Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC3216F4991CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 4.99 kOhms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Package format: 1206 (3216 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Number of terminations: 2

Compliance Considerations:

• RoHS3 compliance required for direct substitution in regulated applications
• MSL 1 rating ensures unlimited shelf life compatibility
• REACH status alignment recommended for supply chain consistency

Substitute parts are categorized as Direct, Upgrade, or Similar based on additional features and certifications beyond the mandatory parameters. Direct substitutes maintain identical specifications. Upgrade substitutes add automotive AEC-Q200 qualification. Similar substitutes may include enhanced features such as pulse withstanding capability or alternative packaging formats while maintaining core electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Functionally Equivalent):

CR1206-FX-4991ELF (Bourns Inc.) and RC1206FR-074K99L (YAGEO) are direct functional equivalents to RC3216F4991CS. Both maintain identical electrical specifications, package format, and ROHS3 compliance. Selection between these options depends on supply chain availability and packaging format preference (Tape & Reel versus Cut Tape & Digi-Reel).

Upgrade Substitutes (Enhanced Capability):

AC1206FR-074K99L (YAGEO), CRCW12064K99FKEA (Vishay Dale), and RMCF1206FT4K99 (Stackpole Electronics Inc) provide automotive AEC-Q200 qualification in addition to base specifications. These parts are suitable for applications requiring automotive-grade reliability and are fully ROHS3 compliant with Active product status. These upgrades introduce no functional incompatibility while providing enhanced qualification documentation.

Similar Substitutes (Feature Variants):

CRCW12064K99FKEAHP (Vishay Dale) offers increased power rating (0.75W versus 0.25W) with pulse withstanding capability, suitable for applications requiring higher transient energy handling within the same 1206 package footprint. This part maintains ROHS3 compliance and Active status.

CRCW12064K99FKTA (Vishay Dale) matches electrical and mechanical specifications but carries RoHS non-compliant status and REACH Affected designation, limiting use in regulated markets.

ERJ-8ENF4991V (Panasonic Electronic Components) is classified as Not For New Designs, indicating obsolescence trajectory. While currently available with ROHS3 compliance and AEC-Q200 qualification, this part should not be selected for new circuit designs.

Recommended Selection Priority:

1. CR1206-FX-4991ELF or RC1206FR-074K99L for direct replacement in non-automotive applications
2. AC1206FR-074K99L, CRCW12064K99FKEA, or RMCF1206FT4K99 for automotive or high-reliability applications
3. Avoid CRCW12064K99FKTA due to RoHS non-compliance
4. Avoid ERJ-8ENF4991V for new designs

Frequently Asked Questions (FAQ)

Q: Can CR1206-FX-4991ELF directly replace RC3216F4991CS without circuit redesign?

A: Yes. CR1206-FX-4991ELF is a direct functional equivalent with identical resistance (4.99 kΩ), tolerance (±1%), power rating (0.25W), package format (1206), temperature coefficient (±100ppm/°C), and operating range (-55°C to 155°C). Both are ROHS3 compliant with MSL 1 rating. No circuit modifications are required.

Q: What is the difference between Direct, Upgrade, and Similar substitute categories?

A: Direct substitutes maintain all electrical and mechanical specifications identically. Upgrade substitutes add certifications (such as automotive AEC-Q200) without changing core performance. Similar substitutes may include feature enhancements (such as higher power rating or pulse withstanding) or packaging format variations while maintaining core compatibility.

Q: Are automotive-qualified parts (AEC-Q200) backward compatible with general industrial applications?

A: Yes. Automotive AEC-Q200 qualified parts such as AC1206FR-074K99L and RMCF1206FT4K99 meet or exceed general industrial specifications. These parts can be used in non-automotive applications without functional issues. The additional qualification represents enhanced reliability documentation and manufacturing process control.

Q: Why is CRCW12064K99FKTA not recommended despite matching specifications?

A: CRCW12064K99FKTA is RoHS non-compliant and REACH Affected. These regulatory status differences restrict use in markets with mandatory RoHS compliance requirements (EU, China, and many others). RC3216F4991CS is ROHS3 compliant, making RoHS-compliant substitutes necessary for regulatory alignment.

Q: What does "Not For New Designs" mean for ERJ-8ENF4991V?

A: This designation indicates the part is in obsolescence phase. While currently available, the manufacturer does not recommend its use in new circuit designs. Existing inventory may be depleted, and long-term availability is not guaranteed. New designs should select from Active status parts.

Q: Can CRCW12064K99FKEAHP (0.75W) replace RC3216F4991CS (0.25W) in existing circuits?

A: CRCW12064K99FKEAHP is mechanically and electrically compatible with identical resistance, tolerance, package, and temperature characteristics. The higher power rating (0.75W versus 0.25W) provides additional thermal margin and does not create functional incompatibility. However, circuit thermal analysis should confirm that the higher power dissipation capability does not introduce unintended thermal effects in the specific application.

Q: What packaging format differences exist among substitute parts?

A: RC3216F4991CS uses standard packaging (not specified in detail). CR1206-FX-4991ELF uses Tape & Reel (TR). RC1206FR-074K99L uses Cut Tape (CT) & Digi-Reel. AC1206FR-074K99L, CRCW12064K99FKEA, CRCW12064K99FKEAHP, and RMCF1206FT4K99 use Tape & Reel (TR). CRCW12064K99FKTA uses Cut Tape (CT) & Digi-Reel. Packaging format affects supply chain logistics but does not impact electrical or mechanical compatibility.

Q: Are all substitute parts available in equivalent quantities?

A: Inventory levels vary significantly. CR1206-FX-4991ELF has 79,753 pieces available. RMCF1206FT4K99 has 92,992 pieces. CRCW12064K99FKEA has 68,193 pieces. RC1206FR-074K99L has 62,095 pieces. AC1206FR-074K99L has 8,929 pieces. CRCW12064K99FKTA has 27,911 pieces. ERJ-8ENF4991V has 16,061 pieces. Supply availability should be verified with component distributors for specific project requirements.
