Frequently Asked Questions (FAQ)

Q: Can PMB2124100KSR, PMB2124100KVP, and PMB2124100KVR be used interchangeably with PMB2124100KSP?

A: Yes. All four parts are parametric equivalents with identical capacitance (1 µF), voltage ratings (1200V DC / 630V AC), tolerance (±10%), dielectric material (polypropylene metallized), ESR (2.7 mOhms), operating temperature range (-40°C ~ 85°C), and mechanical dimensions. They are direct substitutes for applications requiring 1 µF film capacitors with 1.2kV DC rating.

Q: What is the difference between these substitute parts?

A: The substitute parts differ only in their internal construction or manufacturing process, which does not affect electrical performance or mechanical compatibility. All parts share identical external dimensions, termination type (screw terminals), and performance characteristics.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. PMB2124100KSP, PMB2124100KSR, PMB2124100KVP, and PMB2124100KVR are all ROHS3 compliant and REACH unaffected, meeting environmental and regulatory standards for industrial applications.

Q: Do these parts have the same physical footprint?

A: Yes. All parts share identical dimensions: 1.673" L x 1.319" W (42.50mm x 33.50mm) with a maximum seated height of 1.398" (35.50mm). They are housed in rectangular box packages with screw terminals and are suitable for chassis mount applications.

Q: Which substitute part should I select based on availability?

A: Selection depends on current inventory levels. PMB2124100KVP has the highest inventory at 1249 pieces, making it the optimal choice for immediate availability. PMB2124100KSP, PMB2124100KVR, and PMB2124100KSR are available in descending order of stock quantity.

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

A: Yes. All parts are rated for high frequency switching, high pulse DV/DT, and snubber applications. The 2.7 mOhms ESR specification supports these demanding circuit requirements.

Q: What is the operating temperature range for these capacitors?

A: All substitute parts operate within the range of -40°C to 85°C, ensuring performance across industrial and commercial temperature environments.
