Substitute Part Grouping Explanation
Substitution eligibility for the 5640100121F is determined by the following critical parameters: manufacturer (Dialight), series (564), lens size (3mm T-1), mounting type (through-hole right-angle), current rating (30mA), voltage rating (2.1V Green / 2V Red), and viewing angle (60°). Parts meeting these specifications are classified as direct substitutes. Parts with identical electrical and mechanical parameters but different color configurations are classified as similar substitutes, provided the application can accommodate the alternative LED color arrangement.
Direct Substitute: 5640100112F matches all electrical and mechanical parameters identically.
Similar Substitute: 5640700101F maintains compatible electrical specifications and mounting but features a different color configuration (Green, Red x2, Blank x1) and belongs to a different base product series (5640700 vs 5640100).

Engineering Selection Recommendations
5640100112F is a direct functional equivalent to 5640100121F. Both parts maintain identical electrical characteristics, mechanical form factor, and compliance certifications. Selection between these two part numbers should be based on inventory availability and procurement lead times, as no technical differentiation exists.
5640700101F is suitable as a substitute only when the application design can accommodate a different LED color arrangement. This part includes one blank position instead of a second red LED, resulting in a Green-Red-Blank configuration. The electrical parameters remain compatible with the main part. The different base product series designation (5640700 vs 5640100) reflects the color configuration change but does not affect electrical or mechanical compatibility within the specified parameters.
All three parts maintain ROHS3 compliance, MSL Level 1 rating, and REACH unaffected status, ensuring regulatory compatibility in current production environments.
Frequently Asked Questions (FAQ)
Q: Can 5640100112F be used as a direct replacement for 5640100121F?
A: Yes. Both parts are identical in all electrical and mechanical specifications, including current rating, voltage rating, lens size, mounting type, and viewing angle. No design modifications are required.
Q: What is the key difference between 5640100121F and 5640700101F?
A: The primary difference is the LED color configuration. The 5640100121F provides Green-Red-Red, while the 5640700101F provides Green-Red-Blank. Both maintain the same electrical parameters (30mA current, 2.1V Green / 2V Red voltage) and 3mm T-1 through-hole right-angle mounting. Substitution is valid only if the application circuit can function with the blank position.
Q: Are all three parts RoHS and REACH compliant?
A: Yes. All three parts (5640100121F, 5640100112F, and 5640700101F) are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.
Q: Does the different base product series number (5640100 vs 5640700) affect compatibility?
A: No. The series designation reflects the color configuration variant within the Dialight 564 family. Electrical and mechanical compatibility is determined by the parameters listed in this document, not the series number alone.
Q: What is the MSL rating for these parts?
A: All three parts carry MSL Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
