Substitute Part Grouping Explanation

Substitute parts for the CW01050R00JS733 are qualified based on identical electrical and mechanical parameters: 50 Ohm resistance value, ±5% tolerance, 13W power rating, wirewound composition, axial package configuration, ±30ppm/°C temperature coefficient, -65°C to 350°C operating temperature range, and matching physical dimensions of 0.375" Dia x 1.781" L.

The substitute parts differ only in packaging format (Tape & Reel, Bulk, or Cut Tape) and compliance certifications (RoHS and REACH status). These variations do not affect electrical or mechanical performance and allow selection based on procurement, inventory, and regulatory requirements.

Parameter Comparison

Engineering Selection Recommendations

All three parts—CW01050R00JS733, CW01050R00JE12, and CW01050R00JE73—are electrically and mechanically identical and interchangeable in circuit applications. Selection between them is determined by packaging requirements and regulatory compliance needs.

CW01050R00JE12 and CW01050R00JE73 are ROHS3 compliant and REACH unaffected, making them suitable for applications subject to European Union environmental regulations. CW01050R00JS733 is RoHS non-compliant and REACH affected, appropriate for applications without such regulatory constraints.

Packaging format selection depends on assembly process requirements: Tape & Reel (TR) for automated pick-and-place assembly, Bulk for manual assembly or kit applications, and Cut Tape (CT) for mixed-volume procurement. CW01050R00JE73 offers the highest inventory availability at 2314 units.

Frequently Asked Questions (FAQ)

Q: Are these parts electrically interchangeable? A: Yes. CW01050R00JS733, CW01050R00JE12, and CW01050R00JE73 share identical electrical specifications: 50 Ohm resistance, ±5% tolerance, 13W power rating, ±30ppm/°C temperature coefficient, and -65°C to 350°C operating range. They are direct functional equivalents.

Q: What is the difference between these part numbers? A: The parts differ in packaging format and compliance certifications. CW01050R00JS733 is supplied in Tape & Reel format and is RoHS non-compliant. CW01050R00JE12 is supplied in Bulk format with ROHS3 compliance. CW01050R00JE73 is supplied in Cut Tape format with ROHS3 compliance. All other specifications are identical.

Q: Which packaging format should I select? A: Tape & Reel (TR) is standard for high-volume automated assembly. Bulk packaging suits manual assembly or component kits. Cut Tape (CT) provides flexibility for mixed-volume orders. Physical dimensions and mounting characteristics are identical across all formats.

Q: Are there compliance differences I should consider? A: CW01050R00JE12 and CW01050R00JE73 are ROHS3 compliant and REACH unaffected, meeting European Union environmental standards. CW01050R00JS733 is RoHS non-compliant and REACH affected. Select based on your application's regulatory requirements.

Q: Can I substitute CW01050R00JS733 with CW01050R00JE73 in my design? A: Yes, provided your application does not require RoHS or REACH compliance. If compliance is required, CW01050R00JE73 is the appropriate selection. Electrical and mechanical performance are identical.
