Substitute Part Grouping Explanation

Substitution of the obsolete 701014680 is based on strict electrical and mechanical parameter alignment within the WE-FLAT-I and WE-HCFA series families. The primary substitute, Würth Elektronik 78436432068, maintains identical inductance value (6.8 µH), inductance tolerance (±15%), DC resistance specification (1.1 mOhm), shielding configuration (shielded), operating temperature range (-40°C to 150°C), package dimensions (27.50 mm × 27.50 mm × 17.00 mm), and AEC-Q200 automotive qualification.

The substitute part demonstrates improved current handling capability (38 A versus 35 A) and higher saturation current (24 A versus 20 A), providing enhanced performance margin without compromising electrical compatibility. Both parts are wirewound inductors with nonstandard package configurations and identical inductance test frequency (100 kHz).

Key substitution criteria:

  • Inductance: 6.8 µH (exact match)
  • Inductance tolerance: ±15% (exact match)
  • DC resistance: 1.1 mOhm (exact match)
  • Shielding: Shielded (exact match)
  • Operating temperature: -40°C to 150°C (exact match)
  • Package dimensions: 27.50 mm × 27.50 mm × 17.00 mm (exact match)
  • AEC-Q200 compliance: Yes (exact match)
  • RoHS3 compliance: Yes (exact match)
