Key Parameters

Substitute Part Grouping Explanation

Substitution of the T86C155M035EBAS is determined by strict equivalence across the following electrical and mechanical parameters:

• Capacitance value: 1.5 µF
• Tolerance: ±20%
• Voltage rating: 35 V
• ESR: 3.8 Ohm
• Operating temperature range: -55°C to 125°C
• Package type: 2312 (6032 Metric) surface mount
• Physical dimensions: 0.236" L × 0.126" W with maximum seated height of 0.110"
• Moisture sensitivity: MSL 1

The substitute part 293D155X0035C2TE3 meets all these criteria and is therefore electrically and mechanically interchangeable with the original component.

Parameter Comparison

Engineering Selection Recommendations

The 293D155X0035C2TE3 is the direct functional equivalent for the obsolete T86C155M035EBAS. Both components share identical electrical specifications and mechanical dimensions, ensuring pin-for-pin and footprint compatibility.

The substitute part offers the advantage of active product status, ensuring continued availability and supply chain stability. Additionally, the 293D155X0035C2TE3 carries RoHS3 compliance, whereas the original part is RoHS non-compliant. This distinction is relevant for applications subject to RoHS regulatory requirements.

Selection between these parts should be based on regulatory compliance requirements and supply availability. For new designs or systems requiring RoHS compliance, the 293D155X0035C2TE3 is the appropriate choice. For legacy system maintenance where RoHS compliance is not mandated, either part is functionally equivalent.

Frequently Asked Questions (FAQ)

Q: Can the 293D155X0035C2TE3 be used as a direct replacement for the T86C155M035EBAS?

A: Yes. Both parts are identical in capacitance (1.5 µF), voltage rating (35 V), ESR (3.8 Ohm), operating temperature range (-55°C to 125°C), and package dimensions (2312 / 6032 Metric). They are electrically and mechanically interchangeable.

Q: What is the difference between these two parts?

A: The primary differences are product status and regulatory compliance. The T86C155M035EBAS is obsolete and RoHS non-compliant. The 293D155X0035C2TE3 is an active product with RoHS3 compliance. Electrical and mechanical specifications are identical.

Q: Are there any height or footprint differences?

A: Maximum seated height differs by 0.01 mm (2.80 mm vs. 2.79 mm), which is within standard PCB assembly tolerances and does not affect compatibility. All other physical dimensions are identical.

Q: What packaging options are available for the substitute part?

A: The 293D155X0035C2TE3 is supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes.

Q: Is the MSL rating the same for both parts?

A: Yes. Both parts carry MSL 1 (Unlimited) moisture sensitivity rating, indicating no special moisture handling requirements during storage or assembly.
