ECH-S1474JZ Film Capacitor Equivalent & Substitute Parts

Part Overview

The ECH-S1474JZ is a 0.47 µF film capacitor rated for 100V DC, manufactured by Panasonic Electronic Components as part of the ECHS(Z) series. This component is designed for high-frequency and switching applications with a polyphenylene sulfide (PPS) dielectric material and radial through-hole mounting configuration. The part is currently listed as obsolete, making identification of functionally equivalent substitutes essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ECH-S1474JZ is determined by the following critical parameters:

• Capacitance Value: Must be 0.47 µF (no tolerance variation acceptable for direct substitution)
• Voltage Rating (DC): Minimum 100V DC required
• Tolerance: ±5% or better
• Mounting Configuration: Through-hole radial with 0.591" (15.00mm) lead spacing
• Termination Type: PC pins for PCB compatibility
• Package/Case: Radial configuration

The substitute parts identified below meet these core electrical and mechanical requirements, enabling direct board-level replacement without circuit redesign. Variations in dielectric material (polyester/PET versus PPS), operating temperature range, and physical dimensions are secondary considerations that do not prevent functional substitution when the primary parameters align.

Parameter Comparison

Engineering Selection Recommendations

Both identified substitutes meet the electrical and mechanical requirements for direct replacement of the ECH-S1474JZ:

160474J100F-F (Cornell Dubilier Electronics) is an active product with ROHS3 compliance and MSL rating of 1 (unlimited moisture sensitivity). This part is suitable for general-purpose applications and provides the lowest physical profile (0.433" seated height) among the three options.

B32522C1474J000 (EPCOS/TDK Electronics) is an active product with ROHS3 compliance, AEC-Q200 automotive qualification, and extended upper operating temperature matching the original specification (125°C). This part is designated for automotive, EMI, and RFI suppression applications and represents the most direct functional equivalent for demanding thermal environments.

Selection between substitutes should be based on application-specific requirements: general-purpose designs may prioritize the CDE option for cost and availability, while automotive or high-reliability applications should specify the EPCOS/TDK part for its AEC-Q200 rating and thermal performance alignment.

Frequently Asked Questions (FAQ)

Q: Can the 160474J100F-F be used in place of the ECH-S1474JZ without circuit modification?

A: Yes. Both parts share identical capacitance (0.47 µF), DC voltage rating (100V), tolerance (±5%), lead spacing (15.00mm), and radial through-hole mounting. The dielectric material differs (polyester versus PPS), but this does not prevent functional substitution at the board level.

Q: What is the significance of the operating temperature range difference between substitutes?

A: The ECH-S1474JZ and B32522C1474J000 both support -40°C to 125°C operation, while the 160474J100F-F is rated -55°C to 105°C. For applications operating above 105°C, the EPCOS/TDK part is required. For standard industrial temperature ranges, both substitutes are acceptable.

Q: Are the physical dimensions compatible with the original PCB layout?

A: Lead spacing is identical (0.591" / 15.00mm) for all three parts, ensuring PCB footprint compatibility. The 160474J100F-F and B32522C1474J000 have smaller physical envelopes than the original ECH-S1474JZ, which may provide layout advantages but will not cause interference issues.

Q: Which substitute is recommended for automotive applications?

A: The B32522C1474J000 carries AEC-Q200 qualification and is explicitly designated for automotive use. This part is the appropriate selection for automotive circuit designs or systems requiring automotive-grade component certification.

Q: Do the substitute parts require any special handling or storage considerations?

A: The 160474J100F-F has MSL rating 1 (unlimited), requiring no moisture sensitivity precautions. The B32522C1474J000 is not applicable for MSL classification. Both are suitable for standard component storage and handling practices.
