Key Parameters

Substitute Part Grouping Explanation

Substitution for the ECQ-V1104JM5 is determined by strict equivalence in the following parameters:

• Capacitance value: 0.1 µF (exact match required)
• Tolerance: ±5% (exact match required)
• Dielectric type: Polyester metallized-stacked construction
• Mounting configuration: Through-hole radial package
• Lead spacing: 0.197" (5.00mm) center-to-center
• Voltage rating: Minimum 100V DC (equal or higher acceptable)

The substitute parts identified below meet these core electrical and mechanical requirements. Voltage ratings above 100V DC represent acceptable substitutions as they provide equivalent or superior performance in the same physical footprint and lead configuration.

Parameter Comparison

Engineering Selection Recommendations

Both B32529C1104J189 and B32529C3104J189 are active production parts from EPCOS - TDK Electronics and represent valid substitutes for the obsolete ECQ-V1104JM5.

B32529C1104J189 provides direct voltage equivalence at 100V DC with identical electrical specifications. This part carries AEC-Q200 automotive qualification and ROHS3 compliance, supporting applications requiring automotive-grade reliability.

B32529C3104J189 offers increased voltage margin at 250V DC while maintaining the same capacitance, tolerance, and lead spacing. The higher voltage rating provides additional design headroom for circuits subject to transient overvoltage conditions. This part also carries AEC-Q200 qualification and ROHS3 compliance.

Both substitute parts feature extended operating temperature ranges (-55°C ~ 125°C) compared to the original part (-40°C ~ 105°C), providing improved thermal performance across wider environmental conditions.

Frequently Asked Questions (FAQ)

Q: Can B32529C1104J189 and B32529C3104J189 be used interchangeably with ECQ-V1104JM5?

A: Both parts meet the core substitution criteria: identical capacitance (0.1 µF), tolerance (±5%), dielectric type (polyester metallized-stacked), mounting configuration (through-hole radial), and lead spacing (5.00mm). Physical board layout compatibility is confirmed. The primary difference is voltage rating, with B32529C3104J189 providing 250V versus 100V for both the original and B32529C1104J189.

Q: What is the difference between B32529C1104J189 and B32529C3104J189?

A: Both parts are electrically identical in capacitance and tolerance. The distinction is voltage rating: B32529C1104J189 is rated 100V DC, matching the original part specification, while B32529C3104J189 is rated 250V DC. The higher voltage rating in B32529C3104J189 results in a slightly larger physical height (9.50mm versus 6.50mm seated height).

Q: Are there physical size differences that affect PCB layout?

A: Lead spacing remains constant at 0.197" (5.00mm) across all three parts, ensuring identical hole-to-hole distances on the PCB. Seated heights differ: ECQ-V1104JM5 is 8.00mm, B32529C1104J189 is 6.50mm, and B32529C3104J189 is 9.50mm. Verify clearance above the component in your specific application.

Q: Do the substitute parts meet compliance requirements?

A: Both EPCOS - TDK Electronics parts are ROHS3 compliant and REACH unaffected. Both carry AEC-Q200 automotive qualification, suitable for automotive and industrial applications requiring documented reliability standards.

Q: Which substitute should be selected for new designs?

A: Selection depends on circuit voltage requirements. For circuits operating at or below 100V DC, either part is acceptable. For circuits with potential transient overvoltage or requiring additional voltage margin, B32529C3104J189 at 250V DC is the appropriate choice. Both parts are in active production with established supply chains.
