Key Parameters

Substitute Part Grouping Explanation

Substitution of the SML-210LTT86 is determined by strict alignment of the following critical parameters:

• Package / Case: 0805 (2012 Metric) surface mount package
• Mounting Type: Surface Mount
• Color: Red
• Lens Style: Rectangle with Flat Top
• Lens Transparency: Clear
• Size / Dimension: 2.00mm L x 1.25mm W
• Height (Max): 0.90mm
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 3 (168 Hours)

The SML-H12V8TT86 qualifies as a substitute part because it maintains identical mechanical compatibility (package, size, height, lens configuration) and regulatory compliance (RoHS3, MSL-3). Electrical parameters including forward voltage, test current, millicandela rating, and wavelength may vary within acceptable ranges for red LED indication applications, provided the substitute part operates within the same functional category and mounting footprint.

Parameter Comparison

Engineering Selection Recommendations

The SML-H12V8TT86 is the qualified substitute for the SML-210LTT86 based on the following engineering criteria:

Mechanical Compatibility: Both parts share identical package dimensions (0805 / 2012 Metric), footprint (2.00mm L x 1.25mm W), and maximum height (0.90mm). PCB layout and assembly processes require no modification.

Regulatory Compliance: Both parts maintain ROHS3 compliance and identical Moisture Sensitivity Level (MSL-3, 168 Hours), ensuring equivalent handling, storage, and reflow requirements.

Product Status Advantage: The SML-H12V8TT86 carries Active product status, providing assured long-term availability and supply chain stability compared to the Not For New Designs status of the SML-210LTT86.

Electrical Parameter Differences: The SML-H12V8TT86 operates at a higher forward voltage (2.2V versus 1.75V) and delivers increased brightness (25mcd versus 10mcd). These differences must be evaluated within the context of the specific application circuit. The wavelength shift from 660nm (peak) to 630nm (dominant) represents a minor color shift within the red spectrum and is acceptable for standard indication applications.

Frequently Asked Questions (FAQ)

Q: Can the SML-H12V8TT86 be used as a direct drop-in replacement for the SML-210LTT86?

A: Yes, from a mechanical and regulatory standpoint. Both parts use the identical 0805 (2012 Metric) package with matching footprint dimensions and height. PCB layout modifications are not required. However, the higher forward voltage (2.2V versus 1.75V) and increased brightness (25mcd versus 10mcd) require circuit validation to ensure the application can accommodate these electrical differences.

Q: What are the key differences between these two parts?

A: The primary differences are forward voltage (1.75V versus 2.2V), brightness rating (10mcd versus 25mcd), and wavelength specification (660nm peak versus 630nm dominant). Both parts maintain identical package geometry, RoHS compliance, and MSL rating. The SML-H12V8TT86 is an active product, while the SML-210LTT86 is not recommended for new designs.

Q: Are there any packaging differences between these parts?

A: Yes. The SML-210LTT86 is supplied in Cut Tape (CT) & Digi-Reel® packaging, while the SML-H12V8TT86 is supplied in Tape & Reel (TR) packaging. Both formats are standard for surface mount components and are compatible with automated assembly equipment.

Q: Will the wavelength difference (660nm versus 630nm) affect my application?

A: The wavelength difference represents a minor shift within the red spectrum. For standard indication applications, this difference is typically imperceptible to the human eye. Applications requiring precise color matching or spectral filtering should evaluate the specific wavelength requirements of the end application.

Q: What is the significance of the Product Status difference?

A: The SML-210LTT86 is classified as Not For New Designs, indicating Rohm Semiconductor has discontinued active development. The SML-H12V8TT86 carries Active status, ensuring continued availability, manufacturing support, and supply chain reliability for future production runs.
