Substitute Part Grouping Explanation

Substitution eligibility for the B41888C8687M003 is determined by the following critical parameters:

  • Capacitance value: 680 µF (exact match required)
  • Voltage rating: 63 V (exact match required)
  • Tolerance: ±20% (exact match required)
  • Package configuration: Radial, can format with through-hole mounting
  • Lead spacing: 0.197" (5.00 mm) (exact match required)
  • Operating temperature range: -55°C to 105°C (minimum requirement)
  • Polarization: Polar (exact match required)
  • Automotive qualification: AEC-Q200 certified
  • RoHS compliance: ROHS3 compliant

The EEU-FC1J681L from Panasonic Electronic Components satisfies all substitution criteria. Both parts share identical electrical specifications, mechanical dimensions, and regulatory compliance requirements.

Engineering Selection Recommendations

The EEU-FC1J681L is a direct functional equivalent for the obsolete B41888C8687M003. Both components meet identical electrical and mechanical specifications required for automotive applications. The Panasonic part carries active product status with established supply availability, making it the appropriate selection for replacement applications.

The EEU-FC1J681L demonstrates lower impedance (47 mOhms versus 65 mOhms) and reduced physical height (35.00 mm versus 42.00 mm), both favorable characteristics that do not compromise compatibility. Both parts maintain ROHS3 compliance and AEC-Q200 automotive qualification.

Frequently Asked Questions (FAQ)

Q: Can the EEU-FC1J681L be used as a direct replacement for the B41888C8687M003?

A: Yes. Both components share identical capacitance (680 µF), voltage rating (63 V), tolerance (±20%), lead spacing (5.00 mm), and package configuration (radial, can, through-hole). Both are AEC-Q200 qualified and ROHS3 compliant.

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

A: The EEU-FC1J681L has a maximum seated height of 35.00 mm compared to 42.00 mm for the B41888C8687M003. The diameter remains identical at 12.50 mm. This dimensional difference must be evaluated against available PCB clearance in the target application.

Q: Are there differences in electrical performance between these capacitors?

A: The EEU-FC1J681L exhibits lower impedance (47 mOhms at 100 kHz) compared to the B41888C8687M003 (65 mOhms at 10 kHz). This represents improved high-frequency performance characteristics. Both parts operate across the identical temperature range (-55°C to 105°C).

Q: What is the product status of each part?

A: The B41888C8687M003 is obsolete. The EEU-FC1J681L is active and maintains current manufacturing and supply availability.

Q: Are both parts suitable for automotive applications?

A: Yes. Both components carry AEC-Q200 qualification, confirming suitability for automotive environments and reliability requirements.
