Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the VT243WFCR-ADJ is determined by the following criteria:

Primary Substitution Parameters:

• Base product number alignment (VT243 series)
• Manufacturer consistency (Analog Devices Inc./Maxim Integrated)
• Functional equivalence (Linear Voltage Regulator IC Output)
• Regulatory compliance matching (RoHS3, REACH Unaffected)
• Moisture sensitivity level compatibility (MSL 3)

The VT243WFCX-ADJ qualifies as a manufacturer-recommended substitute based on identical base product number, manufacturer origin, functional classification, and regulatory compliance status. The transition from obsolete to active product status enables continued component sourcing through standard distribution channels.

Parameter Comparison

Engineering Selection Recommendations

The VT243WFCX-ADJ is the manufacturer-recommended substitute for the obsolete VT243WFCR-ADJ. Both components maintain identical regulatory compliance certifications (ROHS3 Compliant, REACH Unaffected) and equivalent moisture sensitivity specifications (MSL 3, 168 Hours). The substitute part is currently in active production status with higher inventory availability, ensuring reliable long-term sourcing for new designs and replacement applications. Selection of the VT243WFCX-ADJ eliminates obsolescence risk while preserving functional and compliance equivalence.

Frequently Asked Questions (FAQ)

Q: What is the primary reason for substituting the VT243WFCR-ADJ? A: The VT243WFCR-ADJ is classified as obsolete. The VT243WFCX-ADJ is the active equivalent from the same manufacturer and base product series, ensuring continued component availability.

Q: Are the RoHS and REACH compliance statuses identical between the main part and substitute? A: Yes. Both the VT243WFCR-ADJ and VT243WFCX-ADJ are ROHS3 Compliant and REACH Unaffected, maintaining equivalent regulatory compliance.

Q: Is the moisture sensitivity level the same for both parts? A: Yes. Both components have an MSL rating of 3 (168 Hours), requiring identical handling and storage protocols.

Q: What is the difference between the part numbers VT243WFCR-ADJ and VT243WFCX-ADJ? A: The suffix designations (R vs. X) indicate packaging or manufacturing process variations within the VT243 base product series. Both are linear voltage regulator ICs from Analog Devices Inc./Maxim Integrated with equivalent functional specifications.

Q: Is inventory availability a factor in the substitution decision? A: Inventory levels reflect current stock status. The VT243WFCX-ADJ has higher availability (2515 Pcs) compared to the obsolete VT243WFCR-ADJ (639 Pcs), supporting long-term design continuity.
