Key Parameters

Substitute Part Grouping Explanation

Substitution of the ESRH101M06B 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)
• Dielectric Type: Aluminum - Polymer (exact match required)
• Package / Case: 2917 (7343 Metric) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Tolerance: ±20% (exact match required)
• Operating Temperature Range: -55°C to 105°C (exact match required)

Allowable Parameter Variations:

• ESR: Equal to or lower than 15 mOhm
• Lifetime @ 105°C: Equal to or greater than 1000 hours
• Ripple Current @ 100 kHz: Equal to or greater than 2.5 A
• Physical dimensions: Within tolerance of specified land size and height
• RoHS and REACH compliance status

The substitute part EEF-CX0J101R meets all mandatory matching criteria and demonstrates improvements in lifetime rating and ripple current capacity, while maintaining identical electrical specifications for capacitance, voltage, ESR, and tolerance.

Parameter Comparison

Engineering Selection Recommendations

The EEF-CX0J101R from Panasonic Electronic Components is a direct functional equivalent to the obsolete ESRH101M06B. Selection of this substitute is based on the following engineering criteria:

Compliance and Certification: Both parts maintain ROHS3 compliance, satisfying regulatory requirements for hazardous substance restrictions. The EEF-CX0J101R additionally carries REACH Unaffected status, providing extended environmental compliance documentation.

Product Availability and Support: The ESRH101M06B is classified as obsolete, limiting long-term procurement viability. The EEF-CX0J101R maintains active product status with documented inventory availability (12,917 pieces), ensuring supply chain continuity for new designs and ongoing production support.

Electrical Performance: Both parts deliver identical electrical specifications across capacitance (100 µF), voltage rating (6.3 V), tolerance (±20%), and ESR (15 mOhm). The substitute part demonstrates enhanced performance characteristics: doubled lifetime rating (2000 hours versus 1000 hours at 105°C) and increased ripple current capacity (5.1 A versus 2.5 A at 100 kHz).

Physical Compatibility: The EEF-CX0J101R maintains identical footprint dimensions and land size specifications, enabling direct PCB layout compatibility. The reduced seated height (1.90 mm versus 2.80 mm) provides additional design flexibility for space-constrained applications without compromising electrical function.

Packaging Considerations: The substitute part is supplied in Tape & Reel (TR) packaging, standard for high-volume surface mount assembly operations. This packaging format aligns with modern manufacturing processes and automated placement equipment.

Frequently Asked Questions (FAQ)

Q: Can the EEF-CX0J101R be used as a direct replacement for the ESRH101M06B in existing designs?

A: Yes. The EEF-CX0J101R meets all mandatory electrical and mechanical specifications required for direct substitution. Identical capacitance (100 µF), voltage rating (6.3 V), tolerance (±20%), ESR (15 mOhm), package type (2917 / 7343 Metric), and operating temperature range (-55°C to 105°C) ensure functional equivalence. PCB footprint and land size specifications are identical, requiring no layout modifications.

Q: What are the key differences between these two parts?

A: The primary differences are product status and performance enhancements. The ESRH101M06B is obsolete; the EEF-CX0J101R is active. The substitute offers doubled thermal lifetime (2000 hours versus 1000 hours at 105°C) and significantly higher ripple current capacity (5.1 A versus 2.5 A at 100 kHz). The EEF-CX0J101R also features a lower seated height (1.90 mm versus 2.80 mm), providing design flexibility.

Q: Are there any compliance or certification differences?

A: Both parts are ROHS3 compliant. The EEF-CX0J101R carries additional REACH Unaffected certification, providing extended environmental compliance documentation for regulated markets.

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

A: No. The reduced seated height (1.90 mm versus 2.80 mm) is a design advantage. It maintains identical footprint and land size specifications, ensuring compatibility with existing PCB layouts while providing additional clearance for adjacent components or enclosure constraints.

Q: What packaging format is the substitute part supplied in?

A: The EEF-CX0J101R is supplied in Tape & Reel (TR) packaging, standard for automated surface mount assembly. This format is compatible with modern pick-and-place equipment and high-volume manufacturing processes.

Q: Are there any electrical performance trade-offs when substituting to the EEF-CX0J101R?

A: No trade-offs exist. The substitute part maintains identical electrical specifications (capacitance, voltage, tolerance, ESR) while delivering superior performance in thermal lifetime and ripple current capacity. This represents a performance upgrade with no electrical compromises.

Q: Can the EEF-CX0J101R be used in applications requiring the exact 1000-hour lifetime specification of the original part?

A: Yes. The EEF-CX0J101R exceeds the original 1000-hour requirement with a 2000-hour lifetime rating at 105°C, providing extended operational reliability and margin for demanding thermal environments.
