Key Parameters

Substitute Part Grouping Explanation

Substitution of the 34332C is determined by strict equivalence in the following electrical and mechanical parameters:

• Inductance value: 3.3 µH within ±30% tolerance
• Current rating: minimum 1.5 A continuous
• DC resistance: maximum 80mOhm
• Shielding requirement: shielded construction
• Operating temperature range: -40°C to 125°C minimum
• Mounting type: surface mount
• Height constraint: 0.079 inches (2.00 mm) maximum seated height
• Regulatory compliance: RoHS3 and REACH requirements

The substitute part SRR4018-3R3Y meets all mandatory electrical parameters with improved current rating (1.95 A) and lower DC resistance (65mOhm), while maintaining identical inductance, shielding, temperature range, and compliance certifications. Physical dimensions remain compatible within the specified height constraint.

Parameter Comparison

Engineering Selection Recommendations

The SRR4018-3R3Y from Bourns Inc. is a direct substitute for the 34332C. Both components maintain identical inductance values, tolerance specifications, operating temperature ranges, and regulatory compliance status. The substitute part provides improved electrical performance through higher current saturation rating (1.95 A versus 1.5 A) and reduced DC resistance (65mOhm versus 80mOhm maximum), resulting in lower power dissipation in equivalent circuit applications. Both parts are active products with full RoHS3 and REACH compliance. Physical compatibility is maintained with identical seated height specifications, enabling direct board-level substitution without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the SRR4018-3R3Y replace the 34332C in existing designs?

A: Yes. Both inductors share identical inductance (3.3 µH), tolerance (±30%), operating temperature range (-40°C to 125°C), shielding, and physical height (0.079 inches). The substitute part meets or exceeds all electrical specifications of the original component.

Q: What are the key differences between these two inductors?

A: The primary differences are manufacturer (Murata versus Bourns), core material type (unspecified versus ferrite drum core), current rating (1.5 A versus 1.95 A), and DC resistance (80mOhm versus 65mOhm maximum). The substitute provides superior current handling and lower resistance characteristics.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the 34332C and SRR4018-3R3Y are RoHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Q: Do these inductors have identical package dimensions?

A: Both parts are surface mount with identical seated height of 0.079 inches (2.00 mm). The 34332C uses a nonstandard package while the SRR4018-3R3Y uses a 1919 (4848 Metric) package. Footprint compatibility should be verified for specific PCB designs.

Q: What is the inductance test frequency for these parts?

A: The SRR4018-3R3Y is tested at 100 kHz. The test frequency for the 34332C is not specified in the provided data.
