Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RMC1/10K3091FTP is determined by the following mandatory parameters:

Electrical Parameters:

• Resistance value: 3.09 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.125W / 1/8W (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)

Mechanical Parameters:

• Package / Case: 0805 (2012 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Number of terminations: 2 (exact match required)

Environmental & Compliance Parameters:

• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)
• REACH Status: REACH Unaffected (exact match required)
• ECCN: EAR99 (exact match required)

All substitute parts listed below meet these mandatory criteria. Additional features such as automotive AEC-Q200 certification or moisture-resistant construction represent value-added characteristics that do not disqualify substitution but may be relevant for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

ERJ-6ENF3091V (Panasonic Electronic Components) and RMCF0805FT3K09 (Stackpole Electronics Inc) are recommended as primary substitutes. Both components maintain Active product status and carry ROHS3 compliance certification. ERJ-6ENF3091V includes automotive AEC-Q200 qualification, suitable for applications requiring automotive-grade reliability. RMCF0805FT3K09 similarly carries AEC-Q200 certification. RC0805FR-073K09L (YAGEO) is an Active product with moisture-resistant construction and represents an alternative with high inventory availability (59,593 pieces).

Secondary Substitute (Discontinued Status):

MCR10ERTF3091 (Rohm Semiconductor) is listed as Discontinued at DiGi Electronics. While electrically and mechanically equivalent, this part should be selected only when supply from primary substitutes is unavailable. Current inventory is 1,002 pieces.

Compliance Considerations:

All substitute parts meet REACH Unaffected and EAR99 ECCN classifications, matching the original RMC1/10K3091FTP specifications. Automotive applications requiring AEC-Q200 certification should prioritize ERJ-6ENF3091V or RMCF0805FT3K09.

Frequently Asked Questions (FAQ)

Q: Can ERJ-6ENF3091V be used as a direct replacement for RMC1/10K3091FTP?

A: Yes. ERJ-6ENF3091V meets all mandatory electrical and mechanical parameters: 3.09 kOhms ±1%, 0.125W power rating, 0805 package, thick film composition, ±100ppm/°C temperature coefficient, and -55°C ~ 155°C operating range. The maximum seated height is 0.028" (0.70mm) compared to 0.026" (0.65mm) for the original part; this 0.002" difference is within typical PCB design tolerances for 0805 components.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel® packaging?

A: Tape & Reel (TR) packaging provides continuous reel format suitable for high-volume automated assembly. Cut Tape (CT) & Digi-Reel® packaging offers smaller quantity options and alternative reel formats. Both packaging types contain identical components; selection depends on production volume and assembly equipment compatibility.

Q: Why is MCR10ERTF3091 marked as Discontinued at DiGi Electronics?

A: MCR10ERTF3091 is discontinued at DiGi Electronics as a distributor but remains electrically and mechanically equivalent to RMC1/10K3091FTP. Discontinuation status reflects distributor inventory decisions, not component obsolescence. This part should be selected only when primary substitutes are unavailable.

Q: Are all substitute parts RoHS3 compliant?

A: ERJ-6ENF3091V, MCR10ERTF3091, RC0805FR-073K09L, and RMCF0805FT3K09 are all ROHS3 compliant. The original RMC1/10K3091FTP does not specify RoHS status in the provided data.

Q: Which substitute part has the lowest profile height?

A: RC0805FR-073K09L has the lowest maximum seated height at 0.024" (0.60mm), compared to 0.026" (0.65mm) for RMC1/10K3091FTP, MCR10ERTF3091, and RMCF0805FT3K09. ERJ-6ENF3091V has the highest profile at 0.028" (0.70mm). These height variations are within standard 0805 component tolerances.

Q: Can I use RMCF0805FT3K09 in automotive applications?

A: Yes. RMCF0805FT3K09 carries AEC-Q200 automotive qualification, making it suitable for automotive applications. ERJ-6ENF3091V also carries AEC-Q200 certification. The original RMC1/10K3091FTP does not specify automotive qualification.
