Parameter Comparison

Engineering Selection Recommendations

Both the SR73W2HTTER200F and SR732HTTER200F are Active products manufactured by KOA Speer Electronics, Inc., with identical electrical, mechanical, and compliance specifications. Selection between these parts is based on availability and supply chain considerations rather than technical differentiation.

SR73W2HTTER200F is suitable for applications where this specific part number is specified in design documentation or procurement requirements.

SR732HTTER200F is suitable as a direct substitute when the SR73W2HTTER200F is unavailable. This part maintains full equivalence across all automotive compliance requirements, including AEC-Q200 qualification, and is compatible with identical PCB layouts and assembly processes.

Both parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 moisture sensitivity rating, indicating no special storage or handling requirements beyond standard component practices.

Frequently Asked Questions (FAQ)

Q: Can SR732HTTER200F be used as a direct replacement for SR73W2HTTER200F in automotive applications?

A: Yes. Both parts are electrically and mechanically identical with matching 200 mOhm resistance, ±1% tolerance, 0.75W power rating, and 2010 package dimensions. Both carry AEC-Q200 automotive qualification and are suitable for current sense applications in automotive systems.

Q: Are there any differences in the physical package between these two parts?

A: No. Both parts use the 2010 (5025 Metric) package with identical dimensions of 0.197" L × 0.098" W (5.00mm × 2.50mm) and maximum seated height of 0.028" (0.70mm). PCB footprints and assembly processes are interchangeable.

Q: Do both parts meet the same automotive compliance standards?

A: Yes. Both SR73W2HTTER200F and SR732HTTER200F are AEC-Q200 qualified, ROHS3 compliant, and REACH unaffected. They meet identical automotive reliability and environmental standards.

Q: What is the difference between the part numbers SR73W2HTTER200F and SR732HTTER200F?

A: The part numbers differ in their base product designations (SR73W2H versus SR732H), but both represent equivalent products within KOA Speer Electronics' SR73 series with identical specifications. The difference reflects internal manufacturer product line organization rather than functional or performance variation.

Q: Are there any temperature or environmental performance differences between these parts?

A: No. Both parts operate across the identical temperature range of -55°C to 150°C with matching ±100ppm/°C temperature coefficient. Both carry MSL 1 moisture sensitivity rating, indicating unlimited shelf life under standard storage conditions.

Q: Can these parts be used interchangeably in existing designs without PCB modification?

A: Yes. The identical 2010 package dimensions, termination count, and electrical specifications allow direct substitution without PCB layout changes or design modifications.
