Frequently Asked Questions (FAQ)

Q: Can RG2012P-182-B-T5 be used as a direct replacement for RG2012P-182-C-T5?

A: Yes. Both parts share identical resistance (1.8 kOhms), power rating (0.125W), package (0805), operating temperature range (-55°C to 155°C), and AEC-Q200 qualification. The RG2012P-182-B-T5 offers improved tolerance (±0.1% versus ±0.25%), making it functionally superior while maintaining full compatibility.

Q: What is the difference between RG2012P and RG2012V series?

A: The RG2012V series features superior temperature coefficient performance (±5ppm/°C) compared to RG2012P (±25ppm/°C). Both series maintain identical resistance, power rating, and package specifications. Selection depends on circuit requirements for temperature stability; RG2012V is preferred for precision applications.

Q: Are all listed substitutes compatible with the original 0805 PCB footprint?

A: Yes. All substitute parts are specified as 0805 (2012 Metric) package type with identical footprint dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm). Maximum seated height varies slightly (0.020" to 0.024"), but all values remain within standard 0805 assembly tolerances and do not affect PCB layout compatibility.

Q: Which substitute offers the best tolerance specification?

A: RG2012V-182-P-T1 provides the tightest tolerance at ±0.02%, followed by RG2012N-182-W-T5 and RG2012P-182-W-T5 at ±0.05%. Selection should align with circuit accuracy requirements; tighter tolerances are necessary only for precision analog applications.

Q: Is AEC-Q200 qualification required for all applications?

A: AEC-Q200 qualification is mandatory for automotive and high-reliability applications. For consumer or industrial applications without automotive requirements, non-qualified alternatives such as RT0805CRD071K8L remain functionally compatible. Verify application specifications before selecting non-qualified parts.

Q: What is the significance of the T5 and T1 packaging designations?

A: T5 and T1 designations indicate different tape reel specifications for automated assembly. T5 and T1 are both standard Tape & Reel formats compatible with standard pick-and-place equipment. Selection between them depends on existing assembly line configuration; both formats are interchangeable from an electrical and mechanical standpoint.

Q: Can Panasonic ERA-6AEB182V be mixed with Susumu parts in the same assembly?

A: Yes. ERA-6AEB182V maintains AEC-Q200 qualification, identical electrical specifications (1.8 kOhms, ±0.1%, 0.125W), and 0805 package compatibility. Cross-manufacturer mixing is acceptable provided all parts meet the circuit's tolerance and temperature coefficient requirements. Verify with quality assurance procedures if manufacturer consistency is specified.

Q: What inventory considerations apply when selecting substitutes?

A: RG2012P-182-B-T5 offers the highest inventory availability (37,554 units), ensuring supply security for high-volume production. RG2012V-182-P-T1 (1,761 units) and ERA-6AEB182V (1,684 units) support medium-volume requirements. Confirm supplier lead times and minimum order quantities for production planning.
