Engineering Selection Recommendations
Primary Direct Substitute (Identical Manufacturer): RG1005P-3571-B-T5 (Susumu) is the direct replacement for the obsolete RG1005P-3571-B-T1. Both parts share identical electrical specifications, automotive AEC-Q200 qualification, anti-sulfur coating, and operating temperature range. The only difference is packaging format (Tape & Reel vs. unspecified) and active product status. This part is recommended for applications requiring continuity with the original design.
Primary Direct Substitute (Alternative Manufacturers): ERA-2AEB3571X (Panasonic) and RT0402BRD073K57L (YAGEO) are functionally equivalent direct substitutes. Both maintain ±0.1% tolerance, 0.063W power rating, ±25ppm/°C temperature coefficient, and -55°C to 155°C operating range. ERA-2AEB3571X includes automotive AEC-Q200 qualification matching the original part. RT0402BRD073K57L offers Cut Tape packaging as an alternative to Tape & Reel format.
Upgrade Substitutes (Enhanced Specifications): RG1005N-3571-B-T5 and RG1005N-3571-W-T1 (Susumu) provide improved temperature coefficient performance (±10ppm/°C vs ±25ppm/°C). RG1005N-3571-W-T1 additionally offers tighter tolerance (±0.05% vs ±0.1%). RN73C1E3K57BTDF (TE Connectivity) provides ±10ppm/°C temperature coefficient with ±0.1% tolerance. These upgrades are suitable for applications requiring enhanced stability over temperature.
Higher Power Rating Substitute: TNPW04023K57BEED (Vishay Dale) provides 0.13W power rating (double the original 0.063W) while maintaining all other electrical parameters. This part includes automotive AEC-Q200 qualification and extended operating temperature to 175°C. Selection of this part is appropriate only when increased power dissipation capability is required.
Operating Temperature Limitation: MCS04020D3571BE100 (Vishay) specifies maximum operating temperature of 125°C, which is below the original part's 155°C upper limit. This part is not recommended for applications requiring the full -55°C to 155°C temperature range.
Non-Automotive Applications: CPF0402B3K57E1 (TE Connectivity) lacks automotive AEC-Q200 qualification but maintains all electrical specifications. This part is suitable for non-automotive precision applications where AEC-Q200 certification is not required.
Frequently Asked Questions (FAQ)
Q: Can RG1005P-3571-B-T5 be used as a direct replacement for RG1005P-3571-B-T1?
A: Yes. Both parts are manufactured by Susumu with identical electrical specifications: 3.57 kOhms ±0.1%, 0.063W power rating, ±25ppm/°C temperature coefficient, and -55°C to 155°C operating range. Both include anti-sulfur coating and automotive AEC-Q200 qualification. The primary difference is packaging format and product status (active vs. obsolete).
Q: What is the difference between direct substitutes and upgrade substitutes?
A: Direct substitutes maintain identical electrical specifications to the original part. Upgrade substitutes exceed the original specification in one or more parameters, such as tighter tolerance (±0.05% vs ±0.1%) or improved temperature coefficient (±10ppm/°C vs ±25ppm/°C). Upgrade substitutes are backward compatible but provide enhanced performance.
Q: Are all substitute parts automotive-qualified?
A: No. ERA-2AEB3571X and TNPW04023K57BEED include automotive AEC-Q200 qualification. CPF0402B3K57E1, RT0402BRD073K57L, MCS04020D3571BE100, and RN73C1E3K57BTDF do not carry AEC-Q200 certification. For automotive applications, select parts with explicit AEC-Q200 rating.
Q: Can TNPW04023K57BEED be used in place of the original part?
A: TNPW04023K57BEED is electrically compatible but differs in power rating (0.13W vs 0.063W) and maximum operating temperature (175°C vs 155°C). Use this part only when increased power dissipation capability is required. The higher power rating does not create compatibility issues in circuits designed for 0.063W resistors.
Q: What is the significance of the 0402 package specification?
A: The 0402 (1005 Metric) package is a standardized surface-mount resistor size measuring 1.00mm × 0.50mm. All substitute parts listed maintain this identical package footprint, ensuring mechanical compatibility with printed circuit board layouts designed for the original part.
Q: Does tolerance affect substitutability?
A: Tolerance affects circuit performance but not physical substitutability. The original part specifies ±0.1% tolerance. Substitute parts with ±0.1% tolerance maintain identical accuracy. Upgrade substitutes with ±0.05% tolerance provide tighter accuracy and are suitable for precision applications but are not required for circuits designed around ±0.1% tolerance.
Q: What is the difference between Tape & Reel and Cut Tape packaging?
A: Both are standard surface-mount packaging formats. Tape & Reel (TR) provides components on continuous tape in reel format for automated assembly. Cut Tape (CT) provides components on tape segments. Both formats are compatible with standard pick-and-place assembly equipment. Selection depends on assembly process requirements and supplier availability.
Q: Why does MCS04020D3571BE100 have a lower maximum operating temperature?
A: MCS04020D3571BE100 specifies -55°C to 125°C operating range, which is 30°C below the original part's 155°C upper limit. This part is not suitable for applications requiring operation at temperatures between 125°C and 155°C. Verify application temperature requirements before selecting this substitute.
Q: Are all substitute parts RoHS3 compliant?
A: Yes. All substitute parts listed carry ROHS3 Compliant status, matching the original part's environmental compliance. All parts also maintain MSL 1 (Unlimited) moisture sensitivity rating.
