84334C Equivalent & Substitute Parts

Part Overview

The Murata Power Solutions Inc. 84334C is a 330 µH unshielded wirewound inductor rated for 170 mA with a maximum DC resistance of 6.5Ohm. This surface mount component operates across the temperature range of -40°C to 125°C and is classified as Active product status with ROHS3 compliance. Equivalent parts are identified when electrical and mechanical parameters align within specified tolerances, enabling direct substitution in circuit designs where the original part becomes unavailable or inventory constraints require alternative sourcing.

Key Parameters

Substitute Part Grouping Explanation

The Bourns Inc. SDR0403-331KL qualifies as an equivalent substitute based on the following critical parameters:

• Inductance value matches at 330 µH with identical ±10% tolerance
• Current rating is equivalent at 170 mA
• DC resistance specification of 6Ohm Max is within acceptable range relative to the 6.5Ohm Max of the main part
• Both components are unshielded surface mount inductors
• Operating temperature range is identical: -40°C ~ 125°C
• Both maintain ROHS3 compliance and MSL 1 rating
• Physical package classification is nonstandard for both parts

The SDR0403-331KL employs a drum core ferrite construction with documented saturation current of 250mA and self-resonant frequency of 4MHz, providing additional performance margin beyond the specified 170 mA rating.

Parameter Comparison

Engineering Selection Recommendations

Both the 84334C and SDR0403-331KL maintain Active product status with full regulatory compliance under ROHS3 and REACH standards. The SDR0403-331KL offers lower DC resistance at 6Ohm Max compared to the 6.5Ohm Max specification of the 84334C, resulting in reduced power dissipation in equivalent circuit applications. The Bourns component provides documented performance characteristics including saturation current of 250mA and self-resonant frequency of 4MHz, which exceed the minimum requirements for the 170 mA rated application. Selection between these parts should be based on availability, lead time requirements, and specific thermal management considerations within the target application.

Frequently Asked Questions (FAQ)

Q: Can the SDR0403-331KL directly replace the 84334C in existing designs?

A: Yes. Both inductors share identical inductance (330 µH), tolerance (±10%), current rating (170 mA), operating temperature range (-40°C ~ 125°C), and regulatory compliance. The SDR0403-331KL features lower DC resistance, which is advantageous for thermal performance.

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

A: The 84334C measures 0.177" L x 0.130" W x 0.114" H (4.50mm x 3.30mm x 2.90mm). The SDR0403-331KL measures 0.177" L x 0.157" W x 0.138" H (4.50mm x 4.00mm x 4.60mm). Length is identical; width and height are slightly larger on the Bourns component.

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

A: Yes. Both the 84334C and SDR0403-331KL are supplied in Tape & Reel (TR) packaging suitable for automated assembly processes.

Q: What is the difference in core material construction?

A: The 84334C uses a wirewound construction with unspecified core material. The SDR0403-331KL employs a drum core ferrite construction with wirewound topology, providing defined saturation characteristics at 250mA.

Q: Do both parts meet the same moisture sensitivity requirements?

A: Yes. Both components are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
