CW00550R00JS73 Equivalent & Substitute Parts

Part Overview

The CW00550R00JS73 is a 50 Ohm, 6.5W wirewound axial resistor manufactured by Vishay Dale. This through-hole component features moisture-resistant construction and operates across a wide temperature range from -65°C to 350°C. The part is currently active in production with 921 units available in tape and reel packaging.

Substitute parts become necessary when tape and reel packaging is unavailable or when alternative compliance certifications are required for specific applications. The CW00550R00JE73 provides an electrically and mechanically equivalent alternative with different packaging and compliance characteristics.

Substitute Part Grouping Explanation

Substitution between CW00550R00JS73 and CW00550R00JE73 is valid based on the following criteria:

Electrical Parameters (Identical):

• Resistance value: 50 Ohms
• Tolerance: ±5%
• Power rating: 6.5W
• Temperature coefficient: ±30ppm/°C
• Operating temperature range: -65°C to 350°C

Mechanical Parameters (Identical):

• Package type: Axial
• Physical dimensions: 0.312" Dia x 0.875" L (7.92mm x 22.22mm)
• Number of terminations: 2
• Composition: Wirewound
• Features: Moisture Resistant

Packaging Difference:

• CW00550R00JS73: Tape & Reel (TR)
• CW00550R00JE73: Cut Tape (CT)

Both parts share identical electrical and mechanical specifications, making them functionally interchangeable in circuit applications. The primary distinction is packaging format and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both parts are active products from Vishay Dale with identical electrical and mechanical specifications. Selection between them depends on specific application requirements:

CW00550R00JS73 (Tape & Reel) is suitable for high-volume automated assembly processes where tape and reel packaging is required for pick-and-place equipment.

CW00550R00JE73 (Cut Tape) is suitable for applications requiring ROHS3 compliance and REACH unaffected status. This part also offers higher inventory availability (1639 units versus 921 units) and is compatible with manual assembly or lower-volume production workflows.

For applications with regulatory requirements mandating RoHS3 compliance or REACH unaffected status, CW00550R00JE73 is the appropriate selection. For high-volume manufacturing requiring tape and reel format, CW00550R00JS73 remains the primary choice.

Frequently Asked Questions (FAQ)

Q: Are these parts electrically identical? A: Yes. Both parts have identical resistance (50 Ohms), tolerance (±5%), power rating (6.5W), temperature coefficient (±30ppm/°C), and operating temperature range (-65°C to 350°C).

Q: What is the difference between these parts? A: The primary differences are packaging format (Tape & Reel versus Cut Tape) and compliance certifications. CW00550R00JE73 is ROHS3 compliant and REACH unaffected, while CW00550R00JS73 is RoHS non-compliant and REACH affected.

Q: Can I use CW00550R00JE73 in place of CW00550R00JS73? A: Yes, provided your assembly process can accommodate cut tape packaging instead of tape and reel format, and your application does not require the specific compliance profile of the original part.

Q: Can I use CW00550R00JS73 in place of CW00550R00JE73? A: Only if your application does not have RoHS3 compliance or REACH unaffected requirements. The electrical and mechanical specifications are identical.

Q: Are the physical dimensions identical? A: Yes. Both parts have identical axial package dimensions of 0.312" Dia x 0.875" L (7.92mm x 22.22mm) and will fit the same PCB footprint.

Q: Which part should I choose for new designs? A: Selection depends on your manufacturing process and regulatory requirements. For automated high-volume assembly, use CW00550R00JS73. For applications requiring RoHS3 compliance or REACH unaffected status, use CW00550R00JE73.
