Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 5912401002F are identified based on the following critical parameters that determine functional equivalence:

Primary Matching Criteria:

• Color: Yellow
• Configuration: Single LED
• Mounting Type: Surface Mount, Right Angle
• Voltage Rating: Compatible with 2V operation (2V to 2.1V acceptable range)
• Lens Type: Diffused or Diffused/Tinted
• RoHS Compliance: ROHS3 Compliant

Secondary Considerations:

• Current Rating: 10mA to 20mA range
• Millicandela Rating: 5.7mcd to 71mcd range
• Viewing Angle: 40° to 60° range
• Wavelength Peak: 585nm to 591nm range (yellow spectrum)

The two identified substitutes meet these criteria while maintaining compatibility with the original design intent and regulatory requirements.

Parameter Comparison

Engineering Selection Recommendations

5912401002NF (Dialight) is the primary substitute option. This part maintains manufacturer continuity with Dialight and shares identical voltage and viewing angle specifications. The increased current rating (20mA vs. 10mA) and higher luminous intensity (71mcd vs. 5.7mcd) require circuit-level current limiting adjustments but provide enhanced brightness margin. Active product status ensures long-term availability and supply chain stability. ROHS3 compliance and MSL 2 rating match the original specification.

SSF-LXH305YD-TR (Lumex Opto/Components Inc.) serves as a secondary substitute when Dialight parts are unavailable. This part introduces a cross-manufacturer option with compatible yellow wavelength and diffused lens characteristics. The 60° viewing angle provides wider light distribution compared to the 40° original specification. Voltage rating of 2.1V remains within acceptable tolerance for 2V circuit designs. MSL 1 rating offers superior moisture protection for extended storage. Active product status and ROHS3 compliance confirm regulatory alignment.

Both substitutes maintain Surface Mount, Right Angle mounting compatibility and yellow color specification. Selection between substitutes depends on brightness requirements, viewing angle tolerance, and supply chain preferences.

Frequently Asked Questions (FAQ)

Q: Can the 5912401002NF directly replace the 5912401002F without circuit modifications?

A: The 5912401002NF operates at identical voltage (2V) and viewing angle (40°), enabling direct mechanical substitution. However, the increased current rating (20mA vs. 10mA) and luminous intensity (71mcd vs. 5.7mcd) require circuit-level current limiting adjustments to prevent component overstress. Existing current-limiting resistors must be recalculated for the higher current specification.

Q: What are the key differences between the two substitute options?

A: The 5912401002NF maintains Dialight manufacturer continuity with identical voltage and viewing angle. The SSF-LXH305YD-TR introduces a cross-manufacturer alternative with a wider 60° viewing angle and superior MSL 1 moisture rating. Both parts share yellow color, diffused lens characteristics, and ROHS3 compliance. Luminous intensity differs: 71mcd (5912401002NF) versus 30mcd (SSF-LXH305YD-TR).

Q: Are there packaging considerations when selecting a substitute?

A: Yes. The 5912401002NF is supplied in Strip packaging, while the SSF-LXH305YD-TR uses Tape & Reel (TR) format. Tape & Reel packaging is standard for automated assembly processes and offers better handling for high-volume production. Strip packaging may require manual handling or custom feeder adaptation.

Q: Does the 2.1V rating of the SSF-LXH305YD-TR create compatibility issues with 2V circuits?

A: No. The 2.1V rating represents the forward voltage specification and remains compatible with 2V circuit designs. Standard current-limiting resistor calculations accommodate this minor voltage differential without circuit redesign.

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

A: The 5912401002NF carries MSL 2 (1 Year), requiring controlled storage conditions and limiting shelf life. The SSF-LXH305YD-TR carries MSL 1 (Unlimited), eliminating moisture sensitivity constraints and enabling indefinite storage without special handling. MSL 1 rating provides supply chain flexibility for long-term inventory management.

Q: Are all three parts ROHS3 compliant?

A: Yes. The 5912401002F (main part), 5912401002NF, and SSF-LXH305YD-TR all carry ROHS3 Compliant status, confirming regulatory alignment with current manufacturing standards and environmental directives.
