Substitute Part Grouping Explanation

Substitute parts are classified into two categories based on substitution compatibility with the MV8342:

Category A: Direct Yellow LED Substitutes (Highest Compatibility)

Direct substitutes maintain the yellow color specification (590-591nm peak wavelength), T-1 3/4 form factor, through-hole mounting, and forward voltage within the 2.0V to 2.1V range. These parts are electrically and mechanically interchangeable with the MV8342 in standard indication applications.

Key matching parameters:

Color: Yellow
Lens Size: 5mm, T-1 3/4
Mounting Type: Through Hole
Voltage - Forward (Vf): 2.0V to 2.1V
Current - Test: 20mA
Package / Case: Radial
RoHS Status: ROHS3 Compliant

Category B: Alternative Color LED Substitutes (Conditional Compatibility)

Alternative color substitutes (orange wavelength 605-611nm) share identical mechanical form factors and electrical test conditions but differ in color specification. These parts are suitable only when application requirements permit color variation or when orange indication is functionally equivalent to yellow in the circuit design.

Key matching parameters:

Lens Size: 5mm, T-1 3/4
Mounting Type: Through Hole
Current - Test: 20mA
Package / Case: Radial
RoHS Status: ROHS3 Compliant
Forward Voltage: 1.9V to 2.0V (lower than yellow variants)

Engineering Selection Recommendations

For Direct Replacement (Yellow LED Category A):

Parts SLI-570YT3F, LTL2R3KSK, and OVLFY3C7 are suitable direct replacements for the MV8342 based on matching color specification, form factor, and electrical operating parameters. All three maintain ROHS3 compliance and unlimited moisture sensitivity rating.

SLI-570YT3F (Rohm Semiconductor) provides the closest electrical match with identical 2.1V forward voltage and 20° viewing angle specification, supporting applications requiring consistent brightness distribution.

LTL2R3KSK (Lite-On Inc.) offers the highest inventory availability (15591 Pcs) with 2.05V forward voltage and 30° viewing angle, suitable for applications tolerating moderate brightness variation.

OVLFY3C7 (TT Electronics/Optek Technology) delivers significantly higher brightness output (7400mcd) with 2V forward voltage and 30° viewing angle, applicable to applications requiring enhanced visibility.

For Alternative Color Applications (Orange LED Category B):

Parts HLMP-EJ30-NR0DD, SLI-570DT3F, and SSL-LX5093SOC are orange LED alternatives sharing identical mechanical form factors and through-hole mounting. These components are suitable only when circuit design permits color substitution or when orange indication provides functional equivalence.

All substitute parts maintain ROHS3 compliance and MSL 1 rating consistent with the MV8342 specification.

Frequently Asked Questions (FAQ)

Q1: Can SLI-570YT3F directly replace MV8342 without circuit modification?

A: Yes. SLI-570YT3F maintains identical forward voltage (2.1V), test current (20mA), color specification (yellow, 591nm peak wavelength), and T-1 3/4 form factor. The component is mechanically and electrically interchangeable in through-hole applications.

Q2: What is the primary difference between LTL2H3KSK and LTL2R3KSK?

A: Both are Lite-On yellow LEDs with identical 2.05V forward voltage and 5mm T-1 3/4 form factor. The primary difference is viewing angle: LTL2H3KSK provides 15° narrow angle with 2500mcd brightness, while LTL2R3KSK provides 30° wider angle with 1150mcd brightness. Selection depends on application viewing geometry requirements.

Q3: Why do orange LED alternatives have lower forward voltage than yellow variants?

A: Forward voltage is determined by the semiconductor bandgap energy corresponding to the emitted wavelength. Orange LEDs (605-611nm) require lower bandgap energy than yellow LEDs (589-591nm), resulting in lower forward voltage (1.9V-2.0V versus 2.0V-2.1V). Circuit design must account for this voltage difference.

Q4: Is 5219466F (Dialight) suitable as a direct replacement?

A: 5219466F is a yellow LED with compatible color specification but presents two compatibility considerations: lens size is 4.83mm diameter (slightly smaller than MV8342's 5mm), and forward voltage is 2.2V (higher than MV8342's 2.1V). Mechanical fit and circuit current-limiting design must be verified before substitution.

Q5: What inventory considerations apply to substitute selection?

A: All listed substitutes maintain active product status with ROHS3 compliance. Inventory availability ranges from 803 Pcs (MV8342) to 79595 Pcs (OVLGY0C9B9). High-inventory alternatives such as OVLFY3C7 (41918 Pcs) and OVLGY0C9B9 (79595 Pcs) provide supply chain continuity advantages for volume applications.

Q6: Can OVLGY0C9B9 replace MV8342 in applications requiring wide viewing angle?

A: OVLGY0C9B9 is a yellow LED with 2V forward voltage and 5mm T-1 3/4 form factor, but features an 8° narrow viewing angle compared to MV8342's 45° wide angle. This part is unsuitable for applications requiring the MV8342's wide viewing angle specification. OVLFY3C7 with 30° viewing angle is a more appropriate alternative for moderate angle requirements.

Q7: What compliance certifications apply to all listed parts?

A: All parts listed maintain ROHS3 compliance and MSL 1 (unlimited moisture sensitivity) rating. Orange LED alternatives (HLMP-EJ30-NR0DD, SLI-570DT3F, SSL-LX5093SOC) and yellow alternatives (LTL2H3KSK, LTL2R3KSK) carry REACH status designations as specified in the component data. ECCN and HTSUS classifications are identical across all parts (EAR99 and 8541.41.0000 respectively).
