Frequently Asked Questions (FAQ)

Q: Can RG1005P-4872-B-T5 be used as a direct replacement for RG1005P-4872-B-T1?

A: Yes. The RG1005P-4872-B-T5 is electrically and mechanically identical to the obsolete RG1005P-4872-B-T1. Both feature 48.7 kOhms ±0.1% tolerance, 0.063W power rating, ±25ppm/°C temperature coefficient, and -55°C to 155°C operating range. The primary difference is product status (active vs obsolete) and packaging format (Tape & Reel vs bulk).

Q: What is the difference between RG1005P and RG1005N series?

A: The RG1005N series offers improved temperature coefficient (±10ppm/°C) compared to RG1005P (±25ppm/°C). Both series maintain identical resistance, tolerance, power rating, and package specifications. Selection depends on application requirements for temperature stability.

Q: Can TNPW040248K7BEED replace RG1005P-4872-B-T1 in all applications?

A: TNPW040248K7BEED is electrically compatible but features enhanced specifications: 0.13W power rating (vs 0.063W) and -55°C to 175°C operating range (vs -55°C to 155°C). It is suitable for replacement in all applications where the original part was used. The higher power rating provides additional thermal margin without affecting circuit performance.

Q: Why is MCS04020D4872BE100 not recommended?

A: The MCS04020D4872BE100 has a maximum operating temperature of 125°C, which does not meet the original specification requirement of 155°C. This part is unsuitable for applications requiring the full -55°C to 155°C temperature range.

Q: Are cross-manufacturer substitutes (YAGEO, Panasonic, TE Connectivity) acceptable?

A: Cross-manufacturer substitutes with identical electrical specifications (48.7 kOhms ±0.1%, 0.063W, ±25ppm/°C, -55°C to 155°C) are electrically compatible. Selection should consider application requirements: automotive applications benefit from AEC-Q200 qualified parts (Panasonic ERA-2AEB4872X, Susumu RG series), while non-automotive applications accept any electrically equivalent part.

Q: What is the significance of the packaging designation (T1 vs T5)?

A: T1 and T5 designations indicate different packaging formats. T1 typically represents bulk or cut-tape packaging, while T5 represents Tape & Reel (TR) format. Both formats contain identical components; packaging format selection depends on assembly process requirements and volume handling.

Q: Can the ±0.05% tolerance parts (RG1005N-4872-W-T1, RG1005P-4872-W-T5) be used interchangeably with ±0.1% parts?

A: Yes. Parts with ±0.05% tolerance are tighter specifications and fully backward compatible with designs requiring ±0.1% tolerance. The ±0.05% parts provide enhanced accuracy and are suitable for any application accepting ±0.1% tolerance.
