Substitute Part Grouping Explanation

Substitute parts for the SML012EC4TT86 are qualified based on the following criteria:

Mechanical Compatibility: Package type (1208/3020 Metric), physical dimensions (3.00mm L x 2.00mm W, 1.50mm max height), lens size (2.30mm x 1.60mm), and mounting type (Surface Mount) must match exactly.

Electrical Compatibility: Forward voltage (3.2V typical), test current (20mA), and color (Green) must be identical.

Optical Compatibility: Lens transparency (Clear) and lens style (Rectangle with Flat Top) must match.

Regulatory Compliance: RoHS3 compliance and REACH unaffected status are required.

Parts meeting these criteria are classified as direct substitutes regardless of differences in millicandela rating, wavelength specifications, product status, or moisture sensitivity level, provided the core electrical and mechanical parameters align.

Parameter Comparison

Engineering Selection Recommendations

Both S7L012EC4TT86R and SML012ENTT86 are qualified substitutes for the obsolete SML012EC4TT86 based on matching mechanical, electrical, and optical parameters.

S7L012EC4TT86R is classified as a direct manufacturer substitute with active product status. This part maintains full compatibility with existing designs and PCB layouts. Moisture sensitivity level MSL 3 (168 hours) provides improved handling characteristics compared to the original MSL 4 specification.

SML012ENTT86 is the manufacturer-recommended replacement, also with active product status. This part is supplied in Tape & Reel (TR) packaging and offers higher brightness output (360mcd versus 140mcd original specification) while maintaining identical electrical and mechanical parameters. The improved millicandela rating provides enhanced visibility margin in indicator applications. Moisture sensitivity level MSL 3 (168 hours) matches the direct substitute.

Both parts maintain ROHS3 compliance and REACH unaffected status. Selection between the two substitutes depends on brightness requirements, packaging format preference, and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can S7L012EC4TT86R and SML012ENTT86 be used interchangeably with SML012EC4TT86?

A: Both parts are electrically and mechanically compatible substitutes. They share identical forward voltage (3.2V), test current (20mA), package dimensions (1208/3020 Metric), and physical form factor. PCB layouts and circuit designs require no modification.

Q: What is the difference between the two substitute parts?

A: S7L012EC4TT86R is a direct substitute with unspecified brightness. SML012ENTT86 is the manufacturer-recommended replacement offering 360mcd brightness versus the original 140mcd. Both maintain identical electrical and mechanical specifications. SML012ENTT86 is supplied in Tape & Reel packaging.

Q: Does the higher millicandela rating of SML012ENTT86 affect circuit compatibility?

A: No. The increased brightness (360mcd) results from improved LED die efficiency and does not alter electrical parameters. Forward voltage and test current remain 3.2V and 20mA respectively. Existing circuit designs operate without modification.

Q: Are there packaging considerations when selecting a substitute?

A: SML012ENTT86 is supplied in Tape & Reel (TR) format, suitable for automated assembly. S7L012EC4TT86R packaging format is not specified in available data. Confirm packaging compatibility with your assembly process requirements.

Q: What is the impact of different Moisture Sensitivity Levels?

A: Both substitutes carry MSL 3 (168 hours) versus the original MSL 4 (72 hours). MSL 3 indicates improved moisture tolerance and extended floor life after package opening, reducing risk of moisture-induced failures during storage and assembly.

Q: Are regulatory certifications maintained with these substitutes?

A: Both substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the original part's regulatory standing.
