WP63ID (Kingbright): This part operates at 2V forward voltage with 20mA test current, matching the LTL-5223 voltage specification. It provides 12mcd brightness with 60° viewing angle and 6.00mm height. Peak wavelength is 627nm, within the red spectrum range.

Frequently Asked Questions (FAQ)

Q: Can HLMP-3351 series parts directly replace LTL-5223 in existing designs?

A: HLMP-3351 series parts are electrically compatible at 1.9V forward voltage versus the LTL-5223 at 2V. Circuit designs with fixed current-limiting resistors will operate at slightly different brightness levels. Mechanical compatibility is confirmed for 5mm through-hole radial mounting. Verify brightness requirements for your specific application.

Q: What is the difference between HLMP-3351-D0000 and HLMP-3351-D0002?

A: Both parts are electrically and mechanically identical. The primary difference is packaging: HLMP-3351-D0000 is supplied in Bulk packaging, while HLMP-3351-D0002 is supplied in Cut Tape (CT) format. Select based on assembly process requirements.

Q: Why does SSL-LX5063ID have a higher millicandela rating than LTL-5223?

A: SSL-LX5063ID is rated at 40mcd versus LTL-5223 at 5.6mcd. This difference reflects the part's design for higher luminous intensity applications. Both parts maintain diffused lens characteristics and red color specification. Select based on required brightness for your indication circuit.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts—HLMP-3351, HLMP-3351-D0000, HLMP-3351-D0002, SSL-LX5063ID, and WP63ID—are RoHS3 compliant and maintain Active product status, meeting regulatory requirements equivalent to the LTL-5223.

Q: What viewing angle differences exist among substitute parts?

A: LTL-5223 provides 64° viewing angle. HLMP-3351 series parts provide 50° viewing angle. SSL-LX5063ID and WP63ID provide 60° viewing angle. Narrower viewing angles concentrate light intensity in the forward direction; wider angles distribute light across a broader field. Select based on circuit board layout and visibility requirements.

Q: Can WP63ID replace LTL-5223 in brightness-critical applications?

A: WP63ID is rated at 12mcd versus LTL-5223 at 5.6mcd, providing approximately 2.1x higher brightness. Both operate at 2V forward voltage. If your application requires the original brightness level, WP63ID will produce noticeably brighter indication. Adjust circuit design if brightness reduction is necessary.
