Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAL213664391E3 is determined by strict equivalence in the following parameters:

• Capacitance value: 390 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Voltage rating: 10 V (exact match required)
• Polarization: Polar (exact match required)
• Lead spacing: 5.00 mm (exact match required)
• Package type: Radial, Can (exact match required)
• Mounting type: Through Hole (exact match required)

The ELXY100ELL391MJC5S from Chemi-Con meets all substitution criteria. This part maintains identical electrical specifications and mechanical compatibility while offering an extended lifetime rating of 5000 hours at 105°C compared to the original 4000 hours.

Parameter Comparison

Engineering Selection Recommendations

Both parts are active products with ROHS3 compliance. The ELXY100ELL391MJC5S offers extended operational lifetime (5000 hours versus 4000 hours at 105°C) while maintaining identical electrical and mechanical specifications. The height difference of 0.020" (0.50 mm) between seated positions is within typical PCB clearance tolerances for through-hole radial capacitors.

The Chemi-Con substitute carries AEC-Q200 automotive qualification, indicating suitability for automotive-grade applications. Selection between these parts depends on application requirements and supply chain considerations rather than technical performance limitations.

Frequently Asked Questions (FAQ)

Q: Can ELXY100ELL391MJC5S replace MAL213664391E3 on existing PCBs without modification?

A: Yes. Both parts share identical lead spacing (5.00 mm), diameter (10.00 mm), and through-hole mounting configuration. The height difference of 0.50 mm is negligible for standard PCB layouts.

Q: Are the electrical specifications identical between these parts?

A: Yes. Capacitance (390 µF), tolerance (±20%), voltage rating (10 V), operating temperature range (-55°C to 105°C), and polarization are identical. Both parts meet ROHS3 compliance requirements.

Q: What is the significance of the lifetime rating difference?

A: The ELXY100ELL391MJC5S provides 5000 hours at 105°C versus 4000 hours for the MAL213664391E3. This extended rating indicates longer operational life under thermal stress, relevant for applications with continuous high-temperature operation.

Q: Does the AEC-Q200 rating on the Chemi-Con part affect general purpose applications?

A: No. AEC-Q200 certification indicates automotive-grade qualification and does not restrict use in general purpose applications. The part remains fully compatible with non-automotive designs.

Q: Are there impedance or ripple current differences that affect circuit performance?

A: Both parts specify 120 mOhms impedance. Ripple current specifications differ due to measurement frequency differences but do not affect substitution eligibility for general purpose applications.
