PD54R-222M

Part Overview

The PD54R-222M is a 2.2 µH unshielded drum core wirewound inductor manufactured by API Delevan Inc., designed for surface mount applications with a current rating of 2.4 A and maximum DC resistance of 64 mOhm. The component is active in production and ROHS3 compliant, serving as a critical passive element in power conversion, filtering, and signal conditioning circuits. Alternative components become necessary when supply constraints, inventory requirements, or specific performance parameters require selection from qualified substitute parts meeting equivalent electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

The SDR0604-2R2ML qualifies as an electrical equivalent based on the following critical substitution parameters:

Core Electrical Parameters:

• Identical inductance value: 2.2 µH
• Matching inductance tolerance: ±20%
• Equivalent core construction: Ferrite drum core, wirewound, unshielded
• Higher current rating: 2.8 A (exceeds PD54R-222M requirement of 2.4 A)
• Lower DC resistance: 60 mOhm (improved performance margin vs. 64 mOhm max)

Mechanical and Environmental Compatibility:

• Surface mount construction compatible with PD54R-222M footprint
• Operating temperature range: -40°C to 125°C (overlaps primary operating window)
• MSL 1 rating (equivalent moisture sensitivity)
• RoHS3 and REACH compliance (matching environmental standards)

Packaging Consideration: The substitute part is supplied in Cut Tape (CT) & Digi-Reel® format rather than standard Tape & Reel. This distinction affects ordering and handling procedures but does not affect electrical functionality.

Parameter Comparison

Engineering Selection Recommendations

PD54R-222M is the primary recommendation when the extended operating temperature range of -55°C to 125°C is required, particularly for applications operating below -40°C. This component maintains active production status with full RoHS3 and REACH compliance.

SDR0604-2R2ML serves as the qualified substitute when PD54R-222M availability is constrained. The substitute provides superior electrical characteristics with higher current rating and lower DC resistance, reducing thermal dissipation in the inductor. This component is also active in production with equivalent RoHS3 and REACH compliance. Substitution is acceptable for applications with minimum operating temperature of -40°C or higher.

Both components meet the core performance requirements for 2.2 µH unshielded ferrite drum core inductors at 2.4 A operation. Selection between them depends on availability, temperature range requirements, packaging format preferences (Tape & Reel vs. Cut Tape & Digi-Reel), and PCB layout considerations regarding the minor dimensional variance.

Frequently Asked Questions (FAQ)

Q: Can SDR0604-2R2ML be used directly in place of PD54R-222M? A: SDR0604-2R2ML is electrically compatible and suitable for applications operating at -40°C minimum. Physical dimensions differ slightly (5.80mm × 5.80mm vs. 5.70mm × 5.11mm); PCB footprint and circuit board layout must accommodate the larger substitute package dimensions. No functional electrical barriers to substitution exist for applications within the overlapping temperature range.

Q: What is the primary reason for seeking a substitute part? A: Substitution is typically driven by supply availability, inventory optimization, cost considerations, or required packaging formats. Both components satisfy the same electrical circuit requirements and environmental compliance standards.

Q: Are there temperature operating limitations with the substitute? A: SDR0604-2R2ML has a minimum operating temperature of -40°C versus -55°C for the PD54R-222M. If applications require operation below -40°C, the primary part PD54R-222M must be selected. Both components operate identically up to 125°C maximum.

Q: How do the current and resistance specifications affect substitution? A: SDR0604-2R2ML has a 2.8 A current rating and 60 mOhm maximum DC resistance, both superior to PD54R-222M specifications (2.4 A, 64 mOhm). The substitute provides better thermal performance and higher current handling capability, making it suitable for the specified 2.4 A design point.

Q: What is the difference in packaging between these parts? A: PD54R-222M is supplied in Tape & Reel (TR) format. SDR0604-2R2ML uses Cut Tape (CT) & Digi-Reel® packaging. These differences affect component ordering, handling procedures, and potentially reel compatibility with automated pick-and-place equipment, but do not affect electrical performance.

Q: Are both components compliant with industry standards? A: Both PD54R-222M and SDR0604-2R2ML are ROHS3 compliant and REACH unaffected. Both have MSL 1 (unlimited) moisture sensitivity rating. Compliance profiles are equivalent for deployment in regulated applications.
