Substitute Part Grouping Explanation

Substitution of the T86C155M035EBAL is determined by strict equivalence across the following parameters:

• Capacitance value: 1.5 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Voltage rating: 35 V (exact match required)
• Package / Case: 2312 (6032 Metric) (exact match required)
• Physical dimensions: 0.236" L x 0.126" W, height 0.110" max (exact match required)
• Mounting type: Surface Mount (exact match required)
• Manufacturer size code: C (exact match required)

The substitute part TH3C155M035D3300 meets all these core electrical and mechanical parameters, enabling direct functional replacement in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

The TH3C155M035D3300 serves as a direct functional substitute for the obsolete T86C155M035EBAL. Both components share identical electrical specifications (1.5 µF, ±20%, 35 V) and mechanical form factors (2312 package, surface mount).

The substitute part offers the following advantages:

• Active product status ensures ongoing availability and supply chain continuity
• ROHS3 compliance meets current environmental and regulatory requirements
• Extended operating temperature range (-55°C ~ 150°C) provides broader thermal performance envelope
• Equivalent series resistance of 3.3 Ohm remains within acceptable operational parameters for tantalum capacitor applications

The substitute part is suitable for direct replacement in applications where the original T86C155M035EBAL was specified.

Frequently Asked Questions (FAQ)

Q: Can TH3C155M035D3300 be used as a direct replacement for T86C155M035EBAL?

A: Yes. Both parts share identical capacitance (1.5 µF), tolerance (±20%), voltage rating (35 V), and package format (2312 / 6032 Metric). Physical dimensions and mounting characteristics are equivalent, enabling direct PCB-level substitution.

Q: What is the difference in ESR between these parts?

A: The T86C155M035EBAL has an ESR of 2.6 Ohm, while the TH3C155M035D3300 has an ESR of 3.3 Ohm. This 0.7 Ohm difference is within normal manufacturing variation for molded tantalum capacitors and does not affect functional compatibility in standard circuit applications.

Q: Does the extended temperature range of the substitute part affect compatibility?

A: No. The substitute part's operating range of -55°C ~ 150°C encompasses the original part's range of -55°C ~ 125°C. The extended upper temperature limit provides additional thermal margin without compromising compatibility.

Q: Are there packaging differences between these parts?

A: The T86C155M035EBAL is supplied in standard packaging, while the TH3C155M035D3300 is supplied in Tape & Reel (TR) format. Both use identical component form factors and are compatible with standard surface mount assembly processes.

Q: What is the RoHS compliance status of each part?

A: The T86C155M035EBAL is RoHS non-compliant. The TH3C155M035D3300 is ROHS3 compliant, meeting current environmental regulations for new designs and production applications.
