Panasonic 4TCE220M Tantalum Polymer Capacitor Equivalent & Substitute Parts

Part Overview

The Panasonic 4TCE220M is a 220 µF molded tantalum polymer capacitor rated for 4 V operation in a 2917 (7343 Metric) surface mount package. This component is part of the POSCAP™ TC series and maintains an active product status. The 4TCE220M is specified for general purpose applications requiring low equivalent series resistance and stable performance across the operating temperature range of -55°C to 125°C. Substitute parts are identified to provide alternative sourcing options when the primary part number is unavailable or when inventory requirements necessitate alternative manufacturer stock.

Key Parameters

Substitute Part Grouping Explanation

The 4TCE220MF is identified as a parametric equivalent to the 4TCE220M based on matching electrical and mechanical specifications. Substitution eligibility is determined by the following criteria:

• Identical capacitance value: 220 µF
• Identical voltage rating: 4 V
• Identical tolerance: ±20%
• Identical ESR specification: 15 mOhm @ 100 kHz
• Identical package designation: 2917 (7343 Metric)
• Identical physical dimensions: 0.287" L × 0.169" W (7.30 mm × 4.30 mm)
• Identical maximum seated height: 0.079" (2.00 mm)
• Identical operating temperature range: -55°C to 125°C
• Identical lifetime rating: 1000 Hrs @ 125°C
• Identical mounting type: Surface Mount
• Identical series classification: POSCAP™ TC
• Identical RoHS compliance: ROHS3 Compliant

Both parts are manufactured by Panasonic Electronic Components and share the same base product number (4TCE), differing only in the final suffix designation.

Parameter Comparison

Engineering Selection Recommendations

Both the 4TCE220M and 4TCE220MF are active products manufactured by Panasonic Electronic Components and maintain ROHS3 compliance. Selection between these parts should be based on inventory availability and procurement lead times. The 4TCE220MF currently maintains higher inventory levels (8197 Pcs) compared to the 4TCE220M (3932 Pcs), which may influence sourcing decisions for high-volume applications. Both parts are suitable for direct substitution in applications requiring 220 µF tantalum polymer capacitors at 4 V with low ESR characteristics.

Frequently Asked Questions (FAQ)

Q: Can the 4TCE220MF be used as a direct replacement for the 4TCE220M?

A: Yes. Both parts share identical electrical specifications (220 µF, 4 V, ±20% tolerance, 15 mOhm ESR @ 100 kHz), mechanical dimensions (2917 package, 7.30 mm × 4.30 mm), and operating characteristics (-55°C to 125°C, 1000 Hrs @ 125°C). They are interchangeable in circuit design and PCB layout.

Q: Are there any differences in package or mounting between these parts?

A: No. Both parts use identical 2917 (7343 Metric) surface mount packages with matching physical dimensions and maximum seated heights. PCB footprints and assembly processes remain unchanged.

Q: What determines substitution eligibility for tantalum polymer capacitors?

A: Substitution is valid when capacitance, voltage rating, tolerance, ESR specification, package designation, physical dimensions, operating temperature range, and lifetime ratings are identical. Both the 4TCE220M and 4TCE220MF meet all these criteria.

Q: Are both parts RoHS compliant?

A: Yes. Both the 4TCE220M and 4TCE220MF are ROHS3 compliant and suitable for applications requiring environmental compliance.

Q: Which part should be selected based on availability?

A: Selection should be based on current inventory levels and procurement requirements. The 4TCE220MF maintains higher stock availability, which may provide shorter lead times for high-volume orders.
