Engineering Selection Recommendations

Direct Equivalent (Same Specifications):

RG1005P-3401-B-T5 is the direct equivalent to RG1005P-3401-B-T1. Both parts share identical electrical specifications (3.4 kΩ, ±0.1%, ±25ppm/°C) and mechanical package (0402). The primary difference is packaging format (Tape & Reel vs. bulk). RG1005P-3401-B-T5 is active and recommended as the primary replacement.

Cross-Manufacturer Direct Equivalents:

ERA-2AEB3401X (Panasonic), RT0402BRD073K4L (YAGEO), and CPF0402B3K4E1 (TE Connectivity) provide identical electrical and mechanical specifications with active product status. All three are ROHS3 compliant and suitable for direct substitution. ERA-2AEB3401X includes AEC-Q200 automotive qualification matching the original part.

Enhanced Performance Alternatives:

RG1005N-3401-B-T5 and RN73C1E3K4BTDF offer improved temperature coefficient (±10ppm/°C vs. ±25ppm/°C), providing superior stability across the operating temperature range while maintaining all other specifications.

RG1005N-3401-W-T1 and RG1005P-3401-W-T5 provide tighter tolerance (±0.05% vs. ±0.1%), suitable for applications requiring enhanced precision.

Higher Power Rating Alternative:

TNPW04023K40BEED (Vishay Dale) provides 0.13W power rating (double the original 0.063W) with extended operating temperature to 175°C, anti-sulfur coating, AEC-Q200 qualification, and moisture resistance. This part is suitable for applications with higher thermal dissipation requirements.

Limited Temperature Range Alternative:

MCS04020D3401BE100 (Vishay) operates to 125°C maximum (vs. 155°C), making it unsuitable for applications requiring the full -55°C to 155°C range. Selection should be restricted to designs with maximum operating temperature of 125°C or below.

Frequently Asked Questions (FAQ)

Q: Can RG1005P-3401-B-T5 replace RG1005P-3401-B-T1 directly?

A: Yes. RG1005P-3401-B-T5 is a direct equivalent with identical resistance (3.4 kΩ), tolerance (±0.1%), power rating (0.063W), temperature coefficient (±25ppm/°C), and operating temperature range (-55°C to 155°C). The only difference is packaging format (Tape & Reel). Both are ROHS3 compliant with MSL 1 rating.

Q: What is the difference between Susumu RG series parts?

A: RG1005P-3401-B-T5 and RG1005N-3401-B-T5 differ in temperature coefficient: P-series has ±25ppm/°C while N-series has ±10ppm/°C. The W-suffix variants (RG1005N-3401-W-T1 and RG1005P-3401-W-T5) have tighter tolerance (±0.05% vs. ±0.1%). Selection depends on precision and stability requirements.

Q: Is TNPW04023K40BEED compatible with the original part?

A: TNPW04023K40BEED is mechanically and electrically compatible in the 0402 package with matching 3.4 kΩ resistance and ±0.1% tolerance. However, it provides double the power rating (0.13W vs. 0.063W) and extended temperature range (-55°C to 175°C). It is suitable for designs with higher thermal dissipation or extended temperature requirements.

Q: Can I use MCS04020D3401BE100 in place of RG1005P-3401-B-T1?

A: MCS04020D3401BE100 is suitable only for applications with maximum operating temperature of 125°C or below. The original part and most alternatives support -55°C to 155°C. If your design requires operation above 125°C, MCS04020D3401BE100 is not appropriate.

Q: What are the key parameters for substitution?

A: Critical parameters are resistance (3.4 kΩ), tolerance (±0.1% or tighter), package (0402), composition (thin film), and RoHS compliance. Temperature coefficient, power rating, and operating temperature range can be equal or improved. Automotive AEC-Q200 and anti-sulfur features are beneficial but not mandatory for substitution.

Q: Which substitute offers the best temperature stability?

A: RG1005N-3401-B-T5 and RN73C1E3K4BTDF both offer ±10ppm/°C temperature coefficient, providing superior stability compared to the original ±25ppm/°C specification. Both maintain identical 3.4 kΩ resistance and 0402 package.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the original RG1005P-3401-B-T1 environmental specifications.
