Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RWR89S2000FSBSL is determined by strict equivalence across the following critical parameters:

• Resistance value: 200 Ohms
• Tolerance: ±1%
• Power rating: 3W
• Composition: Wirewound
• Package: Axial
• Temperature coefficient: ±20ppm/°C
• Operating temperature range: -55°C to 250°C
• Physical dimensions: 0.187" Dia x 0.560" L
• Series compliance: Military, MIL-PRF-39007, RWR89S

The RWR89S2000FRB12 meets all substitution criteria as a direct equivalent within the same military-grade RWR89S series, maintaining identical electrical specifications and physical form factor.

Parameter Comparison

Engineering Selection Recommendations

Both the RWR89S2000FSBSL and RWR89S2000FRB12 are active production parts from Vishay Dale with identical electrical and mechanical specifications. Selection between these parts should be based on:

• Inventory availability: RWR89S2000FRB12 has higher stock levels (1180 units vs. 908 units)
• Failure rate classification: RWR89S2000FSBSL carries a lower failure rate (S grade at 0.001%) compared to RWR89S2000FRB12 (R grade at 0.01%)
• Regulatory compliance: Both parts share identical RoHS non-compliant and REACH Affected status, with EAR99 export classification

For applications where failure rate is a critical design parameter, the RWR89S2000FSBSL is the preferred selection. For general sourcing flexibility, the RWR89S2000FRB12 offers superior availability.

Frequently Asked Questions (FAQ)

Q: Can RWR89S2000FRB12 be used as a direct replacement for RWR89S2000FSBSL?

A: Yes. Both parts are electrically and mechanically equivalent, sharing identical resistance (200 Ohms), tolerance (±1%), power rating (3W), temperature coefficient (±20ppm/°C), operating range (-55°C to 250°C), and axial package dimensions (0.187" Dia x 0.560" L). Both comply with MIL-PRF-39007 military specifications.

Q: What is the difference between these two parts?

A: The primary differences are failure rate classification and current inventory levels. RWR89S2000FSBSL has a lower failure rate (S grade, 0.001%) versus RWR89S2000FRB12 (R grade, 0.01%). RWR89S2000FRB12 has higher stock availability (1180 units vs. 908 units).

Q: Are there any package or form factor differences?

A: No. Both parts are identical axial wirewound resistors with the same physical dimensions and mounting characteristics.

Q: Do these parts have the same regulatory compliance status?

A: Yes. Both parts are RoHS non-compliant, REACH Affected, and classified as EAR99 for export purposes.

Q: Which part should I select for high-reliability applications?

A: For applications where reliability metrics are specified, RWR89S2000FSBSL is the appropriate selection due to its lower failure rate classification (S grade).
