JZP-SC and JZP-SC1 have the same nominal overall height and mounting dimension. Their h dimensions are different: 24.5 mm for JZP-SC and 21.7 mm for JZP-SC1.
For equipment with fixed mounting brackets, this 2.8 mm difference needs to be checked before selecting a replacement.
The dimensional specifications for the two series are listed below.

JZP-SC has an h dimension 2.8 mm greater than JZP-SC1. Both series have the same specified H and A dimensions, but their dimensional drawings are not identical.
Check where h is measured on each drawing. The reference points must correspond to the same structural features before the two values can be compared for installation purposes.

The effect of the 2.8 mm difference depends on the mounting arrangement. For an existing installation, check the following items.

Inspection Item |
What to Check |
Possible Issue |
|
Mounting position |
Reference surfaces and h dimension |
Difference in mounting position |
|
Connection details |
Hole positions, thread specifications and effective thread depth |
Fastener mismatch or assembly interference |
|
Installation clearance |
Space around the isolator and mounting bracket |
Insufficient clearance |
|
Load conditions |
Equipment weight and load at each mounting point |
Unsuitable load distribution |
Consider a vibration isolator installed inside a control cabinet. The isolator may be positioned between a fixed support bracket and the equipment base. If the h dimension affects the position of a connecting surface, the replacement model may require additional clearance or a mounting adjustment.
The same check applies to other equipment with fixed mounting points. Compare the original and replacement drawings, paying attention to the contact surfaces and connection locations.
For equipment supported by several isolators, verify the load carried at each mounting point. The replacement must also meet the application's load and vibration requirements.
A CAD drawing comparison can help identify differences in mounting geometry before the replacement is ordered.
When requesting a JZP-SC or JZP-SC1 replacement, please provide:
Complete model number of the existing isolator
Original product drawing or CAD/DWG file
Equipment weight and load per mounting point
Mounting direction and available installation space
Photos of the existing isolator and its installed position
Required quantity and operating conditions
For equipment already in service, installation photographs are useful when the original drawing is unavailable. They can show the mounting arrangement, nearby components and available working space.
If you need to replace an existing JZP-SC or JZP-SC1 isolator, send us the model number and mounting drawing.
Xi'an Hoan Microwave Co., Ltd. can review the available dimensional information and check the mounting details against your application requirements.
Please include the equipment weight, required quantity and installation conditions with your inquiry.
