All identified substitute parts meet these parameters without exception. Variations in manufacturer series designation or packaging configuration do not affect electrical or mechanical interchangeability.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts—Dialight 5611301100F and Dialight 5501304F—are qualified replacements for the 5611301070F based on complete electrical and mechanical parameter alignment. All three parts maintain active production status and carry identical RoHS3 and REACH compliance certifications. The 5611301100F remains within the same 561 series as the original part, while the 5501304F represents an alternative series designation from the same manufacturer. Selection between these options may be based on inventory availability or supply chain considerations, as all three parts deliver identical performance characteristics in circuit board indicator applications.

Frequently Asked Questions (FAQ)

Q: Can the 5611301100F and 5501304F be used interchangeably with the 5611301070F?

A: Yes. All three parts share identical electrical specifications (1.8V, 2mA, 1.8mcd), optical properties (565nm peak wavelength, 50° viewing angle, diffused green lens), and mechanical form factors (5mm T-1 3/4 through-hole mount). Direct substitution requires no circuit modifications.

Q: What determines whether a part qualifies as a substitute?

A: Substitute qualification requires exact matching of color, wavelength, current rating, voltage rating, luminous intensity, viewing angle, lens type and style, physical dimensions, mounting type, and compliance certifications. Any deviation in these parameters disqualifies a part from substitution status.

Q: Are there differences in packaging between these parts?

A: All three parts are supplied in bulk packaging. Packaging configuration does not affect electrical or mechanical performance.

Q: Do all substitute parts carry the same compliance certifications?

A: Yes. The 5611301070F, 5611301100F, and 5501304F all maintain ROHS3 compliance, REACH unaffected status, and MSL 1 (unlimited) moisture sensitivity rating.

Q: What is the significance of the series designation difference between 561 and 550?

A: Series designation reflects manufacturer product line organization but does not indicate functional differences when all electrical and mechanical parameters are identical. Both series parts meet the same performance requirements for this application.
