Substitute Part Grouping Explanation

Substitute parts for the CW001100R0JS70 are categorized based on the following substitution criteria:

Direct Substitute (Packaging Variant): CW001100R0JE70 maintains identical electrical specifications (100 Ohms ±5%, wirewound, moisture resistant, ±30ppm/°C temperature coefficient, -65°C ~ 350°C operating range) and physical dimensions. The primary difference is packaging format: Cut Tape (CT) instead of Tape & Reel (TR). This part achieves ROHS3 compliance, whereas the main part is RoHS non-compliant.

Upgrade Substitute (Enhanced Performance): RS01A100R0FS70 provides improved tolerance (±1% versus ±5%), increased power rating (1W versus unspecified), and lower temperature coefficient (±20ppm/°C versus ±30ppm/°C). Resistance value and physical dimensions remain identical. Operating temperature range is -65°C ~ 250°C. This part is RoHS non-compliant but REACH Affected.

Parameter Comparison

Engineering Selection Recommendations

CW001100R0JE70 is selected when Cut Tape packaging is required instead of Tape & Reel format, and RoHS3 compliance is mandatory. Electrical performance is functionally equivalent to the main part. This substitute is suitable for applications with regulatory requirements for RoHS compliance.

RS01A100R0FS70 is selected when enhanced tolerance (±1%) and lower temperature coefficient (±20ppm/°C) are required for precision applications. The 1W power rating provides increased thermal capability. This upgrade substitute is appropriate for circuits requiring tighter resistance tolerances and improved stability across temperature variations. The reduced operating temperature maximum of 250°C versus 350°C must be verified against application requirements.

Frequently Asked Questions (FAQ)

Q: Can CW001100R0JE70 be used as a direct replacement for CW001100R0JS70? A: Yes. Both parts have identical electrical specifications (100 Ohms ±5%, wirewound, moisture resistant, ±30ppm/°C, -65°C ~ 350°C). The difference is packaging format: CW001100R0JE70 is supplied in Cut Tape instead of Tape & Reel. CW001100R0JE70 also achieves ROHS3 compliance.

Q: What are the key differences between CW001100R0JS70 and RS01A100R0FS70? A: RS01A100R0FS70 offers improved tolerance (±1% versus ±5%), lower temperature coefficient (±20ppm/°C versus ±30ppm/°C), and specified 1W power rating. Operating temperature range is reduced to -65°C ~ 250°C. These are performance enhancements, not direct equivalents.

Q: Which substitute should I select for RoHS-compliant applications? A: CW001100R0JE70 is ROHS3 compliant and maintains identical electrical specifications to the main part. It is the appropriate choice for RoHS-regulated applications.

Q: Are physical dimensions identical across all three parts? A: Yes. All three parts share identical axial package dimensions: 0.094" Dia x 0.406" L (2.39mm x 10.31mm). They are mechanically interchangeable on PCBs.

Q: Can RS01A100R0FS70 be used in applications requiring operation above 250°C? A: No. RS01A100R0FS70 has a maximum operating temperature of 250°C, whereas CW001100R0JS70 and CW001100R0JE70 operate to 350°C. Applications requiring temperatures above 250°C must use the original part or CW001100R0JE70.
