Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F1690CS is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 169 Ohms
• Tolerance: ±1%
• Package / Case: 2512 (6432 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation:

• Power Rating: Substitutes rated at 1W or higher are acceptable, as higher power ratings provide equivalent or superior thermal performance within the same package footprint.
• Physical dimensions: Minor variations within supplier device package specifications (2512) are acceptable provided the component maintains the same PCB footprint and mounting characteristics.

Identified substitutes are grouped into two categories: Upgrade (higher power rating) and Similar (equivalent power rating with alternative certifications or product status considerations).

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (Direct Equivalent): CRCW2512169RFKEG (Vishay Dale) is the preferred substitute for new designs. This part maintains identical electrical specifications (169 Ohms ±1%, 1W) and package dimensions as the RC6432F1690CS while providing AEC-Q200 automotive qualification. Both components are in active production status, ensuring long-term supply continuity.

Upgrade Option: RHC2512FT169R (Stackpole Electronics Inc) provides a 2W power rating within the same 2512 package footprint. This higher power rating offers improved thermal margin and is suitable for applications requiring enhanced power dissipation capability. The component maintains all other electrical and environmental specifications of the original part.

Legacy / Inventory Consideration: ERJ-1TNF1690U (Panasonic Electronic Components) is marked "Not For New Designs" and should be used only for legacy system maintenance or repair applications where supply of active-status alternatives is constrained. This part maintains full electrical and environmental compatibility but carries product lifecycle restrictions.

Compliance Verification: All identified substitutes maintain ROHS3 compliance, MSL 1 rating, and -55°C to 155°C operating temperature range. Selection between candidates should prioritize active production status and application-specific requirements (automotive AEC-Q200 certification if required).

Frequently Asked Questions (FAQ)

Q: Can RHC2512FT169R (2W) be used as a direct replacement for RC6432F1690CS (1W)? A: Yes. The RHC2512FT169R is a valid substitute with identical resistance, tolerance, package, and temperature specifications. The 2W power rating is a higher specification that provides equivalent or superior performance in the same physical footprint. No circuit modifications are required.

Q: What is the difference between moisture-resistant and AEC-Q200 rated parts? A: Moisture-resistant designation indicates the component meets moisture resistance requirements. AEC-Q200 is an automotive qualification standard that includes moisture resistance testing plus additional automotive-specific reliability and performance criteria. Both feature sets are compatible; AEC-Q200 parts provide additional automotive-grade assurance.

Q: Why is ERJ-1TNF1690U marked "Not For New Designs"? A: This designation indicates the manufacturer has discontinued active development and is transitioning the product line. While the part remains functionally equivalent and is currently in stock, it should not be selected for new product designs due to potential future supply discontinuation. Use this part only for legacy system support.

Q: Are there physical dimension differences between these substitutes? A: All parts use the 2512 (6432 Metric) package with identical PCB footprint. Minor height variations exist (0.66mm to 0.70mm seated height), which do not affect PCB assembly compatibility. Verify clearance in applications with height-constrained layouts.

Q: Which substitute offers the best long-term supply availability? A: CRCW2512169RFKEG (Vishay Dale) and RHC2512FT169R (Stackpole Electronics Inc) are both in active production status with substantial inventory levels (9009 and 5696 units respectively). Both are suitable for long-term supply planning. ERJ-1TNF1690U, despite higher current inventory (24139 units), carries product lifecycle restrictions.

Q: Can these parts be used interchangeably in automotive applications? A: CRCW2512169RFKEG and ERJ-1TNF1690U carry AEC-Q200 automotive qualification. RC6432F1690CS and RHC2512FT169R do not carry explicit automotive certification. Verify automotive qualification requirements for your specific application before selection.
