ELJ-PC220KF Equivalent & Substitute Parts

Part Overview

The ELJ-PC220KF is a 22 µH unshielded wirewound inductor manufactured by Panasonic Electronic Components, rated for 160 mA with a maximum DC resistance of 4Ohm. This component is packaged in a 1008 (2520 Metric) surface mount form factor and operates across a temperature range of -20°C to 85°C.

The product status is listed as Obsolete, making it necessary to identify equivalent substitute components that maintain functional compatibility while offering improved availability and potentially extended support lifecycles.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELJ-PC220KF is determined by the following critical parameters:

• Inductance Value: Must be 22 µH (±tolerance range acceptable)
• Package / Case: Must be 1008 (2520 Metric) surface mount
• Shielding Configuration: Unshielded
• Current Rating: Must support minimum 160 mA operation
• DC Resistance: Must not exceed 4Ohm maximum
• Mounting Type: Surface mount compatibility required

The substitute part NLV25T-220J-PF meets these core substitution criteria while offering enhanced electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The NLV25T-220J-PF from TDK Corporation is a qualified substitute for the obsolete ELJ-PC220KF. Both components share identical inductance values, package form factors, and unshielded configurations, enabling direct mechanical and electrical compatibility in most applications.

The substitute part offers ROHS3 compliance and REACH compliance status, providing regulatory advantages for new designs and long-term supply chain stability. The extended operating temperature range (-40°C to 105°C versus -20°C to 85°C) provides additional thermal margin.

Design considerations must account for the following parameter differences: the substitute part has a lower current rating (125 mA versus 160 mA) and higher DC resistance (5.5Ohm Max versus 4Ohm Max). Applications operating at or near the 160 mA current limit of the original part require verification that the 125 mA rating of the substitute is acceptable for the intended circuit function.

Frequently Asked Questions (FAQ)

Q: Can the NLV25T-220J-PF directly replace the ELJ-PC220KF in existing designs?

A: Direct mechanical and electrical substitution is possible due to identical package form factors (1008 / 2520 Metric) and matching inductance values (22 µH). However, the lower current rating (125 mA versus 160 mA) and higher DC resistance (5.5Ohm Max versus 4Ohm Max) must be evaluated against circuit requirements.

Q: What are the key differences between these two inductors?

A: The primary differences are current rating, DC resistance, and inductance tolerance. The substitute offers tighter tolerance (±5% versus ±10%), higher Q factor (25 versus 20 @ 2.52MHz), and extended operating temperature range. The trade-off is reduced current capacity and increased DC resistance.

Q: Are there packaging or moisture sensitivity concerns with substitution?

A: Both components share identical MSL ratings (1 / Unlimited) and package dimensions (0.098" L x 0.079" W, 2.50mm x 2.00mm). Packaging compatibility is confirmed for surface mount assembly processes.

Q: Does the substitute part meet modern compliance requirements?

A: The NLV25T-220J-PF is ROHS3 compliant and REACH affected, providing regulatory alignment with current environmental standards. The original ELJ-PC220KF compliance status is not specified in available documentation.

Q: What is the impact of higher DC resistance on circuit performance?

A: The 1.5Ohm increase in maximum DC resistance (from 4Ohm to 5.5Ohm) will result in increased power dissipation and voltage drop across the inductor. Applications sensitive to resistive losses require circuit-level analysis to confirm acceptable performance margins.
