Hello,
Multiple part number are listed for LM158QML-SP:
https://www.ti.com/product/LM158QML-SP?keyMatch=LM158QML-SP#order-quality
1. Are the all parts in the link above the space-grade certified?
2. If you look at the CFP package products, there are LM158AWGRLQMLV and LM158AWGRQMLV. What is the difference between the two products?
3. Are the two products shown below exactly the same product?
Thank you.
JH
Hey JH,
The SMD document on the product page answers all of these questions. If you are working on a VPN (like I was) it will not let you open it.
Here are additional helpful resources for interpreting the space part numbers:
FAQ on RHA and DLA SMD
1002 variants:
| TI Standard Part # | DLA SMD | Package |
LM158AHRQMLV |
5962R8771002VGA |
TO-99 (LMC) | 8 |
LM158AJRQMLV |
5962R8771002VPA |
CDIP (NAB) | 8 |
LM158AWGRQMLV |

CFP (NAC) | 10 |
1003 variants
| TI Standard Part # | DLA SMA | Package |
LM158AHRLQMLV |
5962R8771003VGA |
TO-99 (LMC) | 8 |
LM158AJRLQMLV |
5962R8771003VPA |
CDIP (NAB) | 8 |

Looking at the DLA SMD resource:
To answer your questions:
1. Are the all parts in the link above the space-grade certified? Quoting the earlier linked FAQ
"All QML devices start with 5962. However, the key differentiator for an RHA device is to have a letter following the 5962 number. This letter distinguishes the TID level that the product has been qualified for. "
2. If you look at the CFP package products, there are LM158AWGRLQMLV and LM158AWGRQMLV. What is the difference between the two products?
LM158AWGRLQMLV |
5962R8771003VXA |
LM158AWGRQMLV |
5962R8771002VXA |
I have highlighted the differences in red, looking at the SMD document, the highlighted difference is the "Device Type"
Device Type 3 seems to have more features which explains the price discrepancy.
3. Are the two products shown below exactly the same product?
Yes, as highlighted in the initial table and on the webpage. One is the TI standard part name and the other is the DLA SMD.
All the best,
Carolina
Hey JH,
If the customer wants to receive a space-grade part that has been radiation tested they may order all of these parts.
| TI Standard Part # | DLA SMD |
LM158AHRQMLV |
5962R8771002VGA |
LM158AJRQMLV |
5962R8771002VPA |
LM158AWGRQMLV |
5962R8771002VXA |
LM158AHRLQMLV |
5962R8771003VGA |
LM158AJRLQMLV |
5962R8771003VPA |
LM158AWGRLQMLV |
5962R8771003VXA |
Perhaps I was not clear enough in my description. The DLA SMD part and the TI standard # are the same and may be ordered interchangeably.
The DLA SMD number makes for an easy comparison:
Looking at the table above I have split the part numbers:

I am referencing this resource: https://landandmaritimeapps.dla.mil/Downloads/MilSpec/Smd/87710.pdf and this resource: DLA SMD
All of the above parts have been radiation hardness assured to 1x10^5 Rads (Si)
Differences in device type:
02 LM158A Low power, dual operational amplifier
03 LM158A Low dose rate radiation hardened low power, dual operational amplifier
All of the above parts are device class V: Certification and qualification to MIL-PRF-38535
The case outline(s) are as designated in MIL-STD-1835 and as follows:
G MACY1-X8 8 Can
P GDIP1-T8 or CDIP2-T8 8 Dual-in-line
X GDFP1-G10 10 Flat pack with gull wing leads
And all the above devices have a hot solder dip finish:
Therefore as to your question:
It seems that if a customer wants to receive a space-grade part that has been performed radiation testing, they must order it with DLA SMD not TI standard PN. Is it correct?
This is incorrect. If a customer wants to receive a space grade part, they may order all of these parts.
All the best,
Carolina
