Core Electrical Parameters (Non-Negotiable):

• Capacitance: 0.15 µF (exact match required)
• Tolerance: ±5% (exact match required)
• Dielectric Material: Polypropylene (PP), Metallized (exact match required)

Mechanical Parameters (Non-Negotiable):

• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial (exact match required)
• Lead Spacing: 0.591" (15.00mm) (exact match required)
• Termination: PC Pins (exact match required)

Allowable Variation Parameters:

• Voltage Rating - DC: Equal to or greater than 250V
• Operating Temperature Range: Equal to or greater than -55°C to 105°C minimum
• Physical Dimensions: Minor variations acceptable within standard manufacturing tolerances
• Compliance Certifications: ROHS3 compliance required

Both substitute parts meet all core electrical and mechanical requirements while offering enhanced voltage ratings and automotive-grade certifications.

Parameter Comparison

Engineering Selection Recommendations

B32652A3154J000 Selection Criteria: This substitute maintains identical DC voltage rating (250V) and capacitance (0.15 µF) to the main part. It provides higher AC voltage rating (160V vs. 125V) and carries AEC-Q200 automotive qualification. Operating temperature maximum is reduced to 100°C. Physical dimensions are slightly smaller (18.00mm L x 5.00mm W vs. 17.50mm L x 6.00mm W). This part is suitable for applications where automotive-grade reliability is required and the 100°C upper temperature limit is acceptable.

B32652A4154J000 Selection Criteria: This substitute provides elevated DC voltage rating (400V vs. 250V) and higher AC voltage rating (200V vs. 125V) while maintaining identical capacitance and tolerance. It carries AEC-Q200 automotive qualification. Operating temperature maximum is reduced to 100°C. Physical dimensions are slightly larger (18.00mm L x 6.00mm W vs. 17.50mm L x 6.00mm W). This part is suitable for applications requiring higher voltage margin or where automotive-grade reliability is specified, provided the 100°C upper temperature limit is acceptable.

Both substitutes are ROHS3 compliant and maintain identical lead spacing and termination type, ensuring direct mechanical compatibility in standard through-hole PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can B32652A3154J000 or B32652A4154J000 be used as direct replacements for BFC238300154?

A: Yes, both parts meet the core substitution criteria. They maintain identical capacitance (0.15 µF), tolerance (±5%), dielectric material (polypropylene metallized), mounting type (through hole), package type (radial), lead spacing (15.00mm), and termination (PC pins). All three parts are ROHS3 compliant. Physical dimension variations are within acceptable manufacturing tolerances for radial film capacitors.

Q: What are the voltage differences between the three parts?

A: The main part BFC238300154 is rated 250V DC / 125V AC. B32652A3154J000 maintains 250V DC but increases AC rating to 160V. B32652A4154J000 increases both ratings to 400V DC / 200V AC. Higher voltage ratings provide additional safety margin in applications but do not affect compatibility in circuits designed for 250V DC operation.

Q: Are there temperature range differences?

A: Yes. The main part operates from -55°C to 105°C. Both substitutes operate from -55°C to 100°C. If your application requires operation above 100°C, the main part BFC238300154 is required.

Q: Do the substitutes have automotive certifications?

A: Yes. Both B32652A3154J000 and B32652A4154J000 carry AEC-Q200 automotive qualification. The main part BFC238300154 does not list this certification. If automotive-grade reliability is specified, the substitutes are preferred.

Q: Are there physical size differences?

A: Minor differences exist. BFC238300154 is 17.50mm L x 6.00mm W x 12.00mm H. B32652A3154J000 is 18.00mm L x 5.00mm W x 10.50mm H. B32652A4154J000 is 18.00mm L x 6.00mm W x 11.00mm H. These variations are within standard radial film capacitor tolerances and do not affect PCB layout compatibility given identical 15.00mm lead spacing.

Q: Which substitute should I select?

A: Selection depends on application requirements. If your circuit operates at or below 250V DC and does not exceed 100°C, either substitute is acceptable. If higher voltage margin is needed, select B32652A4154J000. If automotive certification is required, select either substitute. If operation above 100°C is necessary, use the main part BFC238300154.
