Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RMC1/10K43R2FTP is determined by strict equivalence across the following parameters:

Critical Matching Parameters:

• Resistance value: 43.2 Ohms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Package: 0805 (2012 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Termination count: 2
• Moisture sensitivity level: 1 (Unlimited)

All identified substitute parts meet these electrical and mechanical requirements. Dimensional variations within the 0805 package specification (height differences of ±0.004" maximum) do not affect functional interchangeability in standard PCB assembly processes.

Parameter Comparison

Engineering Selection Recommendations

All four parts listed—RMC1/10K43R2FTP, ERJ-6ENF43R2V, RC0805FR-0743R2L, and RMCF0805FT43R2—are functionally equivalent for direct substitution based on electrical and mechanical parameters.

Compliance and Certification Status:

ERJ-6ENF43R2V (Panasonic) and RMCF0805FT43R2 (Stackpole) carry AEC-Q200 automotive qualification. RC0805FR-0743R2L (YAGEO) features moisture-resistant construction. All parts are ROHS3 compliant and REACH unaffected.

Selection between these parts should be based on:

• Availability requirements (inventory levels vary: Panasonic 119,336 pcs, YAGEO 110,297 pcs, Stackpole 2,244 pcs, Kamaya 631 pcs)
• Automotive application requirements (AEC-Q200 certification if needed)
• Environmental exposure conditions (moisture resistance consideration)
• Supply chain and procurement preferences

Frequently Asked Questions (FAQ)

Q: Can ERJ-6ENF43R2V replace RMC1/10K43R2FTP directly on the PCB?

A: Yes. Both parts share identical electrical specifications (43.2 Ohms ±1%, 0.125W), temperature coefficient (±100ppm/°C), operating range (-55°C to 155°C), and 0805 package dimensions. Height variation (0.028" vs 0.026") is within standard PCB assembly tolerances.

Q: What is the difference between RC0805FR-0743R2L and the other substitutes?

A: RC0805FR-0743R2L incorporates moisture-resistant construction and has the lowest seated height (0.024"). Electrical performance is identical to all other parts. This variant is suitable for applications with elevated humidity exposure.

Q: Are RMCF0805FT43R2 and ERJ-6ENF43R2V interchangeable in automotive applications?

A: Yes. Both carry AEC-Q200 automotive qualification and meet identical electrical and thermal specifications. Selection between them depends on supply availability and procurement preferences.

Q: Does the 0.004" height difference between parts affect PCB assembly?

A: No. All parts fall within the 0805 (2012 Metric) package specification. Standard reflow soldering processes accommodate this dimensional variation without impact on assembly yield or reliability.

Q: Which substitute has the best availability?

A: Panasonic ERJ-6ENF43R2V offers the highest inventory (119,336 pcs), followed by YAGEO RC0805FR-0743R2L (110,297 pcs). Stackpole RMCF0805FT43R2 has limited stock (2,244 pcs).

Q: Are all substitutes ROHS3 compliant?

A: ERJ-6ENF43R2V, RC0805FR-0743R2L, and RMCF0805FT43R2 are confirmed ROHS3 compliant. All parts are REACH unaffected and carry EAR99 ECCN classification.
