Substitute Part Grouping Explanation

The RSF2JT3R00 qualifies as a direct substitute for the RSF2JB3R00 based on identical electrical and mechanical parameters. Both parts share the same resistance value (3 Ohms), tolerance (±5%), power rating (2W), composition (metal oxide film), temperature coefficient (±200ppm/°C), operating temperature range (-55°C ~ 235°C), package type (Axial), and physical dimensions (0.217" Dia x 0.591" L). The substitution is valid across all electrical performance criteria and mechanical compatibility requirements. The primary difference is packaging format: RSF2JB3R00 is supplied in Bulk packaging, while RSF2JT3R00 is supplied in Cut Tape (CT) packaging. Both parts maintain identical compliance certifications (ROHS3 Compliant, REACH Unaffected, EAR99 ECCN classification).

Parameter Comparison

Engineering Selection Recommendations

The RSF2JT3R00 is a valid substitute for the RSF2JB3R00 in all electrical and mechanical applications. Both parts are Active products from the same manufacturer with identical compliance certifications. Selection between these parts should be based on packaging requirements and supply chain logistics. The Bulk packaging format (RSF2JB3R00) is suitable for high-volume manufacturing environments, while the Cut Tape (CT) format (RSF2JT3R00) is optimized for automated pick-and-place assembly processes. Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility across global markets.

Frequently Asked Questions (FAQ)

Q: Can RSF2JT3R00 replace RSF2JB3R00 in circuit designs? A: Yes. Both parts have identical electrical specifications (3 Ohms, ±5% tolerance, 2W power rating) and mechanical dimensions (0.217" Dia x 0.591" L). They are functionally interchangeable in all circuit applications.

Q: What is the difference between Bulk and Cut Tape packaging? A: Bulk packaging supplies loose components suitable for manual assembly or bin storage. Cut Tape (CT) packaging supplies components on continuous tape, optimized for automated assembly equipment. The electrical and mechanical performance of the component is identical regardless of packaging format.

Q: Are both parts RoHS compliant? A: Yes. Both RSF2JB3R00 and RSF2JT3R00 are ROHS3 Compliant and REACH Unaffected, meeting regulatory requirements for electronic component use in restricted substance directives.

Q: Do these parts have the same operating temperature range? A: Yes. Both parts operate across the identical temperature range of -55°C to 235°C with a temperature coefficient of ±200ppm/°C.

Q: Which part should I select for my application? A: Selection depends on your assembly process. Use RSF2JB3R00 (Bulk) for manual assembly or bin-based manufacturing. Use RSF2JT3R00 (Cut Tape) for automated pick-and-place assembly lines. Electrical performance and reliability are equivalent.
