S-817B58AMC-CXVT2G Linear Voltage Regulator Equivalent & Substitute Parts

Part Overview

The S-817B58AMC-CXVT2G is a linear voltage regulator IC from ABLIC Inc. designed for positive fixed output applications. This device delivers a fixed 5.8V output at 75mA maximum current in a compact SOT-23-5 surface mount package. The regulator operates across an input voltage range up to 10V with a maximum dropout voltage of 0.23V at 10mA, making it suitable for low-power applications requiring stable voltage regulation.

The S-817B58AMC-CXVT2G carries a "Not For New Designs" product status. Identifying equivalent substitute parts ensures design continuity and supply chain flexibility for existing applications or when component availability becomes constrained.

Substitute Part Grouping Explanation

Substitution eligibility for the S-817B58AMC-CXVT2G is determined by strict equivalence across the following critical parameters:

• Fixed output voltage of 5.8V
• Maximum output current of 75mA
• Maximum input voltage of 10V
• Dropout voltage specification of 0.23V @ 10mA
• Quiescent current of 2.5 µA
• SOT-23-5 package configuration
• Surface mount technology
• Operating temperature range of -40°C ~ 85°C
• ROHS3 compliance and REACH unaffected status

Parts meeting all these criteria are classified as parametric equivalents and may be substituted in applications designed for the S-817B58AMC-CXVT2G.

Parameter Comparison

Engineering Selection Recommendations

The S-817B58AMC-CXVT2U is a direct parametric equivalent to the S-817B58AMC-CXVT2G. Both devices share identical electrical specifications, package configuration, and compliance certifications. The primary distinction is product lifecycle status: the S-817B58AMC-CXVT2G is designated "Not For New Designs," while the S-817B58AMC-CXVT2U maintains "Active" status.

For applications currently using the S-817B58AMC-CXVT2G, the S-817B58AMC-CXVT2U provides a direct replacement without circuit modification or re-qualification. Both parts are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity ratings. The substitute part offers improved supply chain availability with 1023 units in stock compared to 662 units of the original part.

Frequently Asked Questions (FAQ)

Q: Can the S-817B58AMC-CXVT2U be used as a direct replacement for the S-817B58AMC-CXVT2G?

A: Yes. Both parts are parametric equivalents with identical output voltage, current rating, input voltage range, dropout voltage, quiescent current, package type, and operating temperature specifications. No circuit modifications are required.

Q: Are there any differences in compliance or certifications between these parts?

A: No. Both the S-817B58AMC-CXVT2G and S-817B58AMC-CXVT2U are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity levels (MSL 1 - Unlimited).

Q: What does "Not For New Designs" mean for the S-817B58AMC-CXVT2G?

A: This product status indicates the part is in mature or end-of-life phase and is not recommended for new design implementations. Existing applications may continue to use available inventory, but new designs should consider the S-817B58AMC-CXVT2U or other active alternatives.

Q: Are the package dimensions identical between these parts?

A: Yes. Both parts use the SOT-23-5 package configuration (SC-74A, SOT-753 designations), ensuring identical PCB footprint and mounting requirements.

Q: What is the significance of the different part number suffixes (CXVT2G vs. CXVT2U)?

A: The suffix variation indicates different product lifecycle or manufacturing batches within the S-817 series. The electrical and mechanical specifications remain identical; the suffix does not affect functional compatibility.
