• Power rating: Equal to or greater than 0.125W
• Temperature coefficient: Equal to or lower absolute value
• Operating temperature range: Must encompass -55°C ~ 155°C minimum

Mechanical Compatibility Requirements:

• Package: 0805 (2012 Metric) form factor
• Physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm)
• Number of terminations: 2

Compliance Requirements:

• Composition: Thin film construction
• Features: Anti-sulfur coating and AEC-Q200 automotive rating

• MSL rating: 1 (Unlimited)

All substitute parts listed meet these criteria and are available from active product lines, ensuring long-term supply continuity and design reliability.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Susumu RG Series):

The Susumu RG2012N and RG2012V series parts provide direct electrical and mechanical compatibility with the obsolete RG2012N-2101-C-T5. All active alternatives maintain the 0805 package form factor, 2.1 kOhms resistance value, 0.125W power rating, and AEC-Q200 automotive qualification.

Tolerance Upgrade Path:

Substitution with tighter tolerance specifications (±0.1%, ±0.05%, or ±0.02%) is permissible where circuit design permits. The RG2012N-2101-B-T5 (±0.1% tolerance) and RG2012N-2101-W-T5 (±0.05% tolerance) represent direct upgrades maintaining the ±10ppm/°C temperature coefficient of the original part.

Enhanced Temperature Stability:

The RG2012V series variants offer improved temperature coefficient performance (±5ppm/°C versus ±10ppm/°C), providing superior stability across the -55°C ~ 155°C operating range. RG2012V-2101-B-T5, RG2012V-2101-W-T1, RG2012V-2101-W-T5, and RG2012V-2101-P-T1 are suitable for applications requiring enhanced thermal performance.

Cross-Manufacturer Alternative:

The Vishay Dale TNPW08052K10BYEA provides functional equivalence with increased power dissipation capability (0.26W versus 0.125W) and extended upper operating temperature limit (175°C versus 155°C). This part maintains ±0.1% tolerance and AEC-Q200 compliance. Physical dimensions remain compatible at 0805 package specification.

Compliance Verification:

All substitute parts maintain ROHS3 compliance, MSL rating of 1 (Unlimited), and AEC-Q200 automotive qualification. No additional qualification or testing is required for direct substitution in existing designs.

Frequently Asked Questions (FAQ)

Q: Can RG2012N-2101-C-T5 be replaced with a tighter tolerance variant?

A: Yes. The RG2012N-2101-B-T5 (±0.1%), RG2012N-2101-W-T5 (±0.05%), and RG2012V-2101-P-T1 (±0.02%) are direct substitutes with improved tolerance specifications. Tighter tolerance does not compromise circuit compatibility and may enhance performance in precision applications.

Q: What is the difference between RG2012N and RG2012V series?

A: The primary difference is temperature coefficient. RG2012N variants specify ±10ppm/°C, while RG2012V variants specify ±5ppm/°C. Both series maintain identical resistance values, power ratings, and package dimensions. RG2012V selection is appropriate for applications requiring superior temperature stability.

Q: Is the Vishay Dale TNPW08052K10BYEA a suitable replacement?

A: Yes. The TNPW08052K10BYEA maintains 2.1 kOhms resistance, ±0.1% tolerance, 0805 package form factor, and AEC-Q200 compliance. The increased power rating (0.26W) and extended temperature range (-55°C ~ 175°C) provide additional design margin. Physical compatibility is confirmed at 0805 package specification.

Q: Are all substitute parts available in Tape & Reel packaging?

A: Yes. All listed substitute parts are supplied in Tape & Reel (TR) packaging format, maintaining consistency with standard surface mount assembly processes.

Q: Do substitute parts require re-qualification for automotive applications?

A: No. All substitute parts carry AEC-Q200 automotive qualification and ROHS3 compliance matching the original part specification. Direct substitution is permissible without additional qualification.

Q: What is the impact of selecting a higher power-rated substitute?

A: Selection of the TNPW08052K10BYEA (0.26W) in place of the 0.125W original part provides additional thermal margin and does not negatively impact circuit performance. The higher power rating accommodates greater current flow without thermal stress, benefiting long-term reliability in high-current applications.

Q: Are there any package dimension differences between substitutes?

A: All substitute parts conform to 0805 (2012 Metric) package specification with dimensions of 0.079" L x 0.049" W (2.00mm x 1.25mm). Height variations are minimal (0.020" to 0.022" seated maximum) and do not affect PCB assembly compatibility.
