ECQ-V1393JM Equivalent & Substitute Parts

Part Overview

The ECQ-V1393JM is a 0.039 µF film capacitor rated for 100V DC, manufactured by Panasonic Electronic Components as part of the ECQ-V series. This component features polyester metallized-stacked dielectric construction in a radial through-hole package. The part is currently obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. Substitute parts must maintain identical capacitance, tolerance, voltage rating, and lead spacing to ensure direct compatibility in existing circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following critical parameters:

• Capacitance Value: Must be 0.039 µF (no tolerance variation)
• Tolerance: Must be ±5%
• Voltage Rating - DC: Must be 100V minimum
• Lead Spacing: Must be 0.197" (5.00mm) for PCB compatibility
• Mounting Type: Must be Through Hole
• Package Type: Must be Radial
• Termination: Must be PC Pins

All three substitute parts meet these criteria. Physical dimensions (length, width, height) may vary within manufacturing tolerances without affecting functional compatibility, provided lead spacing remains constant.

Parameter Comparison

Engineering Selection Recommendations

168393J100C-F (Cornell Dubilier Electronics) is the direct functional equivalent with active product status and ROHS3 compliance. This part offers the narrowest physical footprint (0.283" L x 0.098" W) among substitutes, which may be advantageous in space-constrained layouts. Extended operating temperature range (-55°C ~ 125°C) exceeds the original specification.

B32529C1393J189 (EPCOS - TDK Electronics, Cut Tape) and B32529C1393J289 (EPCOS - TDK Electronics, Tape & Box) are functionally identical substitutes from the same manufacturer, differing only in packaging format. Both are ROHS3 compliant with active product status. The B3252* series is rated for automotive and EMI/RFI suppression applications. Select based on procurement packaging requirements: Cut Tape for automated assembly or Tape & Box for manual handling and inventory management.

All three substitutes maintain 100V DC rating, 0.197" lead spacing, and ±5% tolerance, ensuring direct PCB compatibility without design modification.

Frequently Asked Questions (FAQ)

Q: Can 168393J100C-F be used as a direct replacement for ECQ-V1393JM?

A: Yes. Both parts share identical capacitance (0.039 µF), tolerance (±5%), DC voltage rating (100V), lead spacing (5.00mm), and radial through-hole package configuration. Physical dimensions differ slightly, but this does not affect electrical performance or PCB mounting compatibility.

Q: What is the difference between the two EPCOS substitute parts (B32529C1393J189 and B32529C1393J289)?

A: Both parts are electrically and mechanically identical. The difference is packaging format only: B32529C1393J189 is supplied in Cut Tape (CT) for automated pick-and-place assembly, while B32529C1393J289 is supplied in Tape & Box (TB) for manual handling and storage. Select based on assembly process requirements.

Q: Are the substitute parts RoHS compliant?

A: Yes. All three substitute parts (168393J100C-F, B32529C1393J189, and B32529C1393J289) are ROHS3 compliant. The original ECQ-V1393JM does not specify RoHS status.

Q: Do the substitute parts have wider operating temperature ranges?

A: Yes. The original ECQ-V1393JM operates from -40°C to 105°C. All three substitutes operate from -55°C to 125°C, providing extended thermal performance. This wider range is compatible with the original specification and does not require design changes.

Q: Can I mix substitute parts from different manufacturers in the same production run?

A: Yes. All three substitutes meet identical electrical and mechanical specifications for capacitance, tolerance, voltage rating, and lead spacing. Mixing manufacturers is acceptable from a functional standpoint. However, procurement and quality control processes should account for different suppliers and certifications.

Q: What is the significance of the lead spacing parameter?

A: Lead spacing (0.197" or 5.00mm) determines PCB hole pattern compatibility. All substitute parts maintain this spacing, ensuring they fit existing PCB designs without modification. Deviation from this parameter would require PCB redesign.
