Substitute Part Grouping Explanation

Substitution of the 475HSM050M is determined by the following critical parameters: capacitance value (4.7 µF), voltage rating (50 V minimum), tolerance (±20%), polarization (polar), package configuration (radial, can), mounting type (through hole), and lead spacing (0.138" / 3.50 mm). Parts are grouped into three categories based on substitution compatibility:

Direct Equivalent (Same Voltage Rating): Parts maintaining 50 V voltage rating with identical capacitance, tolerance, and physical footprint. These provide one-to-one replacement capability.

Upgrade Substitutes (Higher Voltage Rating): Parts rated at 100 V or higher voltage with matching capacitance and tolerance. These provide enhanced voltage margin and are physically compatible with the original mounting footprint, though some dimensional variations exist in height.

Similar Alternative (Different Voltage/Specifications): Parts with matching capacitance and tolerance but differing voltage ratings, physical dimensions, or lead spacing. These require circuit evaluation for suitability.

Engineering Selection Recommendations

Direct Equivalent Selection:

UBT1H4R7MPD8 (Nichicon) provides direct electrical equivalence to the 475HSM050M with identical capacitance, voltage rating, and tolerance. This part is active in production and ROHS3 compliant. The height difference of 0.019" (0.50 mm) is within typical PCB layout tolerances for through-hole components. This part is suitable for direct replacement in applications where the original specifications are required.

Upgrade Substitute Selection:

The Rubycon RX30 series parts (50RX304.7M8X11.5, 50RX304R7M8X11.5, 100RX304.7M8X11.5, 100RX304R7M8X11.5) and Chemi-Con EGXE101ELL4R7MH12D offer enhanced performance characteristics. The 50 V rated parts (50RX304.7M8X11.5 and 50RX304R7M8X11.5) maintain voltage equivalence while providing improved thermal performance (2000 Hrs @ 130°C versus 2000 Hrs @ 125°C) and AEC-Q200 automotive qualification. The 100 V rated parts provide voltage margin for applications requiring enhanced reliability. All RX30 series parts are ROHS3 compliant and AEC-Q200 qualified.

Similar Alternative Selection:

200LEX4.7MEFC6.3X11 (Rubycon LEX series) differs in lead spacing (0.098" versus 0.138") and voltage rating (200 V), requiring PCB layout verification. This part offers extended lifetime (4000 Hrs @ 125°C) and is suitable only when circuit design accommodates the different lead spacing and higher voltage rating provides system benefit.

Frequently Asked Questions (FAQ)

Q: Can UBT1H4R7MPD8 directly replace 475HSM050M without PCB modification?

A: Yes. UBT1H4R7MPD8 maintains identical lead spacing (0.138" / 3.50 mm), capacitance (4.7 µF), voltage rating (50 V), and tolerance (±20%). The height difference of 0.019" (0.50 mm) is within standard through-hole component tolerances and does not require PCB layout changes.

Q: What is the advantage of using 50RX304.7M8X11.5 over the direct equivalent?

A: 50RX304.7M8X11.5 provides improved thermal performance with rated lifetime of 2000 Hrs @ 130°C compared to the original 2000 Hrs @ 125°C. It carries AEC-Q200 automotive qualification and ROHS3 compliance. Physical compatibility is maintained with identical lead spacing and voltage rating.

Q: Are the 100 V rated parts (100RX304.7M8X11.5, 100RX304R7M8X11.5, EGXE101ELL4R7MH12D) suitable for 50 V applications?

A: Yes. Higher voltage-rated capacitors are electrically compatible with lower voltage applications. The 100 V rating provides additional voltage margin and is suitable for circuits designed for 50 V operation. Circuit design must accommodate any dimensional differences in height.

Q: Why does 200LEX4.7MEFC6.3X11 have different lead spacing?

A: 200LEX4.7MEFC6.3X11 is from the LEX series with 0.098" (2.50 mm) lead spacing, compared to 0.138" (3.50 mm) for the original part. This part requires PCB layout verification and is not a direct footprint replacement.

Q: What compliance certifications are relevant for automotive applications?

A: Rubycon RX30 series parts (50RX304.7M8X11.5, 50RX304R7M8X11.5, 100RX304.7M8X11.5, 100RX304R7M8X11.5) and Chemi-Con EGXE101ELL4R7MH12D carry AEC-Q200 qualification, suitable for automotive applications. All active substitute parts are ROHS3 compliant.

Q: Is the original 475HSM050M still available?

A: No. The 475HSM050M is classified as obsolete. Active equivalent and substitute parts must be selected from the provided alternatives for new designs and production continuity.
