ECH-S1222JZ Equivalent & Substitute Parts

Part Overview

The ECH-S1222JZ is a 2200 pF film capacitor rated for 100V DC operation with ±5% tolerance, manufactured by Panasonic Electronic Components. This radial through-hole component utilizes Polyphenylene Sulfide (PPS) dielectric material and is designed for high-frequency and switching applications with an operating temperature range of -40°C to 125°C.

The ECH-S1222JZ is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or repair requirements for systems utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ECH-S1222JZ is determined by the following critical parameters:

• Capacitance value: 2200 pF (exact match required)
• Tolerance: ±5% (exact match required)
• Voltage Rating - DC: 100V (minimum requirement; higher ratings acceptable)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial (exact match required)
• Lead Spacing: 0.197" (5.00mm) (exact match required for PCB compatibility)
• Termination: PC Pins (exact match required)

The B32529C1222J000 manufactured by EPCOS - TDK Electronics meets all critical substitution criteria. While the dielectric material differs (Polyester/PET Metallized - Stacked versus PPS), both materials satisfy the electrical specifications and operating conditions of the original design. Physical dimensions are compatible with the original footprint requirements.

Engineering Selection Recommendations

The B32529C1222J000 is the qualified substitute for the obsolete ECH-S1222JZ. Selection is supported by the following factors:

• Electrical specifications are identical: 2200 pF capacitance, ±5% tolerance, 100V DC rating
• Physical compatibility is maintained: identical lead spacing (5.00mm) and radial through-hole configuration ensure PCB footprint compatibility
• The substitute part is active in production, ensuring supply chain availability
• The B32529C1222J000 carries AEC-Q200 automotive qualification and ROHS3 compliance, providing additional quality assurance
• Operating temperature range of the substitute (-55°C ~ 125°C) exceeds the original specification (-40°C ~ 125°C), providing enhanced thermal margin

Frequently Asked Questions (FAQ)

Q: Can the B32529C1222J000 be used as a direct replacement for the ECH-S1222JZ?

A: Yes. Both components share identical capacitance (2200 pF), tolerance (±5%), DC voltage rating (100V), lead spacing (5.00mm), and radial through-hole configuration. PCB footprint compatibility is confirmed.

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

A: The ECH-S1222JZ uses Polyphenylene Sulfide (PPS) dielectric, while the B32529C1222J000 uses Polyester/PET Metallized - Stacked dielectric. Both materials meet the electrical requirements of the original design specification.

Q: Are there physical size differences?

A: Yes. The B32529C1222J000 is physically smaller (7.30mm x 2.50mm versus 10.00mm x 4.50mm) and has a lower seated height (6.50mm versus 8.50mm). Lead spacing remains identical at 5.00mm, ensuring PCB compatibility. The smaller footprint may provide layout advantages.

Q: Does the substitute part meet compliance requirements?

A: The B32529C1222J000 is ROHS3 compliant and carries AEC-Q200 automotive qualification. Both parts are classified as EAR99 for export control purposes.

Q: What is the temperature operating range difference?

A: The substitute part operates from -55°C to 125°C, compared to the original -40°C to 125°C range. This provides additional low-temperature margin.
