Dialight 5973308202F LED Green Clear 2-PLCC SMD Equivalent & Substitute Parts

Part Overview

The Dialight 5973308202F is an active green LED indication component in 2-PLCC surface mount package, featuring a 570nm dominant wavelength and 1.8V forward voltage rating. This discrete LED is designed for standard indication applications requiring low-power operation at 2mA test current. The component is ROHS3 compliant and maintains active product status with 718 units in current inventory. Substitute parts are identified when equivalent optical, electrical, and mechanical characteristics are required due to supply constraints, design flexibility, or application-specific performance needs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Dialight 5973308202F is determined by strict alignment of the following critical parameters:

Optical Compatibility: Color (Green), wavelength range (dominant wavelength 569–570nm), and viewing angle (120°) must remain constant to preserve indication visibility and application performance.

Electrical Compatibility: Forward voltage (Vf) tolerance and test current define circuit integration requirements. The Dialight part operates at 1.8V / 2mA; substitute parts must operate within compatible voltage and current ranges to function in existing driver circuits without modification.

Mechanical Compatibility: Package type (2-PLCC), mounting method (Surface Mount), lens style (Round with Flat Top), and physical dimensions (3.20 x 2.80mm footprint, ≤2.11mm height) ensure PCB layout and assembly compatibility.

Regulatory Compliance: RoHS3 compliance and REACH unaffected status are mandatory for equivalent substitution in regulated applications.

The Broadcom Limited HSMG-A100-H01J1 qualifies as a substitute based on matching optical characteristics (green color, 569nm dominant wavelength, 120° viewing angle), identical package and mounting specifications, and equivalent regulatory compliance. Electrical parameter differences (2.2V / 20mA vs. 1.8V / 2mA) require circuit evaluation for driver compatibility.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (Dialight 5973308202F): Maintain original specification when supply is available. Active product status and established inventory support continuity. ROHS3 compliance and REACH unaffected status confirm regulatory alignment.

Substitute Selection (Broadcom HSMG-A100-H01J1): Acceptable when Dialight part is unavailable. Optical and mechanical parameters are equivalent. Electrical differences require circuit validation: the Broadcom part operates at 2.2V forward voltage and 20mA test current versus the Dialight 1.8V / 2mA specification. Driver circuits must accommodate the higher voltage and current requirements. Moisture sensitivity level differs (MSL 2A vs. MSL 2); storage and handling procedures may require adjustment. Higher millicandela rating (8mcd vs. 6.28mcd) provides increased brightness margin.

Both parts maintain ROHS3 compliance and REACH unaffected status, confirming suitability for regulated applications.

Frequently Asked Questions (FAQ)

Q: Can the Broadcom HSMG-A100-H01J1 directly replace the Dialight 5973308202F without circuit modification?

A: Direct replacement requires circuit evaluation. The Broadcom part requires 2.2V forward voltage and 20mA test current compared to the Dialight specification of 1.8V and 2mA. Existing driver circuits designed for the Dialight part may not provide sufficient voltage or current for the Broadcom substitute. Circuit redesign or driver adjustment is necessary.

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

A: Footprint dimensions are identical (3.20 x 2.80mm). Maximum height differs slightly (2.11mm Dialight vs. 2.10mm Broadcom), which is negligible for PCB assembly. Lens diameter differs (2.41mm Dialight vs. 2.20mm Broadcom); verify optical performance requirements in the application.

Q: Do both parts meet the same regulatory requirements?

A: Both parts are ROHS3 compliant and REACH unaffected. Moisture sensitivity levels differ: Dialight MSL 2 (1 Year) versus Broadcom MSL 2A (4 Weeks). Storage and handling procedures must align with the more restrictive MSL 2A specification when using the Broadcom part.

Q: What is the optical difference between the two parts?

A: Both parts emit green light with dominant wavelengths within 1nm (570nm Dialight vs. 569nm Broadcom). Peak wavelengths differ slightly (572nm vs. 565nm). Viewing angle is identical at 120°. Millicandela rating is higher for the Broadcom part (8mcd vs. 6.28mcd), providing increased brightness.

Q: Are both parts available in the same packaging formats?

A: Dialight 5973308202F is supplied in Strip packaging. Broadcom HSMG-A100-H01J1 is available in Cut Tape (CT) and Digi-Reel® packaging. Packaging format differences do not affect component compatibility but may influence procurement and assembly workflows.
