Substitute Part Grouping Explanation

Substitute parts for the Ohmite 81F200 are qualified based on strict electrical and mechanical equivalence. The following parameters must match identically:

• Resistance value: 200 Ohms
• Tolerance: ±1%
• Power rating: 1W
• Composition: Wirewound
• Package configuration: Axial
• Temperature coefficient: ±20ppm/°C
• Physical dimensions: 0.126" Dia x 0.437" L (3.20mm x 11.10mm)
• Number of terminations: 2

The Ohmite 41F200E meets all substitution criteria as a parametric equivalent within the Ohmite product portfolio.

Engineering Selection Recommendations

Both the Ohmite 81F200 and 41F200E are active products with identical electrical and mechanical specifications. Selection between these parts should be based on the following factors:

RoHS Compliance: The 41F200E is RoHS Compliant, while the 81F200 is RoHS non-compliant. Applications subject to RoHS regulations require the 41F200E.

Operating Temperature Range: The 41F200E specifies an operating temperature range of -55°C ~ 275°C. The 81F200 does not provide this specification. Applications with defined temperature requirements should reference the 41F200E datasheet.

Packaging: The 81F200 is supplied in standard packaging, while the 41F200E is available in Bulk packaging. Procurement volume and handling requirements may influence packaging selection.

Inventory Availability: The 81F200 maintains higher current inventory (1027 units) compared to the 41F200E (721 units).

Frequently Asked Questions (FAQ)

Q: Can the 41F200E directly replace the 81F200 in existing designs?

A: Yes. Both parts share identical electrical parameters (200 Ohms ±1%, 1W, ±20ppm/°C) and mechanical dimensions (0.126" Dia x 0.437" L). Physical form factor and termination configuration are identical, enabling direct substitution in axial through-hole applications.

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

A: The 41F200E is RoHS Compliant with a specified operating temperature range of -55°C ~ 275°C, while the 81F200 is RoHS non-compliant without a specified temperature range. Both maintain identical resistance, tolerance, power rating, and physical dimensions.

Q: Which part should be selected for new designs?

A: Selection depends on regulatory and environmental requirements. For applications requiring RoHS compliance or operating within the -55°C ~ 275°C range, the 41F200E is the appropriate choice. Both parts are active products suitable for new designs.

Q: Are there packaging differences between these parts?

A: The 81F200 uses standard packaging, while the 41F200E is supplied in Bulk packaging. Packaging selection should align with procurement volume and handling procedures.

Q: Do these parts have identical thermal characteristics?

A: Both parts specify an identical temperature coefficient of ±20ppm/°C. The 41F200E provides an explicit operating temperature range of -55°C ~ 275°C. Thermal performance is equivalent within specified operating conditions.
