LS L296-P2Q2-1-Z Equivalent & Substitute Parts

Part Overview

The LS L296-P2Q2-1-Z is a red diffused LED in 0603 (1608 Metric) surface mount package manufactured by ams-OSRAM USA INC. This component is designated as Not For New Designs, indicating it has reached end-of-life status. The part operates at 2V forward voltage with a 630nm dominant wavelength and delivers 84mcd luminous intensity. Due to its discontinued design status, identification of functionally equivalent substitute components is necessary for ongoing production support and design continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LS L296-P2Q2-1-Z is determined by the following critical parameters:

Package Compatibility: Both the main part and substitute must use the 0603 (1608 Metric) surface mount package to ensure PCB footprint compatibility and automated assembly process alignment.

Optical Characteristics: Red color classification and diffused lens transparency must be maintained. Wavelength specifications (dominant and peak) must fall within the red spectrum range (620nm–640nm) to preserve intended indication functionality.

Electrical Parameters: Forward voltage (Vf) must be within ±0.2V of the main part specification to ensure circuit compatibility without redesign. Test current of 20mA establishes the baseline for luminous intensity comparison.

Luminous Intensity: Millicandela rating must meet or exceed 80mcd to maintain visibility performance in the intended application context.

Regulatory Compliance: RoHS3 compliance is mandatory. REACH Unaffected status must be maintained.

The HSMC-C191 from Broadcom Limited qualifies as a substitute based on these criteria.

Parameter Comparison

Engineering Selection Recommendations

The HSMC-C191 is a direct substitute for the LS L296-P2Q2-1-Z based on the following engineering criteria:

Package and Footprint: Both components use identical 0603 (1608 Metric) surface mount packaging. The dimensional differences (0.1mm length, 0.05mm height) are within standard PCB assembly tolerances and do not require footprint modification.

Electrical Compatibility: The forward voltage difference of 0.1V (1.9V versus 2V) is within acceptable circuit design margins for LED indication applications. Both parts operate at 20mA test current, ensuring consistent circuit behavior.

Optical Performance: The HSMC-C191 delivers 90mcd luminous intensity compared to 84mcd for the main part, providing equivalent or superior visibility. The dominant wavelength difference of 4nm (626nm versus 630nm) remains within the red spectrum and produces visually equivalent indication color.

Regulatory Status: The HSMC-C191 maintains ROHS3 compliance and REACH Unaffected status, meeting all regulatory requirements of the original part. The substitute is an active production component, ensuring long-term availability and supply chain stability.

Packaging Format: The main part is supplied in Tape & Reel (TR) format, while the substitute is available in Cut Tape (CT) & Digi-Reel® format. Both formats are standard for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the HSMC-C191 be used as a direct replacement without circuit modification?

A: Yes. The 0.1V forward voltage difference falls within standard LED circuit design tolerances. No circuit redesign is required for typical indication applications.

Q: Are there any PCB layout considerations when switching from LS L296-P2Q2-1-Z to HSMC-C191?

A: No layout changes are necessary. Both components use the 0603 (1608 Metric) package with identical footprints. The minor dimensional differences (0.1mm length, 0.05mm height) do not affect PCB assembly or component placement.

Q: Will the visual appearance of the LED indication change?

A: The visual appearance remains consistent. Both parts are red diffused LEDs with wavelengths in the same spectrum range (626nm versus 630nm). The human eye cannot distinguish this 4nm difference. The HSMC-C191 provides slightly higher luminous intensity (90mcd versus 84mcd), which may result in marginally brighter indication.

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

A: Both are standard formats for automated assembly. Tape & Reel is continuous reel packaging, while Cut Tape & Digi-Reel® provides pre-cut tape segments. Both formats are compatible with standard pick-and-place equipment.

Q: Is the HSMC-C191 available for long-term production use?

A: Yes. The HSMC-C191 is designated as Active product status, indicating it is in current production and available for new designs and ongoing production support. The original LS L296-P2Q2-1-Z is Not For New Designs, making the HSMC-C191 the recommended choice for production continuity.

Q: Are there any moisture sensitivity differences between the two parts?

A: The main part has MSL 2 (1 Year) rating, while the substitute has MSL 2A (4 Weeks) rating. Both are MSL 2 classification. The substitute requires slightly more careful handling during storage and assembly, with a shorter shelf life window.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both the LS L296-P2Q2-1-Z and HSMC-C191 are ROHS3 compliant and REACH Unaffected, meeting identical regulatory requirements.
