Substitute Part Grouping Explanation

Substitution eligibility for the RSMF2JB20R0 is determined by strict equivalence in the following parameters:

• Resistance value: 20 Ohms
• Tolerance: ±5%
• Power rating: 2W
• Composition: Metal Oxide Film
• Package configuration: Axial through hole
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C ~ 235°C
• Regulatory compliance: ROHS3 Compliant, REACH Unaffected

The RSF2JT20R0 meets all electrical and mechanical substitution criteria. Differences in physical dimensions and packaging format (bulk versus cut tape) do not affect functional equivalence in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both RSMF2JB20R0 and RSF2JT20R0 are active production parts from Stackpole Electronics Inc with identical electrical specifications and regulatory compliance. Selection between these parts is based on packaging and inventory requirements. The RSMF2JB20R0 is supplied in bulk packaging, while the RSF2JT20R0 is available in cut tape format. Both parts maintain ROHS3 compliance and REACH unaffected status, making them suitable for applications with regulatory requirements. The choice between these substitutes depends on procurement workflow and assembly process compatibility rather than electrical performance.

Frequently Asked Questions (FAQ)

Q: Can RSF2JT20R0 replace RSMF2JB20R0 in existing designs? A: Yes. Both parts share identical electrical specifications: 20 Ohms resistance, ±5% tolerance, 2W power rating, metal oxide film composition, and operating temperature range of -55°C to 235°C. Functional equivalence is maintained across all circuit applications.

Q: What is the difference between these two part numbers? A: The primary differences are packaging format and physical dimensions. RSMF2JB20R0 is supplied in bulk packaging with dimensions of 0.177" diameter × 0.433" length. RSF2JT20R0 is supplied in cut tape format with dimensions of 0.217" diameter × 0.591" length. These dimensional variations do not affect electrical performance or circuit compatibility.

Q: Are both parts compliant with current regulations? A: Yes. Both RSMF2JB20R0 and RSF2JT20R0 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components.

Q: Which part should I select for new designs? A: Selection should be based on your assembly process requirements. If your production line uses cut tape feeding systems, RSF2JT20R0 is appropriate. If bulk component handling is used, RSMF2JB20R0 is suitable. Electrical performance is identical between both options.
