Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLCL476M004RTA is determined by strict equivalence in the following parameters:

• Capacitance: 47 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Voltage Rating: 4 V (exact match required)
• Package / Case: 0603 (1608 Metric) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)

The identified substitute parts maintain all critical electrical and mechanical parameters. Variations in ESR (Equivalent Series Resistance), MSL (Moisture Sensitivity Level), and physical height are noted but do not preclude substitution when the above parameters are matched.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts maintain full electrical and mechanical compatibility with the TLCL476M004RTA. Selection between alternatives is based on the following criteria:

298D476X0004M2T (Vishay Sprague MICROTAN® 298D Series): This part provides direct electrical equivalence with matching 7.5 Ohm ESR. It features improved moisture sensitivity (MSL 1 vs. MSL 3) and reduced seated height (0.89mm vs. 1.00mm), offering enhanced reliability in moisture-prone environments and improved PCB assembly clearance margins.

TR8M476M004C1500 (Vishay Sprague MICROTAN® TR8 Series): This part offers superior ESR performance at 1.5 Ohm, providing lower impedance characteristics beneficial for high-frequency filtering applications. It also features MSL 1 rating and reduced seated height. Selection of this part is appropriate when lower ESR is a circuit requirement.

All three parts are Active status products with ROHS3 compliance and REACH Unaffected designation, ensuring regulatory alignment and long-term supply continuity.

Frequently Asked Questions (FAQ)

Q: Can 298D476X0004M2T directly replace TLCL476M004RTA on the PCB?

A: Yes. Both parts share identical capacitance (47 µF), tolerance (±20%), voltage rating (4 V), package (0603), and operating temperature range (-55°C ~ 125°C). The 298D476X0004M2T features lower seated height (0.89mm vs. 1.00mm), which improves PCB assembly clearance without affecting electrical performance.

Q: What is the difference between the two Vishay Sprague substitutes?

A: The primary difference is ESR (Equivalent Series Resistance). The 298D476X0004M2T maintains 7.5 Ohm ESR matching the original part, while the TR8M476M004C1500 provides 1.5 Ohm ESR. Lower ESR reduces impedance and heat generation, beneficial for applications requiring superior high-frequency filtering. Both parts are electrically and mechanically compatible.

Q: Are there any height restrictions I should consider?

A: The TLCL476M004RTA has a maximum seated height of 1.00mm. Both substitute parts are 0.89mm, which is lower. If your PCB design has height constraints, the substitutes provide additional clearance margin. If your design requires exact height matching, verify clearance with your assembly process documentation.

Q: Do the substitute parts have different moisture sensitivity requirements?

A: Yes. The TLCL476M004RTA is MSL 3 (168 Hours), while both Vishay Sprague substitutes are MSL 1 (Unlimited). MSL 1 provides superior moisture resistance and eliminates time-based storage constraints, offering operational advantages in humid environments and extended shelf-life scenarios.

Q: Are all three parts ROHS3 compliant?

A: Yes. The TLCL476M004RTA, 298D476X0004M2T, and TR8M476M004C1500 are all ROHS3 compliant and REACH Unaffected, ensuring regulatory compliance across all substitution options.
