Substitute Part Grouping Explanation

Substitution eligibility for the CW01012R00JS733 is determined by strict equivalence across the following critical parameters:

• Resistance value: 12 Ohms
• Tolerance: ±5%
• Power rating: 13W
• Composition: Wirewound
• Package type: Axial
• Physical dimensions: 0.375" Dia x 1.781" L (9.52mm x 45.24mm)
• Temperature coefficient: ±30ppm/°C
• Operating temperature range: -65°C ~ 350°C
• Moisture-resistant feature requirement

The CW01012R00JE12 meets all electrical and mechanical specifications required for direct substitution. The primary difference between these parts is packaging format: the main part is supplied in Tape & Reel format, while the substitute is supplied in Bulk packaging.

Parameter Comparison

Engineering Selection Recommendations

Both CW01012R00JS733 and CW01012R00JE12 are electrically and mechanically equivalent 12 Ohm, 13W axial wirewound resistors from Vishay Dale's active product line. Selection between these parts should be based on the following factors:

CW01012R00JS733 is appropriate when Tape & Reel packaging is required for automated assembly processes or when specific supply chain requirements mandate this format.

CW01012R00JE12 is appropriate when Bulk packaging is acceptable and when ROHS3 compliance and REACH unaffected status are required for the application. This part offers improved regulatory compliance compared to the main part number.

Both parts share identical electrical performance, thermal characteristics, and physical dimensions, ensuring functional interchangeability in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can CW01012R00JE12 be used as a direct replacement for CW01012R00JS733?

A: Yes. Both parts are electrically and mechanically identical 12 Ohm, 13W axial wirewound resistors with the same physical dimensions, tolerance, temperature coefficient, and operating range. The only differences are packaging format and regulatory compliance status.

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

A: Tape & Reel packaging is designed for automated pick-and-place assembly equipment and provides components in a continuous tape format. Bulk packaging supplies components in loose form. Selection depends on assembly process requirements.

Q: Does the CW01012R00JE12 have better compliance than CW01012R00JS733?

A: Yes. CW01012R00JE12 is ROHS3 compliant and REACH unaffected, while CW01012R00JS733 is RoHS non-compliant and REACH affected. Applications with regulatory compliance requirements should specify CW01012R00JE12.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts measure 0.375" diameter by 1.781" length (9.52mm x 45.24mm) and are housed in identical axial packages with two terminations.

Q: Can these parts be used interchangeably in high-temperature applications?

A: Yes. Both parts operate across the same temperature range of -65°C to 350°C with identical temperature coefficient specifications of ±30ppm/°C.
