Engineering Selection Recommendations

DME1W10K-F (Similar Substitute - Same Voltage Rating)

The DME1W10K-F maintains identical electrical specifications to the DMM1W10K-F with 10 µF capacitance, ±10% tolerance, and 100V DC rating. This substitute is suitable for applications where the original DMM series is unavailable. The DME1W10K-F features reduced physical dimensions (26.00mm x 11.50mm versus 31.00mm x 18.00mm) and shorter lead spacing (22.50mm versus 27.50mm), requiring PCB layout verification for pin-to-pin compatibility. Both components are ROHS3 compliant and Active status. Inventory availability is higher for DME1W10K-F (2366 pcs versus 793 pcs).

DME2W10K-F (Upgrade Substitute - Higher Voltage Rating)

The DME2W10K-F provides upgraded voltage performance at 250V DC (160V AC) while maintaining 10 µF capacitance and ±10% tolerance. This upgrade substitute is applicable in circuits requiring higher voltage margin or operating in elevated voltage environments. Physical dimensions are comparable to the main part (31.00mm x 16.00mm) with identical lead spacing (27.50mm), facilitating direct PCB substitution. ROHS3 compliance and Active status are maintained. This component is suitable for general purpose and EMI/RFI suppression applications.

B32524Q3106K (Upgrade Substitute - Alternative Manufacturer)

The B32524Q3106K is manufactured by EPCOS - TDK Electronics and provides 250V DC (160V AC) voltage rating with 10 µF capacitance and ±10% tolerance. This substitute offers cross-manufacturer compatibility with polyester PET metallized dielectric construction. Physical dimensions (31.50mm x 18.00mm) and lead spacing (27.50mm) are compatible with the main part footprint. ROHS3 compliance and Active status are confirmed. This component is rated for automotive applications and EMI/RFI suppression. Inventory availability is 1008 pcs.

Frequently Asked Questions (FAQ)

Q: Can DME1W10K-F be used as a direct replacement for DMM1W10K-F?

A: The DME1W10K-F is electrically equivalent with identical capacitance (10 µF), tolerance (±10%), and voltage rating (100V DC). However, physical dimensions and lead spacing differ. The DME1W10K-F measures 26.00mm x 11.50mm with 22.50mm lead spacing, compared to the DMM1W10K-F at 31.00mm x 18.00mm with 27.50mm lead spacing. PCB layout verification is required to confirm pin-to-pin compatibility before substitution.

Q: When should I use an upgrade substitute like DME2W10K-F or B32524Q3106K?

A: Upgrade substitutes with 250V DC rating are selected when the circuit operates at higher voltages than the original 100V specification, or when design margin for voltage transients is required. Both upgrade substitutes maintain the 10 µF capacitance and ±10% tolerance while providing enhanced voltage performance. Lead spacing remains compatible (27.50mm) with the main part.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. The DMM1W10K-F and all listed substitute parts (DME1W10K-F, DME2W10K-F, B32524Q3106K) are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the difference between DME1W10K-F and DME2W10K-F?

A: Both are Cornell Dubilier Electronics DME series components with 10 µF capacitance and ±10% tolerance. The DME1W10K-F maintains 100V DC rating (equivalent to the main part), while DME2W10K-F provides upgraded 250V DC rating. Physical dimensions also differ: DME1W10K-F is 26.00mm x 11.50mm, and DME2W10K-F is 31.00mm x 16.00mm.

Q: Can B32524Q3106K be used in automotive applications?

A: Yes. The B32524Q3106K is rated for automotive applications and EMI/RFI suppression. It maintains the same electrical specifications (10 µF, ±10%, 250V DC) as the DME2W10K-F upgrade substitute while offering cross-manufacturer sourcing from EPCOS - TDK Electronics.

Q: What is the lead spacing requirement for through-hole mounting?

A: The main part DMM1W10K-F requires 27.50mm lead spacing. The similar substitute DME1W10K-F uses 22.50mm spacing, requiring PCB layout verification. Both upgrade substitutes (DME2W10K-F and B32524Q3106K) maintain 27.50mm lead spacing, compatible with the original footprint.

Q: Are there inventory considerations when selecting a substitute?

A: Current inventory levels are: DMM1W10K-F (793 pcs), DME1W10K-F (2366 pcs), DME2W10K-F (801 pcs), and B32524Q3106K (1008 pcs). The DME1W10K-F offers the highest availability if supply continuity is a selection criterion.
