Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F4020CS is determined by strict alignment of the following parameters:

Electrical Parameters (Critical):

• Resistance value: 402 Ohms
• Tolerance: ±1%
• Power rating: 1W
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters (Critical):

• Package type: 2512 (6432 Metric)
• Physical dimensions: 0.248" L x 0.126" W (6.30mm x 3.20mm) with allowable tolerance
• Height seated maximum: 0.026" to 0.028" (0.66mm to 0.70mm)
• Termination count: 2

Material & Composition (Critical):

• Thick film construction

Compliance Parameters (Required):

• RoHS3 compliance
• MSL rating: 1 (Unlimited)

All identified substitute parts meet these criteria. Variations in packaging format (Tape & Reel vs. bulk) and automotive certifications (AEC-Q200) do not affect electrical or mechanical substitutability.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

CRCW2512402RFKEG (Vishay Dale) and RMCF2512FT402R (Stackpole Electronics Inc) are recommended as primary substitutes. Both components maintain Active product status, ensuring long-term availability and manufacturing support. Both are AEC-Q200 automotive qualified, providing additional reliability assurance for demanding applications. Inventory availability is substantial for both alternatives.

Secondary Substitute (Legacy Status):

ERJ-1TNF4020U (Panasonic Electronic Components) meets all electrical and mechanical substitution criteria and carries AEC-Q200 automotive qualification. However, this component is classified as Not For New Designs. Use this substitute only when replacing existing components in fielded equipment or when supply constraints on primary alternatives exist. New circuit designs should prioritize Active status alternatives.

Compliance Verification:

All substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) rating, matching the original RC6432F4020CS specifications. No additional environmental or regulatory considerations apply to substitution decisions.

Frequently Asked Questions (FAQ)

Q: Can CRCW2512402RFKEG replace RC6432F4020CS in existing designs?

A: Yes. CRCW2512402RFKEG meets all electrical specifications (402 Ohms ±1%, 1W, ±100ppm/°C, -55°C ~ 155°C operating range) and mechanical requirements (2512 package, compatible dimensions). Both components are ROHS3 compliant with MSL 1 rating. The primary difference is packaging format (Tape & Reel vs. bulk) and automotive AEC-Q200 certification on the Vishay part, which does not prevent substitution.

Q: What is the difference between the height specifications (0.026" vs 0.028")?

A: The RC6432F4020CS specifies maximum seated height of 0.026" (0.66mm), while substitute parts specify 0.028" (0.70mm). This 0.002" (0.04mm) difference is within standard PCB assembly tolerances and does not affect circuit functionality or board layout compatibility for standard applications.

Q: Why is ERJ-1TNF4020U marked "Not For New Designs"?

A: This designation indicates the manufacturer (Panasonic) is transitioning this product line and recommends alternative parts for new circuit designs. The component remains electrically and mechanically equivalent and is suitable for replacement in existing equipment. For new designs, select CRCW2512402RFKEG or RMCF2512FT402R.

Q: Are all substitutes automotive qualified?

A: CRCW2512402RFKEG and ERJ-1TNF4020U carry AEC-Q200 automotive qualification. RMCF2512FT402R also carries AEC-Q200 qualification. The original RC6432F4020CS does not list automotive certification. Automotive qualification on substitutes provides additional reliability assurance but does not prevent use in non-automotive applications.

Q: Can I mix different substitute parts in the same assembly?

A: Yes. All identified substitutes meet identical electrical and mechanical specifications. Mixing different manufacturers in the same assembly does not create compatibility issues. However, standard procurement practice typically specifies a single part number per design to simplify supply chain management and traceability.

Q: What packaging formats are available?

A: RC6432F4020CS is supplied in bulk packaging. CRCW2512402RFKEG, ERJ-1TNF4020U, and RMCF2512FT402R are supplied in Tape & Reel (TR) format. Tape & Reel packaging is standard for automated assembly processes. If bulk packaging is required, consult with the component supplier regarding alternative packaging availability.

Q: Are there any temperature or environmental limitations when substituting?

A: No. All substitute parts maintain the identical operating temperature range (-55°C ~ 155°C), temperature coefficient (±100ppm/°C), and MSL 1 (Unlimited) rating. Environmental performance is equivalent across all identified substitutes.
