Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC3216F6490CS is determined by strict alignment of the following parameters:

Electrical Specifications: Resistance value (649 Ohms), tolerance (±1%), and power rating (0.25W) must be identical. Temperature coefficient (±100ppm/°C) and operating temperature range (-55°C ~ 155°C) establish thermal performance equivalence.

Mechanical Compatibility: Package designation (1206 / 3216 Metric) and number of terminations (2) ensure physical and electrical interface compatibility. Dimensional variations within the 1206 standard (length 0.122" to 0.126", width 0.063", height 0.024" to 0.030") are acceptable as they fall within standard PCB footprint tolerances.

Regulatory Compliance: ROHS3 compliance and REACH unaffected status are mandatory. MSL 1 rating ensures moisture sensitivity equivalence.

Composition: Thick film construction is required for thermal and frequency response consistency.

All five substitute parts meet these criteria and are classified as direct equivalents or upgrades based on additional certifications.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (Active Status, Standard Industrial):

CR1206-FX-6490ELF (Bourns Inc.) and RC1206FR-07649RL (YAGEO) are direct functional equivalents with active product status. Both maintain identical electrical and thermal specifications with standard industrial moisture resistance. Selection between these and the original RC3216F6490CS depends on supply chain availability and procurement preferences, as all three are functionally interchangeable.

Upgrade Option (Active Status, Automotive Qualified):

AC1206FR-07649RL (YAGEO) is an upgrade substitute with AEC-Q200 automotive qualification. This part is suitable for applications requiring automotive-grade reliability while maintaining all standard industrial specifications. Use this part when designs require enhanced quality assurance or automotive supply chain compliance.

Alternative with Automotive Qualification (Active Status):

CRCW1206649RFKEA (Vishay Dale) provides AEC-Q200 automotive qualification as an alternative upgrade path. This part is suitable for automotive applications and maintains active production status.

Legacy Component (Not For New Designs):

ERJ-8ENF6490V (Panasonic Electronic Components) carries "Not For New Designs" status despite meeting all electrical and mechanical specifications. This part is available in high inventory (72,874 pieces) but should not be selected for new circuit designs. Use only for replacement or repair of existing assemblies where the original part number is specified.

Frequently Asked Questions (FAQ)

Q: Can I substitute RC3216F6490CS with CR1206-FX-6490ELF in my circuit?

A: Yes. Both parts share identical resistance (649 Ohms), tolerance (±1%), power rating (0.25W), package (1206), temperature coefficient (±100ppm/°C), and operating range (-55°C ~ 155°C). Electrical and thermal performance are equivalent. Physical dimensions fall within standard 1206 footprint tolerances.

Q: What is the difference between RC1206FR-07649RL and AC1206FR-07649RL?

A: Both are YAGEO 649 Ohm 1% 1/4W 1206 resistors with identical electrical specifications. AC1206FR-07649RL includes AEC-Q200 automotive qualification, making it suitable for automotive applications. RC1206FR-07649RL is standard industrial grade. Select AC1206FR-07649RL for automotive designs; either part works for general industrial applications.

Q: Why is ERJ-8ENF6490V marked "Not For New Designs"?

A: This Panasonic part meets all electrical and mechanical specifications but carries obsolescence status. Manufacturers designate parts "Not For New Designs" when transitioning product lines or discontinuing support. Use ERJ-8ENF6490V only for repair or replacement of existing assemblies. For new designs, select from active status alternatives: CR1206-FX-6490ELF, RC1206FR-07649RL, AC1206FR-07649RL, or CRCW1206649RFKEA.

Q: Are there dimensional differences between substitute parts?

A: Minor dimensional variations exist within 1206 standard tolerances. Length ranges from 0.122" to 0.126", height from 0.024" to 0.030". These variations are within PCB footprint design margins and do not affect compatibility. All parts meet the 1206 (3216 Metric) package specification.

Q: Which substitute should I choose for automotive applications?

A: Select AC1206FR-07649RL (YAGEO) or CRCW1206649RFKEA (Vishay Dale). Both carry AEC-Q200 automotive qualification and active production status. ERJ-8ENF6490V also has AEC-Q200 rating but is not recommended for new designs.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All listed substitutes and the original RC3216F6490CS are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
