Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CW001R2000JS70 is determined by the following critical parameters:

• Resistance value: 200 mOhms (exact match required)
• Tolerance: ±5% (exact match required)
• Composition: Wirewound (exact match required)
• Package: Axial through-hole (exact match required)
• Terminations: 2-pin configuration (exact match required)

The substitute part 41JR20 (Ohmite) satisfies all mandatory electrical and mechanical compatibility criteria. Both parts share identical resistance, tolerance, wirewound composition, and axial package configuration with two terminations. Physical dimensions differ slightly, but both conform to standard axial resistor form factors suitable for equivalent board-level integration.

Parameter Comparison

Engineering Selection Recommendations

Both the CW001R2000JS70 and 41JR20 are active products with identical electrical specifications (200 mOhms, ±5% tolerance, wirewound composition). Selection between these parts depends on application-specific requirements not fully specified in the provided parameters.

The CW001R2000JS70 features moisture-resistant construction and operates across -65°C to 350°C. The 41JR20 provides 1W power rating and ±90ppm/°C temperature coefficient specifications. Both parts are RoHS non-compliant and classified under HTSUS 8533.21.0080.

Physical dimensions differ: the CW001R2000JS70 measures 0.094" diameter by 0.406" length, while the 41JR20 measures 0.126" diameter by 0.437" length. Board layout constraints and thermal management requirements should guide final component selection.

Frequently Asked Questions (FAQ)

Q: Can the 41JR20 directly replace the CW001R2000JS70 in all applications?

A: Both parts share identical resistance (200 mOhms) and tolerance (±5%) with wirewound composition and axial package configuration. Physical dimensions differ slightly. Verify that board layout accommodates the 41JR20's larger form factor (0.126" diameter versus 0.094" diameter) before substitution.

Q: What are the key electrical parameters that define substitution compatibility?

A: Resistance value, tolerance, composition type, and package configuration determine substitution eligibility. The CW001R2000JS70 and 41JR20 match on all four criteria, establishing electrical equivalence.

Q: How do the operating temperature ranges compare?

A: The CW001R2000JS70 specifies -65°C to 350°C operation. The 41JR20 does not provide an operating temperature range in the available specifications. Applications requiring the full -65°C to 350°C range should confirm 41JR20 capability with the manufacturer.

Q: Are there packaging differences between these parts?

A: The CW001R2000JS70 is supplied in tape and reel (TR) packaging with 991 units in stock. The 41JR20 is supplied in bulk packaging with 982 units in stock. Procurement and handling processes may differ accordingly.

Q: What is the significance of the power rating difference?

A: The 41JR20 specifies 1W power rating. The CW001R2000JS70 power rating is not provided in the available data. Power dissipation requirements in the target application should be evaluated against the 41JR20's 1W specification.
