Engineering Selection Recommendations

Direct Replacement (Identical Specifications):

RG1608P-9090-B-T5 is the direct active equivalent to RG1608P-9090-B-T1. Both parts share identical electrical specifications: 909 Ohms ±0.1% tolerance, 0.1W power rating, ±25ppm/°C temperature coefficient, and 0603 package. The primary difference is packaging format (Tape & Reel vs. bulk) and active product status. This part is recommended for direct substitution in new designs and production.

Enhanced Specifications (Superior Performance):

Parts with improved temperature coefficient specifications provide enhanced stability across the operating temperature range:

RG1608N series (±10ppm/°C): Available in ±0.1%, ±0.05%, and ±0.02% tolerance grades. Suitable for applications requiring improved thermal stability while maintaining ±25ppm/°C baseline performance.
RG1608V series (±5ppm/°C): Highest precision temperature coefficient performance. Available in ±0.1%, ±0.05%, and ±0.02% tolerance grades. Recommended for precision measurement and calibration circuits.

Cross-Manufacturer Alternative:

ERA-3AEB9090V (Panasonic Electronic Components) provides equivalent electrical performance with 909 Ohms ±0.1% tolerance and ±25ppm/°C temperature coefficient. This part offers significantly higher inventory availability (39600 Pcs) and maintains AEC-Q200 automotive qualification. Physical dimensions differ slightly (0.022" maximum seated height vs. 0.020" for Susumu parts), which is within standard PCB assembly tolerances.

Product Status Consideration:

All substitute parts listed carry active product status, ensuring long-term availability and supply chain continuity. The original RG1608P-9090-B-T1 is classified as obsolete and should be replaced in new designs.

Frequently Asked Questions (FAQ)

Q: Can RG1608P-9090-B-T5 be used as a direct replacement for RG1608P-9090-B-T1?

A: Yes. Both parts have identical electrical specifications (909 Ohms ±0.1%, 0.1W, ±25ppm/°C) and package type (0603). The primary difference is packaging format and product status. RG1608P-9090-B-T5 is active and recommended for new designs.

Q: What is the difference between RG1608P, RG1608N, and RG1608V series?

A: The letter designation indicates temperature coefficient performance. RG1608P has ±25ppm/°C, RG1608N has ±10ppm/°C, and RG1608V has ±5ppm/°C. All other specifications remain identical for parts with the same resistance and tolerance values.

Q: Can I substitute ERA-3AEB9090V for RG1608P-9090-B-T1?

A: Yes. ERA-3AEB9090V meets all mandatory compatibility parameters: 909 Ohms ±0.1%, 0.1W power rating, 0603 package, AEC-Q200 qualification, and -55°C to 155°C operating range. Physical height differs by 0.002" (0.022" vs. 0.020"), which is acceptable for standard PCB assembly.

Q: What tolerance grades are available as substitutes?

A: Substitute parts are available in three tolerance grades: ±0.1% (standard), ±0.05% (intermediate precision), and ±0.02% (high precision). All grades maintain the same 909 Ohm resistance value and 0603 package.

Q: Does the anti-sulfur feature affect substitution compatibility?

A: Anti-sulfur coating is present in all Susumu RG series parts but not specified in the Panasonic ERA-3AEB9090V. This feature does not prevent substitution; it represents an additional protective characteristic in Susumu parts.

Q: What is the difference between T1 and T5 packaging designations?

A: T1 and T5 designations indicate different tape and reel configurations for automated assembly. Both are Tape & Reel formats suitable for pick-and-place equipment. Selection depends on assembly line compatibility.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed are RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Which substitute part offers the best temperature stability?

A: RG1608V series parts (RG1608V-9090-B-T5, RG1608V-9090-P-T1, RG1608V-9090-W-T1) offer the lowest temperature coefficient at ±5ppm/°C, providing superior thermal stability across the -55°C to 155°C operating range.
