Key Parameters

Substitute Part Grouping Explanation

Substitution of the ECQ-M2153KZ is determined by the following critical parameters:

• Capacitance Value: Must match exactly at 0.015 µF
• Voltage Rating: Substitute must meet or exceed 200V DC rating
• Dielectric Material: Polyester-based construction required for electrical performance equivalence
• Mounting Configuration: Through-hole radial package mandatory for mechanical compatibility
• Tolerance: ±10% tolerance acceptable for general-purpose applications
• Termination Style: PC pin termination required for PCB compatibility

The ECQ-E2153KF qualifies as a direct substitute based on these parameters. It maintains identical capacitance and tolerance specifications while providing enhanced voltage rating (250V DC) and improved temperature operating range (-40°C to 105°C).

Parameter Comparison

Engineering Selection Recommendations

The ECQ-E2153KF is the qualified substitute for the obsolete ECQ-M2153KZ. Selection is based on the following engineering criteria:

Electrical Compatibility: The substitute maintains identical capacitance (0.015 µF) and tolerance (±10%), with a higher DC voltage rating (250V versus 200V), providing improved safety margin in the application circuit.

Product Status: The ECQ-M2153KZ is obsolete with limited inventory availability. The ECQ-E2153KF is active production status with substantial stock (5793 pcs), ensuring supply chain continuity.

Compliance: The ECQ-E2153KF achieves ROHS3 compliance, whereas the original part is non-compliant. This substitution aligns with modern regulatory requirements for electronic component procurement.

Thermal Performance: The substitute extends the operating temperature range to 105°C (versus 85°C), providing enhanced reliability in elevated-temperature environments.

Physical Considerations: Lead spacing differs between parts (0.295" versus 0.374"). PCB layout verification is required to confirm mechanical fit within the existing footprint.

Frequently Asked Questions (FAQ)

Q: Can the ECQ-E2153KF be used as a direct replacement for the ECQ-M2153KZ?

A: Yes, the ECQ-E2153KF is electrically equivalent for the specified application. Both parts share identical capacitance (0.015 µF) and tolerance (±10%). The substitute provides higher voltage rating (250V DC) and extended temperature range. Physical lead spacing differs (0.295" versus 0.374"), requiring PCB layout confirmation.

Q: What is the significance of the metallized polyester dielectric in the substitute?

A: The ECQ-E2153KF uses metallized polyester construction, which is a standard evolution of polyester film capacitor technology. This construction maintains electrical performance while enabling the higher voltage rating and improved temperature characteristics. Both parts function identically in general-purpose filtering and coupling applications.

Q: Does the higher voltage rating of the substitute affect circuit performance?

A: No. A higher voltage rating does not alter electrical performance in the application. The 250V rating of the substitute provides additional safety margin compared to the 200V requirement of the original part. The capacitance value and tolerance remain unchanged.

Q: Is the lead spacing difference a concern for PCB compatibility?

A: Lead spacing differs between the parts (ECQ-M2153KZ: 0.374" / 9.50mm; ECQ-E2153KF: 0.295" / 7.50mm). Physical fit must be verified against the existing PCB footprint. If the PCB is designed for the original 0.374" spacing, mechanical modification or PCB redesign may be necessary.

Q: What is the inventory status for each part?

A: The ECQ-M2153KZ (obsolete) has 934 pcs available. The ECQ-E2153KF (active) has 5793 pcs in stock, providing superior supply chain availability for ongoing production requirements.

Q: Are there any compliance differences between the parts?

A: Yes. The ECQ-M2153KZ is RoHS non-compliant. The ECQ-E2153KF is ROHS3 compliant and REACH unaffected, meeting current regulatory standards for electronic component procurement in regulated industries.
