Substitute Part Grouping Explanation

Substitution eligibility for the RWR89N2000FRBSL is determined by strict equivalence across the following critical parameters:

• Resistance value: 200 Ohms
• Tolerance: ±1%
• Power rating: 3W
• Composition: Wirewound
• Package configuration: Axial through-hole
• Temperature coefficient: ±20ppm/°C
• Operating temperature range: -55°C to 250°C
• Military specification compliance: MIL-PRF-39007
• Failure rate classification: R (0.01%)
• Physical dimensions: 0.187" Dia × 0.560" L

The RWR89S2000FRB12 meets all substitution criteria as a parametric equivalent within the Vishay Dale RWR89 military resistor series. Both parts share identical electrical specifications and mechanical form factors, differing only in internal construction details (non-inductive vs. standard moisture-resistant design) that do not affect functional interchangeability in circuit applications.

Engineering Selection Recommendations

Both the RWR89N2000FRBSL and RWR89S2000FRB12 maintain active product status and comply with MIL-PRF-39007 military specifications. Selection between these parts should be based on availability and supply chain requirements. The RWR89S2000FRB12 currently maintains higher inventory levels (1180 units vs. 714 units), which may provide supply chain advantages for high-volume applications. Both parts carry identical REACH and ECCN classifications (REACH Affected, EAR99), ensuring equivalent compliance posture for export and regulatory purposes. Neither part achieves RoHS compliance, consistent with military-grade wirewound resistor specifications.

Frequently Asked Questions (FAQ)

Q: Can RWR89S2000FRB12 be used as a direct replacement for RWR89N2000FRBSL?

A: Yes. Both parts are parametric equivalents with identical resistance, tolerance, power rating, temperature coefficient, operating range, and physical dimensions. They are functionally interchangeable in circuit applications.

Q: What is the difference between the non-inductive (RWR89N) and standard moisture-resistant (RWR89S) variants?

A: The RWR89N includes non-inductive winding construction, while the RWR89S uses standard moisture-resistant construction. Both maintain identical electrical performance and mechanical compatibility. Selection depends on circuit requirements for inductance characteristics.

Q: Are there any package or footprint differences between these parts?

A: No. Both parts share identical axial package configuration with 0.187" diameter and 0.560" length (4.75mm × 14.22mm). PCB layout and mounting procedures are identical.

Q: Do both parts meet the same military specifications?

A: Yes. Both parts comply with MIL-PRF-39007 military specifications and carry identical failure rate classifications of R (0.01%).

Q: What is the temperature coefficient significance for these resistors?

A: The ±20ppm/°C temperature coefficient indicates resistance value change across the -55°C to 250°C operating range. Both parts maintain this specification, ensuring predictable performance in temperature-variable environments.

Q: Are there compliance or export restrictions for these parts?

A: Both parts are classified as REACH Affected and EAR99 for export purposes. Neither achieves RoHS compliance. Regulatory requirements should be verified for specific applications and jurisdictions.
