DMM1W2P2K-F Film Capacitor Equivalent & Substitute Parts

Part Overview

The DMM1W2P2K-F is a 2.2 µF film capacitor manufactured by Cornell Dubilier Electronics (CDE) in the DMM series. This radial through-hole component operates at 100V DC with polyester metallized dielectric construction and ±10% capacitance tolerance. The part is Active status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent electrical performance is required, when inventory constraints exist, or when design specifications permit higher voltage ratings or alternative packaging configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DMM1W2P2K-F is determined by the following criteria:

Primary Substitution Parameters:

• Capacitance value: 2.2 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Dielectric type: Polyester, Metallized (exact match required)
• Mounting type: Through Hole (exact match required)
• Package type: Radial (exact match required)
• Termination: PC Pins (exact match required)

Secondary Substitution Parameters (Allowable Variations):

• Voltage Rating - DC: Equal to or greater than 100V
• Voltage Rating - AC: Equal to or greater than 65V
• Operating Temperature Range: Equal to or exceeding -55°C to 125°C
• Lead Spacing: 0.886" (22.50 mm) preferred; alternative spacing permitted if PCB layout accommodates
• Physical dimensions: Variations acceptable if board space permits

Manufacturer Flexibility:

• Substitutes from different manufacturers (Cornell Dubilier Electronics, EPCOS - TDK Electronics) are permitted provided all primary parameters match and secondary parameters meet or exceed specifications.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Same Electrical Specifications):

• 160225K100N-F: Identical capacitance, tolerance, voltage rating, and lead spacing. Operates at reduced maximum temperature (105°C vs. 125°C). Suitable for applications where full temperature range is not required. ROHS3 compliant with MSL 1 rating.
• DME1W2P2K-F: Identical electrical specifications and full temperature range. Reduced lead spacing (15.00 mm vs. 22.50 mm) requires PCB layout verification. ROHS3 compliant. Compact form factor alternative.

Upgraded Voltage Rating (Higher DC/AC Voltage Capability):

• DME2W2P2K-F: 250V DC / 160V AC rating provides 2.5× voltage margin over original specification. Identical temperature range and lead spacing. CDE manufacturer continuity. ROHS3 compliant. Suitable for applications requiring enhanced voltage headroom or future design margin.
• B32523Q3225K000: 250V DC / 160V AC rating with EPCOS - TDK manufacturer. Polyethylene Terephthalate (PET) dielectric variant. AEC-Q200 automotive qualification. ROHS3 compliant. Suitable for automotive applications or designs requiring cross-manufacturer sourcing.

Selection Criteria:

• All substitute parts maintain Active product status and ROHS3 compliance.
• Lead spacing compatibility must be verified against PCB layout before selection.
• Temperature range requirements determine suitability of 160225K100N-F (105°C maximum).
• Voltage-upgraded options (DME2W2P2K-F, B32523Q3225K000) are direct functional replacements with enhanced specifications.

Frequently Asked Questions (FAQ)

Q: Can DME2W2P2K-F replace DMM1W2P2K-F in my circuit? A: Yes. DME2W2P2K-F is a direct functional replacement with identical capacitance (2.2 µF), tolerance (±10%), and lead spacing (22.50 mm). The 250V DC rating exceeds the original 100V DC requirement. Both parts share identical operating temperature range (-55°C to 125°C) and ROHS3 compliance.

Q: What is the difference between DME1W2P2K-F and DMM1W2P2K-F? A: Both parts have identical electrical specifications (2.2 µF, ±10%, 100V DC, 65V AC, -55°C to 125°C). The primary difference is lead spacing: DME1W2P2K-F uses 15.00 mm spacing versus 22.50 mm for DMM1W2P2K-F. Physical dimensions are also reduced. Selection depends on PCB layout constraints.

Q: Is 160225K100N-F suitable for high-temperature applications? A: 160225K100N-F operates to 105°C maximum, compared to 125°C for DMM1W2P2K-F. For applications requiring full -55°C to 125°C range, use DMM1W2P2K-F, DME2W2P2K-F, DME1W2P2K-F, or B32523Q3225K000 instead.

Q: Can I use B32523Q3225K000 in place of DMM1W2P2K-F? A: Yes. B32523Q3225K000 is functionally equivalent with 2.2 µF capacitance, ±10% tolerance, and identical lead spacing (22.50 mm). It provides 250V DC rating and AEC-Q200 automotive qualification. EPCOS - TDK manufacturer provides cross-source redundancy.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts (DME2W2P2K-F, 160225K100N-F, DME1W2P2K-F, B32523Q3225K000) are ROHS3 compliant and REACH unaffected, matching the original DMM1W2P2K-F compliance status.

Q: What determines if a part can substitute for DMM1W2P2K-F? A: Primary requirements are exact match on capacitance (2.2 µF), tolerance (±10%), dielectric type (polyester metallized), mounting (through hole), package (radial), and termination (PC pins). Secondary parameters including voltage rating, temperature range, and lead spacing may vary within specified limits.

Q: Does lead spacing affect PCB compatibility? A: Yes. DME1W2P2K-F uses 15.00 mm lead spacing versus 22.50 mm standard spacing. PCB hole pattern must accommodate the selected lead spacing. Verify board layout before substitution.
