Substitute Part Grouping Explanation

Substitution eligibility for the TAP225M025DTS is determined by the following critical parameters:

• Capacitance Value: Must be 2.2 µF (no deviation permitted)
• Voltage Rating: Must be 25 V or higher
• Package Type: Must be radial through-hole with identical lead spacing (0.098" / 2.50mm)
• Physical Dimensions: Must match 0.177" Dia (4.50mm) and 0.276" (7.00mm) height
• Electrical Characteristics: ESR, operating temperature range, and conformal coating must be maintained
• Compliance: RoHS3 compliance required

The TAP225K025SRW meets all substitution criteria with an improved tolerance specification (±10% versus ±20%), maintaining identical electrical performance and physical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both TAP225M025DTS and TAP225K025SRW are active production components with full ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on the following criteria:

TAP225M025DTS is appropriate when ±20% tolerance meets circuit requirements and tape & box packaging is preferred for specific assembly processes.

TAP225K025SRW is appropriate when tighter capacitance tolerance (±10%) is required for improved circuit performance, or when higher inventory availability (8195 units versus 945 units) supports supply chain continuity. The cut tape packaging format accommodates automated pick-and-place assembly operations.

Both parts maintain identical electrical performance, thermal characteristics, and physical compatibility with existing PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can TAP225K025SRW replace TAP225M025DTS in existing designs?

A: Yes. Both parts share identical capacitance (2.2 µF), voltage rating (25 V), ESR (6 Ohm), operating temperature range (-55°C to 125°C), and physical dimensions. The TAP225K025SRW offers improved tolerance (±10% versus ±20%), making it functionally compatible for direct substitution.

Q: What is the difference between Tape & Box and Cut Tape packaging?

A: Tape & Box (TB) packaging includes a full reel with protective box, suitable for manual assembly or lower-volume production. Cut Tape (CT) packaging provides individual components on tape segments, optimized for automated pick-and-place assembly systems.

Q: Are there any compliance differences between these parts?

A: No. Both TAP225M025DTS and TAP225K025SRW are ROHS3 compliant, REACH unaffected, and carry identical ECCN (EAR99) and HTSUS (8532.21.0040) classifications.

Q: Why would I choose the TAP225M025DTS if TAP225K025SRW has tighter tolerance?

A: The TAP225M025DTS may be selected when ±20% tolerance is acceptable for the application, tape & box packaging is required for specific assembly workflows, or when existing inventory must be utilized before transitioning to substitute stock.

Q: Do these parts have identical thermal performance?

A: Yes. Both parts operate across -55°C to 125°C and maintain 1000 hours lifetime at 85°C, ensuring equivalent reliability in thermal cycling and high-temperature environments.
