ECQ-V1683JM Equivalent & Substitute Parts

Part Overview

The ECQ-V1683JM is a 0.068 µF film capacitor manufactured by Panasonic Electronic Components, rated for 100V DC operation with ±5% tolerance. This radial through-hole component uses polyester metallized-stacked dielectric technology and operates across the temperature range of -40°C to 105°C. The part is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

The B32529C1683J000 from EPCOS - TDK Electronics qualifies as a direct substitute based on the following critical parameters:

• Capacitance value matches exactly at 0.068 µF
• Tolerance specification is identical at ±5%
• DC voltage rating meets or exceeds the requirement at 100V
• Dielectric material is compatible (polyester-based, metallized-stacked construction)
• Lead spacing is identical at 0.197" (5.00mm), ensuring PCB footprint compatibility
• Mounting type and termination style (through-hole, PC pins, radial package) are identical
• Operating temperature range of -55°C ~ 125°C encompasses the original specification

Parameter Comparison

Engineering Selection Recommendations

The B32529C1683J000 is suitable as a direct replacement for the ECQ-V1683JM based on electrical parameter equivalence. The substitute part carries active product status, ensuring long-term availability and supply chain stability compared to the obsolete original. The ROHS3 compliance of the substitute aligns with current environmental and regulatory standards. The expanded operating temperature range (-55°C ~ 125°C) provides additional thermal margin beyond the original specification (-40°C ~ 105°C). Physical dimensions are slightly reduced, which may provide layout advantages in space-constrained applications while maintaining identical lead spacing for PCB compatibility.

Frequently Asked Questions (FAQ)

Q: Can the B32529C1683J000 be used as a direct drop-in replacement for the ECQ-V1683JM?

A: Yes. Both parts share identical capacitance (0.068 µF), tolerance (±5%), DC voltage rating (100V), lead spacing (5.00mm), and radial through-hole package configuration. The substitute meets all electrical requirements for direct substitution.

Q: What are the physical differences between these parts?

A: The B32529C1683J000 has a smaller footprint (7.30mm x 2.50mm vs. 7.50mm x 4.00mm) and lower seated height (6.50mm vs. 8.00mm). Lead spacing remains identical at 5.00mm, ensuring PCB compatibility without layout modification.

Q: Does the substitute part meet current compliance standards?

A: Yes. The B32529C1683J000 is ROHS3 compliant and REACH unaffected, meeting current environmental regulations. The original ECQ-V1683JM is REACH unaffected but does not specify RoHS compliance status.

Q: Are there temperature range considerations for substitution?

A: The substitute operates across -55°C ~ 125°C, which exceeds the original specification of -40°C ~ 105°C. This provides additional thermal operating margin and is suitable for applications requiring the original temperature range.

Q: What is the significance of the AC voltage rating difference?

A: The substitute specifies 63V AC rating while the original does not list an AC rating. For DC-only applications, this difference is not relevant. For AC or mixed-signal applications, the 63V AC rating of the substitute should be evaluated against circuit requirements.
