Key Parameters

Substitute Part Grouping Explanation

The DMT1S22K-F is classified as a direct equivalent substitute based on the following critical parameters:

Electrical Parameters:

• Capacitance: 0.022 µF (identical)
• Tolerance: ±10% (identical)
• Voltage Rating - DC: 100V (identical)
• Voltage Rating - AC: 65V (identical)
• Dielectric Material: Polyester, Metallized (identical)
• Operating Temperature Range: -55°C ~ 125°C (identical)

Mechanical Parameters:

• Mounting Type: Through Hole (identical)
• Package / Case: Radial (identical)
• Size / Dimension: 0.512" L x 0.256" W (13.00mm x 6.50mm) (identical)
• Height - Seated (Max): 0.484" (12.30mm) (identical)
• Termination: PC Pins (identical)
• Lead Spacing: 0.394" (10.00mm) (identical)

The substitution is valid because all allowed electrical and mechanical parameters match exactly between the main part and the substitute.

Parameter Comparison

Engineering Selection Recommendations

The DMT1S22K-F is the appropriate selection for new designs and ongoing production requirements. While the DMT1S22K remains electrically and mechanically equivalent, its obsolete status necessitates transition to the active DMT1S22K-F. The DMT1S22K-F provides ROHS3 compliance, whereas the original part is RoHS non-compliant. Both parts share identical REACH unaffected status and EAR99 ECCN classification. The substitution maintains full functional equivalence while providing access to current inventory and improved regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Are the DMT1S22K and DMT1S22K-F electrically interchangeable? A: Yes. Both components have identical capacitance (0.022 µF), tolerance (±10%), DC voltage rating (100V), AC voltage rating (65V), and dielectric material (Polyester, Metallized). Operating temperature ranges are identical (-55°C ~ 125°C).

Q: Are the mechanical dimensions identical? A: Yes. Both parts have identical through-hole radial package dimensions: 0.512" L x 0.256" W (13.00mm x 6.50mm), maximum seated height of 0.484" (12.30mm), PC pin terminations, and 0.394" (10.00mm) lead spacing.

Q: What is the primary difference between these part numbers? A: The DMT1S22K is obsolete, while the DMT1S22K-F is active. The substitute part offers ROHS3 compliance compared to the non-compliant status of the original.

Q: Can I use DMT1S22K-F as a replacement in existing assemblies? A: Yes. The DMT1S22K-F is a direct mechanical and electrical substitute suitable for both new designs and legacy assembly upgrades.

Q: Are there packaging differences? A: The DMT1S22K is listed with standard packaging, while the DMT1S22K-F is available in bulk packaging. Both maintain identical component specifications.
