Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F68R1CS is determined by strict equivalence across the following parameters:

Critical Matching Parameters:

• Resistance value: 68.1 Ohms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Package format: 1206 (3216 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Termination count: 2
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

All identified substitute parts meet these electrical and mechanical specifications. Variations in physical dimensions (length, width, height) within standard 1206 package tolerances do not affect functional interchangeability. Environmental feature differences (anti-sulfur vs. moisture-resistant vs. automotive AEC-Q200 qualification) represent enhanced capabilities and do not prevent substitution.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (Active Status): The CR1206-FX-68R1ELF (Bourns Inc.), CRCW120668R1FKEA (Vishay Dale), and RC1206FR-0768R1L (YAGEO) are all classified as Active product status and represent current manufacturing lines suitable for new designs and ongoing production applications.

Secondary Selection (Legacy Status): The ERJ-8ENF68R1V (Panasonic Electronic Components) carries a "Not For New Designs" product status designation. This part remains functionally equivalent and electrically interchangeable but is intended for replacement or maintenance of existing assemblies only. Use of this part number in new design initiatives is not recommended.

Compliance Considerations: All substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity ratings, ensuring compatibility with standard PCB assembly and storage protocols. The CRCW120668R1FKEA and ERJ-8ENF68R1V include automotive AEC-Q200 qualification, providing enhanced reliability documentation for automotive and harsh-environment applications where such certification is specified.

Frequently Asked Questions (FAQ)

Q: Can I substitute the RCS3216F68R1CS with any of the listed equivalent parts?

A: Yes. All listed parts meet the critical electrical and mechanical specifications: 68.1 Ohms ±1%, 0.25W power rating, 1206 package format, thick film composition, ±100ppm/°C temperature coefficient, and -55°C to 155°C operating range. Physical dimension variations within standard 1206 tolerances do not affect functional interchangeability.

Q: What is the difference between the substitute parts?

A: The substitute parts differ in manufacturer, packaging format (all are Tape & Reel), and environmental features. CR1206-FX-68R1ELF and RC1206FR-0768R1L feature moisture-resistant construction. CRCW120668R1FKEA and ERJ-8ENF68R1V include automotive AEC-Q200 qualification. All parts are electrically and mechanically equivalent.

Q: Should I use the ERJ-8ENF68R1V for new designs?

A: No. The ERJ-8ENF68R1V carries "Not For New Designs" product status. For new circuit designs, select from the Active status alternatives: CR1206-FX-68R1ELF, CRCW120668R1FKEA, or RC1206FR-0768R1L.

Q: Are there package format differences I should consider?

A: All parts use the 1206 (3216 Metric) package format with 2 terminations. Minor variations in physical dimensions (length 0.122" to 0.126", height 0.024" to 0.030") fall within standard 1206 package tolerances and do not affect PCB footprint compatibility or circuit performance.

Q: Do I need to verify AEC-Q200 compliance for my application?

A: AEC-Q200 qualification is present only on CRCW120668R1FKEA and ERJ-8ENF68R1V. If your application specifies automotive-grade reliability documentation, select one of these parts. For general industrial applications, all parts are equivalent.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: MSL 1 (Unlimited) indicates these components have no moisture sensitivity limitations. They can be stored indefinitely without desiccant packaging and do not require special handling or baking procedures prior to soldering, simplifying supply chain and assembly logistics.
