Engineering Selection Recommendations

UCE-5/20-D48NB-C is classified as Obsolete, whereas UEE-5/30-D48NB-C is Active. Both parts are listed with MSL 1 (Unlimited) and REACH unaffected status, which aligns with standard compliance for this category. UEE-5/30-D48NB-C is ROHS3 compliant, while no ROHS status is specified for UCE-5/20-D48NB-C. Substitute selection is governed by the provided product status and compliance fields.

Frequently Asked Questions (FAQ)

Q: What parameters determine whether UEE-5/30-D48NB-C is a valid substitute for UCE-5/20-D48NB-C?
A: Permitted substitution is based strictly on matching input voltage range, output voltage, output current (equal or higher), output power, isolation voltage, operating temperature, mounting type, package/case, MSL, and product category.

Q: Is the packaging or mounting type consistent between UCE-5/20-D48NB-C and UEE-5/30-D48NB-C?
A: Both parts use through hole mounting and the 8-DIP Module, 1/8 Brick package/case.

Q: Are there any size or dimensional differences to consider?
A: UCE-5/20-D48NB-C has a height of 0.37" (9.4mm), while UEE-5/30-D48NB-C has a height of 0.50" (12.7mm). Length and width are identical.

Q: Does UEE-5/30-D48NB-C provide the same or greater electrical capability?
A: UEE-5/30-D48NB-C provides the same input voltage range and output voltage, with greater maximum output current and power.

Q: How do compliance and product status affect part selection?
A: UEE-5/30-D48NB-C is Active and ROHS3 compliant, suitable for use where active status and compliance with current environmental standards are required.
