Frequently Asked Questions (FAQ)

Q: Can the MMF404326 be used as a direct replacement for the MMF003133?

A: Yes. The MMF404326 is electrically and mechanically identical to the MMF003133 across all specified parameters, including resistance value, tolerance, strain range, active dimensions, overall dimensions, and operating temperature range. Both components are manufactured by Micro-Measurements in the CEA series.

Q: What is the difference between RoHS Compliant and ROHS3 Compliant?

A: ROHS3 Compliant represents the current RoHS 3 directive standard, which supersedes earlier RoHS compliance classifications. The MMF404326 meets the more recent regulatory requirement. Both certifications confirm restriction of hazardous substances in the component.

Q: Why is the MMF003133 listed as Obsolete?

A: Obsolete status indicates the component is no longer in active production by the manufacturer. The MMF404326 is the current production equivalent, ensuring access to ongoing manufacturing support and supply chain continuity.

Q: Are the active dimensions identical between both parts?

A: Yes. Both the MMF003133 and MMF404326 have active dimensions of 0.125" (3.18mm) length by 0.100" (2.54mm) width. Overall dimensions are also identical at 0.38" (9.7mm) length by 0.19" (4.8mm) width.

Q: What is the significance of MSL 1 (Unlimited)?

A: Moisture Sensitivity Level 1 (Unlimited) indicates the component has no moisture sensitivity restrictions. Storage and handling do not require controlled humidity environments or desiccant packaging.

Q: Is the operating temperature range the same for both parts?

A: Yes. Both the MMF003133 and MMF404326 operate across the identical temperature range of -100 ~ 350°F (-75 ~ 175°C).

Q: What packaging is available for the MMF404326?

A: The MMF404326 is supplied in Bulk packaging. Specific packaging quantities should be confirmed with the supplier based on procurement requirements.
