Key Parameters

Substitute Part Grouping Explanation

The 620HR005E qualifies as a direct substitute based on matching electrical and mechanical parameters. Substitution criteria are determined by the following parameters:

• Resistance value: 5 mOhms (exact match required)
• Tolerance: ±3% (exact match required)
• Power rating: 2W (exact match required)
• Composition: Metal Element (exact match required)
• Package: Axial (exact match required)
• Physical dimensions: 0.750" L (19.05mm) (exact match required)
• Functional features: Current Sense, Flame Proof, Non-Inductive, Safety (exact match required)

The 620HR005E maintains identical electrical specifications and physical form factor, enabling direct substitution in existing circuit designs.

Parameter Comparison

Engineering Selection Recommendations

The 620HR005E is the appropriate substitute for the obsolete 620HR005. Both parts are manufactured by Ohmite and share identical electrical and mechanical specifications. The primary distinction is product status: the 620HR005 is obsolete while the 620HR005E is active and currently in production.

The 620HR005E offers improved regulatory compliance, meeting ROHS3 requirements compared to the non-compliant status of the original part. Both parts maintain equivalent REACH and ECCN classifications. The 620HR005E is available in bulk packaging, supporting production requirements for new designs and system replacements.

Frequently Asked Questions (FAQ)

Q: Can the 620HR005E be used as a direct replacement for the 620HR005?

A: Yes. The 620HR005E provides identical electrical performance and physical form factor. All critical parameters—resistance, tolerance, power rating, composition, package type, and dimensions—are equivalent.

Q: What is the difference between the 620HR005 and 620HR005E?

A: The primary differences are product status and regulatory compliance. The 620HR005 is obsolete and RoHS non-compliant, while the 620HR005E is an active product meeting ROHS3 requirements. Electrical and mechanical specifications are identical.

Q: Are there packaging differences between these parts?

A: The 620HR005 is supplied with standard packaging, while the 620HR005E is available in bulk packaging. Both maintain the same axial form factor and 0.750" length.

Q: Does the 620HR005E maintain the same safety and performance characteristics?

A: Yes. The 620HR005E retains all functional features of the original part: current sense capability, flame-proof construction, non-inductive design, and safety-rated metal element composition.

Q: What is the inventory status for these parts?

A: The 620HR005 has 905 pieces in stock as new original inventory. The 620HR005E has 1485 pieces available as new original inventory in bulk packaging.
