ELC-10E332L Equivalent & Substitute Parts

Part Overview

The ELC-10E332L is a 3.3 mH shielded wirewound inductor manufactured by Panasonic Electronic Components, rated for 170 mA with 5.9Ohm DC resistance. This through-hole radial component operates at 10 kHz test frequency and is housed in a vertical cylinder package measuring 10.00mm diameter by 13.00mm height. The product is marked as obsolete, necessitating identification of functionally equivalent alternatives for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELC-10E332L is determined by the following critical parameters:

Inductance Value: 3.3 mH ±10% tolerance is the primary functional requirement. Substitute parts must maintain this inductance specification.

Current Rating: The main part supports 170 mA. Substitute parts must equal or exceed this current capacity to ensure safe operation without thermal stress.

Shielding: Both the main part and substitute must provide shielded construction to maintain electromagnetic isolation in the target application.

Mounting Configuration: Through-hole radial vertical cylinder packaging is required for mechanical compatibility with existing PCB layouts.

Regulatory Compliance: ROHS3 compliance is mandatory for environmental and supply chain requirements.

The Würth Elektronik 744731332 meets these substitution criteria with matching inductance (3.3 mH), higher current rating (180 mA), shielded construction, identical mounting type, and ROHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

The Würth Elektronik 744731332 is a direct functional substitute for the obsolete ELC-10E332L. Both components maintain identical inductance values and tolerance specifications, with the substitute offering improved current capacity (180 mA versus 170 mA). The substitute's higher DC resistance (8Ohm Max versus 5.9Ohm) represents a minor increase in power dissipation that must be evaluated within the specific circuit context.

Both parts carry ROHS3 compliance, ensuring regulatory alignment. The Würth Elektronik component is currently in active production status with documented inventory availability, providing supply chain continuity for the obsolete Panasonic part.

Frequently Asked Questions (FAQ)

Q: Can the 744731332 directly replace the ELC-10E332L in existing designs?

A: Yes. Both components share identical inductance (3.3 mH ±10%), shielded construction, through-hole radial vertical cylinder packaging, and ROHS3 compliance. The substitute's higher current rating (180 mA) and operating temperature range (-40°C ~ 125°C) provide enhanced performance margins.

Q: What is the impact of the higher DC resistance in the substitute part?

A: The 744731332 exhibits 8Ohm maximum DC resistance compared to the ELC-10E332L's 5.9Ohm. This 2.1Ohm difference increases resistive losses proportionally to current squared. Circuit-level thermal analysis is required to confirm acceptability within the application's power budget.

Q: Are there physical dimension differences between these parts?

A: Yes. The ELC-10E332L measures 10.00mm diameter by 13.00mm height. The 744731332 measures 7.80mm diameter by 7.50mm height. The substitute's smaller footprint may provide PCB layout advantages but requires verification of mechanical clearance in existing designs.

Q: What is the difference in inductance test frequency between these parts?

A: The ELC-10E332L is tested at 10 kHz while the 744731332 is tested at 1 kHz. Both maintain the specified 3.3 mH inductance within their respective test conditions. Application-specific frequency response requirements should be evaluated if operation occurs significantly outside these test frequencies.

Q: Are both parts compliant with current environmental regulations?

A: Yes. Both the ELC-10E332L and 744731332 are ROHS3 compliant. The 744731332 additionally carries REACH Unaffected status, confirming compliance with European chemical regulations.
