ECH-S1682JZ Film Capacitor Equivalent & Substitute Parts

Part Overview

The ECH-S1682JZ is a 6800 pF film capacitor rated at 100V DC, manufactured by Panasonic Electronic Components. This component features a Polyphenylene Sulfide (PPS) dielectric material in a radial through-hole configuration. The part is currently obsolete, making equivalent substitutes necessary for ongoing production, maintenance, and repair applications. Substitute parts must maintain the same capacitance value, voltage rating, tolerance, and mounting characteristics to ensure functional compatibility in existing circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ECH-S1682JZ are qualified based on the following electrical and mechanical parameters:

• Capacitance Value: Must be 6800 pF
• Tolerance: Must be ±5%
• Voltage Rating - DC: Must be 100V or higher
• Mounting Type: Must be Through Hole
• Package / Case: Must be Radial
• Termination: Must be PC Pins
• Operating Temperature Range: Must support at least -40°C ~ 125°C

The substitute parts identified below meet these core requirements. Dielectric material variations (Polyester, Metallized Polyethylene Terephthalate) are acceptable as they provide equivalent electrical performance at the specified voltage and capacitance ratings. Physical dimensions may vary within acceptable tolerances for PCB layout compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are active products with current manufacturing support, addressing the obsolescence of the ECH-S1682JZ.

168682J100A-F (Cornell Dubilier Electronics): This part is ROHS3 compliant and carries MSL Level 1 (Unlimited), indicating superior moisture resistance for storage and handling. The extended operating temperature range (-55°C ~ 125°C) provides additional thermal margin. Lead spacing of 0.197" (5.00mm) is tighter than the original part, requiring PCB layout verification.

B32529C1682J000 (EPCOS - TDK Electronics): This part carries AEC-Q200 automotive qualification and ROHS3 compliance. The extended operating temperature range (-55°C ~ 125°C) and MSL Not Applicable rating provide robust environmental performance. Lead spacing of 0.197" (5.00mm) requires PCB layout verification. Higher inventory availability (2136 Pcs) supports production continuity.

Both parts meet the core electrical requirements. Selection should be based on PCB layout compatibility (lead spacing), supply chain availability, and application-specific certifications (automotive vs. general purpose).

Frequently Asked Questions (FAQ)

Q: Can the 168682J100A-F or B32529C1682J000 be used as direct replacements for the ECH-S1682JZ?

A: Both parts meet the core electrical specifications (6800 pF, ±5%, 100V DC, through-hole radial). However, lead spacing differs: the original part has 0.295" (7.50mm) spacing, while both substitutes have 0.197" (5.00mm) spacing. PCB layout verification is required before implementation.

Q: What is the significance of the different dielectric materials?

A: The ECH-S1682JZ uses Polyphenylene Sulfide (PPS), while the substitutes use Polyester or Polyethylene Terephthalate (PET) with metallization. All three materials are suitable for 100V DC film capacitor applications at 6800 pF. The substitutes' metallized construction provides equivalent electrical performance with different physical characteristics.

Q: Are there temperature range differences that affect compatibility?

A: The ECH-S1682JZ operates from -40°C ~ 125°C. Both substitutes extend the lower limit to -55°C, providing additional thermal margin. This does not affect compatibility in applications using the original temperature range.

Q: Which substitute part should be selected for automotive applications?

A: The B32529C1682J000 carries AEC-Q200 automotive qualification, making it the appropriate choice for automotive circuit designs. The 168682J100A-F is rated for general purpose applications.

Q: What is the impact of MSL rating on part selection?

A: The 168682J100A-F carries MSL Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage and handling. The B32529C1682J000 has MSL Not Applicable, indicating the part is not moisture-sensitive. Both are suitable for standard manufacturing environments.

Q: How does lead spacing affect PCB compatibility?

A: The original ECH-S1682JZ has 0.295" (7.50mm) lead spacing. Both substitutes have 0.197" (5.00mm) spacing. Existing PCB designs with 7.50mm hole spacing will require modification or use of adapter techniques to accommodate the 5.00mm spacing of substitute parts.
