RSF2JB20R0 Equivalent & Substitute Parts

Part Overview

The RSF2JB20R0 is a 20 Ohm, 2W axial through-hole resistor manufactured by Stackpole Electronics Inc. This metal oxide film resistor features flame retardant coating and safety characteristics, designed for applications requiring reliable power dissipation in compact form factors. 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 configuration is unavailable or when supply chain flexibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RSF2JB20R0 is determined by electrical and mechanical parameter equivalence within the RSF series. The substitute part RSF2JT20R0 maintains identical electrical specifications: 20 Ohm resistance, ±5% tolerance, 2W power rating, metal oxide film composition, ±200ppm/°C temperature coefficient, and -55°C to 235°C operating range. Physical dimensions, termination count, and compliance certifications remain unchanged. The primary distinction between these parts is packaging configuration: RSF2JB20R0 is supplied in Bulk packaging, while RSF2JT20R0 is supplied in Cut Tape (CT) format. Both parts are manufactured by Stackpole Electronics Inc within the active RSF product series.

Parameter Comparison

Engineering Selection Recommendations

Both RSF2JB20R0 and RSF2JT20R0 are functionally equivalent for circuit applications requiring 20 Ohm, 2W axial resistors. Selection between these parts is determined by procurement and assembly requirements rather than electrical performance. The RSF2JB20R0 in Bulk packaging is suitable for high-volume manual assembly or bin storage applications. The RSF2JT20R0 in Cut Tape format is optimized for automated pick-and-place assembly processes and tape-reel handling systems. Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility across manufacturing environments. Current inventory levels support both configurations, with RSF2JT20R0 offering higher stock availability at 3577 pieces compared to RSF2JB20R0 at 1056 pieces.

Frequently Asked Questions (FAQ)

Q: Can RSF2JT20R0 be used as a direct replacement for RSF2JB20R0 in circuit design?

A: Yes. Both parts are electrically and mechanically identical. The difference is packaging format only. RSF2JT20R0 in Cut Tape can be substituted for RSF2JB20R0 in Bulk without circuit redesign or performance impact.

Q: What is the difference between Bulk and Cut Tape packaging?

A: Bulk packaging supplies loose components suitable for manual handling and bin storage. Cut Tape packaging supplies components on continuous tape in reel format, optimized for automated assembly equipment. Both contain identical components.

Q: Are there any compliance differences between these substitute parts?

A: No. Both RSF2JB20R0 and RSF2JT20R0 carry identical ROHS3 compliance and REACH unaffected status. Regulatory requirements are met by either part.

Q: What determines whether a part can substitute for the RSF2JB20R0?

A: Substitution requires matching resistance value (20 Ohms), tolerance (±5%), power rating (2W), composition (metal oxide film), temperature coefficient (±200ppm/°C), operating temperature range (-55°C to 235°C), and physical dimensions (0.217" Dia x 0.591" L). Packaging format does not affect electrical substitutability.

Q: Which part should be selected for automated assembly?

A: RSF2JT20R0 in Cut Tape format is designed for automated pick-and-place systems and tape-reel handling. RSF2JB20R0 in Bulk format is suited for manual assembly processes.
