Engineering Selection Recommendations

SEK4R7M063ST (CDE) - Primary Direct Equivalent

The SEK4R7M063ST is the recommended primary substitute for the SH4R7M063ST. This part maintains identical capacitance (4.7 µF) and voltage rating (63 V) with equivalent ESR characteristics (28.23 Ohm @ 120 Hz). The SEK series is in active production status, ensuring supply availability. Operating temperature range extends to -55°C, providing enhanced low-temperature performance. Mechanical dimensions are compatible with identical lead spacing (2.00 mm) and diameter (5.00 mm), though seated height increases from 11.00 mm to 13.00 mm. This height difference requires verification against PCB layout constraints. RoHS3 compliance and REACH unaffected status confirm regulatory alignment.

EEU-EB1J4R7S (Panasonic) - Extended Lifetime Alternative

The EEU-EB1J4R7S provides a 63 V rated alternative with extended operational lifetime of 5000 hours at 105°C, compared to 2000 hours for the original part. Manufactured by Panasonic, this component maintains identical capacitance and voltage specifications with compatible mechanical dimensions. Seated height of 12.00 mm falls between the original and SEK alternatives. Lower ripple current ratings (23 mA @ 120 Hz, 37.95 mA @ 100 kHz) indicate reduced thermal stress capability. This part is suitable for applications where extended service life is prioritized and ripple current demands are within specified limits. RoHS3 compliance and REACH unaffected status are confirmed.

SEK4R7M100ST (CDE) - Voltage Upgrade Option

The SEK4R7M100ST offers a 100 V voltage rating while maintaining 4.7 µF capacitance and ±20% tolerance. This elevated voltage rating provides additional design margin in circuits where voltage stress is a concern. Electrical characteristics remain equivalent (28.23 Ohm ESR), with identical lead spacing and diameter. Seated height of 13.00 mm requires PCB layout verification. Active production status ensures availability. This substitute is applicable only when circuit design permits the higher voltage rating without adverse effects on circuit performance or cost considerations.

UPW2A4R7MDD (Nichicon) - Voltage Upgrade with Enhanced Ripple Current

The UPW2A4R7MDD is a 100 V rated alternative manufactured by Nichicon with 4.7 µF capacitance. This part exhibits higher ripple current capability at high frequency (74 mA @ 100 kHz) compared to the original specification. Seated height of 11.00 mm matches the original part, simplifying PCB layout compatibility. However, this part is classified as obsolete, limiting long-term supply reliability. Selection of this substitute is not recommended for new designs or applications requiring sustained component availability.

Frequently Asked Questions (FAQ)

Q1: Can the SEK4R7M063ST be used as a direct replacement for the SH4R7M063ST?

A: Yes. The SEK4R7M063ST is electrically and mechanically compatible with the SH4R7M063ST. Both parts share identical capacitance (4.7 µF), voltage rating (63 V), tolerance (±20%), and lead spacing (2.00 mm). The primary difference is seated height: SEK4R7M063ST measures 13.00 mm versus 11.00 mm for the original. Verify PCB layout clearance before implementation. The SEK series is in active production, providing superior supply availability compared to the obsolete SH series.

Q2: What is the significance of the voltage rating difference between 63 V and 100 V substitutes?

A: Voltage rating indicates the maximum continuous voltage the capacitor can withstand without degradation. A 100 V rated capacitor (SEK4R7M100ST, UPW2A4R7MDD) can be used in circuits designed for 63 V operation, providing additional voltage margin. However, 100 V rated capacitors typically exhibit larger physical dimensions or different electrical characteristics. Use 100 V substitutes only when circuit design permits and when supply constraints for 63 V alternatives are prohibitive.

Q3: Why does the EEU-EB1J4R7S have a longer lifetime specification (5000 hours vs. 2000 hours)?

A: Lifetime specification reflects the expected operational duration at maximum rated temperature (105°C) before capacitance degradation exceeds tolerance limits. The EEU-EB1J4R7S achieves 5000 hours through superior internal construction and materials. This extended lifetime reduces replacement frequency in applications with continuous operation at elevated temperatures. Selection depends on application duty cycle and maintenance accessibility.

Q4: Are there mechanical compatibility issues when substituting parts with different seated heights?

A: Yes. Seated height differences affect PCB layout, component clearance, and assembly processes. The SH4R7M063ST measures 11.00 mm, while SEK4R7M063ST measures 13.00 mm and EEU-EB1J4R7S measures 12.00 mm. Verify that increased height does not interfere with adjacent components, enclosure constraints, or automated assembly equipment. If height is critical, the UPW2A4R7MDD (11.00 mm) maintains original dimensions, though it is obsolete.

Q5: What does "obsolete" product status mean for component selection?

A: Obsolete status indicates the manufacturer has discontinued production. The SH4R7M063ST and UPW2A4R7MDD are obsolete, meaning existing inventory is finite and replenishment is unavailable. For new designs or long-term applications, select active production alternatives such as SEK4R7M063ST, SEK4R7M100ST, or EEU-EB1J4R7S to ensure sustained supply chain reliability.

Q6: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts (SEK4R7M063ST, SEK4R7M100ST, EEU-EB1J4R7S, UPW2A4R7MDD) are RoHS3 compliant, matching the original SH4R7M063ST. RoHS3 compliance confirms absence of restricted substances (lead, cadmium, mercury, hexavalent chromium, polybrominated biphenyls, polybrominated diphenyl ethers) in concentrations exceeding specified limits.

Q7: How do ripple current ratings affect component selection?

A: Ripple current rating indicates the maximum AC current the capacitor can handle without exceeding temperature limits. The SH4R7M063ST specifies 34 mA @ 120 Hz and 47.6 mA @ 10 kHz. Substitute parts exhibit varying ripple current capabilities. The EEU-EB1J4R7S shows lower ripple current (23 mA @ 120 Hz), while UPW2A4R7MDD shows higher ripple current (74 mA @ 100 kHz). Select substitutes with ripple current ratings equal to or exceeding circuit requirements to prevent thermal stress and premature failure.

Q8: What is the importance of lead spacing and diameter specifications?

A: Lead spacing (0.079" / 2.00 mm) and diameter (0.197" / 5.00 mm) determine PCB footprint compatibility. All listed substitutes maintain identical lead spacing and diameter, ensuring direct PCB mounting compatibility without layout redesign. These mechanical parameters are critical for automated assembly processes and component placement accuracy.
