SMLE12BC7TT86FN Equivalent & Substitute Parts

Part Overview

The SMLE12BC7TT86FN is a blue LED indication component manufactured by Rohm Semiconductor, designed for surface mount applications in the 0603 (1608 Metric) package format. This discrete LED operates at a forward voltage of 2.9V with a test current of 5mA and provides 22 millicandela of light output through a clear, rectangular flat-top lens.

The SMLE12BC7TT86FN is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for applications utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SMLE12BC7TT86FN is determined by strict alignment of the following electrical and mechanical parameters:

Electrical Parameters:

• Forward voltage (Vf): 2.9V typical
• Test current: 5mA
• Color: Blue spectrum

Mechanical Parameters:

• Package format: 0603 (1608 Metric)
• Mounting type: Surface Mount
• Physical dimensions: 1.60mm L x 0.80mm W
• Maximum height: 0.40mm
• Lens style: Rectangle with Flat Top
• Lens size: 1.20mm x 0.80mm

Compliance Parameters:

• RoHS3 compliance
• Manufacturer: Rohm Semiconductor

The SMLEN3BC8TT86 meets all substitution criteria. While the millicandela rating differs (40mcd versus 22mcd), this represents an increase in light output intensity and does not prevent functional substitution in applications where the original component is specified.

Parameter Comparison

Engineering Selection Recommendations

The SMLEN3BC8TT86 is an active production substitute for the obsolete SMLE12BC7TT86FN. Both components are manufactured by Rohm Semiconductor and maintain identical electrical operating parameters (2.9V forward voltage, 5mA test current) and mechanical form factors (0603 package, 1.60mm x 0.80mm dimensions, 0.40mm maximum height).

Both parts carry ROHS3 compliance certification and share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications, ensuring regulatory and trade compliance equivalence.

The SMLEN3BC8TT86 provides increased luminous intensity (40mcd versus 22mcd), which represents a functional enhancement. The substitute part is currently in active production with substantial inventory availability (12,878 pieces), whereas the original part is obsolete with limited remaining stock (1,104 pieces).

Selection of the SMLEN3BC8TT86 is appropriate for new designs and production continuity where the SMLE12BC7TT86FN is no longer available.

Frequently Asked Questions (FAQ)

Q: Can the SMLEN3BC8TT86 be used as a direct replacement for the SMLE12BC7TT86FN?

A: Yes. Both components share identical electrical parameters (2.9V forward voltage, 5mA test current), mechanical dimensions (1.60mm x 0.80mm, 0.40mm height), package format (0603/1608 Metric), and mounting type (Surface Mount). The substitute part is manufactured by the same supplier (Rohm Semiconductor) and maintains equivalent compliance certifications.

Q: What is the difference in light output between these two parts?

A: The SMLEN3BC8TT86 produces 40 millicandela compared to 22 millicandela for the SMLE12BC7TT86FN. This represents an 82% increase in luminous intensity. Both parts emit blue light in the 468-470nm wavelength range.

Q: Are there any package or footprint differences?

A: No. Both components use the 0603 (1608 Metric) package format with identical physical dimensions of 1.60mm length by 0.80mm width and a maximum height of 0.40mm. PCB footprints are interchangeable.

Q: What is the availability status of each part?

A: The SMLE12BC7TT86FN is classified as obsolete with 1,104 pieces in remaining stock. The SMLEN3BC8TT86 is in active production status with 12,878 pieces currently available.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the SMLE12BC7TT86FN and SMLEN3BC8TT86 are ROHS3 compliant and carry identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications.

Q: Can the increased brightness of the substitute part cause design issues?

A: The increased luminous intensity of the SMLEN3BC8TT86 (40mcd versus 22mcd) is a functional enhancement. Applications designed for the original 22mcd component will operate with increased light output. Circuit-level current limiting and forward voltage characteristics remain identical, requiring no design modifications.
