Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC3216F7681CS is determined by strict equivalence across the following parameters:

Mandatory Matching Parameters:

• Resistance value: 7.68 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.25W minimum (equal or higher acceptable)
• Package: 1206 (3216 Metric) form factor (exact match required)
• Composition: Thick film construction
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C minimum
• Moisture sensitivity: MSL 1 or better
• RoHS compliance: ROHS3 or equivalent

Acceptable Variations:

• Manufacturer identity (different suppliers permitted)
• Packaging format (Tape & Reel acceptable for bulk applications)
• Physical dimensions within tolerance (length 3.10mm to 3.20mm, width 1.60mm, height 0.60mm to 0.70mm)
• Product status (Active preferred; Not For New Designs acceptable for legacy applications)
• Additional certifications (AEC-Q200 automotive qualification adds capability without reducing compatibility)

All three substitute parts meet these criteria and are electrically and mechanically interchangeable with the main part.

Parameter Comparison

Engineering Selection Recommendations

RC1206FR-077K68L (YAGEO) is the primary direct substitute. This part maintains identical electrical specifications and is in Active product status. YAGEO's RC series offers the highest inventory availability (158,341 pieces) and is suitable for standard industrial applications requiring no automotive qualification.

CRCW12067K68FKEA (Vishay Dale) is recommended for applications requiring automotive-grade components. This part carries AEC-Q200 certification, indicating qualification for automotive environments. The CRCW series is Active and provides enhanced reliability documentation for mission-critical applications. Physical dimensions match the main part exactly.

ERJ-8ENF7681V (Panasonic) provides an alternative with AEC-Q200 automotive qualification. However, this part is marked "Not For New Designs," indicating Panasonic has discontinued active development. This part is suitable only for legacy system maintenance or replacement in existing designs where the original specification included this component. Use only when supply of active alternatives is constrained.

All three substitutes are electrically and mechanically equivalent to RC3216F7681CS and require no circuit redesign or PCB layout modification.

Frequently Asked Questions (FAQ)

Q: Can I substitute RC1206FR-077K68L for RC3216F7681CS without circuit modification?

A: Yes. Both parts are 7.68 kOhms ±1% 0.25W thick film resistors in 1206 package with identical electrical characteristics and operating ranges. No circuit redesign is required. Physical dimensions are within tolerance (YAGEO: 3.10mm length vs. Samsung: 3.20mm length), and both mount on standard 1206 footprints.

Q: What is the difference between the Samsung and YAGEO parts?

A: The RC3216F7681CS (Samsung) and RC1206FR-077K68L (YAGEO) are functionally identical. Differences are limited to manufacturer identity, packaging format (bulk vs. Tape & Reel), and inventory availability. Both are Active products with identical electrical specifications.

Q: Should I use the Vishay Dale CRCW12067K68FKEA or Panasonic ERJ-8ENF7681V?

A: For new designs, use CRCW12067K68FKEA (Vishay Dale). This part is Active and carries AEC-Q200 automotive certification. The Panasonic ERJ-8ENF7681V is marked "Not For New Designs" and should be used only for replacement in existing systems that originally specified this component.

Q: Are the physical dimensions compatible with my PCB?

A: All four parts use the 1206 (3216 Metric) package. Physical dimensions vary slightly: Samsung and Vishay are 3.20mm length; YAGEO is 3.10mm length; Panasonic is 3.20mm length. All fit standard 1206 footprints. Height variations (0.60mm to 0.70mm) are within PCB assembly tolerances.

Q: Do I need to update my bill of materials if I switch suppliers?

A: This depends on your procurement and quality procedures. If your design specifies "7.68 kOhms ±1% 1/4W 1206 thick film resistor," any of these four parts satisfy the requirement. If your BOM specifies a single manufacturer part number, update it to reflect the selected substitute and notify your quality and manufacturing teams.

Q: What is the difference between "Active" and "Not For New Designs" status?

A: "Active" indicates the manufacturer continues production and supports the part for new applications. "Not For New Designs" indicates the manufacturer has discontinued active development but may continue limited production for legacy support. Use Active parts for new designs; use "Not For New Designs" parts only for replacement in existing systems.

Q: Are all these parts RoHS compliant?

A: Yes. All four parts are ROHS3 compliant and REACH unaffected. They are suitable for applications requiring environmental compliance in EU and equivalent markets.

Q: What does MSL 1 (Unlimited) mean?

A: MSL (Moisture Sensitivity Level) 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. All four parts carry this rating, eliminating moisture-related procurement constraints.
