Key Parameters

Substitute Part Grouping Explanation

Substitution of the QMJ212KB7222MDHT is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance value: 2200 pF
• Tolerance: ±20%
• Voltage rating: 250V
• Temperature coefficient: X7R
• Operating temperature range: -55°C ~ 125°C

Mechanical Parameters:

• Package type: 0805 (2012 Metric)
• Mounting type: Surface Mount, MLCC
• Physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm)
• Maximum thickness: 0.039" (1.00mm)
• Soft termination feature

Compliance & Certification:

• AEC-Q200 rating
• ROHS3 compliance
• Moisture Sensitivity Level 1

Parts meeting all these parameters are classified as direct parametric equivalents and may be substituted without circuit redesign or board layout modification.

Parameter Comparison

Engineering Selection Recommendations

The CGA4F3X7R2E222M085AE manufactured by TDK Corporation is a direct parametric equivalent to the QMJ212KB7222MDHT. Both parts share identical electrical specifications, mechanical dimensions, and compliance certifications.

Selection Basis:

The TDK part is classified as Active product status, whereas the Taiyo Yuden original is designated Not For New Designs. This distinction indicates that the TDK equivalent maintains current manufacturing support and availability through standard distribution channels.

Both parts carry AEC-Q200 automotive qualification and ROHS3 compliance, confirming suitability for automotive and industrial applications requiring high reliability standards. The identical moisture sensitivity level (MSL 1) and soft termination feature ensure compatibility with existing assembly processes and environmental requirements.

The parametric equivalence across all electrical, mechanical, and thermal specifications permits direct substitution in applications originally designed for the QMJ212KB7222MDHT without circuit modification or performance degradation.

Frequently Asked Questions (FAQ)

Q: Can the CGA4F3X7R2E222M085AE be used as a direct replacement for QMJ212KB7222MDHT?

A: Yes. Both parts are parametrically equivalent across all critical specifications: 2200 pF capacitance, ±20% tolerance, 250V rating, X7R temperature coefficient, -55°C to 125°C operating range, 0805 package, and identical physical dimensions. No circuit redesign is required.

Q: Are there any differences in compliance or certification between these parts?

A: Both parts are AEC-Q200 rated, ROHS3 compliant, and carry MSL 1 moisture sensitivity level. The TDK part includes REACH Unaffected status. No compliance gaps exist between the two parts.

Q: What is the significance of the "Not For New Designs" status on the Taiyo Yuden part?

A: This designation indicates the manufacturer has discontinued active development and promotion of this part number. The TDK equivalent, classified as Active, represents the current production alternative with ongoing manufacturer support.

Q: Will the 0805 package dimensions be identical for both parts?

A: Yes. Both parts conform to 0805 (2012 Metric) package specifications with identical length (0.079"), width (0.049"), and maximum thickness (0.039"). Board layout and pick-and-place programming require no modification.

Q: Are soft termination features identical between both parts?

A: Yes. Both parts incorporate soft termination, ensuring compatibility with existing assembly processes and boardflex-sensitive applications.

Q: What is the inventory status for each part?

A: The QMJ212KB7222MDHT has 1146 pieces in stock. The CGA4F3X7R2E222M085AE has 886 pieces in stock. Availability should be confirmed with your component supplier for current procurement timelines.
