Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SPA271M0ER is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance value: 270 µF (exact match required)
• Voltage rating: 2.5 V (exact match required)
• Tolerance: ±20% (exact match required)
• ESR: 7 mOhm (exact match required)
• Type: Aluminum - Polymer (exact match required)

Mechanical Parameters:

• Package / Case: 2917 (7343 Metric) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Physical dimensions: 0.287" L x 0.169" W (7.30mm x 4.30mm) (exact match required)

Compliance Parameters:

• RoHS3 Compliance (required for regulatory alignment)

Substitute parts must satisfy all electrical, mechanical, and compliance criteria simultaneously. The EEF-SX0E271E7 meets these requirements and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The EEF-SX0E271E7 qualifies as a direct electrical and mechanical substitute for the SPA271M0ER based on identical capacitance, voltage rating, tolerance, ESR, package type, and mounting configuration. Both components maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements.

The substitute part offers enhanced performance characteristics: extended lifetime rating (2000 Hrs @ 105°C versus 1000 Hrs), expanded operating temperature range (-55°C to 105°C versus -40°C to 105°C), and increased ripple current capacity (7 A @ 100 kHz versus 3.5 A @ 100 kHz). The EEF-SX0E271E7 exhibits a reduced seated height (0.079" versus 0.110"), which provides additional design flexibility for space-constrained applications.

The substitute part maintains active product status with confirmed inventory availability, ensuring reliable procurement for ongoing production and future requirements.

Frequently Asked Questions (FAQ)

Q: Can the EEF-SX0E271E7 be used as a direct replacement for the SPA271M0ER in existing designs?

A: Yes. The EEF-SX0E271E7 meets all critical electrical and mechanical specifications: identical capacitance (270 µF), voltage rating (2.5 V), tolerance (±20%), ESR (7 mOhm), package type (2917 / 7343 Metric), and mounting configuration (surface mount). Physical footprint dimensions are identical, enabling direct PCB compatibility without layout modifications.

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

A: The primary differences are manufacturer origin, product status, and performance enhancements. The SPA271M0ER is obsolete; the EEF-SX0E271E7 is active. The substitute offers doubled lifetime rating (2000 Hrs versus 1000 Hrs @ 105°C), extended low-temperature operating range (-55°C versus -40°C minimum), doubled ripple current capacity (7 A versus 3.5 A @ 100 kHz), and reduced seated height (0.079" versus 0.110").

Q: Are there any height clearance concerns when substituting the EEF-SX0E271E7?

A: No. The substitute part has a lower seated height (0.079" maximum versus 0.110" maximum), providing improved clearance margins. This reduction eliminates potential height-related compatibility issues and may benefit designs with tight vertical spacing constraints.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both the SPA271M0ER and EEF-SX0E271E7 are ROHS3 compliant and REACH unaffected, satisfying equivalent regulatory requirements for environmental and hazardous substance restrictions.

Q: Why is the EEF-SX0E271E7 recommended over the obsolete SPA271M0ER?

A: The EEF-SX0E271E7 is recommended because it maintains active product status with confirmed inventory availability, ensuring uninterrupted supply chain access. It provides superior performance specifications while maintaining full electrical and mechanical compatibility, reducing design risk and supporting long-term production sustainability.
