Parameter Comparison

Engineering Selection Recommendations

Both PSB2103470KJS and PSB2103470KJL are active production parts from Nichicon with identical electrical and mechanical specifications. Selection between these parts is based on availability and inventory status:

PSB2103470KJS is the primary part number with 1074 units currently in stock.

PSB2103470KJL is a direct parametric equivalent with 1068 units currently in stock, suitable for use when PSB2103470KJS inventory is constrained.

Both parts are ROHS3 compliant and suitable for high-frequency switching, high-pulse, and snubber applications within the specified operating temperature range of -40°C to 85°C. The identical electrical characteristics (0.47 µF capacitance, 1000V DC rating, 4.7 mOhms ESR) and mechanical dimensions (radial package, 37.50mm lead spacing) ensure direct functional interchangeability in circuit designs.

Frequently Asked Questions (FAQ)

Q: Can PSB2103470KJL be used as a direct replacement for PSB2103470KJS?

A: Yes. PSB2103470KJL meets all electrical and mechanical parameter requirements identical to PSB2103470KJS. Both parts share the same capacitance (0.47 µF), voltage rating (1000V DC), tolerance (±10%), dielectric material (polypropylene metallized), ESR (4.7 mOhms), operating temperature range (-40°C to 85°C), and physical dimensions (radial package, 42.50mm x 30.00mm, 37.50mm lead spacing).

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

A: Both PSB2103470KJS and PSB2103470KJL are ROHS3 compliant. Both are active production parts from Nichicon with identical regulatory status.

Q: What applications are these capacitors suitable for?

A: These 0.47 µF film capacitors are designed for high-frequency switching applications, high-pulse environments with significant dV/dT characteristics, and snubber circuits. The 1000V DC rating and polypropylene dielectric provide stability across the -40°C to 85°C operating temperature range.

Q: Are the physical dimensions identical between PSB2103470KJS and PSB2103470KJL?

A: Yes. Both parts have identical dimensions: 1.673" L x 1.181" W (42.50mm x 30.00mm), maximum seated height of 1.772" (45.00mm), and lead spacing of 1.476" (37.50mm). Both use radial through-hole mounting with PC pin termination.

Q: What is the ESR specification and why is it important?

A: Both parts have an ESR (Equivalent Series Resistance) of 4.7 mOhms. ESR is critical in high-frequency and high-pulse applications as it affects energy dissipation, ripple current handling, and overall circuit performance. The identical ESR specification ensures equivalent performance in these demanding applications.

Q: Can these capacitors be used in AC applications?

A: Yes. Both parts are rated for 575V AC in addition to the 1000V DC rating. The AC rating applies to sinusoidal voltage conditions and is relevant for AC filtering and coupling applications.
