Key Parameters

Substitute Part Grouping Explanation

The DMM6P22K-F is substitutable for the obsolete DMM6P22K based on the following matching parameters:

• Capacitance: Identical at 0.22 µF
• Tolerance: Identical at ±10%
• Voltage Rating: Identical at 630V DC / 250V AC
• Dielectric Material: Identical polyester metallized composition
• Operating Temperature Range: Identical at -55°C ~ 125°C
• Mounting Type: Identical through-hole radial configuration
• Physical Dimensions: Identical footprint (26.00mm L x 11.00mm W, 20.00mm seated height, 22.50mm lead spacing)
• Termination: Identical PC pins

The DMM6P22K-F additionally references secondary substitutes (DME10P22K-F, QXK2J224KTPTZH, DME6P22K-F) which share the core electrical parameters required for functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

The DMM6P22K-F is the primary substitution path for the obsolete DMM6P22K. Both parts are electrically and mechanically identical across all functional parameters, with direct footprint compatibility for through-hole PCB designs.

The DMM6P22K-F offers enhanced compliance status with ROHS3 certification, addressing regulatory requirements for new designs and manufacturing environments where RoHS compliance is mandatory. The original DMM6P22K is classified as non-compliant, making the DMM6P22K-F the preferred selection for applications requiring current compliance standards.

Both parts maintain identical performance characteristics across all specified operating conditions, including the full temperature range of -55°C to 125°C and rated electrical parameters.

Frequently Asked Questions (FAQ)

Q: What is the primary difference between DMM6P22K and DMM6P22K-F? A: The DMM6P22K-F is the active production equivalent with ROHS3 compliance certification. The original DMM6P22K is obsolete and non-compliant with current RoHS standards. Electrical and mechanical specifications are identical.

Q: Is the DMM6P22K-F a drop-in replacement for DMM6P22K? A: Yes. The DMM6P22K-F provides identical electrical performance and physical footprint, enabling direct substitution in through-hole PCB designs without circuit modification or layout changes.

Q: What are the lead spacing and PCB footprint requirements? A: The radial configuration specifies 22.50mm (0.886") lead spacing with a maximum seated height of 20.00mm. These dimensions are identical across both parts.

Q: Are there any compliance differences that affect part selection? A: The DMM6P22K-F carries ROHS3 compliance certification, while the original DMM6P22K is non-compliant. For new designs or applications with regulatory requirements, DMM6P22K-F is the appropriate selection.

Q: What are the secondary substitutes referenced for the DMM6P22K-F? A: The DMM6P22K-F document references DME10P22K-F, QXK2J224KTPTZH, and DME6P22K-F as additional substitutes. These alternatives share the core electrical parameters (0.22 µF, ±10% tolerance, 630V DC rating, polyester metallized dielectric) required for functional equivalence.

Q: What is the temperature operating range for these capacitors? A: Both the DMM6P22K and DMM6P22K-F operate across a temperature range of -55°C to 125°C, suitable for industrial and commercial applications.
