ECQ-V1104JM2 Equivalent & Substitute Parts

Part Overview

The ECQ-V1104JM2 is a 0.1 µF film capacitor rated for 100V DC, manufactured by Panasonic Electronic Components in the ECQ-V series. This component features polyester metallized-stacked construction with radial through-hole mounting and ±5% tolerance. The part is currently obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. Substitute parts must maintain the same capacitance value, tolerance, voltage rating, and mechanical compatibility while meeting modern compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ECQ-V1104JM2 is determined by the following critical parameters:

• Capacitance Value: Must be 0.1 µF (exact match required)
• Tolerance: Must be ±5% or tighter
• Voltage Rating - DC: Must be ≥100V
• Dielectric Type: Polyester or polyester-based (PET) metallized construction
• Mounting Configuration: Through-hole radial with 0.197" (5.00mm) lead spacing
• Termination Style: PC pins

Both substitute parts meet these criteria. The B32529C1104J289 provides direct voltage equivalence at 100V DC, while the B32529C3104J289 offers higher voltage rating at 250V DC. Both maintain identical capacitance, tolerance, lead spacing, and radial through-hole mounting. The EPCOS - TDK Electronics B3252* series uses polyethylene terephthalate (PET) dielectric, which is functionally equivalent to polyester metallized construction for this application category.

Parameter Comparison

Engineering Selection Recommendations

B32529C1104J289 is the primary direct substitute for ECQ-V1104JM2. This part maintains identical DC voltage rating (100V), capacitance (0.1 µF), tolerance (±5%), and lead spacing (5.00mm). The B32529C1104J289 is active in production with ROHS3 compliance and AEC-Q200 automotive qualification, ensuring long-term availability and regulatory compliance. The extended operating temperature range (-55°C ~ 125°C) provides superior thermal performance compared to the original part.

B32529C3104J289 serves as an alternative for applications requiring higher voltage margin. With a 250V DC rating, this part provides 2.5× voltage headroom above the original specification while maintaining all other critical parameters. This substitute is appropriate for designs where voltage stress reduction is beneficial or where board space consolidation allows use of a higher-rated component. Both EPCOS - TDK Electronics substitutes are active products with established supply chains.

Frequently Asked Questions (FAQ)

Q: Can B32529C3104J289 be used in place of ECQ-V1104JM2?

A: Yes. The B32529C3104J289 meets all substitution criteria: identical 0.1 µF capacitance, ±5% tolerance, 5.00mm lead spacing, and radial through-hole mounting. The 250V DC rating exceeds the 100V requirement, providing additional voltage margin. Physical dimensions differ slightly (height 9.50mm vs. 8.00mm original), requiring PCB layout verification.

Q: What is the difference between B32529C1104J289 and B32529C3104J289?

A: Both parts share identical capacitance (0.1 µF), tolerance (±5%), lead spacing (5.00mm), and mounting style. The primary difference is voltage rating: B32529C1104J289 is rated 100V DC (direct match to original), while B32529C3104J289 is rated 250V DC. The higher-voltage part has larger physical dimensions (0.374" height vs. 0.256" height).

Q: Are the EPCOS - TDK Electronics substitutes compatible with the original PCB layout?

A: Lead spacing (5.00mm) is identical, ensuring through-hole compatibility. However, physical dimensions differ: B32529C1104J289 measures 0.256" seated height versus 0.315" for the original; B32529C3104J289 measures 0.374" seated height. PCB layout review is necessary to confirm clearance around component mounting areas.

Q: Do the substitute parts meet automotive standards?

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

Q: Why is the original ECQ-V1104JM2 obsolete?

A: The ECQ-V series from Panasonic has been discontinued. Active equivalent products from EPCOS - TDK Electronics (B3252* series) provide superior compliance certifications, extended temperature ranges, and established long-term supply availability.
