Key Parameters

Substitute Part Grouping Explanation

Substitution of the RC3216F3091CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 3.09 kOhms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Package: 1206 (3216 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Moisture sensitivity level: 1 (Unlimited)
• RoHS compliance: ROHS3

All identified substitute parts meet these mandatory parameters. Substitute parts are further categorized as Direct Substitutes (functionally identical with standard moisture-resistant features) or Similar Substitutes (functionally identical with additional automotive AEC-Q200 qualification). Physical dimensions show minor variations within acceptable tolerances for 1206 package specifications.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Recommended for New Designs):

CR1206-FX-3091ELF (Bourns Inc.) and RC1206FR-073K09L (YAGEO) are direct functional equivalents with active product status. Both parts maintain identical electrical specifications and moisture-resistant thick film construction. CR1206-FX-3091ELF offers the highest inventory availability at 25,813 pieces. RC1206FR-073K09L provides an alternative with 4,400 pieces in stock.

Similar Substitutes (Automotive Applications):

CRCW12063K09FKEA (Vishay Dale) and ERJ-8ENF3091V (Panasonic Electronic Components) are functionally equivalent with additional AEC-Q200 automotive qualification. CRCW12063K09FKEA is recommended for new automotive designs with 28,443 pieces available. ERJ-8ENF3091V carries a "Not For New Designs" status and should be used only for legacy system maintenance or replacement applications where existing qualification documentation references this part number.

Selection Criteria:

• For standard industrial applications: Select CR1206-FX-3091ELF or RC1206FR-073K09L
• For automotive applications: Select CRCW12063K09FKEA
• For legacy system replacement only: ERJ-8ENF3091V

Frequently Asked Questions (FAQ)

Q: Can CR1206-FX-3091ELF replace RC3216F3091CS in all applications?

A: Yes. CR1206-FX-3091ELF meets all mandatory electrical and mechanical parameters: 3.09 kOhms ±1%, 0.25W power rating, 1206 package, thick film composition, ±100ppm/°C temperature coefficient, -55°C to 155°C operating range, MSL 1, and ROHS3 compliance. Both parts are in active production status.

Q: What is the difference between direct and similar substitutes?

A: Direct substitutes (CR1206-FX-3091ELF and RC1206FR-073K09L) provide standard moisture-resistant thick film construction. Similar substitutes (CRCW12063K09FKEA and ERJ-8ENF3091V) include additional AEC-Q200 automotive qualification. All four parts are electrically and mechanically equivalent for the specified resistance, tolerance, and power rating.

Q: Are there physical dimension differences between substitute parts?

A: Minor variations exist within 1206 package tolerances. Length ranges from 0.122" to 0.126" (3.10mm to 3.20mm), and height ranges from 0.024" to 0.030" (0.60mm to 0.75mm). These variations are within standard 1206 package specifications and do not affect PCB layout or assembly compatibility.

Q: Why is ERJ-8ENF3091V marked "Not For New Designs"?

A: ERJ-8ENF3091V carries a "Not For New Designs" status from Panasonic Electronic Components. This part should be used only for replacement or maintenance of existing systems where this specific part number is already qualified. For new designs, select CR1206-FX-3091ELF, RC1206FR-073K09L, or CRCW12063K09FKEA.

Q: Which substitute part has the highest inventory availability?

A: CR1206-FX-3091ELF (Bourns Inc.) has the highest inventory with 25,813 pieces in stock, followed by CRCW12063K09FKEA (Vishay Dale) with 28,443 pieces. Both parts are suitable for immediate procurement.

Q: Can automotive-qualified parts be used in non-automotive applications?

A: Yes. CRCW12063K09FKEA and ERJ-8ENF3091V meet all standard specifications and can be used in non-automotive applications. Automotive qualification represents an additional quality assurance level and does not restrict use in other applications.

Q: Are all substitute parts REACH compliant?

A: Yes. All substitute parts listed (CR1206-FX-3091ELF, RC1206FR-073K09L, CRCW12063K09FKEA, and ERJ-8ENF3091V) are REACH Unaffected and ROHS3 compliant, meeting current environmental and regulatory requirements.
