Engineering Selection Recommendations

Primary Direct Substitute: RG2012N-241-B-T5 is the recommended direct replacement for the obsolete RG2012N-241-B-T1. Both parts are manufactured by Susumu, share identical electrical specifications (240 Ohms ±0.1%, ±10ppm/°C), and maintain full AEC-Q200 automotive qualification. The primary difference is packaging format (Tape & Reel versus bulk) and active production status. This part is suitable for direct board-level substitution without design modification.

Alternative Direct Substitute: RG2012V-241-B-T5 provides equivalent electrical performance with improved temperature coefficient (±5ppm/°C versus ±10ppm/°C), maintaining the ±0.1% tolerance specification. This part is appropriate for applications where enhanced thermal stability is beneficial.

Upgrade Substitutes for Enhanced Precision: RG2012N-241-W-T1, RG2012N-241-W-T5, RG2012V-241-W-T1, and RG2012V-241-W-T5 offer tighter tolerance specifications (±0.05%) while maintaining or improving temperature coefficient performance. These parts are suitable for precision analog circuits, measurement instrumentation, and applications requiring reduced tolerance stack-up.

Premium Upgrade Substitute: RG2012V-241-P-T1 provides the highest precision available (±0.02% tolerance, ±5ppm/°C temperature coefficient). This part is appropriate for precision reference circuits, calibration networks, and high-accuracy signal conditioning applications.

Cross-Manufacturer Alternatives: ERA-6AEB241V (Panasonic) and RT0805WRB07240RL (YAGEO) provide functional equivalence with identical resistance, tolerance, and package specifications. ERA-6AEB241V maintains AEC-Q200 qualification. RT0805WRB07240RL offers ±0.05% tolerance but does not carry AEC-Q200 automotive rating; use is restricted to non-automotive applications.

Frequently Asked Questions (FAQ)

Q: Can RG2012N-241-B-T5 be used as a direct replacement for RG2012N-241-B-T1?

A: Yes. Both parts are manufactured by Susumu with identical electrical specifications: 240 Ohms ±0.1%, 0.125W power rating, ±10ppm/°C temperature coefficient, and AEC-Q200 automotive qualification. The primary difference is packaging format (Tape & Reel versus bulk). RG2012N-241-B-T5 is in active production status and is the recommended replacement for the obsolete RG2012N-241-B-T1.

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

A: The RG2012V series provides superior temperature coefficient performance (±5ppm/°C) compared to the RG2012N series (±10ppm/°C). Both series maintain identical resistance values, tolerance specifications, and AEC-Q200 qualification. RG2012V parts are suitable for applications requiring enhanced thermal stability.

Q: Can I use RG2012N-241-W-T1 (±0.05% tolerance) in place of RG2012N-241-B-T1 (±0.1% tolerance)?

A: Yes. RG2012N-241-W-T1 provides tighter tolerance (±0.05%) than the original specification (±0.1%), making it a compatible upgrade. The part maintains identical resistance value, power rating, temperature coefficient, and AEC-Q200 qualification. Tighter tolerance specifications do not create compatibility issues in circuit applications designed for the original tolerance.

Q: What is the significance of the T1 and T5 suffixes in Susumu part numbers?

A: The T1 and T5 suffixes indicate packaging format. T1 denotes bulk or tube packaging, while T5 denotes Tape & Reel (TR) packaging. Both formats contain identical components; the difference is in delivery and handling method. T5 (Tape & Reel) is standard for automated assembly processes.

Q: Is ERA-6AEB241V suitable for automotive applications?

A: Yes. ERA-6AEB241V is manufactured by Panasonic and carries AEC-Q200 automotive qualification. It provides equivalent electrical specifications (240 Ohms ±0.1%, 0.125W) and is suitable for automotive circuit applications. The temperature coefficient is ±25ppm/°C, which is less stringent than the original RG2012N-241-B-T1 specification (±10ppm/°C).

Q: Can RT0805WRB07240RL be used in automotive applications?

A: RT0805WRB07240RL is manufactured by YAGEO and does not carry AEC-Q200 automotive qualification. Use of this part is restricted to non-automotive applications. For automotive circuit requirements, select from Susumu RG series or Panasonic ERA-6A series parts, both of which maintain AEC-Q200 qualification.

Q: What is the maximum height difference between substitute parts?

A: The original RG2012N-241-B-T1 has a maximum seated height of 0.020" (0.50mm). Panasonic ERA-6AEB241V has a maximum seated height of 0.024" (0.60mm), and YAGEO RT0805WRB07240RL also has a maximum seated height of 0.024" (0.60mm). All Susumu RG series substitutes maintain the 0.020" (0.50mm) maximum height. Height differences of 0.004" (0.10mm) are within standard PCB design tolerances for 0805 package components.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance status. All parts also carry Moisture Sensitivity Level 1 (Unlimited) rating and are REACH Unaffected.
