HSMD-S690 Equivalent & Substitute Parts

Part Overview

The HSMD-S690 is an orange diffused SMD LED from Broadcom Limited's SunPower series, designed for indication applications with a dominant wavelength of 605nm. This component features a 0603 (1608 Metric) package with a forward voltage of 1.9V at 20mA test current and a brightness rating of 65mcd. The product is currently obsolete, necessitating identification of functionally equivalent alternatives for ongoing design support and production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HSMD-S690 is determined by the following critical parameters:

Primary Matching Criteria:

• Package / Case: 0603 (1608 Metric)
• Mounting Type: Surface Mount
• Color: Orange
• Wavelength - Dominant: 605nm (±1nm tolerance acceptable)
• Voltage - Forward (Vf): 1.9V (±0.3V acceptable for circuit compatibility)
• Current - Test: 20mA
• Lens Transparency: Diffused

Secondary Compatibility Factors:

• Millicandela Rating: 65mcd (brightness level for indication applications)
• Viewing Angle: 165° minimum
• Physical dimensions: 1.60mm L x 0.80mm W
• Moisture Sensitivity Level: 2A or better

The substitute parts identified meet these criteria with minor variations in lens color, lens size, and viewing angle that do not affect functional equivalence in indication circuit applications.

Parameter Comparison

Engineering Selection Recommendations

HSMD-C191 (Broadcom Limited): This substitute maintains Broadcom manufacturer continuity and active product status. It shares identical package, mounting type, and physical dimensions with the HSMD-S690. The forward voltage increases to 2.2V, which requires circuit verification for current-limiting resistor adjustment. The brightness rating of 8mcd is significantly lower than the original 65mcd, making this option suitable only for applications where reduced brightness is acceptable. ROHS3 compliance and 2A MSL rating match the original specifications. Packaging is Tape & Reel (TR).

5975213402F (Dialight): This Dialight substitute provides exact wavelength and forward voltage matching (605nm, 1.9V) with identical brightness rating (65mcd). The 0603 package and surface mount configuration are preserved. The viewing angle of 152° is narrower than the original 165°, which may affect visibility in wide-angle indication applications. MSL rating is 3 (168 Hours), representing a less stringent moisture sensitivity specification. Packaging is Strip format.

5975213407F (Dialight): This Dialight substitute is electrically and optically identical to the 5975213402F, with the same wavelength (605nm), forward voltage (1.9V), and brightness (65mcd). The primary distinction is packaging format: Tape & Reel (TR) instead of Strip. All other parameters, including the 152° viewing angle and MSL 3 rating, remain consistent. This option is preferred for high-volume production requiring automated assembly.

Recommendation Priority:

• For direct electrical and optical replacement: 5975213407F or 5975213402F (Dialight)
• For manufacturer continuity with brightness reduction acceptable: HSMD-C191 (Broadcom Limited)

Frequently Asked Questions (FAQ)

Q: Can HSMD-C191 be used as a direct replacement for HSMD-S690?

A: HSMD-C191 is mechanically and electrically compatible but with important limitations. The forward voltage increases from 1.9V to 2.2V, requiring recalculation of series resistor values in the LED circuit. The brightness rating drops from 65mcd to 8mcd, which is a significant reduction suitable only for applications where lower brightness is acceptable or where the LED is used in high-ambient-light conditions where the original brightness was excessive.

Q: What is the difference between 5975213402F and 5975213407F?

A: Both Dialight parts are electrically and optically identical. The sole difference is packaging format: 5975213402F is supplied in Strip packaging, while 5975213407F is supplied in Tape & Reel (TR) format. Selection depends on assembly process requirements. Tape & Reel is standard for automated pick-and-place assembly, while Strip packaging is suitable for manual or semi-automated processes.

Q: Are there viewing angle differences that affect circuit performance?

A: The HSMD-S690 has a 165° viewing angle, while both Dialight substitutes (5975213402F and 5975213407F) have 152° viewing angles. This 13° reduction may affect applications requiring wide-angle visibility, such as indicator panels viewed from extreme angles. HSMD-C191 offers a 170° viewing angle, which exceeds the original specification. Evaluate viewing angle requirements based on the specific application geometry.

Q: What is the impact of MSL rating differences?

A: The HSMD-S690 and HSMD-C191 both have MSL 2A (4 Weeks), while the Dialight substitutes have MSL 3 (168 Hours). MSL 3 indicates less stringent moisture sensitivity, allowing longer shelf life and storage time before soldering. For most applications, this difference is not critical, but in high-humidity environments or extended storage scenarios, the lower MSL rating of Dialight parts may require additional moisture control measures.

Q: Is RoHS compliance a factor in selecting a substitute?

A: All active substitute parts (HSMD-C191, 5975213402F, 5975213407F) are ROHS3 compliant. The original HSMD-S690 RoHS status is not specified due to its obsolete status. For applications requiring RoHS compliance documentation, all three substitutes meet this requirement.

Q: Can I use these substitutes interchangeably in existing designs?

A: Electrical interchangeability depends on forward voltage tolerance. The Dialight parts (5975213402F and 5975213407F) maintain the original 1.9V forward voltage and require no circuit modification. HSMD-C191 requires resistor recalculation due to its 2.2V forward voltage. Optical interchangeability is affected by brightness and viewing angle differences. Evaluate both factors before finalizing a design change.
