Substitute Part Grouping Explanation

Substitution eligibility for the CW01027K00JS73 is determined by strict equivalence across all electrical and mechanical parameters. The primary differentiator between the main part and identified substitutes is packaging format. Both the main part (CW01027K00JS73) and substitute part (CW01027K00JB12) maintain identical specifications for resistance value, tolerance, power rating, composition, physical dimensions, temperature coefficient, and operating temperature range. The substitution is valid because packaging format (Tape & Reel versus Bulk) does not affect component performance or board-level compatibility in axial through-hole applications. All parts belong to the Vishay Dale CW series and share the same core construction and performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both CW01027K00JS73 and CW01027K00JB12 are active production parts from Vishay Dale with identical electrical and mechanical specifications. Selection between these parts should be based on procurement and assembly requirements. The CW01027K00JS73 in Tape & Reel packaging is suitable for automated assembly processes and high-volume production environments. The CW01027K00JB12 in Bulk packaging accommodates manual assembly, prototype builds, or applications where reel packaging is not required. Both parts carry RoHS non-compliant status and REACH Affected designation. Neither part introduces compliance or performance trade-offs when substituted for the other in equivalent applications.

Frequently Asked Questions (FAQ)

Q: Can CW01027K00JB12 be used as a direct replacement for CW01027K00JS73?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (Bulk versus Tape & Reel). Substitution is valid for any application where the CW01027K00JS73 is specified, provided assembly equipment can accommodate the alternative packaging format.

Q: What is the significance of the packaging difference between these parts?

A: Tape & Reel (TR) packaging is optimized for automated pick-and-place assembly systems used in high-volume manufacturing. Bulk packaging is used for manual assembly, kit builds, or lower-volume applications. The component itself performs identically regardless of packaging format.

Q: Are there any compliance differences between the substitute parts?

A: No. Both parts share identical RoHS status (non-compliant), REACH status (Affected), ECCN (EAR99), and HTSUS classification (8533.21.0080).

Q: What parameters must remain constant for substitution validity?

A: Resistance value (27 kOhms), tolerance (±5%), power rating (13W), composition (Wirewound), physical dimensions (0.375" Dia x 1.781" L), temperature coefficient (±30ppm/°C), operating temperature range (-65°C ~ 350°C), and moisture-resistant features must all remain unchanged. Packaging format is the only variable parameter.

Q: Is inventory availability a factor in substitution decisions?

A: Inventory levels are provided for reference but do not affect technical substitution validity. Both parts are active production items. Procurement decisions should account for lead times and availability through authorized distributors.
