Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 167334K63A-F are categorized into two functional groups based on electrical parameter compatibility:

Upgrade Category (Higher Voltage Rating): Parts B32520C1334J000 and B32520C1334K000 maintain the 0.33 µF capacitance and ±10% tolerance (B32520C1334K000) or ±5% tolerance (B32520C1334J000) while providing elevated 100V DC voltage rating. These components are suitable for applications requiring increased voltage margin or operating in higher voltage environments. Both parts feature automotive-grade AEC-Q200 certification and identical lead spacing (0.295") to the main part.

Similar Category (Matched Voltage Rating): Parts B32529C0334K000, B32529C0334K189, and B32529C0334K289 match the 63V DC voltage rating and ±10% tolerance of the main part. These components differ in physical dimensions and packaging format. B32529C0334K000 is supplied in Bulk packaging, while B32529C0334K189 and B32529C0334K289 are supplied in Cut Tape (CT) format. All three similar parts feature smaller physical dimensions (7.30mm x 3.00mm length x width, 5.00mm lead spacing) compared to the main part (10.50mm x 3.50mm length x width, 7.50mm lead spacing) and carry automotive-grade AEC-Q200 certification.

Substitution eligibility is determined by: matching capacitance value (0.33 µF), compatible tolerance specification (±10% or tighter), voltage rating equal to or exceeding application requirements, identical dielectric material classification (polyester metallized), matching operating temperature range (-55°C to 125°C), through-hole radial mounting configuration, and ROHS3 compliance status.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Identical Electrical Specifications): Part B32529C0334K000 provides direct electrical equivalence with matching 63V DC rating, ±10% tolerance, and identical operating temperature range. This part is suitable for applications where the main part is unavailable and physical space constraints do not restrict the smaller form factor (7.30mm x 3.00mm versus 10.50mm x 3.50mm). The reduced lead spacing (5.00mm versus 7.50mm) requires PCB layout verification. This part carries AEC-Q200 automotive certification and ROHS3 compliance.

For Packaging Format Flexibility: Parts B32529C0334K189 and B32529C0334K289 are electrically identical to B32529C0334K000 but supplied in Cut Tape (CT) packaging format. These parts are appropriate for high-volume automated assembly processes. Both maintain identical electrical parameters and physical dimensions. Selection between these variants depends on tape reel configuration and assembly equipment compatibility.

For Elevated Voltage Applications: Parts B32520C1334K000 and B32520C1334J000 provide 100V DC voltage rating, representing a 37% increase over the main part specification. B32520C1334K000 maintains ±10% tolerance matching the main part, while B32520C1334J000 offers improved ±5% tolerance. These parts are suitable for applications requiring increased voltage margin or operating in higher voltage environments. Physical dimensions are comparable (10.00mm x 4.00mm versus 10.50mm x 3.50mm), with identical 7.50mm lead spacing. Both parts carry AEC-Q200 automotive certification and ROHS3 compliance. The increased height (8.50mm versus 7.00mm) requires PCB clearance verification.

All substitute parts maintain ROHS3 compliance and REACH unaffected status consistent with the main part. Product status is Active for all listed alternatives, ensuring continued availability and supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can B32520C1334K000 be used as a direct replacement for 167334K63A-F?

A: B32520C1334K000 is electrically compatible with identical 0.33 µF capacitance, ±10% tolerance, and matching -55°C to 125°C operating temperature. The 100V DC rating exceeds the 63V requirement, providing additional voltage margin. However, physical dimensions differ: B32520C1334K000 measures 10.00mm x 4.00mm with 8.50mm seated height versus 10.50mm x 3.50mm with 7.00mm seated height for the main part. Lead spacing is identical at 7.50mm. PCB layout and clearance must be verified before substitution.

Q: What is the difference between B32529C0334K000, B32529C0334K189, and B32529C0334K289?

A: These three parts are electrically and physically identical. All three feature 0.33 µF capacitance, ±10% tolerance, 63V DC rating, 7.30mm x 3.00mm dimensions, and 5.00mm lead spacing. The primary difference is packaging format: B32529C0334K000 is supplied in Bulk packaging, while B32529C0334K189 and B32529C0334K289 are supplied in Cut Tape (CT) format. Selection depends on assembly process requirements and equipment compatibility.

Q: Are the substitute parts suitable for automotive applications?

A: All substitute parts carry AEC-Q200 automotive-grade certification. The main part 167334K63A-F does not specify automotive rating. If automotive qualification is required for the application, substitute parts B32520C1334J000, B32520C1334K000, B32529C0334K000, B32529C0334K189, and B32529C0334K289 all meet this requirement.

Q: What is the impact of different lead spacing on PCB compatibility?

A: The main part and upgrade parts (B32520C1334J000, B32520C1334K000) feature 7.50mm lead spacing. The similar parts (B32529C0334K000, B32529C0334K189, B32529C0334K289) feature 5.00mm lead spacing. Lead spacing determines hole-to-hole distance on the PCB. Substitution between different lead spacing values requires PCB redesign or use of adapter solutions. Direct substitution without PCB modification is only possible between parts with matching 7.50mm or 5.00mm spacing.

Q: Can B32529C0334K000 replace 167334K63A-F in a space-constrained application?

A: B32529C0334K000 offers a smaller form factor (7.30mm x 3.00mm versus 10.50mm x 3.50mm) and lower seated height (6.50mm versus 7.00mm), making it suitable for space-constrained designs. However, the reduced lead spacing (5.00mm versus 7.50mm) requires PCB layout modification. Electrical parameters are identical, ensuring functional compatibility.

Q: What compliance certifications apply to all substitute parts?

A: All substitute parts maintain ROHS3 compliance and REACH unaffected status, consistent with the main part. Additionally, all substitute parts carry AEC-Q200 automotive-grade certification, which the main part does not specify. All parts are classified under ECCN EAR99 and HTSUS 8532.25.0010.

Q: Is tolerance specification a critical factor in selecting a substitute?

A: Tolerance specification determines capacitance accuracy. The main part specifies ±10% tolerance. Substitute parts B32520C1334K000, B32529C0334K000, B32529C0334K189, and B32529C0334K289 maintain ±10% tolerance. Part B32520C1334J000 offers improved ±5% tolerance. Selection depends on circuit requirements for capacitance accuracy. Tighter tolerance (±5%) provides greater precision but does not prevent substitution in applications tolerating ±10% variation.

Q: What is the significance of the stacked dielectric construction in substitute parts?

A: Substitute parts specify "Polyester, Polyethylene Terephthalate (PET), Metallized - Stacked" dielectric construction, while the main part specifies "Polyester, Metallized" without explicit stacking notation. Both constructions utilize polyester-based dielectric materials and are functionally equivalent for the specified electrical parameters. The stacked construction in substitute parts represents manufacturing process variation within the polyester metallized film capacitor category.
