Substitute Part Grouping Explanation

Substitution of the 4SXB150M is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 150 µF (exact match required)
• Voltage Rating: 4 V (exact match required)
• Tolerance: ±20% (exact match required)
• Package / Case: 2917 (7343 Metric) (exact match required for PCB compatibility)
• Mounting Type: Surface Mount (exact match required)
• Operating Temperature Range: -55°C ~ 105°C (exact match required)
• Lifetime @ Temperature: 2000 Hrs @ 105°C (exact match required)

The substitute part EEF-CX0G151R from Panasonic Electronic Components meets all critical electrical and mechanical parameters. While the ESR specification differs slightly (15 mOhm versus 13 mOhm) and ripple current capability is higher (5.1 A versus 3 A), these variations remain within acceptable engineering tolerances for general purpose applications and do not compromise functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

The EEF-CX0G151R from Panasonic Electronic Components is a direct functional equivalent to the obsolete 4SXB150M. Both components maintain identical electrical specifications for capacitance, voltage rating, tolerance, and operating temperature range. Both are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

The primary advantage of selecting the EEF-CX0G151R is its active product status, ensuring long-term availability and supply chain continuity. The substitute part's slightly higher ESR (15 mOhm versus 13 mOhm) and superior ripple current capability (5.1 A versus 3 A) present no compatibility concerns for general purpose applications and may provide improved performance margins in ripple-current-sensitive circuits.

Frequently Asked Questions (FAQ)

Q: Can the EEF-CX0G151R be used as a direct replacement for the 4SXB150M on existing PCBs?

A: Yes. Both components share identical package dimensions (2917 / 7343 Metric), surface mount land sizes, and seated heights. No PCB layout modifications are required.

Q: What is the significance of the ESR difference between the two parts?

A: The 4SXB150M specifies 13 mOhm ESR while the EEF-CX0G151R specifies 15 mOhm ESR. This 2 mOhm difference is negligible for general purpose applications and falls within normal manufacturing tolerances for aluminum polymer capacitors.

Q: Why does the substitute part have higher ripple current capability?

A: The EEF-CX0G151R is rated for 5.1 A ripple current at 100 kHz compared to the 4SXB150M's 3 A rating. This represents an enhancement in the substitute part's design and provides additional performance margin without affecting compatibility.

Q: Are there any compliance or certification differences?

A: Both parts are ROHS3 compliant and REACH unaffected. No compliance barriers exist to substitution.

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

A: The 4SXB150M is supplied in standard packaging, while the EEF-CX0G151R is available in Tape & Reel (TR) format. Tape & Reel packaging is standard for high-volume surface mount assembly and does not affect component functionality.
