Substitute Part Grouping Explanation

Substitute parts for the RWR89S2R00FSBSL are identified based on strict equivalence across the following critical parameters:

• Resistance value: 2 Ohms
• Tolerance: ±1%
• Power rating: 3W
• Composition: Wirewound
• Package: Axial
• Temperature coefficient: ±50ppm/°C
• Operating temperature range: -55°C to 250°C
• Physical dimensions: 0.187" Dia x 0.560" L
• Military series compliance: MIL-PRF-39007, RWR89S
• Moisture resistance: Yes

The RWR89S2R00FRB12 meets all these criteria and qualifies as a direct substitute. Both parts share identical base product designation (RWR89) and maintain equivalent electrical performance and physical form factor.

Parameter Comparison

Engineering Selection Recommendations

Both the RWR89S2R00FSBSL and RWR89S2R00FRB12 are active products manufactured by Vishay Dale with identical electrical and mechanical specifications. Selection between these parts should be based on:

• Inventory availability: RWR89S2R00FRB12 has higher current stock (1010 units vs. 676 units)
• Failure rate classification: RWR89S2R00FSBSL carries a lower failure rate (S grade at 0.001% vs. R grade at 0.01%)
• Compliance requirements: Both parts share identical RoHS non-compliant and REACH Affected status, with matching ECCN and HTSUS classifications

For applications requiring the lowest failure rate specification, RWR89S2R00FSBSL is the primary choice. For applications where inventory lead time is critical, RWR89S2R00FRB12 provides equivalent performance with greater availability.

Frequently Asked Questions (FAQ)

Q: Can RWR89S2R00FRB12 be used as a direct replacement for RWR89S2R00FSBSL?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters: 2 Ohm resistance, ±1% tolerance, 3W power rating, wirewound composition, axial package, and military MIL-PRF-39007 compliance. The only difference is the failure rate classification and current inventory levels.

Q: What is the difference in failure rate between these two parts?

A: RWR89S2R00FSBSL carries a failure rate of S (0.001%), while RWR89S2R00FRB12 carries a failure rate of R (0.01%). Applications requiring the lowest failure rate specification should specify RWR89S2R00FSBSL.

Q: Are the physical dimensions identical?

A: Yes. Both parts have identical dimensions of 0.187" diameter by 0.560" length (4.75mm x 14.22mm), ensuring identical PCB footprint and mounting compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts share identical RoHS non-compliant status, REACH Affected designation, EAR99 ECCN classification, and 8533.21.0080 HTSUS code.

Q: Which part should be selected for new designs?

A: Selection depends on design requirements. For lowest failure rate applications, specify RWR89S2R00FSBSL. For applications where inventory availability is the primary concern, RWR89S2R00FRB12 provides equivalent performance with higher current stock levels.
