SXR102M050AT Equivalent & Substitute Parts

Part Overview

The SXR102M050AT is a 1000 µF, 50 V aluminum electrolytic capacitor in radial, can package manufactured by Cornell Dubilier Electronics (CDE). This component is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. The part operates across a temperature range of -40°C to 105°C and is rated for 5000 hours at 105°C, suitable for general-purpose applications requiring stable capacitance and low equivalent series resistance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SXR102M050AT is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance: 1000 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Voltage Rating: 50 V (exact match required)
• Operating Temperature Range: -40°C ~ 105°C (exact match required)
• Polarization: Polar (exact match required)

Mechanical Parameters:

• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial, Can (exact match required)
• Lead Spacing: 0.295" (7.50mm) (exact match required)
• Size / Dimension: 0.630" Dia (16.00mm) (exact match required)

Compliance Parameters:

• RoHS Status: ROHS3 Compliant (exact match required)

The substitute part EEU-FM1H102 meets all critical electrical and mechanical parameters. Differences in lifetime rating, ESR specifications, and ripple current ratings do not disqualify substitution when the core parameters align.

Parameter Comparison

Engineering Selection Recommendations

The EEU-FM1H102 is a direct electrical and mechanical equivalent to the SXR102M050AT. Both components satisfy identical specifications for capacitance, voltage rating, tolerance, operating temperature range, and physical form factor. The substitute part is manufactured by Panasonic Electronic Components and maintains active product status, ensuring long-term availability and supply chain continuity.

The EEU-FM1H102 offers extended lifetime rating (7000 hours at 105°C versus 5000 hours), which represents an operational advantage over the obsolete SXR102M050AT. Both parts are ROHS3 compliant and suitable for through-hole PCB assembly in general-purpose applications.

The height difference (27.00mm versus 32.00mm) must be evaluated against specific PCB layout constraints. In applications where vertical clearance is limited, the EEU-FM1H102 provides a more compact solution while maintaining all electrical equivalence.

Frequently Asked Questions (FAQ)

Q: Can the EEU-FM1H102 be used as a direct replacement for the SXR102M050AT?

A: Yes. Both components share identical electrical specifications (1000 µF, ±20%, 50 V), operating temperature range (-40°C ~ 105°C), and mechanical form factor (radial, can package, 0.295" lead spacing, 0.630" diameter). PCB layout compatibility is confirmed for standard through-hole assembly.

Q: What is the significance of the height difference between these parts?

A: The SXR102M050AT has a maximum seated height of 1.260" (32.00mm), while the EEU-FM1H102 measures 1.063" (27.00mm). This 5mm difference must be considered during PCB design. In applications with vertical space constraints, the EEU-FM1H102 offers a more compact profile. In applications with existing clearance, both parts are interchangeable.

Q: Are there compliance differences between the main part and substitute?

A: Both parts are ROHS3 compliant. The EEU-FM1H102 carries REACH Unaffected status, providing additional regulatory clarity for European applications.

Q: Why does the EEU-FM1H102 have a longer lifetime rating?

A: The EEU-FM1H102 is rated for 7000 hours at 105°C compared to 5000 hours for the SXR102M050AT. This reflects manufacturing process improvements and material formulations in the Panasonic FM-A series. The extended lifetime does not affect substitution eligibility but represents an operational benefit.

Q: What is the lead spacing tolerance for PCB hole positioning?

A: Both parts specify 0.295" (7.50mm) lead spacing. Standard PCB design practices for through-hole radial capacitors accommodate this spacing without modification.

Q: Is the EEU-FM1H102 available in the same packaging format?

A: The EEU-FM1H102 is supplied in bulk packaging, while the SXR102M050AT was supplied in standard packaging. Both use identical radial, can package format suitable for through-hole assembly. Packaging format does not affect component functionality or substitution compatibility.
