Frequently Asked Questions (FAQ)

Q: Can RG1005P-5491-W-T5 be used as a direct replacement for RG1005P-5491-W-T1?

A: Yes. The RG1005P-5491-W-T5 provides direct functional equivalence. Both parts share identical resistance value (5.49 kOhms), tolerance (±0.05%), power rating (0.063W), package type (0402), and automotive AEC-Q200 qualification. The difference in packaging format (tape & reel) does not affect electrical or mechanical performance.

Q: What is the difference between RG1005P-5491-W-T5 and RG1005N-5491-W-T1?

A: The primary difference is temperature coefficient. RG1005P-5491-W-T5 has a temperature coefficient of ±25ppm/°C, while RG1005N-5491-W-T1 has ±10ppm/°C. All other electrical specifications, mechanical dimensions, and compliance ratings are identical. The RG1005N-5491-W-T1 provides enhanced temperature stability for applications requiring tighter performance across the operating temperature range.

Q: Are both substitute parts in active production?

A: Yes. Both RG1005P-5491-W-T5 and RG1005N-5491-W-T1 are classified as active products with current inventory availability. The original RG1005P-5491-W-T1 is obsolete, making these active alternatives necessary for ongoing production requirements.

Q: Do the substitute parts meet automotive standards?

A: Yes. Both substitute parts carry AEC-Q200 automotive qualification, anti-sulfur coating, and are suitable for automotive applications across the operating temperature range of -55°C to 155°C.

Q: What is the significance of the packaging format difference?

A: The packaging format (tape & reel) affects handling and assembly processes but does not impact electrical performance or mechanical compatibility. Both substitute parts are supplied in tape & reel format, which is standard for high-volume automated assembly operations.

Q: Are the substitute parts RoHS3 compliant?

A: Yes. Both RG1005P-5491-W-T5 and RG1005N-5491-W-T1 are RoHS3 compliant with moisture sensitivity level 1 (unlimited), matching the environmental compliance profile of the original component.

Q: Which substitute should be selected for new designs?

A: For new designs, RG1005N-5491-W-T1 is the preferred selection due to its enhanced temperature coefficient (±10ppm/°C) and active production status. For direct replacement of existing designs, RG1005P-5491-W-T5 provides equivalent performance to the original specification.
