Substitute Part Grouping Explanation

The PE1206FRF470R008L from YAGEO qualifies as a substitute for the CSRF1206JT8L00 based on the following critical parameters:

• Identical resistance value: 8 mOhms
• Identical power rating: 1W
• Identical package: 1206 (3216 Metric)
• Identical temperature coefficient: ±100ppm/°C
• Identical operating temperature range: -55°C ~ 170°C
• Identical automotive qualification: AEC-Q200
• Identical moisture sensitivity level: MSL 1 (Unlimited)
• Identical RoHS compliance: ROHS3 Compliant

The substitute part differs in tolerance (±1% versus ±5%) and composition (metal film versus metal foil), representing an upgrade in tolerance specification while maintaining all functional and environmental requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the CSRF1206JT8L00 and PE1206FRF470R008L are active production parts with AEC-Q200 automotive qualification and ROHS3 compliance. The PE1206FRF470R008L provides improved tolerance specification (±1% versus ±5%) while maintaining identical electrical performance, operating temperature range, and environmental ratings. Physical dimensions differ slightly within the 1206 package specification, with the YAGEO part measuring marginally larger. Both parts are suitable for current sense applications in automotive environments with unlimited moisture sensitivity rating.

Frequently Asked Questions (FAQ)

Q: Can PE1206FRF470R008L directly replace CSRF1206JT8L00 in existing designs?

A: Yes. Both parts share identical resistance value, power rating, package designation, temperature coefficient, operating temperature range, and automotive qualification. The substitute part offers improved tolerance specification.

Q: What is the significance of the tolerance difference between ±5% and ±1%?

A: Tolerance defines the acceptable resistance variation from the nominal 8 mOhm value. The ±1% specification of the substitute part provides tighter resistance control, which may benefit precision current sensing applications. The original ±5% specification remains acceptable for applications where this tolerance margin is sufficient.

Q: Are there physical compatibility concerns between these parts?

A: Both parts use the 1206 (3216 Metric) package. The PE1206FRF470R008L dimensions are marginally larger (0.126" L x 0.063" W versus 0.122" L x 0.061" W) and taller (0.035" versus 0.033" maximum seated height). These differences remain within standard 1206 package tolerances and do not affect PCB footprint compatibility.

Q: Do both parts meet automotive requirements?

A: Yes. Both the CSRF1206JT8L00 and PE1206FRF470R008L carry AEC-Q200 qualification, indicating compliance with automotive reliability standards. Both are ROHS3 compliant and have MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the difference between metal foil and metal film composition?

A: Both compositions are suitable for current sense applications. Metal foil and metal film resistors differ in manufacturing process and may have different frequency response characteristics, but both meet the specified electrical parameters for this application.
