Substitute Part Grouping Explanation

Substitution of the TMK063BJ223MP-F is determined by strict equivalence across the following critical parameters:

Mandatory Match Criteria:

• Capacitance value: 0.022 µF (exact match required)
• Voltage rating: 25V (substitute must equal or exceed)
• Temperature coefficient: X5R (required for circuit stability)
• Package: 0201 (0603 Metric) (physical and electrical compatibility)
• Operating temperature range: -55°C ~ 85°C (minimum requirement)
• Mounting type: Surface Mount, MLCC (assembly process compatibility)

Acceptable Variation:

• Tolerance: Substitute parts with tighter tolerance (±10%) are acceptable replacements for parts specified at ±20%, as this represents improved capacitance accuracy without affecting circuit design margins.

Compliance Requirements:

• RoHS3 compliance maintained
• MSL rating of 1 (Unlimited) or equivalent

The TMK063BJ223KP-F meets all mandatory criteria and represents a direct functional equivalent with improved tolerance specification.

Parameter Comparison

Engineering Selection Recommendations

The TMK063BJ223KP-F is a direct functional equivalent to the TMK063BJ223MP-F for all circuit design and performance requirements. Both parts share identical electrical specifications, physical dimensions, temperature characteristics, and regulatory compliance status.

Selection Basis:

The substitute part TMK063BJ223KP-F offers the following advantages:

• Improved capacitance tolerance (±10% versus ±20%), resulting in tighter circuit performance margins
• Significantly higher inventory availability (530,778 pieces versus 619 pieces)
• Identical electrical performance in SMPS filtering applications
• Maintained RoHS3 compliance and MSL rating

The primary distinction between the two parts is packaging format: the main part is supplied in Tape & Reel (TR) format, while the substitute is available in Cut Tape (CT) and Digi-Reel® formats. This packaging difference does not affect electrical or mechanical compatibility and is determined by procurement and assembly requirements.

Both parts carry "Not For New Designs" status from Taiyo Yuden, indicating that neither component is recommended for new circuit development. However, for existing designs currently utilizing the TMK063BJ223MP-F, the TMK063BJ223KP-F provides a compatible replacement option.

Frequently Asked Questions (FAQ)

Q: Can the TMK063BJ223KP-F be used as a direct replacement for the TMK063BJ223MP-F in existing circuit designs?

A: Yes. The TMK063BJ223KP-F is electrically and mechanically equivalent to the TMK063BJ223MP-F. Both parts have identical capacitance (0.022 µF), voltage rating (25V), temperature coefficient (X5R), operating temperature range (-55°C ~ 85°C), and physical dimensions (0201 / 0603 Metric package). The substitute part features improved tolerance (±10% versus ±20%), which enhances circuit performance without requiring design modifications.

Q: What is the difference between the packaging formats (Tape & Reel versus Cut Tape & Digi-Reel)?

A: Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel® are different supply formats for the same component. Tape & Reel format supplies components on continuous tape wound on reels, typically used for high-volume automated assembly. Cut Tape format supplies components on tape segments, and Digi-Reel® is a proprietary packaging format. These packaging differences do not affect the electrical or mechanical properties of the capacitor and are selected based on assembly equipment compatibility and procurement preferences.

Q: Why does the substitute part have a tighter tolerance specification?

A: The TMK063BJ223KP-F is specified with ±10% tolerance compared to the ±20% tolerance of the main part. Tighter tolerance represents improved manufacturing precision and capacitance accuracy. This is an acceptable and beneficial variation for substitution purposes, as it provides better circuit performance without introducing any compatibility issues.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the TMK063BJ223MP-F and TMK063BJ223KP-F are ROHS3 compliant and carry identical regulatory certifications (ECCN: EAR99, HTSUS: 8532.24.0020).

Q: What does "Not For New Designs" product status mean?

A: "Not For New Designs" indicates that Taiyo Yuden has discontinued active development and promotion of this component series. This status applies to both the main part and the substitute part. For new circuit development, alternative capacitor models from current product lines should be evaluated. However, for existing designs and production support, both parts remain available for use.

Q: Is the moisture sensitivity level the same for both parts?

A: Yes. Both parts have MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage and handling. This simplifies logistics and eliminates special environmental controls during component storage and assembly.

Q: Can the TMK063BJ223KP-F be used in SMPS filtering applications?

A: Yes. Both parts are specified for SMPS filtering applications. The electrical characteristics, voltage rating, and temperature stability of the TMK063BJ223KP-F make it suitable for all SMPS filtering applications where the main part was originally specified.
