ECH-S1334JZ Equivalent & Substitute Parts

Part Overview

The ECH-S1334JZ is a 0.33 µF film capacitor rated for 100V DC operation, manufactured by Panasonic Electronic Components. This radial through-hole component features a polyphenylene sulfide (PPS) dielectric and is designed for high-frequency and switching applications. The part is currently obsolete, making equivalent substitutes necessary for ongoing production and maintenance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the ECH-S1334JZ is determined by the following critical parameters:

• Capacitance Value: Must be 0.33 µF
• Tolerance: Must be ±5%
• Voltage Rating (DC): Must be rated for 100V or higher
• Mounting Type: Must be through-hole radial configuration
• Lead Spacing: Must match 0.591" (15.00mm) spacing for PCB compatibility
• Termination: Must use PC pins

The substitute parts identified maintain these core electrical and mechanical specifications, ensuring functional equivalence in the target application. Dielectric material variations (polyester/PET metallized vs. PPS) are acceptable provided all electrical ratings and physical dimensions remain compatible.

Engineering Selection Recommendations

160334J100F-F (Cornell Dubilier Electronics): This substitute maintains all critical electrical specifications and lead spacing. The part is active and ROHS3 compliant. Physical dimensions are slightly reduced (0.709" L x 0.197" W vs. 0.807" L x 0.394" W), which may require PCB layout verification. Operating temperature range is -55°C to 105°C, which covers the lower end of the original specification but does not extend to 125°C.

B32522C1334J000 (EPCOS - TDK Electronics): This substitute meets all critical electrical and mechanical requirements with identical lead spacing. The part is active, ROHS3 compliant, and carries AEC-Q200 automotive qualification. Operating temperature range extends to 125°C, matching the original specification. Physical dimensions are comparable to the CDE alternative. This part is suitable for applications requiring automotive-grade reliability.

Both substitutes are electrically and mechanically compatible with the ECH-S1334JZ. Selection should be based on application requirements, temperature range constraints, and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can the 160334J100F-F be used in applications requiring operation at 125°C? A: No. The 160334J100F-F is rated for -55°C to 105°C maximum. Applications requiring 125°C operation must use the B32522C1334J000 or equivalent parts with extended temperature ratings.

Q: Are the physical dimensions of substitute parts compatible with the original PCB layout? A: The 160334J100F-F and B32522C1334J000 both maintain the 0.591" (15.00mm) lead spacing required for PCB compatibility. However, the 160334J100F-F has reduced body dimensions (0.709" L x 0.197" W). PCB layout verification is necessary to confirm clearance and mounting compatibility.

Q: What is the significance of the dielectric material change from PPS to polyester/PET? A: Both dielectric materials meet the specified electrical ratings and voltage requirements. The change does not affect functional equivalence for the stated application parameters. Material selection should be verified against specific application requirements such as frequency response or environmental exposure.

Q: Are both substitute parts RoHS compliant? A: Yes. Both the 160334J100F-F and B32522C1334J000 are ROHS3 compliant, whereas the original ECH-S1334JZ is non-compliant. This compliance status may be required for new designs or regulatory requirements.

Q: Which substitute is recommended for automotive applications? A: The B32522C1334J000 carries AEC-Q200 automotive qualification and is the appropriate choice for automotive applications. The 160334J100F-F does not carry automotive certification.
