TMK105BJ224MP-F Equivalent & Substitute Parts

Part Overview

The TMK105BJ224MP-F is a 0.22 µF ceramic capacitor rated at 25V with X5R temperature coefficient, manufactured by Taiyo Yuden in 0402 (1005 Metric) surface mount package. This component is designated as "Not For New Designs," indicating it has reached end-of-life status. The part is commonly used in SMPS filtering applications where stable capacitance across temperature ranges and voltage stability are required. Due to its obsolescence status, equivalent and substitute parts with compatible electrical and mechanical specifications are necessary for ongoing production support and design continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the TMK105BJ224MP-F is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Capacitance: 0.22 µF (exact match required)
• Voltage Rating: 25V (minimum requirement)
• Package / Case: 0402 (1005 Metric)
• Mounting Type: Surface Mount, MLCC
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: MSL 1

Allowable Variations:

• Temperature Coefficient: X5R or X7R are both acceptable. X7R provides wider operating temperature range (-55°C ~ 125°C versus -55°C ~ 85°C) and tighter tolerance (±10% versus ±20%)
• Packaging Format: Tape & Reel (TR), Cut Tape (CT), or Digi-Reel® formats are interchangeable for component specification purposes, though procurement and assembly processes may differ

Substitute Parts Identified:

1. TMK105BJ224MV-F (Parametric Equivalent): Identical electrical specifications to the main part with different packaging format (Tape & Reel). Same X5R temperature coefficient and ±20% tolerance.

2. TMK105B7224KV-FR (Upgrade Substitute): Enhanced performance variant with X7R temperature coefficient, ±10% tolerance, and extended operating temperature range to 125°C. Packaged in Cut Tape & Digi-Reel® format.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (TMK105BJ224MV-F): Select this part when the original TMK105BJ224MP-F specification must be maintained exactly. This equivalent provides identical electrical performance with X5R temperature coefficient and ±20% tolerance. The difference in packaging format (Tape & Reel) does not affect component performance and is suitable for standard surface mount assembly processes. This part carries the same "Not For New Designs" status and ROHS3 compliance as the main part.

For Performance Enhancement (TMK105B7224KV-FR): Select this upgrade substitute when the application environment or design requirements benefit from improved performance characteristics. The X7R temperature coefficient provides tighter capacitance tolerance (±10% versus ±20%) and extended operating temperature range to 125°C, compared to the X5R specification limited to 85°C. This part is suitable for applications requiring enhanced temperature stability or when operating conditions approach the upper temperature limit of the X5R variant. The Cut Tape & Digi-Reel® packaging format is compatible with automated assembly equipment. This part also carries ROHS3 compliance and MSL 1 rating.

Both substitute parts maintain full compatibility with the 0402 (1005 Metric) PCB footprint and surface mount assembly process. All three parts are manufactured by Taiyo Yuden and carry identical regulatory compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can TMK105BJ224MV-F be used as a direct replacement for TMK105BJ224MP-F?

A: Yes. Both parts have identical electrical specifications: 0.22 µF capacitance, ±20% tolerance, 25V rating, X5R temperature coefficient, and -55°C ~ 85°C operating range. The only difference is packaging format (Tape & Reel for both), which does not affect component performance or PCB compatibility.

Q: What is the difference between X5R and X7R temperature coefficients?

A: X5R maintains capacitance within ±15% across -55°C ~ 85°C operating range with ±20% tolerance specification. X7R maintains capacitance within ±15% across -55°C ~ 125°C operating range with ±10% tolerance specification. X7R provides wider temperature coverage and tighter tolerance, making it suitable for applications with broader environmental requirements.

Q: Is TMK105B7224KV-FR compatible with the same PCB footprint?

A: Yes. TMK105B7224KV-FR uses the same 0402 (1005 Metric) package with identical dimensions (0.039" L x 0.020" W, 0.026" max thickness) and surface mount mounting type. It is directly compatible with existing PCB layouts designed for TMK105BJ224MP-F.

Q: Can I use TMK105B7224KV-FR in place of TMK105BJ224MP-F if my application operates above 85°C?

A: Yes. If the application environment requires operation above 85°C but below 125°C, TMK105B7224KV-FR is the appropriate selection due to its extended operating temperature range. The X7R temperature coefficient ensures stable capacitance performance across this wider range.

Q: Are all three parts ROHS3 compliant?

A: Yes. TMK105BJ224MP-F, TMK105BJ224MV-F, and TMK105B7224KV-FR are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level, meeting current regulatory requirements for electronic components.

Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel® packaging?

A: Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel® are different packaging and delivery formats used during procurement and assembly. Both formats contain the same component and are compatible with standard surface mount assembly equipment. The selection between formats depends on procurement preferences and assembly line requirements, not component performance.

Q: Why is the main part marked "Not For New Designs"?

A: This designation indicates the part has reached end-of-life status and is no longer recommended for new product development. However, it remains available for existing production support and design continuity. The substitute parts listed carry the same status, indicating they are also in end-of-life phase.

Q: Can I mix different substitute parts in the same assembly?

A: Yes. Both TMK105BJ224MV-F and TMK105B7224KV-FR meet the electrical and mechanical requirements for SMPS filtering applications. However, using different temperature coefficient variants (X5R versus X7R) in the same circuit may result in different capacitance behavior across temperature ranges. Design verification is necessary to confirm this approach meets circuit requirements.
