Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Ohmite 43F200 is determined by strict equivalence across the following 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)
• Number of terminations: 2 (exact match required)

All substitute parts listed below meet these core electrical and mechanical requirements. Variations in temperature coefficient, operating temperature range, physical dimensions, RoHS compliance status, and packaging format are permitted within the substitution framework.

Parameter Comparison

Engineering Selection Recommendations

All four parts are actively manufactured and available in stock. Selection between the main part and substitutes should be based on the following criteria:

Ohmite 43F200E — Direct manufacturer equivalent with identical electrical specifications and physical dimensions. Offers RoHS compliance and extended upper operating temperature limit (-55°C ~ 275°C). Suitable for applications requiring regulatory compliance and higher temperature operation.

Vishay Dale ALSR03200R0FE12 — Moisture-resistant wirewound construction with ROHS3 compliance. Operates across -65°C ~ 250°C range. Smaller physical dimensions (0.180" Dia x 0.500" L) may be advantageous in space-constrained layouts. Temperature coefficient of ±30ppm/°C represents a minor deviation from the primary specification.

Vishay Dale RS02B200R0FS70 — Moisture-resistant wirewound with identical temperature coefficient (±20ppm/°C) and extended lower temperature rating (-65°C). Highest inventory availability (1419 units). Maintains RoHS non-compliant status consistent with the original part. Physical dimensions (0.187" Dia x 0.560" L) fall between the primary part and ALSR variant.

Frequently Asked Questions (FAQ)

Q: Can the Ohmite 43F200E be used as a direct replacement for the Ohmite 43F200?

A: Yes. The 43F200E is a direct equivalent with identical resistance, tolerance, power rating, composition, and physical dimensions. The primary differences are RoHS compliance status and extended operating temperature range (-55°C ~ 275°C versus unspecified for the original).

Q: What is the significance of the moisture-resistant feature on the Vishay Dale parts?

A: Moisture-resistant construction provides enhanced performance in humid or corrosive environments. This feature is not present on the Ohmite parts but does not prevent substitution in standard applications where moisture resistance is not required.

Q: Are there physical dimension constraints when substituting the Vishay Dale ALSR03200R0FE12?

A: Yes. The ALSR variant is physically smaller (0.180" Dia x 0.500" L) compared to the Ohmite 43F200 (0.220" Dia x 0.594" L). Verify PCB layout and mechanical clearances before selection, particularly in applications with tight spatial requirements.

Q: Which substitute part offers the best compliance profile?

A: The Ohmite 43F200E and Vishay Dale ALSR03200R0FE12 both carry RoHS compliance certifications. The 43F200E provides RoHS compliance with the widest operating temperature range. The ALSR variant provides ROHS3 compliance with moisture-resistant construction.

Q: What is the difference between the Ohmite 43F200 and 43F200E packaging?

A: The primary part uses standard packaging format, while the 43F200E is supplied in bulk packaging. Both maintain identical electrical and mechanical specifications.

Q: Can I use the Vishay Dale RS02B200R0FS70 in applications requiring RoHS compliance?

A: No. The RS02B200R0FS70 carries RoHS non-compliant status. Use the Ohmite 43F200E or Vishay Dale ALSR03200R0FE12 for applications with RoHS compliance requirements.
