T495D157K006ATE080 Equivalent & Substitute Parts

Part Overview

The T495D157K006ATE080 is a 150 µF molded tantalum capacitor manufactured by KEMET, rated for 6.3 V with ±10% tolerance. This surface mount component is housed in a 2917 (7343 Metric) package and features an equivalent series resistance (ESR) of 80 mOhm @ 100 kHz. The part is currently active in production and RoHS3 compliant. Substitute parts are identified when equivalent electrical and mechanical parameters are required due to inventory constraints, design revisions, or component availability.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the T495D157K006ATE080 are qualified based on matching the following critical parameters: capacitance value (150 µF), voltage rating (6.3 V), tolerance (±10%), package type (2917 / 7343 Metric), mounting configuration (surface mount), operating temperature range (-55°C ~ 125°C), and lifetime specification (2000 Hrs @ 125°C).

The identified substitutes maintain electrical compatibility through identical capacitance, voltage, and tolerance specifications. Physical compatibility is ensured through identical package dimensions and mounting type. Variations in ESR (equivalent series resistance) and regulatory compliance status are noted as distinguishing factors between the main part and substitutes, as these parameters may influence circuit performance and application suitability.

Parameter Comparison

Engineering Selection Recommendations

T495D157K006ATE080 (Primary Part)

This part is the baseline reference and is RoHS3 compliant. It is suitable for applications requiring regulatory compliance with modern environmental standards. The 80 mOhm ESR @ 100 kHz provides moderate impedance characteristics for general purpose tantalum capacitor applications.

T495D157K006ATE050 (Preferred Substitute)

This substitute maintains full electrical and mechanical compatibility with the primary part. It is RoHS3 compliant, matching the regulatory status of the original part. The 50 mOhm ESR @ 100 kHz is lower than the primary part, resulting in reduced impedance. This characteristic may be beneficial in applications where lower ESR is advantageous. Selection of this part is appropriate when the primary part is unavailable and lower ESR performance is acceptable or desirable.

T491D157K006AH (Alternative Substitute)

This substitute provides electrical and mechanical compatibility in terms of capacitance, voltage, tolerance, package, and thermal specifications. However, it is RoHS non-compliant, which restricts its use in applications subject to RoHS regulations. Additionally, the 700 mOhm ESR @ 100 kHz is significantly higher than the primary part, which may impact circuit performance in applications sensitive to impedance. This part is suitable only for legacy designs or applications where RoHS compliance is not required.

Frequently Asked Questions (FAQ)

Q: Can T495D157K006ATE050 be used as a direct replacement for T495D157K006ATE080?

A: Yes. Both parts share identical capacitance (150 µF), voltage rating (6.3 V), tolerance (±10%), package dimensions (2917 / 7343 Metric), operating temperature range (-55°C ~ 125°C), and lifetime specification (2000 Hrs @ 125°C). The primary difference is ESR: T495D157K006ATE050 has 50 mOhm @ 100 kHz compared to 80 mOhm @ 100 kHz for the primary part. Both are RoHS3 compliant.

Q: Why is T491D157K006AH listed as a substitute if it has higher ESR?

A: T491D157K006AH meets the core electrical and mechanical compatibility criteria: identical capacitance, voltage, tolerance, package, and thermal specifications. However, the significantly higher ESR (700 mOhm) and RoHS non-compliance status make it suitable only for applications where these differences are acceptable or where RoHS compliance is not required.

Q: Are all substitute parts physically interchangeable?

A: Yes. All three parts use the 2917 (7343 Metric) package with identical dimensions: 0.287" L x 0.169" W (7.30mm x 4.30mm) and maximum seated height of 0.122" (3.10mm). All are surface mount components suitable for the same PCB footprint.

Q: What is the impact of ESR differences between these parts?

A: ESR affects impedance characteristics at operating frequencies. Lower ESR (T495D157K006ATE050 at 50 mOhm) results in reduced impedance and may improve performance in high-frequency or low-impedance applications. Higher ESR (T491D157K006AH at 700 mOhm) increases impedance and may be unsuitable for applications requiring low impedance characteristics.

Q: Which substitute should be selected for new designs?

A: For new designs, T495D157K006ATE050 is the preferred substitute when the primary part is unavailable. It maintains RoHS3 compliance and provides lower ESR performance. T491D157K006AH should be avoided in new designs due to RoHS non-compliance unless legacy compatibility is explicitly required.

Q: Are moisture sensitivity levels identical across all parts?

A: Yes. All three parts have Moisture Sensitivity Level (MSL) 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
