Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RMCP1210FT2R00 are qualified based on the following criteria:

• Identical resistance value: 2 Ohms
• Matching tolerance: ±1%
• Identical package: 1210 (3225 Metric)
• Identical composition: Thick Film
• Matching operating temperature range: -55°C to 155°C
• Equivalent or superior automotive qualification: AEC-Q200
• RoHS3 compliance
• MSL 1 rating

The substitute parts AC1210FR-072RL and RC1210FR-072RL meet all core electrical and mechanical compatibility requirements. Both are manufactured by YAGEO and maintain the same resistance, tolerance, package, and temperature operating range. The primary difference is the power rating: substitute parts are rated at 0.5W (1/2W) compared to the main part's 0.667W (2/3W). This represents a lower power dissipation capability and must be evaluated against circuit requirements.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts maintain full electrical and mechanical compatibility with the RMCP1210FT2R00 for applications within their power rating specifications. Selection between the main part and substitutes should be based on the following factors:

Power Dissipation Requirements: The main part RMCP1210FT2R00 is rated for 0.667W, while both substitutes are rated for 0.5W. Applications requiring power dissipation above 0.5W must use the main part or verify that actual circuit power dissipation remains within the 0.5W limit of the substitutes.

Automotive Applications: AC1210FR-072RL carries explicit AEC-Q200 automotive qualification. RC1210FR-072RL does not specify AEC-Q200 rating and should be evaluated for automotive use cases where this certification is mandatory.

Temperature Stability: Both substitutes feature superior temperature coefficient (±200ppm/°C) compared to the main part (±400ppm/°C), providing better stability across the operating temperature range.

Compliance and Certifications: All three parts are ROHS3 compliant, MSL 1 rated, and available in Tape & Reel packaging. Substitutes maintain equivalent regulatory and environmental compliance.

Frequently Asked Questions (FAQ)

Q: Can AC1210FR-072RL and RC1210FR-072RL be used interchangeably with RMCP1210FT2R00?

A: Both substitutes are electrically and mechanically compatible for applications where power dissipation does not exceed 0.5W. The main part's higher 0.667W rating provides additional thermal margin. For automotive applications, AC1210FR-072RL is preferred due to explicit AEC-Q200 qualification.

Q: What is the impact of the lower power rating on substitute parts?

A: The 0.5W rating of substitute parts limits maximum continuous power dissipation. Circuit design must ensure actual power dissipation remains below this threshold. If circuit analysis indicates power dissipation between 0.5W and 0.667W, the main part RMCP1210FT2R00 is required.

Q: Are the physical dimensions compatible?

A: All three parts use the 1210 (3225 Metric) package. Slight dimensional variations exist: main part is 0.126" L × 0.098" W (3.20mm × 2.50mm) with 0.028" height; substitutes are 0.122" L × 0.102" W (3.10mm × 2.60mm) with 0.024" height. These variations are within standard 1210 package tolerances and do not affect PCB footprint compatibility.

Q: Which substitute is recommended for automotive applications?

A: AC1210FR-072RL is the preferred substitute for automotive applications due to explicit AEC-Q200 qualification and moisture-resistant features. RC1210FR-072RL lacks specified automotive certification.

Q: What is the difference in temperature coefficient between the main part and substitutes?

A: The main part has ±400ppm/°C while both substitutes have ±200ppm/°C. The substitutes provide superior temperature stability, resulting in better resistance value stability across the -55°C to 155°C operating range.

Q: Are all parts RoHS compliant?

A: Yes, all three parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, meeting current environmental and regulatory requirements.
