Two substitute parts meet these criteria and are listed below.

Parameter Comparison

Engineering Selection Recommendations

Dialight 5912401113NF is the primary substitute for the 5912401113F. Both parts are manufactured by Dialight within the same 591 series, share identical mounting configurations, and maintain ROHS3 compliance with matching MSL ratings. The 5912401113NF operates at the same 2V voltage rating and 40° viewing angle. The lens size reduction from 3mm to 2.85mm requires verification of circuit board layout compatibility. The increased current rating (20mA vs. 10mA) and brightness output (71mcd vs. 12.6mcd) provide enhanced performance margins within the same form factor.

Lumex Opto/Components Inc. SSF-LXH305YD-TR serves as a secondary substitute. This part maintains the 3mm lens size and diffused lens type, eliminating layout concerns. The voltage rating of 2.1V is within acceptable tolerance for 2V-rated circuits. The 60° viewing angle provides wider light distribution compared to the original 40° specification. The MSL rating of 1 (Unlimited) offers superior moisture protection. The 20mA current and 30mcd brightness represent intermediate performance between the original and the Dialight substitute.

Both substitutes are Active products with confirmed inventory availability and full RoHS3 compliance, supporting long-term supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the 5912401113NF be used as a direct replacement for the 5912401113F?

A: The 5912401113NF is functionally equivalent for most applications. The primary consideration is the lens size reduction from 3mm to 2.85mm. Verify that the circuit board mounting hole and surrounding component layout accommodate the smaller diameter. Both parts share identical voltage, mounting type, and viewing angle specifications.

Q: What is the impact of the voltage difference between the main part (2V) and the Lumex substitute (2.1V)?

A: The 0.1V difference is within standard circuit tolerance for LED indicator applications. The Lumex SSF-LXH305YD-TR operates at 2.1V, which is compatible with 2V-rated circuits. Verify that the power supply or current-limiting resistor design accommodates this minor voltage variation.

Q: How do the brightness differences affect circuit performance?

A: The main part delivers 12.6mcd at 10mA. The Dialight substitute provides 71mcd at 20mA, and the Lumex substitute provides 30mcd at 20mA. Higher brightness may require circuit-level current limiting adjustments to prevent over-driving the LED. Lower brightness is not a concern for indicator applications where the original brightness was adequate.

Q: Are there packaging considerations when switching between these parts?

A: The main part uses standard packaging (not specified). Both substitutes are supplied in Tape & Reel (TR) format, which is standard for surface mount production. Verify that your assembly equipment and processes support TR packaging.

Q: Do the MSL ratings affect storage and handling?

A: The main part and Dialight substitute both carry MSL 2 (1 Year), requiring controlled storage conditions. The Lumex substitute carries MSL 1 (Unlimited), offering more flexible storage without time-based constraints. For high-volume production with extended inventory holding periods, the Lumex part provides logistical advantages.

Q: Can both substitutes be used interchangeably in the same design?

A: Both substitutes meet the core compatibility criteria but differ in lens size, brightness, and MSL rating. Select one substitute based on your specific circuit board layout constraints and brightness requirements. Do not mix parts within a single production batch unless the design explicitly accommodates both specifications.
