Key Parameters

Substitute Part Grouping Explanation

Substitution of the T86C155K035EBAS is determined by strict equivalence across the following electrical and mechanical parameters:

• Capacitance value: 1.5 µF
• Tolerance: ±10%
• Rated voltage: 35 V
• ESR: 3.8 Ohm
• Package type: 2312 (6032 Metric)
• Physical dimensions: 0.236" L x 0.126" W (6.00mm x 3.20mm)
• Operating temperature range: -55°C to 125°C
• Mounting type: Surface Mount
• Molded tantalum construction

The substitute part 293D155X9035C2TE3 meets all these criteria and is therefore electrically and mechanically interchangeable.

Parameter Comparison

Engineering Selection Recommendations

The 293D155X9035C2TE3 is the direct equivalent substitute for the obsolete T86C155K035EBAS. Both parts are manufactured by Vishay Sprague and share identical electrical specifications and mechanical dimensions. The substitute part is currently in active production status, ensuring supply chain continuity.

The primary distinction between the two parts is regulatory compliance. The substitute part 293D155X9035C2TE3 is ROHS3 compliant, whereas the original T86C155K035EBAS is RoHS non-compliant. For applications subject to RoHS regulations, the substitute part is the appropriate selection. Both parts maintain identical MSL ratings and REACH unaffected status.

Frequently Asked Questions (FAQ)

Q: Can the 293D155X9035C2TE3 be used as a direct replacement for the T86C155K035EBAS?

A: Yes. Both parts are electrically and mechanically equivalent. They share identical capacitance (1.5 µF), voltage rating (35 V), ESR (3.8 Ohm), package dimensions (2312/6032 Metric), and operating temperature range (-55°C to 125°C). The substitute part is pin-compatible and requires no circuit modifications.

Q: What is the difference in height between these two parts?

A: The seated height difference is minimal: T86C155K035EBAS is 0.110" (2.80mm) maximum, while 293D155X9035C2TE3 is 0.110" (2.79mm) maximum. This 0.01mm difference is within standard PCB assembly tolerances and does not affect compatibility.

Q: Why is the substitute part ROHS3 compliant while the original is not?

A: The original T86C155K035EBAS is an obsolete part manufactured under earlier specifications. The 293D155X9035C2TE3 represents the current production equivalent and incorporates modern RoHS3 compliance standards. Both parts are functionally identical for electrical performance.

Q: Are there any packaging differences between these parts?

A: The T86C155K035EBAS is supplied in standard packaging, while the 293D155X9035C2TE3 is available in Tape & Reel (TR) format. Both use the same 2312 (6032 Metric) surface mount package. The TR packaging is standard for high-volume production environments.

Q: What is the moisture sensitivity level for both parts?

A: Both parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard handling procedures apply without special storage or baking requirements.
