Key Parameters

Substitute Part Grouping Explanation

Substitution grouping is strictly determined by matching the following key parameters: capacitance (1.5 µF), rated voltage (35 V), package/case (2312 / 6032 Metric), mounting type (surface mount), size/dimensions (0.236" x 0.126"), and tolerance (±20%). Features, series, ESR values, and compliance ratings are referenced as provided. Only parts that exactly replicate these attributes are considered direct substitutes. All relationships are based on explicit parameter matches in the provided data.

Parameter Comparison

Engineering Selection Recommendations

The T86C155M035ESSL is obsolete and RoHS non-compliant. The substitute part TH3C155M035D3300 maintains equivalent capacitance, voltage, tolerance, size, package, and mounting type. It is listed as ROHS3 compliant and is active in production. Selection should be strictly based on provided part status and compliance ratings, as required by assembly or regulatory obligations.

Frequently Asked Questions (FAQ)

Q: What are the key criteria for substituting T86C155M035ESSL?
A: Direct substitution requires identical capacitance (1.5 µF), voltage rating (35 V), tolerance (±20%), package (2312 / 6032 Metric), mounting type (surface mount), and physical size.

Q: Are ESR and operating temperature range required to match exactly?
A: Substitute groupings are determined by provided core parameters: capacitance, voltage, tolerance, package/case, mounting, and size. ESR and operating temperature ranges are referenced as listed.

Q: Is there any difference in compliance between these parts?
A: T86C155M035ESSL is RoHS non-compliant, while TH3C155M035D3300 is ROHS3 compliant.

Q: Does the substitute have the same physical footprint?
