Key Parameters

Substitute Part Grouping Explanation

Substitution of the DMT4P22K is determined by strict equivalence across the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Capacitance value: 0.22 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage rating - DC: 400V (minimum requirement; higher ratings acceptable)
• Voltage rating - AC: 200V (minimum requirement; higher ratings acceptable)
• Dielectric material: Polyester, Metallized (exact match required)
• Operating temperature range: -55°C to 125°C (minimum requirement; wider ranges acceptable)

Mechanical Equivalence Criteria:

• Mounting type: Through Hole (exact match required)
• Package type: Radial (exact match required)
• Lead spacing: 1.169" (29.70mm) (exact match required)
• Termination: PC Pins (exact match required)

Substitute parts must satisfy all electrical and mechanical criteria to ensure direct compatibility without circuit redesign or PCB modification.

Engineering Selection Recommendations

Primary Substitute: DMT4P22K-F

The DMT4P22K-F is the direct equivalent substitute for the obsolete DMT4P22K. Both parts are manufactured by Cornell Dubilier Electronics within the DMT series and share identical electrical specifications (0.22 µF, ±10%, 400V DC, 200V AC) and mechanical dimensions (radial through-hole, 29.70mm lead spacing, PC pin termination).

The key distinction between these parts is product status and regulatory compliance:

• DMT4P22K: Obsolete status with RoHS non-compliant designation
• DMT4P22K-F: Active product status with ROHS3 compliance

The DMT4P22K-F is available in bulk packaging with 913 units in stock, compared to 907 units of the obsolete DMT4P22K. Selection of the DMT4P22K-F ensures access to an actively manufactured component with current regulatory compliance for new designs and ongoing production requirements.

Frequently Asked Questions (FAQ)

Q: Can the DMT4P22K-F be used as a direct replacement for the DMT4P22K?

A: Yes. The DMT4P22K-F is electrically and mechanically equivalent to the DMT4P22K. Both parts have identical capacitance (0.22 µF), tolerance (±10%), voltage ratings (400V DC / 200V AC), dielectric material (polyester metallized), operating temperature range (-55°C to 125°C), and physical dimensions. No circuit modification or PCB redesign is required.

Q: What is the difference between DMT4P22K and DMT4P22K-F?

A: The primary differences are product status and regulatory compliance. The DMT4P22K is obsolete and RoHS non-compliant, while the DMT4P22K-F is an active product with ROHS3 compliance. All electrical and mechanical specifications are identical.

Q: Are there packaging differences between these parts?

A: The DMT4P22K-F is supplied in bulk packaging, whereas the original DMT4P22K packaging specification is listed as a dash (-). Both parts maintain identical physical dimensions and lead spacing (1.169" / 29.70mm), ensuring compatibility with existing PCB layouts.

Q: What compliance certifications apply to the DMT4P22K-F?

A: The DMT4P22K-F carries ROHS3 compliance and REACH Unaffected status. The part is classified under ECCN EAR99 and HTSUS 8532.25.0070.

Q: Can I use the DMT4P22K-F in applications originally designed for the DMT4P22K?

A: Yes. The DMT4P22K-F meets all electrical and mechanical requirements of the original specification. The operating temperature range (-55°C to 125°C), voltage ratings (400V DC / 200V AC), and capacitance value (0.22 µF) are identical, making it suitable for general-purpose applications without modification.
