Equivalent & Substitute Parts: MMF003672

Part Overview

The MMF003672 is a Tee Rosette Strain Gauge manufactured by Micro-Measurements (Division of Vishay Precision Group). This component is classified as obsolete, though 1070 pieces remain available in new original stock. The strain gauge operates within a ±3% strain range and features a 350 Ohm resistance specification. Due to its obsolete product status, identification of active equivalent parts is necessary for ongoing procurement and system continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MMF003672 is based on the following critical parameters that must align between the main part and substitute candidates:

Primary Substitution Criteria:

• Manufacturer: Micro-Measurements (Division of Vishay Precision Group)
• Resistance: 350 Ohms
• Series: CEA
• RoHS Compliance: RoHS Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The substitute part MMF404554 shares the core electrical specification (350 Ohm resistance) and maintains compliance with RoHS requirements and moisture sensitivity classification. Both parts originate from the same manufacturer and series, establishing functional equivalence for applications requiring 350 Ohm strain gauge elements.

Parameter Comparison

Engineering Selection Recommendations

The MMF404554 serves as the active equivalent to the obsolete MMF003672. Both components maintain identical electrical specifications (350 Ohm resistance) and comply with RoHS requirements and MSL classification. The primary distinction is product status: MMF003672 is obsolete while MMF404554 is active.

For new designs or long-term procurement requirements, MMF404554 is the appropriate selection due to its active product status and continued manufacturer support. Both parts are supplied by Micro-Measurements and carry equivalent compliance certifications (RoHS Compliant, MSL 1).

Frequently Asked Questions (FAQ)

Q: Can MMF404554 directly replace MMF003672 in existing applications?

A: Both parts share identical resistance specifications (350 Ohms) and originate from the same manufacturer series (CEA). Substitution is based on matching electrical and compliance parameters. Verify mechanical fit and pattern configuration requirements for your specific application.

Q: What is the significance of the obsolete status of MMF003672?

A: Obsolete status indicates that Micro-Measurements no longer manufactures this part. While 1070 pieces remain in new original stock, long-term availability is not guaranteed. MMF404554, classified as active, represents the current production equivalent.

Q: Are there differences in packaging between these parts?

A: MMF003672 packaging is not specified in available documentation. MMF404554 is supplied in Bulk packaging. Confirm packaging requirements for your procurement process.

Q: Do both parts meet the same compliance standards?

A: Both MMF003672 and MMF404554 are RoHS Compliant and carry MSL 1 (Unlimited) classification. Both share identical ECCN (EAR99) and HTSUS (9031.80.8085) codes.

Q: What parameters must match for substitution to be valid?

A: Critical matching parameters include resistance value (350 Ohms), manufacturer (Micro-Measurements), series (CEA), and compliance certifications (RoHS, MSL). Pattern type and dimensional specifications should be verified against application requirements.
