Key Parameters

Substitute Part Grouping Explanation

The RC0201JR-071RL qualifies as an equivalent substitute based on the following critical parameters:

• Resistance value and tolerance match exactly: 1 Ohms ±5%
• Power rating is identical: 0.05W (1/20W)
• Package and physical dimensions are identical: 0201 (0603 Metric), 0.024" L x 0.012" W, 0.010" max height
• Composition is identical: Thick Film
• Temperature coefficient matches: -100 / +350 ppm/°C
• Number of terminations: 2 (both parts)
• Compliance certifications align: ROHS3 Compliant, REACH Unaffected
• Moisture Sensitivity Level: 1 (Unlimited)

The primary difference is the operating temperature range of the substitute part, which extends to -55°C ~ 125°C compared to the main part's -55°C ~ 155°C. This represents a narrower upper temperature limit and must be evaluated against application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both parts maintain active production status and full compliance with ROHS3 and REACH regulations. The RC0201JR-071RL substitute provides equivalent electrical performance and identical mechanical fit within standard PCB assembly processes. Selection between these parts should be based on application operating temperature requirements. If the circuit operates exclusively within the -55°C ~ 125°C range, the RC0201JR-071RL is functionally equivalent. Applications requiring operation above 125°C must use the AC0201JR-071RL to maintain specified performance within the full -55°C ~ 155°C operating window. Both parts carry identical moisture sensitivity ratings and are suitable for automated assembly with standard reflow profiles.

Frequently Asked Questions (FAQ)

Q: Can RC0201JR-071RL replace AC0201JR-071RL in all applications?

A: Substitution is valid only when the application operating temperature does not exceed 125°C. The RC0201JR-071RL has a maximum operating temperature of 125°C, while the AC0201JR-071RL extends to 155°C. Verify your circuit's thermal environment before substitution.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts use the 0201 (0603 Metric) package with identical dimensions of 0.024" L x 0.012" W and maximum seated height of 0.010" (0.26mm). They are mechanically interchangeable on PCB layouts.

Q: Do both parts have the same electrical specifications?

A: Yes. Resistance (1 Ohms), tolerance (±5%), power rating (0.05W), composition (Thick Film), and temperature coefficient (-100 / +350 ppm/°C) are identical across both parts.

Q: What is the difference between AC and RC series designations?

A: The AC series includes AEC-Q200 automotive qualification. The RC series does not carry this automotive rating. Select based on whether your application requires automotive-grade certification.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both AC0201JR-071RL and RC0201JR-071RL are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.

Q: What is the Moisture Sensitivity Level (MSL) for these parts?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling. Standard PCB assembly processes are suitable without special precautions.
