Engineering Selection Recommendations

The CW010500R0JE73 serves as a direct functional equivalent to the CW010500R0JS73. Selection between these parts should be based on the following criteria:

CW010500R0JS73 (Tape & Reel): Suitable for high-volume automated assembly operations where components are supplied in continuous tape format. Current inventory: 1103 pieces.

CW010500R0JE73 (Cut Tape): Appropriate for lower-volume applications, manual assembly processes, or situations where individual component handling is required. This variant offers ROHS3 compliance and REACH unaffected status, making it preferable for applications subject to environmental regulations. Current inventory: 1495 pieces.

Both parts maintain identical electrical performance and physical dimensions. The choice between packaging formats depends on assembly methodology and regulatory requirements specific to the end application.

Frequently Asked Questions (FAQ)

Q: Are CW010500R0JS73 and CW010500R0JE73 electrically identical?

A: Yes. Both parts have identical resistance (500 Ohms), tolerance (±5%), power rating (13W), temperature coefficient (±30ppm/°C), and operating temperature range (-65°C to 350°C). They are functionally interchangeable in circuit applications.

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

A: Tape & Reel (TR) packaging supplies components in a continuous reel format, optimized for automated pick-and-place assembly. Cut Tape (CT) packaging provides individual components or small quantities cut from tape, suitable for manual assembly or low-volume production.

Q: Can I use CW010500R0JE73 as a direct replacement for CW010500R0JS73?

A: Yes, provided your assembly process accommodates Cut Tape format. The electrical and mechanical specifications are identical, and both parts fit the same PCB footprint.

Q: What is the significance of RoHS and REACH compliance differences?

A: CW010500R0JE73 is ROHS3 compliant and REACH unaffected, making it suitable for applications in regions with strict environmental regulations. CW010500R0JS73 is RoHS non-compliant and REACH affected. Compliance requirements depend on the end-use application and target market.

Q: Are the physical dimensions identical?

A: Yes. Both parts measure 0.375" diameter by 1.781" length (9.52mm x 45.24mm), ensuring identical PCB mounting and thermal characteristics.

Q: Which part should I select for new designs?

A: Selection depends on assembly capability and regulatory requirements. For automated assembly with no environmental compliance constraints, either part is acceptable. For new designs subject to RoHS or REACH regulations, CW010500R0JE73 is the appropriate choice.
