Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1005F4222CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 42.2 kOhms
• Tolerance: ±1%
• Package / Case: 0402 (1005 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100 ppm/°C
• Operating Temperature Range: -55°C to 155°C
• Terminations: 2
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation:

• Power Rating: Substitute parts rated at 0.063W (1/16W) or higher are acceptable. Parts with higher power ratings provide equivalent or superior thermal performance in the same package footprint.
• Packaging Format: Both Tape & Reel (TR) and Cut Tape (CT) formats are compatible for assembly operations.
• Compliance Status: Parts must maintain ROHS3 compliance or equivalent regulatory standing.

All identified substitute parts meet these criteria and are electrically and mechanically interchangeable with the RC1005F4222CS in standard PCB assembly applications.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (Preferred for Standard Applications):

CR0402-FX-4222GLF (Bourns Inc.) and RC0402FR-0742K2L (YAGEO) are direct functional equivalents to the RC1005F4222CS. Both parts match all critical electrical parameters and maintain ROHS3 compliance. CR0402-FX-4222GLF offers the highest inventory availability at 79,560 units. RC0402FR-0742K2L includes moisture-resistant construction matching the original part specification and maintains 185,191 units in stock.

Upgrade Option (Enhanced Performance):

ERJ-2RKF4222X (Panasonic Electronic Components) provides a power rating upgrade from 0.063W to 0.1W while maintaining identical resistance, tolerance, and temperature characteristics. This part carries Automotive AEC-Q200 qualification and is suitable for applications requiring enhanced thermal margin. Packaging is available in Cut Tape (CT) & Digi-Reel® format with 134,324 units in inventory.

Automotive-Qualified Alternatives (Regulated Applications):

AC0402FR-0742K2L (YAGEO), CRCW040242K2FKED (Vishay Dale), and RMCF0402FT42K2 (Stackpole Electronics Inc) all carry Automotive AEC-Q200 certification. These parts are suitable for automotive and mission-critical applications. AC0402FR-0742K2L combines AEC-Q200 qualification with moisture-resistant construction. CRCW040242K2FKED and RMCF0402FT42K2 maintain ROHS3 compliance with AEC-Q200 ratings.

Non-Compliant Part (Restricted Use):

CRCW040242K2FKTD (Vishay Dale) is marked as RoHS non-compliant and REACH Affected. This part is not suitable for applications subject to RoHS3 regulatory requirements and should be avoided for new designs or regulated markets.

Frequently Asked Questions (FAQ)

Q: Can I substitute CR0402-FX-4222GLF for RC1005F4222CS in my design?

A: Yes. CR0402-FX-4222GLF is a direct equivalent. Both parts share identical resistance (42.2 kOhms), tolerance (±1%), power rating (0.063W), package (0402), temperature coefficient (±100 ppm/°C), and operating range (-55°C to 155°C). Both are ROHS3 compliant with MSL 1 rating. The parts are electrically and mechanically interchangeable.

Q: What is the difference between RC0402FR-0742K2L and CR0402-FX-4222GLF?

A: Both are direct equivalents to RC1005F4222CS with identical electrical specifications. RC0402FR-0742K2L is manufactured by YAGEO and includes moisture-resistant construction. CR0402-FX-4222GLF is manufactured by Bourns Inc. without specified moisture-resistant features. Selection between these parts depends on supplier availability and design requirements for moisture resistance.

Q: Can I use ERJ-2RKF4222X as a substitute?

A: Yes, with the following consideration: ERJ-2RKF4222X has a higher power rating (0.1W versus 0.063W). This upgrade is electrically compatible and provides enhanced thermal performance in the same 0402 package. The part carries Automotive AEC-Q200 qualification. Use this part when higher power dissipation margin is beneficial or when automotive qualification is required.

Q: Are automotive-qualified parts (AEC-Q200) compatible with standard applications?

A: Yes. Automotive AEC-Q200 qualified parts such as AC0402FR-0742K2L, CRCW040242K2FKED, and RMCF0402FT42K2 meet or exceed the electrical and reliability specifications of standard industrial parts. These parts are suitable for any application requiring the 42.2 kOhms ±1% specification and provide additional qualification assurance.

Q: Why should I avoid CRCW040242K2FKTD?

A: CRCW040242K2FKTD is marked as RoHS non-compliant and REACH Affected. This part does not meet current regulatory requirements for RoHS3 compliance. It should not be used in new designs or applications subject to RoHS3 regulations. Use CRCW040242K2FKED instead, which is the RoHS3 compliant variant from the same manufacturer.

Q: Does packaging format (Tape & Reel vs. Cut Tape) affect electrical performance?

A: No. Packaging format affects only handling, storage, and assembly logistics. Tape & Reel (TR) and Cut Tape (CT) formats contain identical components. ERJ-2RKF4222X is available in Cut Tape (CT) & Digi-Reel® format while other substitutes use Tape & Reel (TR). Both formats are compatible with standard SMD assembly equipment.

Q: Can I mix different manufacturers' parts in the same PCB assembly?

A: Yes. All identified substitute parts meet identical electrical and mechanical specifications. Mixing manufacturers in the same assembly is acceptable from an engineering standpoint. However, verify that your procurement and quality assurance processes support multi-source component strategies.

Q: What inventory levels should I consider for supply chain planning?

A: Current inventory levels are: RC1005F4222CS (1,004 units), CR0402-FX-4222GLF (79,560 units), RC0402FR-0742K2L (185,191 units), ERJ-2RKF4222X (134,324 units), AC0402FR-0742K2L (13,247 units), CRCW040242K2FKED (87,703 units), CRCW040242K2FKTD (10,271 units), and RMCF0402FT42K2 (90,249 units). RC0402FR-0742K2L and ERJ-2RKF4222X offer the highest availability for long-term supply assurance.
