Key Parameters

Substitute Part Grouping Explanation

Substitution of the ECE-B1JV331S is determined by strict equivalence across the following electrical and mechanical parameters:

• Capacitance value: 330 µF (exact match required)
• Rated voltage: 63 V (minimum requirement; higher voltage ratings are acceptable)
• Tolerance: ±20% (acceptable range for general-purpose applications)
• Polarization: Polar (electrolytic capacitor type)
• Mounting type: Through Hole (axial lead configuration)
• Package style: Axial, Can (physical form factor)
• Operating temperature range: -40°C ~ 85°C (minimum coverage required)

The substitute part MAL202118331E3 from Vishay Beyschlag/Draloric/BC Components meets all these criteria and is classified as active product status, providing long-term availability and support.

Parameter Comparison

Engineering Selection Recommendations

The MAL202118331E3 is the direct substitute for the obsolete ECE-B1JV331S. Both components share identical electrical specifications for capacitance, voltage rating, tolerance, and operating temperature range, ensuring functional equivalence in circuit applications.

The Vishay part offers additional advantages: active product status ensures continued availability and supply chain stability, ROHS3 compliance supports modern manufacturing and environmental standards, and documented performance characteristics (409 mOhm ESR, 8000 Hrs @ 85°C lifetime) provide enhanced reliability data compared to the original Panasonic component.

Physical dimensions are compatible with standard through-hole axial lead spacing, allowing direct mechanical substitution without PCB redesign.

Frequently Asked Questions (FAQ)

Q: Can the MAL202118331E3 be used as a direct replacement for ECE-B1JV331S?

A: Yes. Both components have identical capacitance (330 µF), voltage rating (63 V), tolerance (±20%), polarization (polar), and mounting configuration (through-hole axial). The Vishay part is electrically and mechanically equivalent.

Q: What is the difference in ripple current specifications?

A: The ECE-B1JV331S specifies 450 mA at 120 Hz (low frequency), while the MAL202118331E3 specifies 854 mA at 10 kHz (high frequency). These measurements are taken at different frequencies and are not directly comparable. The Vishay part demonstrates higher ripple current capability at higher frequencies, which is typical for modern aluminum electrolytic capacitor designs.

Q: Does RoHS compliance affect substitution?

A: The ECE-B1JV331S is RoHS non-compliant, while the MAL202118331E3 is ROHS3 compliant. For new designs or systems requiring environmental compliance, the Vishay part is the appropriate choice. For legacy system repairs, either part functions identically from an electrical standpoint.

Q: Are the physical dimensions compatible?

A: The MAL202118331E3 dimensions are 0.492" diameter × 1.181" length (12.50mm × 30.00mm). These are standard axial can dimensions compatible with through-hole PCB layouts designed for the original Panasonic component. No mechanical modification is required.

Q: What is the ESR difference between the two parts?

A: The ECE-B1JV331S does not specify ESR. The MAL202118331E3 specifies 409 mOhm ESR. This documented specification in the Vishay part provides design engineers with precise impedance data for circuit analysis and thermal calculations.
