Substitute Part Grouping Explanation

The CW010100R0JE73 qualifies as a parametric equivalent to the CW010100R0JS73 based on the following critical parameters:

Electrical specifications are identical: 100 Ohms resistance, ±5% tolerance, 13W power rating, ±30ppm/°C temperature coefficient, and -65°C to 350°C operating temperature range. Physical dimensions match exactly at 0.375" Dia x 1.781" L. Both components use wirewound composition with moisture-resistant features and maintain the same axial package configuration with 2 terminations.

The primary distinction between these parts is packaging format: CW010100R0JS73 is supplied in Tape & Reel (TR) configuration, while CW010100R0JE73 is supplied in Cut Tape (CT) configuration. Additionally, CW010100R0JE73 achieves RoHS3 compliance, whereas CW010100R0JS73 is RoHS non-compliant.

Parameter Comparison

Engineering Selection Recommendations

Both CW010100R0JS73 and CW010100R0JE73 are active production components from Vishay Dale with identical electrical and mechanical specifications. Selection between these parts depends on two factors:

Packaging requirements determine the primary choice. The CW010100R0JS73 in Tape & Reel format suits automated assembly processes, while the CW010100R0JE73 in Cut Tape format accommodates manual assembly or lower-volume production runs.

Regulatory compliance is the secondary consideration. Applications requiring RoHS3 compliance must use CW010100R0JE73. The CW010100R0JS73 remains suitable for applications without RoHS compliance mandates. Both parts maintain REACH Affected or REACH Unaffected status as specified.

Frequently Asked Questions (FAQ)

Q: Are CW010100R0JS73 and CW010100R0JE73 electrically interchangeable?

A: Yes. Both components deliver identical electrical performance with 100 Ohm resistance, ±5% tolerance, 13W power rating, ±30ppm/°C temperature coefficient, and -65°C to 350°C operating range.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging supplies components on continuous tape wound on reels, optimized for high-speed automated pick-and-place assembly. Cut Tape (CT) packaging supplies components on tape segments cut to specific lengths, suitable for manual assembly or lower-volume applications.

Q: Can I substitute CW010100R0JS73 with CW010100R0JE73 in existing designs?

A: Electrical and mechanical substitution is direct. Verify packaging compatibility with your assembly process. If RoHS3 compliance is required, CW010100R0JE73 is the appropriate choice.

Q: Do these resistors have identical physical dimensions?

A: Yes. Both components measure 0.375" diameter by 1.781" length (9.52mm x 45.24mm) in axial configuration.

Q: What is the temperature coefficient specification, and why does it matter?

A: Both parts specify ±30ppm/°C temperature coefficient. This indicates the resistance change per degree Celsius across the operating range. For precision applications requiring stable resistance across temperature variations, this specification ensures predictable performance.
