Key Parameters

Substitute Part Grouping Explanation

Substitution of the ECQ-U2A152ML is determined by the following critical parameters:

• Capacitance Value: 1500 pF (exact match required)
• Tolerance: ±20% (standard tolerance for film capacitors)
• Voltage Rating: Minimum 275V AC for direct replacement; higher ratings provide design margin
• Dielectric Type: Polyester or polypropylene metallized film acceptable for EMI/RFI suppression
• Mounting Configuration: Through-hole radial package with compatible lead spacing
• Temperature Range: Operating range must encompass -40°C to 100°C minimum
• Compliance: RoHS compliance required for modern applications

The BFC233623152 (Vishay Beyschlag/Draloric/BC Components) meets these substitution criteria with equivalent capacitance, tolerance, and mounting configuration, while offering enhanced voltage ratings and temperature performance.

Parameter Comparison

Engineering Selection Recommendations

The BFC233623152 serves as a functional equivalent for the obsolete ECQ-U2A152ML based on matching capacitance, tolerance, and X2 rating for EMI/RFI suppression applications. The substitute part provides superior voltage ratings (310V AC / 630V DC versus 275V AC) and extended temperature range (-55°C to 110°C versus -40°C to 100°C), offering enhanced design margin for demanding environments.

The transition from polyester to polypropylene dielectric in the substitute part maintains performance characteristics for suppression applications while improving long-term reliability. Both parts maintain RoHS compliance; the substitute achieves ROHS3 certification, meeting current regulatory requirements.

Lead spacing differs between the two parts (12.50mm versus 10.00mm), requiring PCB layout verification during substitution. Physical dimensions are reduced in the substitute part, facilitating integration into space-constrained designs.

Frequently Asked Questions (FAQ)

Q: Can the BFC233623152 directly replace the ECQ-U2A152ML without circuit modification?

A: The substitute part matches the critical electrical parameters (capacitance, tolerance, voltage rating, and X2 rating) required for EMI/RFI suppression. However, the reduced lead spacing (10.00mm versus 12.50mm) requires PCB layout adjustment. Verify hole spacing compatibility before implementation.

Q: What is the significance of the dielectric material change from polyester to polypropylene?

A: Both polyester and polypropylene metallized films are suitable for X2-rated EMI/RFI suppression applications. Polypropylene offers improved temperature stability and lower dissipation factor, enhancing performance in the extended operating range of the substitute part.

Q: Does the higher voltage rating of the BFC233623152 affect circuit performance?

A: Higher voltage ratings provide increased design margin without altering electrical performance at the specified 275V AC operating point. This characteristic is beneficial for applications subject to transient overvoltages or thermal stress.

Q: Are there packaging differences between the main part and substitute?

A: The main part is supplied in standard packaging, while the substitute (BFC233623152) is available in Tape & Reel (TR) format. Confirm packaging requirements for your procurement and assembly processes.

Q: What compliance certifications apply to both parts?

A: The ECQ-U2A152ML holds RoHS Compliant certification. The BFC233623152 achieves ROHS3 Compliant status, meeting current and future regulatory requirements for hazardous substance restrictions.
