Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

• Resistance Value: Must be 221 Ohms (exact match required)
• Package Format: Must be 1206 (3216 Metric) for PCB footprint compatibility
• Power Rating: Must be 0.25W minimum
• Composition: Thin film technology maintained across all substitutes
• Operating Temperature Range: Must support -55°C to 155°C minimum
• Termination Count: Must be 2-terminal configuration
• RoHS Compliance: ROHS3 Compliant status required

Substitute parts are grouped by tolerance specification and automotive qualification status. Tighter tolerance variants (±0.1%, ±0.5%) provide improved accuracy over the base ±1% specification. The Panasonic ERA-8AEB2210V adds automotive AEC-Q200 qualification for applications requiring enhanced reliability standards.

Parameter Comparison

Engineering Selection Recommendations

RT1206BRD07221RL (YAGEO, ±0.1% Tolerance): Select this substitute when circuit design requires improved tolerance accuracy and reduced temperature coefficient (±25ppm/°C vs. ±50ppm/°C). Maintains YAGEO series continuity with enhanced performance specifications. Active product status with high inventory availability.

RT1206DRE07221RL (YAGEO, ±0.5% Tolerance): Select this substitute as an intermediate tolerance option between standard ±1% and precision ±0.1% specifications. Maintains original temperature coefficient of ±50ppm/°C. Suitable for applications requiring moderate tolerance improvement without precision-grade cost implications.

ERA-8AEB2210V (Panasonic, ±0.1% Tolerance, AEC-Q200): Select this substitute for automotive applications or systems requiring AEC-Q200 qualification. Provides ±0.1% tolerance and ±25ppm/°C temperature coefficient. Physical dimensions vary slightly (0.126" L x 0.063" W vs. 0.122" L x 0.063" W; height 0.028" vs. 0.026"), requiring PCB layout verification. ROHS3 Compliant and MSL 1 rated.

Frequently Asked Questions (FAQ)

Q: Can RT1206BRD07221RL be used as a direct replacement for RT1206FRE07221RL?

A: Yes. Both components share identical resistance value (221 Ohms), power rating (0.25W), package format (1206), operating temperature range (-55°C to 155°C), and RoHS compliance. The RT1206BRD07221RL provides tighter tolerance (±0.1% vs. ±1%) and improved temperature coefficient (±25ppm/°C vs. ±50ppm/°C), making it functionally compatible with enhanced performance characteristics.

Q: What is the difference between RT1206DRE07221RL and RT1206BRD07221RL?

A: Both are YAGEO 1206 thin film resistors with 221 Ohms resistance. RT1206BRD07221RL offers ±0.1% tolerance and ±25ppm/°C temperature coefficient. RT1206DRE07221RL offers ±0.5% tolerance and ±50ppm/°C temperature coefficient. Selection depends on circuit accuracy requirements and cost considerations.

Q: Is ERA-8AEB2210V suitable for non-automotive applications?

A: Yes. ERA-8AEB2210V meets all electrical and mechanical requirements for general-purpose applications. AEC-Q200 qualification indicates enhanced reliability testing and is not restrictive for non-automotive use. Physical dimensions require verification against PCB layout specifications.

Q: Are there package compatibility concerns with ERA-8AEB2210V?

A: ERA-8AEB2210V uses 1206 (3216 Metric) package format compatible with standard 1206 footprints. Physical dimensions are 0.126" L x 0.063" W (vs. 0.122" L x 0.063" W for YAGEO variants) and height 0.028" (vs. 0.026"). Verify PCB layout tolerances and clearance specifications before substitution.

Q: Do all substitute parts maintain MSL 1 rating?

A: Yes. All listed substitutes maintain Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity precautions are required during storage, handling, or assembly.
