Substitute Part Grouping Explanation

Substitute components for the AISC-0402-12NJ-T are qualified based on the following critical parameters:

  • Inductance value: 12 nH with ±5% tolerance
  • Current rating: 640 mA minimum
  • DC resistance: 120mOhm maximum
  • Core material and shielding: Ceramic, unshielded drum core
  • Package format: 0402 (1005 Metric) surface mount
  • Frequency characteristics: Q factor of 26 @ 250MHz and self resonant frequency of 3.6GHz
  • Compliance: RoHS3 compliant, MSL 1 rating

The substitute part CW100505-12NJ from Bourns Inc. meets all specified electrical parameters and maintains identical inductance, current rating, DC resistance, and frequency performance. Both components are active products with equivalent compliance certifications.

Engineering Selection Recommendations

Both the AISC-0402-12NJ-T and CW100505-12NJ are active products with full RoHS3 compliance and unlimited moisture sensitivity ratings. The electrical specifications are identical across inductance, current rating, DC resistance, and frequency performance. The Bourns CW100505-12NJ offers an extended lower operating temperature limit of -55°C compared to the Abracon part's -40°C minimum, providing additional thermal margin for applications requiring operation in colder environments. Both components are suitable for direct substitution in surface mount applications requiring 12 nH inductance at 640 mA current levels.

Frequently Asked Questions (FAQ)

Q: Can the CW100505-12NJ replace the AISC-0402-12NJ-T in existing designs?

A: Yes. Both components share identical electrical specifications including inductance value, tolerance, current rating, DC resistance, and frequency characteristics. The 0402 (1005 Metric) package format is identical, enabling direct PCB footprint compatibility.

Q: What is the difference in physical dimensions between these parts?

A: The AISC-0402-12NJ-T measures 0.047" L x 0.025" W with a maximum seated height of 0.026". The CW100505-12NJ measures 0.039" L x 0.022" W with a maximum seated height of 0.024". Both fit the 0402 (1005 Metric) package specification, though the Bourns component is slightly more compact.

Q: Are there temperature range considerations for substitution?

A: The CW100505-12NJ operates from -55°C to 125°C, while the AISC-0402-12NJ-T operates from -40°C to 125°C. For applications requiring operation below -40°C, the Bourns component provides extended low-temperature capability.

Q: Do both parts meet the same compliance standards?

A: Yes. Both components are RoHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity ratings. Both are classified under ECCN EAR99 and HTSUS 8504.50.8000.

Q: What determines substitution eligibility for this inductor category?

A: Substitution is based on matching inductance value and tolerance, current rating, DC resistance, core material and shielding type, package format, and frequency performance characteristics. Compliance certifications and product status must also align.
