Substitute Part Grouping Explanation

The 2309-H-RC qualifies as a direct substitute based on identical electrical and mechanical parameters. Substitution eligibility is determined by the following criteria:

  • Inductance value: 47 µH (exact match)
  • Inductance tolerance: ±15% (exact match)
  • Current rating: 10.7 A (exact match)
  • DC resistance: 16 mOhm maximum (exact match)
  • Core material: Iron Powder (exact match)
  • Shielding configuration: Unshielded (exact match)
  • Mounting type: Through Hole (exact match)
  • Package configuration: Radial, Horizontal (Open) (exact match)
  • Operating temperature range: -55°C to 105°C (exact match)
  • Physical dimensions: 1.280" diameter, 0.650" height (exact match)

The 2309-H-RC maintains all functional and mechanical specifications required for direct replacement in applications originally designed for the 2309-H.

Engineering Selection Recommendations

The 2309-H-RC is the appropriate selection for applications currently using the obsolete 2309-H. Both parts are manufactured by Bourns Inc. within the 2300 series and maintain identical electrical and mechanical specifications.

The primary distinction between the two parts is product status and regulatory compliance. The 2309-H carries obsolete status with RoHS non-compliant certification, while the 2309-H-RC is an active product with ROHS3 compliance. For new designs or production requiring regulatory compliance with current environmental standards, the 2309-H-RC is the specified choice. Both parts maintain identical REACH and ECCN classifications.

Frequently Asked Questions (FAQ)

Q: Can the 2309-H-RC be used as a direct replacement for the 2309-H?

A: Yes. The 2309-H-RC is electrically and mechanically identical to the 2309-H. All functional parameters, including inductance, current rating, DC resistance, core material, and physical dimensions, are identical. The substitute part maintains the same through-hole radial horizontal mounting configuration.

Q: What is the difference between the 2309-H and 2309-H-RC?

A: The primary differences are product status and regulatory compliance. The 2309-H is obsolete and RoHS non-compliant. The 2309-H-RC is an active product with ROHS3 compliance. Electrical and mechanical specifications are identical.

Q: Are there packaging differences between these parts?

A: The 2309-H is supplied in standard packaging, while the 2309-H-RC is supplied in bulk packaging. Both parts are identical in form, fit, and function. Packaging differences do not affect component performance or compatibility.

Q: What is the inductance tolerance for these parts?

A: Both the 2309-H and 2309-H-RC have an inductance tolerance of ±15% at 1 kHz test frequency.

Q: Are these parts suitable for high-temperature applications?

A: Both parts are rated for operation across the temperature range of -55°C to 105°C, making them suitable for industrial and extended temperature applications within this range.

Q: What core material is used in these inductors?

A: Both the 2309-H and 2309-H-RC use iron powder core construction. The unshielded toroidal design is suitable for applications where external magnetic field interference is not a primary concern.
