Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SML-512DWT86 are qualified based on the following critical parameters that determine functional and mechanical compatibility:

Electrical Parameters:

• Color: Orange
• Wavelength - Dominant: 606nm (±1nm tolerance acceptable for orange LED indication)
• Millicandela Rating: 100mcd
• Current - Test: 20mA
• Mounting Type: Surface Mount

Mechanical Parameters:

• Package / Case: 0603 (1608 Metric)
• Size / Dimension: 1.60mm L x 0.80mm W
• Height (Max): 0.65mm
• Lens Color: White
• Lens Transparency: Diffused
• Lens Style: Rectangle with Flat Top

Compliance Parameters:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 3 (168 Hours)

The identified substitute parts SML-D12D1WT86 and SML-D12D8WT86 meet all critical electrical, mechanical, and compliance requirements. The forward voltage variance (2.2V vs 2V) and wavelength variance (605nm vs 606nm) fall within acceptable tolerances for orange LED indication applications and do not preclude substitution in standard circuit designs.

Parameter Comparison

Engineering Selection Recommendations

All three parts—SML-512DWT86, SML-D12D1WT86, and SML-D12D8WT86—are active production components from Rohm Semiconductor with identical ROHS3 compliance and MSL ratings. Selection between these parts is determined by packaging requirements and supply availability.

Frequently Asked Questions (FAQ)

Q: Can SML-D12D1WT86 and SML-D12D8WT86 be used interchangeably with SML-512DWT86?

A: Yes. Both substitute parts meet all critical electrical and mechanical parameters. The primary differences are forward voltage (2.2V vs 2V) and dominant wavelength (605nm vs 606nm), which are within acceptable tolerances for orange LED indication applications. Packaging format differs between the three parts.

Q: What is the difference between SML-D12D1WT86 and SML-D12D8WT86?

A: Both parts are electrically and mechanically identical with 605nm dominant wavelength and 2.2V forward voltage. The primary difference is packaging: SML-D12D1WT86 is supplied in Tape & Reel format, while SML-D12D8WT86 is supplied in Cut Tape and Digi-Reel® format. SML-D12D8WT86 is designated as EXCELED™ series.

Q: Does the 0.2V forward voltage difference between SML-512DWT86 (2V) and the substitute parts (2.2V) affect circuit design?

A: The forward voltage difference must be evaluated within the context of the specific circuit design. In standard LED indication circuits with current-limiting resistors, a 0.2V variance typically does not impact functionality. Circuit designers should verify that the higher forward voltage of the substitute parts remains within the operating parameters of the driving circuit.

Q: Are all three parts RoHS compliant?

A: Yes. SML-512DWT86, SML-D12D1WT86, and SML-D12D8WT86 are all ROHS3 compliant with REACH unaffected status.

Q: What is the Moisture Sensitivity Level (MSL) for these parts?

A: All three parts have MSL 3 rating with 168 hours maximum floor life. Standard moisture control procedures for MSL 3 components must be followed during storage and assembly.

Q: Which packaging format should I select?

A: SML-512DWT86 and SML-D12D1WT86 are supplied in Tape & Reel format, suitable for automated pick-and-place assembly. SML-D12D8WT86 is supplied in Cut Tape and Digi-Reel® format. Selection depends on assembly equipment compatibility and supply chain requirements.
