Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RCS3216J395CS are identified based on strict electrical and mechanical parameter matching. The primary substitution criteria are:

Electrical Parameters:

• Resistance value: 3.9 MOhms (exact match required)
• Power rating: 0.25W (1/4W) (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C to 155°C (exact match required)
• Composition: Thick Film (exact match required)

Mechanical Parameters:

• Package / Case: 1206 (3216 Metric) (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

Compliance Parameters:

• RoHS Status: ROHS3 Compliant (exact match required)

Tolerance variations (±5% vs. ±1%) are permitted when the substitute part maintains all other electrical and mechanical specifications. Substitute parts with tighter tolerance (±1%) are functionally compatible with applications designed for ±5% tolerance. Packaging format (Tape & Reel vs. bulk) does not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts maintain Active product status and ROHS3 compliance, ensuring long-term availability and regulatory conformance. Selection among substitute parts should be based on the following criteria:

RC1206JR-073M9L (YAGEO): Direct tolerance match (±5%) to the RCS3216J395CS. This part is the closest functional equivalent when tolerance specification is a primary consideration. Inventory availability is 10356 pieces.

RC1206FR-073M9L (YAGEO): Offers tighter tolerance (±1%) while maintaining all other electrical and mechanical specifications. This part is suitable for applications where improved tolerance performance is beneficial. Inventory availability is 49527 pieces.

CRCW12063M90FKEA (Vishay Dale): Provides ±1% tolerance with automotive AEC-Q200 qualification. Height-seated dimension is 0.024" (0.60mm), which is lower than the main part. This part is suitable for space-constrained applications. Inventory availability is 13653 pieces.

KTR18EZPF3904 (Rohm Semiconductor): Offers ±1% tolerance with automotive AEC-Q200 qualification and high voltage features. Height-seated dimension is 0.026" (0.65mm). This part is suitable for automotive and high-voltage applications. Inventory availability is 30669 pieces.

Frequently Asked Questions (FAQ)

Q: Can RC1206JR-073M9L replace RCS3216J395CS directly?

A: Yes. RC1206JR-073M9L maintains identical tolerance (±5%), resistance value (3.9 MOhms), power rating (0.25W), package (1206), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and compliance status (ROHS3). Mechanical dimensions are within acceptable variation for 1206 package footprints.

Q: What is the difference between ±5% and ±1% tolerance parts?

A: Tolerance specifies the maximum deviation from the nominal resistance value. A ±5% part on 3.9 MOhms allows resistance between 3.705 MOhms and 4.095 MOhms. A ±1% part allows resistance between 3.861 MOhms and 3.939 MOhms. Parts with ±1% tolerance are suitable for applications requiring tighter resistance control and are functionally compatible with designs specified for ±5% tolerance.

Q: Are there package compatibility concerns between substitute parts?

A: All substitute parts use the 1206 (3216 Metric) package. Dimensional variations exist: RCS3216J395CS and CRCW12063M90FKEA measure 0.126" L, while RC1206FR-073M9L and RC1206JR-073M9L measure 0.122" L. Height-seated dimensions range from 0.024" to 0.026". These variations are within standard 1206 package tolerances and do not affect PCB footprint compatibility.

Q: Which substitute part has the highest inventory availability?

A: RC1206FR-073M9L (YAGEO) has the highest inventory with 49527 pieces in stock, followed by KTR18EZPF3904 (Rohm Semiconductor) with 30669 pieces.

Q: Are automotive-qualified parts (AEC-Q200) suitable for non-automotive applications?

A: Yes. Automotive-qualified parts (CRCW12063M90FKEA and KTR18EZPF3904) meet or exceed specifications for general industrial and commercial applications. AEC-Q200 qualification indicates enhanced reliability testing and is not restrictive for non-automotive use.

Q: What does MSL 1 (Unlimited) mean?

A: Moisture Sensitivity Level 1 indicates the component has unlimited shelf life and does not require special moisture-control storage or handling procedures. All listed parts share this specification.
