Engineering Selection Recommendations

Direct Electrical Equivalents (Same Voltage Rating):

The parts B32520C0684J000, B32521C0684J000, B32529C0684J000, and B32529C0684J289 are direct electrical equivalents to the 160684J63F-F. All maintain 0.68 µF capacitance, ±5% tolerance, and 63V DC / 40V AC voltage ratings. These EPCOS parts extend the operating temperature range to -55°C to 125°C, providing enhanced thermal performance. All substitute parts are ROHS3 compliant and active in production status.

Selection Criteria by Application:

Identical Footprint Requirement (15.00mm Lead Spacing): Only B32522C3684J000 maintains the original 15.00mm lead spacing. This part operates at 250V DC / 160V AC, providing voltage margin for applications requiring higher transient protection or operating in elevated voltage environments. Physical dimensions are comparable (18.00mm x 7.00mm vs. 18.00mm x 6.00mm).
Compact Form Factor (Reduced PCB Space): Parts B32529C0684J000 and B32529C0684J289 offer the smallest footprint (7.30mm x 4.50mm) with 5.00mm lead spacing. These are suitable for space-constrained designs while maintaining full electrical equivalence. B32529C0684J289 is supplied in Tape & Box packaging; B32529C0684J000 is supplied in Bulk packaging.
Intermediate Footprints: B32520C0684J000 (10.00mm x 4.00mm, 7.50mm spacing) and B32521C0684J000 (13.00mm x 4.00mm, 10.00mm spacing) provide intermediate options for designs with moderate space constraints.

Compliance and Ratings:

All substitute parts carry AEC-Q200 automotive qualification ratings, indicating suitability for automotive and high-reliability applications. All parts are ROHS3 compliant and REACH unaffected. The extended temperature range (-55°C to 125°C) of EPCOS parts exceeds the original specification (-55°C to 105°C), providing additional thermal margin.

Inventory Considerations:

EPCOS B3252* series parts demonstrate higher inventory availability (1429 to 7077 units) compared to the CDE 160684J63F-F (752 units), supporting supply chain continuity and lead time reduction.

Frequently Asked Questions (FAQ)

Q: Can B32522C3684J000 be used as a direct replacement for 160684J63F-F?

A: B32522C3684J000 is electrically compatible with identical capacitance (0.68 µF), tolerance (±5%), and voltage rating (63V DC / 40V AC). It maintains the same 15.00mm lead spacing and radial through-hole mounting. The primary differences are higher voltage rating (250V DC / 160V AC), extended temperature range (-55°C to 125°C), and slightly larger physical dimensions (18.00mm x 7.00mm vs. 18.00mm x 6.00mm). Mechanical fit on the PCB must be verified before substitution.

Q: What is the difference between B32529C0684J000 and B32529C0684J289?

A: Both parts are electrically and mechanically identical with 0.68 µF capacitance, 63V DC rating, and 5.00mm lead spacing. The difference is packaging: B32529C0684J000 is supplied in Bulk packaging, while B32529C0684J289 is supplied in Tape & Box (TB) packaging. Selection depends on assembly process requirements and inventory management preferences.

Q: Are all substitute parts suitable for automotive applications?

A: All EPCOS substitute parts (B3252* series) carry AEC-Q200 automotive qualification ratings. The original CDE 160684J63F-F is specified for general-purpose applications without automotive certification. EPCOS parts are suitable for automotive and high-reliability applications.

Q: What is the impact of lead spacing differences on PCB compatibility?

A: Lead spacing directly determines PCB footprint compatibility. The original 160684J63F-F uses 15.00mm spacing. Substitute parts with different spacing (5.00mm, 7.50mm, 10.00mm) require PCB redesign or use of adapter solutions. B32522C3684J000 maintains 15.00mm spacing for direct PCB compatibility without layout modification.

Q: Do all substitute parts meet RoHS3 compliance?

A: Yes, all substitute parts listed are ROHS3 compliant. The original 160684J63F-F is also ROHS3 compliant. All parts are REACH unaffected.

Q: What is the advantage of the extended temperature range in EPCOS parts?

A: EPCOS substitute parts operate from -55°C to 125°C, compared to the original -55°C to 105°C range. The extended upper temperature limit (125°C vs. 105°C) provides additional thermal margin in high-temperature environments and reduces thermal stress on the component during operation near maximum ambient conditions.

Q: Can substitute parts with higher voltage ratings be used in lower voltage applications?

A: Yes. B32522C3684J000 operates at 250V DC / 160V AC, exceeding the 63V DC / 40V AC requirement of the original part. Higher voltage-rated capacitors are electrically compatible in lower voltage applications and provide additional transient protection margin. Physical dimensions and lead spacing must still be verified for PCB compatibility.

Q: What inventory advantages do EPCOS parts offer?

A: EPCOS B3252* series parts demonstrate significantly higher inventory levels: B32520C0684J000 (7077 units), B32529C0684J000 (6806 units), B32529C0684J289 (2948 units), and B32522C3684J000 (2228 units), compared to CDE 160684J63F-F (752 units). Higher availability supports shorter lead times and improved supply chain reliability.
