ECQ-V1J824JM3 Equivalent & Substitute Parts

Part Overview

The ECQ-V1J824JM3 is a 0.82 µF film capacitor rated at 63V DC, manufactured by Panasonic Electronic Components in the ECQ-V series. This radial through-hole component uses polyester metallized-stacked dielectric technology and operates across a temperature range of -40°C to 105°C. The part is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ECQ-V1J824JM3 is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 0.82 µF (exact match required)
• Tolerance: ±5% (matching tolerance band)
• Voltage Rating (DC): 63V minimum (equal or higher acceptable)
• Dielectric Type: Polyester-based metallized film (functional equivalence)
• Mounting Configuration: Through-hole radial with 5.00mm lead spacing
• Termination Style: PC pins for PCB insertion

The substitute part B32529C0824J289 meets all these criteria. While it features an extended operating temperature range (-55°C to 125°C) and includes AC voltage rating (40V), these represent performance enhancements rather than deviations from the core electrical specification.

Engineering Selection Recommendations

The B32529C0824J289 is a direct functional equivalent for the obsolete ECQ-V1J824JM3. Selection of this substitute is justified on the following grounds:

• Electrical Equivalence: Identical capacitance (0.82 µF), tolerance (±5%), and DC voltage rating (63V) ensure circuit performance parity.
• Physical Compatibility: Matching radial through-hole configuration with 5.00mm lead spacing permits direct PCB footprint substitution without layout modification.
• Active Product Status: The B32529C0824J289 is an active product with confirmed inventory availability, ensuring long-term supply chain viability compared to the obsolete ECQ-V1J824JM3.
• Regulatory Compliance: ROHS3 compliance of the substitute part aligns with current environmental and manufacturing standards.
• Enhanced Operating Range: The extended temperature specification (-55°C to 125°C) of the substitute provides operational margin beyond the original part's range (-40°C to 105°C).

Frequently Asked Questions (FAQ)

Q: Can the B32529C0824J289 be used as a direct replacement without circuit redesign?

A: Yes. The substitute part matches the critical electrical parameters (capacitance, tolerance, DC voltage rating) and physical configuration (radial through-hole, 5.00mm lead spacing) of the original ECQ-V1J824JM3. Direct PCB substitution is permissible.

Q: What is the significance of the AC voltage rating on the substitute part?

A: The B32529C0824J289 includes an AC voltage rating of 40V, which the original part does not specify. This parameter is relevant only if the circuit applies AC voltage across the capacitor. For DC-only applications, this specification does not affect substitution validity.

Q: Does the extended operating temperature range of the substitute part create compatibility issues?

A: No. The substitute's operating range (-55°C to 125°C) encompasses the original part's range (-40°C to 105°C). Extended temperature capability represents a performance enhancement and does not introduce incompatibility.

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

A: The main part is specified with standard packaging, while the substitute (B32529C0824J289) is supplied in Tape & Box (TB) format. Both use identical radial through-hole configuration. Packaging format does not affect electrical or mechanical compatibility.

Q: Is ROHS3 compliance of the substitute part a requirement for substitution?

A: ROHS3 compliance of the substitute part aligns with current regulatory standards. If the original design was not subject to ROHS requirements, the substitute's compliance status does not create a barrier to substitution. Conversely, if ROHS compliance is mandated, the substitute's certification satisfies this requirement.
