Key Parameters

Substitute Part Grouping Explanation

Substitution of the ECQ-V1333JM is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 0.033 µF (exact match required)
• Voltage Rating (DC): 100V minimum (equal or higher acceptable)
• Tolerance: ±5% (matching tolerance class)
• Dielectric Type: Polyester-based metallized film (functional equivalence)
• Mounting Configuration: Through-hole radial with 0.197" (5.00mm) lead spacing
• Termination Style: PC pins for PCB insertion

The B32529C1333J000 from EPCOS - TDK Electronics meets all substitution criteria. Both parts share identical capacitance, tolerance, voltage rating, dielectric material class, mounting type, and lead spacing. Physical dimensions differ slightly, but both conform to radial package geometry suitable for standard PCB footprints designed for 5.00mm lead spacing.

Parameter Comparison

Engineering Selection Recommendations

The B32529C1333J000 is a direct functional equivalent for the obsolete ECQ-V1333JM. Both components share identical electrical specifications: 0.033 µF capacitance, ±5% tolerance, and 100V DC rating. The substitute part is currently in active production status with ROHS3 compliance, ensuring long-term availability and regulatory alignment.

The B32529C1333J000 provides an extended operating temperature range (-55°C ~ 125°C versus -40°C ~ 105°C), which represents an operational advantage in temperature-critical applications. Physical dimensions are slightly reduced, with the substitute measuring 0.287" × 0.098" × 0.256" compared to the original 0.295" × 0.126" × 0.315". Both maintain the critical 0.197" (5.00mm) lead spacing, ensuring compatibility with existing PCB footprints.

For applications requiring the original ECQ-V1333JM specifications, the B32529C1333J000 is the recommended substitute based on electrical equivalence, active product status, and compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can the B32529C1333J000 be used as a direct replacement for the ECQ-V1333JM?

A: Yes. Both components have identical capacitance (0.033 µF), tolerance (±5%), and DC voltage rating (100V). Lead spacing is identical at 0.197" (5.00mm), and both use PC pin termination suitable for standard PCB mounting. The substitute is electrically and mechanically compatible.

Q: What are the physical dimension differences between these parts?

A: The B32529C1333J000 is slightly more compact: 0.287" L × 0.098" W × 0.256" H versus the ECQ-V1333JM at 0.295" L × 0.126" W × 0.315" H. The reduced footprint may provide layout advantages, but both conform to radial package geometry with matching lead spacing.

Q: Does the substitute part meet current compliance standards?

A: Yes. The B32529C1333J000 is ROHS3 compliant and carries REACH Unaffected status, meeting current regulatory requirements. The original ECQ-V1333JM is obsolete and no longer manufactured.

Q: Are there temperature rating differences?

A: The B32529C1333J000 operates across -55°C ~ 125°C, compared to the ECQ-V1333JM range of -40°C ~ 105°C. The substitute provides extended low-temperature and high-temperature performance, suitable for broader environmental applications.

Q: What is the lead spacing, and will it fit existing PCB footprints?

A: Both parts have 0.197" (5.00mm) lead spacing. PCB footprints designed for the ECQ-V1333JM will accommodate the B32529C1333J000 without modification.

Q: Is the dielectric material equivalent?

A: Both components use polyester-based metallized film dielectrics. The B32529C1333J000 specifies polyethylene terephthalate (PET), which is the chemical designation for polyester film, confirming material equivalence.
