Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 168683K63A-F is determined by the following mandatory parameters: capacitance value (0.068 µF), voltage rating (minimum 63V DC), tolerance class, dielectric composition, mounting configuration (through-hole radial), lead spacing (5.00mm), and environmental compliance certifications. The EPCOS - TDK Electronics B3252* series parts meet these substitution criteria with variations in packaging format and specification upgrades.

Parts are grouped into the following categories:

Direct Equivalents (Identical electrical and mechanical specifications with packaging or inventory variations):

• B32529C0683K000 (Bulk packaging)
• B32529C0683K289 (Cut Tape packaging)

Upgraded Substitutes (Enhanced specifications while maintaining backward compatibility):

• B32529C0683J000 (±5% tolerance upgrade; maintains 63V DC rating)
• B32529C1683K189 (100V DC rating upgrade; maintains ±10% tolerance)

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (168683K63A-F specifications maintained): B32529C0683K000 and B32529C0683K289 provide electrically and mechanically equivalent alternatives. Selection between these parts depends on packaging requirements: B32529C0683K000 is supplied in bulk format, while B32529C0683K289 is available in cut tape format. Both maintain ROHS3 compliance and REACH unaffected status with active product availability.

For Tolerance Enhancement: B32529C0683J000 offers tighter ±5% tolerance compared to the original ±10% specification while maintaining 63V DC voltage rating, operating temperature range, and all mechanical parameters. This part is appropriate for circuits requiring improved capacitance accuracy without increased voltage stress requirements.

For Voltage Margin Increase: B32529C1683K189 upgrades the DC voltage rating to 100V while preserving the 0.068 µF capacitance and ±10% tolerance. This substitute is applicable in circuits where increased voltage safety margin is required or where voltage transients present elevated stress conditions. The part maintains identical thermal and mechanical specifications.

All substitute parts maintain ROHS3 compliance and REACH unaffected status, ensuring equivalent regulatory positioning to the original part number.

Frequently Asked Questions (FAQ)

Q: What are the critical parameters that determine substitution compatibility? A: Substitution eligibility is determined by capacitance value (0.068 µF), voltage rating (minimum 63V DC for direct equivalents), tolerance class compatibility, dielectric composition (polyester metallized), through-hole radial mounting configuration, and 5.00mm lead spacing. All candidates must maintain ROHS3 compliance and REACH unaffected designation.

Q: Can B32529C1683K189 (100V rated) be used in place of 168683K63A-F (63V rated)? A: Yes. B32529C1683K189 is a rated voltage upgrade that maintains all other electrical and mechanical specifications. Higher voltage rating provides increased safety margin and does not degrade performance in circuits operating at 63V DC or below.

Q: What is the difference between B32529C0683K000 and B32529C0683K289? A: These parts are electrically and mechanically identical. The primary difference is packaging: B32529C0683K000 is supplied in bulk format, while B32529C0683K289 is supplied in cut tape format. Selection depends on procurement and assembly process requirements.

Q: Does B32529C0683J000 have mechanical compatibility with the original part? A: Yes. B32529C0683J000 maintains identical mechanical dimensions, lead spacing (5.00mm), radial package configuration, and through-hole mounting type. The upgrade involves tighter capacitance tolerance (±5% versus ±10%) without mechanical or thermal changes.

Q: Are physical dimensions identical across all substitute parts? A: Dimension differences exist between the original part and EPCOS substitutes. The 168683K63A-F measures 0.283" x 0.098" (7.20mm x 2.50mm) in length, while B3252* series parts measure 0.287" x 0.098" (7.30mm x 2.50mm). Height-seated dimension (6.50mm maximum) and lead spacing (5.00mm) remain identical. PCB layout and component placement must accommodate the 0.004" (0.10mm) length difference.

Q: Which part should be selected for automotive applications? A: B32529C0683K000, B32529C0683K289, B32529C0683J000, and B32529C1683K189 carry AEC-Q200 automotive rating, making them suitable for automotive circuit applications. The original 168683K63A-F is specified for general-purpose use without automotive rating designation.
