Key Parameters

Substitute Part Grouping Explanation

Substitution of the 74F396AP-RC is determined by the following critical parameters:

• Inductance Value: Must match 3.9 µH within the specified ±10% tolerance
• Inductance Tolerance: ±10% tolerance ensures compatibility with circuit design specifications
• Shielding Type: Unshielded configuration must be maintained to preserve electromagnetic characteristics
• Mounting Type: Through-hole axial mounting is required for mechanical compatibility
• Operating Temperature Range: Must support -55°C to 125°C to meet environmental requirements
• Current Rating: Substitute must support minimum 500 mA; higher ratings are acceptable
• DC Resistance: Lower DCR values improve efficiency; higher values may impact circuit performance

The 1945R-03K from API Delevan Inc. meets these substitution criteria with equivalent inductance, tolerance, shielding, mounting type, and operating temperature range. The substitute offers improved current handling (1.2 A vs. 500 mA) and lower DC resistance (190mOhm vs. 800mOhm), making it suitable for direct replacement in the 74F396AP-RC application.

Parameter Comparison

Engineering Selection Recommendations

The 1945R-03K is a direct substitute for the obsolete 74F396AP-RC. Both components maintain identical inductance values, tolerance specifications, and operating temperature ranges. The substitute is currently in active production status, ensuring long-term availability and supply chain stability.

Both parts are ROHS3 compliant and REACH unaffected, meeting regulatory requirements for industrial and commercial applications. The 1945R-03K provides superior electrical performance with lower DC resistance and higher current rating, making it suitable for applications where the original 74F396AP-RC is no longer available.

Frequently Asked Questions (FAQ)

Q: Can the 1945R-03K replace the 74F396AP-RC in existing designs?

A: Yes. Both inductors share identical inductance values (3.9 µH), tolerance (±10%), shielding configuration (unshielded), mounting type (through-hole axial), and operating temperature range (-55°C to 125°C). The substitute is electrically and mechanically compatible.

Q: What are the differences between these two inductors?

A: The primary differences are core material (phenolic vs. iron), construction type (wirewound vs. molded), DC resistance (800mOhm vs. 190mOhm), and current rating (500 mA vs. 1.2 A). The 1945R-03K offers improved electrical performance with lower losses and higher current capacity.

Q: Are there any packaging differences?

A: Both components use through-hole axial packaging. The 1945R-03K has slightly smaller physical dimensions (0.193" Dia x 0.447" L vs. 0.200" Dia x 0.500" L), which may require PCB layout verification for tight spacing applications.

Q: Do both parts meet compliance standards?

A: Yes. Both the 74F396AP-RC and 1945R-03K are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components.

Q: Why is the 74F396AP-RC listed as obsolete?

A: The 74F396AP-RC has been discontinued by Bourns Inc. The 1945R-03K from API Delevan Inc. is an active production equivalent that provides equivalent functionality with improved performance characteristics.
