Substitute Part Grouping Explanation

Substitution eligibility for the PWR263S-35-4000FE is determined by strict equivalence across the following critical parameters: resistance value (400 Ohms), tolerance (±1%), power rating (35W), package configuration (TO-263-3 D2PAK), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and automotive qualification (AEC-Q200). The identified substitute PWR263S-35-4000F shares identical specifications across all electrical and mechanical parameters, differing only in packaging designation suffix. Both parts are manufactured by Bourns Inc. within the same PWR263S-35 series and maintain equivalent performance characteristics for current sensing applications.

Parameter Comparison

Engineering Selection Recommendations

Both PWR263S-35-4000FE and PWR263S-35-4000F are active production components from Bourns Inc. with full AEC-Q200 automotive qualification. Selection between these parts is based on availability and packaging designation requirements. The PWR263S-35-4000FE maintains 1109 pieces in current inventory, while PWR263S-35-4000F has 1187 pieces available. Both components satisfy ROHS3 compliance and REACH unaffected status requirements. For applications requiring automotive-grade current sensing resistors with 35W power dissipation in D2PAK configuration, either part provides equivalent electrical performance and thermal characteristics within the specified operating range.

Frequently Asked Questions (FAQ)

Q: Can PWR263S-35-4000F be used as a direct replacement for PWR263S-35-4000FE?

A: Yes. Both parts are electrically and mechanically identical, sharing the same resistance value, tolerance, power rating, package configuration, and automotive qualification. The suffix designation difference does not affect functional compatibility.

Q: What determines substitution eligibility for this resistor?

A: Substitution is valid when the following parameters match: 400 Ohm resistance, ±1% tolerance, 35W power rating, TO-263-3 D2PAK package, ±100ppm/°C temperature coefficient, -55°C to 155°C operating range, and AEC-Q200 automotive rating.

Q: Are both parts suitable for current sensing applications?

A: Yes. Both PWR263S-35-4000FE and PWR263S-35-4000F are specified for current sensing applications with pulse withstanding capability and automotive AEC-Q200 qualification.

Q: What is the significance of the packaging designation suffix?

A: The suffix (FE versus F) indicates packaging tube designation. This does not affect electrical performance or mechanical fit. Both parts use identical D2PAK TO-263-3 package configuration.

Q: Are there any compliance differences between these parts?

A: No. Both parts maintain identical RoHS3 compliance, REACH unaffected status, MSL 1 rating, and automotive qualification standards.
