Substitute Part Grouping Explanation

Substitute parts for the 185683K100RHB-F are identified based on strict electrical and mechanical parameter alignment. The substitution logic is organized into two categories:

Direct Substitutes (Electrical and Mechanical Compatibility): Parts that maintain identical or superior electrical specifications (capacitance, voltage rating, tolerance, dielectric material, temperature range) and compatible mechanical form factors (through-hole radial mounting, lead spacing, physical dimensions).

Functional Equivalents (Electrical Compatibility with Form Factor Variation): Parts that maintain identical electrical specifications but differ in physical dimensions, lead spacing, or packaging format. These require PCB design verification for hole pattern compatibility.

The following parameters determine substitution eligibility:

Capacitance value must equal 0.068 µF
DC voltage rating must equal or exceed 100V
Tolerance must equal or be tighter than ±10%
Dielectric material must be polyester-based, metallized construction
Operating temperature range must encompass -55°C to 125°C
Mounting type must be through-hole radial
RoHS3 compliance must be maintained

Engineering Selection Recommendations

B32529C1683K189 (EPCOS - TDK Electronics): This substitute provides direct electrical and mechanical compatibility with the 185683K100RHB-F. Physical dimensions (0.287" L x 0.098" W, 6.50mm height) and lead spacing (0.197" / 5.00mm) are equivalent, enabling direct PCB footprint substitution. The dielectric material is polyester-based PET with metallized stacked construction, maintaining performance within the specified operating temperature range (-55°C to 125°C). ROHS3 compliance and REACH unaffected status align with regulatory requirements. This part is suitable for direct replacement in existing designs without PCB modification. Significantly higher inventory availability (10119 pcs) supports supply chain continuity.

DMT1S68K-F (Cornell Dubilier Electronics): This substitute maintains identical electrical specifications (0.068 µF, 100VDC, ±10% tolerance, -55°C to 125°C operating range) and is manufactured by the same supplier as the main part. However, physical dimensions (0.559" L x 0.276" W, 14.06mm height) and lead spacing (0.421" / 10.70mm) differ significantly from the main part. This configuration requires PCB design verification to confirm hole pattern compatibility. The larger form factor may present space constraints in compact layouts. ROHS3 compliance is maintained. This substitute is applicable only when PCB hole patterns accommodate the increased lead spacing and physical dimensions.

Both substitutes maintain Active product status and full regulatory compliance. Selection between substitutes depends on PCB layout constraints and lead spacing requirements.

Frequently Asked Questions (FAQ)

Q: Can the B32529C1683K189 be used as a direct replacement for the 185683K100RHB-F without PCB modification?

A: Yes. The B32529C1683K189 maintains identical lead spacing (0.197" / 5.00mm), equivalent physical dimensions (0.287" L x 0.098" W, 6.50mm height), and matching electrical specifications (0.068 µF, 100VDC, ±10% tolerance). Direct PCB footprint substitution is supported without design changes.

Q: Why does the DMT1S68K-F have different lead spacing?

A: The DMT1S68K-F belongs to the DMT series, which uses a 0.421" (10.70mm) lead spacing standard. This differs from the 185 series 0.197" (5.00mm) spacing. The larger spacing accommodates the increased physical dimensions (0.559" L x 0.276" W) of this component design. PCB hole pattern verification is required before substitution.

Q: Are all three parts ROHS3 compliant?

A: Yes. The 185683K100RHB-F, DMT1S68K-F, and B32529C1683K189 are all ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and use.

Q: What is the difference between polyester metallized and polyester PET metallized stacked construction?

A: Both are polyester-based dielectric materials with metallized construction. The B32529C1683K189 uses a stacked configuration, which is a manufacturing variation that does not alter the electrical performance specifications (capacitance, voltage rating, tolerance, temperature range) required for substitution compatibility.

Q: Which substitute has the best supply availability?

A: The B32529C1683K189 has the highest inventory level at 10119 pcs, compared to 1704 pcs for the DMT1S68K-F and 799 pcs for the main part. This availability advantage supports supply chain planning and reduces lead time risk.

Q: Can I use the DMT1S68K-F in a design originally specified for the 185683K100RHB-F?

A: Only if the PCB hole pattern accommodates the 0.421" (10.70mm) lead spacing and the larger physical dimensions (0.559" L x 0.276" W, 14.06mm height) do not create space conflicts. The electrical specifications are fully compatible, but mechanical verification is mandatory before implementation.

Q: What packaging formats are available for these substitutes?

A: The 185683K100RHB-F is supplied in Tape & Reel (TR) format. The B32529C1683K189 is available in Cut Tape (CT) format. The DMT1S68K-F is supplied in Bulk format. Packaging selection depends on assembly process requirements and order quantity.
