Substitute Part Grouping Explanation

Substitution of the AISC-1812H-5R6N-T is determined by the following critical parameters:

• Inductance Value: 5.6 µH (exact match required)
• Package / Case: 1812 (4532 Metric) surface mount (physical compatibility)
• Type: Drum core, wirewound construction (functional equivalence)
• Shielding: Unshielded (electromagnetic behavior match)
• Current Rating: Minimum 730 mA (operational capability)
• DC Resistance: Maximum 230mOhm (electrical performance)
• RoHS Compliance: ROHS3 Compliant (regulatory requirement)

The Würth Elektronik 7440450056 meets all substitution criteria with enhanced electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The Würth Elektronik 7440450056 is a direct functional substitute for the obsolete AISC-1812H-5R6N-T. Both components are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The substitute part provides improved electrical performance with lower DC resistance (180mOhm vs 230mOhm), higher current rating capability (1.18 A vs 730 mA), and an extended operating temperature range (-40°C to 125°C vs -25°C to 85°C). The tighter inductance tolerance (±20% vs ±30%) on the substitute part enhances circuit precision. Physical dimensions and package specifications are identical, ensuring direct PCB compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the Würth Elektronik 7440450056 be used as a direct replacement for the AISC-1812H-5R6N-T?

A: Yes. Both components share identical inductance values (5.6 µH), package specifications (1812 / 4532 Metric), and unshielded drum core construction. The substitute meets or exceeds all electrical requirements of the original part.

Q: What are the physical compatibility considerations?

A: Both parts use the 1812 (4532 Metric) surface mount package with identical footprints (0.177" L x 0.126" W / 4.50mm x 3.20mm). Maximum seated heights differ slightly (2.80mm vs 2.90mm), which does not affect standard PCB assembly processes.

Q: How do the electrical characteristics compare?

A: The substitute part provides superior electrical performance: lower DC resistance (180mOhm vs 230mOhm), higher current rating (1.18 A vs 730 mA), and higher self-resonant frequency (41MHz vs 33MHz). These improvements enhance circuit efficiency and thermal performance.

Q: Are there regulatory compliance differences?

A: Both parts are ROHS3 compliant, REACH unaffected, and carry identical ECCN (EAR99) and HTSUS (8504.50.8000) classifications. No compliance barriers exist for substitution.

Q: What is the inductance tolerance difference impact?

A: The substitute part features ±20% tolerance versus ±30% for the original. This tighter tolerance improves circuit predictability and reduces design margin requirements in precision applications.

Q: Does the extended temperature range of the substitute affect compatibility?

A: No. The substitute's operating range (-40°C to 125°C) encompasses the original specification (-25°C to 85°C). This provides additional operational flexibility without compatibility concerns.
