Engineering Selection Recommendations

All identified substitute parts maintain Active product status and ROHS3 compliance, ensuring regulatory alignment with the original 185104J250RGB-F specification.

Direct Electrical Equivalents (Identical Lead Spacing 0.197" / 5.00mm):

B32529C3104J000, B32529C3104J189, and B32529C3104J289 are direct electrical and mechanical equivalents with matching 0.197" lead spacing. These EPCOS - TDK Electronics parts operate across the full -55°C to 125°C temperature range and are suitable for applications requiring identical PCB footprint compatibility. The B3252* series carries AEC-Q200 automotive qualification.

Lead Spacing Variants (Acceptable with Board Layout Verification):

160104J250D-F (CDE, 0.394" spacing), B32520C3104J000 (0.295" spacing), B32521C3104J000 and B32521C3104J289 (0.394" spacing), and B32522C3104J000 (0.591" spacing) provide electrical equivalence with alternative lead spacing. These parts are suitable for applications where PCB layout accommodates the different pitch. The 160104J250D-F operates at -55°C to 105°C, which is narrower than the main part's -55°C to 125°C range.

Packaging Considerations:

Packaging format (Tape & Reel, Bulk, Cut Tape, Tape & Box) does not affect electrical performance. Selection should be based on procurement volume and assembly process requirements.

Frequently Asked Questions (FAQ)

Q: Can B32529C3104J000 replace 185104J250RGB-F directly on the PCB?

A: Yes. B32529C3104J000 is electrically and mechanically equivalent with identical 0.1 µF capacitance, 250V DC / 160V AC rating, ±5% tolerance, and 0.197" (5.00mm) lead spacing. Both are radial through-hole components with PC pin termination.

Q: What is the difference between the CDE 185 series and EPCOS B3252 series?*

A: Both series meet the same electrical specifications (0.1 µF, 250V DC, ±5% tolerance, polyester metallized dielectric). The primary differences are manufacturer, physical dimensions, and packaging options. EPCOS B3252* parts carry AEC-Q200 automotive qualification; CDE 185 series does not list this certification.

Q: Can I use B32521C3104J000 if my PCB has 0.394" (10.00mm) lead spacing?

A: Yes. B32521C3104J000 is electrically equivalent and has 0.394" lead spacing, matching the PCB requirement. Verify that the physical dimensions (0.512" L x 0.157" W, 0.276" height) fit within your mechanical envelope.

Q: Does operating temperature range affect substitution?

A: The main part 185104J250RGB-F operates -55°C to 125°C. Substitute parts with equal or extended range are acceptable. The 160104J250D-F operates -55°C to 105°C, which is narrower; use this part only if your application does not require operation above 105°C.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All identified substitute parts carry ROHS3 compliance, matching the main part specification.

Q: What is the difference between Cut Tape (CT) and Tape & Reel (TR) packaging?

A: Packaging format does not affect electrical performance. Cut Tape is suitable for lower-volume assembly; Tape & Reel is optimized for high-speed automated pick-and-place equipment. Select based on your assembly process.

Q: Can I substitute a part with different lead spacing if I modify the PCB?

A: Lead spacing variants (160104J250D-F, B32520C3104J000, B32521C3104J000, B32521C3104J289, B32522C3104J000) are electrically equivalent but require PCB layout modification. Verify mechanical clearance and trace routing before implementation.

Q: Is B32529C3104J189 different from B32529C3104J289?

A: Both parts are electrically identical with 0.1 µF, 250V DC, ±5% tolerance, and 0.197" lead spacing. The difference is packaging: B32529C3104J189 is Cut Tape; B32529C3104J289 is also Cut Tape. Both are suitable for direct substitution.
