Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BF014D0102K are qualified based on the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Capacitance value: 1000 pF (exact match required)
• Voltage rating: Minimum 63V DC (equal or higher acceptable)
• Tolerance: ±10% or tighter (±5% acceptable as improvement)
• Dielectric: Polyester metallized construction

Mechanical Compatibility Criteria:

• Mounting type: Through-hole radial configuration
• Lead spacing: 5.00mm to 5.08mm (minor variations acceptable within PCB layout tolerances)
• Height seated: 6.50mm maximum (standard for radial film capacitors)
• Termination: PC pins

Compliance Considerations:

• RoHS3 compliance preferred for new designs
• Operating temperature range: -55°C minimum to 100°C minimum

Both identified substitutes meet these criteria with minor dimensional variations that remain within standard PCB assembly tolerances.

Parameter Comparison

Engineering Selection Recommendations

MMK5102K63J01L4BULK (KEMET) provides direct electrical and mechanical equivalence to the BF014D0102K. This part maintains identical capacitance, voltage rating, tolerance, and operating temperature specifications. The 0.08mm reduction in length (7.20mm vs 7.50mm) and 0.08mm reduction in lead spacing (5.00mm vs 5.08mm) fall within standard PCB layout tolerances for radial film capacitors. KEMET's MMK series is actively manufactured and RoHS3 compliant, ensuring long-term availability and regulatory compliance for new designs.

B32529C0102J000 (EPCOS - TDK) offers enhanced specifications suitable for applications requiring improved performance margins. This part features tighter tolerance (±5% vs ±10%), extended operating temperature range to 125°C, and AEC-Q200 automotive qualification. The stacked metallized construction provides additional reliability for demanding environments. Dimensional compatibility is maintained with minor variations. This option is recommended for applications where enhanced reliability, automotive compliance, or tighter tolerance requirements are specified.

Both substitutes are actively produced and RoHS3 compliant, providing superior long-term availability compared to the obsolete BF014D0102K.

Frequently Asked Questions (FAQ)

Q: Can MMK5102K63J01L4BULK be used as a direct replacement for BF014D0102K?

A: Yes. Both parts share identical electrical specifications (1000 pF, ±10%, 63V DC, 40V AC) and mechanical configuration (radial through-hole, 6.50mm height, PC pins). The 0.08mm differences in length and lead spacing are within standard PCB assembly tolerances for radial film capacitors and do not require PCB redesign.

Q: What is the difference between the KEMET and EPCOS substitutes?

A: The KEMET MMK5102K63J01L4BULK provides direct electrical equivalence with identical tolerance and temperature range. The EPCOS B32529C0102J000 offers tighter tolerance (±5%), extended temperature range to 125°C, and AEC-Q200 automotive qualification. Both are electrically and mechanically compatible; selection depends on application requirements for tolerance and temperature performance.

Q: Are there any lead spacing compatibility concerns?

A: Lead spacing differences are 0.08mm (5.08mm original vs 5.00mm substitutes). This variation is within standard PCB manufacturing tolerances for through-hole radial components and does not require PCB layout modification.

Q: Which substitute is recommended for new designs?

A: Both substitutes are suitable for new designs. KEMET MMK5102K63J01L4BULK provides cost-effective direct equivalence. EPCOS B32529C0102J000 is recommended for applications requiring automotive qualification, extended temperature range, or tighter tolerance specifications.

Q: Are both substitutes RoHS compliant?

A: Yes. Both MMK5102K63J01L4BULK and B32529C0102J000 are ROHS3 compliant. The original BF014D0102K is non-compliant, making these substitutes necessary for regulatory compliance in new designs.
