6TPE150MI Equivalent & Substitute Parts

Part Overview

The 6TPE150MI is a 150 µF molded tantalum polymer capacitor manufactured by Panasonic Electronic Components, part of the POSCAP™ TPE series. This surface mount capacitor operates at 6.3 V with an equivalent series resistance of 18 mOhm @ 100 kHz and is housed in a 2917 (7343 Metric) package. The component is actively produced and ROHS3 compliant. Identifying equivalent substitute parts is necessary for supply chain continuity, inventory management, and design flexibility when the primary part becomes unavailable or when alternative sourcing is required.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 6TPE150MI are determined by strict equivalence across the following critical parameters:

• Capacitance value: 150 µF (exact match required)
• Voltage rating: 6.3 V (exact match required)
• ESR specification: 18 mOhm @ 100 kHz (exact match required)
• Package / Case: 2917 (7343 Metric) (exact match required)
• Operating temperature range: -55°C ~ 105°C (exact match required)
• Lifetime specification: 2000 Hrs @ 105°C (exact match required)
• Mounting type: Surface Mount (exact match required)
• Type: Molded tantalum polymer (exact match required)
• Tolerance: ±20% (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)

The substitute part T520V157M006ATE018 from KEMET meets all these criteria and is therefore a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the 6TPE150MI and T520V157M006ATE018 are active production components with ROHS3 compliance and identical electrical and mechanical specifications. The substitute part T520V157M006ATE018 is suitable for direct replacement in applications requiring a 150 µF, 6.3 V molded tantalum polymer capacitor with 18 mOhm ESR. The minor difference in seated height (0.079" versus 0.075") is within acceptable tolerances for standard PCB assembly processes and does not affect functional compatibility. Both parts are available in Tape & Reel packaging for automated assembly.

Frequently Asked Questions (FAQ)

Q: Can T520V157M006ATE018 be used as a direct replacement for 6TPE150MI?

A: Yes. Both parts share identical electrical specifications (150 µF, 6.3 V, 18 mOhm ESR), operating temperature range (-55°C ~ 105°C), lifetime rating (2000 Hrs @ 105°C), package type (2917 / 7343 Metric), and compliance certifications (ROHS3). They are functionally equivalent.

Q: Are there any physical compatibility concerns?

A: The seated height differs by 0.004" (0.10 mm), with T520V157M006ATE018 being slightly shorter. This difference is negligible for standard PCB assembly and does not affect mounting or electrical performance.

Q: Do both parts have the same tolerance?

A: Yes. Both the 6TPE150MI and T520V157M006ATE018 have a capacitance tolerance of ±20%.

Q: What is the significance of the package designation 2917 (7343 Metric)?

A: The 2917 package is the IPC designation, and 7343 Metric is the metric equivalent. Both parts use this identical package, ensuring mechanical and electrical compatibility on the PCB.

Q: Are both parts RoHS compliant?

A: Yes. Both the 6TPE150MI and T520V157M006ATE018 are ROHS3 compliant, meeting environmental and regulatory requirements for electronic components.
