Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F4994CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 4.99 MOhms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Package type: 1206 (3216 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Number of terminations: 2
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

All identified substitute parts meet these mandatory parameters. Variations in physical dimensions (length, width, height) and additional features (such as automotive AEC-Q200 qualification or high-voltage capability) do not disqualify substitution but represent secondary differentiators for specific application contexts.

Parameter Comparison

Engineering Selection Recommendations

All four parts listed—RCS3216F4994CS, CRCW12064M99FKEA, KTR18EZPF4994, and RC1206FR-074M99L—are electrically and mechanically equivalent for applications requiring a 4.99 MOhms ±1% 0.25W 1206 thick film resistor. All parts maintain Active product status and ROHS3 compliance.

Selection Considerations Based on Provided Specifications:

The CRCW12064M99FKEA (Vishay Dale) and KTR18EZPF4994 (Rohm) include Automotive AEC-Q200 qualification, which is relevant for automotive-grade applications. The KTR18EZPF4994 additionally specifies high-voltage capability. The RC1206FR-074M99L (YAGEO) and RCS3216F4994CS both specify moisture-resistant properties.

Physical dimension variations exist: RC1206FR-074M99L has a length of 0.122" (3.10mm) compared to 0.126" (3.20mm) for the other parts. Height-seated maximum values range from 0.024" to 0.026", representing minor variations within standard 1206 package tolerances.

Inventory availability differs significantly: RC1206FR-074M99L has 47,064 units in stock, KTR18EZPF4994 has 23,311 units, CRCW12064M99FKEA has 8,844 units, and RCS3216F4994CS has 873 units.

Frequently Asked Questions (FAQ)

Q: Can CRCW12064M99FKEA replace RCS3216F4994CS in any application?

A: Yes. Both parts are electrically and mechanically equivalent with identical resistance, tolerance, power rating, package type, temperature coefficient, and operating temperature range. The CRCW12064M99FKEA includes Automotive AEC-Q200 qualification, which does not restrict its use in non-automotive applications.

Q: What is the significance of the AEC-Q200 rating on KTR18EZPF4994 and CRCW12064M99FKEA?

A: AEC-Q200 is an automotive qualification standard. Parts bearing this rating meet automotive reliability and quality requirements. These parts are suitable for both automotive and general-purpose applications.

Q: Are there physical dimension differences that affect PCB layout?

A: Minor variations exist. RC1206FR-074M99L has a length of 3.10mm compared to 3.20mm for other parts. Height-seated maximum values range from 0.60mm to 0.66mm. These variations fall within standard 1206 package tolerances and do not typically affect PCB design compatibility.

Q: Do all substitute parts have the same moisture sensitivity level?

A: Yes. All four parts have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Which part should be selected based on inventory availability?

A: RC1206FR-074M99L offers the highest inventory (47,064 units), followed by KTR18EZPF4994 (23,311 units). Selection based on availability depends on procurement lead time requirements and supply chain considerations.

Q: Are all parts REACH compliant?

A: Yes. All four parts have REACH Unaffected status, indicating compliance with REACH regulations.
