Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 168684J63F-F is determined by strict equivalence across the following critical parameters:

Mandatory Equivalence Parameters:

• Capacitance: 0.68 µF (exact match required)
• Tolerance: ±5% (exact match required)
• Voltage Rating (DC): 63V (exact match required)
• Voltage Rating (AC): 40V (exact match required)
• Dielectric Material: Polyester, Metallized (exact match required)
• Operating Temperature Range: -55°C to 125°C (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package Type: Radial (exact match required)
• Termination: PC Pins (exact match required)

Allowable Variation Parameters:

• Physical dimensions (length, width, height) may vary within PCB layout constraints
• Lead spacing may vary within PCB hole pattern constraints
• Packaging format (Bulk vs. Tape & Box) may vary based on procurement requirements
• Manufacturer and series designation may vary

All substitute parts listed below meet the mandatory equivalence parameters. Physical dimension variations are noted in the Parameter Comparison table to support PCB layout verification.

Engineering Selection Recommendations

Direct Substitutes (Identical Footprint):

B32529C0684J000 and B32529C0684J289 are direct substitutes for the 168684J63F-F. Both parts share identical electrical specifications, physical dimensions (7.30mm × 4.50mm length and width), height (9.50mm), and lead spacing (5.00mm). The primary difference is packaging format: B32529C0684J000 is supplied in Bulk format, while B32529C0684J289 is supplied in Tape & Box format. Both are ROHS3 compliant and carry AEC-Q200 automotive qualification. These parts are suitable for direct PCB layout substitution without design modification.

Footprint-Compatible Substitutes (Requires PCB Layout Verification):

B32520C0684J000 and B32521C0684J000 are electrically equivalent but feature different physical dimensions and lead spacing. B32520C0684J000 measures 10.00mm × 4.00mm with 7.50mm lead spacing and 8.50mm seated height. B32521C0684J000 measures 13.00mm × 4.00mm with 10.00mm lead spacing and 7.00mm seated height. These parts are suitable for substitution only when PCB layout accommodates the larger footprint and increased lead spacing. Both are ROHS3 compliant and carry AEC-Q200 automotive qualification.

Compliance Status:

All substitute parts are ROHS3 compliant and REACH unaffected. EPCOS substitute parts carry AEC-Q200 automotive qualification, which exceeds the general-purpose classification of the original CDE part. This qualification is additive and does not restrict use in non-automotive applications.

Frequently Asked Questions (FAQ)

Q: Can B32520C0684J000 or B32521C0684J000 be used as direct replacements without PCB modification?

A: No. These parts have different lead spacing (7.50mm and 10.00mm respectively) compared to the original 5.00mm spacing. PCB hole pattern verification is required before substitution. If the PCB is designed for 5.00mm spacing, these parts cannot be installed without rework.

Q: What is the difference between B32529C0684J000 and B32529C0684J289?

A: Both parts are electrically and physically identical. The difference is packaging format only. B32529C0684J000 is supplied in Bulk packaging, while B32529C0684J289 is supplied in Tape & Box format. Selection depends on procurement and assembly process requirements.

Q: Are the EPCOS substitute parts suitable for automotive applications?

A: Yes. All EPCOS substitute parts carry AEC-Q200 qualification, which certifies suitability for automotive applications. The original CDE part does not specify automotive qualification but can be used in automotive circuits where AEC-Q200 is not mandated.

Q: Do all substitute parts meet the same electrical specifications as the original?

A: Yes. All substitute parts listed are electrically equivalent with identical capacitance (0.68 µF), tolerance (±5%), voltage ratings (63V DC / 40V AC), dielectric material (polyester metallized), and operating temperature range (-55°C to 125°C).

Q: What should I verify before selecting a substitute part?

A: Verify the following: (1) PCB hole pattern and lead spacing compatibility, (2) available PCB space for component height and length, (3) packaging format requirements for your assembly process, (4) whether AEC-Q200 automotive qualification is required for your application.

Q: Are there any performance differences between the CDE original and EPCOS substitutes?

A: No performance differences exist within the specified electrical parameters. All parts meet identical capacitance, voltage, tolerance, and temperature specifications. EPCOS parts include metallized-stacked dielectric construction and AEC-Q200 qualification, which are additive features that do not alter baseline performance.
