Substitute Part Grouping Explanation

The Dialight 5912101013NF qualifies as a substitute for the 5912101013F based on the following alignment of critical electrical and mechanical parameters:

Matching Parameters:

• Manufacturer: Dialight (same manufacturer, same product series 591)
• Color: Red
• Configuration: Single LED
• Current Rating: 20mA (identical)
• Viewing Angle: 40° (identical)
• Lens Style: Round with Domed Top (identical)
• Mounting Type: Surface Mount, Right Angle (identical)
• RoHS Status: ROHS3 Compliant (identical)
• MSL Rating: 2 (1 Year) (identical)

Allowable Variations:

• Voltage Rating: 1.8V (main part) vs. 1.85V (substitute) — within acceptable tolerance for LED forward voltage specifications
• Wavelength - Peak: 660nm (main part) vs. 655nm (substitute) — both within red spectrum range
• Millicandela Rating: 18mcd (main part) vs. 34mcd (substitute) — substitute provides higher brightness output
• Lens Size: 3mm (main part) vs. 2.85mm (substitute) — minor dimensional variation
• Product Status: Obsolete (main part) vs. Active (substitute) — substitute is currently in production

Parameter Comparison

Engineering Selection Recommendations

The Dialight 5912101013NF is suitable as a substitute for the obsolete 5912101013F in applications requiring a red Surface Mount, Right Angle LED Circuit Board Indicator with 20mA current operation. Both parts maintain identical compliance certifications (ROHS3 Compliant, REACH Unaffected) and identical moisture sensitivity levels, ensuring equivalent reliability in storage and handling.

The substitute part is currently in Active production status, providing supply chain continuity for new designs and replacement inventory. The forward voltage differential (1.8V to 1.85V) falls within standard LED tolerance ranges and presents no compatibility issues in typical circuit implementations. The increased brightness output (34mcd vs. 18mcd) represents an enhancement that does not compromise circuit functionality.

Frequently Asked Questions (FAQ)

Q: Can the 5912101013NF directly replace the 5912101013F in existing designs?

A: Yes. Both parts share identical current ratings (20mA), viewing angles (40°), mounting configurations (Surface Mount, Right Angle), and lens styles (Round with Domed Top). The forward voltage difference (0.05V) and wavelength variation (5nm) are within acceptable operating tolerances for LED circuit board indicators.

Q: What is the significance of the product status change from Obsolete to Active?

A: The 5912101013NF is currently manufactured and available through standard distribution channels, whereas the 5912101013F is no longer in production. This ensures long-term supply availability for new production runs and maintenance stock replenishment.

Q: Are there packaging differences between these parts?

A: The 5912101013F is supplied in standard packaging, while the 5912101013NF is supplied in Tape & Reel (TR) format. Tape & Reel packaging is standard for automated assembly processes and does not affect component performance or electrical characteristics.

Q: Does the higher brightness rating of the substitute part affect circuit design?

A: No. The 5912101013NF operates at the same 20mA current rating as the original part. The increased millicandela output (34mcd vs. 18mcd) results from improved LED die efficiency and does not require circuit modifications. Current-limiting resistor values remain unchanged.

Q: Are both parts compliant with the same regulatory standards?

A: Yes. Both the 5912101013F and 5912101013NF are ROHS3 Compliant, REACH Unaffected, and carry identical Moisture Sensitivity Level ratings (MSL 2, 1 Year). They meet the same environmental and regulatory requirements for electronic component use.
