HSML-C120 Equivalent & Substitute Parts

Part Overview

The HSML-C120 is an orange 605nm LED indication component manufactured by Broadcom Limited, designed for surface mount right-angle applications. This 2-SMD, no-lead chip LED operates at 1.9V forward voltage with a 90mcd brightness rating and features a clear rectangular domed lens measuring 1.20mm x 0.60mm. The component is actively produced and ROHS3 compliant, making it suitable for modern electronic assemblies requiring discrete LED indication in compact form factors.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the allowed parameter tolerances for this product category. Substitution becomes necessary when the primary part experiences supply constraints, extended lead times, or when design requirements permit alternative configurations that meet functional specifications.

Substitute Part Grouping Explanation

Substitute parts for the HSML-C120 are grouped based on the following allowed substitution parameters:

Primary Substitution Criteria:

• Wavelength range: 605nm ± tolerance (orange spectrum)
• Forward voltage: 1.9V nominal
• Mounting type: Surface mount configurations
• Package classification: 2-SMD, no-lead form factors
• RoHS3 compliance and active product status

Substitution Logic:

The HSML-C120 accepts three classified substitutes:

1. SML-P11DTT86R – Orange 605nm LED with matching forward voltage (1.9V) and wavelength. Differs in package size (0402/1006 metric), test current (1mA vs 20mA), and brightness rating (7.3mcd vs 90mcd). Suitable for applications where reduced brightness and compact footprint are acceptable.

2. SML-A12WTT86J – Yellow 590nm LED with 2V forward voltage and 63mcd brightness. Differs in color (yellow vs orange), wavelength (590nm vs 605nm), and lens configuration (flat top vs domed). Acceptable where color shift to yellow and increased forward voltage are compatible with circuit design.

3. SML-P11YTT86R – Yellow 586nm LED with 1.9V forward voltage matching the main part. Differs in color (yellow vs orange), wavelength (586nm vs 605nm), and brightness (7.6mcd vs 90mcd). Suitable for applications permitting yellow indication and reduced brightness output.

All substitutes maintain ROHS3 compliance and active product status.

Parameter Comparison

Engineering Selection Recommendations

Selection of substitute parts for the HSML-C120 must be based on the specific application requirements and circuit design constraints:

SML-P11DTT86R Selection: This substitute maintains identical wavelength (605nm orange) and forward voltage (1.9V) as the HSML-C120. The primary trade-off is reduced brightness (7.3mcd vs 90mcd) and significantly smaller package footprint (0402 metric). This part is suitable for applications where PCB space is constrained and brightness reduction is acceptable. The lower test current (1mA vs 20mA) indicates operation at reduced power levels. ROHS3 compliance and active product status are maintained.

SML-A12WTT86J Selection: This substitute introduces a color shift to yellow (590nm) and increases forward voltage to 2V. The brightness rating (63mcd) falls between the main part and the PicoLED alternatives. This part maintains the right-angle mounting configuration and similar overall dimensions. Selection is appropriate only when circuit design permits yellow indication and the 2V forward voltage is compatible with the LED driver circuit. ROHS3 compliance and active product status are maintained.

SML-P11YTT86R Selection: This substitute maintains the 1.9V forward voltage of the HSML-C120 but shifts color to yellow (586nm) and reduces brightness to 7.6mcd. The compact 0402 package footprint matches SML-P11DTT86R. Selection is appropriate for space-constrained applications where yellow indication and reduced brightness are acceptable. ROHS3 compliance and active product status are maintained.

All substitutes carry ROHS3 compliance certification and active product status, meeting regulatory requirements equivalent to the primary part.

Frequently Asked Questions (FAQ)

Q: Can SML-P11DTT86R be used as a direct replacement for HSML-C120?

A: SML-P11DTT86R maintains the same wavelength (605nm orange) and forward voltage (1.9V) as the HSML-C120, making it electrically compatible. However, the package size differs significantly (0402 metric vs 2-SMD), and brightness is reduced to 7.3mcd. PCB layout modifications are required, and brightness reduction must be acceptable for the application.

Q: What is the primary difference between SML-A12WTT86J and the other substitutes?

A: SML-A12WTT86J is the only substitute that maintains the right-angle mounting configuration and similar overall dimensions to the HSML-C120. However, it introduces a color shift to yellow (590nm) and increases forward voltage to 2V. This part is suitable when color change is acceptable and the circuit can accommodate the higher forward voltage.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All three substitute parts—SML-P11DTT86R, SML-A12WTT86J, and SML-P11YTT86R—carry ROHS3 compliance certification, matching the regulatory status of the HSML-C120.

Q: Which substitute offers the closest brightness match to HSML-C120?

A: SML-A12WTT86J provides the closest brightness match at 63mcd, compared to the HSML-C120's 90mcd rating. The PicoLED alternatives (SML-P11DTT86R and SML-P11YTT86R) operate at significantly reduced brightness levels (7.3mcd and 7.6mcd respectively) due to their lower test current specifications.

Q: Can forward voltage differences affect circuit compatibility?

A: Yes. SML-A12WTT86J operates at 2V forward voltage, compared to 1.9V for the HSML-C120. This 0.1V difference may require LED driver circuit adjustment. SML-P11DTT86R and SML-P11YTT86R maintain the 1.9V specification and do not require voltage adjustment.

Q: What are the package implications of selecting SML-P11DTT86R or SML-P11YTT86R?

A: Both PicoLED parts use the 0402 (1006 metric) package, which is significantly smaller than the HSML-C120's 2-SMD form factor. PCB footprint redesign is required. The reduced height (0.25mm vs 0.60mm) may also affect mechanical clearance considerations in the assembly.

Q: Are there inventory considerations for these substitutes?

A: Inventory levels vary. HSML-C120 has 4300 units in stock, SML-P11DTT86R has 11095 units, SML-A12WTT86J has 809 units, and SML-P11YTT86R has 2118 units. Availability should be confirmed for production requirements.
