Engineering Selection Recommendations

The PB-5R0V474-R is the direct substitute for the obsolete PB-5R0V474. Selection of the substitute part is based on the following factors:

Product Status: The PB-5R0V474 is obsolete. The PB-5R0V474-R maintains active product status, ensuring long-term availability and manufacturing support.

Regulatory Compliance: The substitute part is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. The original part is RoHS non-compliant.

Electrical Equivalence: All electrical parameters—capacitance, voltage rating, ESR, and thermal lifetime—are identical between the two parts.

Mechanical Compatibility: Physical dimensions, lead spacing, and mounting configuration are identical, enabling direct board-level substitution without PCB redesign.

Inventory Availability: The substitute part has significantly higher inventory availability (5439 pcs vs. 1190 pcs), supporting production continuity.

Frequently Asked Questions (FAQ)

Q: Can PB-5R0V474-R be used as a direct replacement for PB-5R0V474 on existing PCBs?

A: Yes. All electrical and mechanical parameters are identical. The parts are pin-compatible and dimensionally equivalent. No PCB modifications are required.

Q: What is the difference between these two part numbers?

A: The primary differences are product status (obsolete vs. active), packaging format (standard vs. bulk), and compliance certifications (RoHS non-compliant vs. ROHS3 compliant). Electrical and mechanical specifications are identical.

Q: Are there any performance differences between PB-5R0V474 and PB-5R0V474-R?

A: No. Both parts have identical capacitance (470 mF), voltage rating (5 V), ESR (1 Ohm @ 100Hz), thermal lifetime (1000 Hrs @ 70°C), and operating temperature range (-25°C to 70°C).

Q: Does the bulk packaging of PB-5R0V474-R affect component quality?

A: Packaging format does not affect electrical or mechanical performance. Bulk packaging is a distribution method and does not impact component specifications or reliability.

Q: Is PB-5R0V474-R suitable for new designs?

A: Yes. The active product status and ROHS3 compliance make PB-5R0V474-R the appropriate choice for new designs. The obsolete PB-5R0V474 should not be used in new applications.

Q: What is the lead spacing tolerance for these supercapacitors?

A: Lead spacing is 0.465" (11.80mm) for both parts. This dimension is fixed and applies to through-hole radial can packaging.

Q: Can these parts be used in high-temperature applications?

A: The operating temperature range is -25°C to 70°C for both parts. The rated lifetime is 1000 hours at 70°C. Applications requiring operation above 70°C require alternative components with higher temperature ratings.
