Key Parameters

Substitute Part Grouping Explanation

Substitution of the SCMZ1EP1F6STAB2 is determined by the following critical parameters:

Electrical Compatibility Criteria:

• Capacitance value within the tolerance band of the original part (165 F ±10%/+30% = 148.5 F to 214.5 F)
• Rated voltage equal to or greater than 48 V
• ESR value at or below the original specification to maintain performance characteristics
• Lifetime rating at 65°C sufficient for application requirements

Physical and Mechanical Criteria:

• Module form factor package type
• Operating temperature range encompassing -40°C to 65°C
• Compliance certifications (RoHS3, REACH Unaffected, EAR99)

Termination Consideration:

• Substitute parts may employ different termination methods (screw terminals versus cable connectors) provided the electrical interface is compatible with system integration requirements

The XLR-48R6167-R from Eaton - Electronics Division meets these substitution criteria through equivalent capacitance (166 F), compatible voltage rating (48.6 V), superior ESR performance (5 mOhm), and extended lifetime rating (1500 Hrs @ 65°C).

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (SCMZ1EP1F6STAB2): The SCMZ1EP1F6STAB2 remains the specified component when cable and connector termination is a system requirement. This part is Active in product status, ROHS3 compliant, and maintains full regulatory compliance under REACH and EAR99 classifications.

Substitute Part Selection (XLR-48R6167-R): The XLR-48R6167-R from Eaton - Electronics Division is a qualified substitute when screw terminal termination is compatible with system integration. This part offers electrical advantages including lower ESR (5 mOhm versus 5.22 mOhm), higher voltage rating (48.6 V versus 48 V), and extended thermal lifetime (1500 Hrs @ 65°C versus 1000 Hrs @ 65°C). Both parts maintain identical operating temperature ranges and regulatory compliance status.

Selection between these parts depends on termination method compatibility and system integration requirements rather than electrical performance, as the Eaton substitute provides equivalent or superior electrical characteristics.

Frequently Asked Questions (FAQ)

Q: Can the XLR-48R6167-R directly replace the SCMZ1EP1F6STAB2 in existing designs?

A: Electrical substitution is valid based on capacitance, voltage, and ESR parameters. However, the termination method differs (screw terminals versus cable connector). Direct mechanical replacement requires verification that the system integration can accommodate screw terminal connections in place of the cable connector interface.

Q: What is the capacitance tolerance impact on substitution?

A: The SCMZ1EP1F6STAB2 specifies -10%, +30% tolerance (148.5 F to 214.5 F range). The XLR-48R6167-R specifies 0%, +20% tolerance (166 F to 199.2 F range). The substitute part's tighter tolerance ensures more consistent capacitance values within a narrower band, which may improve system performance predictability.

Q: Does the lower ESR of the substitute part affect compatibility?

A: Lower ESR (5 mOhm versus 5.22 mOhm) is a performance advantage. The substitute part exhibits 4.2% lower resistance, which reduces heat generation and improves charge/discharge efficiency. This does not create compatibility issues; it represents improved electrical performance.

Q: Is the higher voltage rating of the substitute part a concern?

A: No. The XLR-48R6167-R is rated for 48.6 V, which is 1.25% higher than the 48 V specification of the primary part. A higher voltage rating does not create compatibility issues when operating at or below the original voltage specification.

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

A: The XLR-48R6167-R provides 1500 hours of operational life at 65°C compared to 1000 hours for the SCMZ1EP1F6STAB2. This 50% extension in thermal lifetime indicates improved long-term reliability under elevated temperature conditions, which may be advantageous for applications with extended operational requirements.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the SCMZ1EP1F6STAB2 and XLR-48R6167-R are ROHS3 compliant, REACH unaffected, and classified under EAR99. Both parts meet current regulatory requirements for electronic component distribution and use.

Q: What is the primary factor determining which part to select?

A: The termination method is the primary selection factor. Choose the SCMZ1EP1F6STAB2 when cable and connector termination is required. Choose the XLR-48R6167-R when screw terminal termination is compatible with system integration. Electrical performance favors the Eaton substitute, but termination compatibility drives the final selection.
