HSML-C130 Equivalent & Substitute Parts

Part Overview

The HSML-C130 is an orange diffused SMD LED manufactured by Broadcom Limited, designed for indication applications in 0603 (1608 Metric) surface mount packages. This component features a dominant wavelength of 606nm with a forward voltage of 1.94V at 20mA test current and a brightness rating of 139mcd. The product is currently obsolete, making identification of compatible substitute components essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HSML-C130 is determined by the following critical parameters:

Package Compatibility: The substitute must use the 0603 (1608 Metric) surface mount package with identical physical dimensions (1.60mm L x 0.80mm W, 0.35mm max height) to ensure PCB footprint compatibility.

Optical Characteristics: The substitute must emit orange light in the visible spectrum. The dominant wavelength range of 605–606nm and peak wavelength range of 611–612nm are acceptable for indication applications where color consistency is required.

Electrical Parameters: Forward voltage (Vf) tolerance and test current determine circuit compatibility. The HSML-C130 operates at 1.94V / 20mA; substitutes with Vf between 1.94V and 2.0V and test currents between 5mA and 20mA are functionally compatible within standard LED driver circuits.

Brightness and Viewing Angle: Millicandela rating and viewing angle affect visibility in the application. Substitutes with lower brightness (28.1mcd vs. 139mcd) or wider viewing angles (130° vs. 110°) remain functionally suitable for indication purposes.

Lens Properties: Both diffused and clear lens options are acceptable for orange indication LEDs, as lens transparency does not affect substitution eligibility in indication circuits.

Parameter Comparison

Engineering Selection Recommendations

The LTST-C193KFKT-5A from Lite-On Inc. is a direct substitute for the obsolete HSML-C130. Both components share identical package dimensions, mounting type, and regulatory compliance status (REACH Unaffected, EAR99 classification, identical HTSUS code). The substitute is currently in active production with high inventory availability (59,400 pcs), ensuring supply chain continuity.

The LTST-C193KFKT-5A operates at 2V forward voltage compared to the HSML-C130's 1.94V, a difference of 0.06V that falls within standard LED circuit tolerance. The test current is specified at 5mA versus 20mA for the main part; this reflects the substitute's lower brightness rating (28.1mcd vs. 139mcd) and does not affect substitution eligibility. Both components maintain identical MSL ratings (2A, 4 Weeks) and are suitable for identical PCB assembly processes.

The substitute features a clear lens versus the diffused lens of the main part and a wider viewing angle (130° vs. 110°). These optical differences do not prevent substitution in indication applications where color consistency is the primary requirement.

Frequently Asked Questions (FAQ)

Q: Can the LTST-C193KFKT-5A replace the HSML-C130 on existing PCBs without layout modifications?

A: Yes. Both components use the 0603 (1608 Metric) package with identical physical dimensions (1.60mm L x 0.80mm W, 0.35mm max height). PCB footprints are directly compatible without layout changes.

Q: What is the impact of the forward voltage difference (1.94V vs. 2V)?

A: The 0.06V difference is within standard LED circuit design tolerance. Existing driver circuits designed for the HSML-C130 will operate the LTST-C193KFKT-5A without modification. Both components are rated for identical MSL conditions and assembly processes.

Q: How does the brightness difference (139mcd vs. 28.1mcd) affect substitution?

A: The LTST-C193KFKT-5A has lower brightness due to its lower test current specification (5mA vs. 20mA). For indication applications where the LED serves as a status indicator, this brightness level remains functionally adequate. Applications requiring specific brightness levels should evaluate the substitute's performance in the target circuit.

Q: Why does the substitute have a clear lens instead of diffused?

A: Lens transparency is not a substitution-limiting parameter for orange indication LEDs. Both diffused and clear lenses emit the same orange color (605–606nm dominant wavelength). The clear lens of the LTST-C193KFKT-5A provides a sharper light point, while the diffused lens of the HSML-C130 provides more dispersed illumination. Selection depends on the specific visual appearance required in the application.

Q: Is the LTST-C193KFKT-5A available in the same packaging format?

A: The LTST-C193KFKT-5A is supplied in Tape & Reel (TR) format, which is standard for high-volume production. The HSML-C130 packaging format was not specified in the available data. Both formats are compatible with automated PCB assembly equipment.

Q: Are there any regulatory or compliance differences between the two parts?

A: No. Both components share identical regulatory status: REACH Unaffected, EAR99 ECCN classification, and 8541.41.0000 HTSUS code. Both maintain 2A MSL ratings (4 Weeks). No additional compliance documentation is required for substitution.
