Key Parameters

Substitute Part Grouping Explanation

Substitution of the MMF003101 strain gauge is determined by the following critical parameters that must remain consistent across equivalent components:

Primary Substitution Criteria:

• Resistance value: 350 Ohms
• Resistance tolerance: ±0.3%
• Pattern type: Linear
• Strain range: ±3%
• Active dimensions: 0.062" length × 0.120" width (1.57mm × 3.05mm)
• Series compatibility: CEA series

Secondary Compliance Criteria:

• RoHS compliance status
• Moisture sensitivity level (MSL 1)
• Operating temperature range: -100 ~ 350°F (-75 ~ 175°C)

The MMF404018 is identified as the manufacturer-recommended substitute. Both components share identical electrical specifications (350 Ohm resistance, ±3% strain range) and mechanical dimensions (active gauge area). Both maintain RoHS compliance and MSL 1 rating. The primary distinction is product status: MMF003101 is obsolete while MMF404018 is active, making MMF404018 the appropriate selection for new applications and ongoing inventory requirements.

Engineering Selection Recommendations

The MMF404018 is the manufacturer-recommended equivalent for the obsolete MMF003101 strain gauge. Selection of MMF404018 is appropriate based on the following factors:

Product Status Alignment: MMF003101 is classified as obsolete, creating supply chain constraints for new procurement. MMF404018 maintains active product status with confirmed inventory availability (670 Pcs New Original In Stock), ensuring reliable sourcing for current and future applications.

Compliance Continuity: Both components maintain identical RoHS compliance status and MSL 1 rating, ensuring regulatory and environmental requirements are preserved across the substitution.

Manufacturer Designation: The substitution is explicitly identified by Micro-Measurements as the manufacturer-recommended alternative, confirming engineering validation of functional equivalence.

Series Consistency: Both components belong to the CEA series, maintaining design lineage and established application compatibility within existing strain measurement systems.

For applications currently utilizing MMF003101, transition to MMF404018 is supported by the manufacturer's explicit substitution designation and maintained compliance certifications.

Frequently Asked Questions (FAQ)

Q: Why is MMF003101 being replaced?

A: MMF003101 is classified as obsolete by the manufacturer. MMF404018 is the active equivalent that maintains identical electrical and mechanical specifications while ensuring ongoing availability and supply chain continuity.

Q: Are the electrical specifications identical between MMF003101 and MMF404018?

A: Both components are specified as CEA series linear strain gauges. The manufacturer identifies MMF404018 as the direct substitute, confirming functional equivalence for the primary application parameters.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by: resistance value (350 Ohms), resistance tolerance (±0.3%), pattern type (linear), strain range (±3%), active dimensions (0.062" × 0.120"), and series designation (CEA). Both components meet these criteria.

Q: Are there packaging differences between these parts?
