ETPH100MHA Equivalent & Substitute Parts

Part Overview

The ETPH100MHA is a 100 µF molded tantalum polymer capacitor manufactured by Panasonic Electronic Components, rated at 2.5 V with a 1206 (3216 Metric) surface mount package. This component is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and production continuity. The POSCAP™ TPH series capacitor features 150mOhm ESR at 100kHz and operates across -55°C to 105°C with a 1000-hour lifetime rating at 105°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ETPH100MHA is determined by the following critical parameters:

Capacitance value must remain 100 µF. Voltage rating must equal or exceed 2.5 V to maintain circuit safety margins. Package type must be 1206 (3216 Metric) to ensure mechanical and electrical compatibility with existing PCB layouts. Mounting type must be surface mount. Operating temperature range must encompass -55°C to 105°C. Type classification must be molded tantalum polymer. RoHS3 compliance is required for regulatory alignment.

The substitute part T520A107M006ATE070 meets all these criteria while offering improved electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The T520A107M006ATE070 is a direct functional substitute for the ETPH100MHA. Both components share identical capacitance, tolerance, package dimensions, and operating temperature specifications. The substitute part carries active product status from KEMET, ensuring continued availability and supply chain stability compared to the obsolete Panasonic component.

The T520A107M006ATE070 provides superior electrical performance with 70mOhm ESR versus 150mOhm ESR, and extended lifetime rating of 2000 hours at 105°C versus 1000 hours. The higher voltage rating of 6.3 V provides additional design margin in 2.5 V applications. Both components maintain ROHS3 compliance and identical moisture sensitivity classification.

Physical height difference of 0.032" (0.80mm) must be verified against PCB clearance requirements and component placement constraints in the target assembly.

Frequently Asked Questions (FAQ)

Q: Can the T520A107M006ATE070 directly replace the ETPH100MHA in existing designs?

A: Yes. Both components share identical capacitance (100 µF), tolerance (±20%), package type (1206), operating temperature range (-55°C to 105°C), and mounting configuration (surface mount). The substitute part meets all electrical and mechanical compatibility requirements for direct substitution.

Q: What is the significance of the voltage rating difference?

A: The ETPH100MHA is rated at 2.5 V while the T520A107M006ATE070 is rated at 6.3 V. In a 2.5 V application, the higher-rated substitute provides additional voltage margin and does not create compatibility issues. The capacitor will function correctly at or below its rated voltage.

Q: Does the height difference affect PCB assembly?

A: The T520A107M006ATE070 has a maximum seated height of 0.071" (1.80mm) compared to 0.039" (1.00mm) for the ETPH100MHA. This 0.032" (0.80mm) difference must be evaluated against available PCB clearance, component stacking requirements, and assembly equipment specifications.

Q: Why is the substitute part preferred despite the height difference?

A: The T520A107M006ATE070 offers active product status, lower ESR (70mOhm versus 150mOhm), and extended lifetime rating (2000 hours versus 1000 hours at 105°C). These performance improvements justify the height consideration in applications where clearance permits.

Q: Are both components RoHS compliant?

A: Yes. Both the ETPH100MHA and T520A107M006ATE070 are ROHS3 compliant and carry identical Moisture Sensitivity Level 3 (168 Hours) classification.
