Substitute Part Grouping Explanation

Substitute parts for the 70F827AP-RC are identified based on the following critical parameters that must align for functional equivalence:

  • Inductance Value: 820 nH (exact match required)
  • Tolerance: ±20% (matching tolerance specification)
  • Shielding Configuration: Unshielded (same electromagnetic profile)
  • Mounting Type: Through Hole (same installation method)
  • Package / Case: Axial (same form factor)
  • Operating Temperature Range: -55°C to 125°C (same thermal operating window)
  • Core Material: Phenolic (same dielectric material)
  • Inductance Test Frequency: 25 MHz (same measurement standard)

The 1944R-12M from API Delevan Inc. meets all these critical parameters and qualifies as a functional substitute. While the 1944R-12M exhibits different construction type (molded versus wirewound), current rating (1.3 A versus 830 mA), and DC resistance (160 mOhm versus 290 mOhm), these differences represent performance enhancements rather than incompatibilities. The substitute part maintains identical inductance, tolerance, shielding, mounting, package, temperature range, core material, and test frequency specifications.

Engineering Selection Recommendations

The 1944R-12M qualifies as a direct functional substitute for the 70F827AP-RC based on matching inductance, tolerance, shielding, mounting configuration, package form factor, operating temperature range, core material, and test frequency specifications.

The 1944R-12M carries active product status, ensuring ongoing availability and manufacturer support, whereas the 70F827AP-RC is obsolete. Both components maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for equivalent applications.

The 1944R-12M demonstrates superior electrical performance characteristics: higher current rating (1.3 A versus 830 mA) and lower DC resistance (160 mOhm versus 290 mOhm). These enhancements provide increased design margin and reduced power dissipation in applications where the original 70F827AP-RC was specified.

Frequently Asked Questions (FAQ)

Q: Can the 1944R-12M directly replace the 70F827AP-RC in existing designs?

A: Yes. Both components share identical inductance value (820 nH), tolerance (±20%), shielding configuration (unshielded), mounting type (through hole), package form factor (axial), operating temperature range (-55°C to 125°C), core material (phenolic), and test frequency (25 MHz). These parameters define functional equivalence for inductor substitution.

Q: What are the physical differences between these parts?

A: The 70F827AP-RC measures 0.120" diameter × 0.310" length (3.05mm × 7.87mm) and uses wirewound construction. The 1944R-12M measures 0.193" diameter × 0.447" length (4.90mm × 11.35mm) and uses molded construction. The larger physical dimensions of the 1944R-12M must be verified against available board space in the target application.

Q: How do the electrical performance characteristics compare?

A: The 1944R-12M provides higher current capacity (1.3 A versus 830 mA) and lower DC resistance (160 mOhm versus 290 mOhm), resulting in reduced power dissipation. Quality factor at 25 MHz is comparable (45 versus 48), and self-resonant frequency is similar (220 MHz versus 216 MHz).

Q: Are both components compliant with current regulatory standards?

A: Yes. Both the 70F827AP-RC and 1944R-12M are ROHS3 compliant and REACH unaffected, meeting current environmental and hazardous substance regulations.

Q: What is the availability status of each component?

A: The 70F827AP-RC is classified as obsolete. The 1944R-12M maintains active product status with ongoing manufacturer support and supply availability.
