Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Packaging Variant): RG1005P-2101-W-T5 is the direct functional equivalent of RG1005P-2101-W-T1, differing only in packaging format (Tape & Reel versus bulk). This part maintains identical electrical specifications and temperature coefficient performance. Selection of this part is appropriate for applications requiring active product status with standard production packaging.

Enhanced Performance Alternatives: RG1005N-2101-W-T1, RG1005V-2101-W-T1, and RG1005V-2101-P-T1 are active alternatives offering improved temperature stability through reduced temperature coefficients (±10ppm/°C and ±5ppm/°C respectively). RG1005V-2101-P-T1 additionally provides tighter tolerance specification (±0.02%) for precision circuit applications. All three parts maintain full AEC-Q200 automotive compliance and identical mechanical compatibility.

Compliance Verification: All substitute parts carry ROHS3 compliance, AEC-Q200 automotive rating, and MSL 1 moisture sensitivity classification, ensuring direct substitution in automotive and industrial applications without design modification.

Frequently Asked Questions (FAQ)

Q: Can RG1005P-2101-W-T5 replace RG1005P-2101-W-T1 in production assembly? A: Yes. RG1005P-2101-W-T5 is electrically and mechanically identical to RG1005P-2101-W-T1. The difference is packaging format: T5 denotes Tape & Reel format suitable for automated pick-and-place assembly, while T1 denotes bulk packaging. Both parts have identical electrical performance and AEC-Q200 compliance.

Q: What is the difference between the temperature coefficient values across substitute parts? A: Temperature coefficient indicates resistance change per degree Celsius. RG1005P-2101-W-T1 and RG1005P-2101-W-T5 have ±25ppm/°C; RG1005N-2101-W-T1 has ±10ppm/°C; RG1005V-2101-W-T1 and RG1005V-2101-P-T1 have ±5ppm/°C. Lower values indicate better stability across temperature extremes. Selection depends on circuit precision requirements.

Q: Are all substitute parts suitable for automotive applications? A: Yes. All listed substitute parts carry AEC-Q200 automotive qualification and anti-sulfur construction, meeting automotive reliability standards. Operating temperature range remains -55°C to 155°C across all parts.

Q: What is the significance of tolerance differences between parts? A: Tolerance specifies the allowable deviation from nominal resistance value. RG1005P-2101-W-T1, RG1005P-2101-W-T5, RG1005N-2101-W-T1, and RG1005V-2101-W-T1 have ±0.05% tolerance. RG1005V-2101-P-T1 has ±0.02% tolerance, providing tighter resistance accuracy for precision analog circuits. Both tolerances are acceptable for standard applications.

Q: Is the 0402 package dimension identical across all substitute parts? A: Yes. All parts use 0402 (1005 Metric) package with identical dimensions: 0.039" L × 0.020" W (1.00mm × 0.50mm) and maximum seated height of 0.016" (0.40mm). Direct PCB footprint compatibility is maintained.

Q: Why is RG1005P-2101-W-T1 listed as obsolete? A: Product status reflects manufacturer production status. Active alternatives with identical or superior specifications are available. RG1005P-2101-W-T5 provides direct replacement with current manufacturing support.

Q: Can RG1005V-2101-P-T1 be used in place of RG1005P-2101-W-T1? A: Yes. RG1005V-2101-P-T1 is a direct substitute with enhanced specifications: tighter tolerance (±0.02% versus ±0.05%) and superior temperature stability (±5ppm/°C versus ±25ppm/°C). All other electrical and mechanical parameters remain compatible. This part is suitable for applications requiring higher precision.
