Parameter Comparison

Engineering Selection Recommendations

The SSF-LXH103LID serves as a direct substitute for the obsolete 5650F1LC based on the following engineering criteria:

Compliance and Regulatory Alignment: Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory continuity in applications subject to environmental restrictions. Moisture sensitivity level 1 (unlimited) is identical across both parts, eliminating moisture handling and storage requirement changes.

Physical and Optical Compatibility: Identical 3mm T-1 form factor, round domed lens style, and right-angle through-hole mounting ensure mechanical fit within existing PCB designs without layout modifications. Matching red color and 635nm peak wavelength preserve optical performance characteristics.

Electrical Performance: The SSF-LXH103LID operates at 2V with a 20mA maximum current rating, compared to the 5650F1LC at 1.8V with 2mA. This specification difference allows the substitute to function in circuits designed for the original part. Circuit designers must verify that existing current-limiting resistor values accommodate the higher voltage and current ratings of the substitute to prevent over-driving the LED.

Product Status: The SSF-LXH103LID is active production status, ensuring long-term availability and supply chain stability compared to the obsolete 5650F1LC.

Frequently Asked Questions (FAQ)

Q: Can the SSF-LXH103LID directly replace the 5650F1LC without circuit modifications?

A: Physical and optical compatibility is direct. However, electrical circuit verification is required. The substitute operates at 2V versus 1.8V and supports 20mA versus 2mA. Existing current-limiting resistors must be recalculated to prevent LED over-current. The substitute will function in the original circuit if the resistor value limits current appropriately for the 2V rating.

Q: Are the lens optical properties identical between these two parts?

A: Yes. Both components feature diffused, tinted lens types with round domed top styling in 3mm T-1 form factor. Peak wavelength is 635nm for both parts, ensuring color consistency. The SSF-LXH103LID delivers higher luminous intensity (40mcd versus 2.5mcd) due to increased current capacity.

Q: What is the impact of the voltage rating difference (1.8V versus 2V)?

A: The 0.2V difference reflects the electrical characteristics of the substitute LED die. In circuit applications, the voltage drop across the LED is determined by the forward voltage of the specific LED die. Circuit designers must account for this difference when calculating series resistor values to maintain proper current limiting.

Q: Are storage and handling requirements different between these parts?

A: No. Both components have identical moisture sensitivity level 1 (unlimited), indicating no special moisture control requirements during storage or handling. Standard ESD precautions apply to both parts.

Q: Can the SSF-LXH103LID be used in low-power applications requiring exactly 2mA operation?

A: The SSF-LXH103LID is rated for 20mA maximum current. In applications requiring 2mA operation, the substitute can be used by selecting an appropriate series resistor value to limit current to 2mA. The LED will operate safely at this reduced current level.

Q: What packaging format is available for the SSF-LXH103LID?

A: The SSF-LXH103LID is supplied in bulk packaging. Inventory availability is 28,230 pieces in new original stock condition.
