• Mounting Type: Surface Mount
• Color: Orange (605nm wavelength range)
• Voltage - Forward (Vf): Within acceptable operating range for 2.05V nominal specification
• Current - Test: 20mA standard test condition
• RoHS Status: ROHS3 Compliant

Identified Substitute Parts:

1. SML-H12D8TT86 (Rohm Semiconductor) – Direct orange LED substitute with active product status
2. 150080YS75000 (Würth Elektronik) – Yellow LED substitute with different wavelength specification

Parameter Comparison

Engineering Selection Recommendations

SML-H12D8TT86 (Rohm Semiconductor): This substitute maintains identical color (orange) and wavelength (605nm) specification as the SML-212DTT86. Forward voltage differs by 0.15V (2.2V vs 2.05V), which remains within typical LED circuit design tolerances. The SML-H12D8TT86 carries Active product status and improved moisture sensitivity rating (MSL 3 vs MSL 4), providing superior long-term reliability for new production support. Both parts are ROHS3 compliant and share identical package geometry.

150080YS75000 (Würth Elektronik): This substitute differs in color specification (yellow vs orange) and wavelength (590nm vs 605nm). Forward voltage is 2V, which is lower than the original specification. The millicandela rating is significantly higher at 120mcd compared to 63mcd. This part is suitable only for applications where yellow indication is functionally equivalent to orange, or where increased brightness is beneficial. ROHS3 compliance and improved MSL rating (3 vs 4) are present.

Frequently Asked Questions (FAQ)

Q: Can SML-H12D8TT86 be used as a direct replacement for SML-212DTT86?

A: Yes. Both parts are orange 605nm LEDs in 0805 surface mount package with identical millicandela rating (63mcd) and test current (20mA). The forward voltage difference of 0.15V (2.2V vs 2.05V) is within standard LED circuit design margins. The SML-H12D8TT86 has active product status and superior moisture sensitivity characteristics.

Q: Is 150080YS75000 compatible with SML-212DTT86?

A: Compatibility depends on application requirements. The 150080YS75000 is a yellow LED (590nm) versus orange (605nm), resulting in visually different indication color. The higher brightness (120mcd vs 63mcd) and lower forward voltage (2V vs 2.05V) may require circuit verification. Use this substitute only when yellow indication is functionally acceptable.

Q: What is the impact of the forward voltage difference between SML-212DTT86 (2.05V) and SML-H12D8TT86 (2.2V)?

A: The 0.15V difference is typical within LED indicator circuit design. Standard current-limiting resistor calculations accommodate this variance. No circuit redesign is required for most applications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. SML-212DTT86, SML-H12D8TT86, and 150080YS75000 are all ROHS3 compliant.

Q: What is the significance of the Moisture Sensitivity Level (MSL) difference?

A: SML-212DTT86 has MSL 4 (72-hour floor life), while both substitutes have MSL 3 (168-hour floor life). Lower MSL ratings provide extended handling time before reflow soldering, reducing moisture-related defects during assembly.

Q: Do all parts use identical 0805 package dimensions?

A: Yes. All three parts use 0805 (2012 Metric) surface mount package with 2.00mm length and 1.25mm width. Height specifications are 0.90mm (SML-212DTT86 and SML-H12D8TT86) and 0.80mm (150080YS75000), which is negligible for PCB layout purposes.
