Parameter Comparison

Engineering Selection Recommendations

Both parts maintain Active product status and are manufactured by Vishay Sprague within the 30D series. The primary distinction between the main part and substitute is RoHS compliance status: 30D477M025DF2AE3 is RoHS3 compliant, while 30D477M025DF2A is RoHS non-compliant.

Selection between these parts depends on regulatory and procurement requirements. Applications subject to RoHS3 mandates must use 30D477M025DF2AE3. Applications without RoHS compliance requirements may use either part based on availability and supply chain considerations. The substitute part currently maintains higher inventory availability at 1395 pieces compared to 767 pieces for the main part.

Frequently Asked Questions (FAQ)

Q: Can 30D477M025DF2A directly replace 30D477M025DF2AE3 in all applications?

A: Direct electrical and mechanical replacement is possible due to identical capacitance, voltage rating, tolerance, ESR, thermal lifetime, operating temperature range, ripple current specifications, and physical dimensions. However, RoHS compliance status differs. Applications requiring RoHS3 compliance must use 30D477M025DF2AE3.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts share identical axial, can package dimensions of 0.374" diameter by 1.260" length (9.50mm x 32.00mm), confirming through-hole mounting compatibility on equivalent PCB layouts.

Q: What is the significance of the RoHS compliance difference?

A: RoHS3 compliance indicates adherence to Restriction of Hazardous Substances regulations. The main part (30D477M025DF2AE3) meets this requirement; the substitute does not. Selection depends on end-product regulatory obligations and market destination requirements.

Q: Do these parts have identical electrical performance?

A: Yes. Both parts specify 470 µF capacitance, 25 V rated voltage, ±20% tolerance, 612 mOhm ESR @ 120Hz, 2000 hour lifetime @ 105°C, and identical ripple current ratings at both 120 Hz and 100 kHz frequencies.

Q: Which part should be selected for new designs?

A: Selection is based on regulatory compliance requirements and supply chain availability. For RoHS3-regulated applications, use 30D477M025DF2AE3. For applications without RoHS mandates, either part is electrically and mechanically equivalent.
