ECQ-B1222JF Equivalent & Substitute Parts

Part Overview

The ECQ-B1222JF is a 2200 pF film capacitor rated at 100V DC with ±5% tolerance, manufactured by Panasonic Electronic Components. This radial through-hole component uses polyester dielectric material and operates across a temperature range of -40°C to 105°C. The part is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications requiring this capacitance and voltage specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the ECQ-B1222JF is determined by strict equivalence across the following electrical and mechanical parameters:

• Capacitance value: 2200 pF (exact match required)
• Tolerance: ±5% (exact match required)
• Voltage rating: 100V DC minimum (equal or higher acceptable)
• Dielectric type: Polyester-based film (metallized variants acceptable)
• Mounting configuration: Through-hole radial with 5.00mm lead spacing
• Termination: PC pins for PCB insertion

Two active substitute parts meet these criteria and are available in production quantities.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts satisfy the electrical and mechanical requirements for direct replacement of the ECQ-B1222JF:

168222J100A-F (Cornell Dubilier Electronics) is an active production part with ROHS3 compliance and extended operating temperature range (-55°C to 125°C). This part features metallized polyester dielectric and is rated for general-purpose applications with 907 units in stock.

B32529C1222J000 (EPCOS/TDK Electronics) is an active production part with ROHS3 compliance, extended operating temperature range (-55°C to 125°C), and AEC-Q200 automotive qualification. This part features metallized polyester with stacked construction and is rated for automotive, EMI, and RFI suppression applications with 4804 units in stock.

Selection between these substitutes depends on application requirements. The EPCOS/TDK part provides automotive-grade reliability and higher inventory availability. The CDE part offers equivalent electrical performance with general-purpose classification.

Frequently Asked Questions (FAQ)

Q: Can the 168222J100A-F or B32529C1222J000 be used as direct replacements for the ECQ-B1222JF?

A: Yes. Both parts match the critical electrical parameters (2200 pF, ±5%, 100V DC) and mechanical specifications (5.00mm lead spacing, radial through-hole configuration, PC pin termination). Physical dimensions are within acceptable tolerance for standard PCB footprints.

Q: What is the difference between the two substitute parts?

A: The primary differences are dielectric construction (metallized vs. metallized-stacked), temperature range capability, and application classification. The EPCOS/TDK part includes AEC-Q200 automotive qualification and higher stock availability. Both meet the electrical requirements for the original part.

Q: Are there any temperature operating range considerations?

A: The ECQ-B1222JF operates from -40°C to 105°C. Both substitute parts extend this range to -55°C to 125°C, providing broader environmental capability without compromising performance at the original specification limits.

Q: Do the substitute parts have different physical dimensions?

A: Minor dimensional variations exist. The ECQ-B1222JF measures 0.283" L × 0.118" W with 0.295" seated height. The 168222J100A-F measures 0.283" L × 0.098" W with 0.256" seated height. The B32529C1222J000 measures 0.287" L × 0.098" W with 0.256" seated height. These differences do not affect PCB compatibility for standard radial footprints with 5.00mm lead spacing.

Q: Are compliance certifications available for the substitute parts?

A: Both substitute parts are ROHS3 compliant and REACH unaffected. The B32529C1222J000 additionally carries AEC-Q200 automotive qualification, suitable for automotive and mission-critical applications.
