Key Parameters

Substitute Part Grouping Explanation

Substitution of the SM1206SBWC-IL is determined by strict equivalence across the following critical parameters:

Optical Characteristics: Wavelength dominant (470nm), wavelength peak (468nm), color (blue), lens style (round with flat top), lens size (1.10mm diameter), lens color (colorless), and lens transparency (clear) must remain identical.

Electrical Characteristics: Forward voltage (3.3V typical), test current (20mA), and viewing angle (30°) must match exactly.

Brightness: Millicandela rating of 225mcd must be maintained.

Physical & Mechanical: Package type (1206/3216 Metric), dimensions (3.20mm L x 1.60mm W), maximum height (1.40mm), and surface mount mounting type must be identical.

Environmental: Moisture sensitivity level (MSL 4, 72 Hours) must be equivalent.

The SM1206BWC-IL meets all these criteria and is identified as a parametric equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

The SM1206BWC-IL is a direct parametric equivalent to the SM1206SBWC-IL. All optical, electrical, mechanical, and environmental specifications are identical. The primary distinction is product status: the main part is obsolete while the substitute is active in production.

The SM1206BWC-IL is supplied in Tape & Reel (TR) packaging format, which differs from the bulk packaging of the original part. This packaging format is standard for high-volume surface mount assembly operations and is compatible with automated pick-and-place equipment.

The substitute part carries ROHS3 compliance certification, confirming adherence to current environmental and hazardous substance restrictions. This certification status should be verified against your specific application requirements and regional compliance mandates.

For applications requiring the original bulk packaging format, contact the manufacturer directly regarding availability of SM1206BWC-IL in alternative packaging configurations.

Frequently Asked Questions (FAQ)

Q: Can SM1206BWC-IL be used as a direct replacement for SM1206SBWC-IL?

A: Yes. The SM1206BWC-IL meets all parametric specifications of the SM1206SBWC-IL, including wavelength (470nm dominant, 468nm peak), forward voltage (3.3V), test current (20mA), brightness (225mcd), viewing angle (30°), lens configuration, package dimensions, and moisture sensitivity level. The parts are electrically and mechanically interchangeable.

Q: What is the difference between the two part numbers?

A: The primary differences are product status and packaging format. SM1206SBWC-IL is obsolete and supplied in bulk packaging. SM1206BWC-IL is active in production and supplied in Tape & Reel (TR) format. All functional and dimensional specifications are identical.

Q: Is the Tape & Reel packaging compatible with my assembly process?

A: Tape & Reel (TR) packaging is the standard format for surface mount component assembly using automated pick-and-place equipment. If your process requires bulk packaging, contact Bivar Inc. to determine availability of alternative packaging options for the SM1206BWC-IL.

Q: Does the substitute part meet RoHS compliance requirements?

A: The SM1206BWC-IL carries ROHS3 compliance certification. Verify this certification status against your specific application and regional regulatory requirements.

Q: Are there any circuit design changes required when substituting SM1206BWC-IL for SM1206SBWC-IL?

A: No circuit design changes are required. The substitute part maintains identical electrical characteristics, including forward voltage (3.3V) and test current (20mA). PCB layout and schematic connections remain unchanged.

Q: What is the MSL rating and how does it affect handling?

A: Both parts carry MSL 4 (72 Hours) rating. This indicates the component can be exposed to moisture for up to 72 hours at specified temperature and humidity conditions before soldering. Standard moisture control procedures during storage and assembly apply.
