T54EE157M030CSS150 Equivalent & Substitute Parts

Part Overview

The T54EE157M030CSS150 is a 150 µF molded tantalum polymer capacitor rated for 30 V operation, manufactured by Vishay Polytech in the vPolyTan™ T54 series. This component is designed for surface mount applications in the 2917 (7343 Metric) package format. The part maintains an active product status and is ROHS3 compliant, making it suitable for modern electronic assemblies requiring high-reliability capacitive storage with low equivalent series resistance characteristics.

Substitute parts are identified when design requirements, inventory constraints, or supply chain considerations necessitate alternative sourcing while maintaining electrical and mechanical compatibility within the specified parameter tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the T54EE157M030CSS150 are identified based on strict electrical and mechanical parameter matching. The substitution criteria are defined by the following key parameters:

Electrical Parameters:

• Capacitance: 150 µF (exact match required)
• Voltage Rating: 30 V (exact match required)
• Tolerance: ±20% (exact match required)
• ESR @ 100kHz: 150 mOhm (exact match required)
• Operating Temperature Range: -55°C to 125°C (exact match required)
• Lifetime @ 125°C: 2000 Hrs (exact match required)

Mechanical Parameters:

• Package / Case: 2917 (7343 Metric) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Type: Molded (exact match required)

Compliance Parameters:

• RoHS Status: ROHS3 Compliant (exact match required)
• MSL Rating: 3 (168 Hours) (exact match required)

Parts meeting all specified parameters are classified as parametric equivalents and direct substitutes. The T54EE157M030CSA150 satisfies all substitution criteria and is therefore qualified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the T54EE157M030CSS150 and T54EE157M030CSA150 are active products manufactured by Vishay Polytech within the vPolyTan™ T54 series. Both components carry ROHS3 compliance certification and maintain identical electrical, mechanical, and thermal specifications.

Selection between these parts is based on availability and supply chain considerations rather than technical differentiation. The T54EE157M030CSA150 currently maintains higher inventory levels (1031 Pcs) compared to the T54EE157M030CSS150 (767 Pcs), which may influence procurement decisions when lead time or stock availability is a factor.

Both parts are suitable for direct substitution in applications requiring 150 µF capacitance at 30 V with 150 mOhm ESR characteristics in the 2917 surface mount package format. No design modifications, circuit adjustments, or additional validation testing are required when substituting between these parts.

Frequently Asked Questions (FAQ)

Q: Are T54EE157M030CSS150 and T54EE157M030CSA150 electrically interchangeable?

A: Yes. Both parts are parametric equivalents with identical capacitance (150 µF), voltage rating (30 V), tolerance (±20%), ESR (150 mOhm @ 100kHz), operating temperature range (-55°C to 125°C), and lifetime specifications (2000 Hrs @ 125°C). No circuit modifications are required for substitution.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes. Both components share identical mechanical specifications: 2917 (7343 Metric) package, surface mount mounting type, and identical physical dimensions (0.287" L x 0.169" W, 4.30mm height). PCB footprints, assembly processes, and reflow profiles remain unchanged.

Q: What is the difference between the T54EE157M030CSS150 and T54EE157M030CSA150 part numbers?

A: The part numbers differ only in the packaging designation suffix (CSS versus CSA). Both designations indicate Tape & Reel (TR) packaging format. The electrical and mechanical specifications are identical.

Q: Are both parts ROHS3 compliant?

A: Yes. Both T54EE157M030CSS150 and T54EE157M030CSA150 are ROHS3 compliant and suitable for applications requiring RoHS certification.

Q: What is the MSL rating for these capacitors?

A: Both parts carry MSL (Moisture Sensitivity Level) rating of 3 with a 168-hour floor life. Standard moisture control procedures during storage and handling are required.

Q: Can these parts be used in high-reliability applications?

A: Yes. Both components are rated as COTS (Commercial Off-The-Shelf) with high reliability features and are suitable for applications requiring consistent performance across the -55°C to 125°C operating temperature range.
