ECH-S1H562JZ Equivalent & Substitute Parts

Part Overview

The ECH-S1H562JZ is a 5600 pF film capacitor manufactured by Panasonic Electronic Components, rated for 50V DC operation with ±5% 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 identification of suitable substitute components essential for ongoing system support, maintenance, and new production alternatives.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ECH-S1H562JZ is determined by the following critical parameters:

• Capacitance Value: Must be 5600 pF (no tolerance deviation acceptable for functional equivalence)
• Voltage Rating: Minimum 50V DC to maintain electrical safety margins
• Dielectric Material: Polyphenylene sulfide (PPS) to preserve frequency response and thermal stability characteristics
• Operating Temperature Range: Must support the -40°C ~ 125°C envelope or equivalent
• Tolerance: ±5% or tighter (±2% is acceptable as a superior alternative)

The ECH-U1H562GX5 qualifies as a functional equivalent based on matching capacitance, voltage rating, dielectric material, and operating temperature specifications. However, this substitute introduces a change in mounting technology from through-hole radial to surface-mount 1206 package, which requires circuit board redesign and assembly process modification.

Parameter Comparison

Engineering Selection Recommendations

The ECH-U1H562GX5 provides electrical equivalence to the obsolete ECH-S1H562JZ with the following considerations:

Advantages of ECH-U1H562GX5:

• Active product status ensures long-term availability and supply chain continuity
• Tighter tolerance (±2% vs. ±5%) improves circuit performance precision
• Extended lower temperature rating (-55°C vs. -40°C) broadens operational envelope
• ROHS3 compliance supports modern manufacturing and environmental standards
• Higher inventory availability (6189 pcs vs. 666 pcs) reduces procurement lead time

Design Constraints:

• Mounting technology transition from through-hole to surface-mount requires printed circuit board redesign
• Assembly process modification necessary; through-hole soldering equipment cannot be used
• Physical footprint change from radial to 1206 package affects board layout and component density
• Lead spacing elimination (5.00mm to solder pads) requires new PCB trace routing

Direct through-hole replacement is not available from the provided substitute list. Selection of ECH-U1H562GX5 is appropriate only when circuit board redesign is feasible or planned.

Frequently Asked Questions (FAQ)

Q: Can ECH-U1H562GX5 be used as a direct drop-in replacement for ECH-S1H562JZ?

A: No. The ECH-U1H562GX5 is a surface-mount 1206 package component, while the ECH-S1H562JZ is a through-hole radial component. Direct substitution requires printed circuit board redesign and assembly process modification.

Q: What are the critical electrical parameters for substitution?

A: Capacitance (5600 pF), voltage rating (50V DC minimum), dielectric material (PPS), and operating temperature range (-40°C ~ 125°C minimum) must be maintained. Tolerance can be equal or tighter than ±5%.

Q: Does the ECH-U1H562GX5 meet the same voltage and temperature specifications?

A: Yes. The ECH-U1H562GX5 meets or exceeds all voltage and temperature requirements: 50V DC rating and -55°C ~ 125°C operating range (compared to -40°C ~ 125°C for the main part).

Q: What is the significance of the tolerance difference (±5% vs. ±2%)?

A: The ±2% tolerance of ECH-U1H562GX5 provides tighter capacitance control, resulting in improved circuit performance and reduced variation in frequency response and filtering characteristics.

Q: Are there compliance differences between the two parts?

A: Yes. The ECH-U1H562GX5 is ROHS3 compliant and REACH unaffected, while the ECH-S1H562JZ compliance status is not specified. This makes ECH-U1H562GX5 suitable for modern manufacturing environments with environmental regulations.

Q: Why is the ECH-S1H562JZ marked as obsolete?

A: Panasonic has discontinued this through-hole radial film capacitor in favor of surface-mount alternatives. The ECH-U1H562GX5 represents the active product line continuation for this capacitance value and voltage rating.
