PD104R-564K Equivalent & Substitute Parts

Part Overview

The PD104R-564K is a 560 µH unshielded drum core wirewound inductor manufactured by API Delevan Inc., designed for surface mount applications with a current rating of 320 mA and maximum DC resistance of 1.9Ohm. This component is classified as Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the specified parameter tolerances for this inductor category. The primary substitute identified is the SDR1006-561KL from Bourns Inc., which shares the same inductance value, tolerance, core material, and DC resistance specifications.

Key Parameters

Substitute Part Grouping Explanation

The SDR1006-561KL qualifies as a direct substitute for the PD104R-564K based on the following critical parameters:

Matching Electrical Specifications:

• Inductance: 560 µH (identical)
• Inductance Tolerance: ±10% (identical)
• DC Resistance: 1.9Ohm Max (identical)
• Core Material: Ferrite (identical)
• Shielding: Unshielded (identical)
• Inductance Test Frequency: 1 kHz (identical)

Compatible Mechanical Specifications:

• Mounting Type: Surface Mount (identical)
• Package Type: Nonstandard (identical)
• Packaging Format: Tape & Reel (TR) (identical)

Compliance Alignment:

• RoHS3 Compliant (both parts)
• REACH Unaffected (both parts)
• ECCN: EAR99 (both parts)
• MSL Rating: 1 (Unlimited) (both parts)

The SDR1006-561KL demonstrates a higher current saturation rating (660 mA vs. 320 mA) and extended frequency characteristics, which do not preclude substitution but represent enhanced performance margins.

Parameter Comparison

Engineering Selection Recommendations

Primary Consideration - Electrical Equivalence: The SDR1006-561KL maintains electrical equivalence to the PD104R-564K across all critical parameters: 560 µH inductance, ±10% tolerance, 1.9Ohm maximum DC resistance, and ferrite core construction. Both components are rated for 1 kHz inductance testing and operate within compatible frequency domains.

Current Rating Assessment: The SDR1006-561KL provides a 330 mA current rating versus the PD104R-564K's 320 mA rating, representing a 3.1% increase. The substitute's saturation current of 660 mA exceeds the main part's 320 mA specification, providing additional performance margin without introducing incompatibility.

Thermal Operating Range: The PD104R-564K operates across -55°C to 125°C, while the SDR1006-561KL operates across -40°C to 125°C. Applications requiring operation below -40°C must retain the PD104R-564K. Applications within the -40°C to 125°C range are compatible with the substitute.

Physical Footprint Differences: The SDR1006-561KL exhibits dimensional variations: width increases by 0.04" (1.01mm) and height increases by 0.071" (1.80mm). PCB layout verification is required to confirm clearance compatibility before substitution.

Compliance Status: Both components maintain identical RoHS3 compliance, REACH unaffected status, MSL 1 rating, and EAR99 ECCN classification. No regulatory barriers exist for substitution.

Product Status: Both components are classified as Active products with established supply availability. The SDR1006-561KL maintains higher inventory levels (10,299 pcs vs. 671 pcs), supporting supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the SDR1006-561KL directly replace the PD104R-564K in all applications?

A: Electrical substitution is valid for applications operating within -40°C to 125°C temperature range and where PCB layout accommodates the increased physical dimensions (0.04" wider, 0.071" taller). Applications requiring -55°C operation must retain the PD104R-564K.

Q: What are the key electrical parameters that define substitution eligibility?

A: Inductance value (560 µH), tolerance (±10%), DC resistance (1.9Ohm maximum), core material (ferrite), and shielding configuration (unshielded) must remain constant. Both parts meet these criteria.

Q: Are there frequency-dependent differences between these inductors?

A: The SDR1006-561KL provides specified Q factor (12 @ 796kHz) and self-resonant frequency (2.3MHz) data. The PD104R-564K does not provide these specifications. Both are tested at 1 kHz inductance measurement frequency.

Q: What physical constraints should be evaluated before substitution?

A: The SDR1006-561KL is 0.04" wider and 0.071" taller than the PD104R-564K. Verify PCB layout clearances, trace routing, and component proximity to confirm accommodation of these dimensional increases.

Q: Do both parts meet the same compliance standards?

A: Yes. Both components are RoHS3 compliant, REACH unaffected, MSL 1 rated, and classified as EAR99 under ECCN. No compliance barriers exist for substitution.

Q: Which part should be selected for new designs?

A: Selection depends on application-specific requirements. For thermal range requirements below -40°C, specify PD104R-564K. For general applications within -40°C to 125°C with higher current margin requirements, SDR1006-561KL is acceptable. Verify PCB layout compatibility for both options.

Q: Is packaging format identical between these parts?

A: Yes. Both components are supplied in Tape & Reel (TR) format with nonstandard package classification, supporting automated assembly processes identically.
