Substitute Part Grouping Explanation

Substitution of the MMF003366 is determined by strict equivalence across the following critical parameters:

  • Resistance Value: 350 Ohms (exact match required)
  • Resistance Tolerance: ±0.4% (electrical specification match)
  • Pattern Type: Linear Weldable (functional form factor)
  • Strain Range: 0.5% (±5000µm/m) (measurement capability)
  • Active Dimensions: 0.250" × 0.125" (6.35mm × 3.18mm) (physical compatibility)
  • Operating Temperature Range: -320 ~ 500°F (-195 ~ 260°C) (environmental specification)
  • Moisture Sensitivity Level: 1 (Unlimited) (storage and handling classification)

The substitute part MMF500995 maintains electrical and mechanical equivalence across all specified parameters, enabling direct functional replacement in applications previously utilizing the MMF003366.

Engineering Selection Recommendations

Primary Substitute: MMF500995

The MMF500995 is the manufacturer-recommended substitute for the obsolete MMF003366. Both components are manufactured by the same organization (Micro-Measurements / VPG Micro-Measurements) and share identical 350 Ohm resistance specifications and RoHS non-compliance status. The MMF500995 maintains active product status, ensuring availability and continued manufacturer support.

Selection of MMF500995 is appropriate for:

  • Direct replacement in existing applications utilizing MMF003366
  • New designs requiring 350 Ohm linear weldable strain gauge technology
  • Applications operating within the -320 ~ 500°F (-195 ~ 260°C) temperature range
  • Systems where RoHS non-compliance is acceptable or required by application specifications

The transition from obsolete MMF003366 to active MMF500995 eliminates supply chain risk and ensures access to current manufacturing processes and quality assurance protocols.

Frequently Asked Questions (FAQ)

Q: Can MMF500995 be used as a direct replacement for MMF003366?

A: Yes. MMF500995 is the manufacturer-recommended substitute and maintains electrical equivalence at 350 Ohms resistance with identical RoHS non-compliance status and moisture sensitivity classification.

Q: What is the primary reason for substitution?

A: MMF003366 is classified as obsolete. MMF500995 is an active product from the same manufacturer, providing continued availability and supply chain continuity.

Q: Are the physical dimensions identical between MMF003366 and MMF500995?

A: The MMF003366 active dimensions are specified as 0.250" × 0.125" (6.35mm × 3.18mm). Detailed dimensional specifications for MMF500995 are not provided in the available data. Verification of physical compatibility with mounting and installation requirements is necessary prior to implementation.

Q: Do both parts comply with RoHS regulations?

A: No. Both MMF003366 and MMF500995 are classified as RoHS non-compliant. Applications subject to RoHS compliance requirements must address this classification through appropriate exemptions or alternative component selection.
