Engineering Selection Recommendations

RG1608N-682-W-T1 (Susumu): This part is a direct substitute for the RG1608P-682-W-T1. Both components are manufactured by Susumu and share identical electrical specifications, package dimensions, and compliance certifications. The RG1608N-682-W-T1 features a lower temperature coefficient (±10ppm/°C versus ±25ppm/°C), which provides improved temperature stability. Both parts maintain AEC-Q200 automotive qualification and ROHS3 compliance. Selection between these two Susumu variants depends on application-specific temperature stability requirements.

ERA-3ARW682V (Panasonic Electronic Components): This part qualifies as a substitute based on matching electrical parameters, package type, and compliance ratings. The ERA-3ARW682V is manufactured by Panasonic and maintains the same 6.8 kOhms resistance, ±0.05% tolerance, 0.1W power rating, and AEC-Q200 automotive qualification. The maximum seated height is 0.022" (0.55mm) compared to 0.020" (0.50mm) for the RG1608P-682-W-T1. This 0.002" (0.05mm) difference is within typical PCB assembly tolerances and does not preclude substitution. The ERA-3ARW682V also features ±10ppm/°C temperature coefficient and maintains ROHS3 compliance and MSL 1 rating.

All three parts are active products with current manufacturing status and established supply availability.

Frequently Asked Questions (FAQ)

Q: Can RG1608N-682-W-T1 be used as a direct replacement for RG1608P-682-W-T1?

A: Yes. Both parts are manufactured by Susumu with identical resistance (6.8 kOhms), tolerance (±0.05%), power rating (0.1W), package (0603), and compliance certifications (AEC-Q200, ROHS3). The RG1608N-682-W-T1 features improved temperature coefficient performance (±10ppm/°C versus ±25ppm/°C).

Q: What is the difference between the Susumu RG1608P and RG1608N series?

A: The primary difference is temperature coefficient specification. The RG1608P-682-W-T1 has ±25ppm/°C, while the RG1608N-682-W-T1 has ±10ppm/°C. Both maintain identical electrical values, package dimensions, and automotive qualifications.

Q: Is the ERA-3ARW682V compatible with the RG1608P-682-W-T1 in terms of PCB assembly?

A: Yes. The ERA-3ARW682V has a maximum seated height of 0.022" (0.55mm) compared to 0.020" (0.50mm) for the RG1608P-682-W-T1. This 0.002" (0.05mm) difference is within standard PCB assembly tolerances and does not affect component placement or functionality.

Q: Do all three parts meet automotive qualification requirements?

A: Yes. The RG1608P-682-W-T1, RG1608N-682-W-T1, and ERA-3ARW682V all carry AEC-Q200 automotive qualification and are suitable for automotive applications.

Q: Are there any differences in environmental compliance between these parts?

A: No. All three parts are ROHS3 compliant, REACH unaffected, and classified as MSL 1 (Unlimited moisture sensitivity level). Environmental compliance is equivalent across all substitutes.

Q: Can these parts be used interchangeably in high-precision applications?

A: The RG1608N-682-W-T1 and ERA-3ARW682V are preferred for high-precision applications due to their ±10ppm/°C temperature coefficient compared to the RG1608P-682-W-T1 at ±25ppm/°C. All three maintain ±0.05% resistance tolerance.

Q: What is the packaging format for all three parts?

A: All three parts are supplied in Tape & Reel (TR) format in 0603 (1608 Metric) package configuration with 2 terminations.
