Engineering Selection Recommendations

Direct Substitutes (Upgrade Category):

Parts 16MH747MEFC6.3X7, 16ZLG47MEFC6.3X7, and 25ZLG47MEFC6.3X7 are direct substitutes for the 476RSS016M. All three parts maintain identical mechanical dimensions, capacitance value, tolerance, and lead spacing. These Rubycon components are ROHS3 Compliant and REACH Unaffected, meeting regulatory requirements equivalent to the original part.

The 16MH747MEFC6.3X7 and 16ZLG47MEFC6.3X7 maintain the 16 V voltage rating while extending the operating temperature range to 105°C. The 25ZLG47MEFC6.3X7 provides a 25 V voltage rating, suitable for applications where higher voltage margin is required within the same physical footprint.

Similar Part (Voltage Upgrade with Dimensional Variance):

Part MAL203690094E3 is classified as a similar part rather than a direct substitute due to dimensional differences. The case diameter is 0.197" (5.00 mm) versus the required 0.248" (6.30 mm), and the seated height is 0.472" (12.00 mm) versus 0.315" (8.00 mm). This part is suitable only when PCB layout and mechanical clearance accommodate the larger physical dimensions. The 35 V voltage rating and extended lifetime (3000 Hrs @ 85°C) provide enhanced performance characteristics for applications requiring higher voltage ratings.

Compliance Status:

All substitute parts maintain ROHS3 Compliance and REACH Unaffected status, ensuring regulatory compatibility with the original 476RSS016M specification.

Frequently Asked Questions (FAQ)

Q: Can 16MH747MEFC6.3X7 be used as a direct replacement for 476RSS016M?

A: Yes. The 16MH747MEFC6.3X7 maintains identical capacitance (47 µF), voltage rating (16 V), tolerance (±20%), and all mechanical dimensions including lead spacing (0.098"), case diameter (0.248"), and height (0.315"). The part is ROHS3 Compliant and REACH Unaffected. The extended operating temperature range (-40°C to 105°C) and higher lifetime rating at elevated temperature (1000 Hrs @ 105°C) represent performance enhancements.

Q: What is the difference between 16ZLG47MEFC6.3X7 and 25ZLG47MEFC6.3X7?

A: Both parts are Rubycon ZLG series components with identical mechanical dimensions and capacitance (47 µF). The primary difference is voltage rating: 16ZLG47MEFC6.3X7 is rated 16 V, while 25ZLG47MEFC6.3X7 is rated 25 V. Both operate across -40°C to 105°C and provide identical ripple current ratings (86.4 mA @ 120 Hz, 480 mA @ 100 kHz). The 25 V variant is suitable when circuit design requires higher voltage margin.

Q: Why is MAL203690094E3 listed as a similar part rather than a direct substitute?

A: MAL203690094E3 differs in physical dimensions. The case diameter is 0.197" (5.00 mm) compared to the required 0.248" (6.30 mm), and the seated height is 0.472" (12.00 mm) versus 0.315" (8.00 mm). These dimensional differences require PCB layout modification and may affect mechanical clearance. The part is suitable only when design permits accommodation of larger physical dimensions.

Q: Are all substitute parts ROHS3 Compliant?

A: Yes. All substitute parts listed (16MH747MEFC6.3X7, 16ZLG47MEFC6.3X7, 25ZLG47MEFC6.3X7, and MAL203690094E3) are ROHS3 Compliant and REACH Unaffected, maintaining regulatory compatibility with the original 476RSS016M.

Q: What is the significance of the Obsolete product status for Rubycon parts?

A: Obsolete status indicates that 16MH747MEFC6.3X7, 16ZLG47MEFC6.3X7, and 25ZLG47MEFC6.3X7 are no longer in active production. However, inventory availability is documented (4019 Pcs, 3869 Pcs, and 33691 Pcs respectively), indicating current stock availability. Last Time Buy status for MAL203690094E3 indicates limited remaining inventory before discontinuation.

Q: Can 476RSS016M be substituted with a higher voltage-rated part in the same package?

A: Yes, when circuit design permits. The 25ZLG47MEFC6.3X7 (25 V rating) and MAL203690094E3 (35 V rating) maintain the same capacitance and tolerance. However, MAL203690094E3 requires PCB layout modification due to dimensional differences. Higher voltage ratings provide increased safety margin but do not alter the fundamental electrical performance at the original 16 V operating point.

Q: What ripple current specifications should be considered for substitution?

A: The 476RSS016M specifies 80 mA @ 120 Hz and 112 mA @ 100 kHz. Substitute parts 16MH747MEFC6.3X7, 16ZLG47MEFC6.3X7, and 25ZLG47MEFC6.3X7 provide equal or higher ripple current ratings, ensuring compatibility with existing circuit ripple current requirements. MAL203690094E3 provides 130 mA @ 100 Hz, exceeding the original specification.
