ECQ-M2273KZ Equivalent & Substitute Parts

Part Overview

The ECQ-M2273KZ is a 0.027 µF film capacitor rated for 200V DC with ±10% tolerance, manufactured by Panasonic Electronic Components in the ECQ-M series. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement. The radial through-hole configuration with PC pins and 12.50mm lead spacing defines its mechanical footprint for circuit board integration.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the ECQ-M2273KZ is determined by the following mandatory parameters:

• Capacitance Value: 0.027 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage Rating - DC: Minimum 200V (equal or higher acceptable)
• Dielectric Material: Polyester (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial (exact match required)
• Termination: PC Pins (exact match required)

All three substitute parts meet these core electrical and mechanical requirements. Variations in lead spacing, physical dimensions, and operating temperature ranges are secondary considerations that depend on specific circuit board layout constraints and application thermal requirements.

Parameter Comparison

Engineering Selection Recommendations

ECQ-E2273KF (Panasonic): This substitute maintains manufacturer continuity with the original ECQ-M2273KZ. It is active in production with ROHS3 compliance and extended operating temperature range to 105°C. The 250V DC rating provides voltage margin above the 200V requirement. Lead spacing reduction from 12.50mm to 7.50mm requires circuit board layout verification.

BFC237141273 (Vishay Beyschlag): This substitute offers the widest operating temperature range (-55°C ~ 105°C) and ROHS3 compliance. The MKT371 series provides long-life characteristics. Lead spacing of 7.62mm is comparable to the ECQ-E2273KF. Physical dimensions are the most compact among substitutes.

DME2S27K-F (Cornell Dubilier): This substitute provides the highest operating temperature capability (-55°C ~ 125°C) and ROHS3 compliance. Lead spacing of 7.50mm matches the ECQ-E2273KF. Physical dimensions are slightly larger. REACH unaffected status is documented.

All three substitutes exceed the original 200V DC rating at 250V, providing design margin. Selection depends on circuit board layout constraints related to lead spacing and physical dimensions, as well as application thermal requirements.

Frequently Asked Questions (FAQ)

Q: Can ECQ-E2273KF, BFC237141273, or DME2S27K-F be used directly in place of ECQ-M2273KZ?

A: Electrical substitution is valid based on matching capacitance (0.027 µF), tolerance (±10%), dielectric material (polyester), and voltage rating (all rated ≥200V DC). However, mechanical substitution requires circuit board layout verification due to lead spacing differences. The original ECQ-M2273KZ has 12.50mm lead spacing, while all substitutes have 7.50mm or 7.62mm spacing.

Q: What is the impact of lead spacing reduction from 12.50mm to 7.50mm?

A: Lead spacing reduction affects circuit board hole pattern and component placement. Existing PCB designs with 12.50mm hole spacing cannot accommodate 7.50mm or 7.62mm lead spacing without board redesign. New designs can utilize the smaller spacing for improved board density.

Q: Are all substitutes RoHS compliant?

A: Yes. ECQ-E2273KF, BFC237141273, and DME2S27K-F are all ROHS3 compliant. The original ECQ-M2273KZ RoHS status is not specified in available documentation.

Q: Which substitute has the best temperature performance?

A: DME2S27K-F offers the highest operating temperature range at -55°C ~ 125°C, compared to -40°C ~ 85°C for the original part. ECQ-E2273KF and BFC237141273 both reach 105°C maximum.

Q: Do the substitutes have different voltage ratings?

A: All substitutes are rated for 250V DC, which exceeds the original 200V DC requirement. This provides additional voltage margin. AC voltage ratings vary: ECQ-E2273KF (150V AC), BFC237141273 (160V AC), and DME2S27K-F (160V AC).

Q: What is the difference between standard polyester and metallized polyester dielectric?

A: The original ECQ-M2273KZ uses standard polyester dielectric. All substitutes use metallized polyester dielectric, which provides self-healing properties and improved reliability characteristics while maintaining the same capacitance value and tolerance.
