Substitute Part Grouping Explanation

The Bourns SDR0403-101KL qualifies as an equivalent substitute for the Murata 84104C based on the following critical parameters:

Inductance matching: Both parts are rated at 100 µH with ±10% tolerance, ensuring functional equivalence in circuit applications.

Current rating compatibility: The substitute part is rated at 350 mA, which exceeds the main part's 300 mA requirement, providing adequate headroom for the application.

DC resistance: The substitute's 1.9Ohm Max DCR is lower than the main part's 2Ohm Max, representing an improvement in electrical performance.

Operating temperature range: Both parts operate across -40°C to 125°C, ensuring thermal compatibility.

Regulatory compliance: Both parts are ROHS3 Compliant and REACH Unaffected, meeting the same environmental standards.

Mounting and packaging: Both are surface mount components in nonstandard packages with compatible MSL ratings of 1 (Unlimited).

Parameter Comparison

Engineering Selection Recommendations

Both the Murata 84104C and Bourns SDR0403-101KL are Active products with identical ROHS3 and REACH compliance certifications. The Bourns substitute provides equivalent inductance and tolerance specifications while offering improved electrical characteristics through lower DC resistance and higher current rating capacity. Selection between these parts should be based on availability, lead time, and cost considerations, as both meet the specified regulatory and performance requirements for 100 µH unshielded wirewound inductor applications in surface mount configurations.

Frequently Asked Questions (FAQ)

Q: Can the Bourns SDR0403-101KL directly replace the Murata 84104C in existing designs?

A: Yes. Both parts share identical inductance (100 µH), tolerance (±10%), operating temperature range (-40°C to 125°C), and regulatory compliance (ROHS3, REACH). The substitute's higher current rating (350 mA vs. 300 mA) and lower DC resistance (1.9Ohm vs. 2Ohm) represent performance improvements.

Q: Are there physical dimension differences between these parts?

A: Both parts are nonstandard surface mount packages. The Murata 84104C measures 4.50mm × 3.30mm × 2.90mm (max height), while the Bourns SDR0403-101KL measures 4.50mm × 4.00mm × 4.60mm (max height). Verify PCB layout compatibility before substitution.

Q: Do both parts have the same moisture sensitivity rating?

A: Yes. Both parts carry MSL Rating 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: What is the primary difference in core construction?

A: The Murata 84104C uses a standard wirewound core, while the Bourns SDR0403-101KL uses a drum core wirewound construction with ferrite material. Both are unshielded and functionally equivalent for the specified inductance and current parameters.

Q: Are both parts available in Tape & Reel packaging?

A: Yes. Both the Murata 84104C and Bourns SDR0403-101KL are supplied in Tape & Reel (TR) packaging suitable for automated assembly processes.
