Key Parameters

Substitute Part Grouping Explanation

Substitution of the TPC1C221MAD is determined by the following critical parameters:

• Capacitance Value: 220 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Physical Package: Axial, Can configuration with 0.315" diameter and 0.787" length (8.00mm x 20.00mm)
• Mounting Type: Through Hole (exact match required)
• Operating Temperature Range: -40°C ~ 105°C (exact match required)
• Voltage Rating: Minimum 16 V (equal or higher voltage rating is acceptable)

The 227TMA035M qualifies as a direct substitute based on matching capacitance, tolerance, physical dimensions, mounting type, and operating temperature range. The higher voltage rating (35 V versus 16 V) provides enhanced reliability margin and is electrically compatible with 16 V circuit requirements.

Engineering Selection Recommendations

The 227TMA035M is the qualified substitute for the obsolete TPC1C221MAD. Selection is based on the following engineering criteria:

Product Status: The main part is obsolete, while the substitute is active and available in production quantities (619 pcs in stock).

Electrical Compatibility: The substitute maintains identical capacitance (220 µF) and tolerance (±20%). The elevated voltage rating (35 V versus 16 V) is compatible with 16 V circuit applications and provides additional safety margin.

Physical Compatibility: Both parts share identical physical dimensions (0.315" diameter x 0.787" length) and axial through-hole mounting configuration, ensuring direct board-level compatibility without layout modifications.

Compliance: The substitute is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. Both parts carry EAR99 classification and identical HTSUS codes (8532.22.0020).

Performance Enhancement: The substitute offers extended lifetime (2000 hours at 105°C versus 1000 hours), providing improved long-term reliability in thermal stress conditions.

Frequently Asked Questions (FAQ)

Q: Can the 227TMA035M directly replace the TPC1C221MAD without circuit modifications?

A: Yes. The substitute maintains identical capacitance, tolerance, physical dimensions, and mounting configuration. Direct board-level substitution is possible without design changes.

Q: Why is the voltage rating higher on the substitute part?

A: The 227TMA035M operates at 35 V rated voltage compared to the original 16 V rating. Higher voltage-rated capacitors are electrically compatible with lower-voltage applications and provide improved reliability margins. No circuit modifications are required.

Q: Are there any thermal performance differences?

A: The substitute offers superior thermal performance with 2000 hours lifetime at 105°C compared to 1000 hours for the original part. This represents a 2x improvement in thermal endurance under identical temperature conditions.

Q: What is the ESR specification for the substitute?

A: The 227TMA035M has an ESR of 1.055 Ohm at 120 Hz. The original part does not specify ESR in the available documentation.

Q: Are both parts through-hole mounted?

A: Yes. Both the TPC1C221MAD and 227TMA035M are through-hole mounted axial capacitors with identical lead spacing and physical footprint.

Q: What compliance certifications apply to the substitute?

A: The 227TMA035M is ROHS3 compliant, REACH unaffected, and carries EAR99 export classification. Moisture sensitivity level is 1 (unlimited).
