Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RMC1/8K3301FTP is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 3.3 kOhms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Package: 1206 (3216 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Moisture sensitivity level: 1 (Unlimited)
• Number of terminations: 2

All identified substitute parts meet these mandatory electrical and mechanical specifications. Substitute parts may differ in manufacturer, series designation, packaging format (Tape & Reel vs. Cut Tape), product status classification, or optional certifications (such as AEC-Q200 automotive qualification), but these differences do not affect functional equivalence in applications where the base electrical parameters are the controlling requirement.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection Criteria:

All substitute parts listed are electrically and mechanically equivalent to the RMC1/8K3301FTP. Selection among these alternatives is based on the following factors:

For Active Product Status Applications: CRG1206F3K3 (TE Connectivity), KTR18EZPF3301 (Rohm), RC1206FR-073K3L (YAGEO), and RMCF1206FT3K30 (Stackpole) all maintain Active product status, indicating ongoing manufacturer support and continued availability.

For RoHS3 Compliance Requirements: All substitute parts except the main part carry explicit ROHS3 Compliant certification. If regulatory compliance documentation is required, any of the five substitute parts satisfy this requirement.

For Automotive Applications (AEC-Q200): ERJ-8ENF3301V (Panasonic), KTR18EZPF3301 (Rohm), and RMCF1206FT3K30 (Stackpole) carry AEC-Q200 automotive qualification. These parts are suitable for automotive circuit designs where this certification is specified.

For High-Volume Availability: RC1206FR-073K3L (YAGEO) maintains the highest inventory level at 500,100 pieces, followed by RMCF1206FT3K30 (Stackpole) at 130,438 pieces and CRG1206F3K3 (TE Connectivity) at 66,349 pieces. These options provide superior supply chain security for high-volume production requirements.

For Moisture-Resistant Applications: RC1206FR-073K3L (YAGEO) is explicitly specified as Moisture Resistant, providing enhanced performance in humid or moisture-prone environments.

Avoid for New Designs: ERJ-8ENF3301V (Panasonic) carries a "Not For New Designs" product status designation. This part remains available for replacement and repair of existing equipment but should not be selected for new product development.

Frequently Asked Questions (FAQ)

Q: Can I substitute any of these parts directly into a circuit designed for the RMC1/8K3301FTP?

A: Yes. All listed substitute parts meet the mandatory electrical and mechanical specifications: 3.3 kOhms ±1% tolerance, 0.25W power rating, 1206 package, thick film composition, ±100ppm/°C temperature coefficient, and -55°C to 155°C operating range. Direct substitution is electrically valid without circuit modification.

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

A: Tape & Reel packaging is supplied on continuous carrier tape wound on reels, suitable for automated pick-and-place assembly. Cut Tape packaging is supplied in shorter tape segments, typically for lower-volume or manual assembly operations. The RMC1/8K3301FTP uses Tape & Reel; RC1206FR-073K3L uses Cut Tape & Digi-Reel. Both formats contain identical components; packaging format selection depends on assembly process requirements.

Q: Why does ERJ-8ENF3301V show "Not For New Designs" status?

A: This designation indicates the manufacturer (Panasonic) has discontinued active development and promotion of this part number. While the part remains available for existing equipment maintenance and repair, it should not be selected for new product designs. Alternative parts with Active status are preferred for new applications.

Q: Do I need AEC-Q200 certification for my application?

A: AEC-Q200 certification is required only for automotive applications subject to automotive industry standards. If your circuit is not used in automotive systems, non-certified parts (CRG1206F3K3, RC1206FR-073K3L) are functionally equivalent. If automotive qualification is required, select from ERJ-8ENF3301V, KTR18EZPF3301, or RMCF1206FT3K30.

Q: What does MSL 1 (Unlimited) mean?

A: Moisture Sensitivity Level 1 indicates the component has unlimited shelf life and requires no special moisture-control storage conditions. All listed parts carry this rating, meaning they can be stored and handled under standard industrial conditions without moisture-related degradation.

Q: Which substitute offers the best supply chain availability?

A: RC1206FR-073K3L (YAGEO) provides the highest current inventory at 500,100 pieces. For high-volume production or long-term supply security, this part offers the strongest availability position.

Q: Are there dimensional differences between these parts?

A: Minor dimensional variations exist within the 1206 package specification. Length ranges from 0.122" to 0.126", width from 0.061" to 0.063", and height from 0.025" to 0.028". These variations remain within standard 1206 package tolerances and do not affect PCB layout or assembly compatibility.

Q: What is the significance of the temperature coefficient ±100ppm/°C?

A: Temperature coefficient specifies how much the resistance value changes per degree Celsius of temperature change. All listed parts share ±100ppm/°C, meaning resistance stability across the -55°C to 155°C operating range is identical. This parameter is critical for precision analog circuits and temperature-sensitive applications.
