Substitute Part Grouping Explanation

Substitution eligibility for the ECQ-E2105KFZ is determined by strict equivalence across the following critical parameters:

• Capacitance value: 1 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage Rating - DC: 250V (exact match or higher required)
• Dielectric Material: Polyester, Metallized (exact match required)
• Operating Temperature Range: -40°C ~ 105°C (exact match or wider range acceptable)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial (exact match required)
• Physical dimensions and lead spacing: 0.728" L x 0.591" lead spacing (exact match required for PCB compatibility)
• Termination: PC Pins (exact match required)

The ECQ-E2105KF qualifies as a parametric equivalent based on full alignment with all critical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both ECQ-E2105KFZ and ECQ-E2105KF are Active products manufactured by Panasonic Electronic Components with identical ROHS3 compliance and REACH unaffected certification status. Selection between these parts should be based on inventory availability and lead time requirements, as electrical and mechanical specifications are equivalent. The ECQ-E2105KF currently maintains higher inventory levels (29,406 pcs vs. 1,063 pcs), making it suitable for high-volume procurement scenarios. Both parts satisfy identical regulatory and compliance requirements for deployment in general-purpose applications.

Frequently Asked Questions (FAQ)

Q: Can ECQ-E2105KF be used as a direct replacement for ECQ-E2105KFZ?

A: Yes. Both parts share identical capacitance (1 µF), tolerance (±10%), DC voltage rating (250V), dielectric material (polyester metallized), operating temperature range (-40°C ~ 105°C), mounting type (through hole), package configuration (radial), physical dimensions (0.728" L x 0.291" W), lead spacing (0.591"), and termination type (PC pins). PCB layout and circuit performance remain unchanged.

Q: What is the difference between ECQ-E2105KFZ and ECQ-E2105KF?

A: The ECQ-E2105KF includes an AC voltage rating specification (150V AC) not listed for the ECQ-E2105KFZ. All other electrical and mechanical parameters are identical. Both maintain Active product status and equivalent compliance certifications.

Q: Are there any physical compatibility concerns when substituting these parts?

A: No. Both parts feature identical radial package dimensions, lead spacing (0.591"), and PC pin termination. Direct PCB substitution is mechanically compatible without layout modifications.

Q: Which part should be selected for new designs?

A: Either part is suitable for new designs. Selection should prioritize the part with better availability and lead time performance. Both maintain equivalent Active product status and full regulatory compliance.

Q: Do these parts require different handling or storage procedures?

A: No. Both parts share identical moisture sensitivity classification (Not Applicable) and storage requirements as polyester film capacitors.
