Substitute Part Grouping Explanation

Substitution of the ESRH101M06R is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Capacitance: 100 µF (exact match required)
• Voltage Rating: 6.3 V (exact match required)
• Package / Case: 2917 (7343 Metric) (exact match required)
• Type: Aluminum - Polymer (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Operating Temperature Range: -55°C ~ 105°C (minimum required)
• Tolerance: ±20% (exact match required)

Allowable Variation Parameters:

• ESR: Equal or lower values are acceptable
• Lifetime @ Temperature: Equal or higher values are acceptable
• Ripple Current @ High Frequency: Equal or higher values are acceptable
• Height - Seated: Equal or lower values are acceptable (PCB clearance consideration)

The substitute part EEF-CX0J101R meets all mandatory matching criteria and demonstrates improvements in lifetime rating and ripple current capacity, making it a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The EEF-CX0J101R from Panasonic Electronic Components is a direct functional equivalent to the obsolete ESRH101M06R. Both components are ROHS3 compliant and operate across the identical temperature range. The substitute part offers enhanced performance characteristics: doubled lifetime rating (2000 hours versus 1000 hours at 105°C) and doubled ripple current capacity (5.1 A versus 2.5 A at 100 kHz). The substitute also features reduced seated height (1.90 mm versus 2.80 mm), providing additional PCB layout flexibility.

The EEF-CX0J101R maintains active product status with established supply chain availability, eliminating procurement risk associated with the obsolete ESRH101M06R. All electrical and mechanical parameters align with the original specification, ensuring direct board-level compatibility without design modification.

Frequently Asked Questions (FAQ)

Q: Can the EEF-CX0J101R be used as a direct replacement for the ESRH101M06R without PCB modification?

A: Yes. Both components share identical capacitance (100 µF), voltage rating (6.3 V), package designation (2917 / 7343 Metric), surface mount land size (7.30 mm × 4.30 mm), and ESR (15 mOhm). No PCB layout changes are required for electrical or mechanical compatibility.

Q: What is the significance of the improved lifetime rating in the substitute part?

A: The EEF-CX0J101R provides 2000 hours at 105°C compared to 1000 hours for the ESRH101M06R. This parameter indicates extended operational reliability under thermal stress. The substitute part delivers twice the rated service life under identical temperature conditions.

Q: Does the reduced height of the EEF-CX0J101R affect compatibility?

A: No. The substitute part height (1.90 mm seated maximum) is lower than the original (2.80 mm seated maximum). This reduction provides additional clearance margin and does not create compatibility issues. PCB footprints and solder land patterns remain identical.

Q: Are both components compliant with current environmental regulations?

A: Yes. Both the ESRH101M06R and EEF-CX0J101R are ROHS3 compliant. The substitute part additionally carries REACH Unaffected status, confirming compliance with European chemical regulations.

Q: What is the significance of the increased ripple current rating?

A: The EEF-CX0J101R supports 5.1 A ripple current at 100 kHz, compared to 2.5 A for the ESRH101M06R. This parameter indicates the substitute part can dissipate higher AC current without exceeding temperature limits. Applications with elevated ripple current demands benefit from this enhanced specification.

Q: Is the substitute part available in the same packaging format?

A: The EEF-CX0J101R is supplied in Tape & Reel (TR) format, suitable for automated assembly processes. The ESRH101M06R packaging format was not specified in the original data. Both components use identical surface mount package designation (2917 / 7343 Metric).
