Substitute Part Grouping Explanation

Substitution eligibility for the AC1210JR-0727RL is determined by the following critical parameters:

• Resistance Value: Must be 27 Ohms
• Package / Case: Must be 1210 (3225 Metric) for mechanical and thermal compatibility
• Power Rating: Must be 0.5W minimum
• Composition: Thick film construction
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C minimum
• Terminations: 2-terminal configuration
• RoHS Compliance: ROHS3 Compliant

The RC1210FR-0727RL qualifies as a direct substitute by meeting all critical parameters while offering improved tolerance specification (±1% versus ±5%).

Parameter Comparison

Engineering Selection Recommendations

The RC1210FR-0727RL serves as a direct substitute for the AC1210JR-0727RL with the following considerations:

Both parts are manufactured by YAGEO and maintain identical mechanical dimensions, thermal characteristics, and compliance certifications. The RC1210FR-0727RL provides improved tolerance specification at ±1% compared to the AC1210JR-0727RL at ±5%, making it suitable for applications requiring tighter resistance accuracy. Both parts are ROHS3 compliant and carry MSL 1 rating, indicating no moisture sensitivity limitations. The AC1210JR-0727RL includes AEC-Q200 automotive qualification, while the RC1210FR-0727RL does not specify this rating in the provided data. Selection between these parts depends on whether automotive AEC-Q200 qualification is a mandatory requirement for the application.

Frequently Asked Questions (FAQ)

Q: Can RC1210FR-0727RL replace AC1210JR-0727RL in automotive applications?

A: Both parts share identical mechanical and thermal specifications. The RC1210FR-0727RL does not carry AEC-Q200 qualification in the provided specifications. If AEC-Q200 certification is required, the AC1210JR-0727RL must be used. If AEC-Q200 is not mandatory, the RC1210FR-0727RL is mechanically and electrically compatible.

Q: What is the tolerance difference between these parts?

A: The AC1210JR-0727RL has ±5% tolerance, while the RC1210FR-0727RL has ±1% tolerance. The tighter tolerance of the RC1210FR-0727RL may benefit circuits requiring higher resistance accuracy.

Q: Are the package dimensions identical?

A: Yes. Both parts use the 1210 (3225 Metric) package with dimensions of 0.122" L x 0.102" W (3.10mm x 2.60mm) and maximum seated height of 0.024" (0.60mm). They are mechanically interchangeable on PCBs designed for 1210 resistors.

Q: Do both parts have the same moisture sensitivity rating?

A: Yes. Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity limitations during storage or handling.

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

A: Both parts operate across -55°C to 155°C with a temperature coefficient of ±100ppm/°C.
