Substitute Part Grouping Explanation

The CW01050R00JE73 qualifies as a parametric equivalent to the CW01050R00JS70 based on the following criteria:

All critical electrical parameters are identical: 50 Ohm resistance, ±5% tolerance, 13W power rating, ±30ppm/°C temperature coefficient, and -65°C to 350°C operating temperature range. The mechanical specifications match exactly: axial package configuration, 0.375" diameter by 1.781" length, and two terminations. Both parts utilize wirewound composition with moisture-resistant features.

The primary difference between these parts is packaging format: CW01050R00JS70 is supplied in Tape & Reel (TR) configuration, while CW01050R00JE73 is supplied in Cut Tape (CT) configuration. This distinction affects inventory management and automated assembly processes but does not alter component functionality or performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both CW01050R00JS70 and CW01050R00JE73 are functionally equivalent for circuit applications requiring 50 Ohm, 13W axial wirewound resistors. Selection between these parts should be based on the following factors:

Packaging requirements determine primary selection criteria. Tape & Reel format (CW01050R00JS70) is suitable for high-volume automated assembly operations. Cut Tape format (CW01050R00JE73) accommodates lower-volume production runs or manual assembly processes.

Regulatory compliance status differs between the two parts. CW01050R00JE73 meets ROHS3 compliance requirements and is REACH unaffected, making it the appropriate choice for applications subject to European Union environmental regulations. CW01050R00JS70 is RoHS non-compliant and REACH affected, requiring evaluation against specific project compliance mandates.

Inventory availability favors CW01050R00JE73 with 2314 pieces in stock compared to 890 pieces for CW01050R00JS70, providing greater supply security for production schedules.

Frequently Asked Questions (FAQ)

Q: Can CW01050R00JE73 be used as a direct replacement for CW01050R00JS70 in circuit design?

A: Yes. Both parts maintain identical electrical specifications: 50 Ohm resistance, ±5% tolerance, 13W power rating, ±30ppm/°C temperature coefficient, and -65°C to 350°C operating temperature range. Mechanical dimensions and axial package configuration are identical. Substitution is valid from a functional standpoint.

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

A: Tape & Reel packaging supplies components on continuous carrier tape wound on a reel, optimized for automated pick-and-place assembly equipment. Cut Tape packaging supplies the same carrier tape in shorter segments, suitable for manual handling or lower-volume assembly processes. Both formats contain identical components.

Q: Does packaging format affect component performance?

A: No. Packaging format is a supply and handling consideration only. The resistor component itself, its electrical characteristics, and performance in circuit operation remain unchanged regardless of whether it arrives in Tape & Reel or Cut Tape format.

Q: Why does CW01050R00JE73 have better compliance status?

A: CW01050R00JE73 is manufactured to meet ROHS3 compliance standards and is REACH unaffected, indicating compliance with current European Union environmental directives. CW01050R00JS70 does not meet these standards. Compliance status reflects manufacturing process and material composition differences between production batches or manufacturing dates.

Q: Which part should be selected for new designs?

A: For new designs subject to EU environmental regulations or requiring ROHS3 compliance, CW01050R00JE73 is the appropriate selection. For applications without regulatory compliance requirements, either part is functionally suitable. Packaging format should align with assembly process capabilities.

Q: Are there any electrical performance differences between these parts?

A: No. Temperature coefficient, operating temperature range, tolerance, and all other electrical parameters are identical. Both parts are manufactured by Vishay Dale within the same CW series and deliver equivalent performance in circuit applications.
