Parameter Comparison

Engineering Selection Recommendations

Both the HS100F 2R F 200MM M372 and HS100E6 2R F M193 are functionally and mechanically interchangeable. Selection between these parts should be based on:

Inventory Availability: The HS100F 2R F 200MM M372 maintains 902 pieces in stock, while the HS100E6 2R F M193 maintains 739 pieces in stock. Either part may be selected based on procurement lead time and supply chain requirements.

Compliance Certification: Both parts maintain identical compliance status under ROHS3, REACH, and export control classifications (EAR99, HTSUS 8533.29.0000). Either part satisfies regulatory requirements for equivalent applications.

Product Status: Both parts maintain active product status with Ohmite, ensuring continued availability and technical support.

Electrical Performance: Identical electrical specifications (2 Ohms ±1%, 100W, ±100ppm/°C temperature coefficient) ensure equivalent performance in circuit applications.

Mechanical Integration: Identical physical dimensions, flanged mounting features, and solder lug lead style ensure direct mechanical compatibility in existing designs without modification to PCB layouts or mechanical assemblies.

Frequently Asked Questions (FAQ)

Q: Can HS100E6 2R F M193 be used as a direct replacement for HS100F 2R F 200MM M372?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters. Direct substitution is valid without circuit redesign or mechanical modification.

Q: Are there differences in the part numbering that indicate functional variations?

A: The part numbers reflect different packaging or manufacturing lot designations within the ARCOL HS series. The "F" designation in both part numbers indicates flanged mounting. The "E6" in the substitute part number refers to E6 series tolerance grading. Both parts maintain ±1% tolerance specification. No functional variation exists.

Q: Do both parts meet the same regulatory compliance requirements?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and classified under identical export control (EAR99) and tariff codes (HTSUS 8533.29.0000).

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by matching: resistance value (2 Ohms), tolerance (±1%), power rating (100W), temperature coefficient (±100ppm/°C), composition (wirewound), housing type (aluminum), mounting feature (flanges), lead style (solder lugs), physical dimensions (2.567" L x 1.870" W x 0.949" H), and compliance certifications (ROHS3, REACH, EAR99).

Q: Are there any lead time or availability considerations between these parts?

A: The HS100F 2R F 200MM M372 has 902 pieces in current inventory, while the HS100E6 2R F M193 has 739 pieces. Selection may be based on immediate availability requirements and procurement timelines.

Q: Can these parts be used in high-reliability or military applications?

A: Both parts are manufactured by Ohmite and maintain active product status. Application suitability for high-reliability or military use depends on specific program requirements and qualification documentation beyond the parameters provided in this reference.

Q: What is the difference between the packaging designations "M372" and "M193"?

A: Both parts are supplied in box packaging. The alphanumeric suffixes (M372 and M193) represent different packaging lot or manufacturing designations. Both are equivalent for component selection purposes.
