Engineering Selection Recommendations

5972211607F (Dialight) - Primary Substitute for Orange Wavelength Applications

The 5972211607F is an active product with identical mechanical specifications and matching 605nm dominant wavelength. Forward voltage increases from 1.9V to 2V, which is within acceptable tolerance for most indication circuits. Brightness increases to 125mcd, providing enhanced visibility. This part carries ROHS3 compliance and improved moisture sensitivity rating (MSL 3 vs. MSL 4), supporting modern manufacturing and environmental standards. The 5972211607F is suitable for direct replacement in applications where orange indication at 605nm is required.

APA3010SYCK (Kingbright) - Alternative for Yellow Wavelength Applications

The APA3010SYCK is an active product with identical mechanical specifications but operates at 590nm dominant wavelength (yellow spectrum). This part is suitable only for applications where yellow indication is functionally acceptable as a visual alternative to orange. Forward voltage is 2V with 150mcd brightness. ROHS3 compliance and MSL 3 rating are present. Selection of this part requires confirmation that yellow wavelength substitution does not compromise application requirements or user interface consistency.

Both substitute parts are active products with current manufacturing support, ensuring long-term availability compared to the obsolete FA1101F-TR.

Frequently Asked Questions (FAQ)

Q: Can the 5972211607F directly replace the FA1101F-TR in existing PCB designs?

A: Yes. The 5972211607F matches all mechanical parameters: 3.00mm L x 2.00mm W footprint, 1.00mm maximum height, 2-SMD no-lead package, right-angle surface mount configuration, and identical lens dimensions (2.00mm x 1.00mm). Forward voltage increases from 1.9V to 2V, which is compatible with standard indication circuit designs. Wavelength remains at 605nm (orange).

Q: What is the difference between the 5972211607F and APA3010SYCK?

A: Both parts share identical mechanical specifications and mounting characteristics. The primary difference is wavelength: 5972211607F operates at 605nm (orange), while APA3010SYCK operates at 590nm (yellow). The APA3010SYCK is suitable only if yellow indication is functionally equivalent to orange in the application. Brightness also differs: 5972211607F provides 125mcd versus 150mcd for APA3010SYCK.

Q: Does the forward voltage difference between FA1101F-TR (1.9V) and substitute parts (2V) affect circuit design?

A: The 0.1V increase is within standard tolerance for indication LED circuits. Most designs using series current-limiting resistors accommodate this variation without modification. Circuit designers should verify that the 2V forward voltage remains within the operating range of the driving circuit.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both 5972211607F and APA3010SYCK are ROHS3 compliant. The original FA1101F-TR RoHS status was not specified in available documentation.

Q: What is the significance of the MSL rating difference?

A: The FA1101F-TR carries MSL 4 (72 hours), while both substitutes carry MSL 3 (168 hours). MSL 3 provides extended moisture protection and is preferred for modern manufacturing environments. Lower MSL ratings indicate better moisture resistance and longer shelf life after packaging.

Q: Can I use the APA3010SYCK as a direct replacement for the FA1101F-TR?

A: Mechanically and electrically, yes. However, the APA3010SYCK produces yellow indication (590nm) instead of orange (605nm). This substitution is valid only if the application does not require specific orange wavelength for user interface consistency, safety compliance, or color-coded indication schemes.

Q: What inventory status should I consider when selecting a substitute?

A: The 5972211607F has 708 units in stock, and APA3010SYCK has 2460 units in stock. Both are active products with ongoing manufacturing support, ensuring continued availability. The original FA1101F-TR is obsolete with 1029 units remaining in inventory.
