Key Parameters

Substitute Part Grouping Explanation

Substitution of the ECQ-V1154JM is determined by the following critical parameters:

• Capacitance Value: 0.15 µF (exact match required)
• Tolerance: ±5% (exact match required)
• Voltage Rating - DC: 100V (minimum requirement; higher ratings are acceptable)
• Dielectric Material: Polyester-based metallized film (functionally equivalent materials acceptable)
• Mounting Type: Through Hole radial configuration
• Lead Spacing: 0.295" (7.50mm) (mechanical compatibility requirement)
• Termination: PC Pins

The substitute part B32520C1154J000 meets all critical substitution criteria. While it exhibits differences in physical dimensions and expanded operating temperature range, these variations do not compromise functional equivalence for the specified electrical parameters.

Parameter Comparison

Engineering Selection Recommendations

The B32520C1154J000 is a direct functional equivalent for the ECQ-V1154JM based on matching electrical specifications: identical capacitance (0.15 µF), tolerance (±5%), and DC voltage rating (100V). Both components utilize polyester-based metallized film dielectric technology and share identical lead spacing (7.50mm) and through-hole radial mounting configuration.

The substitute part offers the advantage of active product status, ensuring continued availability and supply chain stability. The B32520C1154J000 is ROHS3 compliant and carries AEC-Q200 automotive qualification, providing enhanced compliance documentation. The expanded operating temperature range (-55°C to 125°C) and higher maximum temperature rating provide additional thermal margin compared to the original part.

Physical dimensions differ slightly; the substitute is marginally smaller in length and height. These dimensional variations do not affect electrical performance or circuit board layout compatibility given the identical lead spacing specification.

Frequently Asked Questions (FAQ)

Q: Can the B32520C1154J000 be used as a direct replacement for the ECQ-V1154JM?

A: Yes. Both components share identical capacitance (0.15 µF), tolerance (±5%), DC voltage rating (100V), lead spacing (7.50mm), and through-hole radial mounting configuration. The substitute meets all electrical and mechanical requirements for direct substitution.

Q: What is the significance of the different operating temperature ranges?

A: The ECQ-V1154JM operates from -40°C to 105°C, while the B32520C1154J000 operates from -55°C to 125°C. The substitute provides extended temperature capability. If the application operates within the original part's temperature range, both components are functionally equivalent. If extended temperature operation is required, the substitute offers additional margin.

Q: Does the physical size difference affect circuit board compatibility?

A: No. The critical mechanical parameter for through-hole radial capacitors is lead spacing, which is identical at 0.295" (7.50mm) for both parts. The substitute is slightly smaller in overall dimensions but maintains the same footprint on the circuit board.

Q: What compliance advantages does the substitute offer?

A: The B32520C1154J000 is ROHS3 compliant and carries AEC-Q200 automotive qualification. The original ECQ-V1154JM does not specify these certifications. If regulatory compliance or automotive qualification is required, the substitute provides documented compliance status.

Q: Are there any electrical performance differences between these parts?

A: No. Both components are specified with identical capacitance, tolerance, and voltage rating. The dielectric material composition differs slightly (PET specification in the substitute), but both utilize polyester-based metallized film technology with equivalent electrical characteristics.
