Key Parameters

Substitute Part Grouping Explanation

Substitution of the RG2012V-221-B-T1 is determined by the following critical parameters:

Electrical Parameters:

• Resistance value: 220 Ohms (fixed across all substitutes)
• Power rating: 0.125W (1/8W) (fixed across all substitutes)
• Temperature coefficient: ±5ppm/°C (fixed across all substitutes)
• Tolerance: ±0.1% or tighter (acceptable for direct substitution)

Mechanical Parameters:

• Package: 0805 (2012 Metric) (required for PCB compatibility)
• Physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm) (fixed across all substitutes)

Compliance & Environmental:

• AEC-Q200 automotive qualification (required)
• Thin film composition (required)
• Anti-sulfur construction (required)
• RoHS3 compliance (required)
• MSL 1 rating (required)

Substitutes are grouped into two categories: direct equivalents (identical tolerance and packaging format) and upgrades (improved tolerance specifications while maintaining all other critical parameters).

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (Identical Tolerance ±0.1%):

RG2012V-221-B-T5 and TNPU0805220RBZEN00 are direct functional equivalents to the RG2012V-221-B-T1. Both maintain the ±0.1% tolerance specification and meet all automotive AEC-Q200 requirements. RG2012V-221-B-T5 is a Susumu part with active product status and identical operating temperature range (-55°C ~ 155°C). TNPU0805220RBZEN00 is a Vishay Dale alternative with active product status; however, its maximum operating temperature is limited to 125°C compared to the original 155°C specification.

Upgraded Tolerance Options:

RG2012V-221-W-T1, RG2012V-221-W-T5, and RG2012V-221-P-T1 offer improved tolerance specifications (±0.05% and ±0.02% respectively) while maintaining all other critical electrical and mechanical parameters. These upgrades are suitable for applications requiring tighter resistance tolerances. All three maintain the full -55°C ~ 155°C operating temperature range and active product status.

Packaging Consideration:

The original RG2012V-221-B-T1 is supplied in bulk packaging. All substitute parts are supplied in Tape & Reel (TR) format, which is standard for automated assembly processes. This packaging difference does not affect electrical or mechanical compatibility.

Temperature Range Limitation:

The Vishay Dale TNPU0805220RBZEN00 operates to a maximum of 125°C, which is 30°C below the original specification. This part is suitable only for applications where the upper operating temperature does not exceed 125°C.

Frequently Asked Questions (FAQ)

Q: Can RG2012V-221-B-T5 be used as a direct replacement for RG2012V-221-B-T1?

A: Yes. RG2012V-221-B-T5 is a direct equivalent with identical electrical specifications (220 Ohms ±0.1%, 0.125W), package (0805), composition (thin film), and operating temperature range (-55°C ~ 155°C). The only difference is packaging format (Tape & Reel versus bulk) and active product status. Both are Susumu RG series components with AEC-Q200 qualification.

Q: What is the difference between the tolerance grades offered?

A: The RG2012V-221 series is available in three tolerance grades: ±0.1% (standard), ±0.05% (intermediate), and ±0.02% (precision). All grades maintain identical power rating, package, temperature coefficient, and operating temperature range. Selection depends on circuit accuracy requirements. Tighter tolerance grades are suitable for precision analog circuits and measurement applications.

Q: Is TNPU0805220RBZEN00 suitable for all applications requiring RG2012V-221-B-T1?

A: TNPU0805220RBZEN00 is suitable for applications where the maximum operating temperature does not exceed 125°C. The original RG2012V-221-B-T1 and all Susumu RG2012V-221 variants operate to 155°C. For applications requiring the full -55°C ~ 155°C temperature range, use Susumu equivalents or upgrades.

Q: What does the packaging format difference (bulk versus Tape & Reel) mean for component selection?

A: Bulk packaging is used for manual assembly or small-volume applications. Tape & Reel (TR) packaging is standard for automated pick-and-place assembly. Electrically and mechanically, the components are identical. Selection depends on assembly process requirements, not circuit performance.

Q: Can I use a higher tolerance grade (e.g., ±0.05%) in place of the ±0.1% specification?

A: Yes. A tighter tolerance grade is a functional upgrade and can be used in any application requiring the original ±0.1% tolerance. The ±0.05% and ±0.02% grades provide superior accuracy and are backward-compatible with ±0.1% specifications.

Q: Are all substitute parts AEC-Q200 qualified?

A: Yes. All listed substitute parts meet AEC-Q200 automotive qualification standards, anti-sulfur construction requirements, and RoHS3 compliance. All are suitable for automotive applications.

Q: What is the significance of the "T1" and "T5" designations in the part numbers?

A: The "T" designation indicates Tape & Reel packaging format. The numeric suffix (1 or 5) represents different tape specifications or reel configurations. Electrically and mechanically, T1 and T5 variants are identical; the difference is in packaging configuration for automated assembly equipment compatibility.
