Frequently Asked Questions (FAQ)

Q: Can RC0805JR-076K8L replace RC2012J682CS directly in my circuit?

A: Yes. RC0805JR-076K8L is a direct equivalent with identical electrical specifications (6.8 kΩ, ±5% tolerance, 0.125W, ±100 ppm/°C temperature coefficient, -55°C to 155°C operating range). Both parts use 0805 package format with 2 terminations. The only differences are packaging format (Cut Tape & Digi-Reel versus Tape & Reel) and maximum seated height (0.60mm versus 0.65mm), neither of which affects circuit function. Direct substitution is valid.

Q: What is the difference between the main part and upgrade parts with ±1% tolerance?

A: Upgrade parts (AC0805FR-076K8L, CR0805-FX-6801ELF, CRG0805F6K8, ERJ-6ENF6801V, KTR10EZPF6801, RC0805FR-076K8L, RMCF0805FT6K80, CRCW08056K80FKEA) provide tighter tolerance specification (±1% versus ±5%). All other electrical parameters remain identical: 6.8 kΩ resistance, 0.125W power rating, ±100 ppm/°C temperature coefficient, -55°C to 155°C operating range. Upgrade parts are functionally superior for applications requiring more precise resistance values. All maintain ROHS3 compliance and MSL 1 rating.

Q: Are all substitute parts compatible with 0805 package footprints?

A: Yes. All listed substitute parts use 0805 (2012 Metric) package format with identical footprint dimensions (0.079" L × 0.049" W / 2.00mm × 1.25mm). Maximum seated height varies between 0.50mm and 0.70mm across all parts, which is within standard PCB assembly tolerances and does not affect footprint compatibility. All parts have 2 terminations matching the main part.

Q: Which substitute parts are suitable for automotive applications?

A: Parts with Automotive AEC-Q200 certification are: AC0805FR-076K8L (YAGEO), ERJ-6ENF6801V (Panasonic), KTR10EZPF6801 (Rohm Semiconductor), RMCF0805FT6K80 (Stackpole Electronics), AC0805JR-076K8L (YAGEO), and CRCW08056K80FKEA (Vishay Dale). KTR10EZPF6801 additionally includes High Voltage features. These parts meet automotive reliability and qualification standards.

Q: Can I use parts with ±1% tolerance in place of ±5% tolerance specification?

A: Yes. Tighter tolerance (±1%) is functionally superior and compatible with circuits designed for ±5% tolerance. The actual resistance value will be closer to the nominal 6.8 kΩ specification. This substitution is valid for all applications where the original ±5% tolerance was acceptable.

Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel packaging?

A: Both packaging formats contain identical electronic components. Tape & Reel (TR) is continuous reel packaging for automated assembly lines. Cut Tape (CT) & Digi-Reel® is pre-cut tape format for manual or semi-automated assembly. Packaging format does not affect electrical function or component performance. Selection depends on assembly process requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity level, matching the main part RC2012J682CS. All parts are suitable for applications requiring RoHS compliance.

Q: What is the temperature coefficient specification and why does it matter?

A: All parts, including the main part and all substitutes, have ±100 ppm/°C temperature coefficient. This specification indicates the resistance value will change by approximately ±100 parts per million for each degree Celsius change in operating temperature. This parameter is identical across all parts and does not differentiate substitution eligibility.

Q: Can I mix different manufacturers' parts in the same circuit board?

A: Yes. All substitute parts meet identical electrical specifications (6.8 kΩ, tolerance, power rating, temperature coefficient, operating range) and mechanical compatibility (0805 package, 2 terminations). Mixing manufacturers is acceptable from an engineering standpoint. Procurement and supply chain considerations may influence final selection.
