Parameter Comparison

Engineering Selection Recommendations

SML-LX15HC-RP-TR is a direct parametric equivalent to SML-LX15HC-TR. Both parts share identical electrical characteristics, mechanical dimensions, and compliance certifications. The parts differ only in packaging format and moisture sensitivity level.

Packaging Consideration: SML-LX15HC-TR is supplied in Tape and Reel (TR) format, while SML-LX15HC-RP-TR is supplied in Cut Tape (CT) format. Selection between these formats depends on assembly process requirements and volume specifications.

Moisture Sensitivity Consideration: SML-LX15HC-TR carries MSL 2 (1 Year shelf life), while SML-LX15HC-RP-TR carries MSL 3 (168 Hours shelf life). This difference affects storage and handling protocols but does not impact functional performance in the application.

Both parts maintain Active product status and full compliance with ROHS3 and REACH regulations, making either suitable for production applications.

Frequently Asked Questions (FAQ)

Q: Can SML-LX15HC-RP-TR be used as a direct replacement for SML-LX15HC-TR?

A: Yes. Both parts are parametric equivalents with identical electrical performance (2V forward voltage, 20mA test current, 5mcd brightness, 700nm peak wavelength), identical mechanical dimensions (3.00mm x 3.00mm x 1.00mm max height), and identical SOT-23 package specifications. The parts differ only in packaging format (Tape and Reel vs. Cut Tape) and moisture sensitivity level.

Q: What is the difference between Tape and Reel (TR) and Cut Tape (CT) packaging?

A: Tape and Reel (TR) packaging supplies components on continuous tape wound on a reel, suitable for high-volume automated assembly. Cut Tape (CT) packaging supplies components on tape segments cut to specific lengths, suitable for lower-volume or manual assembly processes. Both formats contain identical components.

Q: Does the difference in Moisture Sensitivity Level (MSL) affect circuit performance?

A: No. MSL ratings specify storage and handling requirements prior to assembly, not functional performance. SML-LX15HC-TR (MSL 2, 1 Year) allows longer shelf storage than SML-LX15HC-RP-TR (MSL 3, 168 Hours). Once soldered into the circuit, both parts perform identically.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both SML-LX15HC-TR and SML-LX15HC-RP-TR are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, provided the assembly process accommodates the packaging format. If the design uses automated pick-and-place equipment configured for Tape and Reel format, SML-LX15HC-TR is appropriate. If manual assembly or Cut Tape-compatible equipment is used, SML-LX15HC-RP-TR is appropriate. Electrical and mechanical performance are identical.

Q: What is the viewing angle specification, and does it affect placement on the PCB?

A: Both parts have a 140° viewing angle, indicating the LED is visible across a wide horizontal range. This specification does not affect PCB placement but determines the application suitability for indication purposes where wide visibility is required.
