Key Parameters

Substitute Part Grouping Explanation

Substitution of the AISC-0402-2N7J-T is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Inductance value: 2.7 nH
• Package / Case: 0402 (1005 Metric)
• Core type: Ceramic drum core, wirewound
• Shielding configuration: Unshielded
• Current rating: 640 mA minimum
• DC resistance: 120 mOhm maximum
• Operating temperature range: -40°C to 125°C minimum
• Mounting type: Surface mount

Acceptable Variation Parameters:

• Inductance tolerance: ±5% or ±10% (tighter tolerance acceptable)
• Q factor @ 250 MHz: 13 or higher (higher Q acceptable)
• Product status: Active preferred over obsolete

Substitute parts are grouped into two categories: direct manufacturer alternatives from Abracon LLC and parametric equivalents from alternative manufacturers (Pulse Electronics and Walsin Technology Corporation). All identified substitutes maintain full electrical and mechanical compatibility with the original part specification.

Parameter Comparison

Engineering Selection Recommendations

AISC-0402-2N7K-T (Abracon LLC)

This part is the primary substitute for the obsolete AISC-0402-2N7J-T. Both parts are manufactured by Abracon LLC within the same AISC-0402 series. The AISC-0402-2N7K-T is currently in active production status, ensuring long-term availability. The only electrical difference is inductance tolerance (±10% versus ±5%), which remains within acceptable substitution parameters. All other specifications, including current rating, DC resistance, package dimensions, operating temperature range, and compliance certifications (ROHS3, MSL 1), are identical. This part is the recommended first choice for direct replacement.

BWCS001207072N7J00 (Pulse Electronics)

This parametric equivalent from Pulse Electronics provides full electrical and mechanical compatibility with the original part. The BWCS001207072N7J00 maintains the ±5% inductance tolerance matching the original specification and offers improved Q factor performance (16 versus 13 at 250 MHz). The part is in active production with higher inventory availability (8,423 units). All critical parameters including inductance, current rating, DC resistance, package dimensions, operating temperature range, and compliance certifications are equivalent. Packaging is supplied as Tape & Reel (TR).

WLCW1005Z0J2N7TB (Walsin Technology Corporation)

This parametric equivalent from Walsin Technology Corporation is an alternative source for the 2.7 nH 0402 inductor specification. The WLCW1005Z0J2N7TB maintains ±5% inductance tolerance and provides Q factor of 16 at 250 MHz. The part is in active production status. All critical electrical and mechanical parameters match the original specification. Packaging is supplied as Tape & Reel (TR). RoHS and moisture sensitivity level specifications are not provided in the available data.

Selection Criteria:

For applications requiring the original Abracon LLC manufacturer source, select AISC-0402-2N7K-T. For applications where alternative manufacturers are acceptable and improved Q factor performance is beneficial, select either BWCS001207072N7J00 or WLCW1005Z0J2N7TB. All three substitutes are suitable for direct replacement in the original circuit application.

Frequently Asked Questions (FAQ)

Q: Can AISC-0402-2N7K-T be used as a direct replacement for AISC-0402-2N7J-T?

A: Yes. Both parts are manufactured by Abracon LLC with identical electrical and mechanical specifications except for inductance tolerance. The AISC-0402-2N7K-T has ±10% tolerance versus ±5% for the original part. Since the original part is obsolete, AISC-0402-2N7K-T is the recommended direct replacement from the same manufacturer.

Q: What is the difference between the Abracon and Pulse Electronics versions?

A: The AISC-0402-2N7K-T (Abracon) and BWCS001207072N7J00 (Pulse Electronics) are functionally equivalent. Both maintain 2.7 nH inductance, 640 mA current rating, 120 mOhm DC resistance, and 0402 package dimensions. The Pulse Electronics part offers higher Q factor (16 versus 13 at 250 MHz) and is supplied in Tape & Reel packaging. Selection depends on manufacturer preference and supply chain requirements.

Q: Are all substitute parts RoHS3 compliant?

A: AISC-0402-2N7K-T and BWCS001207072N7J00 are confirmed ROHS3 compliant. WLCW1005Z0J2N7TB RoHS compliance status is not specified in the available technical data.

Q: Can these parts be used interchangeably in production?

A: Yes, all three substitute parts meet the electrical and mechanical requirements for direct substitution. They share identical inductance values, current ratings, DC resistance specifications, package dimensions, and operating temperature ranges. Substitution is valid across all three alternatives.

Q: What is the significance of the Q factor difference between parts?

A: Q factor at 250 MHz is provided for reference. The original part has Q of 13, while BWCS001207072N7J00 and WLCW1005Z0J2N7TB both have Q of 16. Higher Q factor indicates lower losses at the test frequency. This difference does not affect substitution validity but may provide performance benefits in RF applications.

Q: Are there packaging differences between substitutes?

A: AISC-0402-2N7K-T packaging is not specified in the available data. BWCS001207072N7J00 and WLCW1005Z0J2N7TB are both supplied in Tape & Reel (TR) packaging. Verify packaging requirements for your specific assembly process.

Q: What is the moisture sensitivity level for all parts?

A: AISC-0402-2N7J-T and AISC-0402-2N7K-T are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. BWCS001207072N7J00 is also MSL 1. WLCW1005Z0J2N7TB moisture sensitivity level is not specified in the available data.

Q: Can I use AISC-0402-2N7K-T with ±10% tolerance where ±5% was originally specified?

A: The ±10% tolerance of AISC-0402-2N7K-T is acceptable for substitution purposes. The tolerance difference reflects manufacturing process variation and does not affect circuit functionality in applications where the original ±5% tolerance was not a critical design constraint. Verify tolerance requirements for your specific application.
