PD104R-223K Equivalent & Substitute Parts

Part Overview

The PD104R-223K is a 22 µH unshielded drum core wirewound inductor manufactured by API Delevan Inc., rated for 1.6 A continuous current with a maximum DC resistance of 90 mOhm. This surface mount component operates across the temperature range of -55°C to 125°C and is classified as Active product status with ROHS3 compliance. Substitute parts are identified when equivalent inductance values, compatible current ratings, and matching core materials are required for circuit redesign, component obsolescence mitigation, or inventory optimization in applications where the original part becomes unavailable or procurement constraints exist.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PD104R-223K is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 22 µH (tolerance range acceptable within ±10% to ±20%)
• Core material: Ferrite drum core, unshielded configuration
• Mounting type: Surface mount
• Current rating: Minimum 1.6 A continuous current capability
• DC resistance: Maximum 100 mOhm (allowing marginal increase from 90 mOhm specification)

Compliance Requirements:

• RoHS3 compliance mandatory
• Operating temperature range: Minimum -40°C to 125°C (acceptable; original part extends to -55°C)
• Moisture sensitivity level: MSL 1 (Unlimited)

The SDR1006-220ML from Bourns Inc. satisfies all primary matching criteria with equivalent inductance, ferrite core construction, and surface mount configuration. The substitute part provides higher current saturation (3.5 A versus 1.6 A) and improved continuous current rating (1.95 A versus 1.6 A), making it suitable for applications requiring the specified 22 µH inductance with compatible electrical performance.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (PD104R-223K): The PD104R-223K remains the preferred selection when the original specification is available and procurement lead times are acceptable. This part is Active status with established supply (929 pcs in stock), ROHS3 compliance, and operates across the extended temperature range of -55°C to 125°C. The ±10% inductance tolerance provides tighter specification control for applications requiring precise inductance values.

Substitute Part Selection (SDR1006-220ML): The SDR1006-220ML is suitable for applications where the PD104R-223K is unavailable or when higher current capability margins are required. This substitute maintains ROHS3 compliance and MSL 1 rating. The substitute part provides superior current handling (1.95 A continuous, 3.5 A saturation) compared to the original specification (1.6 A continuous and saturation). The operating temperature minimum of -40°C is acceptable for applications not requiring extended low-temperature operation below -40°C. The ±20% inductance tolerance is wider than the original part; circuit designs must accommodate this tolerance variance. Substitute inventory availability is higher (6700 pcs in stock), supporting rapid procurement requirements.

Compliance Verification: Both parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard manufacturing and storage protocols. REACH status is unaffected for both components.

Frequently Asked Questions (FAQ)

Q: Can the SDR1006-220ML directly replace the PD104R-223K in all applications?

A: The SDR1006-220ML is electrically compatible for applications where the PD104R-223K operates at or below 1.6 A continuous current. The substitute part's higher current rating (1.95 A) and saturation current (3.5 A) provide design margin. However, the operating temperature minimum differs: the substitute operates from -40°C while the original operates from -55°C. Applications requiring operation below -40°C must use the original PD104R-223K. The wider inductance tolerance (±20% versus ±10%) must be evaluated against circuit requirements.

Q: What is the impact of the 10 mOhm increase in DC resistance?

A: The SDR1006-220ML specifies 100 mOhm maximum DC resistance compared to 90 mOhm for the PD104R-223K. This 11% increase results in proportionally higher resistive losses in the inductor. For applications sensitive to power dissipation or thermal performance, this difference must be calculated into the circuit design. The impact is typically negligible in low-power applications but becomes significant in high-current or high-frequency switching applications.

Q: Are the physical dimensions compatible?

A: The PD104R-223K measures 0.386" L × 0.346" W × 0.157" H (9.80mm × 8.79mm × 4.00mm). The SDR1006-220ML measures 0.386" L × 0.386" W × 0.228" H (9.80mm × 9.80mm × 5.80mm). The length is identical, but the substitute is wider (9.80mm versus 8.79mm) and taller (5.80mm versus 4.00mm). PCB layout and component placement must accommodate these dimensional differences.

Q: What packaging differences exist between these parts?

A: The PD104R-223K is supplied in Tape & Reel (TR) packaging. The SDR1006-220ML is supplied in Cut Tape (CT) & Digi-Reel® packaging. Both formats are standard for surface mount component handling and are compatible with automated assembly equipment. Procurement and inventory management processes may differ based on packaging format.

Q: How do the inductance tolerances affect circuit design?

A: The PD104R-223K specifies ±10% inductance tolerance, resulting in a range of 19.8 µH to 24.2 µH. The SDR1006-220ML specifies ±20% tolerance, resulting in a range of 17.6 µH to 26.4 µH. Applications with tight inductance requirements (such as resonant circuits or precision filters) must account for this wider tolerance band when using the substitute part. Circuit simulations should include worst-case tolerance analysis.

Q: Are both parts suitable for high-frequency applications?

A: The SDR1006-220ML provides frequency performance data: self-resonant frequency of 13 MHz and Q of 25 at 2.52 MHz. The PD104R-223K does not specify these parameters. For applications operating above 1 MHz, the substitute part's frequency characteristics should be verified against circuit requirements. The unshielded configuration of both parts may introduce EMI considerations in high-frequency designs.
