Key Parameters

Substitute Part Grouping Explanation

Substitute component identification for the 5335H1 is based on the following critical parameters that determine functional compatibility:

Primary Substitution Criteria:

• Color: Red wavelength output (635nm to 650nm range acceptable)
• Configuration: Single LED element
• Mounting Type: Through hole PCB mounting
• Lens Type: Diffused optical characteristics
• Regulatory Compliance: ROHS3 compliance maintained
• Moisture Sensitivity: MSL 1 rating

Secondary Compatibility Factors:

• Forward current rating (35mA nominal)
• Millicandela output (30mcd minimum)
• Forward voltage (1.8V to 2.1V operating range)
• Physical form factor (5mm package envelope)

The Dialight 5505104F meets these substitution criteria as a red diffused LED with through-hole mounting, ROHS3 compliance, and MSL 1 rating. Operational parameter variations exist within acceptable engineering tolerances for circuit board indicator applications.

Engineering Selection Recommendations

For 5335H1 Replacement Applications:

The Dialight 5505104F qualifies as a functional substitute based on the following engineering criteria:

1. Product Status Alignment: The 5505104F carries active product status, ensuring continued availability and supply chain support compared to the obsolete 5335H1.

2. Regulatory Compliance: Both components maintain ROHS3 compliance and identical MSL 1 moisture sensitivity ratings, satisfying environmental and reliability requirements.

3. Optical and Electrical Compatibility: Red diffused lens configuration with through-hole mounting provides direct form-factor compatibility. Peak wavelength variation (635nm to 650nm) remains within acceptable red LED spectrum parameters for circuit board indicator applications.

4. Operating Parameter Considerations: The 5505104F operates at 20mA forward current versus the 5335H1's 35mA specification. Circuit designs must accommodate this current reduction through appropriate series resistor adjustment. The substitute delivers 34mcd brightness compared to 30mcd, providing equivalent or improved visual indication performance.

5. Voltage Rating Adjustment: Forward voltage increases from 1.8V to 2.1V. Existing circuit designs require verification that power supply and current-limiting resistor values accommodate this 0.3V differential.

Selection Conclusion: The 5505104F is suitable for direct substitution in legacy designs where circuit parameters can be adjusted for the reduced forward current and increased forward voltage specifications.

Frequently Asked Questions (FAQ)

Q: Can the Dialight 5505104F directly replace the VCC 5335H1 without circuit modification?

A: Direct pin-for-pin replacement is possible due to identical through-hole mounting configuration. However, circuit resistor values require recalculation to accommodate the 5505104F's 20mA forward current and 2.1V forward voltage specifications, which differ from the 5335H1's 35mA and 1.8V ratings.

Q: What is the wavelength difference between 635nm and 650nm, and does it affect visual appearance?

A: Both wavelengths fall within the red spectrum. The 650nm output of the 5505104F represents a slightly longer wavelength toward the orange-red region compared to the 5335H1's 635nm. For circuit board indicator applications, this difference is not visually significant to the human eye.

Q: Why does the 5505104F operate at lower current (20mA vs. 35mA)?

A: The 5505104F is designed with different LED junction characteristics and optical efficiency. Lower forward current reduces power consumption while maintaining comparable brightness output (34mcd vs. 30mcd). This represents improved energy efficiency in the substitute component.

Q: Are there viewing angle differences between these components?

A: The 5335H1 viewing angle specification is not provided in the technical data. The 5505104F specifies a 50° viewing angle. Both components feature diffused lens designs suitable for general circuit board indicator applications.

Q: Do both components meet the same environmental and compliance standards?

A: Yes. Both the 5335H1 and 5505104F are ROHS3 compliant with MSL 1 moisture sensitivity ratings. Both carry EAR99 ECCN classification and fall under the same HTSUS tariff code (8541.41.0000), indicating equivalent regulatory and trade classification status.

Q: What packaging format is the 5505104F supplied in?

A: The 5505104F is supplied in bulk packaging, compared to the 5335H1's standard packaging designation. Verify bulk quantity requirements align with procurement and inventory management procedures.
