Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RG2012V-202-W-T5 is determined by the following critical parameters:

Electrical Equivalence Requirements:

• Resistance value: 2 kOhms (exact match required)
• Power rating: 0.125W minimum (equal or greater acceptable)
• Temperature coefficient: ±5ppm/°C (matching specification)
• Operating temperature range: -55°C ~ 155°C minimum (equal or greater range acceptable)
• Composition: Thin film construction

Mechanical Compatibility Requirements:

• Package format: 0805 (2012 Metric) (exact match required)
• Number of terminations: 2 (exact match required)
• Physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm) (exact match required)

Regulatory & Compliance Requirements:

• Automotive AEC-Q200 rating (required for automotive applications)
• RoHS3 compliance (required)
• Moisture Sensitivity Level 1 (required)

The RNCF0805TKY2K00 from Stackpole Electronics Inc qualifies as a substitute part because it maintains all critical electrical parameters, identical mechanical compatibility, and equivalent regulatory compliance. The tolerance specification of ±0.01% on the substitute part represents an improvement over the ±0.05% tolerance of the main part, providing enhanced precision capability.

Parameter Comparison

Engineering Selection Recommendations

Both the RG2012V-202-W-T5 and RNCF0805TKY2K00 are active production components with full automotive AEC-Q200 qualification and ROHS3 compliance. Selection between these parts is based on application-specific requirements and supply chain considerations.

The RG2012V-202-W-T5 features anti-sulfur coating, which provides enhanced protection in corrosive environments. This characteristic is specific to the Susumu RG series and should be retained if the application operates in sulfur-rich or high-humidity industrial environments.

The RNCF0805TKY2K00 provides superior tolerance performance at ±0.01%, compared to the ±0.05% tolerance of the main part. This enhanced precision is suitable for applications requiring tighter resistance accuracy. The substitute part has a maximum seated height of 0.026" (0.65mm) compared to 0.020" (0.50mm) for the main part; this difference must be evaluated against PCB layout constraints and component clearance requirements.

Both parts are suitable for automotive applications operating across the -55°C to 155°C temperature range and maintain identical electrical performance characteristics. Component selection should prioritize availability, cost considerations, and specific environmental protection requirements of the target application.

Frequently Asked Questions (FAQ)

Q: Can the RNCF0805TKY2K00 be used as a direct replacement for the RG2012V-202-W-T5?

A: Yes, the RNCF0805TKY2K00 qualifies as a direct substitute. Both parts share identical resistance values, power ratings, package formats, temperature coefficients, and operating temperature ranges. Both maintain AEC-Q200 automotive qualification and ROHS3 compliance. The substitute part provides improved tolerance performance at ±0.01% versus ±0.05%.

Q: What is the significance of the tolerance difference between these parts?

A: The RG2012V-202-W-T5 specifies ±0.05% tolerance, while the RNCF0805TKY2K00 specifies ±0.01% tolerance. The substitute part's tighter tolerance represents enhanced precision capability. Applications requiring strict resistance accuracy benefit from the improved specification. Applications with relaxed tolerance requirements are unaffected by this difference.

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

A: The maximum seated height differs between parts: RG2012V-202-W-T5 is 0.020" (0.50mm) maximum, while RNCF0805TKY2K00 is 0.026" (0.65mm) maximum. This 0.006" (0.15mm) height difference must be evaluated against PCB clearance requirements, particularly in applications with restricted vertical space or component stacking constraints.

Q: Does the anti-sulfur coating of the RG2012V-202-W-T5 affect substitution decisions?

A: The anti-sulfur coating is a specific feature of the Susumu RG series. The RNCF0805TKY2K00 does not include this coating. Applications operating in sulfur-rich or highly corrosive environments should retain the RG2012V-202-W-T5. Standard industrial and automotive applications without specific sulfur exposure requirements are unaffected by this difference.

Q: Are both parts suitable for automotive applications?

A: Yes, both the RG2012V-202-W-T5 and RNCF0805TKY2K00 carry AEC-Q200 automotive qualification. Both are suitable for automotive applications operating within the -55°C to 155°C temperature range. Both maintain ROHS3 compliance and Moisture Sensitivity Level 1 rating.

Q: What packaging format is used for both parts?

A: Both parts are supplied in 0805 (2012 Metric) package format in Tape & Reel (TR) configuration. The package dimensions are identical at 0.079" L x 0.049" W (2.00mm x 1.25mm), ensuring mechanical compatibility in PCB assembly processes.

Q: Can these parts be used interchangeably in high-precision measurement circuits?

A: The RNCF0805TKY2K00 with ±0.01% tolerance is preferred for high-precision measurement circuits requiring tight resistance accuracy. The RG2012V-202-W-T5 with ±0.05% tolerance is suitable for general-purpose applications where tolerance requirements are less stringent. Circuit design specifications determine which tolerance grade is appropriate.
