Engineering Selection Recommendations

XG4A-5031 is the direct substitute for XG4A-5031-8. Selection of XG4A-5031 is based on the following engineering criteria:

Product Status: XG4A-5031 maintains Active status, ensuring continued manufacturing and supply availability. XG4A-5031-8, designated Last Time Buy, has limited remaining inventory and no future production.

Compliance & Certification: Both parts maintain identical RoHS3 compliance and UL94 V-0 flammability rating, satisfying regulatory requirements for equivalent applications.

Electrical & Mechanical Specifications: All critical parameters—connector type, position count, pitch, current rating, voltage rating, operating temperature range, contact materials, and termination method—are identical between the two parts.

Inventory Availability: XG4A-5031 has 2070 units in stock (Tray packaging), compared to 748 units of XG4A-5031-8. The substitute part provides superior supply chain continuity.

For new designs or long-term production requirements, XG4A-5031 is the appropriate selection. For existing designs currently using XG4A-5031-8, direct substitution with XG4A-5031 is electrically and mechanically valid.

Frequently Asked Questions (FAQ)

Q: Can XG4A-5031 be used as a direct replacement for XG4A-5031-8?
