Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ECD-G0ER408 are qualified based on the following electrical and mechanical parameters:

• Capacitance: Must be 0.4 pF
• Tolerance: Must be ±0.05pF
• Temperature Coefficient: Must be C0G or NP0
• Operating Temperature Range: Must support -55°C ~ 125°C
• Package / Case: Must be 0402 (1005 Metric)
• Mounting Type: Must be Surface Mount, MLCC
• Voltage Rating: Substitute parts may have equal or higher voltage ratings (25V or greater)

Five active substitute parts meet these criteria across multiple manufacturers, providing design flexibility while maintaining electrical and mechanical compatibility with the original specification.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are active products with current manufacturing status, ensuring long-term availability and supply chain stability. The original ECD-G0ER408 is obsolete and should be replaced in new designs.

Voltage Rating Considerations: The original part is rated at 25V. All substitute parts maintain equal or higher voltage ratings (50V, 100V, or 200V), providing design margin and compatibility with existing circuit requirements. Higher voltage ratings do not degrade performance in applications designed for lower voltages.

Compliance and Certifications: All substitute parts are RoHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components. All parts carry EAR99 export classification and HTSUS code 8532.24.0020.

Inventory Availability: Substitute parts are available in quantities ranging from 713 to 52,687 pieces, with the highest availability from Johanson Technology (QSCF500Q0R4A1GV001T at 52,687 Pcs) and American Technical Ceramics (600L0R4AT200T4K at 22,315 Pcs).

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with a higher voltage rating than the original 25V specification?

A: Yes. Substitute parts with 50V, 100V, or 200V ratings are electrically compatible. Higher voltage ratings provide additional design margin and do not negatively impact circuit performance in applications specified for 25V operation.

Q: Are all substitute parts mechanically compatible with the original 0402 package footprint?

A: Yes. All substitute parts use the 0402 (1005 Metric) package with identical mounting type (Surface Mount, MLCC). Physical dimensions are equivalent, with minor variations in thickness (0.022" to 0.024") that do not affect PCB assembly or clearance.

Q: What is the difference between C0G and NP0 temperature coefficients?

A: C0G and NP0 designations refer to the same temperature coefficient characteristic. Both terms describe capacitors with negligible capacitance change across the operating temperature range (-55°C ~ 125°C). The terms are manufacturer-specific nomenclature for identical electrical behavior.

Q: Which substitute part offers the best inventory availability?

A: QSCF500Q0R4A1GV001T from Johanson Technology Inc. has the highest inventory level at 52,687 pieces, followed by 600L0R4AT200T4K from American Technical Ceramics at 22,315 pieces.

Q: Are all substitute parts suitable for RF and microwave applications?

A: Yes. All substitute parts are specified for RF, microwave, and high-frequency applications with high Q and low-loss characteristics, matching the original part's intended use.

Q: What packaging options are available for substitute parts?

A: Substitute parts are available in Tape & Reel (TR) and Cut Tape (CT) packaging formats. Selection depends on production volume and assembly process requirements.
