Substitute Part Grouping Explanation

The WW5JT4R00 qualifies as a direct substitute for the WW5JB4R00 based on identical electrical and mechanical parameters. Both parts share the same resistance value (4 Ohms), tolerance (±5%), power rating (5W), wirewound composition, axial package configuration, physical dimensions (0.312" Dia x 0.875" L), temperature coefficient (±50ppm/°C), operating temperature range (-55°C ~ 350°C), moisture-resistant features, and regulatory compliance (ROHS3 Compliant, REACH Unaffected). The substitution is valid across all functional and environmental criteria. The primary distinction between these parts is packaging format: WW5JB4R00 is supplied in Bulk packaging, while WW5JT4R00 is supplied in Cut Tape (CT) packaging. This packaging difference does not affect electrical performance or mechanical compatibility in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both WW5JB4R00 and WW5JT4R00 maintain Active product status with full ROHS3 compliance and REACH unaffected classification. Selection between these parts should be based on packaging requirements and supply chain logistics. The WW5JB4R00 in Bulk packaging is suitable for high-volume manufacturing environments with automated handling systems. The WW5JT4R00 in Cut Tape (CT) packaging is appropriate for pick-and-place assembly operations and lower-volume production runs. Both parts deliver identical electrical performance and environmental reliability across the specified operating temperature range of -55°C to 350°C.

Frequently Asked Questions (FAQ)

Q: Can WW5JT4R00 replace WW5JB4R00 in circuit applications? A: Yes. Both parts are electrically and mechanically identical. The WW5JT4R00 functions as a direct substitute with no performance differences in circuit operation.

Q: What is the difference between Bulk and Cut Tape (CT) packaging? A: Bulk packaging supplies loose components suitable for manual assembly or bulk handling. Cut Tape (CT) packaging provides components on continuous tape in standardized quantities, optimized for automated pick-and-place assembly equipment.

Q: Are the physical dimensions identical between these parts? A: Yes. Both parts measure 0.312" diameter by 0.875" length (7.92mm x 22.23mm) and fit identical PCB footprints and through-hole spacing.

Q: Do both parts meet the same regulatory requirements? A: Yes. Both WW5JB4R00 and WW5JT4R00 are ROHS3 compliant and REACH unaffected, meeting identical environmental and regulatory standards.

Q: Is the temperature coefficient the same for both parts? A: Yes. Both parts have a temperature coefficient of ±50ppm/°C and operate across the identical temperature range of -55°C to 350°C.

Q: Can these parts be used interchangeably in high-reliability applications? A: Yes. Both parts carry Active product status from Stackpole Electronics Inc and maintain identical moisture-resistant wirewound construction, making them suitable for equivalent reliability requirements.
