Frequently Asked Questions (FAQ)

Q: Can the RR1220P-1623-D-M directly replace the 1614959-2?

A: Yes. The RR1220P-1623-D-M provides identical electrical specifications: 162 kOhms ±0.5% at 0.1W in 0805 package. The operating temperature range differs slightly (-55°C to 125°C versus -55°C to 155°C), which is acceptable for most applications. This part is active product status.

Q: What is the difference between direct equivalents and upgrade parts?

A: Direct equivalents match the original 1614959-2 specifications exactly (±0.5% tolerance, 0.1W power). Upgrade parts offer enhanced specifications: tighter tolerance (±0.1% or ±0.05%), higher power rating (0.125W), and active product status. Upgrades are backward compatible and provide improved performance margins.

Q: Are all substitute parts compatible with the 0805 package footprint?

A: Yes. All listed substitute parts use the 0805 (2012 Metric) package with identical footprint dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm). Physical board layout compatibility is maintained across all substitutes.

Q: Which substitute part is recommended for automotive applications?

A: ERA-6AEB1623V (Panasonic), RG2012N-1623-B-T5, RG2012N-1623-D-T5, RG2012N-1623-W-T1, RG2012P-1623-B-T5, RG2012P-1623-D-T5, and RG2012P-1623-W-T5 (Susumu) all carry Automotive AEC-Q200 certification. Selection depends on tolerance and temperature coefficient requirements.

Q: What is the difference between RG2012N and RG2012P series?

A: Both series offer anti-sulfur and Automotive AEC-Q200 features in 0805 package. The RG2012N series features ±10ppm/°C temperature coefficient. The RG2012P series features ±25ppm/°C temperature coefficient. Both are available in ±0.05%, ±0.1%, and ±0.5% tolerance options.

Q: Can I use a higher tolerance part (±0.5%) in place of the original ±0.5% specification?

A: Yes. Parts with equal or tighter tolerance specifications are compatible. RG2012N-1623-D-T5 and RG2012P-1623-D-T5 maintain ±0.5% tolerance while offering higher power rating and active product status.

Q: What does "anti-sulfur" protection mean?

A: Anti-sulfur protection prevents corrosion and degradation caused by sulfur-containing environments. This feature is present in MCU08050D1623BP100 and all Susumu RG series parts, providing enhanced reliability in harsh industrial and automotive environments.

Q: Are all substitute parts RoHS3 compliant?

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

Q: What is the Moisture Sensitivity Level (MSL) for all parts?

A: All parts, including the original 1614959-2 and all substitutes, have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage and handling.
