Engineering Selection Recommendations

Direct Replacement (Preferred for Non-Automotive Applications): RN73C2B10K5BTD is the direct equivalent from TE Connectivity Passive Product. This part maintains identical electrical and thermal specifications while offering active product status, ensuring long-term availability and supply chain continuity.

Upgrade Selection for Automotive Applications: For applications requiring automotive qualification, Susumu RG3216V series parts provide AEC-Q200 certification with enhanced specifications. RG3216V-1052-B-T5 offers doubled power rating (0.25W) and improved temperature coefficient (±5ppm/°C) while maintaining ±0.1% tolerance. RG3216V-1052-P-T1 provides the tightest tolerance (±0.02%) for precision applications.

Upgrade Selection for Extended Temperature Range: TNPW120610K5BYEA from Vishay Dale extends the operating temperature range to -55°C ~ 175°C and provides the highest power rating (0.52W) with AEC-Q200 automotive certification and moisture-resistant construction.

Selection Criteria:

Use RN73C2B10K5BTD for direct replacement in non-automotive designs
Use Susumu RG3216V series for automotive applications requiring AEC-Q200 certification
Use TNPW120610K5BYEA for applications requiring extended temperature range or higher power dissipation capability
All substitute parts maintain 1206 package compatibility and 10.5 kOhms resistance specification

Frequently Asked Questions (FAQ)

Q: Can RN73C2B10K5BTD be used as a direct replacement for 1614707-3? A: Yes. RN73C2B10K5BTD is electrically and mechanically identical to 1614707-3, with the advantage of active product status. Both parts share the same 10.5 kOhms resistance, ±0.1% tolerance, 0.125W power rating, 1206 package, and ±10ppm/°C temperature coefficient.

Q: What is the difference between the Susumu RG3216N and RG3216V series? A: The RG3216V series features a lower temperature coefficient (±5ppm/°C) compared to RG3216N (±10ppm/°C), providing improved stability across temperature variations. Both series offer doubled power rating (0.25W) and AEC-Q200 automotive certification.

Q: Are all substitute parts compatible with the 1206 package footprint? A: Yes. All substitute parts use the 1206 (3216 Metric) package specification. Physical dimensions are compatible with standard 1206 PCB layouts, though Susumu and Vishay parts have slightly different height specifications (0.020" vs. 0.026" maximum seated height).

Q: Which substitute part offers the best tolerance specification? A: RG3216V-1052-P-T1 provides the tightest tolerance at ±0.02%, followed by RG3216N-1052-W-T1 and RG3216V-1052-W-T1 at ±0.05%. The original 1614707-3 and most direct equivalents specify ±0.1% tolerance.

Q: Do all substitute parts support the same operating temperature range? A: Most substitute parts support -55°C ~ 155°C, matching the original specification. TNPW120610K5BYEA extends this range to -55°C ~ 175°C, providing additional thermal margin for high-temperature applications.

Q: Is AEC-Q200 certification required for my application? A: AEC-Q200 certification is required for automotive applications. For non-automotive industrial or consumer applications, RN73C2B10K5BTD provides a direct equivalent without automotive certification. Susumi RG series and Vishay TNPW series include AEC-Q200 certification for automotive designs.

Q: What is the moisture sensitivity level for all parts? A: All listed parts maintain Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions and no special storage or handling requirements.
