Substitute Part Grouping Explanation

Substitution of CW0102K500JS73 with CW0102K500JE73 is valid based on identical electrical and mechanical parameters. Both parts share the same resistance value (2.5 kOhms), tolerance (±5%), power rating (13W), composition (wirewound), axial package configuration, physical dimensions (0.375" Dia x 1.781" L), temperature coefficient (±30ppm/°C), operating temperature range (-65°C ~ 350°C), and moisture-resistant features. The only difference between these parts is the packaging format: CW0102K500JS73 is supplied in Tape & Reel (TR) format, while CW0102K500JE73 is supplied in Cut Tape (CT) format. This distinction affects only the delivery and handling method, not the component's functional or mechanical characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both CW0102K500JS73 and CW0102K500JE73 are active production parts from Vishay Dale with identical electrical and mechanical specifications. Selection between these parts should be based on packaging requirements and regulatory compliance needs. The CW0102K500JE73 offers ROHS3 compliance, whereas the CW0102K500JS73 is RoHS non-compliant. For applications requiring RoHS3 compliance, CW0102K500JE73 is the appropriate selection. For applications with no RoHS compliance requirement, either part is functionally equivalent. Packaging format (Tape & Reel versus Cut Tape) should be selected based on assembly process requirements and inventory management practices.

Frequently Asked Questions (FAQ)

Q: Can CW0102K500JE73 be used as a direct replacement for CW0102K500JS73?

A: Yes. Both parts are electrically and mechanically identical with the same resistance (2.5 kOhms), tolerance (±5%), power rating (13W), physical dimensions (0.375" Dia x 1.781" L), and operating characteristics. The difference is packaging format only.

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

A: Tape & Reel (TR) packaging supplies components on a continuous reel suitable for automated pick-and-place assembly equipment. Cut Tape (CT) packaging supplies components on tape segments, typically used for manual assembly or lower-volume production runs. Both formats contain identical components.

Q: Does the RoHS compliance difference affect component performance?

A: No. RoHS compliance status reflects manufacturing process and material composition standards, not electrical or thermal performance. Both parts perform identically in circuit applications. RoHS3 compliance is a regulatory requirement for certain markets and applications.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts have identical axial package dimensions of 0.375" diameter by 1.781" length (9.52mm x 45.24mm), ensuring identical PCB footprint and mounting requirements.

Q: What is the temperature coefficient specification?

A: Both parts have a temperature coefficient of ±30ppm/°C, indicating resistance value change with temperature variation across the operating range of -65°C to 350°C.
