Key Parameters

Substitute Part Grouping Explanation

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

• Resistance Value: 31.6 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power Rating: 0.25W / 1/4W (exact match required)
• Package: 1206 (3216 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature Coefficient: ±100ppm/°C (exact match required)
• Operating Temperature Range: -55°C ~ 155°C (exact match required)
• RoHS Compliance: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

All identified substitute parts meet these criteria. Variations in physical dimensions (height, length, width) within standard tolerances and differences in packaging format (Tape & Reel versus bulk) do not affect functional substitution.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (Active Status)

CR1206-FX-31R6ELF (Bourns Inc.) and RC1206FR-0731R6L (YAGEO) are recommended as primary substitutes. Both parts maintain active production status and carry ROHS3 compliance with identical electrical specifications to the RCS3216F31R6CS.

CRCW120631R6FKEA (Vishay Dale) is suitable for applications requiring automotive-grade components, as it carries AEC-Q200 certification. This part is also in active production status.

Secondary Selection (Legacy Status)

ERJ-8ENF31R6V (Panasonic Electronic Components) carries AEC-Q200 automotive certification but is designated "Not For New Designs." This part is suitable only for legacy system maintenance or replacement applications where the original specification included this component.

All substitute parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.

Frequently Asked Questions (FAQ)

Q: Can CR1206-FX-31R6ELF replace RCS3216F31R6CS in existing designs?

A: Yes. Both parts share identical electrical specifications (31.6 Ohms ±1%, 0.25W), operate across the same temperature range (-55°C ~ 155°C), and are packaged in 1206 (3216 Metric) format. Physical height variation (0.030" versus 0.026") falls within standard PCB assembly tolerances.

Q: What is the difference between moisture-resistant and anti-sulfur features?

A: The RCS3216F31R6CS includes both anti-sulfur and moisture-resistant properties. Substitute parts CR1206-FX-31R6ELF and RC1206FR-0731R6L specify moisture-resistant composition. Both feature sets provide environmental protection; anti-sulfur specifically addresses corrosion from sulfur-containing atmospheres. All parts carry MSL 1 (Unlimited) rating.

Q: Should ERJ-8ENF31R6V be used in new circuit designs?

A: No. ERJ-8ENF31R6V is designated "Not For New Designs" by Panasonic. This part is appropriate only for replacement or maintenance of existing systems that originally specified this component. For new designs, select from CR1206-FX-31R6ELF, CRCW120631R6FKEA, or RC1206FR-0731R6L.

Q: Are automotive-grade parts (AEC-Q200) interchangeable with standard industrial parts?

A: Yes, for substitution purposes. CRCW120631R6FKEA and ERJ-8ENF31R6V carry AEC-Q200 certification, indicating enhanced reliability testing and qualification. These parts meet or exceed the electrical and environmental specifications of non-automotive equivalents and are functionally interchangeable.

Q: Does packaging format (Tape & Reel versus bulk) affect substitution?

A: No. Packaging format affects procurement and handling but not electrical or mechanical function. All identified substitutes are available in Tape & Reel format, suitable for automated assembly processes.

Q: What is the significance of the 1206 (3216 Metric) package designation?

A: This dual designation indicates the package size in both imperial (1206) and metric (3216) standards. The physical dimensions are 0.126" L × 0.063" W (3.20mm × 1.60mm). All substitute parts use this identical package, ensuring PCB footprint compatibility.

Q: Can these 31.6 Ohm resistors be used interchangeably in high-frequency applications?

A: All parts share identical temperature coefficient (±100ppm/°C) and composition (thick film). Frequency performance depends on circuit design and PCB layout rather than resistor selection among these equivalents.
