Key Parameters

Substitute Part Grouping Explanation

Substitution of the DME1W5P6K is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 5.6 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage Rating - DC: 100V (minimum requirement; higher ratings acceptable)
• Voltage Rating - AC: 65V (minimum requirement; higher ratings acceptable)
• Dielectric Material: Polyester, Metallized (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial (exact match required)
• Lead Spacing: 0.886" (22.50mm) (exact match required for PCB compatibility)
• Termination: PC Pins (exact match required)

Substitute parts must satisfy all parameters listed above without deviation. Product status and compliance certifications are secondary considerations that do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The DME1W5P6K-F is a direct electrical and mechanical equivalent to the obsolete DME1W5P6K. All critical parameters—capacitance, tolerance, voltage ratings, dielectric material, temperature range, mounting configuration, and lead spacing—are identical between the two parts.

The primary distinction is product status: DME1W5P6K-F is an active part with current manufacturing support, whereas DME1W5P6K is obsolete. Additionally, DME1W5P6K-F carries ROHS3 compliance certification, whereas the original part is RoHS non-compliant. Both parts maintain REACH Unaffected status and EAR99 export classification.

For new designs or component replacement in existing systems, DME1W5P6K-F is the appropriate selection. The active product status ensures continued availability and supply chain reliability. The improved RoHS compliance of the substitute part aligns with current environmental and regulatory standards without compromising electrical performance or mechanical fit.

Frequently Asked Questions (FAQ)

Q: Can DME1W5P6K-F be used as a direct replacement for DME1W5P6K in existing circuit boards?

A: Yes. The DME1W5P6K-F is a direct replacement. All electrical parameters (capacitance, tolerance, voltage ratings, temperature range) and mechanical parameters (package type, lead spacing, dimensions, termination) are identical. The component will function identically in the same PCB footprint without modification.

Q: What is the difference between DME1W5P6K and DME1W5P6K-F?

A: The parts are electrically and mechanically identical. The primary differences are: (1) DME1W5P6K-F is an active product with current manufacturing support, while DME1W5P6K is obsolete; (2) DME1W5P6K-F is ROHS3 compliant, while DME1W5P6K is RoHS non-compliant. Both parts use identical polyester metallized dielectric construction and radial through-hole packaging.

Q: Are there any compatibility concerns with lead spacing or PCB footprint?

A: No. Both parts share identical lead spacing of 0.886" (22.50mm), identical physical dimensions of 1.024" L x 0.354" W (26.00mm x 9.00mm), and identical maximum seated height of 0.689" (17.50mm). PCB footprints designed for either part are fully compatible with the other.

Q: Does the RoHS compliance difference affect electrical performance?

A: No. RoHS compliance relates to material composition and environmental standards, not electrical performance. Both parts deliver identical capacitance, voltage rating, tolerance, and temperature characteristics. The ROHS3 compliance of DME1W5P6K-F reflects improved manufacturing standards without altering circuit behavior.

Q: What is the operating temperature range for both parts?

A: Both DME1W5P6K and DME1W5P6K-F operate across the identical temperature range of -55°C to 125°C, ensuring equivalent thermal performance in all environmental conditions.

Q: Can these parts be used in AC applications?

A: Yes. Both parts carry an AC voltage rating of 65V, in addition to the 100V DC rating. This allows operation in AC circuits up to 65V AC, or in mixed AC/DC applications where the combined stress does not exceed the rated limits.
