Key Parameters

Substitute Part Grouping Explanation

Substitution of the RC3216F1R8CS is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Resistance value (1.8 Ohms), tolerance (±1%), and power rating (0.25W) must be identical across all substitute parts.

Mechanical Parameters: Package type (1206 / 3216 Metric) and number of terminations (2) must match exactly to ensure PCB footprint compatibility and assembly process compatibility.

Environmental & Compliance Parameters: All substitute parts must maintain ROHS3 compliance, MSL Level 1 rating, and operating temperature range of -55°C ~ 155°C to ensure equivalent reliability and regulatory acceptance.

Composition: Thick film construction is maintained across all substitutes to preserve electrical performance characteristics.

The three identified substitute parts (ERJ-8RQF1R8V, RC1206FR-071R8L, RMCF1206FT1R80) meet all mandatory electrical and mechanical equivalence criteria. Two substitutes include automotive AEC-Q200 certification, which represents an enhancement rather than a deviation from the base specification.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are functionally equivalent to the RC3216F1R8CS based on electrical and mechanical parameters. Selection among substitutes should be based on the following criteria:

For General-Purpose Applications: RC1206FR-071R8L (YAGEO) offers the highest inventory availability (1,513,071 pieces) and maintains identical moisture-resistant thick film construction with ROHS3 compliance.

For Automotive Applications: ERJ-8RQF1R8V (Panasonic) and RMCF1206FT1R80 (Stackpole) both carry AEC-Q200 automotive qualification. ERJ-8RQF1R8V includes current sense capability, while RMCF1206FT1R80 provides 36,546 pieces in stock.

For Temperature-Sensitive Applications: All substitutes maintain the required -55°C ~ 155°C operating range. ERJ-8RQF1R8V, RC1206FR-071R8L, and RMCF1206FT1R80 feature ±200ppm/°C temperature coefficient, which is superior to the original RC3216F1R8CS specification of ±300ppm/°C.

For Supply Chain Continuity: YAGEO RC1206FR-071R8L demonstrates the strongest inventory position and represents a direct functional equivalent without additional certifications.

Frequently Asked Questions (FAQ)

Q: Can ERJ-8RQF1R8V replace RC3216F1R8CS in non-automotive applications?

A: Yes. ERJ-8RQF1R8V meets all electrical and mechanical equivalence criteria. The AEC-Q200 automotive certification is an additional qualification that does not restrict use in general-purpose applications. The component is electrically and mechanically identical for PCB assembly and circuit operation.

Q: What is the difference between the temperature coefficients listed for these parts?

A: RC3216F1R8CS specifies ±300ppm/°C, while the three substitutes specify ±200ppm/°C. A lower temperature coefficient indicates superior stability across temperature variations. The substitutes provide enhanced performance in this parameter while maintaining full compatibility.

Q: Are all substitute parts available in Tape & Reel packaging?

A: Yes. ERJ-8RQF1R8V, RC1206FR-071R8L, and RMCF1206FT1R80 are all supplied in Tape & Reel (TR) packaging, which is standard for automated PCB assembly processes.

Q: Do the physical dimensions vary between the main part and substitutes?

A: Minor variations exist within acceptable tolerances. RC3216F1R8CS and RMCF1206FT1R80 measure 0.126" L × 0.063" W (3.20mm × 1.60mm), while RC1206FR-071R8L measures 0.122" L × 0.063" W (3.10mm × 1.60mm). All fit the 1206 (3216 Metric) footprint. Height-seated maximum values range from 0.026" to 0.028", which is within standard PCB assembly clearance specifications.

Q: Which substitute part has the best inventory availability?

A: RC1206FR-071R8L (YAGEO) has 1,513,071 pieces in stock, significantly exceeding the availability of other options. ERJ-8RQF1R8V (Panasonic) has 15,516 pieces, and RMCF1206FT1R80 (Stackpole) has 36,546 pieces.

Q: Are all parts REACH compliant?

A: Yes. RC3216F1R8CS, ERJ-8RQF1R8V, RC1206FR-071R8L, and RMCF1206FT1R80 are all listed as REACH Unaffected, indicating compliance with REACH regulations.
