Substitute Part Grouping Explanation

Substitution analysis for the LG L29K-G2J1-24-Z is based on the following critical parameters: package type (0603 surface mount), mounting compatibility, lens transparency (diffused), and electrical operating characteristics (forward voltage, test current, and luminous intensity).

The identified substitute part HSMW-C191 shares the following compatible parameters:

• Package / Case: 0603 (1608 Metric)
• Mounting Type: Surface Mount
• Lens Color: White
• Lens Transparency: Diffused
• Lens Style: Rectangle with Flat Top
• RoHS Status: ROHS3 Compliant
• HTSUS Classification: 8541.41.0000

However, the HSMW-C191 differs in color specification (white versus green), forward voltage (3.6V versus 1.7V), test current (20mA versus 2mA), and luminous intensity (200mcd versus 3.92mcd). These differences indicate that while the HSMW-C191 occupies the same physical footprint and mounting interface, it is not a direct functional equivalent and requires circuit design modifications for implementation.

Parameter Comparison

Engineering Selection Recommendations

The LG L29K-G2J1-24-Z is designated as Not For New Designs, indicating end-of-life status within the ams-OSRAM product portfolio. The HSMW-C191 from Broadcom Limited maintains active product status and is available in production quantities.

Both components satisfy ROHS3 compliance, REACH unaffected status, and EAR99 export classification requirements. Both are classified under identical HTSUS code 8541.41.0000.

Physical compatibility is confirmed: both components utilize 0603 (1608 Metric) surface mount packages with identical width dimensions (0.80mm) and comparable length and height specifications, permitting direct PCB footprint reuse without layout modification.

Electrical compatibility requires circuit design evaluation. The HSMW-C191 operates at 3.6V forward voltage compared to the LG L29K-G2J1-24-Z at 1.7V, and draws 20mA test current versus 2mA. The HSMW-C191 provides significantly higher luminous intensity (200mcd versus 3.92mcd). These differences necessitate resistor value recalculation and power supply voltage verification before implementation.

Color specification differs: the LG L29K-G2J1-24-Z emits green light at 570nm dominant wavelength, while the HSMW-C191 emits cool white light. Application-specific color requirements must be evaluated independently.

Frequently Asked Questions (FAQ)

Q: Can the HSMW-C191 be used as a direct replacement for the LG L29K-G2J1-24-Z without circuit modifications?

A: No. While both components share identical 0603 surface mount package dimensions and footprints, the HSMW-C191 operates at 3.6V forward voltage versus 1.7V for the LG L29K-G2J1-24-Z. Additionally, the HSMW-C191 requires 20mA test current compared to 2mA for the original part. Current-limiting resistor values must be recalculated, and power supply voltage compatibility must be verified before implementation.

Q: Are there color compatibility considerations between these two parts?

A: Yes. The LG L29K-G2J1-24-Z emits green light at 570nm dominant wavelength with diffused lens transparency. The HSMW-C191 emits cool white light. If the application requires green light indication specifically, the HSMW-C191 is not functionally equivalent. Color selection must be based on application requirements.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both the LG L29K-G2J1-24-Z and HSMW-C191 are ROHS3 compliant, REACH unaffected, classified as EAR99 for export control, and assigned identical HTSUS code 8541.41.0000.

Q: What is the significance of the LG L29K-G2J1-24-Z being marked as Not For New Designs?

A: This designation indicates that ams-OSRAM has discontinued active development and promotion of this component for new applications. Existing inventory may remain available for legacy system support, but the manufacturer recommends alternative components for new designs. The HSMW-C191 represents an active alternative from a different manufacturer.

Q: Are the physical dimensions identical between these two parts?

A: The components share the same 0603 (1608 Metric) package classification and identical width (0.80mm). Length dimensions are 1.70mm (LG L29K-G2J1-24-Z) versus 1.60mm (HSMW-C191), and height dimensions are 0.65mm (LG L29K-G2J1-24-Z) versus 0.60mm (HSMW-C191). These minor dimensional variations remain within standard 0603 package tolerances and do not prevent PCB footprint reuse.

Q: What is the difference in luminous intensity between these two parts?

A: The LG L29K-G2J1-24-Z provides 3.92mcd at 2mA test current. The HSMW-C191 provides 200mcd at 20mA test current. The HSMW-C191 delivers significantly higher brightness. Application brightness requirements must be evaluated to determine if the increased intensity is acceptable or requires additional circuit design modifications such as current limiting.

Q: Can the viewing angle difference affect substitution decisions?

A: The LG L29K-G2J1-24-Z provides 160° viewing angle, while the HSMW-C191 provides 140° viewing angle. This 20° difference may be significant in applications requiring wide-angle light distribution. Application-specific viewing angle requirements should be confirmed before substitution.
