HSDL-4220 Equivalent & Substitute Parts

Part Overview

The HSDL-4220 is an Infrared (IR) Emitter manufactured by Lite-On Inc., designed for applications requiring 875nm wavelength emission at 100mA maximum forward current. This Active product operates across a 0°C to 70°C temperature range in a T 1 3/4 through-hole package. Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the specified parameter tolerances for the application.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HSDL-4220 are identified based on the following criteria:

Primary Compatibility Parameters:

• Type: Infrared (IR) Emitter
• Current - DC Forward (If) Max: 100mA
• Mounting Type: Through Hole
• RoHS Status: ROHS3 Compliant
• Product Status: Active

Secondary Consideration Parameters:

• Wavelength: 875nm (primary specification; substitutes may operate at adjacent wavelengths such as 940nm depending on application tolerance)
• Package / Case: T 1 3/4 or Radial configurations
• Viewing Angle: 30° or wider
• Voltage - Forward (Vf): Within operational circuit design margins
• Operating Temperature Range: Must encompass or exceed the application requirement

The two identified substitutes (IR333C/H0/L10 and SIR-563ST3FN) maintain the 100mA maximum forward current specification and through-hole mounting configuration. Both are Active products with ROHS3 compliance. Wavelength differences (940nm vs. 875nm) and package variations (Radial vs. T 1 3/4) represent the primary technical distinctions requiring application-level evaluation.

Parameter Comparison

Engineering Selection Recommendations

HSDL-4220 (Primary Part): Remains the specified component for applications requiring 875nm wavelength emission with 22mW/sr radiant intensity at 50mA. All compliance certifications (ROHS3, REACH Unaffected, EAR99) are current. Inventory availability is confirmed at 2692 units.

SIR-563ST3FN (Preferred Substitute): Maintains identical T 1 3/4 package configuration and 30° viewing angle. Forward voltage (1.34V) and operating temperature range (-25°C ~ 85°C) are compatible with most circuit designs. Wavelength shift to 940nm requires application verification. Inventory: 2852 units.

IR333C/H0/L10 (Alternative Substitute): Offers extended operating temperature range (-40°C ~ 85°C) and wider viewing angle (40°). Package configuration is Radial, requiring PCB layout modification. Wavelength is 940nm. Inventory: 91163 units.

All three parts maintain ROHS3 compliance and Active product status. Selection between substitutes depends on package compatibility, wavelength tolerance, and thermal operating requirements of the target application.

Frequently Asked Questions (FAQ)

Q: Can IR333C/H0/L10 replace HSDL-4220 in existing PCB designs? A: IR333C/H0/L10 uses a Radial package versus the T 1 3/4 package of HSDL-4220. PCB footprint modification is required. Wavelength differs (940nm vs. 875nm), requiring application-level compatibility verification.

Q: What is the primary difference between the two substitute parts? A: SIR-563ST3FN maintains the T 1 3/4 package and 30° viewing angle of the original part. IR333C/H0/L10 uses a Radial package with a 40° viewing angle. Both operate at 940nm wavelength.

Q: Are all three parts RoHS compliant? A: Yes. HSDL-4220, IR333C/H0/L10, and SIR-563ST3FN are all ROHS3 Compliant.

Q: Does wavelength substitution affect circuit performance? A: Wavelength differences between 875nm and 940nm may impact detector sensitivity and application performance. Application-specific testing is necessary to confirm functional equivalence.

Q: What is the temperature operating range difference? A: HSDL-4220 operates 0°C ~ 70°C. SIR-563ST3FN operates -25°C ~ 85°C. IR333C/H0/L10 operates -40°C ~ 85°C. Selection depends on thermal requirements of the application environment.

Q: Are forward voltage differences significant? A: HSDL-4220 (1.5V), SIR-563ST3FN (1.34V), and IR333C/H0/L10 (1.2V) show minor variations. Circuit design margins typically accommodate these differences, but power supply and current-limiting resistor values should be verified for the selected substitute.
