ELC-09D220F Equivalent & Substitute Parts

Part Overview

The ELC-09D220F is a 22 µH unshielded wirewound inductor manufactured by Panasonic Electronic Components, rated for 1.8 A with 51mOhm DC resistance. This component is classified as obsolete, making identification of compatible substitute parts essential for ongoing design support and procurement continuity. The through-hole radial mounting configuration and specific electrical characteristics define the scope for equivalent component selection.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ELC-09D220F is determined by the following critical parameters:

• Inductance Value: 22 µH (primary electrical requirement)
• Current Rating: Minimum 1.8 A (functional requirement for circuit operation)
• DC Resistance: Must be compatible with circuit design specifications
• Mounting Type: Through hole configuration required for PCB compatibility
• Package Geometry: Radial, vertical cylinder form factor for mechanical fit
• Shielding Classification: Unshielded designation maintained

The AIUR-09-220M from Abracon LLC meets these substitution criteria. While it exhibits higher DC resistance (92mOhm max versus 51mOhm) and broader inductance tolerance (±20% versus ±10%), it maintains the same 22 µH inductance value, exceeds the current rating requirement at 2.4 A, and preserves the through-hole radial mounting configuration and unshielded design.

Parameter Comparison

Engineering Selection Recommendations

The AIUR-09-220M is suitable as a substitute for the ELC-09D220F based on the following factors:

• Product Status: The AIUR-09-220M maintains active production status, ensuring long-term availability and supply chain continuity compared to the obsolete ELC-09D220F.
• Compliance: Both components are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings, meeting equivalent environmental and regulatory requirements.
• Electrical Compatibility: The AIUR-09-220M provides higher current capacity (2.4 A versus 1.8 A), offering design margin for the original circuit application. The increased DC resistance (92mOhm max) must be evaluated against circuit power dissipation and performance tolerances.
• Mechanical Fit: While the AIUR-09-220M exhibits slightly larger diameter (0.394" versus 0.374") and reduced height (0.256" versus 0.350"), both maintain radial vertical cylinder geometry suitable for through-hole PCB mounting.

Frequently Asked Questions (FAQ)

Q: Can the AIUR-09-220M directly replace the ELC-09D220F without circuit modification?

A: Direct substitution is mechanically and electrically feasible for most applications. The primary consideration is the increased DC resistance of the AIUR-09-220M (92mOhm max versus 51mOhm), which will result in higher power dissipation. Circuit analysis is required to confirm this increase remains within acceptable operating parameters.

Q: What is the impact of the ±20% inductance tolerance on the AIUR-09-220M compared to the ±10% tolerance of the ELC-09D220F?

A: The broader tolerance of the AIUR-09-220M introduces greater inductance variation across the component population. Applications with tight inductance specifications should account for this wider tolerance band in circuit design and performance validation.

Q: Are there mechanical clearance concerns with the slightly larger diameter of the AIUR-09-220M?

A: The AIUR-09-220M diameter is 0.394" (10.00mm) compared to 0.374" (9.50mm) for the ELC-09D220F. PCB layout verification is necessary to confirm adequate clearance in the original mounting location. The reduced height of the AIUR-09-220M (0.256" versus 0.350") may provide additional design flexibility.

Q: Do both components share equivalent environmental ratings?

A: Both the ELC-09D220F and AIUR-09-220M carry ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity ratings. The AIUR-09-220M specifies an operating temperature range of -55°C to 85°C. Confirm this range aligns with the original application requirements.

Q: What is the primary advantage of selecting the AIUR-09-220M?

A: The AIUR-09-220M is in active production status, ensuring reliable procurement and supply chain continuity. The higher current rating (2.4 A) provides additional design margin compared to the 1.8 A rating of the obsolete ELC-09D220F.
