Substitute Part Grouping Explanation

Substitution eligibility for the ASDL-4263-C22 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Wavelength: 940nm (exact match required)
• Mounting Type: Through Hole Radial (mechanical compatibility)
• Forward Voltage (Vf): 1.2V (circuit compatibility)
• Operating Temperature Range: Must encompass or exceed -40°C ~ 85°C

Secondary Compatibility Criteria:

• Maximum Forward Current (If): Substitute must support at least 50mA operation
• Radiant Intensity: Substitute performance at specified current levels
• Viewing Angle: Optical field considerations for application requirements

The EAILP05RDDA8 qualifies as a manufacturer-recommended substitute based on matching wavelength (940nm), forward voltage (1.2V), mounting configuration (Through Hole Radial), and exceeding the current rating requirement (100mA vs. 50mA). The substitute maintains operational compatibility within the specified temperature range, though with a narrower lower bound (-25°C vs. -40°C).

Parameter Comparison

Engineering Selection Recommendations

The EAILP05RDDA8 is the manufacturer-recommended substitute for the obsolete ASDL-4263-C22. Selection of this alternative is supported by:

Product Status: The EAILP05RDDA8 maintains Active product status, ensuring continued availability and manufacturing support, whereas the ASDL-4263-C22 is Obsolete.

Regulatory Compliance: The EAILP05RDDA8 carries ROHS3 Compliant certification, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.

Electrical Compatibility: Both components operate at identical forward voltage (1.2V) and wavelength (940nm), ensuring direct circuit compatibility. The substitute's higher maximum forward current rating (100mA) provides operational margin above the original specification (50mA).

Mechanical Compatibility: Both components utilize identical Through Hole Radial mounting configuration, permitting direct PCB footprint compatibility without layout modification.

Temperature Consideration: The substitute's operating temperature range (-25°C ~ 85°C) covers the upper portion of the original range. Applications requiring operation below -25°C require thermal analysis or alternative component selection.

Frequently Asked Questions (FAQ)

Q: Can the EAILP05RDDA8 directly replace the ASDL-4263-C22 in existing designs?

A: Yes, for applications operating within -25°C to 85°C. Both components share identical forward voltage (1.2V), wavelength (940nm), and radial through-hole mounting. Direct PCB substitution is mechanically and electrically compatible. Applications requiring operation below -25°C require design review.

Q: What are the key differences between these components?

A: The primary differences are: (1) Maximum forward current: EAILP05RDDA8 supports 100mA versus ASDL-4263-C22 at 50mA; (2) Viewing angle: EAILP05RDDA8 provides 40° versus 20° for the original; (3) Radiant intensity: ASDL-4263-C22 delivers 9.72mW/sr @ 20mA versus 7.8mW/sr @ 20mA for EAILP05RDDA8; (4) Operating temperature lower bound: EAILP05RDDA8 minimum is -25°C versus -40°C for the original.

Q: Are there packaging or mounting differences?

A: No. Both components use identical Through Hole Radial packaging and mounting configuration. No PCB layout or mechanical modifications are required for substitution.

Q: What compliance certifications apply to the substitute?

A: The EAILP05RDDA8 is ROHS3 Compliant, meeting current environmental regulations for electronic components. Both components carry EAR99 export classification and HTSUS code 8541.41.0000.

Q: How does the wider viewing angle of the substitute affect circuit performance?

A: The EAILP05RDDA8 provides a 40° viewing angle compared to the original 20°. This wider angle increases the optical field of view, which may affect proximity sensing accuracy or IR communication range depending on application design. Circuit performance requires evaluation based on specific optical and detection requirements.

Q: Is the lower radiant intensity of the substitute a concern?

A: The EAILP05RDDA8 delivers 7.8mW/sr @ 20mA versus 9.72mW/sr @ 20mA for the original. The substitute's higher maximum current rating (100mA) permits operation at higher drive levels to compensate for intensity differences if required by the application.
