MMF003204 Equivalent & Substitute Parts

Part Overview

The MMF003204 is a linear strain gauge manufactured by Micro-Measurements (Division of Vishay Precision Group), part of the CEA series. This component features 350 Ohms resistance with ±5% strain range capability and is designed for precision measurement applications requiring active gauge dimensions of 0.250" × 0.120" (6.35mm × 3.05mm).

The MMF003204 is classified as obsolete. Locating equivalent or substitute components is necessary to support ongoing maintenance, repair, and new design requirements where this gauge specification remains applicable.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MMF003204 is based on the following critical parameters that must align between the main part and substitute:

Primary Substitution Criteria:

• Manufacturer: Micro-Measurements (Division of Vishay Precision Group)
• Series: CEA
• Pattern Type: Linear
• Resistance: 350 Ohms
• Moisture Sensitivity Level: 1 (Unlimited)
• ECCN Classification: EAR99
• HTSUS Code: 9031.80.8085

The MMF404864 qualifies as a manufacturer-recommended substitute because it maintains the same manufacturer, series designation, pattern type, resistance value, and regulatory classifications. The substitute part is classified as active product status, ensuring ongoing availability and support.

Parameter Comparison

Engineering Selection Recommendations

The MMF404864 is the manufacturer-recommended substitute for the obsolete MMF003204. Both components share identical core electrical specifications (350 Ohms resistance, linear pattern type, CEA series designation) and regulatory classifications (EAR99, HTSUS 9031.80.8085).

The substitute part offers the advantage of active product status, ensuring continued manufacturing support and availability. The MMF404864 maintains MSL Level 1 (Unlimited) moisture sensitivity classification, consistent with the original part.

The upgrade from RoHS Compliant to ROHS3 Compliant status in the substitute part reflects current regulatory standards and provides enhanced environmental compliance documentation.

Frequently Asked Questions (FAQ)

Q: Can MMF404864 directly replace MMF003204 in existing applications?

A: The MMF404864 maintains the same resistance value (350 Ohms), pattern type (linear), series designation (CEA), and moisture sensitivity level as the MMF003204. Both components are manufactured by Micro-Measurements and share identical regulatory classifications. The substitute is classified as the manufacturer-recommended equivalent.

Q: What is the difference in product status between these parts?

A: The MMF003204 is classified as obsolete, indicating discontinued manufacturing. The MMF404864 is classified as active, meaning it is currently manufactured and supported by Micro-Measurements. This transition ensures continued availability for applications requiring 350 Ohm linear strain gauges in the CEA series.

Q: Are there differences in packaging between MMF003204 and MMF404864?

A: The MMF003204 is supplied in standard packaging. The MMF404864 is supplied in box packaging. Both maintain identical MSL Level 1 (Unlimited) moisture sensitivity classification, indicating no special moisture protection requirements during storage or handling.

Q: Do both parts meet current environmental compliance standards?

A: The MMF003204 carries RoHS Compliant certification. The MMF404864 carries ROHS3 Compliant certification, reflecting the current regulatory standard. Both parts are classified as EAR99 for export control purposes and share the same HTSUS code (9031.80.8085).

Q: What parameters must remain constant when substituting these strain gauges?

A: Critical parameters that must align are: manufacturer (Micro-Measurements), series (CEA), pattern type (linear), and resistance value (350 Ohms). These parameters define the functional equivalence between the MMF003204 and MMF404864.
