160684K63D-F Film Capacitor Equivalent & Substitute Parts

Part Overview

The 160684K63D-F is a 0.68 µF film capacitor manufactured by Cornell Dubilier Electronics (CDE), rated for 63 VDC operation with a ±10% tolerance. This polyester metallized radial capacitor is designed for general-purpose applications and is currently in active production status with 802 units available in inventory.

Substitute parts become necessary when component availability changes, when design requirements necessitate enhanced performance parameters (such as higher voltage ratings or improved temperature stability), or when supply chain transitions require qualification of alternative manufacturers. The substitute parts listed maintain electrical compatibility while potentially offering improved specifications or alternative sourcing options.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 160684K63D-F is determined by the following electrical and mechanical parameters:

Critical Compatibility Parameters:

• Capacitance value: 0.68 µF (must match exactly)
• Voltage rating: DC voltage must equal or exceed 63 VDC
• Dielectric type: Polyester-based films (metallized construction)
• Mounting configuration: Through-hole radial package
• Lead spacing: 0.394" (10.00 mm) pitch
• Operating temperature range: Must support the application's thermal requirements

Allowable Variations for Substitution:

• Tolerance can be equal or tighter (±10% or ±5% acceptable)
• Voltage rating can exceed the minimum requirement (100 VDC acceptable for 63 VDC applications)
• Operating temperature range can be wider (125°C maximum acceptable for 105°C requirement)
• Physical dimensions can vary slightly within radial package constraints
• Manufacturer change is permissible provided electrical parameters remain compatible

All three substitute parts listed meet these criteria and are qualified for direct substitution in applications originally designed for the 160684K63D-F.

Parameter Comparison

Engineering Selection Recommendations

160684K63D-F (Original Part): Cornell Dubilier Electronics maintains active production with 802 units in stock. ROHS3 compliant. Recommended for applications where the 105°C maximum operating temperature is sufficient and design validation is already complete.

DME1P68K-F (CDE Upgrade): Same manufacturer as the original part, offering enhanced voltage margin (100 VDC) and extended operating temperature to 125°C. ROHS3 compliant with 636 units available. Select this option when higher voltage margin or broader temperature performance is required while maintaining CDE product lineage.

B32521C0684J000 (EPCOS): Maintains 63 VDC rating with tighter ±5% tolerance. Supports automotive applications with AEC-Q200 qualification. Extended temperature range to 125°C. ROHS3 compliant with 1429 units in stock. Smaller physical profile (7.00 mm height) compared to alternatives. Select when tighter tolerance and automotive-grade reliability are required.

B32521C1684J000 (EPCOS): Provides highest voltage margin (100 VDC), tighter tolerance (±5%), and extended temperature range to 125°C. AEC-Q200 qualified for automotive use. ROHS3 compliant with highest inventory (3712 units). Identical physical dimensions to the original part. Select as the primary substitute when maximum performance headroom and supply availability are priorities.

All four parts are ROHS3 compliant, actively produced, and carry REACH Unaffected status.

Frequently Asked Questions (FAQ)

Q: Can the 160684K63D-F be replaced with any of these substitute parts in existing designs? A: Yes. All four parts share the identical capacitance (0.68 µF), voltage rating compatibility (all rated ≥63 VDC), radial through-hole mounting configuration, and 10.00 mm lead spacing required for direct PCB substitution.

Q: What is the difference between the two EPCOS parts (B32521C0684J000 and B32521C1684J000)? A: Both EPCOS parts offer tighter ±5% tolerance and AEC-Q200 automotive qualification compared to the ±10% tolerance of the original part. The primary difference is voltage rating: B32521C0684J000 matches the 63 VDC rating, while B32521C1684J000 provides 100 VDC. Choose based on required voltage margin for your application.

Q: Does the DME1P68K-F have any physical compatibility limitations? A: The DME1P68K-F has a slightly larger physical profile (12.50 × 6.00 mm with 13.40 mm height) compared to the original 160684K63D-F (13.00 × 5.00 mm with 11.00 mm height). The B32521C0684J000 offers the most compact footprint at 7.00 mm height. Verify PCB layout clearances before selection.

Q: Which substitute offers the best supply availability? A: B32521C1684J000 has the highest inventory with 3712 units in stock, followed by B32521C0684J000 with 1429 units. Original part 160684K63D-F has 802 units, and DME1P68K-F has 636 units.

Q: Are all parts RoHS and REACH compliant? A: Yes. All four parts maintain ROHS3 compliance and REACH Unaffected status, suitable for markets with environmental compliance requirements.

Q: What is the capacitance tolerance difference between parts, and does it matter? A: The original 160684K63D-F and DME1P68K-F specify ±10% tolerance, while both EPCOS parts (B32521C0684J000 and B32521C1684J000) offer tighter ±5% tolerance. Tighter tolerance is generally beneficial for precision filtering applications. Applications tolerant of ±10% variation are compatible with all options.
