• RG2012N-3920-B-T5, RG2012V-3920-B-T5 (Susumu): Increase power rating to 0.125W with Anti-Sulfur construction and Automotive AEC-Q200 qualification. RG2012V-3920-B-T5 offers improved temperature coefficient (±5ppm/°C). All ROHS3 compliant, active status.

• RG2012N-3920-W-T1, RG2012N-3920-W-T5 (Susumu): Provide tighter tolerance (±0.05%), increased power rating (0.125W), Anti-Sulfur construction, and Automotive AEC-Q200 qualification. ROHS3 compliant, active status.

Selection Criteria:

For direct replacement in non-automotive applications, select from TE Connectivity RN73C2A series or YAGEO RT0805BRB07392RL based on packaging requirements and inventory availability.

For automotive or high-reliability applications, select from Susumu RG series parts, which provide AEC-Q200 qualification and Anti-Sulfur features.

For applications requiring tighter tolerance control, select RG2012N-3920-W-T1 or RG2012N-3920-W-T5 (±0.05% tolerance).

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and -55°C to 155°C operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can RN73R2ATTD3920B10 be used as a direct replacement for RN732ATTD3920B10?

A: Yes. RN73R2ATTD3920B10 provides direct electrical equivalence with identical resistance (392 Ω), tolerance (±0.1%), temperature coefficient (±10ppm/°C), and operating temperature range (-55°C to 155°C). The increased power rating (0.125W vs. 0.1W) provides additional design margin. Both components use 0805 (2012 Metric) package with thin film construction and MSL 1 rating.

Q: What is the difference between TE Connectivity RN73C2A392RBTD and RN73C2A392RBTDF?

A: Both parts are electrically identical with 392 Ω resistance, ±0.1% tolerance, 0.1W power rating, and ±10ppm/°C temperature coefficient. The primary difference is packaging format: RN73C2A392RBTD is supplied in Tape & Reel (TR) format, while RN73C2A392RBTDF is also Tape & Reel but with higher inventory availability (3657 pcs vs. 996 pcs). Both are ROHS3 compliant and active products.

Q: Are Susumu RG2012 series parts compatible with the original 0805 package footprint?

A: Yes. All Susumu RG2012 series parts (RG2012N-3920-B-T5, RG2012N-3920-W-T1, RG2012N-3920-W-T5, RG2012V-3920-B-T5) use 0805 (2012 Metric) package with identical dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm). Physical footprint compatibility is maintained. These parts offer enhanced features including Anti-Sulfur construction and Automotive AEC-Q200 qualification.

Q: What does Automotive AEC-Q200 qualification mean for component selection?

A: AEC-Q200 is an automotive industry standard qualification for passive components. Parts bearing this rating (RN73R2ATTD3920B10, RG2012N-3920-B-T5, RG2012N-3920-W-T1, RG2012N-3920-W-T5, RG2012V-3920-B-T5) have undergone rigorous testing for automotive applications including temperature cycling, humidity resistance, and reliability under vehicle operating conditions. These parts are suitable for automotive and high-reliability industrial applications.

Q: Can I use a ±0.05% tolerance part (RG2012N-3920-W-T1 or RG2012N-3920-W-T5) in place of the ±0.1% original?

A: Yes. Tighter tolerance (±0.05%) is a specification upgrade that provides improved accuracy. Any circuit designed for ±0.1% tolerance will function correctly with ±0.05% components. This substitution is appropriate for precision analog circuits or applications requiring tighter component matching.

Q: What is the significance of the temperature coefficient difference between RG2012V-3920-B-T5 (±5ppm/°C) and the original (±10ppm/°C)?

A: Lower temperature coefficient indicates reduced resistance variation across the operating temperature range. RG2012V-3920-B-T5 with ±5ppm/°C provides superior temperature stability compared to the original ±10ppm/°C specification. This upgrade is beneficial for precision measurement circuits, oscillators, and temperature-sensitive analog applications.

Q: Are all substitute parts ROHS3 compliant?

A: All listed substitute parts are ROHS3 compliant except RN73C2A392RBTDG, which is listed as RoHS Compliant (without specific version designation). ROHS3 compliance indicates compliance with Restriction of Hazardous Substances Directive including exemptions for lead in high-melting-point solders and other specified applications.

Q: What packaging formats are available for substitute parts?

A: Substitute parts are available in two packaging formats: Tape & Reel (TR) for automated assembly and Strip for manual or semi-automated handling. RN73C2A392RBTG is supplied in Strip format; all other substitute parts are Tape & Reel. Format selection depends on assembly process requirements and production volume.

Q: Is inventory availability a factor in component selection?

A: Inventory availability should be considered for supply chain planning. RN73C2A392RBTDF offers the highest availability (3657 pcs), followed by RG2012V-3920-B-T5 (1077 pcs) and RG2012N-3920-B-T5 (1044 pcs). For applications requiring immediate availability, these parts are recommended. Lower inventory parts (RT0805BRB07392RL at 728 pcs, RG2012N-3920-W-T1 at 762 pcs) may require longer lead times.
