Parameter Comparison

Engineering Selection Recommendations

RG1005P-510-W-T5 (Direct Substitute): This part provides direct functional equivalence to the RG1005P-510-W-T1 with identical electrical specifications and mechanical dimensions. The primary distinction is packaging configuration (Tape & Reel format) and active product status. This substitute is suitable for applications where the original part's packaging specification is not a constraint. The part maintains full AEC-Q200 automotive qualification and ROHS3 compliance.

RG1005N-510-W-T1 (Upgrade Substitute): This part offers enhanced performance characteristics through a reduced temperature coefficient of ±10ppm/°C compared to the original ±25ppm/°C specification. All other electrical and mechanical parameters remain equivalent. The RG1005N-510-W-T1 is classified as active with higher inventory availability (983 Pcs). This substitute is recommended for applications requiring improved temperature stability while maintaining full automotive AEC-Q200 qualification and ROHS3 compliance.

Both substitutes maintain identical resistance value, tolerance, power rating, package dimensions, and compliance certifications. Selection between alternatives depends on packaging requirements and temperature stability performance criteria.

Frequently Asked Questions (FAQ)

Q: Can the RG1005P-510-W-T5 be used as a direct replacement for the RG1005P-510-W-T1?

A: Yes. The RG1005P-510-W-T5 provides complete electrical and mechanical equivalence. The primary difference is packaging format (Tape & Reel). Both parts share identical resistance (51 Ohms), tolerance (±0.05%), power rating (0.063W), temperature coefficient (±25ppm/°C), and 0402 package dimensions. Both are AEC-Q200 qualified and ROHS3 compliant.

Q: What is the difference between the RG1005P-510-W-T1 and RG1005N-510-W-T1?

A: The RG1005N-510-W-T1 features a superior temperature coefficient of ±10ppm/°C versus the original ±25ppm/°C. All other specifications—resistance, tolerance, power rating, package type, and compliance ratings—are identical. The improved temperature coefficient provides enhanced stability across the -55°C to 155°C operating range.

Q: Are both substitute parts suitable for automotive applications?

A: Yes. Both RG1005P-510-W-T5 and RG1005N-510-W-T1 carry AEC-Q200 automotive qualification and anti-sulfur coating, meeting automotive reliability standards equivalent to the original part.

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

A: The suffix designates packaging configuration. T1 and T5 refer to different tape and reel specifications or bulk packaging formats. Both maintain identical component specifications and are suitable for automated assembly processes.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes, provided the PCB design accommodates the 0402 (1005 Metric) package format. All three parts share identical physical dimensions (0.039" L x 0.020" W, 1.00mm x 0.50mm) and mounting characteristics, enabling direct substitution at the assembly level.

Q: Is the RG1005N-510-W-T1 a superior choice for all applications?

A: The RG1005N-510-W-T1 offers improved temperature stability due to its lower temperature coefficient (±10ppm/°C). Selection depends on application requirements. For circuits where temperature coefficient performance is not critical, either substitute provides equivalent functionality.

Q: What is the moisture sensitivity level, and does it affect handling?

A: All three parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard component handling procedures apply without special moisture control requirements.
