Substitute Part Grouping Explanation

The CW01047R00JE12 qualifies as a direct substitute for the CW01047R00JS733 based on identical electrical and mechanical specifications. Both parts share the same resistance value (47 Ohms), tolerance (±5%), power rating (13W), wirewound composition, temperature coefficient (±30ppm/°C), operating temperature range (-65°C to 350°C), axial package configuration, and physical dimensions (0.375" Dia x 1.781" L). The primary difference is packaging format: CW01047R00JS733 is supplied in tape and reel configuration, while CW01047R00JE12 is supplied in bulk packaging. Additionally, CW01047R00JE12 achieves ROHS3 compliance and REACH unaffected status, whereas the main part is RoHS non-compliant and REACH affected.

Parameter Comparison

Engineering Selection Recommendations

Select CW01047R00JS733 when tape and reel packaging is required for automated assembly processes. This configuration is standard for high-volume production environments utilizing pick-and-place equipment.

Select CW01047R00JE12 when bulk packaging is acceptable and regulatory compliance with ROHS3 and REACH unaffected status is required. This variant is suitable for applications subject to European Union environmental directives and RoHS regulations.

Both parts are functionally equivalent for applications requiring 47 Ohm, 13W wirewound axial resistors with moisture-resistant construction and wide temperature range operation. The choice between them depends on packaging requirements and regulatory compliance mandates specific to the end application and target market.

Frequently Asked Questions (FAQ)

Q: Are CW01047R00JS733 and CW01047R00JE12 electrically identical?

A: Yes. Both parts have identical electrical specifications: 47 Ohms resistance, ±5% tolerance, 13W power rating, ±30ppm/°C temperature coefficient, and -65°C to 350°C operating temperature range.

Q: What is the difference between tape and reel and bulk packaging?

A: Tape and reel packaging (CW01047R00JS733) supplies components on continuous carrier tape wound on reels, designed for automated assembly equipment. Bulk packaging (CW01047R00JE12) supplies loose components in containers, suitable for manual assembly or lower-volume applications.

Q: Can CW01047R00JE12 replace CW01047R00JS733 in automated assembly?

A: CW01047R00JE12 bulk packaging is not compatible with standard tape-and-reel fed pick-and-place equipment. Use CW01047R00JS733 for automated assembly processes.

Q: What are the compliance differences between these parts?

A: CW01047R00JS733 is RoHS non-compliant and REACH affected. CW01047R00JE12 is ROHS3 compliant and REACH unaffected, making it suitable for applications requiring European Union environmental compliance.

Q: Are the physical dimensions identical?

A: Yes. Both parts have identical axial package dimensions of 0.375" diameter by 1.781" length (9.52mm x 45.24mm).

Q: Which part should I select for new designs?

A: For new designs subject to RoHS and REACH regulations, CW01047R00JE12 is the appropriate selection. For legacy designs or applications without regulatory compliance requirements, either part is functionally suitable based on packaging needs.
