Key Parameters

Substitute Part Grouping Explanation

Substitution of the ECH-S1H102GZ is determined by the following critical electrical and mechanical parameters:

• Capacitance Value: 1000 pF (exact match required)
• Tolerance: ±2% (maintains circuit performance specifications)
• Voltage Rating - DC: 50V minimum (ensures safe operation margin)
• Dielectric Material: Polyphenylene Sulfide (PPS) (maintains frequency response and stability characteristics)
• Operating Temperature Range: Must support -40°C ~ 125°C minimum
• Mounting Type: Surface mount alternatives acceptable when circuit board design permits

The ECH-U1H102GX5 qualifies as a substitute based on matching capacitance, tolerance, voltage rating, dielectric material, and operating temperature specifications. The transition from radial through-hole to 0805 surface-mount packaging represents a design evolution within the same product family, with the substitute offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

The ECH-U1H102GX5 is the designated substitute for the obsolete ECH-S1H102GZ. Both components share identical electrical specifications: 1000 pF capacitance, ±2% tolerance, 50V DC rating, and PPS dielectric material. The substitute maintains compliance with EAR99 export classification and HTSUS commodity code alignment.

The primary design consideration is the transition from through-hole radial to surface-mount 0805 packaging. This substitution is applicable to new designs or board revisions that accommodate surface-mount technology. The ECH-U1H102GX5 offers extended lower operating temperature capability (-55°C versus -40°C) and active product status with established supply chain availability (58,124 units in stock versus 765 units for the obsolete part).

The substitute's metallized-stacked PPS construction provides equivalent electrical performance for high-frequency and switching applications while delivering improved manufacturing consistency through active production status.

Frequently Asked Questions (FAQ)

Q: Can the ECH-U1H102GX5 directly replace the ECH-S1H102GZ in existing assemblies?

A: Direct board-level replacement is not possible due to packaging differences. The ECH-S1H102GZ uses radial through-hole termination, while the ECH-U1H102GX5 uses surface-mount solder pads. Board redesign or adapter solutions are required for retrofit applications.

Q: Are the electrical characteristics identical between these two parts?

A: Yes. Both components provide 1000 pF capacitance at ±2% tolerance with 50V DC rating and PPS dielectric material. Operating temperature range for the substitute extends to -55°C, exceeding the original part's -40°C lower limit.

Q: What is the significance of the metallized-stacked construction in the substitute?

A: The ECH-U1H102GX5 uses metallized-stacked PPS technology, which is a manufacturing advancement over the original radial design. This construction method maintains electrical performance while enabling the compact 0805 form factor and improving production consistency.

Q: Are there compliance or certification differences between the parts?

A: Both parts share identical ECCN (EAR99) and HTSUS (8532.25.0010) classifications. The substitute achieves ROHS3 compliance and REACH unaffected status, reflecting its active product status.

Q: What packaging format does the substitute use?

A: The ECH-U1H102GX5 is supplied in 0805 (2012 Metric) surface-mount package with tape and reel (TR) packaging. Physical dimensions are 2.00mm length × 1.25mm width × 1.10mm maximum height.
