Key Parameters

Substitute Part Grouping Explanation

Substitution for the CW010120R0JS73 is determined by equivalence across the following critical parameters:

• Resistance value: 120 Ohms
• Tolerance: ±5%
• Power rating: 13W
• Composition: Wirewound
• Package case: Axial
• Physical dimensions: 0.375" Dia x 1.781" L
• Temperature coefficient: ±30ppm/°C
• Operating temperature range: -65°C ~ 350°C
• Moisture resistance feature

The primary difference between the main part and its substitute is the packaging format (Tape & Reel versus Cut Tape) and compliance certifications. Both parts are manufactured by Vishay Dale within the CW series and maintain identical electrical and mechanical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The CW010120R0JS73 and CW010120R0JE73 are electrically and mechanically equivalent. Selection between these parts should be based on:

Packaging format requirements: The CW010120R0JS73 is supplied in Tape & Reel format, suitable for automated assembly processes. The CW010120R0JE73 is supplied in Cut Tape format, suitable for manual or lower-volume assembly operations.

Compliance requirements: The CW010120R0JE73 is ROHS3 compliant and REACH unaffected, making it the appropriate choice for applications subject to these regulatory frameworks. The CW010120R0JS73 is RoHS non-compliant and REACH affected.

Inventory availability: Current stock levels differ between formats. The CW010120R0JE73 has higher inventory availability (1576 pcs) compared to the CW010120R0JS73 (777 pcs).

Frequently Asked Questions (FAQ)

Q: Are CW010120R0JS73 and CW010120R0JE73 electrically identical?

A: Yes. Both parts have identical resistance (120 Ohms), tolerance (±5%), power rating (13W), temperature coefficient (±30ppm/°C), and operating temperature range (-65°C ~ 350°C).

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

A: Tape & Reel packaging is used for high-volume automated assembly, where components are fed directly into pick-and-place machines. Cut Tape packaging consists of individual component strips and is used for manual assembly or lower-volume production runs.

Q: Can I use CW010120R0JE73 as a direct replacement for CW010120R0JS73?

A: Yes, provided your assembly process accommodates Cut Tape packaging format. The electrical and mechanical specifications are identical.

Q: What does ROHS3 compliance mean?

A: ROHS3 compliance indicates the part meets the Restriction of Hazardous Substances Directive 3, restricting the use of specific hazardous materials in electrical and electronic equipment.

Q: Does the physical size differ between these parts?

A: No. Both parts have identical dimensions: 0.375" Dia x 1.781" L (9.52mm x 45.24mm).

Q: Which part should I select for new designs?

A: Selection depends on assembly capability and regulatory requirements. For automated assembly with regulatory compliance needs, use CW010120R0JE73. For manual assembly or legacy systems without compliance constraints, either part is suitable based on packaging availability.
