Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RCS2012F7681CS are qualified based on the following criteria:

Electrical Parameters (Must Match):

• Resistance value: 7.68 kOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C

Mechanical Parameters (Must Match):

• Package type: 0805 (2012 Metric)
• Number of terminations: 2
• Physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm)

Compliance Parameters (Must Match):

• RoHS3 compliance
• Moisture Sensitivity Level: 1 (Unlimited)
• Composition: Thick Film

All identified substitute parts meet these criteria and are suitable for direct replacement in applications where the RCS2012F7681CS is specified.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are Active status components with ROHS3 compliance and MSL Level 1 rating, matching the primary specification requirements of the RCS2012F7681CS.

Packaging Considerations:

The RC0805FR-077K68L from YAGEO is supplied in Cut Tape (CT) & Digi-Reel® format, differing from the standard Tape & Reel packaging of other substitutes. This packaging type is suitable for applications requiring smaller order quantities or manual assembly processes.

Automotive Applications:

The AC0805FR-077K68L (YAGEO), CRCW08057K68FKEA (Vishay Dale), ERJ-6ENF7681V (Panasonic), and RMCF0805FT7K68 (Stackpole) carry AEC-Q200 automotive qualification ratings. These parts are suitable for automotive and high-reliability applications where automotive-grade components are specified.

Height Profile Variations:

Substitute parts exhibit maximum seated heights ranging from 0.50mm to 0.70mm. The CRCW08057K68FKEA offers the lowest profile at 0.50mm, while the ERJ-6ENF7681V reaches 0.70mm. Height considerations apply to applications with restricted vertical clearance on printed circuit boards.

Frequently Asked Questions (FAQ)

Q: Can all listed substitute parts replace the RCS2012F7681CS in any application?

A: All substitute parts match the core electrical specifications (7.68 kOhms ±1%, 0.125W, ±100ppm/°C, -55°C to 155°C) and mechanical package (0805), with identical compliance ratings (ROHS3, MSL 1). Direct substitution is supported from an electrical and mechanical standpoint. Applications with specific feature requirements (such as anti-sulfur coating or automotive qualification) should reference the detailed feature set of each substitute.

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

A: Tape & Reel packaging is standard for high-volume automated assembly operations. Cut Tape & Digi-Reel packaging (RC0805FR-077K68L) is suitable for lower-volume orders and manual assembly processes. Both packaging formats contain identical components; the difference is in supply format and handling method.

Q: Are the automotive-qualified substitutes (AEC-Q200) required for non-automotive applications?

A: AEC-Q200 qualification is not required for non-automotive applications. However, automotive-qualified parts (AC0805FR-077K68L, CRCW08057K68FKEA, ERJ-6ENF7681V, RMCF0805FT7K68) meet additional reliability and testing standards and are suitable for any application. Selection should be based on application requirements and supply chain availability.

Q: Do height differences between substitute parts affect circuit board design?

A: Height variations range from 0.50mm to 0.70mm maximum seated height. These differences are within typical PCB design tolerances for 0805 components. Height becomes a consideration only in applications with restricted vertical clearance, such as low-profile assemblies or designs with component stacking constraints.

Q: What does MSL Level 1 mean for moisture sensitivity?

A: MSL (Moisture Sensitivity Level) 1 indicates unlimited shelf life without moisture control requirements. Components rated MSL 1 do not require special moisture-barrier packaging or baking procedures prior to soldering, simplifying handling and storage procedures.

Q: Are all substitute parts ROHS3 compliant?

A: Yes, all listed substitute parts carry ROHS3 compliance certification, matching the primary part specification. ROHS3 compliance ensures restriction of hazardous substances in accordance with current environmental regulations.
