Substitute Part Grouping Explanation

Substitution of the 604HR010 is based on strict equivalence across all critical electrical and mechanical parameters: resistance value (10 mOhms), tolerance (±3%), power rating (0.375W), composition (metal element), package configuration (axial), and physical dimensions (0.250" L). The substitute part must maintain identical functional characteristics for current sense applications while meeting the same safety and performance standards.

The 604HR010E qualifies as a direct substitute because it matches all specified parameters without deviation. The primary distinction is product status: the 604HR010 is obsolete, while the 604HR010E is active, and RoHS compliance status differs (604HR010 is non-compliant; 604HR010E is ROHS3 compliant).

Parameter Comparison

Engineering Selection Recommendations

The 604HR010E is the direct functional equivalent of the 604HR010. Selection of the 604HR010E is appropriate for applications requiring active component availability and RoHS3 compliance. The 604HR010E maintains identical electrical performance and mechanical compatibility while offering improved regulatory compliance status and current production availability.

For applications with RoHS non-compliance requirements or legacy system constraints, the 604HR010 remains available in existing inventory. However, the transition to 604HR010E is recommended for new designs and ongoing production due to active product status and regulatory alignment.

Frequently Asked Questions (FAQ)

Q: Can the 604HR010E replace the 604HR010 in existing designs? A: Yes. The 604HR010E is electrically and mechanically identical to the 604HR010. All parameters—resistance, tolerance, power rating, composition, package type, and physical dimensions—are equivalent. Direct substitution is valid.

Q: What is the difference between the 604HR010 and 604HR010E? A: The primary differences are product status (604HR010 is obsolete; 604HR010E is active) and RoHS compliance (604HR010 is non-compliant; 604HR010E is ROHS3 compliant). Packaging differs (standard versus bulk), but electrical and mechanical specifications are identical.

Q: Are there any compatibility concerns when switching from 604HR010 to 604HR010E? A: No compatibility concerns exist. Both parts share identical axial package configuration, 0.250" length, 2-pin termination, and all functional characteristics. PCB layout and circuit integration remain unchanged.

Q: Why is the 604HR010 listed as obsolete? A: The 604HR010 has been superseded by the 604HR010E, which offers improved regulatory compliance and active manufacturing status. Ohmite continues to support the 604HR010E as the current production equivalent.

Q: What applications are these resistors suitable for? A: These metal element axial resistors are designed for current sense applications requiring flame-proof, non-inductive characteristics with safety ratings. The 10 mOhms resistance and 0.375W power rating support precision current measurement in industrial and safety-critical circuits.
