Substitute Part Grouping Explanation

Substitution relationships are established based on strict electrical and mechanical parameter matching. All substitute parts maintain identical capacitance (0.1 µF), voltage rating (100VDC), dielectric material (polyester metallized), mounting type (through hole radial), and lead spacing (5.00mm). Parts are grouped into three categories:

Direct Equivalents: Parts with identical electrical specifications and packaging compatibility. These include Cornell Dubilier 168104K100H-F and EPCOS B32529C1104K000, B32529C1104K189, and B32529C1104K289. Packaging format differences (Tape & Reel versus Bulk or Cut Tape) do not affect electrical equivalence.

Upgrade Specifications: Parts with improved tolerance (±5% versus ±10%), enabling use in applications requiring tighter capacitance accuracy. These include Cornell Dubilier 168104J100H-F and EPCOS B32529C1104J000, B32529C1104J189, and B32529C1104J289.

Engineering Selection Recommendations

Direct Substitution (Electrical Equivalence): The Cornell Dubilier 168104K100H-F and EPCOS B32529C1104K series (K000, K189, K289) are direct electrical equivalents to the 185104K100RHB-F. All maintain 0.1 µF capacitance, ±10% tolerance, 100VDC rating, and 5.00mm lead spacing. The primary difference is packaging format: the original part is supplied in Tape & Reel, while equivalents are available in Bulk or Cut Tape. All parts are ROHS3 compliant and rated for -55°C to 125°C operation. Selection among these equivalents depends on procurement packaging requirements and inventory availability.

Upgraded Tolerance Selection: When circuit design requires tighter capacitance tolerance, the Cornell Dubilier 168104J100H-F and EPCOS B32529C1104J series (J000, J189, J289) provide ±5% tolerance while maintaining all other electrical specifications. These upgrades are suitable for applications with stricter component accuracy requirements. EPCOS parts carry AEC-Q200 automotive qualification.

Dimensional Constraint Considerations: The Cornell Dubilier 160104K100C-F maintains electrical specifications but features a larger physical footprint (10.00mm lead spacing versus 5.00mm) and reduced upper operating temperature limit (-55°C to 105°C). This part is suitable only when PCB layout accommodates the larger spacing and application temperature does not exceed 105°C.

Larger Case Alternative: The Cornell Dubilier DMT1P1K-F provides the same capacitance and tolerance with significantly larger dimensions (13.80mm lead spacing) and marginally higher AC voltage rating (65V). This part is applicable only when physical space permits and the larger form factor is acceptable.

Frequently Asked Questions (FAQ)

Q: Can I substitute 185104K100RHB-F with 168104K100H-F?

A: Yes. Both parts are electrically identical with 0.1 µF capacitance, ±10% tolerance, and 100VDC rating. The difference is packaging: 185104K100RHB-F is Tape & Reel while 168104K100H-F is Bulk. Electrical performance and PCB compatibility are equivalent.

Q: What is the difference between K-tolerance and J-tolerance parts?

A: K-tolerance parts (±10%) and J-tolerance parts (±5%) differ only in capacitance accuracy. J-tolerance parts are suitable for applications requiring tighter component specifications. All other electrical parameters remain identical.

Q: Are EPCOS B32529C1104K parts compatible with the original Cornell Dubilier part?

A: Yes. EPCOS B32529C1104K000, B32529C1104K189, and B32529C1104K289 are electrically equivalent to 185104K100RHB-F. All maintain 0.1 µF, ±10% tolerance, 100VDC, and 5.00mm lead spacing. Packaging differs (Bulk or Cut Tape versus Tape & Reel). EPCOS parts carry AEC-Q200 automotive qualification.

Q: Can I use 160104K100C-F as a substitute?

A: 160104K100C-F is electrically equivalent but has different physical dimensions (10.00mm lead spacing versus 5.00mm) and lower maximum operating temperature (105°C versus 125°C). Use only if PCB layout accommodates the larger spacing and application temperature does not exceed 105°C.

Q: What does "Cut Tape" packaging mean?

A: Cut Tape (CT) is a partial reel format where components are supplied on tape but cut to specific lengths, typically for smaller order quantities. Tape & Reel (TR) and Bulk formats differ in presentation but contain identical components.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant, meeting regulatory requirements for hazardous substance restrictions.

Q: Which substitute has the highest inventory availability?

A: EPCOS B32529C1104J000 has the highest inventory at 23,389 pieces, followed by Cornell Dubilier 168104J100H-F at 19,920 pieces.
