ECQ-B2273JF Equivalent & Substitute Parts

Part Overview

The ECQ-B2273JF is a 0.027 µF film capacitor rated for 200V DC operation with polyester dielectric material and radial through-hole mounting. This component is classified as obsolete, making substitute parts necessary for ongoing production and maintenance applications. The ECQ-B series represents an earlier generation of Panasonic film capacitors, and active alternatives within compatible electrical and mechanical parameters are available to ensure design continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ECQ-B2273JF is determined by the following critical parameters:

• Capacitance Value: Must remain 0.027 µF (no tolerance deviation acceptable for functional equivalence)
• Voltage Rating - DC: Substitute must meet or exceed 200V DC rating
• Tolerance: Must maintain ±5% specification
• Dielectric Material: Polyester-based construction required for electrical performance compatibility
• Mounting Type & Package: Through-hole radial configuration with 0.295" (7.50mm) lead spacing required for PCB compatibility
• Operating Temperature Range: Must support -40°C ~ 105°C minimum

The ECQ-E2273JF meets all substitution criteria. It maintains identical capacitance, tolerance, and lead spacing while providing enhanced voltage rating (250V DC) and improved dielectric construction (metallized polyester). The physical footprint is compatible with the original design, and the component is currently in active production status.

Engineering Selection Recommendations

The ECQ-E2273JF is the direct functional equivalent for ECQ-B2273JF applications. Selection is based on the following engineering factors:

Product Status: The ECQ-B2273JF is obsolete, while the ECQ-E2273JF is in active production. This ensures long-term component availability and supply chain stability.

Electrical Compatibility: The substitute maintains identical capacitance (0.027 µF) and tolerance (±5%), with a higher DC voltage rating (250V vs. 200V). This provides improved design margin without altering circuit performance.

Compliance Status: The ECQ-E2273JF is ROHS3 compliant, whereas the original part is RoHS non-compliant. For applications subject to RoHS regulations, the substitute is mandatory.

Physical Compatibility: Lead spacing (0.295" / 7.50mm) and radial through-hole configuration are identical, ensuring direct PCB footprint compatibility without layout modifications.

Dielectric Enhancement: The metallized polyester construction of the ECQ-E2273JF provides improved performance characteristics while maintaining electrical equivalence.

Frequently Asked Questions (FAQ)

Q: Can the ECQ-E2273JF be used as a direct replacement for the ECQ-B2273JF?

A: Yes. The ECQ-E2273JF is electrically and mechanically compatible. It maintains the same capacitance value, tolerance, lead spacing, and operating temperature range. The higher voltage rating and improved dielectric material provide enhanced performance without circuit modification.

Q: What is the difference in physical size between these parts?

A: The ECQ-E2273JF has a smaller footprint (10.30mm L x 4.40mm W, height 8.50mm) compared to the ECQ-B2273JF (11.00mm L x 6.50mm W, height 11.50mm). However, both maintain the same 0.295" (7.50mm) lead spacing, ensuring PCB compatibility.

Q: Does the higher voltage rating of the ECQ-E2273JF affect circuit operation?

A: No. A higher voltage rating does not alter electrical performance in the circuit. The 250V rating of the substitute provides additional design margin and reliability compared to the 200V original specification.

Q: Are there RoHS compliance implications?

A: Yes. The ECQ-B2273JF is RoHS non-compliant, while the ECQ-E2273JF is ROHS3 compliant. For applications requiring RoHS certification, the substitute is necessary.

Q: What is the lead spacing requirement for PCB layout?

A: Both parts require 0.295" (7.50mm) lead spacing. This specification is identical between the main part and substitute, allowing direct footprint reuse.

Q: Can the ECQ-E2273JF be used in AC applications?

A: The ECQ-E2273JF is rated for 150V AC operation. The original ECQ-B2273JF has no specified AC rating. If AC operation is required, the substitute's 150V AC rating must be verified against circuit requirements.
