Key Parameters

Substitute Part Grouping Explanation

Substitution for the ECQ-E1183KF is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 0.018 µF (exact match required)
• Tolerance: ±10% (matching tolerance band)
• Voltage Rating - DC: 100V minimum (equal or higher acceptable)
• Dielectric Type: Polyester, Metallized (same technology)
• Mounting Configuration: Through Hole, Radial (same physical interface)
• Termination Style: PC Pins (same lead type)
• Operating Temperature: Compatible range (-40°C ~ 105°C or broader)

The BFC237021183 from Vishay Beyschlag/Draloric/BC Components meets all substitution criteria and is classified as an active product with current availability.

Engineering Selection Recommendations

The BFC237021183 is the qualified substitute for ECQ-E1183KF applications. Selection is based on the following engineering factors:

Electrical Equivalence: Both components share identical capacitance (0.018 µF), tolerance (±10%), and DC voltage rating (100V). The substitute's broader operating temperature range (-55°C to 105°C versus -40°C to 105°C) provides enhanced thermal performance for extended environmental conditions.

Physical Compatibility: Lead spacing is compatible (5.00mm versus 5.08mm), permitting direct PCB mounting without layout modification. The substitute exhibits a smaller footprint and lower profile, which may provide space advantages in compact designs.

Product Status and Compliance: The BFC237021183 is an active product with current manufacturing and inventory availability. It carries ROHS3 compliance certification, meeting modern regulatory requirements for new designs and production runs.

Application Suitability: The substitute is rated for automotive applications with AEC-Q200 certification, indicating qualification for demanding operational environments. This certification extends reliability assurance beyond general-purpose applications.

Frequently Asked Questions (FAQ)

Q: Can the BFC237021183 be used as a direct replacement for ECQ-E1183KF?

A: Yes. Both components are electrically and mechanically equivalent across all critical parameters: 0.018 µF capacitance, ±10% tolerance, 100V DC rating, polyester metallized dielectric, through-hole radial configuration, and PC pin termination. Lead spacing is compatible for PCB mounting.

Q: What are the physical differences between these components?

A: The BFC237021183 has a smaller footprint (7.20mm x 2.50mm versus 7.80mm x 4.60mm) and lower seated height (6.50mm versus 8.70mm). These dimensional reductions may benefit space-constrained layouts while maintaining electrical performance.

Q: Does the substitute have better temperature performance?

A: The BFC237021183 operates across -55°C to 105°C, compared to the original part's -40°C to 105°C range. This extended lower temperature limit provides additional thermal margin for applications in cold environments.

Q: Is the substitute RoHS compliant?

A: Yes. The BFC237021183 is ROHS3 compliant, meeting current environmental and regulatory standards. The original ECQ-E1183KF compliance status is not specified in available documentation.

Q: What is the lead spacing difference, and does it affect PCB compatibility?

A: The original part has 5.00mm lead spacing; the substitute has 5.08mm spacing. This 0.08mm difference is within standard PCB tolerance and does not prevent direct mounting on existing through-hole layouts designed for the ECQ-E1183KF.

Q: Is the BFC237021183 suitable for automotive applications?

A: Yes. The substitute carries AEC-Q200 automotive qualification and is rated for automotive applications, making it suitable for demanding operational environments beyond general-purpose use.
