Substitute Part Grouping Explanation

Substitution eligibility for the Ohmite 83F200 is determined by strict equivalence across the following critical parameters:

• Resistance value: 200 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 3W (exact match required)
• Composition: Wirewound (exact match required)
• Package: Axial through-hole (exact match required)
• Temperature coefficient: ±20ppm/°C (exact match required)
• Termination count: 2 (exact match required)

The Vishay Dale RS02B200R0FS70 meets all substitution criteria. This part is qualified as a manufacturer-recommended substitute, maintaining electrical equivalence while offering moisture-resistant construction and an extended operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

Both the Ohmite 83F200 and Vishay Dale RS02B200R0FS70 are active products with equivalent electrical specifications. Selection between these parts should be based on the following factors:

The Ohmite 83F200 is the primary specification. The Vishay Dale RS02B200R0FS70 serves as a qualified substitute when the primary part is unavailable. The Vishay part offers moisture-resistant construction and operates across an extended temperature range (-65°C to 250°C), providing enhanced environmental protection in applications subject to humidity exposure. Both parts are RoHS non-compliant and carry identical ECCN and HTSUS classifications.

Physical dimensions differ slightly between the two parts. The Vishay substitute is marginally smaller in both diameter and length, which may provide advantages in space-constrained layouts while maintaining full electrical equivalence.

Frequently Asked Questions (FAQ)

Q: Can the Vishay Dale RS02B200R0FS70 be used as a direct replacement for the Ohmite 83F200?

A: Yes. Both parts share identical electrical specifications: 200 Ohms ±1% at 3W with ±20ppm/°C temperature coefficient. The Vishay part is manufacturer-recommended as a substitute and maintains full functional equivalence.

Q: What is the primary difference between these two parts?

A: The Vishay Dale RS02B200R0FS70 includes moisture-resistant construction and specifies an operating temperature range of -65°C to 250°C. The Ohmite 83F200 does not specify an operating temperature range. Physical dimensions are also slightly different, with the Vishay part being more compact.

Q: Are there any package or mounting differences?

A: Both parts use axial through-hole packaging with identical termination configuration (2 leads). Physical dimensions vary slightly: Ohmite measures 0.217" diameter × 0.594" length, while Vishay measures 0.187" diameter × 0.560" length. Both are compatible with standard through-hole PCB layouts, though the Vishay part occupies marginally less board space.

Q: Do these parts have different compliance certifications?

A: Both parts are RoHS non-compliant and carry identical ECCN (EAR99) and HTSUS (8533.21.0080) classifications. The Vishay part is REACH Affected, while the Ohmite part is REACH Unaffected.

Q: Which part should I specify for new designs?

A: Selection depends on application requirements. For standard applications, either part is acceptable. For environments with moisture exposure or applications requiring extended temperature operation, the Vishay Dale RS02B200R0FS70 offers enhanced environmental protection.
