PD104R-563K Equivalent & Substitute Parts
Part Overview
The PD104R-563K is a 56 µH unshielded drum core wirewound inductor manufactured by API Delevan Inc., designed for surface mount applications. This component operates at 1.01 A rated current with 200 mOhm DC resistance and is specified for operation across -55°C to 125°C. The part maintains Active product status and is RoHS3 compliant. Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity for applications requiring 56 µH inductance in nonstandard SMD packages.

Substitute Part Grouping Explanation
Substitution eligibility for the PD104R-563K is determined by the following critical parameters:
Primary Matching Criteria:
- Inductance value: 56 µH (within ±10% tolerance specification)
- Core type: Ferrite drum core, wirewound construction
- Shielding configuration: Unshielded
- Mounting technology: Surface mount, nonstandard package
- Inductance test frequency: 1 kHz
Secondary Compatibility Criteria:
- Current rating: Substitute must equal or exceed 1.01 A
- DC resistance: Substitute must not exceed 200 mOhm significantly
- Operating temperature range: Substitute must cover or exceed -55°C to 125°C
- Regulatory compliance: RoHS3 and REACH status alignment
The SDR1006-560KL from Bourns Inc. satisfies all primary matching criteria and demonstrates superior performance in secondary parameters, including higher current saturation (2.1 A vs. 1.01 A) and lower maximum DC resistance (190 mOhm vs. 200 mOhm).

Engineering Selection Recommendations
PD104R-563K Selection Criteria:
- Applications requiring extended low-temperature operation below -40°C
- Designs where the -55°C minimum operating temperature is specified
- Existing inventory or supply chain established with API Delevan Inc.
- Active product status ensures continued availability and support
SDR1006-560KL Selection Criteria:
- Applications operating within -40°C to 125°C range
- Designs benefiting from lower DC resistance (190 mOhm vs. 200 mOhm)
- Higher current saturation rating (2.1 A) provides additional design margin
- Bourns Inc. manufacturing and supply chain preference
- Active product status with established inventory levels
Both parts maintain RoHS3 compliance and REACH unaffected status, supporting regulatory requirements for commercial and industrial applications. Selection between these parts depends on operating temperature requirements and supply chain considerations rather than functional performance within the specified temperature range.
Frequently Asked Questions (FAQ)
Q: Can SDR1006-560KL replace PD104R-563K in all applications?
A: SDR1006-560KL is functionally compatible for applications operating within -40°C to 125°C. Applications requiring operation below -40°C must use PD104R-563K, which is rated to -55°C.
Q: What is the significance of the DC resistance difference (200 mOhm vs. 190 mOhm)?
A: The SDR1006-560KL exhibits lower maximum DC resistance, resulting in reduced resistive losses and improved efficiency. This difference is within typical manufacturing tolerances and does not prevent substitution in standard applications.
Q: Are the physical dimensions compatible?
A: Physical dimensions differ between parts. PD104R-563K measures 0.386" L × 0.346" W × 0.157" H (9.80mm × 8.79mm × 4.00mm). SDR1006-560KL measures 0.386" L × 0.386" W × 0.228" H (9.80mm × 9.80mm × 5.80mm). PCB layout and clearance verification is required before substitution.
Q: Do both parts use identical inductance test frequencies?
A: Yes, both parts specify inductance measurement at 1 kHz, ensuring direct comparison of inductance values.
Q: What is the moisture sensitivity level for both parts?
A: Both PD104R-563K and SDR1006-560KL carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
Q: Are both parts available in Tape & Reel packaging?
A: Yes, both parts are supplied in Tape & Reel (TR) packaging suitable for automated assembly processes.
