Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment with the following core parameters: resistance value (14.3 kOhms), tolerance (±1%), package type (2512/6432 Metric), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and compliance certifications (ROHS3, REACH Unaffected).

Upgrade Substitute (Direct Replacement with Enhanced Features): AC2512FK-0714K3L meets all core electrical and mechanical parameters while adding automotive AEC-Q200 qualification. Power rating remains 1W. Packaging is Tape & Reel format.

Similar Substitutes (Compatible with Parameter Variations): CRCW251214K3FKEGHP maintains all core parameters but increases power rating to 1.5W and adds automotive AEC-Q200 qualification with pulse withstanding capability. Dimensions vary slightly within acceptable tolerances.

ERJ-1TNF1432U matches all core electrical parameters and package specifications with automotive AEC-Q200 qualification. Product status is Not For New Designs. Power rating is 1W. Dimensions vary slightly within acceptable tolerances.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement with Automotive Applications: AC2512FK-0714K3L is the primary upgrade substitute. It maintains all electrical and mechanical specifications of the RC6432F1432CS while adding automotive AEC-Q200 qualification. Both parts are Active in production status. This part is suitable for designs requiring automotive-grade components without power rating modifications.

For Applications Requiring Enhanced Power Dissipation: CRCW251214K3FKEGHP provides a 1.5W power rating compared to the 1W specification of the main part. This higher power rating accommodates applications with increased thermal demands. The part includes automotive AEC-Q200 qualification and pulse withstanding capability. All core electrical parameters remain identical. This part is Active in production status.

For Legacy System Maintenance: ERJ-1TNF1432U matches all core electrical and mechanical parameters with automotive AEC-Q200 qualification. However, this part carries a Not For New Designs status, indicating it is suitable only for sustaining existing production or maintenance applications. High inventory availability (17,295 units) supports legacy system support requirements.

Compliance Considerations: All substitute parts maintain ROHS3 compliance and REACH Unaffected status, matching the regulatory posture of the main part. Moisture Sensitivity Level 1 (Unlimited) is consistent across all options, supporting standard handling and storage procedures.

Frequently Asked Questions (FAQ)

Q: Can AC2512FK-0714K3L be used as a direct replacement for RC6432F1432CS? A: Yes. AC2512FK-0714K3L maintains identical resistance (14.3 kOhms), tolerance (±1%), power rating (1W), package (2512), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C). The addition of automotive AEC-Q200 qualification does not prevent use in non-automotive applications.

Q: What is the difference between the 1W and 1.5W power ratings? A: CRCW251214K3FKEGHP is rated for 1.5W continuous power dissipation, compared to 1W for the main part and AC2512FK-0714K3L. The 1.5W rating accommodates higher thermal loads. All other electrical parameters remain identical. Selection depends on circuit power dissipation requirements.

Q: Why is ERJ-1TNF1432U marked as Not For New Designs? A: This designation indicates the manufacturer has discontinued active development and recommends against use in new product designs. However, the part remains available for sustaining existing production and maintenance applications. For new designs, AC2512FK-0714K3L or CRCW251214K3FKEGHP are preferred.

Q: Are there packaging format differences between these parts? A: RC6432F1432CS uses standard packaging (format not specified). AC2512FK-0714K3L is supplied in Tape & Reel (TR) format. CRCW251214K3FKEGHP is supplied in Cut Tape (CT) & Digi-Reel® format. ERJ-1TNF1432U is supplied in Tape & Reel (TR) format. Packaging format does not affect electrical or mechanical compatibility.

Q: Do all substitute parts meet moisture resistance requirements? A: RC6432F1432CS and AC2512FK-0714K3L explicitly specify moisture resistance. CRCW251214K3FKEGHP and ERJ-1TNF1432U do not list moisture resistance as a feature. All parts maintain Moisture Sensitivity Level 1 (Unlimited), indicating standard handling procedures apply.

Q: Which substitute part has the highest inventory availability? A: ERJ-1TNF1432U has 17,295 units in stock, followed by CRCW251214K3FKEGHP with 6,692 units and AC2512FK-0714K3L with 7,566 units. Inventory levels support component sourcing decisions for volume requirements.
