Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MSAST32MSB7226MPNB25 is determined by the following critical parameters:

Electrical Parameters (Must Match):

• Capacitance: 22 µF
• Tolerance: ±20%
• Voltage Rating: 25V
• Temperature Coefficient: X7R
• Operating Temperature Range: -55°C to 125°C

Mechanical Parameters (Must Match):

• Package / Case: 1210 (3225 Metric)
• Physical Dimensions: 0.126" L x 0.098" W (3.20mm x 2.50mm)
• Thickness (Max): 0.106" (2.70mm)
• Mounting Type: Surface Mount, MLCC

Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The substitute parts identified below meet all electrical, mechanical, and compliance requirements. Variations in product status, packaging format (Tape & Reel versus Cut Tape), and application focus do not affect functional interchangeability in circuit design.

Engineering Selection Recommendations

Primary Selection: MSAST32MSB7226MPNB25

The MSAST32MSB7226MPNB25 is the recommended choice for new designs. This part carries Active product status, indicating ongoing manufacturer support and availability. It is supplied in Tape & Reel (TR) packaging, which is standard for automated assembly processes.

Alternative Selection: TMK325B7226MM-PR

The TMK325B7226MM-PR is a parametric equivalent suitable for applications where the primary part is unavailable. This part meets all electrical and mechanical specifications. It is supplied in Tape & Reel (TR) packaging, matching the primary part's packaging format. Although marked as Not For New Designs, it remains functionally compatible for existing designs or where inventory constraints require substitution.

Alternative Selection: TMK325B7226MMHP

The TMK325B7226MMHP is a parametric equivalent with AEC-Q200 automotive qualification. This part meets all electrical and mechanical specifications and is suitable for applications requiring automotive-grade reliability. It is supplied in Cut Tape (CT) & Digi-Reel® packaging, which may require process adjustment in automated assembly environments. Although marked as Not For New Designs, it remains functionally compatible for existing designs or where automotive compliance is required.

Compliance Considerations:

All three parts are ROHS3 Compliant, REACH Unaffected, and classified under ECCN EAR99. All parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements during storage or assembly.

Frequently Asked Questions (FAQ)

Q: Can TMK325B7226MMHP be used as a direct replacement for MSAST32MSB7226MPNB25?

A: Yes. Both parts are electrically and mechanically identical with matching capacitance (22 µF), voltage rating (25V), temperature coefficient (X7R), package dimensions (1210 / 3225 Metric), and compliance certifications. The primary difference is packaging format: TMK325B7226MMHP uses Cut Tape (CT) & Digi-Reel® while MSAST32MSB7226MPNB25 uses Tape & Reel (TR). Assembly equipment compatibility must be verified for the Cut Tape format.

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

A: Tape & Reel (TR) is a continuous reel format suitable for high-speed automated pick-and-place assembly. Cut Tape (CT) & Digi-Reel® is a shorter tape segment format, typically used for lower-volume applications or manual assembly. Both formats contain identical components; the difference is in supply format and assembly process compatibility.

Q: Why are TMK325B7226MMHP and TMK325B7226MM-PR marked as "Not For New Designs"?

A: Product status reflects manufacturer lifecycle management. Parts marked "Not For New Designs" are in mature or declining production phases but remain available for existing applications. For new designs, MSAST32MSB7226MPNB25 (Active status) is the recommended choice. However, the substitute parts remain functionally equivalent and may be used when the primary part is unavailable.

Q: Does TMK325B7226MMHP's AEC-Q200 rating affect compatibility?

A: No. AEC-Q200 is an automotive qualification standard that indicates additional reliability testing and quality assurance. A part with AEC-Q200 certification can be used in any application where a non-certified equivalent is acceptable. The electrical and mechanical specifications remain identical.

Q: Are there any thermal or frequency performance differences between these parts?

A: No. All three parts share identical temperature coefficient (X7R), operating temperature range (-55°C to 125°C), and physical construction. X7R temperature coefficient ensures stable capacitance across the operating temperature range with minimal variation.

Q: Can these parts be used interchangeably in existing PCB designs?

A: Yes. All three parts have identical package dimensions (1210 / 3225 Metric), footprint, and mounting type (Surface Mount, MLCC). No PCB layout modifications are required for substitution.
