RG2012P-221-D-T5 Equivalent & Substitute Parts

Part Overview

The RG2012P-221-D-T5 is a 220 Ohms ±0.5% thin film chip resistor manufactured by Susumu in 0805 (2012 Metric) package format. This surface-mount device is rated for 0.125W (1/8W) power dissipation and is qualified to automotive AEC-Q200 standards with anti-sulfur coating. The part is active in production status with 5100 units currently in stock. Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and regulatory compliance can be maintained across alternative manufacturers or enhanced tolerance specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RG2012P-221-D-T5 is determined by the following criteria:

Mandatory Compatibility Parameters:

• Resistance value: 220 Ohms
• Package format: 0805 (2012 Metric)
• Power rating: 0.125W minimum
• Operating temperature range: -55°C ~ 155°C minimum
• Composition: Thin film
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

Allowable Variations:

• Tolerance: ±0.5% or tighter (±0.1% acceptable)
• Temperature coefficient: ±25ppm/°C or tighter (±10ppm/°C acceptable)
• Automotive AEC-Q200 rating: required for direct substitution
• Physical height: up to 0.024" (0.60mm) acceptable for 0805 package

Substitute parts meeting these criteria are functionally interchangeable in applications where the RG2012P-221-D-T5 is specified, provided the tighter tolerance or improved temperature coefficient does not create cost or procurement constraints.

Parameter Comparison

Engineering Selection Recommendations

RG2012N-221-D-T5 (Susumu) This substitute maintains identical tolerance (±0.5%) and package specifications as the main part. The improved temperature coefficient (±10ppm/°C versus ±25ppm/°C) provides enhanced stability across the operating temperature range. Both parts carry AEC-Q200 automotive qualification and ROHS3 compliance. Selection is appropriate for applications requiring improved thermal stability without tolerance upgrades.

RG2012P-221-B-T5 (Susumu) This substitute offers tighter tolerance (±0.1% versus ±0.5%) while maintaining identical package, power rating, and temperature coefficient specifications. AEC-Q200 automotive qualification and ROHS3 compliance are maintained. Selection is appropriate for precision applications requiring improved resistance accuracy.

ERA-6AEB221V (Panasonic Electronic Components) This substitute provides ±0.1% tolerance with identical power rating and operating temperature range. The part carries AEC-Q200 automotive qualification and ROHS3 compliance. Physical height is 0.024" (0.60mm) compared to 0.020" (0.50mm) for the main part, remaining within 0805 package specifications. Selection is appropriate for precision applications with higher inventory availability.

RT0805BRD07220RL (YAGEO) This substitute provides ±0.1% tolerance with identical power rating and operating temperature range. ROHS3 compliance is maintained. Automotive AEC-Q200 rating is not specified for this part. Physical height is 0.024" (0.60mm). Selection is appropriate for non-automotive applications or where AEC-Q200 qualification is not required.

Frequently Asked Questions (FAQ)

Q: Can RG2012N-221-D-T5 be used as a direct replacement for RG2012P-221-D-T5?

A: Yes. Both parts share identical resistance (220 Ohms), tolerance (±0.5%), power rating (0.125W), package (0805), and operating temperature range (-55°C ~ 155°C). The RG2012N-221-D-T5 features improved temperature coefficient (±10ppm/°C) and maintains AEC-Q200 automotive qualification and ROHS3 compliance.

Q: What is the difference between ±0.5% and ±0.1% tolerance specifications?

A: Tolerance defines the maximum allowable deviation from the nominal resistance value. A ±0.5% tolerance on a 220 Ohm resistor allows deviation of ±1.1 Ohms (219-221 Ohms range). A ±0.1% tolerance allows deviation of ±0.22 Ohms (219.78-220.22 Ohms range). Tighter tolerance (±0.1%) is required for precision analog circuits and measurement applications.

Q: Are all substitute parts AEC-Q200 qualified?

A: RG2012N-221-D-T5, RG2012P-221-B-T5, and ERA-6AEB221V carry AEC-Q200 automotive qualification. RT0805BRD07220RL does not specify AEC-Q200 rating. For automotive applications, select only parts with documented AEC-Q200 qualification.

Q: Does the physical height difference between 0.020" and 0.024" affect PCB assembly?

A: Both heights fall within 0805 (2012 Metric) package specifications. The 0.004" (0.10mm) height difference does not affect PCB layout, reflow soldering, or component placement. Parts are mechanically interchangeable on standard 0805 footprints.

Q: Can RT0805BRD07220RL be used in automotive applications?

A: RT0805BRD07220RL does not carry AEC-Q200 automotive qualification. Use this part only in non-automotive applications or where automotive qualification is not required. For automotive designs, select RG2012N-221-D-T5, RG2012P-221-B-T5, or ERA-6AEB221V.

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

A: MSL 1 (Unlimited) indicates the component has no moisture sensitivity limitations. The part can be stored indefinitely without desiccant packaging and does not require special handling or baking procedures prior to soldering.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (RG2012N-221-D-T5, RG2012P-221-B-T5, ERA-6AEB221V, and RT0805BRD07220RL) are ROHS3 compliant and suitable for applications requiring RoHS compliance.
