Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PRF18BE471RS5RB are qualified based on the following criteria:

Electrical Compatibility: All substitute parts maintain 470 Ohms resistance at 25°C with ±50% tolerance, ensuring functional equivalence in circuit operation.

Mechanical Compatibility: All substitute parts use the 0603 (1608 Metric) surface mount package, enabling direct PCB footprint compatibility without layout modifications.

Environmental Specifications: Substitute parts from EPCOS - TDK Electronics (B59601 and B59641 series) operate across -40°C to 125°C, which encompasses the PRF18BE471RS5RB operating range of -20°C to 110°C.

Regulatory Compliance: All substitute parts maintain ROHS3 compliance, MSL 1 rating, and REACH unaffected status, matching the original part's compliance profile.

Packaging Options: Substitute parts are available in Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel® formats, supporting different procurement and assembly workflows.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active product status and full ROHS3 compliance with MSL 1 rating. The EPCOS - TDK Electronics B59601 series provides direct electrical and mechanical equivalence with extended operating temperature range (-40°C to 125°C), supporting applications requiring broader thermal performance margins. The B59641A0105A062 variant includes AEC-Q200 automotive qualification, suitable for applications requiring automotive-grade component certification. Selection between standard B59601 variants and the B59641 automotive-qualified option depends on application requirements and qualification standards. Packaging format selection (Tape & Reel or Cut Tape & Digi-Reel®) should align with assembly process requirements and procurement workflows.

Frequently Asked Questions (FAQ)

Q: Can B59601 series parts directly replace the PRF18BE471RS5RB?

A: Yes. The B59601 series maintains identical electrical specifications (470 Ohms, ±50% tolerance) and mechanical compatibility (0603 package, surface mount). The extended operating temperature range (-40°C to 125°C) encompasses the original part's -20°C to 110°C specification.

Q: What is the difference between B59601 and B59641 series?

A: The B59641A0105A062 includes AEC-Q200 automotive qualification and automotive-grade designation. Both series share identical electrical and mechanical specifications. Selection depends on whether automotive qualification is required for the application.

Q: Are packaging format differences significant for substitution?

A: Packaging format (Tape & Reel vs. Cut Tape & Digi-Reel®) affects procurement and assembly logistics but does not impact electrical or mechanical compatibility. Component selection should align with existing assembly equipment and supply chain processes.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. All substitute parts maintain ROHS3 compliance, MSL 1 (Unlimited) rating, and REACH unaffected status, matching the original PRF18BE471RS5RB compliance profile.

Q: Is the 0603 package footprint identical across all parts?

A: Yes. All parts use the 0603 (1608 Metric) surface mount package, enabling direct PCB footprint compatibility without layout modifications or rework.
