Substitute Part Grouping Explanation

Substitute parts for the 160685K63O-F are classified into two categories based on electrical and mechanical compatibility:

Upgrade Substitute (B32523Q1685K000): This EPCOS - TDK Electronics part maintains the 6.8 µF capacitance and ±10% tolerance while providing an elevated DC voltage rating of 100V (versus 63V). The AC voltage rating increases to 63V. This part is suitable for applications requiring higher voltage headroom while preserving the same capacitive value. The operating temperature range extends to 125°C, providing enhanced thermal performance. Physical dimensions are slightly reduced (1.043" L x 0.335" W versus 1.043" L x 0.394" W), and lead spacing remains compatible at 0.886".

Similar Substitute (B32522C0685K000): This EPCOS - TDK Electronics part matches the 160685K63O-F in capacitance (6.8 µF), tolerance (±10%), and voltage ratings (63V DC / 40V AC). The dielectric material is polyester metallized with stacked configuration. This part features a more compact footprint (0.709" L x 0.335" W) and reduced lead spacing (0.591" versus 0.886"), making it suitable for space-constrained applications while maintaining electrical equivalence.

Substitution Criteria:

• Capacitance: 6.8 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage Rating - DC: 63V minimum (equal or higher acceptable)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial (exact match required)
• Termination: PC Pins (exact match required)
• RoHS Status: ROHS3 Compliant (required)

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Identical Electrical and Mechanical Specifications): The B32522C0685K000 provides electrical equivalence to the 160685K63O-F with matching 6.8 µF capacitance, ±10% tolerance, and 63V DC / 40V AC voltage ratings. Both parts are ROHS3 compliant and REACH unaffected. This part is suitable for applications where the original lead spacing of 0.886" is not a constraint. The stacked radial configuration reduces overall footprint while maintaining through-hole mounting compatibility.

For Voltage Margin Enhancement: The B32523Q1685K000 provides the same 6.8 µF capacitance and ±10% tolerance with elevated voltage ratings (100V DC / 63V AC). This part is appropriate for applications requiring higher voltage safety margins or operating in elevated voltage environments. The extended operating temperature range to 125°C provides additional thermal headroom. Lead spacing remains at 0.886", maintaining PCB layout compatibility with the original part. Physical dimensions are slightly reduced.

Compliance and Regulatory Considerations: All three parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Selection among these parts does not introduce regulatory or compliance complications. Inventory availability is confirmed for all substitute options.

Frequently Asked Questions (FAQ)

Q: Can B32523Q1685K000 be used as a direct replacement for 160685K63O-F? A: B32523Q1685K000 is electrically compatible as an upgrade substitute. It maintains the 6.8 µF capacitance and ±10% tolerance. The 100V DC rating exceeds the 63V requirement, providing additional voltage margin. Lead spacing is identical at 0.886", supporting direct PCB mounting. Physical dimensions are slightly smaller. This part is suitable for applications where higher voltage rating and extended temperature range (to 125°C) are beneficial or neutral.

Q: Can B32522C0685K000 be used as a direct replacement for 160685K63O-F? A: B32522C0685K000 is electrically equivalent to 160685K63O-F, matching the 6.8 µF capacitance, ±10% tolerance, and 63V DC / 40V AC voltage ratings. However, the lead spacing differs (0.591" versus 0.886"). This part is suitable for applications where the reduced lead spacing accommodates PCB layout requirements. The stacked radial configuration provides a more compact footprint.

Q: What are the key parameters that determine substitution compatibility? A: Substitution compatibility is determined by capacitance (6.8 µF exact match), tolerance (±10% exact match), DC voltage rating (63V minimum), mounting type (through hole), package type (radial), and termination style (PC pins). Voltage ratings equal to or exceeding the original specification are acceptable. Physical dimensions and lead spacing must be evaluated against PCB layout constraints.

Q: Are there temperature range differences between these parts? A: The 160685K63O-F operates from -55°C to 105°C. Both EPCOS - TDK substitute parts extend the upper temperature limit to 125°C, providing enhanced thermal performance. This difference is not a limitation for substitution; applications operating within the original -55°C to 105°C range remain fully compatible.

Q: Do all parts meet the same regulatory and compliance standards? A: All three parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. No regulatory or compliance differences exist among these parts.

Q: What is the difference between the two EPCOS - TDK substitute parts? A: B32523Q1685K000 provides higher voltage rating (100V DC versus 63V DC) with standard radial configuration and 0.886" lead spacing. B32522C0685K000 maintains the original 63V DC rating with a stacked radial configuration, reduced footprint, and 0.591" lead spacing. Selection depends on voltage margin requirements and PCB layout constraints.
