P0402 Equivalent & Substitute Parts

Part Overview

The P0402 is an unshielded 2-coil inductor array manufactured by Pulse Electronics in the Tomcat series. This component provides dual inductance configurations: 161.8 µH when coils are connected in series and 40.5 µH when connected in parallel. The part is currently classified as obsolete, making identification of suitable substitute components essential for ongoing design support and production continuity.

Substitute Part Grouping Explanation

Substitution eligibility for the P0402 is determined by strict equivalence across the following critical parameters:

  • Dual-coil inductor array configuration with identical series and parallel inductance values (161.8 µH and 40.5 µH respectively)
  • Matching current ratings for both parallel (4.64 A) and series (1.77 A) configurations
  • Identical DC resistance specifications in both configurations
  • Unshielded construction
  • Surface mount technology with nonstandard package dimensions
  • Operating temperature range of -40°C to 130°C
  • Tolerance of ±20%

The P0402NL meets all these criteria and is classified as a direct substitute within the Tomcat series.

Engineering Selection Recommendations

The P0402NL is the direct equivalent substitute for the obsolete P0402. Both components are electrically and mechanically identical across all specified parameters. The primary distinction is product status: P0402NL is active and available, whereas P0402 is obsolete.

An additional consideration is regulatory compliance. The P0402NL carries ROHS3 certification, whereas the P0402 is RoHS non-compliant. For applications subject to RoHS requirements, P0402NL is the appropriate selection. For legacy systems without RoHS mandates, both parts remain functionally equivalent.

Frequently Asked Questions (FAQ)

Q: Can P0402NL be used as a direct replacement for P0402?

A: Yes. The P0402NL is electrically and mechanically identical to the P0402 across all specified parameters, including inductance values, current ratings, DC resistance, dimensions, and operating temperature range. Both components are unshielded 2-coil inductor arrays in the Tomcat series with nonstandard surface mount packages.

Q: What is the primary reason to transition from P0402 to P0402NL?

A: The P0402 is classified as obsolete. The P0402NL is the active production equivalent, ensuring continued availability and supply chain support. Additionally, P0402NL meets ROHS3 compliance requirements.

Q: Are there packaging differences between P0402 and P0402NL?

A: The P0402NL is supplied in tube packaging, whereas packaging information for P0402 is not specified. Both components have identical physical dimensions and mounting characteristics.

Q: Do the inductance values differ between configurations?

A: No. Both P0402 and P0402NL provide 40.5 µH in parallel configuration and 161.8 µH in series configuration. Current ratings and DC resistance values are identical in both configurations.

Q: Are there any compliance or certification differences?

A: The P0402NL is ROHS3 compliant, while the P0402 is RoHS non-compliant. Both are REACH unaffected and classified under ECCN EAR99. For applications requiring RoHS compliance, P0402NL is the appropriate selection.
