ECH-S1H222GZ Equivalent & Substitute Parts

Part Overview

The ECH-S1H222GZ is a 2200 pF film capacitor manufactured by Panasonic Electronic Components, rated for 50V DC operation with ±2% tolerance. This radial through-hole component utilizes polyphenylene sulfide (PPS) dielectric material and is designed for high-frequency and switching applications. The part is currently obsolete, making substitute components necessary for new designs or production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ECH-S1H222GZ is determined by the following critical parameters:

• Capacitance Value: 2200 pF (exact match required)
• Tolerance: ±2% (exact match required)
• Voltage Rating - DC: 50V (minimum requirement)
• Dielectric Material: Polyphenylene Sulfide (PPS) (exact match required)
• Mounting Type: Through Hole or Surface Mount (design-dependent)

The ECH-U1H222GX5 qualifies as a substitute based on matching capacitance, tolerance, voltage rating, and dielectric material. However, this substitute transitions from through-hole radial to surface-mount 0805 (2012 Metric) packaging, requiring circuit board redesign.

Parameter Comparison

Engineering Selection Recommendations

The ECH-U1H222GX5 is the qualified substitute for the ECH-S1H222GZ based on electrical parameter equivalence. The substitute part is currently in active production status with 36,190 units available in inventory, compared to the obsolete main part with 1,155 units remaining.

Selection between these parts depends on circuit board design constraints:

• Through-hole radial requirement: ECH-S1H222GZ (limited availability due to obsolete status)
• Surface-mount design: ECH-U1H222GX5 (active production, extended temperature range to -55°C, RoHS3 compliant, REACH unaffected)

The ECH-U1H222GX5 offers superior compliance certifications and broader operating temperature capability, making it the preferred choice for new designs where board layout permits surface-mount implementation.

Frequently Asked Questions (FAQ)

Q: Can the ECH-U1H222GX5 directly replace the ECH-S1H222GZ on existing circuit boards?

A: No. The ECH-S1H222GZ is a through-hole radial component with 5.00mm lead spacing, while the ECH-U1H222GX5 is a surface-mount 0805 (2012 Metric) component. Circuit board redesign is required for footprint compatibility.

Q: Are the electrical characteristics identical between these parts?

A: The capacitance (2200 pF), tolerance (±2%), DC voltage rating (50V), and dielectric material (PPS) are identical. The ECH-U1H222GX5 extends the operating temperature range to -55°C (compared to -40°C minimum for the main part) and uses a metallized-stacked PPS construction.

Q: What is the inventory status for each part?

A: The ECH-S1H222GZ (obsolete) has 1,155 units available. The ECH-U1H222GX5 (active) has 36,190 units available in tape and reel packaging.

Q: Are there compliance differences between the substitute and main part?

A: The ECH-U1H222GX5 is RoHS3 compliant and REACH unaffected with MSL 1 (unlimited moisture sensitivity level). The main part ECH-S1H222GZ does not list these certifications.

Q: What packaging format is the substitute supplied in?

A: The ECH-U1H222GX5 is supplied in tape and reel (TR) format for automated assembly. The main part ECH-S1H222GZ packaging format is not specified in available data.
