BFC241774704 Equivalent & Substitute Parts

Part Overview

The BFC241774704 is a 0.47 µF film capacitor manufactured by Vishay Beyschlag/Draloric/BC Components, rated for 160V DC operation with ±2% tolerance. This polypropylene metallized radial capacitor is designed for high-frequency and switching applications. The part maintains Active product status with 944 units currently in stock.

Substitute parts become necessary when the primary component experiences supply constraints, extended lead times, or when design requirements permit operation within broader electrical specifications. The B32652A3474J000 from EPCOS - TDK Electronics serves as a manufacturer-recommended alternative, offering enhanced voltage rating and expanded temperature range while maintaining core capacitance and dielectric properties.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BFC241774704 is determined by the following criteria:

Primary Matching Parameters:

• Capacitance value: 0.47 µF (exact match required)
• Dielectric material: Polypropylene (PP), Metallized (exact match required)
• Mounting type: Through Hole (exact match required)
• Package configuration: Radial (exact match required)
• Lead spacing: 0.591" (15.00mm) (exact match required)

Allowable Variation Parameters:

• Voltage rating: Equal to or greater than 160V DC
• Tolerance: Equal to or tighter than ±2%
• Operating temperature: Range must encompass or exceed -55°C ~ 85°C
• RoHS compliance: ROHS3 or equivalent

The B32652A3474J000 qualifies as a direct substitute based on matching all primary parameters while exceeding allowable variations in voltage rating (250V DC), tolerance (±5%), and operating temperature range (-55°C ~ 100°C).

Parameter Comparison

Engineering Selection Recommendations

Both the BFC241774704 and B32652A3474J000 maintain Active product status with ROHS3 compliance and REACH Unaffected designation, ensuring regulatory alignment for current applications.

The B32652A3474J000 substitute provides superior electrical headroom with 250V DC rating versus the 160V DC specification of the main part. This elevated voltage rating permits operation in circuits designed for the original specification without derating concerns. The extended operating temperature range to 100°C accommodates thermal environments beyond the primary part's 85°C maximum.

Physical dimensions increase marginally: length by 0.020" (0.50mm) and width by 0.059" (8.50mm), with height increasing by 0.039" (1.00mm). Lead spacing remains identical at 0.591" (15.00mm), ensuring PCB footprint compatibility. Tolerance relaxation from ±2% to ±5% may require circuit-level evaluation in applications with tight capacitance specifications.

The B32652A3474J000 carries AEC-Q200 automotive qualification, indicating suitability for automotive-grade reliability requirements. Selection between these parts depends on available inventory, tolerance requirements, and thermal operating conditions specific to the application.

Frequently Asked Questions (FAQ)

Q: Can the B32652A3474J000 be used as a direct replacement for the BFC241774704 on existing PCBs?

A: Yes, with physical space verification. Lead spacing is identical at 0.591" (15.00mm), ensuring electrical connectivity. However, the substitute is slightly larger: 0.709" L x 0.335" W versus 0.689" L x 0.276" W. Confirm available board space accommodates the increased footprint before substitution.

Q: What is the impact of the ±5% tolerance on the B32652A3474J000 compared to the ±2% tolerance of the BFC241774704?

A: The substitute permits greater capacitance variation within specification. For applications requiring precise capacitance values, measure the actual substitute component or evaluate circuit performance with the wider tolerance band. The 0.47 µF nominal value remains identical; only the acceptable deviation range expands.

Q: Does the higher 250V DC rating of the B32652A3474J000 affect circuit performance?

A: No adverse effects occur when a higher-rated capacitor operates below its maximum voltage specification. The 250V rating provides design margin and permits operation in circuits originally specified for 160V without performance degradation. This represents a conservative substitution approach.

Q: Are there thermal considerations when using the B32652A3474J000 in place of the BFC241774704?

A: The substitute operates to 100°C versus the original part's 85°C maximum. This extended range accommodates higher ambient or component temperatures without thermal derating. If the application operates below 85°C, both parts perform identically in thermal terms.

Q: What does AEC-Q200 qualification on the B32652A3474J000 indicate?

A: AEC-Q200 certification confirms the part meets automotive-grade reliability and quality standards. This qualification is beneficial for automotive applications but does not restrict use in non-automotive circuits. It indicates enhanced manufacturing controls and reliability testing.
