Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SML012ECTT86 is determined by the following critical parameters:

Mechanical Compatibility: Package type (1208/3020 Metric), physical dimensions (3.00mm L x 2.00mm W, 1.50mm max height), and surface mount mounting type must remain identical to ensure PCB layout compatibility without redesign.

Electrical Compatibility: Color (green), lens transparency (clear), millicandela rating (360mcd), forward voltage (3.3V nominal), and test current (20mA) establish functional equivalence for indication circuits.

Regulatory Compliance: RoHS3 compliance and MSL rating (3, 168 Hours) must be maintained for manufacturing and storage requirements.

The SML012ENTT86 qualifies as a substitute based on these parameters, with the primary distinction being packaging format (Cut Tape versus Tape & Reel) and active product status.

Parameter Comparison

Engineering Selection Recommendations

The SML012ENTT86 is the qualified substitute for the obsolete SML012ECTT86. Both parts maintain identical mechanical compatibility, electrical performance within acceptable tolerances, and regulatory compliance status. The SML012ENTT86 offers the advantage of active product status, ensuring continued availability and supply chain reliability.

The forward voltage differential (3.3V versus 3.2V) is within typical LED tolerance ranges and does not require circuit redesign for standard indication applications. Both parts meet ROHS3 compliance and identical MSL requirements, supporting equivalent manufacturing and storage protocols.

The primary consideration is packaging format: the substitute is supplied in Tape & Reel format rather than Cut Tape, which may affect procurement and assembly processes depending on production volume and equipment capabilities.

Frequently Asked Questions (FAQ)

Q: Can the SML012ENTT86 be used as a direct replacement for the SML012ECTT86?

A: Yes. Both parts share identical package dimensions (1208/3020 Metric), physical size (3.00mm L x 2.00mm W, 1.50mm height), and electrical specifications (360mcd, 20mA test current, green clear lens). The forward voltage difference (3.2V versus 3.3V) is within acceptable operating range for indication circuits.

Q: What is the difference between Cut Tape and Tape & Reel packaging?

A: Cut Tape (CT) packaging provides individual strips of components, suitable for lower-volume or manual assembly operations. Tape & Reel (TR) packaging supplies components on continuous reels, optimized for high-speed automated assembly equipment. Both formats contain identical components; the difference is in delivery and handling method.

Q: Why is the SML012ECTT86 listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The SML012ENTT86 remains in active production and serves as the current equivalent for new designs and replacement applications.

Q: Are there any compliance differences between these parts?

A: No. Both parts maintain identical RoHS3 compliance and MSL rating (3, 168 Hours), supporting equivalent manufacturing, storage, and handling requirements.

Q: What wavelength should I use for circuit design calculations?

A: The SML012ECTT86 specifies 518nm peak wavelength. The SML012ENTT86 specifies 525nm dominant wavelength. Both values fall within the standard green LED spectrum and do not affect functional performance in indication applications.
