Key Parameters

Substitute Part Grouping Explanation

The CW01025R00JE73 qualifies as a direct substitute for the CW01025R00JS73 based on the following critical parameters:

All electrical specifications are identical: 25 Ohms resistance, ±5% tolerance, 13W power rating, ±30ppm/°C temperature coefficient, and -65°C to 350°C operating temperature range. The mechanical form factor is unchanged: axial package with 0.375" diameter and 1.781" length. Both parts feature moisture-resistant wirewound construction with two terminations.

The primary difference is packaging format: CW01025R00JS73 is supplied in Tape & Reel (TR), while CW01025R00JE73 is supplied in Cut Tape (CT). This distinction affects handling, storage, and automated assembly processes but does not impact electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both CW01025R00JS73 and CW01025R00JE73 are active production parts from Vishay Dale with identical electrical and mechanical specifications. Selection between these parts should be based on packaging requirements and regulatory compliance needs.

The CW01025R00JE73 offers improved compliance status: it is ROHS3 compliant and REACH unaffected, compared to the CW01025R00JS73 which is RoHS non-compliant and REACH affected. For applications subject to RoHS or REACH regulations, the CW01025R00JE73 is the appropriate choice.

Packaging format determines suitability for assembly processes. Tape & Reel (TR) packaging is optimized for high-volume automated pick-and-place assembly. Cut Tape (CT) packaging is suitable for lower-volume applications or manual assembly operations. Both formats contain the identical component.

Frequently Asked Questions (FAQ)

Q: Can CW01025R00JE73 be used as a direct replacement for CW01025R00JS73?

A: Yes. Both parts are electrically and mechanically identical. The CW01025R00JE73 differs only in packaging format (Cut Tape versus Tape & Reel) and offers superior compliance status (ROHS3 compliant, REACH unaffected).

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

A: Tape & Reel (TR) packaging supplies components on a continuous reel suitable for automated assembly equipment. Cut Tape (CT) packaging supplies components on tape segments, typically used for lower-volume or manual assembly applications. The components themselves are identical.

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

A: No. Both parts have identical resistance (25 Ohms), tolerance (±5%), power rating (13W), temperature coefficient (±30ppm/°C), and operating temperature range (-65°C to 350°C).

Q: Which part should I select for RoHS-compliant applications?

A: The CW01025R00JE73 is ROHS3 compliant and should be selected for applications requiring RoHS compliance. The CW01025R00JS73 is RoHS non-compliant.

Q: Do these parts have the same physical dimensions?

A: Yes. Both parts are 0.375" diameter by 1.781" length (9.52mm x 45.24mm) in axial package configuration.

Q: What inventory levels are available?

A: CW01025R00JS73 has 999 pieces in stock. CW01025R00JE73 has 1810 pieces in stock.
