Engineering Selection Recommendations

The KR-5R5H474-R supercapacitor from Eaton - Electronics Division is a functional substitute for the obsolete EDLSG474H5R5C. Both components maintain identical electrical specifications for capacitance (470 mF), rated voltage (5.5 V), operating temperature range (-25°C to 70°C), and lifetime rating (1000 hours at 70°C).

The KR-5R5H474-R is currently in active production status with substantial inventory availability (12,733 pieces), whereas the EDLSG474H5R5C is obsolete. Both parts are ROHS3 compliant and carry identical ECCN and HTSUS classifications.

Physical dimensions and lead spacing differ between the two parts. The KR-5R5H474-R features a smaller diameter (0.453" versus 0.787"), reduced height (0.197" versus 0.256"), and different lead spacing (0.394" versus 0.787"). PCB layout modifications are required to accommodate the KR-5R5H474-R.

The KR-5R5H474-R exhibits higher equivalent series resistance (50 Ohm @ 1 kHz versus 30 Ohm @ 1 kHz). Applications sensitive to ESR performance characteristics must evaluate this parameter against specific circuit requirements.

Frequently Asked Questions (FAQ)

Q: Can the KR-5R5H474-R directly replace the EDLSG474H5R5C without PCB modifications?

A: No. While both parts are functionally equivalent supercapacitors with identical electrical ratings, they have different physical dimensions and lead spacing. The KR-5R5H474-R is smaller (0.453" diameter versus 0.787" diameter) with different lead spacing (0.394" versus 0.787"). PCB layout modifications are required for mechanical compatibility.

Q: What is the significance of the ESR difference between these parts?

A: The KR-5R5H474-R has an ESR of 50 Ohm @ 1 kHz compared to 30 Ohm @ 1 kHz for the EDLSG474H5R5C. ESR affects charging/discharging rates and heat generation. Applications with strict ESR requirements must evaluate whether the higher ESR of the substitute part is acceptable for the intended circuit function.

Q: Are both parts RoHS compliant?

A: Yes. Both the EDLSG474H5R5C and KR-5R5H474-R are ROHS3 compliant and carry identical ECCN (EAR99) and HTSUS (8532.29.0040) classifications.

Q: What is the product status difference between these parts?

A: The EDLSG474H5R5C is classified as obsolete, indicating it is no longer manufactured. The KR-5R5H474-R is in active production status with current inventory availability, making it suitable for new designs and ongoing production requirements.

Q: Do both parts have the same operating temperature range?

A: Yes. Both the EDLSG474H5R5C and KR-5R5H474-R operate across the identical temperature range of -25°C to 70°C with a lifetime specification of 1000 hours at 70°C.

Q: What mounting configuration do these supercapacitors use?

A: Both parts are through-hole mounted components with axial, can-horizontal package configuration and PC pin termination. They are designed for insertion into PCB holes with subsequent soldering.
