Engineering Selection Recommendations

All substitute parts listed maintain identical mechanical compatibility with the SML-011UTT86 through matching package specifications, mounting type, and physical dimensions. All parts are Active status products from Rohm Semiconductor and carry ROHS3 compliance certification.

SML-012V8TT86: Red 630nm LED with 2.2V forward voltage and 63mcd rating. Maintains equivalent brightness to the main part with a 10nm wavelength shift. Moisture sensitivity improved to MSL 2.

SML-012VTT86A: Red 630nm LED with 2V forward voltage and 71mcd rating. Matches the original forward voltage specification with 8mcd higher brightness output. Moisture sensitivity improved to MSL 2.

SML-012D8TT86: Orange 605nm LED with 2.2V forward voltage and 160mcd rating. Represents a different color specification with significantly higher brightness. Moisture sensitivity improved to MSL 2.

Selection depends on specific wavelength and brightness requirements of the application circuit.

Frequently Asked Questions (FAQ)

Q: Can SML-012V8TT86 directly replace SML-011UTT86?

A: Mechanical and electrical compatibility is maintained. The 10nm wavelength difference (630nm vs 620nm) and 0.2V forward voltage increase must be evaluated against circuit design specifications.

Q: What is the difference between SML-012VTT86A and SML-012V8TT86?

A: Both are red 630nm LEDs in the same package. SML-012VTT86A operates at 2V forward voltage with 71mcd brightness, while SML-012V8TT86 operates at 2.2V with 63mcd brightness. Forward voltage selection depends on circuit power supply design.

Q: Is SML-012D8TT86 compatible with SML-011UTT86 applications?

A: Mechanical and electrical compatibility exists. The orange 605nm wavelength and 160mcd brightness represent significant functional differences requiring application-level verification.

Q: Do all substitute parts share the same package dimensions?

A: Yes. All listed parts use the 1208 (3020 metric) package with identical 3.00mm L x 2.00mm W dimensions and 1.50mm maximum height.

Q: What is the moisture sensitivity difference between the main part and substitutes?

A: SML-011UTT86 carries MSL 4 (72 hours), while all substitute parts carry MSL 2 (1 year), indicating improved moisture resistance in substitute options.

Q: Are all parts ROHS3 compliant?

A: Yes. The main part and all substitute parts are ROHS3 compliant and carry Active product status from Rohm Semiconductor.
