Key Parameters

Substitute Part Grouping Explanation

Substitution of the RG2012V-302-B-T1 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 3 kOhms
• Package type: 0805 (2012 Metric)
• Power rating: 0.125W (1/8W)
• Composition: Thin Film
• Temperature coefficient: ±5ppm/°C
• Automotive qualification: AEC-Q200
• Anti-sulfur feature

Allowable Variation Parameters:

• Tolerance: Can be equal (±0.1%) or tighter (±0.05%, ±0.02%)
• Packaging format: Bulk or Tape & Reel (TR)
• Manufacturer: Susumu or Vishay Dale
• Operating temperature range: Can be equal or extended

Substitute parts are grouped into two categories:

Direct Equivalents: Parts with identical tolerance (±0.1%) and all other matching parameters. These provide one-to-one replacement capability.

Upgrade Equivalents: Parts with tighter tolerance specifications (±0.05% or ±0.02%) while maintaining all other critical parameters. These provide enhanced precision performance.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Identical Specifications):

RG2012V-302-B-T5 is the primary direct equivalent, offering identical electrical specifications and tolerance to the obsolete RG2012V-302-B-T1. Both are Susumu RG series components with ±0.1% tolerance. The difference is packaging format: RG2012V-302-B-T5 is supplied in Tape & Reel format, which is standard for production environments. This part is active and maintains full AEC-Q200 automotive qualification.

TNPU08053K00BZEN00 (Vishay Dale TNPU e3 series) provides an alternative direct equivalent from a different manufacturer. This part matches the ±0.1% tolerance and all critical electrical parameters. Operating temperature range is -55°C ~ 125°C, which is narrower than the Susumu equivalent but remains suitable for most automotive applications. This part includes moisture-resistant construction and is active in production.

For Enhanced Precision Requirements:

RG2012V-302-W-T1 and RG2012V-302-W-T5 offer ±0.05% tolerance, providing tighter resistance accuracy than the original specification. Both are Susumu RG series, active products supplied in Tape & Reel format. Selection between T1 and T5 variants depends on packaging requirements.

RG2012V-302-P-T1 provides the highest precision option with ±0.02% tolerance. This Susumu RG series component is suitable for applications requiring superior resistance stability and is supplied in Tape & Reel format.

All substitute parts maintain AEC-Q200 automotive qualification, ROHS3 compliance, and anti-sulfur construction. All are rated for MSL 1 (Unlimited moisture sensitivity level).

Frequently Asked Questions (FAQ)

Q: Can RG2012V-302-B-T5 be used as a direct replacement for RG2012V-302-B-T1?

A: Yes. RG2012V-302-B-T5 is a direct electrical equivalent with identical resistance (3 kOhms), tolerance (±0.1%), power rating (0.125W), package (0805), and all other critical parameters. The only difference is packaging format: RG2012V-302-B-T5 is supplied in Tape & Reel format rather than bulk. Both parts are Susumu RG series with AEC-Q200 qualification.

Q: What is the difference between the Susumu and Vishay Dale options?

A: Both TNPU08053K00BZEN00 (Vishay Dale) and RG2012V-302-B-T5 (Susumu) provide ±0.1% tolerance equivalents. The Vishay part has a narrower operating temperature range (-55°C ~ 125°C versus -55°C ~ 155°C) and includes moisture-resistant construction. Both are AEC-Q200 qualified and active in production. Selection depends on temperature requirements and supplier availability.

Q: Can I use a tighter tolerance part (±0.05% or ±0.02%) as a substitute?

A: Yes. Parts with tighter tolerance specifications (RG2012V-302-W-T1, RG2012V-302-W-T5, RG2012V-302-P-T1) are functionally compatible substitutes. Tighter tolerance means the actual resistance value will be closer to the nominal 3 kOhms specification. These upgrades do not introduce incompatibility and are suitable for applications where enhanced precision is beneficial or required.

Q: What is the significance of the T1 versus T5 designation?

A: The T1 and T5 designations indicate packaging format. T1 represents Tape & Reel packaging in standard quantities, while T5 also represents Tape & Reel but may differ in reel size or quantity per reel. Both formats are suitable for automated assembly. Consult packaging specifications for exact reel configurations and minimum order quantities.

Q: Are all substitute parts AEC-Q200 qualified?

A: Yes. All substitute parts listed maintain AEC-Q200 automotive qualification, anti-sulfur construction, and ROHS3 compliance. All are rated MSL 1 (Unlimited moisture sensitivity level), making them suitable for automotive and high-reliability applications.

Q: What is the physical size compatibility between parts?

A: All parts use the 0805 (2012 Metric) package with identical footprint dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm). Height specifications are equivalent (0.020" to 0.022" seated maximum), ensuring PCB layout and assembly compatibility.

Q: Which substitute should I select for new production?

A: RG2012V-302-B-T5 is the recommended primary choice for new production, offering direct electrical equivalence to the obsolete part with active product status and standard Tape & Reel packaging. If tighter tolerance is required, RG2012V-302-W-T1 or RG2012V-302-P-T1 provide enhanced precision options from the same manufacturer.
