Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across four critical parameter categories:

Electrical Parameters: Resistance value (46.4 kOhms), tolerance (±1%), power rating (0.25W), and temperature coefficient (±100ppm/°C) must match exactly.

Mechanical Parameters: Package designation (1206 / 3216 Metric) and composition (Thick Film) must be identical. Physical dimensions (length, width, height) may vary within manufacturing tolerances but must not exceed PCB footprint constraints.

Environmental Parameters: Operating temperature range (-55°C ~ 155°C) and Moisture Sensitivity Level (MSL 1) must be maintained.

Compliance Parameters: RoHS3 compliance and REACH unaffected status must be present. Additional certifications (AEC-Q200 automotive qualification) represent enhanced capability and do not disqualify substitution.

All identified substitute parts meet these criteria. Parts designated "Direct" are functionally identical with no additional qualifications. Parts designated "Similar" include automotive AEC-Q200 certification, which exceeds base requirements.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Functionally Equivalent):

CR1206-FX-4642ELF (Bourns Inc.) and RC1206FR-0746K4L (YAGEO) are direct functional equivalents with Active product status. Both maintain identical electrical and environmental specifications. Selection between these and the original RC3216F4642CS depends on supply chain availability and packaging format requirements (Tape & Reel versus Cut Tape).

Similar Substitutes (Enhanced Capability):

CRCW120646K4FKEA (Vishay Dale) and ERJ-8ENF4642V (Panasonic Electronic Components) include Automotive AEC-Q200 certification, indicating qualification for automotive applications with enhanced reliability testing. These components exceed base specification requirements and are suitable for applications requiring automotive-grade components.

Product Status Consideration:

ERJ-8ENF4642V carries "Not For New Designs" status. While electrically and mechanically equivalent, this designation indicates the manufacturer is discontinuing the product line. For new circuit designs, CR1206-FX-4642ELF, RC1206FR-0746K4L, or CRCW120646K4FKEA are preferred to ensure long-term supply continuity.

Compliance Verification:

All substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the original component's regulatory standing.

Frequently Asked Questions (FAQ)

Q: Can CR1206-FX-4642ELF replace RC3216F4642CS directly on the PCB?

A: Yes. Both components share identical 1206 (3216 Metric) package dimensions and electrical specifications (46.4 kOhms ±1%, 0.25W, ±100ppm/°C). Physical dimension variations (height: 0.66mm vs. 0.75mm) remain within standard PCB footprint tolerances and do not affect placement or soldering.

Q: What is the difference between "Direct" and "Similar" substitute classifications?

A: Direct substitutes (Bourns CR1206-FX-4642ELF, YAGEO RC1206FR-0746K4L) match all base electrical and environmental specifications without additional certifications. Similar substitutes (Vishay Dale CRCW120646K4FKEA, Panasonic ERJ-8ENF4642V) include Automotive AEC-Q200 qualification, indicating enhanced reliability testing for automotive applications. Both categories are electrically interchangeable.

Q: Why is ERJ-8ENF4642V marked "Not For New Designs"?

A: This designation indicates Panasonic is discontinuing this product line. While currently in stock and functionally equivalent, new circuit designs should specify alternative parts with Active status (CR1206-FX-4642ELF, RC1206FR-0746K4L, or CRCW120646K4FKEA) to ensure availability throughout the product lifecycle.

Q: Are packaging format differences (Tape & Reel vs. Cut Tape) significant for substitution?

A: Packaging format affects procurement and assembly processes but does not impact electrical or mechanical compatibility. RC1206FR-0746K4L (Cut Tape & Digi-Reel®) may be preferred for lower-volume applications, while CR1206-FX-4642ELF and CRCW120646K4FKEA (Tape & Reel) are optimized for high-volume automated assembly.

Q: Do the automotive AEC-Q200 qualified parts (CRCW120646K4FKEA, ERJ-8ENF4642V) cost more?

A: Pricing is not provided in this reference. Contact component distributors for current pricing. AEC-Q200 qualification typically reflects additional manufacturing and testing costs but provides enhanced reliability documentation for automotive applications.

Q: Can I use CRCW120646K4FKEA in non-automotive applications?

A: Yes. AEC-Q200 certification represents enhanced capability and does not restrict use to automotive applications. CRCW120646K4FKEA is suitable for any application requiring 46.4 kOhms ±1% 0.25W 1206 resistors and provides additional reliability assurance.

Q: What is Moisture Sensitivity Level (MSL) 1, and why is it important?

A: MSL 1 indicates unlimited shelf life without moisture-related degradation. All listed parts maintain MSL 1 rating, ensuring they can be stored and handled without special moisture control measures, matching the original RC3216F4642CS requirements.
