Substitute Part Grouping Explanation

Substitute parts for the RC5025F240CS are qualified based on the following substitution criteria:

Electrical Parameters (Must Match or Exceed):

• Resistance value: 24 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: Minimum 0.667W (higher ratings acceptable)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match or wider range acceptable)

Mechanical Parameters (Must Match):

• Package / Case: 2010 (5025 Metric) - exact match required for PCB compatibility
• Physical dimensions: 0.197" L x 0.098" W (5.00mm x 2.50mm) - exact match required
• Number of terminations: 2 - exact match required

Material & Composition (Must Match):

• Composition: Thick Film - exact match required
• Moisture resistance: Required feature

Compliance & Regulatory (Must Match or Exceed):

• RoHS Status: ROHS3 Compliant (minimum requirement)
• Moisture Sensitivity Level: MSL 1 (Unlimited) - exact match required
• REACH Status: REACH Unaffected (maintained)

The AC2010FK-0724RL qualifies as a substitute because it matches all critical electrical parameters, maintains identical package specifications, and exceeds the power rating (0.75W vs. 0.667W), providing enhanced thermal margin while preserving all regulatory compliance requirements.

Both parts are suitable for direct substitution in circuit designs requiring 24 Ohm ±1% resistors in 2010 package format. The AC2010FK-0724RL offers enhanced power handling capability and automotive-grade certification, making it applicable to a broader range of end-use applications while maintaining full electrical and mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the AC2010FK-0724RL directly replace the RC5025F240CS on existing PCBs?

A: Yes. Both components share identical package dimensions (2010/5025 Metric), footprint specifications, and electrical parameters (24 Ohms ±1%, ±100ppm/°C, -55°C ~ 155°C). No PCB layout modifications are required.

Q: What is the significance of the higher power rating on the AC2010FK-0724RL (0.75W vs. 0.667W)?

A: The AC2010FK-0724RL's 0.75W rating exceeds the RC5025F240CS requirement of 0.667W, providing additional thermal headroom. This allows the substitute to operate at higher power dissipation levels without thermal stress, extending component life in demanding applications.

Q: Are there tolerance differences between these parts?

A: No. Both components maintain ±1% tolerance on the 24 Ohm resistance value, ensuring equivalent circuit performance and accuracy.

Q: Does the AEC-Q200 rating on the AC2010FK-0724RL affect general industrial use?

A: No. AEC-Q200 is an automotive qualification standard. The presence of this certification does not restrict use in non-automotive applications; it only confirms the component meets additional automotive reliability requirements.

Q: Are the temperature coefficients identical?

A: Yes. Both components specify ±100ppm/°C temperature coefficient and operate across the identical temperature range of -55°C ~ 155°C.

Q: What is the difference in packaging between these parts?

A: The RC5025F240CS is supplied in standard packaging, while the AC2010FK-0724RL is supplied in Tape & Reel (TR) format. Both are compatible with automated assembly equipment; packaging format selection depends on production volume and assembly process requirements.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the RC5025F240CS and AC2010FK-0724RL are RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What does MSL 1 (Unlimited) mean for storage?

A: MSL 1 (Moisture Sensitivity Level 1) with unlimited shelf life indicates these components do not require special moisture-controlled storage conditions. Standard warehouse storage is acceptable without time-based expiration.

Q: Can these parts be used interchangeably in high-reliability applications?

A: Yes. Both components are Active product status with established manufacturing processes. The AC2010FK-0724RL's AEC-Q200 qualification provides additional assurance for high-reliability requirements.

Q: Are the physical dimensions truly identical?

A: Yes. Both components measure 0.197" L x 0.098" W (5.00mm x 2.50mm) with maximum seated heights of 0.026" (0.66mm and 0.65mm respectively), ensuring identical PCB footprint compatibility.
