Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RSMF2JB22R0 is determined by strict equivalence across the following critical parameters:

• Resistance value: 22 Ohms
• Tolerance: ±5%
• Power dissipation: 2W
• Composition: Metal Oxide Film
• Package configuration: Axial through hole
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C to 235°C
• Regulatory compliance: ROHS3 Compliant

The RSF2JT22R0 meets all electrical and mechanical substitution criteria. Both parts share identical resistance, tolerance, power rating, composition, and thermal specifications. The primary difference is packaging format (bulk versus cut tape) and physical dimensions, which do not affect electrical performance or circuit compatibility in axial through hole applications.

Parameter Comparison

Engineering Selection Recommendations

Both the RSMF2JB22R0 and RSF2JT22R0 are active production parts from Stackpole Electronics Inc with full ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on packaging requirements and supply chain considerations. The RSMF2JB22R0 is supplied in bulk packaging, while the RSF2JT22R0 is available in cut tape format. Both parts maintain identical electrical performance and thermal characteristics across the specified operating range of -55°C to 235°C. The choice between these substitutes does not impact circuit functionality or reliability when used in equivalent axial through hole applications.

Frequently Asked Questions (FAQ)
