6TPH47MHA Equivalent & Substitute Parts

Part Overview

The Panasonic 6TPH47MHA is a 47 µF molded tantalum polymer capacitor rated at 6.3 V in a 1206 (3216 Metric) surface mount package. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and production continuity. The part operates across a temperature range of -55°C to 105°C with an ESR of 150 mOhm @ 100 kHz and is RoHS3 compliant with MSL 3 moisture sensitivity rating.

Substitute Part Grouping Explanation

Substitution for the 6TPH47MHA is determined by strict electrical and mechanical compatibility criteria. All substitute parts must meet the following requirements:

Core Compatibility Parameters:

Capacitance: 47 µF (±20% tolerance acceptable)
Voltage Rating: 6.3 V minimum
Package: 1206 (3216 Metric) surface mount
Type: Molded tantalum polymer
Operating Temperature: -55°C ~ 105°C minimum range
RoHS3 Compliance
MSL 3 rating

Electrical Performance Consideration: ESR values may vary between manufacturers. The original part specifies 150 mOhm @ 100 kHz. Substitute parts with higher ESR values (such as 500 mOhm) remain functionally equivalent provided all other electrical and mechanical parameters align and the application does not impose strict ESR requirements.

Two active substitute parts meet these criteria and are grouped as direct equivalents based on matching capacitance, voltage, package, temperature range, and compliance certifications.

Engineering Selection Recommendations

TCJK476M006R0150E (KYOCERA AVX) is the primary substitute for the 6TPH47MHA. This part maintains identical electrical specifications including 150 mOhm ESR, matching physical dimensions (0.039" seated height), and carries active product status with full RoHS3 and REACH compliance. The KYOCERA AVX part provides the closest functional equivalence with no performance trade-offs.

T55A476M6R3C0500 (Vishay Sprague) is an alternative substitute with active product status and full compliance certifications. This part differs in ESR (500 mOhm vs. 150 mOhm) and seated height (0.071" vs. 0.039"), making it suitable for applications where ESR is not a critical design parameter and PCB layout accommodates the increased height. The higher ESR may impact performance in noise-sensitive or high-frequency ripple current applications.

Both substitute parts are RoHS3 compliant and carry MSL 3 ratings, ensuring compatibility with standard manufacturing processes.

Frequently Asked Questions (FAQ)

Q: Can I use T55A476M6R3C0500 as a direct replacement for 6TPH47MHA?

A: T55A476M6R3C0500 is electrically compatible in terms of capacitance, voltage, and temperature range. However, it has higher ESR (500 mOhm vs. 150 mOhm) and greater seated height (0.071" vs. 0.039"). Verify that your application tolerates the increased ESR and that PCB layout accommodates the taller component profile.

Q: What is the difference between the two substitute parts?

A: TCJK476M006R0150E matches the original ESR specification (150 mOhm) and physical height (0.039"), providing direct equivalence. T55A476M6R3C0500 has higher ESR (500 mOhm) and greater height (0.071"), suitable for less demanding applications where these differences do not affect circuit performance.

Q: Are both substitute parts in active production?

A: Yes. TCJK476M006R0150E and T55A476M6R3C0500 are both active products with current inventory availability, ensuring long-term supply continuity compared to the obsolete 6TPH47MHA.

Q: Do the substitute parts meet the same compliance standards?

A: Both substitute parts are RoHS3 compliant with MSL 3 moisture sensitivity ratings, matching the original part's compliance profile. TCJK476M006R0150E also carries REACH Unaffected status.

Q: Will the increased height of T55A476M6R3C0500 cause assembly issues?

A: The 0.071" seated height of T55A476M6R3C0500 exceeds the original 0.039" specification. Verify PCB layout, component clearances, and assembly equipment compatibility before selection. TCJK476M006R0150E maintains the original height and eliminates this consideration.
