ECQ-V1683JM3 Equivalent & Substitute Parts

Part Overview

The ECQ-V1683JM3 is a 0.068 µF film capacitor rated for 100V DC, manufactured by Panasonic Electronic Components. This radial through-hole component uses polyester metallized-stacked dielectric technology and operates across a temperature range of -40°C to 105°C. The part is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. The ECQ-V series has been discontinued, requiring engineers to identify compatible alternatives that maintain electrical and mechanical compatibility with existing designs.

Key Parameters

Substitute Part Grouping Explanation

The B32529C1683J289 from EPCOS - TDK Electronics qualifies as a direct substitute based on the following critical parameters:

• Capacitance Match: Both parts are rated at 0.068 µF
• Voltage Rating: The substitute meets the 100V DC requirement
• Tolerance: Both maintain ±5% tolerance specification
• Dielectric Technology: Both use polyester metallized-stacked construction
• Mounting Configuration: Both are through-hole radial packages
• Lead Spacing: Both maintain 0.197" (5.00mm) lead spacing, ensuring PCB footprint compatibility
• Termination: Both use PC pins for standard through-hole soldering

The substitute part operates at an extended temperature range (-55°C ~ 125°C) compared to the original, providing broader environmental capability. The B32529C1683J289 is currently in active production status, ensuring long-term availability and supply chain stability.

Parameter Comparison

Engineering Selection Recommendations

The B32529C1683J289 is the qualified substitute for the obsolete ECQ-V1683JM3. Selection is based on:

• Electrical Equivalence: Identical capacitance, voltage rating, and tolerance specifications ensure direct functional replacement
• Mechanical Compatibility: Matching lead spacing (5.00mm) and radial through-hole configuration permit direct PCB footprint compatibility without layout modifications
• Active Production Status: The substitute is in active production, providing assured long-term availability and supply chain continuity
• Compliance: The substitute meets ROHS3 compliance requirements, supporting modern manufacturing and environmental standards
• Extended Operating Range: The wider temperature specification (-55°C ~ 125°C) provides enhanced performance margin over the original part's range

The substitute's compact physical dimensions (7.30mm x 2.50mm versus 7.50mm x 4.00mm) represent a minor reduction in footprint, which is advantageous for space-constrained applications and does not impact electrical performance.

Frequently Asked Questions (FAQ)

Q: Can the B32529C1683J289 be used as a direct replacement without PCB modifications?

A: Yes. The lead spacing of 0.197" (5.00mm) is identical to the original part, and both use radial through-hole configuration. The substitute's smaller physical dimensions do not affect PCB compatibility.

Q: What is the significance of the extended operating temperature range in the substitute?

A: The B32529C1683J289 operates from -55°C to 125°C, compared to the original's -40°C to 105°C range. This provides additional thermal margin and permits use in more demanding environmental conditions without performance degradation.

Q: Are there any electrical performance differences between the two parts?

A: No. Both parts maintain identical capacitance (0.068 µF), voltage rating (100V DC), and tolerance (±5%). The dielectric technology is equivalent, ensuring matching electrical behavior in circuit operation.

Q: Why is the original part classified as obsolete?

A: The ECQ-V series has been discontinued by Panasonic Electronic Components. The B32529C1683J289 from the active B3252* series represents the current production equivalent.

Q: Does the substitute meet modern compliance requirements?

A: Yes. The B32529C1683J289 is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic component manufacturing and use.

Q: What is the packaging difference between the two parts?

A: The original ECQ-V1683JM3 packaging is not specified in available data. The substitute B32529C1683J289 is supplied in Tape & Box (TB) packaging, which is standard for through-hole film capacitors in production environments.
