Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete MMF309393 is determined by alignment of the following critical parameters:

Primary Substitution Criteria:

• Manufacturer: Micro-Measurements (Division of Vishay Precision Group)
• Product Type: Strain Gauge
• RoHS Compliance: RoHS Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• Product Status: Active (required for ongoing procurement)

The MMF403993 qualifies as a manufacturer-recommended substitute based on identical manufacturer origin, matching RoHS compliance status, and equivalent moisture sensitivity classification. Both components maintain the same environmental and regulatory compliance profile, enabling direct substitution in applications where the obsolete MMF309393 was previously specified.

Parameter Comparison

Engineering Selection Recommendations

For New Designs and Procurement: Select MMF403993 as the primary component choice. This part maintains active product status with Micro-Measurements, ensuring continuous availability, technical support, and supply chain reliability. Active product status eliminates obsolescence risk and provides access to current manufacturing processes and quality assurance protocols.

For Existing Systems Using MMF309393: The MMF403993 substitute maintains equivalent RoHS compliance and moisture sensitivity classification, supporting direct substitution in applications currently utilizing the obsolete MMF309393. Both components share identical environmental compliance profiles and regulatory certifications.

Compliance Considerations: Both the main part and substitute are RoHS Compliant with MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage and handling. This equivalence in compliance status eliminates additional qualification requirements for substitution.

Frequently Asked Questions (FAQ)

Q: Can MMF403993 directly replace MMF309393 in existing applications?

A: Yes. Both components are manufactured by Micro-Measurements, maintain RoHS Compliance, and share identical Moisture Sensitivity Level (MSL 1 - Unlimited) classification. These aligned parameters support direct substitution in applications previously specified with MMF309393.

Q: Why is MMF309393 classified as obsolete?

A: MMF309393 has reached end-of-life status within Micro-Measurements' product portfolio. The active substitute MMF403993 represents the current generation equivalent, providing continued access to strain gauge technology with modern manufacturing and support infrastructure.

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

A: MSL 1 (Unlimited) indicates the component has no moisture sensitivity restrictions. Both the main part and substitute can be stored and handled without special moisture control measures, simplifying logistics and inventory management.

Q: Are there packaging differences between MMF309393 and MMF403993?

A: Packaging specifications are not provided in the available technical data for either component. Contact Micro-Measurements directly for detailed packaging and dimensional specifications if packaging compatibility is a critical requirement.

Q: What export classifications apply to these strain gauges?

A: MMF309393 is classified under ECCN EAR99 and HTSUS 9031.80.8085. Export classification data for MMF403993 is not included in the available technical documentation. Verify current export requirements with Micro-Measurements or your compliance department.

Q: Is inventory availability a factor in component selection?

A: Current inventory shows 768 units of MMF309393 and 705 units of MMF403993 in stock. For long-term procurement planning, MMF403993 is recommended due to active product status, which ensures continued manufacturing and restocking capability beyond current inventory levels.
