Bourns 9250-825-RC Equivalent & Substitute Parts

Part Overview

The Bourns 9250-825-RC is a fixed inductor with 8.2 mH inductance, rated for 26 mA maximum current, and 119 Ohm maximum DC resistance. This shielded drum core, wirewound inductor is designed for through-hole axial mounting applications operating across -55°C to 105°C. The part is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 9250-825-RC is determined by matching the following critical electrical and mechanical parameters:

• Inductance value: 8.2 mH
• Tolerance: ±10%
• Current rating: 26 mA minimum
• DC resistance: 119 Ohm maximum
• Q factor: 40 @ 250 kHz
• Self resonant frequency: 540 kHz
• Operating temperature range: minimum -55°C to 105°C
• Mounting type: Through hole axial
• Physical dimensions: 0.162" Dia x 0.410" L (4.11mm x 10.41mm)

Two substitute parts meet these criteria with variations in construction type and shielding configuration.

Parameter Comparison

Engineering Selection Recommendations

The Bourns 9250A-825-RC is the primary substitute for the obsolete 9250-825-RC. Both parts are manufactured by Bourns Inc., maintain identical electrical specifications, and feature shielded construction. The 9250A-825-RC is active in production with extended operating temperature range (-55°C to 125°C) and is available in bulk packaging. Both parts are ROHS3 compliant.

The TE Connectivity MSC60822KT provides an alternative substitute with matching electrical parameters and active product status. This part differs in shielding configuration (unshielded versus shielded) and is supplied in tape and box packaging. Selection of the MSC60822KT requires confirmation that unshielded construction is acceptable for the application, as electromagnetic interference characteristics will differ from the shielded original design.

Frequently Asked Questions (FAQ)

Q: Can the 9250A-825-RC directly replace the 9250-825-RC?

A: Yes. The 9250A-825-RC matches all critical electrical parameters: 8.2 mH inductance, 26 mA current rating, 119 Ohm maximum DC resistance, 40 Q @ 250 kHz, and 540 kHz self resonant frequency. Both parts feature shielded construction and identical physical dimensions. The 9250A-825-RC is active in production.

Q: What is the key difference between the 9250A-825-RC and MSC60822KT?

A: The primary difference is shielding. The 9250A-825-RC is shielded; the MSC60822KT is unshielded. All other electrical parameters are identical. Shielding affects electromagnetic interference performance and crosstalk characteristics. Application requirements determine which configuration is appropriate.

Q: Are all three parts physically interchangeable?

A: Yes, all three parts share identical physical dimensions (0.162" Dia x 0.410" L / 4.11mm x 10.41mm) and axial through-hole mounting configuration. PCB layout compatibility is maintained across all three options.

Q: What compliance certifications apply to these parts?

A: All three parts are ROHS3 compliant and carry EAR99 ECCN classification. The 9250-825-RC and MSC60822KT operate across -55°C to 105°C; the 9250A-825-RC extends to -55°C to 125°C.

Q: Which substitute should be selected for new designs?

A: The Bourns 9250A-825-RC is recommended for new designs due to active production status, extended temperature range, and shielded construction matching the original design intent. The MSC60822KT is suitable only when unshielded operation is confirmed acceptable.
