74F826AP-RC Equivalent & Substitute Parts

Part Overview

The 74F826AP-RC is an 8.2 µH unshielded wirewound inductor manufactured by Bourns Inc., designed for through-hole axial mounting applications. This component is rated for 275 mA maximum current with a DC resistance of 1.9 Ohm maximum and operates across a temperature range of -55°C to 125°C. The product is currently obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 74F826AP-RC is determined by the following critical parameters:

• Inductance Value: Must be 8.2 µH with ±10% tolerance to maintain circuit performance
• Mounting Configuration: Through-hole axial package required for mechanical compatibility
• Shielding Type: Unshielded specification must be maintained
• Operating Temperature Range: Must support -55°C to 125°C minimum
• RoHS Compliance: ROHS3 compliance required for regulatory alignment

The 1945R-07K from API Delevan Inc. meets these core substitution criteria. While this substitute exhibits different construction (molded vs. wirewound), different core material (iron vs. phenolic), and different DC resistance (560 mOhm vs. 1.9 Ohm), it maintains the same inductance value, tolerance, mounting type, package configuration, temperature range, and regulatory compliance status.

Parameter Comparison

Engineering Selection Recommendations

The 1945R-07K serves as a direct functional substitute for the obsolete 74F826AP-RC based on matching inductance specifications, tolerance, mounting configuration, and regulatory compliance. Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment in new designs and legacy system support.

The 1945R-07K offers improved current handling capability (720 mA vs. 275 mA) and significantly lower DC resistance (560 mOhm vs. 1.9 Ohm), which may provide thermal and efficiency advantages in applications where the original 275 mA rating was marginal. The substitute's active product status ensures ongoing availability and supply chain continuity compared to the obsolete 74F826AP-RC.

Physical dimensions differ slightly (0.193" Dia x 0.447" L for 1945R-07K vs. 0.200" Dia x 0.500" L for 74F826AP-RC), requiring verification of board layout constraints in space-critical applications.

Frequently Asked Questions (FAQ)

Q: Can the 1945R-07K directly replace the 74F826AP-RC in existing designs?

A: Yes, for applications where the 275 mA current rating of the original component was not fully utilized. The matching 8.2 µH inductance, ±10% tolerance, unshielded configuration, and through-hole axial package ensure functional compatibility. Physical dimensions should be verified for PCB layout constraints.

Q: What are the key differences between these two inductors?

A: The primary differences are construction type (wirewound vs. molded), core material (phenolic vs. iron), DC resistance (1.9 Ohm vs. 560 mOhm), and current rating (275 mA vs. 720 mA). The 1945R-07K exhibits lower losses and higher current capacity, while the 74F826AP-RC provides higher impedance characteristics.

Q: Are both components RoHS compliant?

A: Yes, both the 74F826AP-RC and 1945R-07K are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement.

Q: What is the impact of different DC resistance values?

A: The 1945R-07K's lower DC resistance (560 mOhm) results in reduced power dissipation and heat generation compared to the 74F826AP-RC (1.9 Ohm). This difference is significant in high-frequency or continuous-current applications and should be evaluated against circuit design requirements.

Q: Are there packaging differences between these components?

A: Both components use through-hole axial packaging. However, physical dimensions differ slightly: the 1945R-07K measures 0.193" Dia x 0.447" L, while the 74F826AP-RC measures 0.200" Dia x 0.500" L. Board layout verification is recommended for space-constrained designs.
