ECS-H1CC475R Equivalent & Substitute Parts

Part Overview

The ECS-H1CC475R is a 4.7 µF molded tantalum capacitor manufactured by Panasonic Electronic Components, rated for 16 V operation in a 2312 (6032 Metric) surface mount package. This component is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement continuity. Substitute parts must maintain electrical equivalence across capacitance, voltage rating, tolerance, and operating temperature specifications while accommodating package and mechanical variations.

Substitute Part Grouping Explanation

Substitution eligibility for the ECS-H1CC475R is determined by strict equivalence across the following parameters: capacitance value (4.7 µF), voltage rating (minimum 16 V), tolerance (±20% or tighter), operating temperature range (-55°C ~ 125°C), and surface mount configuration. Package size variations are permissible when mechanical constraints of the application allow, provided all electrical specifications remain equivalent or superior.

Three substitute parts meet these criteria:

Direct Electrical Equivalent (Different Package): TAJB475M016RNJ maintains identical capacitance, voltage, tolerance, and temperature specifications in a smaller 1411 (3528 Metric) package with improved ESR characteristics.

Electrical Equivalent with Enhanced Voltage Rating (Same Package): TAJC475K035RNJ provides the same capacitance and package footprint as the main part with a higher 35 V voltage rating and tighter ±10% tolerance, suitable for applications requiring additional voltage margin.

Electrical Equivalent (Smaller Package): 293D475X0016A2TE3 maintains electrical equivalence in a compact 1206 (3216 Metric) package with superior ESR performance.

Parameter Comparison

Engineering Selection Recommendations

TAJB475M016RNJ is the preferred direct electrical substitute when PCB layout permits package downsizing. This part maintains all electrical specifications while offering improved ESR performance (4.6 Ohm) and active product status with ROHS3 compliance. The smaller 1411 package reduces board space requirements.

TAJC475K035RNJ is the optimal choice for applications requiring identical footprint compatibility with the original ECS-H1CC475R. This part provides the same 2312 package dimensions, enhanced voltage rating (35 V), tighter tolerance (±10%), and superior ESR characteristics (2.2 Ohm). ROHS3 compliance and active status ensure long-term availability.

293D475X0016A2TE3 serves applications where maximum board space efficiency is critical. The compact 1206 package accommodates the smallest footprint while maintaining full electrical equivalence. ESR performance (5 Ohm) remains within acceptable parameters for general-purpose applications.

All three substitutes provide ROHS3 compliance, addressing regulatory requirements beyond the original obsolete component. Selection should prioritize TAJC475K035RNJ for direct footprint replacement or TAJB475M016RNJ for space-optimized designs.

Frequently Asked Questions (FAQ)

Q: Can TAJB475M016RNJ replace ECS-H1CC475R in existing designs without circuit modification?

A: Yes. TAJB475M016RNJ maintains identical electrical specifications (4.7 µF, 16 V, ±20%, -55°C ~ 125°C). PCB layout modification is required due to package size reduction from 2312 to 1411 (3528 Metric). No circuit changes are necessary.

Q: What is the primary advantage of TAJC475K035RNJ over the original part?

A: TAJC475K035RNJ provides identical package footprint (2312), enabling direct PCB replacement without layout modification. Additional benefits include higher voltage rating (35 V vs. 16 V), tighter tolerance (±10% vs. ±20%), lower ESR (2.2 Ohm), and ROHS3 compliance.

Q: Are all substitute parts rated for the same operating temperature range?

A: Yes. All substitute parts maintain the -55°C ~ 125°C operating temperature range specified for the original ECS-H1CC475R.

Q: What does ESR (Equivalent Series Resistance) indicate for capacitor selection?

A: ESR affects capacitor performance in high-frequency applications and ripple current handling. Lower ESR values indicate better performance. TAJC475K035RNJ (2.2 Ohm) offers superior ESR compared to TAJB475M016RNJ (4.6 Ohm) and 293D475X0016A2TE3 (5 Ohm).

Q: Is RoHS compliance a critical factor for this substitution?

A: RoHS compliance depends on application requirements and regulatory jurisdiction. All active substitute parts (TAJB475M016RNJ, 293D475X0016A2TE3, TAJC475K035RNJ) are ROHS3 compliant, while the original ECS-H1CC475R is RoHS non-compliant. New designs should prioritize compliant alternatives.

Q: Can 293D475X0016A2TE3 be used in space-constrained applications?

A: Yes. The 1206 (3216 Metric) package is the smallest among all options, with dimensions of 0.126" L x 0.063" W and maximum height of 0.071". This part is suitable for high-density PCB layouts where board space is limited.

Q: What is Moisture Sensitivity Level (MSL) 1, and does it affect handling?

A: MSL 1 indicates unlimited shelf life without moisture exposure precautions. All parts in this comparison carry MSL 1 rating, requiring no special moisture control during storage or handling.
