Substitute Part Grouping Explanation

Substitution for the CW005250R0JS73 is determined by electrical and mechanical parameter equivalence within the Vishay Dale CW series. The substitute part CW005250R0JE73 maintains identical electrical specifications: 250 Ohms resistance, ±5% tolerance, 6.5W power rating, wirewound composition, and moisture-resistant features. Both parts share the same axial package configuration and physical dimensions (0.312" Dia x 0.875" L). The primary difference between these parts is packaging format: the main part is supplied in Tape & Reel (TR) configuration, while the substitute is supplied in Cut Tape (CT) configuration. Both parts operate across the same temperature range (-65°C ~ 350°C) with identical temperature coefficient (±30ppm/°C). The substitute part differs in RoHS compliance status and REACH classification, which may be relevant for specific regulatory requirements.

Parameter Comparison

Engineering Selection Recommendations

Both CW005250R0JS73 and CW005250R0JE73 are Active status components from Vishay Dale with identical electrical and mechanical specifications. Selection between these parts should be based on the following factors:

Packaging format requirements determine primary selection. The CW005250R0JS73 in Tape & Reel format is suitable for automated assembly processes requiring continuous reel feeding. The CW005250R0JE73 in Cut Tape format is appropriate for manual assembly, small-batch production, or applications where reel handling is not required.

Regulatory compliance requirements may influence selection. The CW005250R0JE73 carries ROHS3 compliance certification, making it the appropriate choice for applications subject to RoHS3 regulatory requirements. The CW005250R0JS73 is RoHS non-compliant and REACH Affected, which may restrict its use in certain jurisdictions or applications with strict environmental compliance mandates.

Both parts share identical electrical performance characteristics and physical dimensions, ensuring functional interchangeability in circuit design. The choice between these parts does not affect circuit performance, thermal characteristics, or reliability within the specified operating temperature range of -65°C to 350°C.

Frequently Asked Questions (FAQ)

Q: Are CW005250R0JS73 and CW005250R0JE73 electrically identical?

A: Yes. Both parts have identical resistance (250 Ohms), tolerance (±5%), power rating (6.5W), temperature coefficient (±30ppm/°C), and operating temperature range (-65°C ~ 350°C). They are electrically equivalent and will perform identically in circuit applications.

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

A: Tape & Reel (TR) packaging supplies components on continuous reels suitable for automated pick-and-place assembly equipment. Cut Tape (CT) packaging provides individual components or small quantities cut from tape, suitable for manual assembly or low-volume production. Both formats contain the same component with identical specifications.

Q: Can I use CW005250R0JE73 as a direct replacement for CW005250R0JS73?

A: Yes, from an electrical and mechanical standpoint, CW005250R0JE73 is a direct substitute. However, packaging format compatibility with your assembly process must be confirmed. If your production line requires Tape & Reel format, Cut Tape packaging may require process modification.

Q: Why does CW005250R0JE73 have ROHS3 compliance while CW005250R0JS73 does not?

A: RoHS compliance status is determined by manufacturing processes and material composition. CW005250R0JE73 meets ROHS3 standards, while CW005250R0JS73 does not. For applications requiring RoHS3 certification, CW005250R0JE73 is the appropriate selection.

Q: Are the physical dimensions identical between these two parts?

A: Yes. Both parts have identical axial package dimensions of 0.312" Dia x 0.875" L (7.92mm x 22.22mm), ensuring identical PCB footprint and mounting requirements.

Q: Which part should I select for new designs?

A: Selection depends on your specific requirements. For automated assembly with Tape & Reel capability, use CW005250R0JS73. For applications requiring ROHS3 compliance or using Cut Tape packaging, use CW005250R0JE73. Both are Active status components suitable for new designs.
