RSF2JB12R0 Equivalent & Substitute Parts

Part Overview

The RSF2JB12R0 is a 12 Ohms ±5% 2W through-hole resistor manufactured by Stackpole Electronics Inc. This axial metal oxide film resistor features flame retardant coating and safety characteristics, designed for applications requiring reliable power dissipation in the 2-watt range. The part is currently active in production with ROHS3 compliance and REACH unaffected status. Substitute parts are identified to provide alternative sourcing options when the primary packaging format is unavailable or when inventory constraints require alternative distribution channels.

Substitute Part Grouping Explanation

The RSF2JT12R0 qualifies as a direct substitute for the RSF2JB12R0 based on identical electrical and mechanical parameters. Both parts share the same resistance value (12 Ohms), tolerance (±5%), power rating (2W), composition (metal oxide film), temperature coefficient (±200ppm/°C), operating temperature range (-55°C ~ 235°C), physical dimensions (0.217" Dia x 0.591" L), and regulatory compliance (ROHS3 Compliant, REACH Unaffected). The substitution is valid across all electrical and thermal performance criteria. The primary difference between these parts is packaging format: RSF2JB12R0 is supplied in Bulk packaging, while RSF2JT12R0 is supplied in Cut Tape (CT) packaging. Both are manufactured by Stackpole Electronics Inc within the RSF series and maintain active product status.

Parameter Comparison

Engineering Selection Recommendations

Both RSF2JB12R0 and RSF2JT12R0 are suitable for applications requiring a 12 Ohms 2W axial resistor with metal oxide film construction. Selection between these parts should be based on procurement and assembly requirements. The RSF2JB12R0 in bulk packaging is appropriate for high-volume applications with in-house tape preparation or direct bulk handling. The RSF2JT12R0 in cut tape packaging is suitable for automated pick-and-place assembly processes and applications requiring pre-formatted component delivery. Both parts maintain identical electrical performance, thermal characteristics, and regulatory compliance. The choice between packaging formats does not affect circuit performance or reliability.

Frequently Asked Questions (FAQ)

Q: Can RSF2JT12R0 replace RSF2JB12R0 in my circuit design? A: Yes. Both parts are electrically and mechanically identical with the same 12 Ohms resistance, ±5% tolerance, 2W power rating, and operating temperature range. The only difference is packaging format (bulk versus cut tape).

Q: What is the difference between bulk and cut tape packaging? A: Bulk packaging supplies loose components suitable for manual assembly or custom tape preparation. Cut tape packaging provides components pre-formatted on carrier tape for automated assembly equipment. Both formats contain the same component.

Q: Are both parts RoHS compliant? A: Yes. Both RSF2JB12R0 and RSF2JT12R0 are ROHS3 Compliant and REACH Unaffected.

Q: Can I use these resistors in high-temperature applications? A: Yes. Both parts operate across the temperature range -55°C ~ 235°C with a temperature coefficient of ±200ppm/°C, suitable for extended temperature applications within this range.

Q: Are the physical dimensions identical? A: Yes. Both parts have identical axial dimensions of 0.217" Dia x 0.591" L (5.50mm x 15.00mm), ensuring identical PCB footprint and mounting characteristics.
