Upgrade Substitutes provide enhanced voltage rating (100V DC, 63V AC) while maintaining the same capacitance, tolerance, and physical dimensions. These parts offer increased safety margin in voltage-stressed applications.

Similar Substitutes maintain identical electrical specifications but differ in physical dimensions and lead spacing. These parts require PCB layout verification before implementation.

Substitution eligibility is determined by the following parameters:

Capacitance value (0.68 µF)
Tolerance (±5%)
Minimum voltage rating (63V DC / 40V AC)

Engineering Selection Recommendations

Direct Substitution (Preferred for Pin-Compatible Replacement)

B32521C0684J000 is the primary direct substitute for the 160684J63D-F. Both parts maintain identical electrical specifications (0.68 µF, ±5%, 63V DC, 40V AC) and lead spacing (10.00 mm). The EPCOS part features an extended operating temperature range (-55°C to 125°C versus -55°C to 105°C) and carries AEC-Q200 automotive qualification. Physical dimensions differ slightly in width (4.00 mm versus 5.00 mm) and height (7.00 mm versus 11.00 mm), requiring verification of available PCB space. Both parts are ROHS3 compliant and carry EAR99 ECCN classification.

Voltage-Upgraded Substitution (Enhanced Safety Margin)

B32521C1684J000 provides a voltage upgrade path with 100V DC rating (versus 63V DC) while maintaining the same 0.68 µF capacitance and ±5% tolerance. This part matches the original physical dimensions (13.00 x 5.00 mm, 10.00 mm lead spacing) and is suitable for applications requiring increased voltage headroom. The extended temperature range (-55°C to 125°C) and AEC-Q200 rating provide additional design margin. This substitution is applicable when circuit voltage stress analysis indicates benefit from higher voltage rating.

Compact Form Factor Substitution (Space-Constrained Applications)

B32529C0684J000 and B32529C0684J289 offer reduced physical dimensions (7.30 x 4.50 mm) with 5.00 mm lead spacing. Both maintain identical electrical specifications to the original part. B32529C0684J289 is supplied in Tape & Box packaging, while B32529C0684J000 is supplied in Bulk packaging. These parts require PCB layout modification due to reduced lead spacing and are suitable for space-constrained designs.

Intermediate Form Factor Substitution (Moderate Space Reduction)

B32520C0684J000 provides a compromise between the original and compact form factors with dimensions of 10.00 x 4.00 mm and 7.50 mm lead spacing. This part maintains electrical equivalence and is suitable for applications with moderate space constraints.

All substitute parts carry ROHS3 compliance and EAR99 ECCN classification, matching the regulatory status of the original part.
