CW01020K00JS73 Equivalent & Substitute Parts

Part Overview

The CW01020K00JS73 is a 20 kOhms ±5% 13W through-hole resistor manufactured by Vishay Dale in the CW series. This axial wirewound resistor features moisture-resistant construction and operates across a wide temperature range from -65°C to 350°C. The component is currently in active production status. Substitute parts are necessary when the original packaging format (Tape & Reel) is unavailable or when compliance requirements differ between procurement sources.

Substitute Part Grouping Explanation

The CW01020K00JE73 qualifies as a parametric equivalent to the CW01020K00JS73 based on the following criteria:

• Identical resistance value: 20 kOhms
• Identical tolerance: ±5%
• Identical power rating: 13W
• Identical composition: Wirewound
• Identical package type: Axial
• Identical temperature coefficient: ±30ppm/°C
• Identical operating temperature range: -65°C to 350°C
• Identical physical dimensions: 0.375" Dia x 1.781" L (9.52mm x 45.24mm)
• Identical number of terminations: 2
• Same manufacturer: Vishay Dale
• Same series: CW

The primary difference between these parts is the packaging format: the main part is supplied in Tape & Reel (TR) configuration, while the substitute is supplied in Cut Tape (CT) configuration. Both formats contain identical components with no functional or electrical differences.

Parameter Comparison

Engineering Selection Recommendations

Both CW01020K00JS73 and CW01020K00JE73 are active production components from Vishay Dale with identical electrical and mechanical specifications. Selection between these parts should be based on the following factors:

CW01020K00JS73 (Tape & Reel): Use when bulk quantities require automated assembly processing or when Tape & Reel packaging is specified in procurement requirements.

CW01020K00JE73 (Cut Tape): Use when Cut Tape packaging is acceptable or preferred. This variant offers ROHS3 compliance and REACH unaffected status, which may be required for certain regulatory or customer specifications.

Both parts are suitable for high-temperature applications up to 350°C and moisture-resistant environments. The choice between them is determined by packaging requirements and compliance certifications rather than functional performance.

Frequently Asked Questions (FAQ)

Q: Can CW01020K00JE73 be used as a direct replacement for CW01020K00JS73?

A: Yes. Both parts are electrically and mechanically identical. The only difference is the packaging format (Cut Tape versus Tape & Reel). Direct substitution is valid for applications where packaging format does not affect assembly processes.

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

A: Tape & Reel packaging supplies components on a continuous reel suitable for automated pick-and-place assembly equipment. Cut Tape packaging supplies the same components cut from the tape in smaller quantities, typically for manual assembly or lower-volume applications.

Q: Are there compliance differences between these parts?

A: Yes. CW01020K00JE73 is ROHS3 compliant and REACH unaffected, while CW01020K00JS73 is RoHS non-compliant and REACH affected. Applications subject to RoHS3 or REACH regulations should use CW01020K00JE73.

Q: Do these resistors have identical thermal performance?

A: Yes. Both parts have identical temperature coefficients (±30ppm/°C) and operating temperature ranges (-65°C to 350°C), ensuring equivalent thermal performance in circuit applications.

Q: Can these parts be used interchangeably in high-temperature applications?

A: Yes. Both CW01020K00JS73 and CW01020K00JE73 are rated for continuous operation up to 350°C and feature moisture-resistant construction, making them suitable for identical high-temperature applications.
