Substitute Part Grouping Explanation

Substitution for the ECQ-B1682JF is determined by the following critical parameters:

Capacitance Value: 6800 pF (exact match required)
Tolerance: ±5% (exact match required)
Voltage Rating - DC: 100V (minimum requirement; higher ratings acceptable)
Dielectric Material: Polyester-based (polyester, metallized polyester, or polyethylene terephthalate acceptable)
Mounting Type: Through Hole (exact match required)
Package / Case: Radial (exact match required)
Lead Spacing: 0.197" (5.00mm) (exact match required)
Termination: PC Pins (exact match required)

The two substitute parts identified meet all critical substitution criteria while maintaining electrical and mechanical compatibility with the original ECQ-B1682JF specification.

Engineering Selection Recommendations

Both substitute parts are active products with current manufacturing status, providing supply continuity for the obsolete ECQ-B1682JF.

168682J100A-F (Cornell Dubilier Electronics): This substitute maintains the same capacitance, tolerance, and voltage rating. The metallized polyester dielectric provides enhanced performance characteristics. Operating temperature range extends to -55°C ~ 125°C, exceeding the original specification. Physical dimensions are slightly reduced in width (2.50mm vs 3.00mm) and height (6.50mm vs 7.50mm), which may provide layout advantages in space-constrained applications. RoHS3 compliance and REACH unaffected status confirm environmental regulatory alignment.

B32529C1682J000 (EPCOS - TDK Electronics): This substitute meets all electrical specifications with identical capacitance, tolerance, and voltage rating. The metallized polyester with polyethylene terephthalate (PET) stacked construction offers automotive-grade reliability with AEC-Q200 certification. Operating temperature range extends to -55°C ~ 125°C. Physical dimensions are comparable to the CDE alternative with minimal variation. RoHS3 compliance and REACH unaffected status confirm environmental regulatory alignment. Automotive qualification makes this option suitable for applications requiring higher reliability standards.

Frequently Asked Questions (FAQ)

Q: Can I use the 168682J100A-F or B32529C1682J000 as direct replacements for the ECQ-B1682JF?

A: Yes. Both substitute parts match the critical electrical parameters (6800 pF capacitance, ±5% tolerance, 100V DC rating) and mechanical specifications (radial through-hole, 5.00mm lead spacing, PC pins). Physical dimensions show minor variations in width and height, but these do not affect electrical performance or PCB compatibility for standard through-hole mounting.

Q: What is the difference between the two substitute options?

A: The 168682J100A-F uses metallized polyester dielectric, while the B32529C1682J000 uses metallized polyester with polyethylene terephthalate (PET) stacked construction. The B32529C1682J000 carries AEC-Q200 automotive certification, making it suitable for automotive and high-reliability applications. Both parts have identical electrical ratings and extended operating temperature ranges (-55°C ~ 125°C).

Q: Are there any physical installation considerations when switching to these substitutes?

A: The substitute parts are slightly smaller in width and height compared to the original ECQ-B1682JF. The lead spacing remains identical at 5.00mm, ensuring PCB footprint compatibility. The reduced physical dimensions may provide layout advantages but do not require design modifications.

Q: Do these substitutes meet environmental and regulatory requirements?

A: Both substitute parts are RoHS3 compliant and REACH unaffected, meeting current environmental regulations. The B32529C1682J000 additionally carries AEC-Q200 automotive qualification for applications requiring automotive-grade reliability.

Q: What is the inventory status of these substitute parts?

A: The 168682J100A-F has 795 pcs in stock, and the B32529C1682J000 has 2136 pcs in stock, providing adequate supply for production requirements.
