Key Parameters

Substitute Part Grouping Explanation

Substitution of the PD105R-683K is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 68 µH at 1 kHz test frequency
• Inductance tolerance: ±10%
• Core type: Ferrite, unshielded drum core configuration
• Mounting: Surface mount technology
• Current rating: Minimum 1.08 A saturation capability

Secondary Compatibility Factors:

• DC resistance within acceptable operating limits
• Operating temperature range compatibility
• RoHS3 compliance and MSL rating
• Physical dimensions permitting board-level integration

The SDR1006-680KL from Bourns Inc. satisfies all primary matching criteria and maintains compatibility across secondary factors, qualifying it as a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The SDR1006-680KL represents the qualified substitute for the obsolete PD105R-683K based on the following engineering factors:

Electrical Equivalence: Both components maintain identical inductance values (68 µH) and tolerance specifications (±10%). The SDR1006-680KL provides superior saturation current performance (2 A versus 1.08 A), ensuring margin in current-handling capability. DC resistance values are within 10mOhm of each other, maintaining thermal performance parity.

Compliance and Availability: The SDR1006-680KL holds active product status with 5141 units in stock, contrasting with the obsolete PD105R-683K. Both components maintain ROHS3 compliance and unlimited moisture sensitivity ratings, satisfying regulatory requirements for current manufacturing environments.

Temperature Performance: The SDR1006-680KL operates across -40°C to 125°C, covering the upper temperature requirement of the original part. Applications requiring the full -55°C lower limit must evaluate thermal performance independently.

Packaging Consideration: Both components utilize nonstandard surface mount packages with comparable physical dimensions (9.80mm × 8.79mm versus 9.80mm × 9.80mm), permitting direct board-level substitution in most applications.

Frequently Asked Questions (FAQ)

Q: Can the SDR1006-680KL directly replace the PD105R-683K in existing designs?

A: Yes. Both components share identical inductance values, tolerance specifications, core materials, and shielding configurations. Physical dimensions are comparable, supporting direct board-level substitution. Verify that the operating temperature range of -40°C to 125°C satisfies application requirements.

Q: What are the key electrical differences between these parts?

A: The SDR1006-680KL provides higher saturation current (2 A versus 1.08 A) and marginally lower DC resistance (220mOhm versus 230mOhm). These differences represent performance improvements, not limitations, for the substitute part.

Q: Are there packaging differences that affect assembly?

A: Both components are surface mount devices in nonstandard packages. The SDR1006-680KL is supplied in Tape & Reel packaging, while the PD105R-683K packaging format is not specified. Verify reel compatibility with existing pick-and-place equipment.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both the PD105R-683K and SDR1006-680KL are ROHS3 compliant with MSL rating of 1 (Unlimited), satisfying current manufacturing and environmental standards.

Q: What is the lower operating temperature limit consideration?

A: The PD105R-683K operates to -55°C, while the SDR1006-680KL operates to -40°C. Applications requiring operation below -40°C must independently verify thermal performance or identify alternative substitutes with extended lower temperature ratings.
