Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC3216F45R3CS is determined by strict equivalence across the following parameters: resistance value (45.3 Ohms), tolerance (±1%), power rating (0.25W), package format (1206), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), moisture sensitivity level (MSL 1), and RoHS3 compliance status. All identified substitute parts maintain these electrical and environmental specifications without deviation. Packaging format variations (Tape & Reel versus Cut Tape) do not affect functional interchangeability. Dimensional tolerances within the 1206 package specification are acceptable. Product status transitions and automotive certifications (AEC-Q200) represent additional qualifications that do not disqualify substitution but indicate enhanced application scope.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Active Product Status):

CR1206-FX-45R3ELF (Bourns Inc.) and RC1206FR-0745R3L (YAGEO) are direct functional equivalents with Active product status. Both maintain identical electrical specifications and environmental ratings. Selection between these options is based on supply chain availability and packaging preference (Tape & Reel format for both).

Enhanced Specification Substitute (Automotive Qualified):

CRCW120645R3FKEA (Vishay Dale) provides equivalent electrical performance with additional AEC-Q200 automotive qualification. This component is suitable for applications requiring automotive-grade reliability without functional modification to the circuit design.

Legacy Substitute (Not For New Designs):

ERJ-8ENF45R3V (Panasonic Electronic Components) meets all electrical and environmental specifications but carries "Not For New Designs" product status. This component is suitable only for replacement or repair of existing assemblies where design continuity is required. New circuit designs should not incorporate this part number.

Frequently Asked Questions (FAQ)

Q: Can CR1206-FX-45R3ELF replace RC3216F45R3CS in existing designs?

A: Yes. Both components share identical resistance (45.3 Ohms), tolerance (±1%), power rating (0.25W), package format (1206), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and RoHS3 compliance. Functional interchangeability is confirmed.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) and Cut Tape (CT) represent different supply formats for the same component. Tape & Reel is supplied on continuous carrier tape suitable for automated assembly equipment. Cut Tape is supplied in shorter tape segments. The electrical and mechanical specifications of the component remain identical regardless of packaging format.

Q: Why is ERJ-8ENF45R3V marked "Not For New Designs"?

A: "Not For New Designs" indicates the manufacturer has discontinued active development and recommends alternative components for new circuit designs. This designation does not affect electrical performance or compatibility with existing designs. The component remains suitable for replacement applications.

Q: Does AEC-Q200 certification affect substitution compatibility?

A: AEC-Q200 is an automotive qualification standard that certifies enhanced reliability testing. Components with AEC-Q200 certification (CRCW120645R3FKEA and ERJ-8ENF45R3V) are functionally equivalent to non-automotive versions. AEC-Q200 certification represents an additional qualification level and does not prevent substitution in non-automotive applications.

Q: Are dimensional variations within the 1206 package acceptable?

A: Yes. All substitute parts conform to 1206 (3216 Metric) package specification. Minor dimensional variations (length 0.122" to 0.126", height 0.024" to 0.030") fall within standard package tolerances and do not affect PCB footprint compatibility or functional performance.

Q: What compliance certifications apply to all substitute parts?

A: All identified substitute parts maintain ROHS3 compliance, REACH Unaffected status, and MSL 1 (Unlimited) moisture sensitivity rating. These certifications are consistent across all options and confirm environmental and regulatory equivalence.
