PART NUMBER STRUCTURE

Options and Adaptations

Optional Functions and Part Number Suffixes

The versatile UHE, 12-30W DC/DC converters offer numerous electrical and

mechanical options. Per the Ordering Guide on page 2, the trailing DXX or QXX

part number. Part-number suffixes are added after this input identification,

indicating the selection of standard options. The resulting part number is a

"standard product" and is available to any customer desiring that particular

combination of options.

The On/Off Control function on pin 4 employs a positive logic (on = open or

"high," no suffix). To request a negative logic on this pin/function, add an "N"

suffix to the part number. Standard models have no pins in the pins 5 and 8

these positions (see pinout P52) by adding an "R" suffix. An "NR" suffix can be

added for both negative-logic and sense-pin options. See below.

Suffix Description

Blank

no Sense pins, pin length 0.2 inches (5.08 mm).

N

Add Negative logic on the On/Off Control function, VOUT trim (pin 9),

no Sense pins.

R

only). Available under special order.

NR

models only). Available under special order.

Alternate pin lengths are available under special order

T

Alternate trim configuration. Special order only.

-C

Full RoHS-6 compliance.

-Y

RoHS-5 hazardous substance compliance with lead exception. RoHS-5

compliance requires a scheduled quantity order. Not all RoHS-5 “-Y”

models are available. Please contact Product Marketing for further

information.

Adaptations

There are various additional configurations available on UHE, 12-30W DC/DCs.

Because designating each of them with a standard part-number suffix is not

always feasible, such are designated by MPS in assigning a 5-digit “adaptation

code” after the part-number suffixes. Contact MPS directly if you are interested

in your own set of options/adaptations. Our policy for minimum order quantities

may apply. Consequently, the following products are offered for sale:

UHE-5/6000-D48N-30749

UHE-5/6000-D48N-30749-Y (RoHS-5)

function, modified Trim function (5% trim up = 9.09kΩ, 5% trim down =

3.83kΩ, compatible with UEP-30750), integrated soft start and with input OVP

and thermal shutdown removed.

RoHS-5 compliance refers to the exclusion of the six hazardous substances

in the RoHS specification with the excepion of lead. MPS’s RoHS-5 products

use all the conforming RoHS materials, however our solders contain lead.

UHE-3.3/7500-D48THL2-Y and

UHE-5/6000-D48THL2-Y (RoHS-5)

Special trim, conformal coating, 3.68mm pin length, positive on/off logic,

RoHS-5 hazardous substance compliance (with lead).
