Key Parameters

Substitute Part Grouping Explanation

Substitution of the Murata 34L332C is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 3.3 µH (within ±30% tolerance specification)
• Shielding requirement: Shielded construction
• Mounting configuration: Surface mount
• Operating temperature range: -40°C to 125°C minimum
• Current handling capability: Minimum 1 A rating

Secondary Compatibility Factors:

• DC resistance performance relative to application requirements
• Physical package dimensions and height constraints
• RoHS and regulatory compliance status
• Moisture sensitivity level (MSL 1 acceptable)

The Bourns SRR4011-3R3YL meets all primary matching criteria with enhanced electrical performance characteristics, making it a direct functional substitute for the obsolete Murata part.

Parameter Comparison

Engineering Selection Recommendations

The Bourns SRR4011-3R3YL is the manufacturer-recommended substitute for the obsolete Murata 34L332C. Selection is based on the following engineering factors:

Electrical Compatibility: Both components share identical inductance values (3.3 µH) and tolerance specifications (±30%). The Bourns substitute provides superior current handling (1.6 A versus 1 A) and lower DC resistance (110 mOhm versus 150 mOhm), delivering improved thermal performance in the application.

Regulatory Compliance: The Bourns part maintains RoHS compliance with ROHS3 certification, exceeding the original RoHS Compliant status of the Murata component. Both parts carry MSL 1 rating and REACH Unaffected status, ensuring regulatory continuity.

Physical Integration: Dimensional differences are minimal. The Bourns part is slightly smaller in footprint (4.80mm versus 5.20mm) with negligible height increase (1.30mm versus 1.20mm), compatible with standard surface mount assembly processes.

Product Availability: The Bourns SRR4011-3R3YL is active production status with established supply chain availability, eliminating obsolescence risk associated with the original Murata component.

Frequently Asked Questions (FAQ)

Q: Can the Bourns SRR4011-3R3YL directly replace the Murata 34L332C in existing designs?

A: Yes. Both components share identical inductance values, tolerance specifications, shielding configuration, and operating temperature range. The Bourns part provides enhanced electrical performance with higher current rating and lower DC resistance, making it functionally compatible for direct substitution.

Q: What are the physical dimension differences between these parts?

A: The Bourns SRR4011-3R3YL has a slightly smaller footprint (4.80mm x 4.80mm versus 5.20mm x 5.20mm) and marginally greater height (1.30mm versus 1.20mm). These differences are within standard PCB layout tolerances for surface mount components.

Q: Are there compliance or certification differences?

A: The Bourns substitute carries ROHS3 certification compared to the original RoHS Compliant status. Both parts maintain MSL 1 rating and REACH Unaffected status. ROHS3 compliance represents an enhancement in regulatory standing.

Q: Why is the Bourns part rated for higher current (1.6 A versus 1 A)?

A: The Bourns SRR4011-3R3YL uses drum core construction with ferrite material, providing improved thermal characteristics and saturation performance compared to the original wirewound design. This enables higher current handling capability while maintaining the same inductance value.

Q: What is the saturation current specification for the substitute part?

A: The Bourns SRR4011-3R3YL has a saturation current (Isat) of 1.4 A, providing operational margin above the 1 A continuous rating of the original Murata component.

Q: Is packaging format compatible between these parts?

A: Both components use nonstandard surface mount packages. The Bourns part is supplied in Tape & Reel (TR) format. Verify PCB footprint compatibility with your design documentation before implementation.
