Parameter Comparison

Engineering Selection Recommendations

Both the Vishay Spectrol 533B1502JC and Bourns Inc. 3547S-1AA-502A are actively manufactured components with RoHS3 compliance, making them suitable for current production environments. The Bourns substitute offers a tighter tolerance specification (±3% versus ±5%), which may provide improved precision in applications requiring closer resistance control. Both components carry identical ECCN and HTSUS classifications, ensuring consistent regulatory and trade compliance. Physical dimensions are nominally equivalent, with body diameter differences of 0.01" (0.25mm), which is negligible for standard panel mount applications. Selection between these parts should be based on procurement availability, cost considerations, and specific tolerance requirements of the application.

Frequently Asked Questions (FAQ)

Q: Can the Bourns 3547S-1AA-502A directly replace the Vishay Spectrol 533B1502JC in existing designs?

A: Yes. Both components share identical electrical specifications (5k Ohm, 1W, linear taper, 3-turn wirewound), mechanical mounting parameters (3/8-32 bushing thread, panel mount), and termination style (solder lug). Physical dimensions are nominally equivalent for standard panel applications.

Q: What are the tolerance differences between these parts?

A: The Vishay Spectrol 533B1502JC has a tolerance of ±5%, while the Bourns 3547S-1AA-502A offers ±3%. The Bourns substitute provides tighter tolerance control, which may be advantageous in precision applications.

Q: Are there packaging differences between these substitutes?

A: Yes. The Vishay Spectrol 533B1502JC is supplied in Bulk packaging, while the Bourns 3547S-1AA-502A is supplied in Tray packaging. Packaging selection should align with your procurement and assembly workflow requirements.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both components are RoHS3 compliant and carry identical ECCN (EAR99) and HTSUS (8533.31.0000) classifications, ensuring regulatory alignment for current production.

Q: What is the temperature coefficient difference?

A: The Vishay Spectrol 533B1502JC has a temperature coefficient of 20ppm/°C, while the Bourns 3547S-1AA-502A is specified at ±50ppm/°C. For applications operating across wide temperature ranges, the Vishay component offers superior temperature stability.
