ECH-S1152JZ Equivalent & Substitute Parts

Part Overview

The ECH-S1152JZ is a 1500 pF film capacitor manufactured by Panasonic Electronic Components, rated for 100V DC operation with ±5% tolerance. This component features a polyphenylene sulfide (PPS) dielectric material in a radial through-hole package, designed for high-frequency and switching applications. The product is currently obsolete, making equivalent substitute parts necessary for ongoing system maintenance, repairs, and legacy design support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ECH-S1152JZ is determined by the following critical parameters:

• Capacitance Value: 1500 pF (exact match required)
• Tolerance: ±5% (electrical performance equivalence)
• Voltage Rating - DC: 100V (minimum requirement for circuit safety)
• Mounting Type: Through Hole (mechanical compatibility)
• Package / Case: Radial (PCB layout compatibility)
• Lead Spacing: 0.197" (5.00mm) (footprint compatibility)
• Termination: PC Pins (soldering compatibility)

The B32529C1152J000 from EPCOS - TDK Electronics meets all these critical parameters, making it a direct functional equivalent despite differences in dielectric material composition and physical dimensions.

Parameter Comparison

Engineering Selection Recommendations

The B32529C1152J000 is the qualified substitute for the obsolete ECH-S1152JZ based on the following engineering criteria:

• Electrical Equivalence: Identical capacitance (1500 pF), tolerance (±5%), and DC voltage rating (100V) ensure functional compatibility in the circuit.
• Mechanical Compatibility: Matching lead spacing (5.00mm) and radial through-hole package enable direct PCB footprint compatibility.
• Product Availability: The B32529C1152J000 maintains active production status with 1250 units in stock, ensuring supply chain continuity.
• Compliance Status: The substitute part carries ROHS3 compliance and AEC-Q200 automotive qualification, meeting modern regulatory and quality standards.
• Temperature Performance: The extended operating temperature range (-55°C ~ 125°C) of the substitute provides additional thermal margin compared to the original part (-40°C ~ 125°C).

Physical dimensions differ between the two parts; the substitute is more compact. PCB layout verification is required to confirm that the smaller footprint does not create mechanical interference or spacing violations in the target application.

Frequently Asked Questions (FAQ)

Q: Can the B32529C1152J000 be used as a direct replacement for the ECH-S1152JZ?

A: Yes, the B32529C1152J000 is electrically and mechanically compatible. Both parts share identical capacitance (1500 pF), tolerance (±5%), DC voltage rating (100V), lead spacing (5.00mm), and radial through-hole package configuration. The substitute part is physically more compact but maintains the same footprint spacing for PCB mounting.

Q: What is the difference in dielectric material between these parts?

A: The ECH-S1152JZ uses polyphenylene sulfide (PPS) dielectric, while the B32529C1152J000 uses polyester (PET) with metallized-stacked construction. Both materials meet the electrical specifications for this application. Dielectric material selection does not affect substitution eligibility when capacitance, voltage rating, and tolerance are identical.

Q: Are there any temperature range considerations?

A: The B32529C1152J000 operates across -55°C to 125°C, compared to the ECH-S1152JZ range of -40°C to 125°C. The substitute provides extended low-temperature performance, making it suitable for applications requiring operation below -40°C.

Q: Does the physical size difference affect PCB compatibility?

A: The B32529C1152J000 is more compact (7.30mm x 2.50mm vs. 10.00mm x 4.50mm). Lead spacing remains identical at 5.00mm, ensuring footprint compatibility. Verify that the smaller body dimensions do not create clearance issues with adjacent components or mechanical constraints in your specific PCB layout.

Q: What compliance certifications does the substitute part carry?

A: The B32529C1152J000 is ROHS3 compliant and carries AEC-Q200 automotive qualification. The original ECH-S1152JZ does not list these certifications. If your application requires specific compliance standards, confirm that the substitute meets all regulatory requirements for your end-use market.
