Substitute Part Grouping Explanation

Substitution of the ECQ-V1124JM9 is based on the following critical parameters:

• Capacitance value: 0.12 µF (exact match required)
• Tolerance: ±5% (electrical equivalence)
• Voltage Rating - DC: 100V (minimum requirement)
• Dielectric type: Polyester metallized-stacked (functional equivalence)
• Mounting configuration: Through-hole radial with 5.00mm lead spacing (mechanical compatibility)
• Termination: PC pins (board interface compatibility)

The B32529C1124J289 from EPCOS - TDK Electronics meets all substitution criteria. This part maintains identical capacitance, tolerance, DC voltage rating, dielectric composition, mounting type, lead spacing, and termination style. The substitute is classified as active product status with enhanced temperature range and automotive-grade compliance.

Parameter Comparison

Engineering Selection Recommendations

The B32529C1124J289 is a direct functional equivalent for the obsolete ECQ-V1124JM9. Both parts share identical electrical specifications (0.12 µF, ±5%, 100V DC) and mechanical compatibility (radial through-hole, 5.00mm lead spacing). The substitute offers extended operating temperature range (-55°C to 125°C versus -40°C to 105°C) and ROHS3 compliance, providing enhanced regulatory alignment for new designs and production continuity.

Selection of the B32529C1124J289 is appropriate for direct replacement in existing applications without circuit redesign. Both parts maintain equivalent performance within the specified electrical and thermal operating envelope.
