ECQ-V1474JM Equivalent & Substitute Parts

Part Overview

The ECQ-V1474JM is a 0.47 µF film capacitor rated for 100V DC, manufactured by Panasonic Electronic Components as part of the ECQ-V series. This component features a polyester metallized-stacked radial configuration with ±5% tolerance and is designed for general-purpose applications across an operating temperature range of -40°C to 105°C. The part is currently classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ECQ-V1474JM is determined by strict equivalence across the following critical parameters:

• Capacitance Value: Must be 0.47 µF (no tolerance deviation acceptable)
• Tolerance: Must be ±5% or tighter
• DC Voltage Rating: Must be 100V or higher
• Dielectric Type: Polyester-based metallized film construction
• Mounting Configuration: Through-hole radial package
• Lead Spacing: 0.295" (7.50mm) for PCB compatibility
• Termination: PC pins for standard through-hole assembly

The B32520C1474J000 from EPCOS - TDK Electronics meets all substitution criteria. While this part exhibits enhanced specifications in certain areas (lower operating temperature minimum, higher maximum temperature, smaller physical footprint), these represent improvements that maintain full backward compatibility with the original ECQ-V1474JM application requirements.

Parameter Comparison

Engineering Selection Recommendations

The B32520C1474J000 is a direct functional substitute for the obsolete ECQ-V1474JM. Selection should be based on the following factors:

Product Status: The ECQ-V1474JM is obsolete, whereas the B32520C1474J000 is active and in production. For new designs or ongoing procurement, the EPCOS - TDK part ensures long-term component availability.

Compliance & Certifications: The B32520C1474J000 carries AEC-Q200 automotive qualification and ROHS3 compliance, providing enhanced regulatory coverage for applications requiring automotive-grade reliability or environmental compliance. Both parts are REACH Unaffected and classified under ECCN EAR99.

Physical Compatibility: The B32520C1474J000 features a smaller footprint (10.00mm x 5.00mm versus 10.20mm x 6.80mm) and reduced seated height (10.50mm versus 11.00mm). These dimensional reductions are compatible with existing PCB layouts designed for the ECQ-V1474JM, as the critical lead spacing (7.50mm) remains unchanged.

Electrical Equivalence: Both parts deliver identical capacitance, tolerance, and DC voltage rating. The B32520C1474J000 provides an extended operating temperature range (-55°C to 125°C versus -40°C to 105°C), which represents a performance enhancement without introducing compatibility concerns.

Frequently Asked Questions (FAQ)

Q: Can the B32520C1474J000 be used as a direct replacement for the ECQ-V1474JM in existing assemblies?

A: Yes. The B32520C1474J000 meets all electrical and mechanical requirements for direct substitution. Identical capacitance (0.47 µF), tolerance (±5%), DC voltage rating (100V), and lead spacing (7.50mm) ensure PCB compatibility and circuit performance equivalence.

Q: What are the key differences between these two parts?

A: The primary differences are product status (ECQ-V1474JM is obsolete; B32520C1474J000 is active), physical dimensions (B32520C1474J000 is slightly smaller), operating temperature range (B32520C1474J000 supports -55°C to 125°C versus -40°C to 105°C), and certifications (B32520C1474J000 includes AEC-Q200 and ROHS3). These differences represent improvements that maintain full backward compatibility.

Q: Does the smaller footprint of the B32520C1474J000 affect PCB layout?

A: No. The critical parameter for PCB compatibility is lead spacing, which remains 0.295" (7.50mm) for both parts. The reduced length and width of the B32520C1474J000 provide layout flexibility without requiring PCB modifications.

Q: Are there any temperature-related limitations when substituting the B32520C1474J000?

A: No. The B32520C1474J000 supports the full operating temperature range of the ECQ-V1474JM (-40°C to 105°C) and extends beyond it (-55°C to 125°C). Applications operating within the original temperature specification face no thermal constraints.

Q: What certifications apply to the B32520C1474J000?

A: The B32520C1474J000 is AEC-Q200 qualified for automotive applications, ROHS3 compliant, REACH Unaffected, and classified as EAR99 for export control purposes. These certifications exceed the regulatory requirements of the obsolete ECQ-V1474JM.
