Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RMC1/10K2940FTP is determined by strict equivalence across the following critical parameters:

Electrical Specifications:

• Resistance value: 294 Ohms (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 & Package Specifications:

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

Compliance & Environmental:

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

All identified substitute parts meet these criteria. Additional features such as Automotive AEC-Q200 certification or moisture-resistant construction represent enhanced specifications that do not preclude substitution but indicate expanded application suitability.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Status, Recommended for New Designs):

1. ERJ-6ENF2940V (Panasonic Electronic Components) — Active product with Automotive AEC-Q200 certification. Suitable for applications requiring automotive-grade reliability. Height specification (0.70mm) is within acceptable tolerance for 0805 package.

2. KTR10EZPF2940 (Rohm Semiconductor) — Active product with Automotive AEC-Q200 and High Voltage features. Identical height to main part (0.65mm). Appropriate for high-voltage circuit applications.

3. RC0805FR-07294RL (YAGEO) — Active product with moisture-resistant construction. Lowest height specification (0.60mm) among all substitutes. Suitable for moisture-sensitive environments.

4. RMCF0805FT294R (Stackpole Electronics Inc) — Active product with Automotive AEC-Q200 certification. Identical height to main part (0.65mm). Recommended for automotive applications.

Secondary Substitute (Discontinued Status):

5. MCR10ERTF2940 (Rohm Semiconductor) — Discontinued at DiGi Electronics. Electrically and mechanically equivalent but not recommended for new designs due to product status discontinuation. Suitable only for legacy system maintenance or repair applications where existing inventory exists.

All substitute parts maintain identical electrical specifications (294 Ω, ±1%, 0.125W, ±100ppm/°C, -55°C ~ 155°C) and package compatibility (0805 Thick Film, 2 terminations, MSL 1). Selection among active substitutes should be based on application requirements: automotive certification, high-voltage capability, or moisture resistance.

Frequently Asked Questions (FAQ)

Q1: Can ERJ-6ENF2940V replace RMC1/10K2940FTP directly on a PCB?

A: Yes. ERJ-6ENF2940V is electrically and mechanically equivalent. Both components have identical resistance (294 Ω), tolerance (±1%), power rating (0.125W), temperature coefficient (±100ppm/°C), operating range (-55°C ~ 155°C), and 0805 package footprint. The height difference (0.70mm vs 0.65mm) is within standard 0805 package tolerance and does not affect PCB assembly compatibility.

Q2: What is the difference between automotive AEC-Q200 rated parts and standard parts?

A: Automotive AEC-Q200 certification indicates the component meets automotive industry reliability and quality standards. Parts ERJ-6ENF2940V, KTR10EZPF2940, and RMCF0805FT294R carry this certification. For non-automotive applications, standard parts (RMC1/10K2940FTP, MCR10ERTF2940) are functionally equivalent. Selection depends on application environment and quality requirements.

Q3: Why is MCR10ERTF2940 marked as discontinued?

A: MCR10ERTF2940 is discontinued at DiGi Electronics, indicating reduced availability through primary distribution channels. However, it remains electrically and mechanically equivalent to the main part. This part should be used only for legacy system repairs or when existing inventory is available. For new designs, select from active-status alternatives.

Q4: Does the height difference between substitute parts affect circuit performance?

A: No. All substitute parts maintain 0805 (2012 Metric) package specification with height variations (0.60mm to 0.70mm) within standard package tolerance. These minor height differences do not affect electrical performance, PCB assembly, or circuit functionality. Selection based on height should consider only mechanical clearance constraints in specific board layouts.

Q5: Are all substitute parts RoHS3 compliant?

A: All substitute parts listed carry RoHS3 compliance status. The main part (RMC1/10K2940FTP) does not specify RoHS status in provided data. For applications requiring RoHS compliance certification, substitute parts ERJ-6ENF2940V, KTR10EZPF2940, MCR10ERTF2940, RC0805FR-07294RL, and RMCF0805FT294R are all suitable.

Q6: What does "Moisture Resistant" feature on RC0805FR-07294RL indicate?

A: Moisture-resistant construction provides enhanced protection against moisture ingress and corrosion in humid or high-moisture environments. All parts listed maintain MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. The moisture-resistant feature on RC0805FR-07294RL represents an additional protective characteristic suitable for applications in harsh environmental conditions.

Q7: Can KTR10EZPF2940 be used in high-voltage applications where RMC1/10K2940FTP cannot?

A: KTR10EZPF2940 is specified with "High Voltage" feature, indicating enhanced voltage rating capability. However, the provided data does not specify maximum voltage ratings for either part. Both maintain identical electrical specifications (294 Ω, ±1%, 0.125W). For high-voltage applications, consult detailed datasheets for voltage derating curves and maximum working voltage specifications.

Q8: Is packaging format (Tape & Reel vs Cut Tape) a substitution factor?

A: Packaging format affects supply and handling but does not impact electrical or mechanical compatibility. RMC1/10K2940FTP and most substitutes use Tape & Reel (TR) packaging. MCR10ERTF2940 uses Cut Tape (CT) & Digi-Reel® packaging. Both formats contain identical components; selection depends on manufacturing process requirements and inventory management practices.
