determine acceptable range.

Q: Do all substitutes maintain the same moisture sensitivity level?

A: Yes. All listed substitutes maintain MSL 1 (Unlimited) rating, matching MV8140 specifications. Storage and handling requirements remain unchanged across all substitute options.

Q: Which substitutes offer best long-term availability?

A: OVLLR8C7 (90,624 pcs inventory), LTL2R3KEK (9,468 pcs), HLMP-D105 (8,220 pcs), and LTL2R3KRK (6,132 pcs) demonstrate highest inventory levels. All are active status parts with established supply chains. SSL-LX5093SRC/F (10,715 pcs) also provides strong availability with exact electrical match to MV8140.

Q: Can forward voltage differences affect circuit operation?

A: Yes. Forward voltage differences of 0.1V to 0.5V alter LED current in constant-voltage circuits. Circuits with fixed series resistors must be recalculated. Example: 5V supply with 220Ω resistor yields 21.8mA at 1.7V (MV8140) but 15.0mA at 2.2V (XLM2ACR169W). Current-limiting designs with active regulation are less sensitive to Vf variation.
