Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RG2012P-221-P-T1 is determined by the following critical parameters:

Primary Substitution Criteria:

• Resistance value: 220 Ohms (exact match required)
• Package type: 0805 (2012 Metric) (exact match required)
• Power rating: 0.125W minimum (equal or greater acceptable)
• Composition: Thin film (maintains performance characteristics)
• Automotive qualification: AEC-Q200 (required for automotive applications)
• Operating temperature range: -55°C to 155°C minimum (equal or greater range acceptable)

Secondary Compatibility Factors:

• Tolerance: ±0.02% or tighter (equal or better acceptable)
• Temperature coefficient: ±25ppm/°C or lower (equal or better acceptable)
• RoHS and REACH compliance status
• Moisture sensitivity level

Substitute parts must maintain identical electrical specifications for resistance and power rating while meeting or exceeding precision and thermal stability requirements. Packaging format must remain consistent for PCB assembly compatibility.

Engineering Selection Recommendations

RG2012V-221-P-T1 (Upgrade Substitute)

The RG2012V-221-P-T1 is the primary equivalent for the obsolete RG2012P-221-P-T1. This part maintains identical electrical specifications including 220 Ohms resistance, ±0.02% tolerance, and 0.125W power rating. The upgrade variant features an improved temperature coefficient of ±5ppm/°C compared to the original ±25ppm/°C, providing superior thermal stability. Both parts share identical package dimensions (0805), AEC-Q200 automotive qualification, anti-sulfur coating, and ROHS3 compliance. The RG2012V-221-P-T1 is currently in active production status with higher inventory availability (1038 Pcs), ensuring supply continuity. This substitute is suitable for direct replacement in all applications where the original part was specified.

RG2012P-221-B-T5 (Similar Substitute)

The RG2012P-221-B-T5 provides functional equivalence with a tolerance specification of ±0.1% compared to the original ±0.02%. This part is appropriate for applications where the tighter tolerance of the original component is not a critical design requirement. The RG2012P-221-B-T5 maintains identical resistance value, power rating, package format, operating temperature range, and automotive AEC-Q200 qualification. Temperature coefficient remains at ±25ppm/°C, matching the original specification. This substitute offers significantly higher inventory availability (14885 Pcs) and is recommended for applications with relaxed tolerance requirements or where cost optimization is a consideration.

Frequently Asked Questions (FAQ)

Q: Can the RG2012V-221-P-T1 be used as a direct replacement for the RG2012P-221-P-T1?

A: Yes. The RG2012V-221-P-T1 is a direct substitute with identical electrical specifications (220 Ohms, ±0.02% tolerance, 0.125W power rating) and package format (0805). The improved temperature coefficient (±5ppm/°C versus ±25ppm/°C) provides enhanced performance. Both parts are AEC-Q200 qualified, anti-sulfur coated, and ROHS3 compliant.

Q: What is the key difference between the RG2012V-221-P-T1 and RG2012P-221-B-T5?

A: The primary difference is tolerance specification. The RG2012V-221-P-T1 maintains the original ±0.02% tolerance, while the RG2012P-221-B-T5 has ±0.1% tolerance. Both share identical resistance, power rating, package, and operating temperature range. Selection depends on application tolerance requirements.

Q: Are all three parts compatible with automotive applications?

A: Yes. All three parts (RG2012P-221-P-T1, RG2012V-221-P-T1, and RG2012P-221-B-T5) carry AEC-Q200 automotive qualification and anti-sulfur coating, making them suitable for automotive circuit applications.

Q: Does the packaging format differ between these parts?

A: The main part (RG2012P-221-P-T1) uses standard packaging, while both substitutes (RG2012V-221-P-T1 and RG2012P-221-B-T5) are supplied in Tape & Reel (TR) format. All three parts use identical 0805 (2012 Metric) package dimensions, ensuring PCB assembly compatibility.

Q: Which substitute should be selected for high-precision applications?

A: The RG2012V-221-P-T1 is recommended for high-precision applications. It maintains the original ±0.02% tolerance specification and provides superior temperature stability with ±5ppm/°C temperature coefficient, compared to ±25ppm/°C in the original part.

Q: Is the RG2012P-221-B-T5 suitable for all applications where the original part was used?

A: The RG2012P-221-B-T5 is suitable for applications where tolerance of ±0.1% is acceptable. Applications requiring the original ±0.02% tolerance specification should use the RG2012V-221-P-T1 instead.

Q: What is the moisture sensitivity level for these parts?

A: All three parts have Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without moisture control requirements.

Q: Are these parts RoHS compliant?

A: Yes. All three parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
