SXR151M100ST Equivalent & Substitute Parts

Part Overview

The SXR151M100ST is a 150 µF, 100 V aluminum electrolytic capacitor in radial, can package manufactured by Cornell Dubilier Electronics (CDE). This component is classified as obsolete, making direct replacement necessary for ongoing production and maintenance applications. The part operates across a temperature range of -40°C to 105°C and is rated for general-purpose applications requiring 4000 hours of lifetime at 105°C. Equivalent and substitute parts are available from active manufacturers including Rubycon, Panasonic Electronic Components, and Nichicon, offering improved performance characteristics and extended product availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SXR151M100ST is determined by strict equivalence across the following parameters:

Critical Matching Parameters:

• Capacitance: 150 µF (exact match required)
• Voltage Rating: 100 V (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)
• Package Type: Radial, Can (exact match required)
• Mounting Type: Through Hole (exact match required)
• Lead Spacing: 0.197" (5.00mm) (exact match required)
• Operating Temperature Range: -40°C ~ 105°C minimum (exact match or extended range acceptable)

Performance Parameters (Allowed Variation):

• Lifetime @ 105°C: Substitute parts may exceed the original 4000 hours specification
• ESR (Equivalent Series Resistance): Lower values indicate improved performance
• Ripple Current: Higher values indicate improved performance
• Physical Dimensions: Slight variations in diameter and height are acceptable provided lead spacing remains constant

All substitute parts listed meet or exceed the critical matching parameters. Substitute parts from Rubycon (100ZLH150MEFC12.5X20, 100ZLJ150M12.5X20) and Panasonic (EEU-FS2A151) are classified as Active products with extended lifetime ratings of 10000 hours at 105°C. The Nichicon UPW2A151MHD is classified as Not For New Designs but remains functionally compatible with a 7000-hour lifetime rating.

Parameter Comparison

Engineering Selection Recommendations

For New Designs and Production:

The Rubycon 100ZLH150MEFC12.5X20 and 100ZLJ150M12.5X20, and Panasonic EEU-FS2A151 are recommended as primary substitutes. All three parts are classified as Active products with ROHS3 compliance and extended lifetime ratings of 10000 hours at 105°C, providing superior reliability compared to the obsolete SXR151M100ST. These parts are electrically and mechanically compatible with the original specification and are suitable for new design implementations.

For Maintenance and Legacy Systems:

The Nichicon UPW2A151MHD is functionally compatible and provides adequate performance for replacement applications in existing systems. Although classified as Not For New Designs, this part meets all critical electrical and mechanical parameters and offers extended temperature range capability (-55°C to 105°C). Selection of this part should be limited to field replacement and maintenance scenarios where design revision is not feasible.

Physical Dimension Considerations:

All substitute parts feature reduced height (22.00mm or 25.00mm) compared to the original SXR151M100ST (30.00mm). Diameter increases from 12.00mm to 12.50mm are within acceptable tolerance for radial can packages. PCB layout verification is required to confirm adequate clearance in confined spaces, particularly for the original 30.00mm height specification.

Frequently Asked Questions (FAQ)

Q: Can the SXR151M100ST be directly replaced with any of the listed substitute parts?

A: Yes. All listed substitute parts meet the critical electrical parameters (150 µF, 100 V, ±20% tolerance) and mechanical specifications (radial can package, 5.00mm lead spacing, through-hole mounting). Physical dimensions vary slightly; verification of PCB clearance is required before installation.

Q: What is the primary advantage of using Rubycon or Panasonic substitutes over the Nichicon UPW2A151MHD?

A: Rubycon and Panasonic parts are classified as Active products with 10000-hour lifetime ratings at 105°C, compared to 7000 hours for the Nichicon part. Active product status ensures continued availability and manufacturing support. The Nichicon part is classified as Not For New Designs and should be reserved for maintenance applications only.

Q: Are there any compatibility issues with PCB mounting?

A: The substitute parts feature identical lead spacing (5.00mm) and through-hole mounting type, ensuring direct PCB compatibility. However, substitute parts are shorter (22.00mm or 25.00mm height) than the original (30.00mm height). Verify adequate clearance above the capacitor in confined spaces. Diameter increases from 12.00mm to 12.50mm are negligible for standard PCB layouts.

Q: Do all substitute parts meet RoHS compliance requirements?

A: Yes. All substitute parts are ROHS3 compliant, matching the compliance status of the original SXR151M100ST. No additional environmental or regulatory considerations apply to substitution.

Q: Which substitute part offers the best electrical performance?

A: The Panasonic EEU-FS2A151 provides the lowest impedance (43 mOhms) and highest ripple current capability at 100 kHz (1.4 A), indicating superior high-frequency performance. The Rubycon 100ZLJ150M12.5X20 offers the second-best performance with 62 mOhms impedance and 1.75 A ripple current at 100 kHz. Selection should be based on specific application requirements for ripple current handling and ESR sensitivity.

Q: Is the extended operating temperature range of the Nichicon UPW2A151MHD (-55°C to 105°C) beneficial for my application?

A: The extended lower temperature limit (-55°C versus -40°C) is beneficial only if your application requires operation below -40°C. For standard applications operating within -40°C to 105°C, this feature provides no functional advantage. Rubycon and Panasonic parts meet the standard temperature range requirement.
