ECW-F6273JLB Equivalent & Substitute Parts

Part Overview

The ECW-F6273JLB is a 0.027 µF film capacitor rated for 630V DC, manufactured by Panasonic Electronic Components. This radial through-hole component uses polypropylene (PP) metallized dielectric technology and operates across the temperature range of -40°C to 105°C. The part is Active status and ROHS3 compliant, making it suitable for high-frequency and switching applications. Substitute parts are identified when electrical specifications, mechanical compatibility, and regulatory compliance align with the original component requirements.

Substitute Part Grouping Explanation

Substitution eligibility for the ECW-F6273JLB is determined by strict alignment of the following critical parameters:

• Capacitance value: 0.027 µF (exact match required)
• Voltage rating: 630V DC (exact match required)
• Tolerance: ±5% (exact match required)
• Dielectric material: Polypropylene (PP), Metallized (exact match required)
• Operating temperature range: -40°C ~ 105°C (exact match required)
• Mounting type: Through Hole (exact match required)
• Package type: Radial (exact match required)
• Lead spacing: 0.295" (7.50mm) (exact match required)
• Termination: PC Pins (exact match required)
• Regulatory compliance: ROHS3 Compliant (exact match required)

The ECW-FD2J273JB meets all substitution criteria. Physical dimensions may vary within the radial package envelope, provided lead spacing and termination type remain constant and the component fits within the PCB layout constraints.

Parameter Comparison

Engineering Selection Recommendations

Both ECW-F6273JLB and ECW-FD2J273JB are Active status components manufactured by Panasonic Electronic Components with ROHS3 compliance and REACH unaffected status. Selection between these parts is based on PCB layout constraints and available board space.

The ECW-F6273JLB features a seated height of 0.571" (14.50mm), while the ECW-FD2J273JB has a more compact seated height of 0.390" (9.90mm). For applications with height restrictions or space-constrained layouts, the ECW-FD2J273JB provides a lower-profile alternative. For applications without height constraints, either part is electrically and mechanically equivalent.

Both parts carry identical electrical specifications, temperature ratings, and regulatory certifications. The choice between them depends solely on physical envelope requirements within the target PCB design.

Frequently Asked Questions (FAQ)

Q: Can ECW-FD2J273JB replace ECW-F6273JLB in my circuit?

A: Yes. Both parts are electrically identical with matching capacitance (0.027 µF), voltage rating (630V DC), tolerance (±5%), dielectric material (Polypropylene metallized), operating temperature range (-40°C ~ 105°C), and lead spacing (0.295" / 7.50mm). The primary difference is physical height. Verify that the lower profile of ECW-FD2J273JB (0.390" seated height) fits your PCB layout.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution requires exact matching of capacitance value, DC voltage rating, tolerance, dielectric material type, operating temperature range, mounting type (through hole), package type (radial), lead spacing, and termination style (PC pins). All these parameters are identical between the two parts.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry EAR99 ECCN classification. Regulatory status is identical.

Q: What is the physical difference between these two parts?

A: The ECW-FD2J273JB is more compact. It measures 0.496" L x 0.272" W with a maximum seated height of 0.390", compared to the ECW-F6273JLB at 0.512" L x 0.260" W with a maximum seated height of 0.571". Lead spacing remains constant at 0.295" (7.50mm) for both.

Q: Which part should I choose for a space-constrained application?

A: The ECW-FD2J273JB is the appropriate choice for height-restricted designs due to its lower profile (0.390" vs 0.571" seated height). Confirm that the slightly larger width (0.272" vs 0.260") does not conflict with your PCB layout before selection.
