Substitute Part Grouping Explanation

Substitution eligibility for the BFC238320683 is determined by strict alignment of core electrical and mechanical parameters. The substitute part B32652A6683J000 qualifies based on the following criteria:

Matching Parameters (Required for Substitution):

• Capacitance: 0.068 µF (identical)
• Tolerance: ±5% (identical)
• Voltage Rating - DC: 630V (identical)
• Dielectric Material: Polypropylene (PP), Metallized (identical)
• Mounting Type: Through Hole (identical)
• Package / Case: Radial (identical)
• Lead Spacing: 0.591" (15.00mm) (identical)
• Termination: PC Pins (identical)
• RoHS Status: ROHS3 Compliant (identical)

Allowable Variations:

• Voltage Rating - AC: 220V (main) vs. 250V (substitute) — higher AC rating in substitute is acceptable
• Operating Temperature Range: -55°C ~ 105°C (main) vs. -55°C ~ 100°C (substitute) — substitute operates within main part range at minimum
• Physical Dimensions: Minor variations in length and height are acceptable provided lead spacing and mounting footprint remain identical
• Series Classification: Different manufacturer series designation does not affect electrical equivalence

Parameter Comparison

Engineering Selection Recommendations

Both the BFC238320683 and B32652A6683J000 maintain Active product status with full ROHS3 compliance and REACH unaffected designation. Selection between these parts should be based on:

Inventory Availability: The BFC238320683 has 1071 units in stock, while the B32652A6683J000 has 3491 units available. Higher substitute inventory may support extended production runs or rapid replenishment cycles.

Compliance Certifications: The B32652A6683J000 carries AEC-Q200 automotive qualification, providing additional assurance for applications requiring automotive-grade reliability. The BFC238320683 does not specify this certification.

Physical Footprint: The B32652A6683J000 features a lower seated height (0.433" vs. 0.532"), which may provide advantages in space-constrained PCB layouts while maintaining identical lead spacing for direct pin compatibility.

Temperature Operating Window: The BFC238320683 extends to 105°C maximum, providing 5°C additional headroom compared to the B32652A6683J000 at 100°C. Applications operating near thermal limits should prioritize the Vishay part.

Frequently Asked Questions (FAQ)

Q: Can B32652A6683J000 be used as a direct replacement for BFC238320683 on existing PCBs?

A: Yes. Both parts share identical lead spacing (15.00mm), termination type (PC Pins), and radial package configuration. The substitute's lower seated height (11.00mm vs. 13.50mm) presents no compatibility issues and may improve clearance in confined spaces.

Q: What is the significance of the different AC voltage ratings (220V vs. 250V)?

A: The substitute part B32652A6683J000 is rated for 250V AC, which is higher than the main part's 220V AC rating. This represents a conservative design margin and does not restrict substitution. Both parts maintain identical 630V DC ratings, which typically governs circuit performance in DC-biased applications.

Q: Are there any temperature-related limitations when substituting?

A: The B32652A6683J000 operates to 100°C maximum, compared to 105°C for the BFC238320683. For applications where sustained operation above 100°C is required, the Vishay part should be retained. For standard industrial and consumer applications operating below 100°C, the substitute is fully compatible.

Q: Does the AEC-Q200 certification on the substitute part affect compatibility?

A: No. AEC-Q200 certification on the B32652A6683J000 represents an additional qualification standard and does not create incompatibility. This certification may be beneficial for automotive or mission-critical applications requiring enhanced reliability documentation.

Q: How do the physical dimension differences impact PCB design?

A: The substitute part is slightly longer (18.00mm vs. 17.50mm) and narrower (6.00mm vs. 7.00mm) with a lower profile (11.00mm vs. 13.50mm). Lead spacing remains identical at 15.00mm, ensuring footprint compatibility. PCB layout requires no modification for direct substitution.
