Substitute Part Grouping Explanation

Substitution of the Bourns 9250-823 is determined by strict equivalence across the following critical parameters:

• Inductance value: 82 µH with ±10% tolerance
• Current rating: 180 mA minimum
• Saturation current: 140 mA minimum
• DC resistance: 2.44 Ohm maximum
• Shielding requirement: Shielded configuration
• Core material: Ferrite
• Mounting configuration: Through-hole axial package
• Physical dimensions: 0.162" Dia x 0.410" L (4.11mm x 10.41mm)
• Q factor: 50 @ 2.5 MHz
• Self-resonant frequency: 10.5 MHz

The Bourns 9250A-823-RC qualifies as a direct substitute based on matching all electrical and mechanical parameters. The primary distinction is the transition from drum core to molded construction and advancement from obsolete to active product status.

Parameter Comparison

Engineering Selection Recommendations

The Bourns 9250A-823-RC is the direct substitute for the obsolete 9250-823. Selection is based on the following engineering criteria:

Product Status: The 9250-823 is obsolete, while the 9250A-823-RC is active. Active product status ensures ongoing availability, manufacturing support, and supply chain continuity.

Electrical Equivalence: Both parts maintain identical inductance (82 µH), current rating (180 mA), saturation current (140 mA), DC resistance (2.44 Ohm max), and frequency characteristics (Q @ 2.5 MHz = 50, self-resonant frequency = 10.5 MHz).

Mechanical Compatibility: Both components share identical through-hole axial package dimensions (0.162" Dia x 0.410" L / 4.11mm x 10.41mm), ensuring direct PCB footprint compatibility.

Regulatory Compliance: The 9250A-823-RC achieves ROHS3 compliance, whereas the 9250-823 is RoHS non-compliant. Both maintain REACH Unaffected status.

Operating Temperature: The 9250A-823-RC extends the upper operating temperature limit to 125°C compared to 105°C for the 9250-823, providing enhanced thermal margin for demanding applications.

Construction Difference: The transition from drum core wirewound to molded construction in the 9250A-823-RC represents a manufacturing evolution that maintains all specified electrical and mechanical parameters while improving reliability and consistency.

Frequently Asked Questions (FAQ)

Q: Can the 9250A-823-RC be used as a direct replacement for the 9250-823 in existing designs?

A: Yes. The 9250A-823-RC is electrically and mechanically equivalent to the 9250-823. Both components share identical inductance, current rating, DC resistance, frequency characteristics, and through-hole axial package dimensions. No circuit modifications are required.

Q: What is the primary difference between the 9250-823 and 9250A-823-RC?

A: The main differences are product status (obsolete vs. active), core construction (drum core wirewound vs. molded), operating temperature range (-55°C to 105°C vs. -55°C to 125°C), and regulatory compliance (RoHS non-compliant vs. ROHS3 compliant). All electrical specifications remain identical.

Q: Are the physical dimensions identical between these two parts?

A: Yes. Both the 9250-823 and 9250A-823-RC have identical dimensions of 0.162" Dia x 0.410" L (4.11mm x 10.41mm), ensuring compatibility with existing PCB layouts and through-hole mounting patterns.

Q: Does the 9250A-823-RC meet current regulatory requirements?

A: Yes. The 9250A-823-RC is ROHS3 compliant and REACH Unaffected, meeting current regulatory standards. The 9250-823 is RoHS non-compliant and may not be suitable for applications subject to RoHS requirements.

Q: What is the saturation current specification, and why is it important?

A: Both parts have a saturation current (Isat) of 140 mA. This specification indicates the maximum current level before the inductor begins to saturate and inductance degrades. The 180 mA current rating provides operational margin above saturation.

Q: Are there any packaging differences between these parts?

A: The 9250-823 is supplied in standard packaging, while the 9250A-823-RC is supplied in bulk packaging. Both maintain identical component specifications and through-hole axial configuration.
