Substitute Part Grouping Explanation

Substitution of the NHSC1003R9J is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications for resistance value, tolerance, power rating, temperature coefficient, operating temperature range, physical dimensions, and mounting configuration. These parameters ensure functional and mechanical compatibility within the original application circuit and mechanical assembly.

The HSC1003R9J qualifies as a direct parametric equivalent based on matching all specified electrical characteristics and physical dimensions. The substitution is valid across the following key parameters:

• Resistance: 3.9 Ohms
• Tolerance: ±5%
• Power Rating: 100W
• Wirewound composition
• Temperature Coefficient: ±50ppm/°C
• Operating Temperature: -55°C ~ 200°C
• Aluminum housing with flanged mounting
• Identical physical dimensions and lead configuration

Engineering Selection Recommendations

The HSC1003R9J is the direct substitute for the obsolete NHSC1003R9J. Both parts are manufactured by TE Connectivity Passive Product and share identical electrical and mechanical specifications. The primary distinction is product status: the NHSC1003R9J is obsolete, while the HSC1003R9J maintains active production status.

The HSC1003R9J provides enhanced compliance through ROHS3 certification, compared to the RoHS compliance of the original part. This upgrade in regulatory compliance supports long-term supply chain continuity and regulatory alignment for new designs and system updates.

Both parts are suitable for applications requiring 100W power dissipation at 3.9 Ohms resistance with stable performance across the -55°C to 200°C operating temperature range. The identical physical dimensions and flanged mounting configuration ensure direct mechanical and electrical interchangeability within existing circuit board layouts and mechanical assemblies.
