Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the THS25R10J is determined by strict equivalence across the following critical parameters:

Electrical Specifications: Resistance value (100 mOhms), tolerance (±5%), power rating (25W), composition (wirewound), and temperature coefficient (±50ppm/°C) must be identical.

Thermal Performance: Operating temperature range (-55°C to 200°C) must be maintained.

Mechanical Compatibility: Housing type (aluminum), mounting feature (flanges), lead style (solder lugs), package configuration (axial, box), and physical dimensions (1.142" L x 1.102" W x 0.591" H) must match exactly.

Compliance & Certification: RoHS3 compliance status is required for substitution eligibility.

The HSA25R10J meets all substitution criteria and is classified as a parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both THS25R10J and HSA25R10J are Active products manufactured by TE Connectivity Passive Product with full ROHS3 compliance. Selection between these components is based on inventory availability and supply chain considerations rather than technical performance differences.

The THS25R10J (1138 pieces in stock) and HSA25R10J (1148 pieces in stock) are functionally interchangeable for all circuit applications requiring a 100 mOhms ±5% 25W wirewound chassis mount resistor with flanged mounting and solder lug termination.

Both components satisfy regulatory requirements under ROHS3 and are classified as EAR99 for export control purposes. Selection should prioritize component availability and lead time requirements from your supply chain.

Frequently Asked Questions (FAQ)

Q: Can HSA25R10J be used as a direct replacement for THS25R10J?

A: Yes. The HSA25R10J is a parametric equivalent with identical electrical specifications (100 mOhms ±5%, 25W), mechanical dimensions (1.142" L x 1.102" W x 0.591" H), mounting configuration (flanged solder lugs), and compliance certifications (ROHS3). Direct substitution is supported without circuit modification.

Q: Are there differences in the series designation between these parts?

A: The THS25R10J belongs to the THS and CGS series, while the HSA25R10J belongs to the HS and CGS series. Both share the CGS series classification. The series designation reflects internal TE Connectivity product line organization and does not affect electrical or mechanical compatibility.

Q: What is the significance of the base product numbers THS25 and HSA25?

A: The base product numbers identify the resistor platform within TE Connectivity's product portfolio. THS25 and HSA25 represent different product lines within the same manufacturer, but both deliver identical performance for the 100 mOhms 25W specification.

Q: Are the packaging and lead configurations identical?

A: Yes. Both components use Tray packaging, Axial Box case configuration, and Solder Lugs for termination. Physical dimensions and mounting features are identical, ensuring compatibility with existing PCB layouts and assembly processes.

Q: What is the operating temperature range for both parts?

A: Both THS25R10J and HSA25R10J operate across -55°C to 200°C with a temperature coefficient of ±50ppm/°C, providing equivalent thermal performance for high-temperature applications.

Q: Are there any compliance or regulatory differences?

A: Both components are ROHS3 compliant and classified as EAR99 for export control. REACH status differs slightly (THS25R10J is REACH Unaffected; HSA25R10J is Vendor Undefined), but this does not affect component selection for standard applications.
