Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC3216F6493CS is determined by strict equivalence across the following parameters:

Core Electrical Parameters: Resistance value (649 kOhms), tolerance (±1%), and power rating (0.25W) must match exactly. These parameters define the functional performance in the circuit.

Mechanical Compatibility: Package type (1206 / 3216 Metric) and number of terminations (2) must be identical to ensure PCB footprint compatibility without layout modifications.

Environmental Specifications: Temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), composition (Thick Film), and moisture resistance characteristics must align with the original part requirements.

Regulatory Compliance: RoHS3 compliance and Moisture Sensitivity Level 1 (Unlimited) are mandatory for substitution in regulated applications.

Substitute parts are classified as Direct Equivalents when all parameters match the main part. Similar parts may include automotive-grade certifications (AEC-Q200) or dimensional variations within acceptable tolerances that do not affect circuit performance or PCB assembly.

ERJ-8ENF6493V (Panasonic Electronic Components): This part meets all electrical and mechanical specifications with AEC-Q200 automotive certification. However, the ERJ-8ENF6493V carries a "Not For New Designs" product status designation. This part is suitable for legacy system maintenance and field replacement only. New circuit designs should not incorporate this component. Stock availability is 44958 pieces.

For new designs, RC1206FR-07649KL or CRCW1206649KFKEA are the recommended selections. For automotive applications specifically, CRCW1206649KFKEA is the preferred choice due to active status and AEC-Q200 certification.

Frequently Asked Questions (FAQ)

Q: Can RC1206FR-07649KL replace RC3216F6493CS in existing designs?

A: Yes. RC1206FR-07649KL is a direct substitute. Both parts share identical resistance (649 kOhms), tolerance (±1%), power rating (0.25W), package format (1206), temperature coefficient (±100ppm/°C), and operating range (-55°C ~ 155°C). PCB footprint compatibility is guaranteed without layout modifications.

Q: What is the difference between CRCW1206649KFKEA and the main part?

A: CRCW1206649KFKEA matches all electrical and mechanical specifications of RC3216F6493CS. The primary distinction is AEC-Q200 automotive qualification, which adds reliability assurance for automotive applications. Physical dimensions are identical (1206 package), and both maintain ROHS3 compliance and MSL 1 rating.

Q: Why is ERJ-8ENF6493V marked "Not For New Designs"?

A: The "Not For New Designs" status indicates that Panasonic has discontinued active development and promotion of this part line. While ERJ-8ENF6493V meets all technical specifications and remains electrically compatible, it is reserved for legacy system support and field replacement. New circuit designs must select from parts with Active status: RC1206FR-07649KL or CRCW1206649KFKEA.

Q: Are dimensional variations between substitute parts significant?

A: Dimensional variations are within acceptable tolerances for 1206 package components. RC3216F6493CS measures 0.126" L x 0.063" W (3.20mm x 1.60mm) with 0.026" max height. RC1206FR-07649KL measures 0.122" L x 0.063" W (3.10mm x 1.60mm) with 0.026" max height. CRCW1206649KFKEA matches the main part at 0.126" x 0.063" with 0.024" max height. These variations do not affect PCB assembly or circuit performance.

Q: Do all substitute parts carry the same moisture sensitivity rating?

A: Yes. RC3216F6493CS, RC1206FR-07649KL, CRCW1206649KFKEA, and ERJ-8ENF6493V all carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage or handling.

Q: Which substitute part offers the highest stock availability?

A: ERJ-8ENF6493V has the highest inventory at 44958 pieces. However, due to its "Not For New Designs" status, RC1206FR-07649KL (6394 pieces) or CRCW1206649KFKEA (15798 pieces) are preferred for active projects.
