Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RCS3216F42R2CS are qualified based on the following criteria:

Electrical Parameters: Resistance value of 42.2 Ohms, tolerance of ±1%, and power rating of 0.25W (1/4W) must match exactly.

Mechanical Parameters: Package designation of 1206 (3216 Metric) ensures footprint compatibility on printed circuit boards.

Environmental Parameters: Temperature coefficient of ±100ppm/°C and operating temperature range of -55°C to 155°C must be maintained.

Compliance Parameters: ROHS3 compliance and MSL rating of 1 (Unlimited) are required for equivalent substitution.

Composition: Thick film construction is the specified technology.

All identified substitute parts meet these criteria and are therefore suitable for direct replacement in applications where the RCS3216F42R2CS is specified.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: CRCW120642R2FKEA (Vishay Dale) is recommended for new designs. This part maintains Active product status, carries AEC-Q200 automotive qualification, and offers the highest inventory availability at 84,519 pieces. The automotive-grade certification provides additional reliability assurance for demanding applications.

Secondary Selection: RC1206FR-0742R2L (YAGEO) is suitable for applications requiring moisture-resistant thick film construction. This part maintains Active product status with 10,648 pieces in inventory and is compatible with all specified electrical and mechanical parameters.

Legacy Applications: ERJ-8ENF42R2V (Panasonic) carries Not For New Designs status and should be used only in existing production lines or legacy system maintenance where design continuity is required. This part is available with 24,976 pieces in inventory.

All three substitute parts are ROHS3 compliant and maintain the required MSL rating of 1 (Unlimited), ensuring compatibility with standard manufacturing and storage conditions.

Frequently Asked Questions (FAQ)

Q: Can CRCW120642R2FKEA replace RCS3216F42R2CS in all applications?

A: Yes. Both parts share identical electrical specifications (42.2 Ohms ±1%, 0.25W), thermal characteristics (±100ppm/°C, -55°C to 155°C), and package dimensions (1206/3216 Metric). The CRCW part includes AEC-Q200 automotive qualification, which provides additional performance assurance without compromising compatibility.

Q: What is the difference between the substitute parts?

A: All substitute parts meet the core electrical and mechanical requirements. The primary differences are: CRCW120642R2FKEA includes AEC-Q200 automotive certification; ERJ-8ENF42R2V carries Not For New Designs status; RC1206FR-0742R2L emphasizes moisture-resistant construction. Inventory levels and packaging formats (Tape & Reel) also vary.

Q: Are there dimensional differences between these parts?

A: Dimensional variations are minimal. Length ranges from 3.10mm to 3.20mm, width is 1.60mm across all parts, and maximum seated height ranges from 0.60mm to 0.70mm. These variations are within standard PCB footprint tolerances for 1206 packages and do not affect interchangeability.

Q: Which part should be selected for new product designs?

A: CRCW120642R2FKEA is the recommended choice for new designs due to its Active product status and AEC-Q200 automotive qualification. RC1206FR-0742R2L is an alternative for Active product status without automotive requirements.

Q: Why is ERJ-8ENF42R2V marked as Not For New Designs?

A: This designation indicates that Panasonic has transitioned this part to legacy status. While the part remains functionally equivalent and is suitable for existing production lines, new designs should utilize CRCW120642R2FKEA or RC1206FR-0742R2L to ensure long-term supply continuity.

Q: Are all parts ROHS3 compliant?

A: Yes. All four parts, including the main part RCS3216F42R2CS and all three substitutes, are ROHS3 compliant with MSL rating of 1 (Unlimited), meeting current environmental and regulatory requirements.
