Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ECQ-M4822KZ are identified based on the following core electrical and mechanical parameters:

Primary Matching Criteria:

• Capacitance value: 8200 pF (exact match required)
• Tolerance: ±10% (exact match required)
• Dielectric material: Polyester (same family)
• Mounting type: Through Hole Radial (same form factor)
• Termination: PC Pins (same connection type)

Allowable Variations:

• Voltage rating: Equal to or greater than 400V DC
• Operating temperature range: Equal to or exceeding -40°C to 85°C
• Physical dimensions: Minor variations acceptable if lead spacing and mounting compatibility are maintained
• Dielectric construction: Metallized polyester acceptable as functional equivalent

Two substitute parts meet these criteria and are listed below.

Parameter Comparison

Engineering Selection Recommendations

ECQ-E6822KF (Panasonic): This substitute offers identical capacitance and tolerance with elevated voltage rating (630V vs. 400V), providing design margin for overvoltage conditions. The extended operating temperature range (-40°C to 105°C) supports broader environmental applications. Metallized polyester construction improves reliability. Lead spacing increases from 9.50mm to 10.00mm, requiring PCB layout verification. RoHS3 compliance supports modern manufacturing standards. Product status is obsolete, limiting long-term availability.

BFC237051822 (Vishay): This substitute matches the 400V DC rating and ±10% tolerance with identical capacitance. Extended operating temperature range (-55°C to 105°C) and AC voltage rating (220V) provide additional design flexibility. Metallized polyester construction enhances performance. Significantly reduced lead spacing (5.08mm vs. 9.50mm) requires PCB redesign. Active product status ensures current availability and supply chain continuity. AEC-Q200 automotive qualification and RoHS3 compliance support regulated applications.

Frequently Asked Questions (FAQ)

Q: Can ECQ-E6822KF be used as a direct replacement for ECQ-M4822KZ?

A: Electrical substitution is valid. The 630V rating exceeds the 400V requirement, and capacitance and tolerance match exactly. However, lead spacing differs (10.00mm vs. 9.50mm), requiring PCB layout modification. Verify footprint compatibility before implementation.

Q: Is BFC237051822 suitable for the same circuit application?

A: Yes, electrically. Capacitance, tolerance, and DC voltage rating are identical. The 220V AC rating provides additional capability. However, lead spacing is significantly reduced (5.08mm vs. 9.50mm), necessitating PCB redesign. The smaller package footprint may offer space advantages in constrained layouts.

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

A: Metallized polyester construction provides self-healing properties and improved reliability compared to standard polyester film. Both materials are functionally equivalent for general-purpose applications. Metallized versions typically offer better performance in high-temperature and high-stress environments.

Q: Which substitute offers the best long-term availability?

A: BFC237051822 is the only active product among the three options. ECQ-M4822KZ and ECQ-E6822KF are both obsolete. For new designs or long-term production, BFC237051822 is recommended for supply chain continuity.

Q: Are there temperature range considerations for substitution?

A: The main part operates from -40°C to 85°C. Both substitutes support extended ranges (-40°C to 105°C and -55°C to 105°C respectively), providing margin for demanding thermal environments. No derating is required for the original operating range.

Q: What compliance certifications apply to each part?

A: ECQ-M4822KZ provides no RoHS or automotive certification data. ECQ-E6822KF is ROHS3 compliant. BFC237051822 is ROHS3 compliant and AEC-Q200 qualified for automotive applications. Select based on regulatory and application requirements.
