Substitute Part Grouping Explanation

Substitution eligibility for the SML-210MTT86 is determined by the following critical parameters:

Primary Compatibility Criteria:

Package / Case: 0805 (2012 Metric) — physical footprint must match for PCB compatibility
Mounting Type: Surface Mount — assembly process compatibility
Color: Green — functional requirement for indication
Voltage - Forward (Vf): 2.0V to 2.2V range — circuit design tolerance
Current - Test: 20mA — standard test condition
Lens Transparency: Clear — optical performance class
RoHS Status: ROHS3 Compliant — regulatory requirement

Secondary Consideration Parameters:

Millicandela Rating: 4mcd to 25mcd — acceptable brightness variation for indication applications
Wavelength - Peak: 560nm to 572nm — green spectrum range
Height (Max): 0.80mm to 0.90mm — PCB assembly clearance

Parts meeting all primary criteria are classified as direct substitutes. Parts with variations in secondary parameters require application-specific evaluation but remain mechanically and electrically compatible within the 0805 package class.

Engineering Selection Recommendations

Direct Substitutes (Rohm Semiconductor EXCELED™ Series):

SML-H12P8TT86 and SML-H12M8TT86 are manufactured by the same supplier (Rohm Semiconductor) and share identical package, voltage, and current specifications. Both parts are in Active product status, ensuring long-term availability. SML-H12M8TT86 provides brightness closest to the original at 25mcd versus 16mcd. Both comply with ROHS3 and maintain MSL 3 rating.

Compatible Alternatives (Würth Elektronik WL-SMCW Series):

150080VS75000 matches the 0805 package, forward voltage (2V), and wavelength (570nm/572nm) within acceptable tolerance. This part operates at 40mcd brightness with 140° viewing angle. Height is reduced to 0.80mm, suitable for space-constrained applications. Active product status ensures supply continuity.

Compatible Alternatives (VCC CMD Series):

CMD17-21VGC/TR8 maintains 0805 package compatibility with 2.1V forward voltage and 570nm wavelength. Brightness at 10mcd is lower than the original. MSL rating improves to 2 (1 Year), providing superior moisture protection. Height increases to 1.20mm; verify PCB clearance requirements.

Color Variant (Everlight Electronics):

17-21SYGC/S530-E3/TR8 is a green-yellow LED with 573nm/575nm wavelength, differing from pure green. This part is suitable only for applications where green-yellow indication is acceptable. Brightness at 31mcd exceeds the original. Height at 1.10mm requires clearance verification.

All substitute parts listed maintain ROHS3 compliance and are suitable for applications requiring green LED indication in 0805 surface mount packages at 20mA test current.

Frequently Asked Questions (FAQ)

Q: Can I use SML-H12P8TT86 as a direct replacement for SML-210MTT86?

A: Yes. Both parts share identical package (0805), forward voltage (2.2V), current rating (20mA), and RoHS compliance. The primary difference is brightness: SML-H12P8TT86 operates at 4mcd versus 16mcd. Verify that reduced brightness is acceptable for your indication application.

Q: What is the key difference between SML-H12M8TT86 and SML-H12P8TT86?

A: Both are Rohm EXCELED™ series parts in 0805 package with 2.2V forward voltage. SML-H12M8TT86 provides 25mcd brightness (closer to the original 16mcd), while SML-H12P8TT86 provides 4mcd. Peak wavelength differs: SML-H12M8TT86 at 572nm versus SML-H12P8TT86 at 560nm.

Q: Why does 150080VS75000 have a lower forward voltage (2V vs 2.2V)?

A: Forward voltage variation within 0.2V is acceptable for LED indication circuits. The 150080VS75000 operates at 2V typical, which is within standard tolerance for green LEDs. Verify your circuit design accommodates this voltage range.

Q: Can I use 17-21SYGC/S530-E3/TR8 if my application requires pure green indication?

A: No. This part is a green-yellow LED with 573nm wavelength. Use only if your application accepts green-yellow color. For pure green indication, select SML-H12M8TT86, SML-H12P8TT86, 150080VS75000, or CMD17-21VGC/TR8.

Q: What does MSL 2 (1 Year) on CMD17-21VGC/TR8 mean compared to MSL 3 (168 Hours)?

A: MSL 2 indicates superior moisture resistance with 1-year shelf life at 30°C/85% RH. MSL 3 allows 168 hours (7 days) at the same conditions. CMD17-21VGC/TR8 is preferable for long-term storage or humid environments.

Q: Are all substitute parts available in the same packaging format as SML-210MTT86?

A: SML-210MTT86 is supplied in Cut Tape (CT) & Digi-Reel®. Substitute parts vary: SML-H12P8TT86 and SML-H12M8TT86 are Tape & Reel (TR); 150080VS75000 and PG1112H-TR are Cut Tape (CT) & Digi-Reel®; CMD17-21VGC/TR8 is Tape & Reel (TR); 17-21SYGC/S530-E3/TR8 packaging not specified. Confirm packaging availability with your supplier.

Q: What is the maximum height consideration for PCB assembly?

A: SML-210MTT86 maximum height is 0.90mm. Substitute parts range from 0.80mm (150080VS75000) to 1.20mm (CMD17-21VGC/TR8). Verify PCB clearance requirements, particularly for conformal coating or secondary assembly operations.

Q: Why is SML-210MTT86 marked as Last Time Buy?

A: Last Time Buy status indicates Rohm Semiconductor has discontinued this product. Existing inventory is available but no future production is planned. Transition to an active substitute part to ensure long-term supply security.
