Key Parameters

Substitute Part Grouping Explanation

Substitution of the 160685K100Q-F is determined by the following critical parameters:

Electrical Compatibility: Capacitance value (6.8 µF) and tolerance (±10%) must match exactly. Voltage ratings must equal or exceed the original specification (minimum 100V DC / 63V AC). Dielectric material must be polyester metallized film to maintain equivalent electrical characteristics and frequency response.

Mechanical Compatibility: Mounting type must be through-hole radial configuration. Lead spacing of 1.083" (27.50mm) is required for PCB footprint compatibility. Physical dimensions may vary within reasonable limits provided the component fits the allocated board space and lead spacing remains compatible.

Environmental & Compliance: Operating temperature range must support the application requirements. RoHS3 compliance is mandatory for regulated applications. REACH unaffected status ensures regulatory compliance across markets.

Substitute Categories:

• Upgrade Substitutes: Parts with superior voltage ratings or extended temperature ranges while maintaining identical capacitance and lead spacing
• Direct Substitutes: Parts with identical electrical and mechanical specifications from alternative manufacturers
• Similar Substitutes: Parts with identical electrical specifications but different physical dimensions, requiring PCB layout verification

Engineering Selection Recommendations

DME2W6P8K-F (CDE) - Upgrade Substitute

The DME2W6P8K-F is an upgrade substitute offering superior voltage ratings (250V DC / 160V AC) compared to the original 160685K100Q-F (100V DC / 63V AC). Both parts are manufactured by Cornell Dubilier Electronics, ensuring consistent design philosophy and quality standards. The DME2W6P8K-F maintains identical capacitance (6.8 µF), tolerance (±10%), and lead spacing (27.50mm) for direct PCB compatibility. Extended operating temperature range (-55°C to 125°C versus -55°C to 105°C) provides enhanced thermal performance. Both parts are ROHS3 compliant and REACH unaffected. Physical dimensions are comparable (31.00mm x 13.50mm versus 32.00mm x 13.00mm), with identical seated height (22.50mm). Selection of the DME2W6P8K-F is appropriate when circuit design permits higher voltage ratings or when enhanced thermal margin is required.

B32524Q1685K000 (EPCOS-TDK) - Direct Substitute

The B32524Q1685K000 is a direct substitute from EPCOS-TDK Electronics, matching the original part in capacitance (6.8 µF), tolerance (±10%), and voltage ratings (100V DC / 63V AC). This part is specified for automotive applications and EMI/RFI suppression. Lead spacing (27.50mm) and seated height (22.50mm) are identical to the original, ensuring PCB compatibility. Operating temperature range extends to 125°C, exceeding the original specification. Physical dimensions (31.50mm x 11.00mm) are slightly smaller than the original (32.00mm x 13.00mm), requiring verification of available board space. ROHS3 compliance and REACH unaffected status match the original part. Selection is appropriate for direct replacement in general-purpose and automotive applications.

B32523Q1685K000 (EPCOS-TDK) - Similar Substitute

The B32523Q1685K000 is a similar substitute from EPCOS-TDK Electronics with identical electrical specifications (6.8 µF, ±10%, 100V DC / 63V AC) but different mechanical dimensions. Lead spacing is reduced to 22.50mm (versus 27.50mm original), requiring PCB layout modification. Physical dimensions (26.50mm x 8.50mm) and seated height (16.50mm) are significantly smaller, providing space-saving benefits in compact designs. Operating temperature range extends to 125°C. ROHS3 compliance and REACH unaffected status are maintained. This part is specified for automotive applications and EMI/RFI suppression. Selection requires PCB redesign to accommodate the different lead spacing and is appropriate only when board space constraints justify layout modification.

Frequently Asked Questions (FAQ)

Q: Can the DME2W6P8K-F replace the 160685K100Q-F in any circuit?

A: The DME2W6P8K-F has superior voltage ratings (250V DC / 160V AC) and extended temperature range (-55°C to 125°C). It maintains identical capacitance, tolerance, and lead spacing. Substitution is electrically and mechanically compatible. Physical dimensions are comparable. Verify that the slightly different case size (31.00mm x 13.50mm versus 32.00mm x 13.00mm) fits available board space.

Q: What is the difference between the B32524Q1685K000 and B32523Q1685K000?

A: Both parts have identical electrical specifications (6.8 µF, ±10%, 100V DC / 63V AC). The primary difference is mechanical: B32524Q1685K000 has lead spacing of 27.50mm and dimensions of 31.50mm x 11.00mm; B32523Q1685K000 has lead spacing of 22.50mm and dimensions of 26.50mm x 8.50mm. The B32523Q1685K000 is more compact but requires PCB layout modification due to different lead spacing.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. The original 160685K100Q-F and all three substitute parts (DME2W6P8K-F, B32524Q1685K000, B32523Q1685K000) are ROHS3 compliant and REACH unaffected, meeting regulatory requirements for controlled markets.

Q: Can I use the B32523Q1685K000 as a direct drop-in replacement?

A: No. While the B32523Q1685K000 has identical electrical specifications, the lead spacing differs (22.50mm versus 27.50mm original). Direct PCB installation is not possible without layout modification. This part is suitable only when board redesign is feasible and space constraints justify the smaller form factor.

Q: Which substitute offers the best thermal performance?

A: The DME2W6P8K-F, B32524Q1685K000, and B32523Q1685K000 all extend the operating temperature range to -55°C to 125°C, compared to the original -55°C to 105°C. All three substitutes provide equivalent thermal performance improvement. Selection should be based on voltage rating requirements and mechanical compatibility.

Q: Are there inventory considerations for these substitutes?

A: Inventory levels are provided for reference: 160685K100Q-F (805 pcs), DME2W6P8K-F (1567 pcs), B32524Q1685K000 (1623 pcs), B32523Q1685K000 (2787 pcs). Availability may vary by distributor and time. Verify current stock status with component suppliers.

Q: What applications are these capacitors suitable for?

A: The 160685K100Q-F is specified for general-purpose applications. The EPCOS-TDK substitutes (B32524Q1685K000, B32523Q1685K000) are specified for automotive applications and EMI/RFI suppression. All parts are suitable for general-purpose film capacitor requirements in through-hole designs.
