Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 41F200 are qualified based on the following critical parameters:

• Resistance value: 200 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 1W (exact match required)
• Composition: Wirewound (exact match required)
• Package: Axial through-hole (exact match required)
• Number of terminations: 2 (exact match required)

The identified substitutes maintain these core electrical and mechanical specifications. Variations in temperature coefficient, operating temperature range, physical dimensions, RoHS compliance status, and moisture resistance features are secondary parameters that may influence selection based on application requirements but do not disqualify substitution eligibility.

Parameter Comparison

Engineering Selection Recommendations

41F200E (Ohmite): This direct Ohmite substitute maintains identical electrical specifications and physical dimensions to the 41F200. The primary distinction is RoHS compliance status; the 41F200E is RoHS Compliant, whereas the original 41F200 is non-compliant. Selection of 41F200E is appropriate for applications requiring RoHS-compliant components or when supply from the same manufacturer is preferred. Operating temperature range is specified as -55°C ~ 275°C.

ALSR01200R0FE12 (Vishay Dale): This cross-manufacturer substitute meets all core electrical requirements (200 Ohms, ±1%, 1W, wirewound, axial). The ALSR series includes moisture-resistant features and achieves ROHS3 compliance. Physical dimensions are slightly smaller (0.110" Dia x 0.406" L versus 0.126" Dia x 0.437" L), which may be advantageous in space-constrained layouts. Temperature coefficient is ±30ppm/°C (versus ±20ppm/°C for Ohmite parts) and operating temperature range is -65°C ~ 250°C. Selection is appropriate for applications requiring enhanced moisture resistance, superior RoHS compliance status, or when Vishay Dale supply chain access is preferred.

Frequently Asked Questions (FAQ)

Q: Can 41F200E be used as a direct replacement for 41F200?

A: Yes. Both parts share identical resistance (200 Ohms), tolerance (±1%), power rating (1W), composition (wirewound), and physical dimensions (0.126" Dia x 0.437" L). The primary difference is RoHS compliance status. Electrical performance is equivalent.

Q: What are the physical dimension differences between ALSR01200R0FE12 and the Ohmite parts?

A: ALSR01200R0FE12 has a smaller diameter (0.110" versus 0.126") and shorter length (0.406" versus 0.437"). These dimensional differences may affect PCB layout and mechanical fit. Verify clearance in your specific application before substitution.

Q: Does the ±30ppm/°C temperature coefficient of ALSR01200R0FE12 affect substitution eligibility?

A: The ALSR01200R0FE12 has a slightly higher temperature coefficient (±30ppm/°C) compared to Ohmite parts (±20ppm/°C). This difference is secondary to the core electrical specifications and does not disqualify substitution. Evaluate based on your application's temperature stability requirements.

Q: Which substitute part has the best compliance certifications?

A: ALSR01200R0FE12 carries ROHS3 compliance, which represents the most current RoHS standard. 41F200E is RoHS Compliant. The original 41F200 is RoHS non-compliant. Selection depends on your regulatory and procurement requirements.

Q: Are all three parts suitable for high-temperature applications?

A: 41F200E supports -55°C ~ 275°C, offering the highest upper temperature limit. ALSR01200R0FE12 supports -65°C ~ 250°C, providing the lowest lower temperature limit. The original 41F200 does not specify an operating temperature range. Verify compatibility with your application's thermal requirements.

Q: Can ALSR01200R0FE12 be used in moisture-sensitive environments?

A: Yes. ALSR01200R0FE12 includes moisture-resistant features and carries MSL 1 (Unlimited) rating, making it suitable for moisture-sensitive applications. The Ohmite parts do not specify moisture resistance features.
