CW01020K00JS733 Equivalent & Substitute Parts

Part Overview

The CW01020K00JS733 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 part is currently active in production and available in Tape & Reel packaging with 1055 units in stock. Substitute parts are necessary when specific packaging formats, compliance requirements, or inventory availability differ from the original specification.

Substitute Part Grouping Explanation

Substitution eligibility for the CW01020K00JS733 is determined by electrical and mechanical parameter equivalence. All substitute parts must maintain identical specifications for resistance value (20 kOhms), tolerance (±5%), power rating (13W), composition (wirewound), package type (axial), temperature coefficient (±30ppm/°C), operating temperature range (-65°C to 350°C), physical dimensions (0.375" Dia x 1.781" L), and moisture-resistant features. Packaging format (Tape & Reel, Cut Tape, or Bulk) and compliance certifications may vary without affecting functional equivalence. The identified substitutes CW01020K00JE12 and CW01020K00JE73 meet all electrical and mechanical requirements for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

CW01020K00JE73 is the preferred substitute when Cut Tape packaging is acceptable, offering the highest inventory availability (2271 units) and ROHS3 compliance with REACH unaffected status. CW01020K00JE12 serves as an alternative when Bulk packaging meets assembly requirements, with ROHS3 compliance and REACH unaffected status. Both substitutes provide identical electrical and mechanical performance to the original CW01020K00JS733. Selection between substitutes should prioritize packaging format compatibility with manufacturing processes and compliance requirements for the end application. The original CW01020K00JS733 in Tape & Reel format remains suitable for automated assembly operations requiring that specific packaging configuration.

Frequently Asked Questions (FAQ)

Q: Can CW01020K00JE12 and CW01020K00JE73 be used interchangeably with CW01020K00JS733?

A: Yes. All three parts are electrically and mechanically equivalent, sharing identical resistance (20 kOhms), tolerance (±5%), power rating (13W), temperature coefficient (±30ppm/°C), operating temperature range (-65°C to 350°C), and physical dimensions (0.375" Dia x 1.781" L). Differences exist only in packaging format and compliance certifications.

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

A: Tape & Reel (TR) packaging supplies components on continuous tape wound on reels, optimized for automated pick-and-place assembly. Cut Tape (CT) provides components on tape segments cut to specified lengths for semi-automated or manual assembly. Bulk packaging supplies loose components in containers, suitable for manual assembly or kitting operations. All three formats contain identical components.

Q: Are there compliance differences between the substitute parts?

A: Yes. CW01020K00JS733 is RoHS non-compliant and REACH Affected. CW01020K00JE12 and CW01020K00JE73 are both ROHS3 Compliant and REACH Unaffected. Applications requiring RoHS3 compliance must use CW01020K00JE12 or CW01020K00JE73.

Q: Which substitute has the best inventory availability?

A: CW01020K00JE73 in Cut Tape format has the highest inventory with 2271 units in stock, compared to 973 units for CW01020K00JE12 (Bulk) and 1055 units for the original CW01020K00JS733 (Tape & Reel).

Q: Do the substitutes maintain the same moisture-resistant features?

A: Yes. All three parts feature moisture-resistant construction and are suitable for applications requiring protection against moisture ingress.
