Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RMC1/10K3240FTP are qualified based on the following criteria:

Electrical Parameters (Must Match):

• Resistance value: 324 Ohms
• 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)

Material & Composition (Must Match):

• Thick film construction

Environmental & Compliance (Acceptable Variations):

• Moisture Sensitivity Level: 1 (Unlimited) - all substitutes meet this requirement
• RoHS and REACH compliance status may vary but do not affect electrical or mechanical compatibility

Substitutes may include additional features (such as Automotive AEC-Q200 certification or moisture resistance) or different packaging formats (Cut Tape vs. Tape & Reel) without affecting core substitution eligibility. Product status variations (Active vs. Discontinued) are noted for procurement planning purposes only.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Status, Tape & Reel Packaging):

ERJ-6ENF3240V (Panasonic) and RMCF0805FT324R (Stackpole Electronics Inc) are recommended as primary substitutes. Both maintain Active product status, are supplied in Tape & Reel format compatible with automated assembly, and meet all electrical and mechanical specifications. ERJ-6ENF3240V includes Automotive AEC-Q200 certification. RMCF0805FT324R also carries AEC-Q200 rating. Both are RoHS3 compliant.

Secondary Substitutes (Active Status, Alternative Packaging):

RC0805FR-07324RL (YAGEO) is Active with the lowest seated height (0.024" / 0.60mm) and includes moisture-resistant features. This part is supplied in Tape & Reel format with the highest inventory availability (191,628 pieces). KTR10EZPF3240 (Rohm Semiconductor) is Active with high-voltage capability and AEC-Q200 certification, supplied in Tape & Reel format.

Discontinued Parts (Not Recommended for New Designs):

MCR10ERTF3240 (Rohm Semiconductor) is marked as Discontinued at DiGi Electronics and supplied in Cut Tape & Digi-Reel format. This part should not be selected for new production designs due to discontinued status, though it remains electrically and mechanically compatible.

Compliance Considerations:

All substitute parts are REACH Unaffected and classified as EAR99 for export control purposes. RoHS3 compliance is confirmed for all Active parts. Moisture Sensitivity Level 1 (Unlimited) is maintained across all substitutes.

Frequently Asked Questions (FAQ)

Q: Can ERJ-6ENF3240V replace RMC1/10K3240FTP directly on the circuit board?

A: Yes. ERJ-6ENF3240V meets all electrical specifications (324 Ω ±1%, 0.125W, ±100ppm/°C, -55°C to 155°C) and mechanical requirements (0805 package, 2 terminations). The maximum seated height difference is 0.002" (0.70mm vs. 0.65mm), which is within standard PCB assembly tolerances for 0805 components.

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

A: Tape & Reel packaging is supplied on continuous carrier tape wound on reels, suitable for high-speed automated pick-and-place assembly. Cut Tape & Digi-Reel packaging is pre-cut into smaller quantities on tape strips, typically used for lower-volume or manual assembly operations. Both formats contain identical components; packaging format selection depends on assembly process requirements.

Q: Does Automotive AEC-Q200 certification affect substitution compatibility?

A: No. AEC-Q200 certification indicates the part meets automotive industry reliability and qualification standards. Parts with AEC-Q200 (ERJ-6ENF3240V, KTR10EZPF3240, RMCF0805FT324R) are fully compatible with non-automotive applications and provide additional qualification assurance. Parts without AEC-Q200 remain electrically and mechanically equivalent.

Q: Are there height restrictions for 0805 resistor substitution?

A: Standard PCB assembly processes accommodate 0805 component height variations within the range provided (0.024" to 0.028" / 0.60mm to 0.70mm). All substitute parts fall within this range. Specific height constraints should be verified against PCB design specifications if space limitations exist.

Q: What does ±100ppm/°C temperature coefficient mean for circuit performance?

A: Temperature coefficient specifies resistance change per degree Celsius. At ±100ppm/°C, a 324 Ω resistor changes by approximately 0.0324 Ω per °C. Across the full operating range (-55°C to 155°C, 210°C span), maximum resistance drift is approximately ±6.8 Ω. All substitute parts maintain identical temperature coefficient specifications.

Q: Is inventory availability a factor in substitute selection?

A: Inventory levels are provided for procurement planning. RC0805FR-07324RL (YAGEO) has the highest availability at 191,628 pieces. However, inventory quantities fluctuate and should not be the primary selection criterion. Electrical compatibility, product status, and compliance requirements take precedence.

Q: Can I use RMCF0805FT324R if my design requires moisture-resistant components?

A: RMCF0805FT324R does not explicitly list moisture-resistant features. RC0805FR-07324RL (YAGEO) is specified as moisture-resistant. If moisture resistance is a design requirement, RC0805FR-07324RL is the appropriate selection among the listed substitutes.
