Engineering Selection Recommendations

Direct Equivalent (Same Specifications):

RG2012P-6341-B-T5 (Susumu) is the direct equivalent to the obsolete RG2012P-6341-B-T1. Both parts share identical electrical specifications: 6.34 kOhms ±0.1% tolerance, 0.125W power rating, ±25ppm/°C temperature coefficient, and full AEC-Q200 automotive qualification. The primary difference is product status (active vs. obsolete) and packaging format (Tape & Reel vs. bulk). This part is the recommended first choice for direct replacement.

ERA-6AEB6341V (Panasonic) provides an alternative direct equivalent from a different manufacturer. It matches all critical electrical parameters and maintains AEC-Q200 compliance. This option is suitable when Susumu parts are unavailable.

Upgraded Specifications (Improved Performance):

RG2012V series parts (RG2012V-6341-B-T5, RG2012V-6341-P-T1, RG2012V-6341-W-T1, RG2012V-6341-W-T5) offer superior temperature coefficient performance (±5ppm/°C) compared to the original ±25ppm/°C specification. These upgrades are compatible with the original design and provide enhanced stability across the operating temperature range. Selection among RG2012V variants depends on tolerance requirements: ±0.1% (B-series), ±0.05% (W-series), or ±0.02% (P-series).

RG2012N-6341-B-T5 and RG2012N-6341-W-T1 offer intermediate temperature coefficient improvement (±10ppm/°C) with tolerance options of ±0.1% or ±0.05%.

Higher Power Rating Alternative:

8-2176092-7 (TE Connectivity) provides 0.25W (1/4W) power rating in the same 0805 package. This part is suitable for applications requiring increased thermal margin. However, this part does not carry AEC-Q200 automotive qualification. Use this option only when automotive compliance is not required and higher power dissipation capacity is beneficial.

Selection Criteria:

For direct replacement in automotive applications: RG2012P-6341-B-T5 or ERA-6AEB6341V
For improved temperature stability: RG2012V series variants
For tighter tolerance requirements: RG2012V-6341-P-T1 (±0.02%) or RG2012N-6341-W-T1 (±0.05%)
For non-automotive applications with higher power needs: 8-2176092-7

All recommended substitutes maintain ROHS3 compliance, Moisture Sensitivity Level 1 (Unlimited), and identical mechanical dimensions (0.079" L × 0.049" W, 0.50mm maximum seated height).

Frequently Asked Questions (FAQ)

Q: Can RG2012P-6341-B-T5 be used as a direct replacement for RG2012P-6341-B-T1?

A: Yes. RG2012P-6341-B-T5 is electrically and mechanically identical to RG2012P-6341-B-T1. Both parts have 6.34 kOhms ±0.1% resistance, 0.125W power rating, ±25ppm/°C temperature coefficient, and AEC-Q200 automotive qualification. The difference is product status (active vs. obsolete) and packaging format. This is the recommended direct replacement.

Q: What is the difference between Susumu RG2012P and RG2012V series?

A: The primary difference is temperature coefficient. RG2012P series has ±25ppm/°C, while RG2012V series has ±5ppm/°C. Both series maintain identical resistance values, tolerance options, power ratings, and package dimensions. RG2012V provides superior temperature stability and is suitable for precision applications requiring lower drift across the -55°C to 155°C operating range.

Q: Can I use ERA-6AEB6341V instead of a Susumu part?

A: Yes. ERA-6AEB6341V from Panasonic is electrically equivalent to RG2012P-6341-B-T1 and RG2012P-6341-B-T5. It provides 6.34 kOhms ±0.1% resistance, 0.125W power rating, ±25ppm/°C temperature coefficient, and AEC-Q200 automotive qualification. This part is suitable for direct substitution when Susumu components are unavailable.

Q: Is the TE Connectivity 8-2176092-7 a suitable replacement?

A: 8-2176092-7 is electrically compatible (6.34 kOhms ±0.1%, ±25ppm/°C) but differs in two aspects: it provides 0.25W (1/4W) power rating instead of 0.125W, and it does not carry AEC-Q200 automotive qualification. Use this part only in non-automotive applications where higher power dissipation capacity is required or beneficial.

Q: What does tolerance ±0.1%, ±0.05%, and ±0.02% mean for substitution?

A: Tolerance specifies the maximum deviation from the nominal 6.34 kOhms resistance value. ±0.1% allows ±6.34 Ohms deviation, ±0.05% allows ±3.17 Ohms, and ±0.02% allows ±1.27 Ohms. Tighter tolerances (±0.05%, ±0.02%) are compatible replacements for ±0.1% specifications because they provide equal or better accuracy. Reverse substitution (using ±0.1% where ±0.02% is required) is not acceptable.

Q: What is the significance of temperature coefficient in resistor selection?

A: Temperature coefficient (ppm/°C) indicates how much the resistance value changes per degree Celsius. Lower values indicate better stability. The original part has ±25ppm/°C; RG2012V series has ±5ppm/°C. In applications operating across the full -55°C to 155°C range (210°C span), the original part can drift up to ±52.5 Ohms, while RG2012V drifts only ±10.5 Ohms. Substituting with lower temperature coefficient parts improves circuit stability.

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

A: Yes. All active substitute parts listed are available in Tape & Reel (TR) packaging format. The original RG2012P-6341-B-T1 was available in bulk packaging. Tape & Reel format is standard for automated assembly and is fully compatible with the original design.

Q: Do all substitute parts maintain AEC-Q200 automotive qualification?

A: All Susumu RG series parts and Panasonic ERA-6AEB6341V maintain AEC-Q200 automotive qualification. The TE Connectivity 8-2176092-7 does not carry this rating. For automotive applications, use only AEC-Q200 qualified parts.

Q: Can I mix different substitute parts in the same circuit board?

A: Yes, provided all parts meet the circuit's electrical requirements. However, for consistency and simplified inventory management, use a single part number across the design. If mixing is necessary, ensure all parts meet the most stringent tolerance and temperature coefficient requirements of the circuit.

Q: What is Moisture Sensitivity Level (MSL) 1?

A: MSL 1 indicates unlimited shelf life and no special moisture handling requirements. All substitute parts have MSL 1, meaning they can be stored and handled under standard conditions without moisture-related degradation. This is the most favorable moisture sensitivity rating.
