Substitute Part Grouping Explanation

Substitution of the AM23SGD3-F is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Forward voltage (2.2V typical), test current (20mA), millicandela rating (8mcd), dominant wavelength (568nm), and peak wavelength (565nm) must remain identical.

Optical Parameters: Color (green), lens transparency (diffused), viewing angle (140°), and lens style (rectangle with flat top) must be maintained.

Mechanical Parameters: Package designation (TO-236-3, SC-59, SOT-23-3), mounting type (surface mount), lens size (3.00mm L x 1.30mm W), and maximum height (1.20mm) must be compatible.

Compliance Parameters: RoHS3 compliance and MSL rating (3, 168 Hours) must be equivalent.

Manufacturer: Kingbright as the original manufacturer.

The substitute part AM23SGD-F meets all these criteria and is classified as a parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both AM23SGD3-F and AM23SGD-F are active production parts from Kingbright with identical electrical, optical, and mechanical specifications. Selection between these parts is based on the following engineering criteria:

Compliance: Both parts maintain ROHS3 compliance and equivalent MSL ratings, ensuring regulatory and environmental requirements are met in manufacturing and field deployment.

Availability: The substitute part AM23SGD-F has higher inventory availability (1711 pieces versus 1127 pieces), which may influence procurement lead times and supply chain continuity.

Package Compatibility: Both parts use identical SOT-23-3 packaging with matching mechanical dimensions (3.00mm L x 1.30mm W, 1.20mm max height), ensuring direct PCB layout compatibility without redesign.

Electrical Performance: Identical forward voltage (2.2V), test current (20mA), and wavelength specifications (568nm dominant, 565nm peak) ensure equivalent circuit performance and optical output in indication applications.

Optical Characteristics: Both parts deliver 8mcd brightness with 140° viewing angle in diffused green lens configuration, maintaining consistent visual indication performance.

Either part may be selected for new designs or as a replacement component in existing applications without circuit modification or performance degradation.

Frequently Asked Questions (FAQ)

Q: Can AM23SGD-F be used as a direct replacement for AM23SGD3-F in existing designs?

A: Yes. Both parts are parametric equivalents with identical electrical specifications (2.2V forward voltage, 20mA test current), optical output (8mcd, 568nm wavelength), and mechanical packaging (SOT-23-3, 3.00mm x 1.30mm lens size). No circuit redesign is required.

Q: Are there differences in the package designation between these parts?

A: Both parts use the same package family: TO-236-3, SC-59, SOT-23-3. The supplier device package designation differs slightly (SOT-23 versus SOT-23-3), but this reflects internal supplier documentation and does not affect physical or electrical compatibility.

Q: What is the significance of the MSL rating for these LEDs?

A: Both parts carry MSL 3 (168 Hours) rating, indicating moisture sensitivity level 3 with a floor life of 168 hours after bag opening. This specification applies to storage and handling conditions prior to soldering and does not affect post-assembly performance.

Q: Do both parts meet the same compliance standards?

A: Yes. Both AM23SGD3-F and AM23SGD-F are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.

Q: Is there a performance difference in brightness or color between these parts?

A: No. Both parts deliver identical millicandela rating (8mcd), dominant wavelength (568nm), peak wavelength (565nm), and viewing angle (140°). Optical performance is equivalent.

Q: Which part should be selected for new production designs?

A: Either part is suitable for new designs. Selection may be based on current inventory availability, supplier lead times, or existing supply chain relationships. The AM23SGD-F currently has higher inventory availability (1711 pieces).

Q: Are there any restrictions on mixing these parts in the same production batch?

A: No. Both parts are electrically and mechanically identical and may be used interchangeably within the same assembly or production batch without performance variation or compatibility issues.
