Key Parameters

Substitute Part Grouping Explanation

Substitute relationships for the DMM4P47K-F are established based on the following critical parameters that determine functional equivalence:

Primary Equivalence Criteria:

• Capacitance value: 0.47 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Dielectric material: Polyester, Metallized (exact match required)
• Mounting type: Through Hole (exact match required)
• Termination: PC Pins (exact match required)
• Operating temperature range: -55°C to 125°C (exact match required)

Allowable Variation Parameters:

• Voltage rating: Equal to or greater than 400V DC
• Physical dimensions: Variations permitted if lead spacing remains compatible with 0.886" (22.50mm) standard PCB hole patterns
• Series designation: May differ (DMM vs. DME series)
• Packaging format: May differ (tape/reel vs. bulk)

Two substitute parts meet these criteria with distinct substitution classifications:

DME6P47K-F (Upgrade Substitute): Identical electrical specifications with elevated voltage rating (630V DC vs. 400V DC), providing enhanced voltage margin for the same capacitance and tolerance. Maintains identical lead spacing and operating temperature range.

DME4P47K-F (Similar Substitute): Identical electrical specifications and voltage rating (400V DC) with reduced physical footprint. Lead spacing reduced to 0.591" (15.00mm), requiring PCB layout verification for hole pattern compatibility.

Parameter Comparison

Engineering Selection Recommendations

DME6P47K-F Selection Criteria: Select DME6P47K-F when circuit design permits higher voltage rating utilization. This upgrade substitute provides 630V DC rating versus 400V DC on the main part, delivering increased safety margin in high-voltage applications. All electrical parameters (capacitance, tolerance, dielectric material) remain identical. Physical dimensions match the main part exactly with identical lead spacing (0.886" / 22.50mm), ensuring direct PCB compatibility without layout modification. Both parts maintain ROHS3 compliance and REACH unaffected status. Inventory availability is higher (1848 pcs vs. 1017 pcs).

DME4P47K-F Selection Criteria: Select DME4P47K-F when space constraints require reduced physical footprint. This similar substitute maintains identical electrical specifications and voltage rating (400V DC) as the main part. Lead spacing is reduced to 0.591" (15.00mm) from 0.886" (22.50mm), requiring verification that PCB hole patterns accommodate this reduced spacing. Physical dimensions are significantly smaller (0.728" L x 0.327" W vs. 1.024" L x 0.394" W). Both parts maintain ROHS3 compliance and REACH unaffected status. Inventory availability is adequate (1491 pcs).

All three parts are Active product status with full regulatory compliance. Selection between main part and substitutes depends on voltage margin requirements and PCB layout constraints.

Frequently Asked Questions (FAQ)

Q: Can DME6P47K-F replace DMM4P47K-F in any application?

A: DME6P47K-F is electrically and mechanically compatible with DMM4P47K-F for all applications rated at 400V DC or lower. The 630V DC rating of DME6P47K-F provides additional voltage margin. Lead spacing is identical (0.886" / 22.50mm), requiring no PCB modification. All other parameters (capacitance, tolerance, dielectric, temperature range, termination) are identical.

Q: What is the key difference between DME4P47K-F and the main part DMM4P47K-F?

A: DME4P47K-F has reduced physical dimensions and lead spacing (0.591" vs. 0.886"). Electrical specifications and voltage rating are identical. PCB hole pattern compatibility must be verified before substitution, as the reduced lead spacing may not fit existing 0.886" spaced holes.

Q: Are all three parts ROHS3 compliant?

A: Yes. DMM4P47K-F, DME6P47K-F, and DME4P47K-F are all ROHS3 compliant and REACH unaffected.

Q: Can I use DME4P47K-F if my PCB is designed for 0.886" lead spacing?

A: No. DME4P47K-F has 0.591" lead spacing and will not fit PCB holes designed for 0.886" spacing. PCB layout modification is required for this substitution.

Q: What is the operating temperature range for all three parts?

A: All three parts operate across -55°C to 125°C temperature range.

Q: Are there inventory differences between the three parts?

A: Yes. DMM4P47K-F has 1017 pcs in stock, DME6P47K-F has 1848 pcs, and DME4P47K-F has 1491 pcs available.

Q: Do all parts use the same dielectric material?

A: Yes. All three parts use polyester metallized dielectric material with identical ±10% tolerance.
