PD104R-224K Equivalent & Substitute Parts

Part Overview

The PD104R-224K is a 220 µH unshielded drum core wirewound inductor manufactured by API Delevan Inc. This surface mount component is rated for 530 mA continuous current with a maximum DC resistance of 720 mOhm and operates across the temperature range of -55°C to 125°C. The part is ROHS3 compliant and carries an active product status. Substitute parts are identified to provide alternative sourcing options when the primary component is unavailable or when design requirements permit equivalent electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PD104R-224K is determined by the following critical parameters:

Inductance Value: Both the main part and substitute must maintain 220 µH inductance at 1 kHz test frequency with ±10% tolerance to ensure circuit performance equivalence.

Core Material and Type: Ferrite drum core construction is required to maintain electromagnetic characteristics and thermal stability across the operating temperature range.

Shielding Configuration: Unshielded construction must be preserved to maintain EMI characteristics and physical form factor compatibility.

Current Rating: The substitute part must support the required current without saturation. The PD104R-224K operates at 530 mA; substitute parts with equal or higher current ratings are acceptable.

DC Resistance: Maximum DCR of 720 mOhm establishes the upper limit for power dissipation and thermal performance. Substitute parts with DCR at or below this threshold maintain thermal and electrical equivalence.

Mounting and Package: Surface mount nonstandard package configuration must be maintained for PCB assembly compatibility.

Compliance: ROHS3 compliance and MSL rating of 1 (Unlimited) are required for manufacturing and environmental standards adherence.

Parameter Comparison

Engineering Selection Recommendations

The SDR1006-221KL from Bourns Inc. qualifies as an electrical substitute for the PD104R-224K based on the following criteria:

Inductance Equivalence: Both parts maintain 220 µH inductance at ±10% tolerance, ensuring circuit performance compatibility.

Current Capacity: The SDR1006-221KL provides 660 mA current rating and 1.1 A saturation current, exceeding the PD104R-224K requirement of 530 mA. This provides additional design margin.

DC Resistance: The SDR1006-221KL DCR of 730 mOhm Max is within 10 mOhm of the PD104R-224K specification, maintaining equivalent thermal and power dissipation characteristics.

Compliance Status: Both parts are ROHS3 compliant with MSL rating of 1 (Unlimited), meeting manufacturing and environmental requirements.

Temperature Range Consideration: The PD104R-224K operates from -55°C to 125°C, while the SDR1006-221KL operates from -40°C to 125°C. Applications requiring operation below -40°C must retain the PD104R-224K.

Physical Dimensions: The SDR1006-221KL has slightly larger width (9.80mm vs 8.79mm) and greater height (5.80mm vs 4.00mm). PCB layout and clearance verification is required before substitution.

Frequently Asked Questions (FAQ)

Q: Can the SDR1006-221KL replace the PD104R-224K in all applications?

A: Electrical substitution is valid for applications operating within -40°C to 125°C temperature range. Applications requiring operation below -40°C must use the PD104R-224K. Physical dimensions differ; PCB layout compatibility must be verified.

Q: What is the significance of the current rating difference between these parts?

A: The PD104R-224K is rated for 530 mA continuous current. The SDR1006-221KL provides 660 mA rating with 1.1 A saturation current. This higher rating provides additional design margin but does not alter the substitution validity for circuits designed for 530 mA operation.

Q: Are there differences in DC resistance that affect circuit performance?

A: The PD104R-224K specifies 720 mOhm Max DCR; the SDR1006-221KL specifies 730 mOhm Max DCR. This 10 mOhm difference is negligible for most applications and does not materially affect power dissipation or thermal performance.

Q: What physical considerations apply when substituting these parts?

A: The SDR1006-221KL is 0.082" (2.08mm) wider and 0.071" (1.80mm) taller than the PD104R-224K. PCB footprint, component clearance, and thermal management layout must be evaluated before substitution.

Q: Do both parts meet the same compliance standards?

A: Both the PD104R-224K and SDR1006-221KL are ROHS3 compliant with MSL rating of 1 (Unlimited). Both carry REACH Unaffected status and EAR99 ECCN classification.

Q: What is the inductance test frequency for these parts?

A: Both parts are tested at 1 kHz for inductance measurement, ensuring consistent specification basis for comparison.
