Substitute Part Grouping Explanation

Substitute parts for the DPM6S1K-F are identified based on strict electrical and mechanical parameter matching. The substitution logic is based on the following criteria:

Electrical Parameters (Non-Negotiable):

• Capacitance value: 10000 pF
• DC voltage rating: 630V minimum
• AC voltage rating: 250V minimum
• Tolerance: ±10% or tighter
• Dielectric: Polypropylene metallized film
• Temperature range: -55°C to +105°C minimum

Mechanical Parameters (Non-Negotiable):

• Mounting: Through-hole radial configuration
• Lead spacing: 0.394" (10.00 mm)
• Termination: PC pins

Compliance Parameters:

• RoHS3 compliance required
• MSL rating: 1 (Unlimited)

The 103MPR630K from Cornell Dubilier / Illinois Capacitor meets all critical electrical and mechanical parameters. Physical dimensions vary within acceptable tolerances for through-hole radial mounting, with the substitute featuring a more compact height profile (0.394" vs. 0.551" seated height).

Engineering Selection Recommendations

Primary Part: DPM6S1K-F

The DPM6S1K-F remains the primary selection when available. This part is actively manufactured by Cornell Dubilier Electronics with 679 units in current inventory. Full RoHS3 compliance and MSL 1 rating support deployment in standard manufacturing environments without moisture control requirements.

Substitute Part: 103MPR630K

The 103MPR630K is a direct electrical and mechanical equivalent suitable for applications where the DPM6S1K-F is unavailable. This part is supplied by Cornell Dubilier / Illinois Capacitor with 2916 units in inventory, providing enhanced supply availability. The substitute maintains identical electrical specifications and compliance certifications. The more compact physical dimensions (0.394" height vs. 0.551", 0.236" width vs. 0.276") represent a design improvement that reduces PCB footprint while maintaining full electrical performance. Both parts share identical lead spacing (0.394" / 10.00 mm), ensuring direct PCB footprint compatibility.

Selection Criteria:

• Use DPM6S1K-F when inventory availability and original part specification are priorities
• Use 103MPR630K when supply chain continuity, enhanced inventory levels, or compact form factor benefits are required
• Both parts are suitable for DC link, DC filtering, and high-frequency switching applications
• Both parts meet all regulatory and compliance requirements for standard industrial and commercial applications

Frequently Asked Questions (FAQ)

Q: Can the 103MPR630K be used as a direct replacement for the DPM6S1K-F on existing PCBs?

A: Yes. The 103MPR630K is electrically and mechanically compatible. Both parts have identical lead spacing (0.394" / 10.00 mm), identical voltage ratings (630V DC / 250V AC), identical capacitance (10000 pF), and identical tolerance (±10%). The substitute features a more compact physical profile but occupies the same PCB footprint.

Q: What are the key electrical parameters that must match for substitution?

A: Capacitance (10000 pF), DC voltage rating (630V), AC voltage rating (250V), tolerance (±10%), dielectric material (polypropylene metallized), and operating temperature range (-55°C to +105°C) must all match exactly. These parameters determine circuit performance and reliability.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both the DPM6S1K-F and 103MPR630K are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited moisture sensitivity) ratings. Both are classified as Active products with identical regulatory status.

Q: Why does the 103MPR630K have different physical dimensions?

A: The 103MPR630K represents a more compact design iteration within the same electrical specification class. The reduced height (0.394" vs. 0.551") and width (0.236" vs. 0.276") provide PCB layout benefits without compromising electrical performance or reliability. Lead spacing remains identical at 0.394" (10.00 mm).

Q: Which part should be selected for new designs?

A: For new designs, either part is acceptable based on availability and supply chain strategy. The 103MPR630K offers higher inventory availability (2916 units vs. 679 units) and a more compact form factor. The DPM6S1K-F is the original specification. Consult with your procurement and supply chain team to determine the optimal selection based on lead times and inventory positioning.

Q: Are these parts suitable for high-frequency switching applications?

A: Yes. Both parts are specified for high-frequency switching and DC filtering applications. Both feature low ESR and low ESL characteristics (DPM6S1K-F explicitly lists both; 103MPR630K lists low ESR). Polypropylene metallized dielectric construction supports these performance requirements.

Q: What is the lead spacing and how does it affect PCB compatibility?

A: Both parts have identical lead spacing of 0.394" (10.00 mm). This measurement determines PCB footprint compatibility. Identical lead spacing ensures that either part can be mounted on the same PCB without modification.
