Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F1430CS is determined by strict alignment of the following parameters:

Electrical Parameters:

• Resistance value: 143 Ohms
• Tolerance: ±1%
• Power rating: 1W
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C

Mechanical Parameters:

• Package type: 2512 (6432 Metric)
• Number of terminations: 2
• Physical dimensions compatible with 2512 footprint

Compliance Parameters:

• RoHS3 compliance
• Moisture sensitivity level: 1 (Unlimited)
• REACH unaffected status

All identified substitute parts meet these core parameters. Variations in product status, packaging format (Tape & Reel vs. bulk), and optional certifications (such as AEC-Q200 automotive qualification) do not disqualify substitution but indicate application-specific suitability.

Parameter Comparison

Engineering Selection Recommendations

RC6432F1430CS (Samsung Electro-Mechanics) - Primary Selection

The RC6432F1430CS maintains Active product status and is the specified main part. This component is suitable for applications requiring general industrial-grade thick film resistors with moisture resistance and standard compliance certifications.

RMCF2512FT143R (Stackpole Electronics Inc) - Preferred Substitute

The RMCF2512FT143R is classified as Active product status and provides direct electrical and mechanical equivalence to the main part. This substitute includes AEC-Q200 automotive qualification, making it suitable for both general industrial and automotive applications. Physical dimensions match the main part exactly (0.248" L x 0.126" W), with seated height of 0.028" maximum.

ERJ-1TNF1430U (Panasonic Electronic Components) - Alternative Substitute

The ERJ-1TNF1430U is classified as Not For New Designs, indicating this part is in mature or declining production phase. While electrically and mechanically equivalent, this substitute is not recommended for new design implementations. The part includes AEC-Q200 automotive qualification and is suitable for legacy system maintenance or replacement applications only. Physical dimensions show minor variation in length (0.252" vs. 0.248") and seated height (0.028" vs. 0.026"), which remain within 2512 package tolerance specifications.

Frequently Asked Questions (FAQ)

Q: Can RMCF2512FT143R be used as a direct replacement for RC6432F1430CS?

A: Yes. Both parts share identical electrical specifications (143 Ohms ±1%, 1W, ±100ppm/°C, -55°C to 155°C operating range), identical package designation (2512/6432 Metric), and equivalent compliance certifications (ROHS3, REACH Unaffected, MSL 1). Physical dimensions are identical (0.248" L x 0.126" W). The RMCF2512FT143R is Active product status and includes AEC-Q200 automotive qualification.

Q: Why is ERJ-1TNF1430U marked as "Not For New Designs"?

A: Product status classification reflects the manufacturer's production roadmap. "Not For New Designs" indicates the part is in mature phase with potential future discontinuation. While the part remains electrically and mechanically equivalent, it is not recommended for new circuit designs. This classification does not affect compatibility for existing applications or replacement scenarios.

Q: Are there dimensional differences between the three parts?

A: Minor dimensional variations exist within 2512 package tolerance specifications. RC6432F1430CS and RMCF2512FT143R share identical length (0.248" / 6.30mm) and width (0.126" / 3.20mm). ERJ-1TNF1430U shows length of 0.252" (6.40mm) and width of 0.126" (3.20mm). Seated height varies: RC6432F1430CS at 0.026" (0.66mm), while both ERJ-1TNF1430U and RMCF2512FT143R are 0.028" (0.70mm). These variations remain within standard 2512 package specifications and do not affect PCB footprint compatibility.

Q: What is the significance of AEC-Q200 certification on substitute parts?

A: AEC-Q200 is an automotive industry qualification standard. RMCF2512FT143R and ERJ-1TNF1430U include this certification, indicating suitability for automotive applications with enhanced reliability requirements. The main part RC6432F1430CS does not specify AEC-Q200 certification but remains suitable for general industrial applications. AEC-Q200 certification does not disqualify use in non-automotive applications.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, within the constraints of physical board layout. All three parts are electrically identical and share the same 2512 package footprint. Minor height variations (0.026" to 0.028") are within standard PCB assembly tolerances. Verify that board layout accommodates the maximum seated height of 0.028" if substituting RC6432F1430CS with either RMCF2512FT143R or ERJ-1TNF1430U.

Q: What packaging formats are available?

A: RC6432F1430CS is supplied in standard packaging format (specific format not detailed in provided data). RMCF2512FT143R and ERJ-1TNF1430U are supplied in Tape & Reel (TR) format, which is standard for high-volume automated assembly. Packaging format does not affect electrical or mechanical compatibility.

Q: Are all three parts RoHS3 compliant?

A: Yes. RC6432F1430CS, RMCF2512FT143R, and ERJ-1TNF1430U are all ROHS3 compliant with REACH Unaffected status and Moisture Sensitivity Level 1 (Unlimited). All parts meet current environmental and regulatory compliance requirements.
