Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DMT2S47K-F is determined by strict adherence to the following electrical and mechanical criteria:

Electrical Equivalence Requirements:

• Capacitance value must be 0.047 µF
• Tolerance must be ±10% or tighter
• DC voltage rating must be 250V minimum
• AC voltage rating must be 125V minimum (160V acceptable for substitutes)
• Dielectric material must be polyester-based (polyester or polyethylene terephthalate)
• Operating temperature range must span -55°C to 125°C

Mechanical Compatibility Requirements:

• Mounting type must be Through Hole
• Package configuration must be Radial
• Termination must be PC Pins
• RoHS3 compliance must be maintained

Acceptable Variations:

• Physical dimensions may differ (length, width, height, lead spacing) provided the component fits within the available PCB space
• Packaging format may vary (Bulk, Cut Tape) based on manufacturing requirements
• Manufacturer may differ provided all electrical and mechanical specifications are met

All five substitute parts listed meet these criteria and are therefore electrically and mechanically interchangeable with the DMT2S47K-F.

Parameter Comparison

Engineering Selection Recommendations

All five substitute parts maintain Active product status and ROHS3 compliance, ensuring long-term availability and regulatory conformance equivalent to the DMT2S47K-F.

DME2S47K-F (Cornell Dubilier Electronics): This substitute offers the closest manufacturer alignment, maintaining CDE as the source. The part is electrically identical with increased AC voltage rating (160V vs. 125V). Physical dimensions are significantly smaller, with reduced lead spacing (0.295" vs. 0.543"). Selection is appropriate when space constraints exist and lead spacing compatibility with PCB layout is confirmed.

B32521C3473K000 (EPCOS - TDK Electronics): This substitute provides intermediate physical dimensions with lead spacing of 0.394" (10.00mm). The stacked metallized construction offers equivalent electrical performance. This part is rated for automotive applications with AEC-Q200 certification. Selection is appropriate for general-purpose applications where the intermediate form factor accommodates existing PCB designs.

B32529C3473K000 (EPCOS - TDK Electronics, Bulk Packaging): This substitute features the smallest physical footprint with lead spacing of 0.197" (5.00mm) and is available in Bulk packaging. The stacked metallized construction and AEC-Q200 rating provide automotive-grade reliability. Selection is appropriate for space-constrained designs and high-volume manufacturing requiring bulk packaging.

B32529C3473K189 (EPCOS - TDK Electronics, Cut Tape Packaging): Electrically and mechanically identical to B32529C3473K000, this variant differs only in packaging format (Cut Tape vs. Bulk). Selection is appropriate for automated pick-and-place assembly processes requiring tape-and-reel format.

B32529C3473K289 (EPCOS - TDK Electronics, Cut Tape Packaging): Electrically and mechanically identical to B32529C3473K189, this variant maintains the same specifications. Selection is appropriate for automated assembly processes with identical performance characteristics to the B32529C3473K189.

Frequently Asked Questions (FAQ)

Q: Can the DME2S47K-F replace the DMT2S47K-F directly on the PCB?

A: Electrical substitution is valid. However, the DME2S47K-F has significantly different physical dimensions and lead spacing (0.295" vs. 0.543"). Direct PCB replacement requires verification that the smaller component fits within the available space and that lead spacing aligns with PCB pad layout. If the original PCB design accommodates the larger DMT2S47K-F, the smaller DME2S47K-F will fit, but the reverse is not necessarily true.

Q: What is the difference between the B32529C3473K000, B32529C3473K189, and B32529C3473K289 parts?

A: These three parts are electrically and mechanically identical. The primary difference is packaging format: B32529C3473K000 is supplied in Bulk packaging, while B32529C3473K189 and B32529C3473K289 are supplied in Cut Tape (CT) format. Selection depends on manufacturing process requirements. Bulk packaging is suitable for manual assembly or bin-based pick systems. Cut Tape format is required for automated pick-and-place equipment.

Q: Are all substitute parts suitable for automotive applications?

A: The EPCOS - TDK Electronics parts (B32521C3473K000, B32529C3473K000, B32529C3473K189, B32529C3473K289) carry AEC-Q200 automotive qualification and are rated for automotive applications. The Cornell Dubilier parts (DMT2S47K-F and DME2S47K-F) are rated for general-purpose applications. If automotive qualification is a design requirement, selection must be limited to the EPCOS - TDK Electronics substitutes.

Q: What does "stacked metallized" construction mean compared to standard metallized polyester?

A: Both construction types use polyester dielectric material with metallized electrodes. The stacked configuration in EPCOS parts refers to the internal layer arrangement, which provides equivalent electrical performance to the standard metallized construction in CDE parts. From an electrical standpoint, both deliver identical capacitance, voltage rating, and tolerance specifications.

Q: Can I use a substitute part with a higher AC voltage rating (160V vs. 125V)?

A: Yes. A substitute part with a higher voltage rating (160V AC) is electrically compatible with a design specified for 125V AC. The higher rating provides additional safety margin. This substitution does not compromise circuit performance or reliability.

Q: What is the impact of different lead spacing on PCB compatibility?

A: Lead spacing determines the distance between component pins on the PCB. The DMT2S47K-F has 0.543" (13.80mm) spacing, while substitutes range from 0.197" to 0.394". If the original PCB is designed for 0.543" spacing, a substitute with different spacing will not align with existing pads. PCB redesign or adapter solutions would be required. Conversely, if design flexibility exists, smaller lead spacing allows for more compact PCB layouts.

Q: Are all parts RoHS3 compliant?

A: Yes. All parts listed, including the main part DMT2S47K-F and all five substitutes, maintain ROHS3 compliance. This ensures regulatory conformance for applications subject to RoHS directives.

Q: Which substitute offers the best inventory availability?

A: B32529C3473K000 has the highest inventory level at 13,781 units in stock, followed by B32529C3473K189 with 14,083 units. Both EPCOS - TDK Electronics parts provide substantial stock levels for high-volume procurement requirements.
