RG1005P-1072-B-T5 (Susumu) is the primary direct substitute. This part maintains identical electrical and mechanical specifications to the obsolete RG1005P-1072-B-T1, with the distinction of active product status and Tape & Reel packaging. Both parts carry automotive AEC-Q200 qualification and anti-sulfur coating.

ERA-2AEB1072X (Panasonic Electronic Components) provides an alternative direct substitute with equivalent specifications, AEC-Q200 rating, and higher inventory availability (33,722 units). This part is suitable for applications requiring automotive-grade reliability.

For Enhanced Performance (Upgrade Path):

RG1005N-1072-B-T5 (Susumu) offers improved temperature coefficient (±10ppm/°C versus ±25ppm/°C) while maintaining all other specifications. This upgrade is applicable to designs requiring superior temperature stability.

RG1005N-1072-W-T1 (Susumu) provides the tightest tolerance (±0.05%) with improved temperature coefficient (±10ppm/°C). This upgrade is suitable for precision measurement and calibration circuits.

RG1005P-1072-W-T5 (Susumu) combines tighter tolerance (±0.05%) with standard temperature coefficient (±25ppm/°C), offering a balanced upgrade path.

Operating Temperature Limitation:

MCS04020D1072BE100 (Vishay Beyschlag) has a maximum operating temperature of 125°C, which is below the original specification of 155°C. This part is not suitable for applications requiring the full temperature range of the original component.

Frequently Asked Questions (FAQ)

Q: Can RG1005P-1072-B-T5 be used as a direct replacement for RG1005P-1072-B-T1?

A: Yes. RG1005P-1072-B-T5 is a direct substitute with identical electrical specifications (10.7 kΩ ±0.1%, 0.063W, ±25ppm/°C, -55°C to 155°C). The primary difference is product status (Active versus Obsolete) and packaging format (Tape & Reel). No circuit redesign is required.

Q: What is the difference between the "B" and "N" series designations in Susumu RG1005 resistors?

A: Based on the provided specifications, the "N" series offers improved temperature coefficient (±10ppm/°C) compared to the "B" series (±25ppm/°C). Both series maintain identical resistance, tolerance, power rating, and package specifications.

Q: Can I use TNPW040210K7BEED as a substitute if my circuit is designed for 0.063W power rating?

A: TNPW040210K7BEED has a power rating of 0.13W, which exceeds the original 0.063W specification. This part is physically compatible and electrically equivalent. However, verify that the higher power rating does not introduce unintended thermal effects in your specific circuit application. The part is suitable for use in the same footprint.

Q: Are all substitute parts automotive-qualified?

A: No. ERA-2AEB1072X and TNPW040210K7BEED carry AEC-Q200 automotive qualification. CPF0402B10K7E1, RT0402BRD0710K7L, RN73C1E10K7BTDF, and MCS04020D1072BE100 do not carry automotive qualification. Select AEC-Q200 qualified parts for automotive applications.

Q: What is the significance of the "W" designation in part numbers like RG1005N-1072-W-T1?

A: Based on the provided specifications, the "W" designation indicates tighter tolerance (±0.05%) compared to parts without this designation (±0.1%). The "W" series is suitable for precision applications requiring higher accuracy.

Q: Is the 0402 package dimension identical across all substitute parts?

A: Yes. All substitute parts use the 0402 (1005 Metric) package with identical footprint dimensions (0.039" L × 0.020" W / 1.00mm × 0.50mm). Height variations exist: most parts are 0.014" to 0.016" (0.35mm to 0.40mm). These variations are within standard PCB assembly tolerances and do not affect interchangeability.

Q: Can I substitute RN73C1E10K7BTDF for RG1005P-1072-B-T1 in a temperature-sensitive application?

A: Yes, with consideration. RN73C1E10K7BTDF offers superior temperature coefficient (±10ppm/°C versus ±25ppm/°C), making it suitable for temperature-sensitive applications. However, this part does not carry AEC-Q200 automotive qualification. Verify compliance requirements for your application.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) packaging?

A: Both packaging formats contain identical components. Tape & Reel packaging is supplied on continuous reels suitable for automated assembly. Cut Tape packaging is supplied in smaller quantities on tape segments. Selection depends on production volume and assembly equipment compatibility. Electrical and mechanical specifications are identical.

Q: Why does MCS04020D1072BE100 have a lower maximum operating temperature (125°C) than the original part (155°C)?

A: This is a specification difference from the manufacturer. MCS04020D1072BE100 is rated to 125°C maximum, which is below the original RG1005P-1072-B-T1 specification of 155°C. This part is not suitable for applications requiring operation at temperatures between 125°C and 155°C.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed are ROHS3 compliant and carry Moisture Sensitivity Level 1 (Unlimited), matching the original component specifications.
