SML-A12UTT86 Equivalent & Substitute Parts

Part Overview

The SML-A12UTT86 is a red surface-mount LED indicator manufactured by Rohm Semiconductor, part of the EXCELED™ series. This component is a 2-SMD, no-lead package with a dominant wavelength of 624nm and a forward voltage of 2V at 20mA test current. The part is currently classified as "Not For New Designs," which necessitates identification of active equivalent alternatives for ongoing production and new design implementations. The SML-A12UTT86J serves as the direct parametric equivalent with active product status.

Substitute Part Grouping Explanation

Substitution eligibility for the SML-A12UTT86 is determined by strict equivalence across the following critical parameters:

• Wavelength - Dominant: 624nm (red spectrum)
• Voltage - Forward (Vf) (Typ): 2V
• Current - Test: 20mA
• Millicandela Rating: 100mcd
• Lens Style: Rectangle with Flat Top
• Lens Size: 1.20mm x 0.55mm
• Mounting Type: Surface Mount, Right Angle
• Package / Case: 2-SMD, No Lead
• Supplier Device Package: 1611(0605)
• Size / Dimension: 1.60mm L x 1.15mm W
• Height (Max): 0.65mm
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 3 (168 Hours)

The SML-A12UTT86J maintains identical electrical and mechanical specifications across all parameters listed above, qualifying it as a direct parametric equivalent. The primary distinction is product status: SML-A12UTT86 is designated "Not For New Designs," while SML-A12UTT86J carries "Active" status.

Engineering Selection Recommendations

For new design implementations, the SML-A12UTT86J is the appropriate selection. This part maintains full parametric equivalence with the SML-A12UTT86 while carrying active product status from Rohm Semiconductor. Both parts satisfy ROHS3 compliance and REACH unaffected requirements, ensuring regulatory alignment for current manufacturing standards.

For existing designs currently utilizing the SML-A12UTT86, direct substitution with the SML-A12UTT86J is permissible without circuit modification, as all electrical characteristics, mechanical dimensions, and environmental specifications remain identical. The MSL rating of 3 (168 Hours) applies to both parts, requiring equivalent moisture control during storage and assembly.

Frequently Asked Questions (FAQ)

Q: Can the SML-A12UTT86J be used as a direct replacement for the SML-A12UTT86 in existing assemblies?

A: Yes. All electrical parameters (forward voltage, test current, wavelength), mechanical dimensions (1.60mm L x 1.15mm W, 0.65mm height), and package specifications (2-SMD, no lead, 1611(0605)) are identical. No circuit redesign is required.

Q: What is the significance of the "Not For New Designs" designation on the SML-A12UTT86?

A: This designation indicates that Rohm Semiconductor recommends against using this part number for new product development. The SML-A12UTT86J, with identical specifications and active status, is the recommended alternative for new designs.

Q: Are there any differences in compliance or environmental specifications between these parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry an MSL rating of 3 (168 Hours). Compliance and environmental handling requirements are identical.

Q: What are the critical parameters that define substitution eligibility for this LED?

A: Substitution is determined by equivalence in wavelength (624nm), forward voltage (2V), test current (20mA), luminous intensity (100mcd), lens geometry (rectangle with flat top, 1.20mm x 0.55mm), mounting type (surface mount, right angle), and package configuration (2-SMD, no lead, 1611(0605)).

Q: Is the SML-A12UTT86J available in the same packaging format?

A: Yes. The SML-A12UTT86J is supplied in Tape & Reel (TR) packaging, identical to the SML-A12UTT86.
