• Tolerance: ±10%
• Voltage Rating - DC: 1200V (1.2kV)
• Voltage Rating - AC: 630V
• Dielectric Material: Polypropylene (PP), Metallized
• ESR: 2.7 mOhms
• Operating Temperature Range: -40°C ~ 85°C

Mechanical Parameters (Must Match):

• Mounting Type: Chassis Mount
• Package / Case: Rectangular Box
• Size / Dimension: 1.673" L x 1.319" W (42.50mm x 33.50mm)
• Height - Seated (Max): 1.398" (35.50mm)
• Termination: Screw Terminals

Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected

The substitute parts PMB2124100KSP, PMB2124100KSR, and PMB2124100KVP meet all electrical, mechanical, and compliance requirements and are direct functional equivalents.

Parameter Comparison

Engineering Selection Recommendations

Selection Basis:

All parts maintain identical electrical specifications, mechanical dimensions, and compliance certifications. The PMB2124100KVP offers the highest current inventory availability at 1249 units. The PMB2124100KSP provides 964 units in stock, while the PMB2124100KSR maintains 772 units. All parts are active products with ROHS3 compliance and REACH unaffected status, ensuring regulatory compliance for current and future applications.

Frequently Asked Questions (FAQ)

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

A: Yes. All four part numbers 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 functional substitutes.

Q: Are there any differences in the physical package between these parts?

A: No. All parts share identical mechanical specifications: rectangular box package, 1.673" L x 1.319" W (42.50mm x 33.50mm) footprint, 1.398" (35.50mm) maximum seated height, and screw terminal termination. They are mechanically interchangeable.

Q: Do all substitute parts meet the same compliance requirements?

A: Yes. All parts are ROHS3 compliant and REACH unaffected, meeting current regulatory standards for electronic components.

Q: What is the difference between the part number suffixes (VR, SP, SR, VP)?

A: The suffixes indicate internal Nichicon manufacturing or packaging variations within the PMB series. All variants maintain identical electrical and mechanical specifications for the 1 µF, 1200V DC film capacitor configuration.

Q: Which substitute part should be selected based on availability?

A: Selection should be based on inventory requirements and supply chain considerations. PMB2124100KVP has the highest inventory (1249 units), followed by PMB2124100KSP (964 units) and PMB2124100KSR (772 units). The original PMB2124100KVR maintains 821 units in stock.

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

A: Yes. All parts are rated for high-frequency switching, high-pulse DV/DT environments, and snubber circuit applications as specified in the product documentation.
