Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PD75R-154K are identified based on the following critical electrical and mechanical parameters:

Electrical Criteria:

• Inductance: 150 µH (±10% tolerance)
• Current Rating: Minimum 580 mA
• DC Resistance: Maximum 640 mOhm

Mechanical Criteria:

• Core Type: Ferrite, unshielded drum core, wirewound
• Mounting Type: Surface mount
• Package compatibility: Nonstandard case dimension tolerance

Compliance Criteria:

• RoHS3 compliance required
• REACH unaffected status

Parts meeting all specified electrical parameters with compatible mechanical configuration and regulatory compliance are classified as direct substitutes. Inductance frequency test standardized at 1 kHz ensures measurement consistency across all listed parts.

Engineering Selection Recommendations

ASPI-0705-151K-T (Abracon LLC): Active product status with ROHS3 compliance and unlimited moisture sensitivity rating. Electrical parameters (150 µH, ±10% tolerance, 580 mA) match specification. Operating temperature range of -40°C to 85°C is restricted compared to PD75R-154K. DC resistance identical at 640 mOhm maximum. Tape & Reel packaging provides procurement flexibility.

SDR0805-151KL (Bourns Inc.): Active product status with ROHS3 compliance and unlimited moisture sensitivity rating. Electrical parameters (150 µH, ±10% tolerance, 580 mA) meet specification. Operating temperature range of -40°C to 125°C matches extended temperature requirement of PD75R-154K. DC resistance of 680 mOhm is within acceptable tolerance of the original 640 mOhm maximum. Higher saturation current (850 mA) provides design margin. Available in Cut Tape & Digi-Reel® packaging.

Both substitute parts maintain functional electrical equivalence. Selection between alternatives depends on application temperature requirements and packaging logistics.

Frequently Asked Questions (FAQ)

Q: Can ASPI-0705-151K-T replace PD75R-154K in all applications? A: ASPI-0705-151K-T provides electrical equivalence (150 µH, ±10%, 580 mA, 640 mOhm). Operating temperature range (-40°C to 85°C) restricts use in applications requiring the full -55°C to 125°C range of the original part.

Q: What is the difference in DC resistance between the substitute parts and the original? A: PD75R-154K and ASPI-0705-151K-T both specify 640 mOhm maximum DC resistance. SDR0805-151KL specifies 680 mOhm maximum, representing a 40 mOhm increase. This difference affects thermal performance and power dissipation in applications with sustained current loading.

Q: Are physical dimensions comparable between these parts? A: Physical dimensions vary within nonstandard package categories. PD75R-154K: 0.303" L × 0.272" W × 0.197" H; ASPI-0705-151K-T: 0.307" L × 0.276" W × 0.217" H; SDR0805-151KL: 0.307" L × 0.307" W × 0.209" H. PCB footprint compatibility must be verified for specific application layouts.

Q: Do all parts meet RoHS and regulatory requirements? A: All three parts (PD75R-154K, ASPI-0705-151K-T, SDR0805-151KL) are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes.

Q: What packaging options are available for procurement? A: PD75R-154K original specification does not specify standard packaging. ASPI-0705-151K-T is available in Tape & Reel (TR). SDR0805-151KL is available in Cut Tape (CT) & Digi-Reel®. Packaging selection affects handling, storage, and automatic assembly compatibility.
