Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 185104J250RGA-F are qualified based on the following criteria:

Electrical Equivalence: All substitute parts maintain identical capacitance (0.1 µF), tolerance (±5%), voltage ratings (250V DC / 160V AC), and dielectric material classification (polyester metallized).

Mechanical Compatibility: Substitutes must feature radial through-hole mounting with PC pin termination. Lead spacing and physical dimensions may vary within the constraints of standard radial package geometries.

Thermal Performance: Operating temperature range of -55°C to 125°C is maintained across all qualified substitutes.

Compliance: All substitute parts are ROHS3 compliant and REACH unaffected, matching the regulatory status of the main part.

Packaging Variations: Substitutes are available in Tape & Reel (TR), Bulk, Cut Tape (CT), and Tape & Box (TB) formats to accommodate different procurement and assembly workflows.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Highest Compatibility):

B32529C3104J000, B32529C3104J189, and B32529C3104J289 are direct electrical and mechanical equivalents to the 185104J250RGA-F. These EPCOS - TDK Electronics parts maintain the 0.197" (5.00mm) lead spacing, identical voltage and capacitance ratings, and full -55°C to 125°C operating range. All three are ROHS3 compliant with AEC-Q200 automotive qualification. Selection between these three depends on packaging requirement: Bulk (J000), Cut Tape (J189), or Cut Tape (J289).

Secondary Substitutes (Lead Spacing Variation):

B32520C3104J000, B32521C3104J000, B32521C3104J289, and B32522C3104J000 maintain full electrical equivalence but feature different lead spacings (7.50mm, 10.00mm, 10.00mm, and 15.00mm respectively). These are suitable for applications where PCB layout accommodates the increased lead spacing. All maintain ROHS3 compliance and AEC-Q200 rating.

CDE Alternative:

160104J250D-F is a Cornell Dubilier Electronics substitute with identical electrical specifications but operates to 105°C maximum (versus 125°C for the main part). This part features 0.394" (10.00mm) lead spacing and is available in Bulk packaging. Selection is appropriate only when the reduced upper temperature limit does not conflict with application requirements.

Frequently Asked Questions (FAQ)

Q: Can B32529C3104J000 directly replace 185104J250RGA-F in my circuit?

A: Yes. Both parts are 0.1 µF, ±5%, 250V DC / 160V AC radial film capacitors with identical lead spacing (5.00mm) and operating temperature range (-55°C to 125°C). Electrical and mechanical compatibility is confirmed.

Q: What is the difference between B32529C3104J189 and B32529C3104J289?

A: Both parts are electrically identical 0.1 µF film capacitors with 5.00mm lead spacing. The difference is in packaging format: J189 is Cut Tape (CT) and J289 is also Cut Tape (CT). Selection depends on your assembly process requirements.

Q: Why does 160104J250D-F have a lower maximum temperature rating?

A: The 160104J250D-F operates to 105°C maximum, compared to 125°C for the 185104J250RGA-F. This is a design characteristic of the CDE 160 series. Use this part only if your application does not require operation above 105°C.

Q: Can I use B32522C3104J000 if my PCB has 15.00mm lead spacing?

A: Yes. B32522C3104J000 maintains all electrical specifications (0.1 µF, ±5%, 250V DC / 160V AC, -55°C to 125°C) and is a qualified substitute. The 15.00mm lead spacing is the only dimensional difference from the main part.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant and REACH unaffected, matching the regulatory status of the 185104J250RGA-F.

Q: What packaging options are available for the B3252 series substitutes?*

A: EPCOS - TDK Electronics B3252* series substitutes are available in Bulk, Cut Tape (CT), and Tape & Box (TB) formats. The 185104J250RGA-F is supplied in Tape & Reel (TR) format. Select packaging based on your procurement and assembly workflow.
