Key Parameters

Substitute Part Grouping Explanation

Substitution of the BF014G0103J is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 10000 pF (exact match required)
• Tolerance: ±5% (electrical performance specification)
• Voltage Rating - DC: 250V (minimum requirement for circuit protection)
• Voltage Rating - AC: 160V (minimum requirement for circuit protection)
• Dielectric Material: Polyester, Metallized (chemical and electrical compatibility)
• Mounting Type: Through Hole (PCB assembly compatibility)
• Package / Case: Radial (physical form factor compatibility)
• Termination: PC Pins (solder connection compatibility)

The substitute part B32529C3103J000 meets all critical substitution criteria. Minor variations in physical dimensions and lead spacing remain within acceptable tolerances for through-hole radial film capacitors of this class.

Parameter Comparison

Engineering Selection Recommendations

The B32529C3103J000 is the qualified substitute for the obsolete BF014G0103J. Selection is based on the following engineering factors:

Product Status: The BF014G0103J is obsolete, while B32529C3103J000 is active and maintains current manufacturing support with 40730 units in stock versus 1026 units for the original part.

Compliance and Certifications: B32529C3103J000 carries ROHS3 compliance and AEC-Q200 automotive qualification, providing enhanced regulatory alignment for new designs and automotive applications. The original part is RoHS non-compliant.

Electrical Equivalence: Both components share identical capacitance, tolerance, and voltage ratings. The substitute provides an extended operating temperature range (-55°C to 125°C versus -55°C to 100°C), offering improved thermal margin.

Physical Compatibility: Lead spacing differs by 0.08mm (5.00mm versus 5.08mm) and length by 0.008" (7.30mm versus 7.50mm). These variations are within standard manufacturing tolerances for radial film capacitors and do not affect PCB footprint compatibility for through-hole applications.

Frequently Asked Questions (FAQ)

Q: Can B32529C3103J000 be used as a direct replacement for BF014G0103J?

A: Yes. Both components meet identical electrical specifications for capacitance, tolerance, voltage rating, and dielectric material. Physical dimensions are compatible with standard radial through-hole PCB layouts.

Q: What is the significance of the lead spacing difference?

A: The lead spacing difference of 0.08mm (5.00mm versus 5.08mm) is within standard manufacturing tolerance for radial film capacitors. PCB footprints designed for 0.200" (5.08mm) spacing accommodate the 0.197" (5.00mm) lead spacing of the substitute without functional impact.

Q: Does the extended temperature range of B32529C3103J000 affect compatibility?

A: No. The extended operating range (-55°C to 125°C) of the substitute is a superset of the original specification (-55°C to 100°C). This provides additional thermal margin without affecting electrical performance within the original operating envelope.

Q: What is the impact of RoHS compliance differences?

A: The substitute B32529C3103J000 is ROHS3 compliant, while the original is non-compliant. For new designs and applications subject to RoHS regulations, the substitute provides regulatory alignment. For legacy system support, both components remain functionally equivalent.

Q: Are there any application restrictions for the substitute?

A: B32529C3103J000 carries AEC-Q200 automotive qualification, making it suitable for automotive and industrial applications. The original BF014G0103J is designated for general-purpose use. The substitute is compatible with all general-purpose applications and extends to automotive environments.
