RPC2010KT680R Equivalent & Substitute Parts

Part Overview

The RPC2010KT680R is a 680 Ohm ±10% thick film chip resistor rated for 0.75W power dissipation in a 2010 (5025 Metric) surface mount package. This Stackpole Electronics component is AEC-Q200 automotive qualified with pulse withstanding capability, operating across -55°C to 155°C. The part is currently active in production with 824 units in stock.

Substitute parts are identified when equivalent electrical performance can be maintained within the allowed tolerance and power rating specifications while meeting the same package and environmental requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence in the following parameters:

• Resistance value: 680 Ohms (exact match required)
• Power rating: 0.75W minimum
• Package: 2010 (5025 Metric) form factor
• Temperature range: -55°C to 155°C minimum
• Composition: Thick film construction
• Compliance: ROHS3 and REACH requirements

Tolerance variations (±10%, ±5%, ±1%) are permitted substitutions when the application circuit design allows tighter tolerance performance. Automotive AEC-Q200 certification is maintained across all qualified substitutes. Moisture Sensitivity Level 1 is consistent across all candidates.

Parameter Comparison

Engineering Selection Recommendations

RPC2010JT680R (Stackpole Electronics Inc) is the primary upgrade substitute, offering tighter ±5% tolerance while maintaining identical AEC-Q200 automotive qualification, power rating, and package specifications. This part remains in active production status with higher inventory availability (2054 units).

ERJ-12SF6800U (Panasonic Electronic Components) provides the highest tolerance precision at ±1% with AEC-Q200 certification and substantial inventory (13829 units). However, this part is designated "Not For New Designs," limiting its suitability for new development programs.

RC2010FK-07680RL (YAGEO) and RC2010JK-07680RL (YAGEO) are active production alternatives with moisture-resistant thick film construction. These parts lack explicit AEC-Q200 automotive certification in the provided specifications, which may restrict their use in automotive applications requiring this qualification.

Frequently Asked Questions (FAQ)

Q: Can RPC2010JT680R directly replace RPC2010KT680R?

A: Yes. Both parts share identical resistance (680 Ω), power rating (0.75W), package (2010), temperature range (-55°C to 155°C), and AEC-Q200 automotive qualification. The RPC2010JT680R offers improved tolerance (±5% versus ±10%), which is a performance upgrade compatible with circuits designed for the original specification.

Q: What is the difference between ±10%, ±5%, and ±1% tolerance parts?

A: Tolerance defines the maximum deviation from the nominal 680 Ω resistance value. ±10% allows 612–748 Ω, ±5% allows 646–714 Ω, and ±1% allows 673–687 Ω. Tighter tolerance parts (±5%, ±1%) are suitable for precision circuits; looser tolerance parts (±10%) are acceptable for general applications where resistance variation has minimal impact on circuit performance.

Q: Why is ERJ-12SF6800U marked "Not For New Designs"?

A: This designation indicates the part is in mature production phase with no active development. While existing inventory is available for replacement or repair applications, new product designs should specify active production alternatives such as RPC2010JT680R or RC2010JK-07680RL.

Q: Are YAGEO RC2010 series parts suitable for automotive applications?

A: RC2010FK-07680RL and RC2010JK-07680RL are moisture-resistant thick film resistors in active production. However, the provided specifications do not confirm AEC-Q200 automotive qualification for these parts. Automotive applications requiring AEC-Q200 certification should prioritize Stackpole RPC2010JT680R or Panasonic ERJ-12SF6800U.

Q: Can I mix different substitute parts in the same circuit board assembly?

A: All listed substitutes maintain identical resistance (680 Ω), power rating (0.75W), package (2010), and operating temperature range (-55°C to 155°C). Mixing parts with different tolerances (±10%, ±5%, ±1%) is permissible if circuit design tolerances accommodate the widest tolerance specification used. Verify that automotive qualification requirements are consistently met across all selected parts.
