ECQ-V1683JM2 Equivalent & Substitute Parts

Part Overview

The ECQ-V1683JM2 is a 0.068 µF film capacitor rated for 100V DC, manufactured by Panasonic Electronic Components in the ECQ-V series. This component features a polyester metallized-stacked dielectric with radial through-hole mounting, designed for general-purpose applications. The part is currently obsolete, making equivalent substitutes necessary for ongoing production and maintenance requirements. The ECQ-V series has been discontinued, requiring engineers to identify compatible alternatives that maintain electrical and mechanical compatibility with existing designs.

Substitute Part Grouping Explanation

Substitution of the ECQ-V1683JM2 is determined by strict equivalence across the following critical parameters:

• Capacitance Value: Must be 0.068 µF (no tolerance deviation)
• DC Voltage Rating: Minimum 100V (equal or higher ratings are acceptable)
• Tolerance: ±5% (matching specification)
• Dielectric Type: Polyester-based metallized film (PET acceptable as subset of polyester family)
• Mounting Configuration: Through-hole radial with 0.197" (5.00mm) lead spacing
• Termination Style: PC pins for PCB insertion

The B32529C1683J289 from EPCOS - TDK Electronics meets all substitution criteria. This part maintains identical capacitance, tolerance, and lead spacing while providing enhanced voltage and temperature ratings. The dielectric material (Polyethylene Terephthalate/PET) is a polyester variant, ensuring electrical compatibility. Physical dimensions are comparable, with the substitute featuring a more compact footprint.

Engineering Selection Recommendations

The B32529C1683J289 is the qualified substitute for the obsolete ECQ-V1683JM2. Selection is based on the following engineering criteria:

Electrical Compatibility: Both parts maintain identical capacitance (0.068 µF), tolerance (±5%), and DC voltage rating (100V). The substitute's extended temperature range (-55°C ~ 125°C versus -40°C ~ 105°C) provides superior thermal performance without compromising the original specification envelope.

Mechanical Compatibility: Lead spacing (0.197" / 5.00mm) is identical, ensuring direct PCB footprint compatibility. The substitute's more compact physical dimensions (7.30mm x 2.50mm versus 7.50mm x 4.00mm) and reduced seated height (6.50mm versus 8.00mm) provide layout advantages without requiring design modification.

Compliance & Availability: The B32529C1683J289 is active in production with ROHS3 compliance and AEC-Q200 automotive qualification. The ECQ-V1683JM2 is obsolete with limited inventory (927 pcs). The substitute offers superior long-term supply chain security and regulatory alignment.

Dielectric Material: Both parts use polyester-based metallized film technology. The substitute's PET (Polyethylene Terephthalate) specification is a recognized polyester variant with equivalent electrical performance in this application class.

Frequently Asked Questions (FAQ)

Q: Can the B32529C1683J289 be used as a direct replacement for the ECQ-V1683JM2?

A: Yes. Both parts share identical capacitance (0.068 µF), tolerance (±5%), DC voltage rating (100V), and lead spacing (5.00mm). The substitute meets or exceeds all electrical and mechanical requirements of the original part.

Q: What are the physical dimension differences?

A: The B32529C1683J289 is more compact: 7.30mm x 2.50mm versus 7.50mm x 4.00mm for the ECQ-V1683JM2. Seated height is 6.50mm versus 8.00mm. These differences do not affect PCB footprint compatibility due to identical lead spacing.

Q: Does the substitute support the same temperature range?

A: The substitute supports an extended range: -55°C ~ 125°C compared to -40°C ~ 105°C for the original. This provides additional thermal margin and is fully backward compatible with the original specification.

Q: Is the dielectric material equivalent?

A: Yes. Both parts use polyester-based metallized film technology. The substitute specifies PET (Polyethylene Terephthalate), which is a polyester variant with equivalent electrical performance for general-purpose and EMI/RFI suppression applications.

Q: What is the compliance status of the substitute?

A: The B32529C1683J289 is ROHS3 compliant and carries AEC-Q200 automotive qualification. The original ECQ-V1683JM2 is obsolete with no active compliance certifications listed.

Q: Are there inventory considerations?

A: The B32529C1683J289 has 1,670 pcs in stock (active production), while the ECQ-V1683JM2 has 927 pcs (obsolete status). The substitute offers superior supply chain continuity.
