Key Parameters

Substitute Part Grouping Explanation

Substitution of the ELJ-QF10NGF is determined by the following critical parameters:

• Inductance Value: 10 nH (exact match required)
• Inductance Tolerance: ±2% (matching tolerance specification)
• Package / Case: 0402 (1005 Metric) (physical and electrical compatibility)
• Shielding Type: Unshielded (functional equivalence)
• Current Rating: Minimum 320 mA (equal or greater capacity)
• DC Resistance: Maximum 410 mOhm (equal or lower resistance preferred)
• Operating Temperature Range: Minimum -40°C ~ 85°C coverage
• Moisture Sensitivity Level: 1 (Unlimited) or equivalent

The AISC-0402-10NG-T from Abracon LLC meets these substitution criteria with enhanced electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The AISC-0402-10NG-T qualifies as a direct substitute for the ELJ-QF10NGF based on matching inductance value, tolerance, package specification, and shielding configuration. The substitute part demonstrates superior electrical performance with 480 mA current rating (150% of original specification) and reduced DC resistance of 200 mOhm maximum (approximately 49% lower than the original). The extended operating temperature range of -40°C to 125°C provides additional thermal margin beyond the original -40°C to 85°C specification.

The AISC-0402-10NG-T carries active product status with ROHS3 compliance certification, ensuring long-term availability and regulatory alignment. Both components maintain identical moisture sensitivity classification and REACH compliance status.

Frequently Asked Questions (FAQ)

Q: Can the AISC-0402-10NG-T directly replace the ELJ-QF10NGF in existing designs?

A: Yes. Both components share identical inductance value (10 nH), tolerance (±2%), package specification (0402 / 1005 Metric), and shielding configuration (unshielded). The substitute part meets or exceeds all critical electrical parameters of the original component.

Q: What are the differences in electrical performance between these parts?

A: The AISC-0402-10NG-T provides higher current rating (480 mA versus 320 mA) and lower DC resistance (200 mOhm maximum versus 410 mOhm maximum). These represent performance improvements that do not affect substitution compatibility.

Q: Are there any temperature range considerations for substitution?

A: The AISC-0402-10NG-T operates across -40°C to 125°C, extending the upper temperature limit by 40°C compared to the original -40°C to 85°C range. This provides additional thermal operating margin for applications requiring extended temperature performance.

Q: What is the physical compatibility between these components?

A: Both components use the 0402 (1005 Metric) surface mount package with identical footprint requirements. Physical dimensions are comparable, with the substitute part measuring 1.19mm L x 0.64mm W x 0.66mm H (seated) versus 1.00mm L x 0.50mm W x 0.55mm H (seated) for the original. These minor dimensional variations remain within standard PCB assembly tolerances.

Q: Is the AISC-0402-10NG-T available for procurement?

A: The AISC-0402-10NG-T carries active product status with 1094 pieces in current inventory, ensuring availability for new designs and production requirements. The original ELJ-QF10NGF is obsolete with limited remaining stock.
