84333C Equivalent & Substitute Parts

Part Overview

The Murata Power Solutions Inc. 84333C is a 33 µH unshielded wirewound inductor rated for 550 mA continuous current with a maximum DC resistance of 860mOhm. This surface mount component operates across the -40°C to 125°C temperature range and is designed for applications requiring fixed inductance in compact nonstandard packaging. The part maintains Active product status and is ROHS3 compliant. Equivalent parts are identified when they maintain the same inductance value, tolerance, operating temperature range, and mounting type while meeting or exceeding the current rating and DC resistance specifications.

Key Parameters

Substitute Part Grouping Explanation

The SDR0403-330KL from Bourns Inc. qualifies as an equivalent substitute based on the following criteria:

Matching Parameters:

• Inductance: 33 µH (identical)
• Tolerance: ±10% (identical)
• Operating Temperature: -40°C ~ 125°C (identical)
• Mounting Type: Surface Mount (identical)
• Shielding: Unshielded (identical)
• RoHS Status: ROHS3 Compliant (identical)

Superior Performance Characteristics:

• Current Rating: 640 mA (exceeds 550 mA requirement)
• DC Resistance: 540mOhm Max (lower than 860mOhm maximum)

The substitute part maintains all critical electrical and thermal specifications while providing improved current handling capacity and reduced DC resistance, making it suitable for direct replacement in applications using the 84333C.

Parameter Comparison

Engineering Selection Recommendations

Both the 84333C and SDR0403-330KL maintain Active product status with ROHS3 compliance and REACH unaffected designation. The SDR0403-330KL provides enhanced electrical performance through higher current rating capacity and lower DC resistance while preserving all critical functional parameters. Selection between these parts should be based on specific application requirements regarding current handling and thermal dissipation characteristics. Both components are suitable for applications requiring 33 µH inductance in surface mount configurations across the specified temperature range.

Frequently Asked Questions (FAQ)

Q: Can the SDR0403-330KL directly replace the 84333C in existing designs?

A: Yes. Both parts share identical inductance (33 µH), tolerance (±10%), operating temperature range (-40°C ~ 125°C), mounting type (Surface Mount), and shielding characteristics (Unshielded). The substitute part exceeds the current rating and provides lower DC resistance.

Q: What are the key differences between these inductors?

A: The primary differences are manufacturer origin (Murata versus Bourns), current rating (550 mA versus 640 mA), and DC resistance (860mOhm Max versus 540mOhm Max). The SDR0403-330KL offers improved electrical performance in both parameters.

Q: Are there any packaging or dimensional considerations?

A: Both parts use Tape & Reel (TR) packaging and nonstandard case dimensions. The 84333C measures 0.177" L x 0.130" W x 0.114" H (4.50mm x 3.30mm x 2.90mm). The SDR0403-330KL measures 0.177" L x 0.157" W x 0.138" H (4.50mm x 4.00mm x 4.60mm). Verify PCB layout compatibility before substitution.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 84333C and SDR0403-330KL are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8504.50.4000.
