Key Parameters

Substitute Part Grouping Explanation

Substitution of the PVC105 is determined by the following critical parameters:

Capacitance Tolerance Band: The PVC105 operates within a ±10% tolerance window at 0.5 µF. Substitute parts must fall within the acceptable capacitance range of 0.45 µF to 0.55 µF to maintain circuit performance.

Voltage Rating: The 100V DC rating establishes the minimum voltage withstand requirement. Substitute parts must maintain or exceed this rating to ensure safe operation under specified conditions.

Dielectric Type: Polyester film dielectric is the baseline material specification. Metallized polyester variants are functionally equivalent within the same tolerance and voltage parameters.

Package Configuration: Through-hole radial mounting is required for mechanical compatibility with existing PCB layouts. Lead spacing and physical dimensions must accommodate the original footprint or allow for minor layout adjustments.

Compliance Standards: RoHS3 compliance and REACH unaffected status are mandatory for regulatory alignment.

The ECQ-E1564KF from Panasonic Electronic Components qualifies as a substitute based on these parameters.

Parameter Comparison

Engineering Selection Recommendations

The ECQ-E1564KF is qualified as a direct substitute for the PVC105 based on the following criteria:

Electrical Equivalence: Both components share identical 100V DC voltage ratings and ±10% tolerance specifications. The capacitance values of 0.5 µF and 0.56 µF fall within the same tolerance band, ensuring functional equivalence in general-purpose applications.

Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying current environmental and safety standards.

Physical Compatibility: Both components feature through-hole radial mounting with PC pin termination. The ECQ-E1564KF exhibits a more compact physical footprint (12.00mm x 5.50mm versus 15.20mm x 40.60mm) and reduced lead spacing (10.00mm versus 34.10mm), requiring PCB layout verification for mechanical fit.

Product Status: The ECQ-E1564KF maintains active product status with 2784 units in stock, providing supply continuity for the obsolete PVC105.

Temperature Consideration: The ECQ-E1564KF operating range (-40°C ~ 105°C) is narrower than the PVC105 (-55°C ~ 125°C). Applications requiring operation below -40°C or above 105°C require alternative sourcing.

Frequently Asked Questions (FAQ)

Q: Can the ECQ-E1564KF directly replace the PVC105 without circuit modification?

A: The ECQ-E1564KF is electrically equivalent within the specified tolerance and voltage parameters. However, the significantly different physical dimensions and lead spacing require PCB layout assessment. Direct socket substitution is not possible without mechanical adaptation.

Q: What is the capacitance tolerance relationship between 0.5 µF and 0.56 µF?

A: At ±10% tolerance, the PVC105 operates between 0.45 µF and 0.55 µF, while the ECQ-E1564KF operates between 0.504 µF and 0.616 µF. The 0.56 µF nominal value of the ECQ-E1564KF falls within the acceptable tolerance band of the PVC105 specification, ensuring functional compatibility in general-purpose applications.

Q: Are there temperature limitations when using the ECQ-E1564KF as a substitute?

A: Yes. The ECQ-E1564KF is rated for -40°C to 105°C operation, compared to the PVC105 range of -55°C to 125°C. Applications requiring operation outside the -40°C to 105°C window must use alternative components.

Q: What are the lead spacing differences, and do they affect compatibility?

A: The PVC105 has 1.343" (34.10mm) lead spacing, while the ECQ-E1564KF has 0.394" (10.00mm) lead spacing. This substantial difference requires PCB footprint modification. Original through-hole positions cannot accommodate the substitute without rework.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both the PVC105 and ECQ-E1564KF are ROHS3 compliant and REACH unaffected, satisfying current environmental and safety standards for new designs and legacy applications.

Q: What is the significance of metallized polyester versus standard polyester dielectric?

A: Metallized polyester dielectric in the ECQ-E1564KF provides equivalent electrical performance to the standard polyester in the PVC105 within the specified voltage and tolerance parameters. Both constructions are suitable for general-purpose applications.
