Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PD104R-822M is determined by the following critical parameters:

Inductance Value: The substitute part must maintain 8.2 µH inductance within the specified ±20% tolerance band.

Current Rating: The substitute part must support the application's current requirements. The PD104R-822M is rated for 2.55 A continuous current. Substitute parts with equal or higher current ratings are acceptable.

DC Resistance: The substitute part's maximum DC resistance must not exceed 50 mOhm to maintain equivalent electrical performance and minimize power dissipation.

Core Type and Shielding: Both the main part and substitute must use ferrite drum core construction with unshielded configuration to ensure consistent electromagnetic behavior.

Mounting and Package: Surface mount technology with nonstandard package dimensions must be maintained for mechanical compatibility.

Compliance and Temperature Range: Substitute parts must maintain RoHS3 compliance and operate within the specified temperature range of -55°C to 125°C.

Parameter Comparison

Engineering Selection Recommendations

The SDR1006-8R2ML from Bourns Inc. qualifies as a direct substitute for the PD104R-822M based on matching electrical specifications and compliance requirements.

Electrical Equivalence: Both parts maintain identical 8.2 µH inductance with ±20% tolerance. The SDR1006-8R2ML provides a higher current rating of 3 A compared to the PD104R-822M's 2.55 A rating, offering improved headroom for current handling. The DC resistance of 48 mOhm in the substitute is lower than the 50 mOhm maximum of the main part, resulting in reduced power dissipation.

Compliance and Certifications: Both parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings, ensuring equivalent environmental and regulatory compliance.

Temperature Operating Range: The PD104R-822M operates from -55°C to 125°C, while the SDR1006-8R2ML operates from -40°C to 125°C. Applications requiring operation below -40°C must retain the original PD104R-822M. For applications within the -40°C to 125°C range, the substitute is acceptable.

Physical Compatibility: Both parts use nonstandard surface mount packages with ferrite drum core unshielded construction, maintaining mechanical and electromagnetic compatibility in circuit board layouts.

Frequently Asked Questions (FAQ)

Q: Can the SDR1006-8R2ML replace the PD104R-822M in all applications?

A: The SDR1006-8R2ML is electrically and mechanically compatible with the PD104R-822M for applications operating within the temperature range of -40°C to 125°C. Applications requiring operation below -40°C must use the original PD104R-822M, as the substitute's minimum operating temperature is -40°C.

Q: What are the key electrical differences between these two inductors?

A: Both inductors maintain 8.2 µH inductance with ±20% tolerance. The SDR1006-8R2ML has a higher current rating (3 A versus 2.55 A) and lower DC resistance (48 mOhm versus 50 mOhm maximum), making it electrically superior for current handling and power efficiency.

Q: Are the physical dimensions compatible for PCB layout?

A: Both parts use nonstandard surface mount packages. The PD104R-822M measures 0.386" L × 0.346" W × 0.157" H (9.80mm × 8.79mm × 4.00mm). The SDR1006-8R2ML measures 0.386" L × 0.386" W × 0.228" H (9.80mm × 9.80mm × 5.80mm). The substitute is slightly wider and taller. PCB layout compatibility must be verified for the specific application.

Q: Do both parts meet the same regulatory and environmental standards?

A: Yes. Both the PD104R-822M and SDR1006-8R2ML are ROHS3 compliant, carry MSL 1 (Unlimited) ratings, and are REACH unaffected. They meet equivalent regulatory and environmental standards.

Q: What is the inductance tolerance for both parts?

A: Both inductors maintain ±20% inductance tolerance, ensuring equivalent performance consistency across the specified tolerance band.

Q: Can I use the SDR1006-8R2ML if my application requires the -55°C minimum operating temperature?

A: No. The SDR1006-8R2ML has a minimum operating temperature of -40°C. Applications requiring operation at -55°C must use the original PD104R-822M.
