T54EE157M030ESS075 Equivalent & Substitute Parts

Part Overview

The T54EE157M030ESS075 is a 150 µF molded tantalum polymer capacitor rated at 30 V, manufactured by Vishay Polytech as part of the vPolyTan™ T54 series. This component is currently in active production status and is designed for surface mount applications in the 2917 (7343 Metric) package format. The capacitor features an ESR of 75 mOhm @ 100 kHz and operates across a temperature range of -55°C to 125°C with a rated lifetime of 2000 hours at 125°C.

Identifying equivalent and substitute parts is necessary when the primary part number becomes unavailable, when supply chain constraints occur, or when design revisions require components with improved compliance certifications while maintaining identical electrical and mechanical performance characteristics.

Substitute Part Grouping Explanation

Substitution eligibility for the T54EE157M030ESS075 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance value: 150 µF (exact match required)
• Rated voltage: 30 V (exact match required)
• ESR specification: 75 mOhm @ 100 kHz (exact match required)
• Tolerance: ±20% (exact match required)

Mechanical Parameters:

• Package designation: 2917 (7343 Metric) (exact match required)
• Mounting type: Surface Mount (exact match required)
• Physical dimensions: 0.287" L x 0.169" W (7.30 mm x 4.30 mm) (exact match required)
• Height - Seated (Max): 0.169" (4.30 mm) (exact match required)

Environmental & Reliability Parameters:

• Operating temperature range: -55°C ~ 125°C (exact match required)
• Lifetime rating: 2000 Hrs @ 125°C (exact match required)
• Moisture Sensitivity Level: 3 (168 Hours) (exact match required)

Series & Manufacturer:

• Series: vPolyTan™ T54 (exact match required)
• Manufacturer: Vishay Polytech (exact match required)

Substitute parts must satisfy all parameters listed above without exception. Variations in any single parameter disqualify a component from substitution eligibility.

Parameter Comparison

Engineering Selection Recommendations

The T54EE157M030CSA075 is a direct parametric equivalent to the T54EE157M030ESS075. All electrical, mechanical, and environmental specifications are identical across both part numbers. Both components are manufactured by Vishay Polytech within the vPolyTan™ T54 series and maintain identical performance characteristics in circuit applications.

The primary distinction between these two part numbers is the RoHS compliance status. The T54EE157M030ESS075 is RoHS non-compliant, while the T54EE157M030CSA075 is ROHS3 compliant. This difference reflects manufacturing process variations and material composition but does not alter the electrical or mechanical performance of the capacitor.

Selection between these two equivalent parts should be based on regulatory and compliance requirements applicable to the end application. If RoHS3 compliance is mandated by design specifications, supply chain requirements, or regional regulations, the T54EE157M030CSA075 is the appropriate selection. If RoHS compliance is not a requirement, either part number is functionally interchangeable.

Both parts are currently in active production status with confirmed inventory availability.

Frequently Asked Questions (FAQ)

Q: Can the T54EE157M030CSA075 be used as a direct replacement for the T54EE157M030ESS075 in existing designs?

A: Yes. The T54EE157M030CSA075 is a direct parametric equivalent. All electrical specifications, mechanical dimensions, package format, and performance characteristics are identical. No circuit modifications or PCB layout changes are required for substitution.

Q: What is the difference between these two part numbers?

A: The primary difference is RoHS compliance status. The T54EE157M030ESS075 is RoHS non-compliant, while the T54EE157M030CSA075 is ROHS3 compliant. All other specifications, including capacitance, voltage rating, ESR, package dimensions, and operating temperature range, are identical.

Q: Are the physical dimensions and PCB footprints identical?

A: Yes. Both components use the 2917 (7343 Metric) package format with identical dimensions of 0.287" L x 0.169" W (7.30 mm x 4.30 mm) and a maximum seated height of 0.169" (4.30 mm). PCB footprints are interchangeable without modification.

Q: Do these capacitors have the same ESR performance?

A: Yes. Both the T54EE157M030ESS075 and T54EE157M030CSA075 specify an ESR of 75 mOhm @ 100 kHz. Electrical performance in high-frequency applications is identical.

Q: What is the operating temperature range for both parts?

A: Both components operate across the temperature range of -55°C to 125°C with a rated lifetime of 2000 hours at 125°C. Thermal performance characteristics are identical.

Q: Are both parts currently available in inventory?

A: Yes. The T54EE157M030ESS075 has 858 pieces in stock, and the T54EE157M030CSA075 has 1024 pieces in stock. Both are listed as active products in current production.

Q: Which part should I select for a new design?

A: Selection should be based on compliance requirements. If RoHS3 compliance is required, select the T54EE157M030CSA075. If RoHS compliance is not a requirement, either part is functionally equivalent. For new designs, the ROHS3 compliant variant is recommended to ensure future regulatory alignment.
