Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 5912501002F is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Voltage Rating: 2V (exact match required)
• Configuration: Single (exact match required)
• Mounting Type: Surface Mount, Right Angle (exact match required)
• Color: Orange (exact match required)
• Series: 591 (same manufacturer family)

Allowable Variation Parameters:

• Current: 10mA (baseline); substitutes may operate at different current ratings if circuit design accommodates
• Millicandela Rating: 13.7mcd (baseline); substitutes with higher brightness are acceptable if optical requirements permit
• Lens Size: 5.10mm Dia (baseline); substitutes with different lens dimensions require mechanical fit verification
• Lens Style: Round with Flat Top (baseline); substitutes with alternative lens geometry require optical and mechanical assessment
• Wavelength - Peak: 606nm (baseline); substitutes within orange spectrum range are acceptable

The identified substitute 5912501002NF maintains all mandatory compatibility criteria while introducing variations in current, brightness, lens size, and lens style that require design-level evaluation.

Parameter Comparison

Engineering Selection Recommendations

The 5912501002NF qualifies as a functional substitute based on shared electrical specifications (2V voltage rating, single configuration) and identical mounting architecture (Surface Mount, Right Angle). Both components maintain ROHS3 compliance and equivalent moisture sensitivity ratings.

Key differences requiring design consideration:

Current Increase: The substitute operates at 20mA versus the original 10mA. Circuit current-limiting resistor values must be recalculated to maintain proper LED operation and prevent overstress.

Brightness Increase: The substitute delivers 83mcd compared to 13.7mcd. Applications requiring specific illumination levels must verify that increased brightness remains acceptable for the intended function.

Lens Geometry Change: The substitute features a 2.85mm diameter domed lens versus the original 5.10mm flat-top lens. Mechanical fit within the PCB assembly and optical viewing characteristics require verification against design constraints.

Wavelength Shift: The substitute operates at 610nm versus 606nm. This 4nm shift remains within the orange spectrum and is typically imperceptible to human vision but should be confirmed if color matching is critical.

Product Status: The substitute is Active, ensuring continued availability and supply chain stability compared to the Obsolete status of the original part.

Frequently Asked Questions (FAQ)

Q: Can the 5912501002NF be used as a direct drop-in replacement for the 5912501002F?

A: Electrical compatibility is confirmed (2V, single configuration, Surface Mount Right Angle). However, the increased current (20mA vs. 10mA), higher brightness (83mcd vs. 13.7mcd), smaller lens diameter (2.85mm vs. 5.10mm), and different lens style (domed vs. flat top) require circuit and mechanical validation before implementation.

Q: What circuit modifications are necessary when substituting to the 5912501002NF?

A: The current-limiting resistor must be recalculated for 20mA operation. The resistor value will be approximately half that of the original design. No other circuit modifications are required if the 2V supply voltage remains unchanged.

Q: Will the smaller lens size (2.85mm vs. 5.10mm) affect PCB layout?

A: Yes. The substitute has a significantly smaller footprint. PCB mounting hole spacing and clearance requirements must be verified against the substitute component's mechanical specifications. Physical fit validation is mandatory before production implementation.

Q: Is the wavelength difference (610nm vs. 606nm) visually noticeable?

A: The 4nm shift remains within the orange spectrum range. Human perception of this wavelength difference is negligible under typical viewing conditions. However, if the application requires precise color matching or spectral consistency, this parameter should be confirmed as acceptable.

Q: Are both parts equally compliant with environmental and regulatory standards?

A: Yes. Both components are ROHS3 compliant, REACH unaffected, and carry identical MSL ratings (2, 1 Year). Regulatory and environmental compatibility is confirmed.

Q: What is the inventory status for each part?

A: The original 5912501002F (Obsolete) has 805 pcs in stock. The substitute 5912501002NF (Active) has 737 pcs in stock. The Active status of the substitute ensures long-term availability.
