Engineering Selection Recommendations

T495D157K006ATE050 (Preferred Substitute)

The T495D157K006ATE050 maintains full compliance with RoHS3 standards and REACH regulations, matching the main part T495D157M006ATE080. This substitute offers improved ESR performance at 50 mOhm @ 100kHz compared to the main part's 80 mOhm, with tighter tolerance at ±10%. Both parts share identical package dimensions, operating temperature range, and lifetime specifications. Selection of this substitute is appropriate for applications requiring enhanced electrical performance and regulatory compliance continuity.

T491D157K006AH (Alternative Substitute)

The T491D157K006AH provides equivalent capacitance, voltage rating, and package configuration. However, this part is RoHS non-compliant, which may restrict its use in applications subject to RoHS3 regulatory requirements. The ESR specification of 700 mOhm @ 100kHz is significantly higher than the main part. This substitute is suitable only for applications where RoHS compliance is not mandated and where higher ESR is acceptable.

Frequently Asked Questions (FAQ)

Q: Can T495D157K006ATE050 be used as a direct replacement for T495D157M006ATE080?

A: Yes. Both parts share identical capacitance (150 µF), voltage rating (6.3 V), package configuration (2917 / 7343 Metric), operating temperature range (-55°C ~ 125°C), and lifetime specifications (2000 Hrs @ 125°C). The T495D157K006ATE050 offers superior ESR performance and maintains RoHS3 compliance.

Q: What is the significance of the tolerance difference between ±20% and ±10%?

A: Tolerance specifies the allowable deviation of actual capacitance from the nominal 150 µF value. The ±10% tolerance of substitute parts provides tighter capacitance accuracy compared to the ±20% tolerance of the main part. This tighter tolerance may be beneficial in precision applications but does not prevent substitution in general-purpose circuits.

Q: Why is ESR (Equivalent Series Resistance) important in capacitor selection?

A: ESR affects the capacitor's impedance at operating frequencies and influences ripple current handling, voltage drop, and thermal performance. The main part specifies 80 mOhm @ 100kHz. The T495D157K006ATE050 substitute at 50 mOhm provides lower impedance, while the T491D157K006AH at 700 mOhm presents significantly higher impedance. ESR selection depends on circuit requirements for frequency response and current handling.

Q: Are there any compliance differences between the substitute parts?

A: Yes. The T495D157K006ATE050 is RoHS3 compliant, matching the main part. The T491D157K006AH is RoHS non-compliant. Both parts are REACH Unaffected. Applications subject to RoHS3 regulatory requirements must use either the main part or the T495D157K006ATE050.

Q: Do all three parts fit the same PCB footprint?

A: Yes. All three parts share identical package designation (2917 / 7343 Metric), physical dimensions (0.287" L x 0.169" W / 7.30mm x 4.30mm), and maximum seated height (0.122" / 3.10mm). PCB footprints are interchangeable.

Q: What is the Moisture Sensitivity Level (MSL) rating?

A: All three parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. These components do not require special moisture control during storage, handling, or assembly.
