Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SML-210PTT86 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Package / Case: 0805 (2012 Metric) — all substitutes must match this footprint
• Mounting Type: Surface Mount — all substitutes must be surface mount
• Lens Transparency: Clear — all substitutes must have clear lens
• Voltage - Forward (Vf): 2.0V to 2.2V range — acceptable tolerance for circuit compatibility
• Current - Test: 20mA — standard test current for green LEDs
• RoHS Status: ROHS3 Compliant — regulatory requirement maintained

Secondary Consideration Parameters:

• Color: Green or green-spectrum variants (green-yellow, yellow-green) acceptable for indication applications
• Wavelength - Dominant: 555nm to 575nm range — visible green spectrum
• Millicandela Rating: 4mcd to 450mcd — brightness variation acceptable depending on application requirements
• Lens Style: Rectangle with Flat Top — consistent across all candidates
• Lens Size: 1.30mm to 1.52mm width variation — within mechanical tolerance

The five substitute parts listed below meet the primary compatibility criteria and maintain regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

SML-H12P8TT86 (Rohm Semiconductor EXCELED™ Series)

This part is the manufacturer-recommended substitute. It maintains identical forward voltage (2.2V), test current (20mA), package dimensions, and height specifications. The wavelength shift from 555nm to 560nm remains within the green spectrum perception range. Product status is Active with full availability. This option provides the highest compatibility with minimal circuit redesign requirements.

150080VS75000 (Würth Elektronik WL-SMCW Series)

This part operates at 2V forward voltage with 40mcd brightness. The wavelength-dominant specification of 570nm places it in the yellow-green boundary. Height is reduced to 0.80mm. Product status is Active. Circuit design must accommodate the 0.2V lower forward voltage. This option is suitable for applications where brightness increase and lower voltage operation are acceptable.

150080GS75000 (Würth Elektronik WL-SMCW Series)

This part operates at 3.2V forward voltage with significantly higher brightness (450mcd) and 520nm wavelength. Height is reduced to 0.80mm. Product status is Active. The 1V forward voltage increase requires circuit redesign and is suitable only for applications where higher brightness is required and circuit voltage tolerance permits the change.

17-21SYGC/S530-E3/TR8 (Everlight Electronics)

This part is classified as green-yellow with 573nm wavelength and 31mcd brightness at 2V forward voltage. Height is increased to 1.10mm. Product status is Active with high inventory availability. The color shift toward yellow and increased height may impact visual indication consistency and PCB clearance. Suitable for applications where color variation is acceptable.

QBLP631-AG (QT Brightek QBLP631 Series)

This part is classified as yellow-green with 570nm wavelength and 50mcd brightness at 2V forward voltage. Height is reduced to 0.80mm. Product status is Active with highest inventory availability. The color classification shift and brightness increase require application-level assessment. Suitable for applications where brightness enhancement and color tolerance are acceptable.

Frequently Asked Questions (FAQ)

Q: Can SML-H12P8TT86 be used as a direct replacement for SML-210PTT86?

A: Yes. Both parts share identical forward voltage (2.2V), test current (20mA), package (0805), dimensions (2.00mm L x 1.25mm W), and height (0.90mm). The wavelength shift from 555nm to 560nm is within acceptable green spectrum variation for indication applications. Both are ROHS3 compliant with MSL 3 rating.

Q: What is the impact of forward voltage differences in substitute selection?

A: Forward voltage determines the voltage drop across the LED in circuit operation. The SML-210PTT86 operates at 2.2V. Substitutes at 2V require 0.2V less voltage drop, affecting current-limiting resistor calculations. Substitutes at 3.2V require 1V more voltage drop, necessitating circuit redesign. Voltage compatibility must be verified against the application's power supply and resistor network.

Q: Are the Würth Elektronik parts (150080GS75000, 150080VS75000) compatible with the original circuit?

A: Both Würth parts maintain the 0805 package and surface mount configuration. However, 150080GS75000 operates at 3.2V (1V higher than original), requiring circuit modification. 150080VS75000 operates at 2V (0.2V lower), requiring resistor recalculation. Both have reduced height (0.80mm vs 0.90mm), which may affect PCB clearance. Electrical compatibility must be assessed per application requirements.

Q: What is the significance of millicandela rating differences?

A: Millicandela (mcd) rating indicates LED brightness. The SML-210PTT86 provides 4mcd. Substitutes range from 31mcd to 450mcd. Higher brightness may cause visual perception changes in indication applications. Lower brightness may reduce visibility. Selection depends on application requirements for indicator brightness and power consumption constraints.

Q: Can green-yellow or yellow-green LEDs replace the pure green SML-210PTT86?

A: Color substitution depends on application requirements. The 17-21SYGC/S530-E3/TR8 (green-yellow, 573nm) and QBLP631-AG (yellow-green, 570nm) shift the perceived color toward yellow. For applications where color consistency is critical (status indication, safety signaling), these substitutes may not be acceptable. For general indication purposes where color tolerance exists, these parts are mechanically and electrically compatible.

Q: What packaging format differences exist among the substitutes?

A: The SML-210PTT86 is supplied in Tape & Reel (TR) format. Würth Elektronik parts are supplied in Cut Tape (CT) & Digi-Reel® format. Everlight and QT Brightek parts use standard Tape & Reel or equivalent formats. Packaging format affects procurement and assembly processes but does not impact electrical or mechanical compatibility. Verify packaging availability with supplier for production requirements.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance status, matching the original SML-210PTT86 specification. All parts also maintain MSL 3 (168 Hours) moisture sensitivity level, ensuring consistent handling and storage requirements.
