Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RSMF2JB2K70 is determined by strict equivalence across the following critical parameters:

• Resistance value: 2.7 kOhms
• Tolerance: ±5%
• Power rating: 2W
• Composition: Metal Oxide Film
• Package configuration: Axial
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C to 235°C
• Physical dimensions: 0.177" Dia x 0.433" L (4.50mm x 11.00mm)
• Compliance certifications: ROHS3, REACH unaffected

The identified substitute part differs only in packaging format (Cut Tape versus Bulk), which does not affect electrical or mechanical performance. All other specifications remain identical.

Parameter Comparison

Engineering Selection Recommendations

Both RSMF2JB2K70 and RSMF2JT2K70 are functionally equivalent and interchangeable for all electrical and mechanical applications. Selection between these parts should be based on packaging requirements and supply chain logistics:

The RSMF2JB2K70 in Bulk packaging is suitable for high-volume manufacturing environments where components are processed through automated pick-and-place systems with bulk feeders.

The RSMF2JT2K70 in Cut Tape (CT) packaging is appropriate for applications requiring component-level traceability, smaller production runs, or integration with tape-fed assembly equipment.

Both parts maintain identical performance characteristics across the full operating temperature range of -55°C to 235°C and satisfy ROHS3 and REACH compliance requirements for regulated markets.

Frequently Asked Questions (FAQ)

Q: Can RSMF2JT2K70 be used as a direct replacement for RSMF2JB2K70?
