Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Murata 15224C is determined by the following criteria:

Primary Electrical Parameters:

• Inductance value: 220 µH with ±10% tolerance
• Mounting configuration: Through-hole radial, vertical cylinder form factor
• Shielding classification: Unshielded

Secondary Electrical Parameters:

• Current rating must support the application requirement
• DC resistance must be within acceptable limits for the circuit design
• Operating temperature range must encompass the application environment

Compliance & Certification:

• RoHS3 compliance status
• REACH compliance status

The Bourns 1110-221K-RC meets the primary electrical and mechanical criteria with equivalent inductance and form factor. Differences in current rating (1.6 A vs 2.08 A) and DC resistance (240mOhm vs 185mOhm) require application-level evaluation.

Parameter Comparison

Engineering Selection Recommendations

Both the Murata 15224C and Bourns 1110-221K-RC maintain Active product status with full RoHS3 and REACH compliance. Selection between these parts depends on application-specific current and thermal requirements. The Murata 15224C provides higher current capacity at 2.08 A with lower DC resistance. The Bourns 1110-221K-RC offers an extended operating temperature range of -55°C to 105°C, suitable for applications requiring broader thermal performance. Physical dimensions are equivalent within manufacturing tolerances.

Frequently Asked Questions (FAQ)

Q: Can the Bourns 1110-221K-RC replace the Murata 15224C in all applications?

A: Substitution is valid when the application current requirement does not exceed 1.6 A and the operating temperature range falls within -55°C to 105°C. The higher DC resistance of the Bourns part (240mOhm vs 185mOhm) must be evaluated for thermal and efficiency impacts in the circuit design.

Q: Are the physical dimensions compatible?

A: Yes. Both parts use radial, vertical cylinder packaging with equivalent form factors. The Murata 15224C measures 0.661" diameter (16.80mm) with 0.839" seated height (21.30mm). The Bourns 1110-221K-RC measures 0.660" diameter (16.76mm) with 0.840" seated height (21.34mm). Dimensional differences are within standard manufacturing tolerances for PCB footprint compatibility.

Q: What is the inductance tolerance for both parts?

A: Both the Murata 15224C and Bourns 1110-221K-RC specify ±10% inductance tolerance at their respective test frequencies (10 kHz and 1 kHz).

Q: Are both parts RoHS3 compliant?

A: Yes. Both the Murata 15224C and Bourns 1110-221K-RC are ROHS3 compliant and REACH unaffected, meeting current environmental regulations for electronic component manufacturing and distribution.
