Key Parameters

Substitute Part Grouping Explanation

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

Electrical Parameters (Must Match Exactly):

• Resistance value: 1.74 kOhms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C

Mechanical Parameters (Must Match Exactly):

• Package type: 1206 (3216 Metric)
• Number of terminations: 2
• Composition: Thick Film

Compliance Parameters (Must Match or Exceed):

• RoHS3 compliance
• MSL 1 rating
• REACH unaffected status

All substitute parts listed meet these criteria. Parts are categorized as "Direct" substitutes when all parameters match identically, and "Similar" substitutes when additional features (such as automotive AEC-Q200 qualification) are present without compromising base specifications.

Parameter Comparison

Engineering Selection Recommendations

Active Production Status: CR1206-FX-1741ELF (Bourns), RC1206FR-071K74L (YAGEO), and CRCW12061K74FKEA (Vishay Dale) are all in active production and suitable for new designs. The main part RC3216F1741CS (Samsung Electro-Mechanics) maintains active status with 970 units in stock.

Compliance Equivalence: All substitute parts maintain ROHS3 compliance, MSL 1 rating, and REACH unaffected status, matching the environmental and regulatory requirements of the primary component.

Automotive-Qualified Alternatives: CRCW12061K74FKEA and ERJ-8ENF1741V include AEC-Q200 automotive qualification. These parts are suitable for applications requiring automotive-grade reliability without compromising standard specifications.

Inventory Availability: CR1206-FX-1741ELF (Bourns) offers the highest inventory level at 25,789 units. RC1206FR-071K74L (YAGEO) provides 8,422 units. CRCW12061K74FKEA (Vishay Dale) has 1,130 units available. ERJ-8ENF1741V (Panasonic) maintains 58,609 units but is designated "Not For New Designs."

Obsolescence Consideration: ERJ-8ENF1741V is marked "Not For New Designs" and should be avoided for new circuit development, though it remains functionally equivalent for legacy system maintenance.

Frequently Asked Questions (FAQ)

Q: Can CR1206-FX-1741ELF directly replace RC3216F1741CS on a circuit board?

A: Yes. Both components share identical electrical specifications (1.74 kΩ ±1%, 0.25W), temperature coefficient (±100ppm/°C), operating range (-55°C to 155°C), and 1206 package dimensions. Mechanical dimensions are within acceptable tolerance for PCB footprint compatibility.

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

A: Direct substitutes (CR1206-FX-1741ELF, RC1206FR-071K74L) match all base electrical and mechanical parameters identically. Similar substitutes (CRCW12061K74FKEA, ERJ-8ENF1741V) include additional qualifications such as AEC-Q200 automotive certification while maintaining equivalent core specifications.

Q: Why is ERJ-8ENF1741V marked "Not For New Designs"?

A: This designation indicates the part is in mature or declining production phase. While functionally equivalent and currently in inventory, Panasonic recommends alternative parts for new circuit development. Existing designs using this component may continue operation.

Q: Are there dimensional differences between substitute parts?

A: All parts conform to 1206 (3216 Metric) package specification. Minor height variations exist: RC3216F1741CS (0.66mm max), CR1206-FX-1741ELF (0.75mm max), RC1206FR-071K74L (0.65mm max), CRCW12061K74FKEA (0.60mm max), and ERJ-8ENF1741V (0.70mm max). These variations remain within standard PCB assembly tolerances.

Q: Which substitute offers the best long-term availability?

A: RC1206FR-071K74L (YAGEO) and CR1206-FX-1741ELF (Bourns) are both in active production with substantial inventory levels. YAGEO's RC series maintains consistent market presence for industrial applications.

Q: Can automotive-qualified parts (CRCW12061K74FKEA) be used in non-automotive applications?

A: Yes. Automotive-qualified components exceed standard reliability requirements and are fully compatible with general industrial and consumer applications. No performance degradation occurs in non-automotive use.

Q: What packaging formats are available for these substitutes?

A: All substitute parts are supplied in Tape & Reel (TR) format, standard for automated PCB assembly. The main part RC3216F1741CS uses standard packaging notation without specific format designation in provided data.
