Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 168684K63F-F are qualified based on the following electrical and mechanical parameters:

Critical Matching Parameters:

• Capacitance: 0.68 µF (exact match required)
• Voltage Rating - DC: 63V (minimum requirement)
• Voltage Rating - AC: 40V (minimum requirement)
• Dielectric Material: Polyester, Metallized (functional equivalence)
• Operating Temperature Range: -55°C to 125°C (full range coverage)
• Mounting Type: Through Hole (mechanical compatibility)
• Package / Case: Radial (form factor compatibility)
• Lead Spacing: 0.197" (5.00mm) (PCB layout compatibility)
• Termination: PC Pins (connection compatibility)
• RoHS Status: ROHS3 Compliant (regulatory compliance)

Allowable Variation:

• Tolerance: ±10% or tighter (±5% is acceptable as an upgrade)
• Physical dimensions: Minor variations within standard manufacturing tolerances are acceptable provided lead spacing and height remain within specified limits

The substitute parts B32529C0684J000 and B32529C0684J289 meet all critical parameters. Both are manufactured by EPCOS - TDK Electronics and feature improved ±5% tolerance compared to the original ±10% specification.

Parameter Comparison

Engineering Selection Recommendations

B32529C0684J000 (EPCOS - TDK Electronics, Bulk Packaging)

This substitute meets all electrical and mechanical requirements with improved ±5% tolerance. The part is ROHS3 compliant and rated to AEC-Q200 automotive standards. Bulk packaging is suitable for high-volume production environments. Lead spacing and height dimensions are compatible with PCB layouts designed for the original 168684K63F-F.

B32529C0684J289 (EPCOS - TDK Electronics, Tape & Box Packaging)

This substitute is electrically and mechanically identical to B32529C0684J000 with the same ±5% tolerance and AEC-Q200 rating. The primary distinction is packaging format: Tape & Box (TB) configuration is appropriate for automated assembly processes and component handling systems. Both EPCOS variants provide superior tolerance specification compared to the original part.

Selection Criteria:

• Choose B32529C0684J000 for bulk component sourcing and manual assembly workflows
• Choose B32529C0684J289 for automated pick-and-place assembly and tape-reel handling systems
• Both substitutes are suitable for applications requiring the original 63VDC, 0.68 µF specification
• The improved ±5% tolerance of EPCOS parts provides tighter capacitance control than the original ±10% specification

Frequently Asked Questions (FAQ)

Q: Can B32529C0684J000 or B32529C0684J289 be used as direct replacements for 168684K63F-F?

A: Yes. Both EPCOS parts meet the critical electrical parameters (0.68 µF, 63VDC, 40VAC) and mechanical specifications (radial through-hole, 5.00mm lead spacing, 9.50mm max height). The ±5% tolerance is tighter than the original ±10%, providing improved capacitance accuracy.

Q: What is the difference between B32529C0684J000 and B32529C0684J289?

A: The electrical and mechanical specifications are identical. The difference is packaging: B32529C0684J000 is supplied in bulk format, while B32529C0684J289 is supplied in Tape & Box (TB) format. Select based on assembly process requirements.

Q: Are there any physical dimension differences that affect PCB compatibility?

A: The original 168684K63F-F measures 7.20mm length; the EPCOS substitutes measure 7.30mm length. This 0.10mm difference is within standard manufacturing tolerances and does not affect PCB layout compatibility. Lead spacing (5.00mm) and maximum seated height (9.50mm) are identical across all three parts.

Q: Do the substitute parts meet the same compliance standards?

A: Yes. All three parts are ROHS3 compliant and REACH unaffected. The EPCOS substitutes additionally carry AEC-Q200 automotive qualification, which exceeds the original part's compliance profile.

Q: What is the operating temperature range for the substitute parts?

A: Both EPCOS substitutes operate across -55°C to 125°C, matching the original 168684K63F-F specification.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, provided the PCB layout accommodates the 7.30mm length of the EPCOS parts (compared to 7.20mm for the original). Lead spacing and height are identical, ensuring direct mechanical compatibility with existing through-hole footprints.
