Key Parameters

Substitute Part Grouping Explanation

The CW01027R00JE73HE qualifies as a parametric equivalent based on the following critical electrical and mechanical parameters:

• Resistance value: 27 Ohms (identical)
• Tolerance: ±5% (identical)
• Power rating: 13W (identical)
• Composition: Wirewound (identical)
• Package type: Axial (identical)
• Temperature coefficient: ±30ppm/°C (identical)
• Operating temperature range: -65°C to 350°C (identical)
• Physical dimensions: 0.375" Dia x 1.781" L (identical)
• Termination count: 2 (identical)

The primary difference between these parts is packaging format: the main part is supplied in Tape & Reel (TR) configuration, while the substitute is supplied in Cut Tape (CT) configuration. Both are manufactured by Vishay Dale within the same CW series.

Parameter Comparison

Engineering Selection Recommendations

Both parts are active products from Vishay Dale with identical electrical and mechanical specifications. Selection between these parts should be based on the following factors:

The CW01027R00JE73HE offers improved regulatory compliance, meeting ROHS3 requirements and REACH unaffected status, making it suitable for applications with strict environmental and regulatory constraints. The CW01027R00JS73 is available in Tape & Reel packaging, which is standard for high-volume automated assembly operations. The CW01027R00JE73HE in Cut Tape format is appropriate for lower-volume applications or manual assembly processes. Inventory availability differs between the two configurations, with the Cut Tape variant currently showing higher stock levels at 1255 units.

Frequently Asked Questions (FAQ)

Q: Are these parts electrically interchangeable?

A: Yes. Both parts have identical resistance values (27 Ohms), tolerance (±5%), power rating (13W), temperature coefficient (±30ppm/°C), and operating temperature range (-65°C to 350°C). They are electrically equivalent for all circuit applications.

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

A: Tape & Reel (TR) packaging supplies components on continuous tape wound on reels, optimized for automated pick-and-place assembly. Cut Tape (CT) packaging supplies components on tape segments cut to specific lengths, suitable for manual assembly or lower-volume production runs.

Q: Can I use the Cut Tape version in place of the Tape & Reel version?

A: Yes, provided your assembly process can accommodate Cut Tape format. The electrical and mechanical specifications are identical. Verify that your assembly equipment or manual handling procedures are compatible with the Cut Tape format before substitution.

Q: What are the regulatory compliance differences?

A: The CW01027R00JE73HE is ROHS3 compliant and REACH unaffected, while the CW01027R00JS73 is RoHS non-compliant and REACH affected. For applications subject to environmental regulations, the CW01027R00JE73HE is the appropriate selection.

Q: Are the physical dimensions identical?

A: Yes. Both parts measure 0.375" diameter by 1.781" length (9.52mm x 45.24mm). They are mechanically interchangeable in terms of board layout and mounting requirements.

Q: Which part should I select for new designs?

A: Selection depends on assembly capability and regulatory requirements. For automated assembly with regulatory compliance needs, use CW01027R00JE73HE. For manual assembly or existing designs already qualified on the TR format, CW01027R00JS73 remains valid.
