Package configuration: Radial, Can (exact match required)
Mounting type: Through Hole (exact match required)
Polarization: Polar (exact match required)

Acceptable Variation Parameters:

Operating temperature range: substitute must cover or exceed the original range (-40°C to 105°C)
Lifetime rating: substitute may exceed the original 2000-hour specification

Engineering Selection Recommendations

EEU-FC1H101 Selection Criteria:

The EEU-FC1H101 provides direct electrical equivalence to the SH101M050ST with identical 50 V voltage rating and 100 µF capacitance. This substitute maintains the same voltage specification while offering superior reliability through a 3000-hour lifetime rating at 105°C (50% longer than the original). The extended operating temperature range (-55°C to 105°C) provides additional thermal margin. Panasonic's active product status ensures long-term availability and supply chain stability. AEC-Q200 automotive qualification indicates rigorous quality and reliability standards. The increased ripple current capability (399.75 mA @ 120 Hz versus 210 mA) provides design margin for applications with higher current demands.

EEU-FC1J101 Selection Criteria:

The EEU-FC1J101 offers the same 100 µF capacitance with an elevated 63 V voltage rating, providing 26% additional voltage margin over the original 50 V specification. This higher voltage rating accommodates applications with potential voltage transients or future design modifications requiring increased voltage headroom. Like the EEU-FC1H101, this substitute features 3000-hour lifetime rating, extended temperature range, and AEC-Q200 qualification. The 63 V rating introduces minimal physical size increase (0.50 mm additional height) while maintaining identical lead spacing and diameter.

Selection Logic:

Use EEU-FC1H101 for direct replacement in existing designs where 50 V voltage specification is fixed and no additional margin is required
Use EEU-FC1J101 for applications requiring voltage margin, future design flexibility, or environments with potential voltage stress conditions
Both substitutes are mechanically compatible with existing PCB layouts, though height clearance should be verified (12.50 mm maximum versus 12.00 mm original)

Frequently Asked Questions (FAQ)

Q: Can EEU-FC1H101 and EEU-FC1J101 be used interchangeably with SH101M050ST?

A: Both Panasonic substitutes are electrically and mechanically compatible with the SH101M050ST for applications operating at 50 V or below. The EEU-FC1H101 matches the original 50 V rating exactly. The EEU-FC1J101 operates at 63 V and is suitable for any circuit designed for 50 V operation. Selection depends on whether voltage margin is desired.

Q: What is the height difference between the original and substitute parts?

A: The SH101M050ST has a maximum seated height of 12.00 mm. Both Panasonic substitutes (EEU-FC1H101 and EEU-FC1J101) have a maximum seated height of 12.50 mm, representing a 0.50 mm increase. PCB clearance and component placement must accommodate this additional height.

Q: Are the substitute parts RoHS compliant?

A: Yes, both EEU-FC1H101 and EEU-FC1J101 are ROHS3 compliant, matching the compliance status of the original SH101M050ST.

Q: What is the lead spacing for all three parts?

A: All three parts (SH101M050ST, EEU-FC1H101, and EEU-FC1J101) feature identical 5.00 mm lead spacing, ensuring direct PCB footprint compatibility without layout modifications.

Q: Why do the substitute parts have higher ripple current ratings?

A: The Panasonic FC series substitutes feature improved internal construction and lower ESR (Equivalent Series Resistance), resulting in higher ripple current handling capability. The EEU-FC1H101 handles 399.75 mA at 120 Hz compared to the original 210 mA, providing additional design margin for applications with higher AC current stress.

Q: Are the substitute parts suitable for automotive applications?

A: Yes, both Panasonic substitutes carry AEC-Q200 automotive qualification, indicating compliance with automotive reliability and quality standards. The original SH101M050ST does not specify automotive qualification.

Q: What is the difference between EEU-FC1H101 and EEU-FC1J101?

A: The primary difference is voltage rating: EEU-FC1H101 is rated 50 V (matching the original), while EEU-FC1J101 is rated 63 V. Both share identical capacitance (100 µF), tolerance (±20%), lead spacing (5.00 mm), and lifetime rating (3000 hours @ 105°C). The 63 V rating of EEU-FC1J101 provides voltage margin for applications with transient conditions or future design modifications.

Q: Can I use EEU-FC1J101 in a circuit designed for 50 V operation?

A: Yes, the EEU-FC1J101 with 63 V rating is fully compatible with circuits designed for 50 V operation. Higher voltage-rated capacitors operate safely at lower voltages and provide additional safety margin against voltage transients.

Q: What is the inventory status of these substitute parts?

A: EEU-FC1H101 has 80,210 pieces in stock, and EEU-FC1J101 has 98,081 pieces in stock, both from Panasonic Electronic Components. The original SH101M050ST has 848 pieces remaining in inventory.
