Parameter Comparison

Engineering Selection Recommendations

RG1608N-184-B-T5 (Direct Equivalent)

This part provides direct electrical and mechanical equivalence to the RG1608N-184-B-T1. Both components share identical tolerance (±0.1%), temperature coefficient (±10ppm/°C), and all critical electrical specifications. The primary difference is product status (Active vs. Obsolete) and packaging format (Tape & Reel vs. Bulk). This substitute is suitable for direct replacement in all applications where the original part was specified.

RG1608P-184-B-T5 (Direct Equivalent with Relaxed Temperature Coefficient)

This part maintains all critical electrical parameters including 180 kOhms resistance and ±0.1% tolerance. The temperature coefficient specification is ±25ppm/°C compared to ±10ppm/°C in the main part. This relaxation in temperature stability does not affect compliance with AEC-Q200 automotive qualification. This substitute is suitable for applications where the tighter temperature coefficient of the original part is not a design requirement.

RG1608N-184-W-T5 (Upgrade Option)

This part offers improved tolerance specification at ±0.05% compared to ±0.1% in the main part, while maintaining identical temperature coefficient (±10ppm/°C) and all other electrical characteristics. The enhanced tolerance provides greater precision for applications requiring tighter resistance value control. This upgrade option is suitable for designs where improved accuracy is beneficial.

All substitute parts maintain ROHS3 compliance, AEC-Q200 automotive qualification, anti-sulfur coating, and identical mechanical dimensions. Selection between direct equivalents and the upgrade option depends on tolerance and temperature coefficient requirements specific to the application circuit.

Frequently Asked Questions (FAQ)

Q: Can RG1608N-184-B-T5 be used as a direct replacement for RG1608N-184-B-T1?

A: Yes. Both parts share identical resistance (180 kOhms), tolerance (±0.1%), power rating (0.1W), package (0603), temperature coefficient (±10ppm/°C), and operating temperature range (-55°C ~ 155°C). The primary difference is product status and packaging format. Electrical performance is equivalent.

Q: What is the difference between RG1608N-184-B-T5 and RG1608P-184-B-T5?

A: Both parts are direct equivalents with identical resistance, tolerance, and power rating. The difference is temperature coefficient: RG1608N-184-B-T5 has ±10ppm/°C while RG1608P-184-B-T5 has ±25ppm/°C. Selection depends on whether the tighter temperature stability of the N-series is required for the application.

Q: What does the upgrade option RG1608N-184-W-T5 provide?

A: This part offers improved tolerance at ±0.05% compared to ±0.1% in the original part, while maintaining the same ±10ppm/°C temperature coefficient. It is suitable for applications requiring greater precision in resistance value.

Q: Are all substitute parts automotive qualified?

A: Yes. All substitute parts carry AEC-Q200 automotive qualification, anti-sulfur coating, and are suitable for automotive and high-reliability applications.

Q: What is the difference between bulk and Tape & Reel packaging?

A: The main part (RG1608N-184-B-T1) is supplied in bulk packaging, while all substitute parts are supplied in Tape & Reel (TR) format. Both packaging formats contain the same component; the difference is in handling and assembly convenience. Tape & Reel format is standard for automated assembly processes.

Q: Are all parts ROHS3 compliant?

A: Yes. The main part and all substitute parts are ROHS3 compliant and REACH unaffected, meeting environmental regulatory requirements.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes. All parts share identical mechanical dimensions (0.063" L x 0.031" W, 1.60mm x 0.80mm) and height (0.020" max), allowing direct PCB footprint compatibility.
