Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RSF2JB220R is determined by matching the following critical parameters: resistance value (220 Ohms), tolerance (±5%), power rating (2W or higher), composition (metal oxide film), temperature coefficient (±200ppm/°C), operating temperature range (-55°C ~ 235°C), axial package configuration, and regulatory compliance (ROHS3). Packaging format (bulk, tape & reel, or cut tape) does not affect electrical equivalence but influences procurement and assembly processes. Physical dimensions may vary within the axial form factor while maintaining functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

RSF2JT220R serves as a direct electrical equivalent to RSF2JB220R, differing only in packaging format (tape & reel versus bulk). Selection between these two is driven by assembly process requirements and procurement volume.

RSMF2JT220R is a manufacturer-recommended substitute offering identical electrical specifications with improved flame-proof safety features compared to the flame-retardant coating of the original part. Physical dimensions are reduced (4.50mm x 11.00mm versus 5.50mm x 15.00mm), which may require PCB layout verification. This part is supplied in tape & reel format.

RSMF3JT220R provides a performance upgrade with 3W power rating while maintaining all other electrical parameters. This higher power rating accommodates applications requiring additional thermal margin. The part is supplied in cut tape format with the highest inventory availability (6842 units). Selection of this upgrade is appropriate when circuit design permits the larger physical footprint or when enhanced power dissipation capability is beneficial.

All substitute parts maintain ROHS3 compliance and active production status, ensuring long-term availability and supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can RSF2JT220R replace RSF2JB220R directly? A: Yes. RSF2JT220R is electrically identical to RSF2JB220R. The only difference is packaging format: RSF2JT220R is supplied in tape & reel format while RSF2JB220R is supplied in bulk. Both are suitable for identical circuit applications.

Q: What is the difference between RSMF2JT220R and RSF2JB220R? A: RSMF2JT220R matches all electrical specifications of RSF2JB220R but features flame-proof safety design instead of flame-retardant coating. Physical dimensions are smaller (4.50mm x 11.00mm versus 5.50mm x 15.00mm). Verify PCB layout compatibility before substitution.

Q: When should RSMF3JT220R be selected instead of RSF2JB220R? A: RSMF3JT220R is selected when the application requires 3W power dissipation capability or when thermal margin enhancement is necessary. All other electrical parameters remain identical. Verify that the larger physical footprint accommodates the PCB layout.

Q: Are all substitute parts ROHS3 compliant? A: Yes. RSF2JT220R, RSMF2JT220R, and RSMF3JT220R are all ROHS3 compliant, matching the compliance status of RSF2JB220R.

Q: What packaging formats are available? A: RSF2JB220R is supplied in bulk format. RSF2JT220R and RSMF2JT220R are supplied in tape & reel format. RSMF3JT220R is supplied in cut tape format. Selection depends on assembly process requirements and volume.

Q: Do all parts operate across the same temperature range? A: Yes. RSF2JB220R, RSF2JT220R, RSMF2JT220R, and RSMF3JT220R all operate across -55°C to 235°C with ±200ppm/°C temperature coefficient.
