Substitute Part Grouping Explanation

Substitution of the SH471M050ST is determined by strict equivalence across the following parameters: capacitance value (470 µF), voltage rating (50 V), tolerance (±20%), polarization (polar), package type (radial can), mounting type (through hole), and lead spacing (5.00 mm). All substitute parts must maintain these core electrical and mechanical specifications to ensure direct compatibility in circuit applications.

The substitute parts are grouped into two categories:

Upgrade Substitutes provide enhanced performance characteristics while maintaining full electrical and mechanical compatibility. These parts offer extended lifetime ratings, improved ripple current handling, or lower impedance specifications compared to the original SH471M050ST.

Similar Substitutes maintain equivalent core specifications but may differ in secondary performance parameters such as ripple current capacity or impedance. These parts are suitable for applications where the original performance envelope is sufficient.

Engineering Selection Recommendations

For Active Production and New Designs:

EEU-EB1H471 (Panasonic) is the primary recommended substitute. This part carries active product status and provides a 5× improvement in lifetime rating (10000 hours versus 2000 hours at 105°C). It maintains full electrical and mechanical compatibility with the SH471M050ST while offering enhanced reliability for long-term applications. ROHS3 compliance and REACH unaffected status confirm regulatory alignment.

EKZE500ELL471MK20S (Chemi-Con) serves as a secondary active substitute with a 2.5× lifetime improvement (5000 hours). This part offers superior ripple current handling at both low and high frequencies compared to the original specification, making it suitable for applications with elevated AC stress requirements.

For Legacy System Support:

ECA-1HHG471 (Panasonic) maintains the original 2000-hour lifetime specification and carries active product status. This part is suitable for direct replacement in existing designs where performance envelope requirements match the original SH471M050ST. The smaller diameter (10.00 mm versus 13.00 mm) requires verification of available board space.

Parts Not Recommended for New Designs:

UHE1H471MHD6, UPS1H471MHD, and UPW1H471MHD carry "Not For New Designs" status and should be used only for legacy system maintenance or repair applications where original part sourcing is unavailable.

Frequently Asked Questions (FAQ)

Q: Can EEU-EB1H471 be used as a direct replacement for SH471M050ST in existing circuit boards?

A: Yes. EEU-EB1H471 maintains identical capacitance (470 µF), voltage rating (50 V), tolerance (±20%), lead spacing (5.00 mm), and through-hole mounting configuration. The physical dimensions differ slightly (height 22.00 mm versus 20.00 mm and diameter 12.50 mm versus 13.00 mm), requiring verification that the component fits within available board space and clearance constraints.

Q: What is the primary advantage of EKZE500ELL471MK20S over the original SH471M050ST?

A: EKZE500ELL471MK20S provides significantly higher ripple current capacity at both low frequency (1.025 A @ 120 Hz versus 730 mA) and high frequency (2.05 A @ 100 kHz versus 1.022 A). This enhanced current handling capability makes it suitable for applications with elevated AC stress. The part also offers a 2.5× improvement in lifetime rating (5000 hours versus 2000 hours at 105°C).

Q: Why do some substitute parts show "Not For New Designs" status?

A: Parts designated "Not For New Designs" (UHE1H471MHD6, UPS1H471MHD, UPW1H471MHD) are maintained in inventory for legacy system support and repair applications only. Manufacturers restrict their use in new product development to encourage migration to active, current-generation alternatives with improved performance and extended support lifecycles.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed maintain ROHS3 compliance, ensuring regulatory alignment with current environmental and hazardous substance restrictions.

Q: Does the smaller diameter of ECA-1HHG471 affect electrical performance?

A: No. The diameter reduction (10.00 mm versus 13.00 mm) is a physical packaging difference that does not alter electrical specifications. Capacitance, voltage rating, tolerance, and operating characteristics remain equivalent. Physical fit verification on the target circuit board is required.

Q: Which substitute part offers the longest operational lifetime?

A: EEU-EB1H471 and UHE1H471MHD6 both provide 10000-hour lifetime ratings at 105°C, representing a 5× improvement over the original SH471M050ST (2000 hours). EEU-EB1H471 is recommended for new designs due to its active product status.
