ECH-S1H683JZ Equivalent & Substitute Parts

Part Overview

The ECH-S1H683JZ is a 0.068 µF 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 product is currently obsolete, making equivalent substitutes necessary for ongoing system maintenance, repairs, and legacy equipment support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ECH-S1H683JZ requires matching the following critical electrical and mechanical parameters:

Electrical Compatibility:

• Capacitance value: 0.068 µF (exact match required)
• DC voltage rating: minimum 50V
• Dielectric material: Polyphenylene Sulfide (PPS) or equivalent
• Operating temperature range: must encompass -40°C ~ 125°C

Mechanical Compatibility:

• Physical dimensions and mounting footprint must accommodate the application's PCB layout
• Lead spacing and termination type must be compatible with existing circuit board design

The ECH-U1H683GX9 qualifies as a functional equivalent based on matching capacitance, voltage rating, dielectric material, and operating temperature specifications. However, this substitute introduces a critical mechanical difference: it is a surface-mount component (1913 package) versus the original through-hole radial design. This substitution is viable only when PCB redesign or adapter solutions are feasible.

Engineering Selection Recommendations

The ECH-U1H683GX9 is the designated substitute for the obsolete ECH-S1H683JZ based on electrical parameter alignment and active product status. Selection of this substitute requires evaluation of the following factors:

Advantages of ECH-U1H683GX9:

• Active product status ensures long-term availability and supply chain continuity
• Tighter tolerance (±2% versus ±5%) provides improved circuit performance
• Extended lower operating temperature limit (-55°C versus -40°C) expands environmental operating range
• RoHS3 compliance and REACH unaffected status meet modern regulatory requirements
• Moisture sensitivity level 1 (unlimited) eliminates moisture-related handling constraints

Implementation Considerations:

• Surface-mount package requires PCB redesign or adapter implementation
• Significantly smaller physical footprint (4.80mm x 3.30mm versus 14.50mm x 5.00mm) necessitates layout modifications
• Solder pad termination replaces through-hole PC pins, requiring different assembly processes

Frequently Asked Questions (FAQ)

Q: Can the ECH-U1H683GX9 be used as a direct drop-in replacement for the ECH-S1H683JZ?

A: No. While both components share identical capacitance (0.068 µF) and DC voltage rating (50V), the ECH-U1H683GX9 is a surface-mount component with a 1913 package, whereas the ECH-S1H683JZ is a through-hole radial component. Direct substitution requires PCB redesign or mechanical adapter solutions.

Q: What are the key electrical parameters that must match for substitution?

A: Capacitance value (0.068 µF), DC voltage rating (minimum 50V), dielectric material (Polyphenylene Sulfide), and operating temperature range (-40°C ~ 125°C minimum) must be maintained for functional equivalence.

Q: Does the ECH-U1H683GX9 have better performance specifications than the ECH-S1H683JZ?

A: The ECH-U1H683GX9 offers tighter tolerance (±2% versus ±5%), extended lower temperature operation (-55°C versus -40°C), and improved regulatory compliance (RoHS3, REACH unaffected). These represent performance enhancements within the same functional category.

Q: What is the significance of the different dielectric descriptions?

A: Both components use Polyphenylene Sulfide (PPS) dielectric material. The ECH-U1H683GX9 specifies "Metallized - Stacked" construction, which is a manufacturing variant that does not affect electrical compatibility for this application.

Q: Are there any packaging or handling differences between these components?

A: The ECH-S1H683JZ uses PC pin termination for through-hole assembly. The ECH-U1H683GX9 uses solder pads for surface-mount assembly. The ECH-U1H683GX9 has moisture sensitivity level 1 (unlimited), eliminating moisture-related storage constraints present in some film capacitors.
