Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC3216F185CS is determined by strict equivalence across the following critical parameters:

Electrical Specifications: Resistance value of 1.8 MOhms, tolerance of ±1%, and power rating of 0.25W (1/4W) must be identical.

Package Compatibility: All substitute parts must use 1206 (3216 Metric) package format to ensure PCB footprint compatibility and assembly process alignment.

Environmental Ratings: Operating temperature range of -55°C ~ 155°C, temperature coefficient of ±100ppm/°C, and Moisture Sensitivity Level 1 (Unlimited) are required for functional equivalence.

Composition & Construction: Thick film construction with moisture-resistant properties must be maintained.

Compliance Standards: ROHS3 compliance and REACH Unaffected status are mandatory for regulatory equivalence.

All identified substitute parts meet these criteria without exception. Additional features such as Automotive AEC-Q200 certification or High Voltage capability represent enhanced specifications that do not disqualify parts from substitution but indicate upgraded performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (Active Status): RC1206FR-071M8L (YAGEO) is the direct functional equivalent with Active product status, identical electrical and mechanical specifications, and standard moisture-resistant construction. This part is suitable for general applications requiring 1.8 MOhms ±1% 0.25W 1206 resistors.

Automotive Applications: AC1206FR-071M8L (YAGEO), CRCW12061M80FKEA (Vishay Dale), and KTR18EZPF1804 (Rohm Semiconductor) are qualified substitutes with Automotive AEC-Q200 certification. These parts are appropriate for automotive circuit designs where AEC-Q200 compliance is specified or required.

High Voltage Applications: KTR18EZPF1804 (Rohm Semiconductor) includes High Voltage capability in addition to AEC-Q200 certification, providing enhanced performance for high-voltage circuit environments.

Legacy Design Consideration: ERJ-8ENF1804V (Panasonic Electronic Components) carries "Not For New Designs" status. This part remains functionally equivalent but should not be selected for new product development. Existing designs using this part may continue operation with this component.

All substitute parts maintain ROHS3 compliance and REACH Unaffected status, ensuring regulatory alignment with the original RC3216F185CS specification.

Frequently Asked Questions (FAQ)

Q: Can RC1206FR-071M8L replace RC3216F185CS directly on the PCB?

A: Yes. RC1206FR-071M8L is a direct functional equivalent with identical resistance (1.8 MOhms), tolerance (±1%), power rating (0.25W), package format (1206), and environmental specifications. PCB footprint compatibility is confirmed.

Q: What is the difference between RC1206FR-071M8L and AC1206FR-071M8L?

A: Both parts are manufactured by YAGEO with identical electrical and mechanical specifications. AC1206FR-071M8L includes Automotive AEC-Q200 certification, making it suitable for automotive applications. RC1206FR-071M8L is the standard industrial-grade equivalent without automotive qualification.

Q: Is ERJ-8ENF1804V still usable in new designs?

A: ERJ-8ENF1804V carries "Not For New Designs" product status. While functionally equivalent, this part should not be selected for new product development. Use RC1206FR-071M8L, AC1206FR-071M8L, CRCW12061M80FKEA, or KTR18EZPF1804 for new designs.

Q: Which substitute part is best for automotive applications?

A: AC1206FR-071M8L, CRCW12061M80FKEA, and KTR18EZPF1804 all carry Automotive AEC-Q200 certification. KTR18EZPF1804 provides additional High Voltage capability if required by the application.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All identified substitute parts (RC1206FR-071M8L, AC1206FR-071M8L, CRCW12061M80FKEA, ERJ-8ENF1804V, and KTR18EZPF1804) are ROHS3 compliant and REACH Unaffected, matching the regulatory status of RC3216F185CS.

Q: What is Moisture Sensitivity Level 1?

A: MSL 1 indicates unlimited shelf life without moisture-related degradation. All listed parts maintain MSL 1 rating, ensuring consistent handling and storage requirements.

Q: Can I mix different substitute parts in the same circuit?

A: Yes. All substitute parts meet identical electrical specifications (1.8 MOhms ±1%, 0.25W) and environmental ratings (-55°C ~ 155°C, ±100ppm/°C). Mixed usage is functionally compatible. However, for automotive designs, maintain consistent AEC-Q200 certification across all resistor selections.
