Key Parameters

Substitute Part Grouping Explanation

Substitution of the SMLE12BC7TT86FP is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Package format: 0603 (1608 Metric)
• Mounting type: Surface Mount
• Color: Blue
• Forward voltage (Vf): 2.9V
• Test current: 5mA
• Lens style: Rectangle with Flat Top
• Lens size: 1.20mm x 0.80mm
• Physical dimensions: 1.60mm L x 0.80mm W
• Height (Max): 0.40mm
• RoHS compliance: ROHS3 Compliant

The SMLEN3BC8TT86 from Rohm Semiconductor qualifies as a substitute part based on matching all critical parameters. While the substitute part exhibits a higher millicandela rating (40mcd versus 22mcd) and different wavelength specifications, these represent performance enhancements rather than incompatibilities. The substitute maintains identical mechanical form factor, electrical operating conditions, and regulatory compliance status.

Engineering Selection Recommendations

The SMLEN3BC8TT86 is a direct substitute for the obsolete SMLE12BC7TT86FP based on the following engineering criteria:

Product Status Alignment: The substitute part is classified as Active, ensuring ongoing availability and supply chain continuity. The original part's obsolete status necessitates transition to an actively manufactured alternative.

Regulatory Compliance: Both parts maintain ROHS3 compliance and identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications, ensuring no regulatory barriers to substitution.

Mechanical and Electrical Compatibility: The substitute part maintains identical package format (0603/1608 Metric), mounting type (Surface Mount), physical dimensions (1.60mm L x 0.80mm W, 0.40mm height), forward voltage (2.9V), and test current (5mA). These parameters ensure direct compatibility with existing PCB layouts and circuit designs without modification.

Performance Enhancement: The substitute part provides increased light output (40mcd versus 22mcd), representing a performance improvement for indication applications. The wavelength specification (470nm dominant) aligns with standard blue LED applications.

Frequently Asked Questions (FAQ)

Q: Can the SMLEN3BC8TT86 be used as a direct replacement for the SMLE12BC7TT86FP without PCB modifications?

A: Yes. Both parts share identical package format (0603/1608 Metric), physical dimensions (1.60mm L x 0.80mm W, 0.40mm maximum height), mounting type (Surface Mount), and electrical operating parameters (2.9V forward voltage, 5mA test current). No PCB layout changes are required.

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

A: The SMLE12BC7TT86FP produces 22 millicandela, while the SMLEN3BC8TT86 produces 40 millicandela. The substitute part provides approximately 82% greater light intensity, which represents an enhancement for indication applications.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both parts are ROHS3 compliant and share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications. No regulatory barriers exist to substitution.

Q: What is the wavelength difference between these parts?

A: The SMLE12BC7TT86FP has a peak wavelength of 468nm. The SMLEN3BC8TT86 has a dominant wavelength of 470nm. Both wavelengths fall within the standard blue LED spectrum and are visually indistinguishable in indication applications.

Q: Is the SMLEN3BC8TT86 available in the same packaging options?

A: The SMLEN3BC8TT86 is supplied in Cut Tape (CT) and Digi-Reel® packaging formats. The original part's packaging format is not specified in available data. Verify packaging requirements against your procurement specifications.

Q: Why is the original part classified as obsolete?

A: The SMLE12BC7TT86FP is listed as obsolete by the manufacturer. The SMLEN3BC8TT86 represents the active product line continuation from Rohm Semiconductor for blue LED indication in the 0603 package format.
