Substitute Part Grouping Explanation

Substitution of the CD75NP-271KC is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match):

• Inductance value: 270 µH
• Inductance tolerance: ±10%
• Current rating: 420 mA minimum
• DC resistance: 1.11 Ohm maximum
• Core material: Ferrite
• Shielding configuration: Unshielded

Mechanical Parameters (Must Match):

• Mounting type: Surface Mount
• Package classification: Nonstandard
• Inductance test frequency: 1 kHz

Compliance Parameters (Must Match):

• RoHS3 compliance status
• Moisture sensitivity level: 1 (Unlimited)

The substitute part SDR0805-271KL meets all critical electrical and mechanical parameters while maintaining full regulatory compliance. Substitute parts must not deviate from specified inductance, current rating, DC resistance, or core material characteristics.

Frequently Asked Questions (FAQ)

Q: Can SDR0805-271KL replace CD75NP-271KC in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent across all critical parameters: 270 µH inductance, ±10% tolerance, 420 mA current rating, 1.11 Ohm maximum DC resistance, ferrite core, unshielded configuration, and surface mount packaging. Both are ROHS3 compliant with MSL 1 rating.

Q: What are the physical dimension differences between these parts?

A: CD75NP-271KC dimensions are 0.307" L x 0.276" W x 0.217" H (7.80mm x 7.00mm x 5.50mm). SDR0805-271KL dimensions are 0.307" L x 0.307" W x 0.209" H (7.80mm x 7.80mm x 5.30mm). The width dimension differs by 0.031" (0.80mm), and height differs by 0.008" (0.20mm). PCB layout verification is required before substitution.

Q: Does the substitute part offer any performance advantages?

A: SDR0805-271KL provides an extended operating temperature range of -40°C to 125°C compared to -40°C to 100°C for the CD75NP-271KC. This additional thermal margin may benefit applications with elevated ambient conditions. Both parts maintain identical electrical specifications at rated conditions.

Q: Are there any compliance or certification differences?

A: Both parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. SDR0805-271KL carries additional REACH Unaffected status. Both parts are classified under ECCN EAR99 and HTSUS 8504.50.4000.

Q: What is the saturation current specification for these parts?

A: CD75NP-271KC saturation current is not specified in available data. SDR0805-271KL saturation current is 660 mA, which exceeds the 420 mA rated current by 57%. This specification is provided for reference only and does not affect substitution eligibility.
