Substitute Part Grouping Explanation

The substitute part MMF405380 (EA-06-031MFA-120) is identified as the manufacturer-recommended equivalent for the obsolete MMF017660. The substitution is based on the following critical parameters that determine functional compatibility:

Key Substitution Criteria:

• Resistance value: 120 Ohms (maintained across both parts)
• Active gauge length: 0.031" (0.79mm) (identical specification)
• Active gauge width: 0.080" (2.03mm) (identical specification)
• Series designation: EA (consistent product line)
• RoHS compliance status: Both parts are RoHS compliant
• Moisture sensitivity level: Both rated MSL 1 (Unlimited)
• Gauge type: Linear strain gauge configuration

The substitute part MMF405380 is classified as an active product with 806 units in stock, providing long-term availability and supply chain continuity compared to the obsolete original part.

Parameter Comparison

Engineering Selection Recommendations

For New Designs and Production: Specify MMF405380 (EA-06-031MFA-120) as the primary component. This part is classified as active with confirmed manufacturer support and adequate inventory levels. The active product status ensures continued availability and technical documentation support from Micro-Measurements.

For Existing Systems Using MMF017660: The substitute part MMF405380 maintains electrical equivalence through identical resistance (120 Ohms) and critical dimensional parameters (0.031" active length, 0.080" active width). Both parts share identical RoHS compliance and MSL ratings, confirming compatibility in applications where these certifications are required.

Compliance Considerations: Both parts carry RoHS compliance certification and unlimited moisture sensitivity rating (MSL 1), suitable for standard industrial and commercial strain measurement applications. The ECCN classification (EAR99) applies to the original part; verify current export control status for the substitute part in your jurisdiction.

Frequently Asked Questions (FAQ)

Q: Can MMF405380 directly replace MMF017660 in existing applications? A: Yes. The substitute part maintains identical electrical resistance (120 Ohms) and critical active gauge dimensions (0.031" length × 0.080" width). Both parts are RoHS compliant with MSL 1 rating. Verify mechanical mounting compatibility based on overall dimensions provided for the substitute part.

Q: What is the primary reason for substitution? A: MMF017660 is classified as obsolete. MMF405380 is the manufacturer-recommended active equivalent, ensuring long-term supply chain continuity and ongoing technical support from Micro-Measurements.

Q: Are there differences in packaging between these parts? A: The substitute part MMF405380 is supplied in bag packaging. Confirm packaging requirements for your assembly and storage procedures.

Q: Do both parts meet the same compliance standards? A: Yes. Both MMF017660 and MMF405380 are RoHS compliant and rated MSL 1 (Unlimited moisture sensitivity). Both carry HTSUS classification 9031.80.8085 for tariff purposes.

Q: What are the critical parameters that must match for substitution? A: Resistance value (120 Ohms), active gauge length (0.031" / 0.79mm), and active gauge width (0.080" / 2.03mm) are the primary electrical and dimensional parameters that determine functional equivalence. Both parts maintain these specifications.

Q: Is inventory availability a consideration? A: Both parts are currently in stock. MMF017660 has 758 units available; MMF405380 has 806 units available. For long-term production planning, MMF405380 is recommended due to its active product status.
