Key Parameters

Substitute Part Grouping Explanation

The P1330R-473K qualifies as a direct substitute for the P1330-473K based on matching electrical and mechanical parameters. Substitution eligibility is determined by the following critical parameters:

• Inductance value and tolerance: Both parts specify 47 µH ±10%
• Current ratings: Identical continuous current rating of 467 mA and saturation current of 246 mA
• DC resistance: Both rated at 792 mOhm Max
• Core material and shielding: Both utilize ferrite cores with unshielded construction
• Operating temperature range: Both rated for -55°C to 125°C
• Physical footprint: Identical dimensions of 0.313" × 0.115" × 0.145" Max
• Moisture sensitivity: Both classified as MSL 1 (Unlimited)
• Mounting technology: Both are surface mount components with identical package specifications

The P1330R-473K represents a design iteration of the P1330 series with improved RoHS compliance certification.

Parameter Comparison

Engineering Selection Recommendations

Both the P1330-473K and P1330R-473K are active production components with identical electrical and mechanical specifications. Selection between these parts depends on regulatory compliance requirements:

• P1330R-473K is the preferred choice for new designs and applications requiring ROHS3 compliance. This variant demonstrates improved environmental and material certification standards.
• P1330-473K remains suitable for existing production runs and applications where RoHS compliance is not a contractual or regulatory requirement. Higher inventory availability (649 pieces) supports immediate procurement.
• Both parts maintain REACH unaffected status and EAR99 export classification.

Frequently Asked Questions (FAQ)

Q: Can the P1330R-473K directly replace the P1330-473K in production? A: Yes. Both components share identical electrical parameters (inductance, current ratings, DC resistance) and mechanical footprint (dimensions and mounting type). Functional compatibility is complete. The distinction lies in RoHS certification status.

Q: What is the difference between these two inductors? A: The P1330R-473K incorporates ROHS3 compliance certification, while the P1330-473K is RoHS non-compliant. All other specifications—inductance value, current handling, physical size, temperature range, and packaging—are identical.

Q: Does the RoHS compliance difference affect electrical performance? A: No. RoHS status reflects material composition and manufacturing process compliance rather than electrical characteristics. Both parts deliver equivalent inductance, current ratings, and DC resistance.

Q: Are the physical dimensions and mounting identical? A: Yes. Both inductors use the same nonstandard surface mount package with dimensions of 0.313" L × 0.115" W × 0.145" H Max. They are compatible with identical PCB layouts and automated assembly processes.

Q: What is the moisture sensitivity level, and does it affect handling? A: Both parts are classified as MSL 1 (Unlimited), indicating no special moisture control measures are required during storage or assembly. They can be handled under standard warehouse conditions.

Q: How should I select between these parts for a new design? A: For applications subject to RoHS regulations or customer requirements mandating ROHS3 compliance, specify the P1330R-473K. For legacy systems or applications without compliance mandates, either part is suitable based on availability.
