Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC3216F4643CS is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Resistance value (464 kOhms), tolerance (±1%), power rating (0.25W), and temperature coefficient (±100ppm/°C) must match exactly. These parameters define the functional performance in circuit applications.

Mechanical Parameters: Package format (1206 / 3216 Metric) and number of terminations (2) ensure physical and electrical compatibility on printed circuit boards. Dimensional variations within supplier device package specifications are acceptable.

Environmental & Compliance Parameters: Operating temperature range (-55°C ~ 155°C), Moisture Sensitivity Level (MSL 1), RoHS3 compliance, and REACH status must be equivalent or superior. These parameters ensure reliability and regulatory conformance.

All identified substitute parts meet these criteria and are classified as either Direct Manufacturer equivalents or Similar Manufacturer alternatives based on feature alignment.

Parameter Comparison

Engineering Selection Recommendations

RC1206FR-07464KL (YAGEO): This part is classified as a Direct Manufacturer equivalent with Active product status. All electrical and mechanical parameters align with the RC3216F4643CS. YAGEO RC_L series components maintain identical tolerance, power rating, and temperature characteristics. This substitute is suitable for general industrial applications requiring standard thick film resistor performance.

CRCW1206464KFKEA (Vishay Dale): This part is classified as a Similar Manufacturer alternative with Active product status. In addition to matching all core electrical and mechanical specifications, this component carries AEC-Q200 automotive qualification. The CRCW series is suitable for applications requiring automotive-grade reliability and environmental stress screening. Selection of this part is appropriate when automotive compliance or enhanced reliability margins are required.

ERJ-8ENF4643V (Panasonic): This part is classified as a Similar Manufacturer alternative with Not For New Designs product status. While all electrical and mechanical parameters match the RC3216F4643CS and AEC-Q200 automotive qualification is provided, the Not For New Designs designation indicates this component is in end-of-life phase. This part is suitable only for legacy system maintenance, repair, and obsolescence management where existing designs require component replacement.

Frequently Asked Questions (FAQ)

Q: Can RC1206FR-07464KL replace RC3216F4643CS in new designs?

A: Yes. RC1206FR-07464KL meets all electrical specifications (464 kOhms ±1%, 0.25W, ±100ppm/°C), mechanical requirements (1206 package, 2 terminations), and environmental standards (MSL 1, RoHS3, -55°C ~ 155°C). Both components are Active product status. Direct substitution is supported.

Q: What is the difference between CRCW1206464KFKEA and RC3216F4643CS?

A: Both parts are electrically and mechanically equivalent. CRCW1206464KFKEA includes AEC-Q200 automotive qualification, which RC3216F4643CS does not specify. This additional qualification makes CRCW1206464KFKEA suitable for automotive applications requiring enhanced reliability screening and environmental stress testing.

Q: Why is ERJ-8ENF4643V marked "Not For New Designs"?

A: ERJ-8ENF4643V carries Not For New Designs product status, indicating the component is in end-of-life phase. While electrically and mechanically equivalent to RC3216F4643CS, this part should be used only for repair and maintenance of existing systems. New circuit designs should use Active status alternatives such as RC1206FR-07464KL or CRCW1206464KFKEA.

Q: Are dimensional variations between substitute parts significant?

A: Dimensional variations exist within acceptable tolerances. RC3216F4643CS and CRCW1206464KFKEA measure 0.126" L x 0.063" W (3.20mm x 1.60mm), while RC1206FR-07464KL measures 0.122" L x 0.063" W (3.10mm x 1.60mm). Height variations range from 0.024" to 0.028" maximum seated height. These variations remain within 1206 package specification and do not affect PCB layout or assembly compatibility.

Q: Do all substitute parts have identical moisture sensitivity ratings?

A: Yes. All substitute parts carry MSL Level 1 (Unlimited) rating, identical to RC3216F4643CS. This rating indicates no moisture sensitivity restrictions and unlimited shelf life under standard storage conditions.

Q: Which substitute part should be selected for automotive applications?

A: CRCW1206464KFKEA is the recommended selection for automotive applications. This part carries AEC-Q200 qualification, which specifies automotive-grade reliability, environmental stress screening, and failure rate requirements. RC1206FR-07464KL is suitable for general industrial use. ERJ-8ENF4643V should not be used in new automotive designs due to Not For New Designs status.
