Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F3481CS is determined by the following mandatory parameters:

Electrical Parameters:

• Resistance value: 3.48 kOhms
• Tolerance: ±1%
• Power rating: 1W
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 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

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

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (Active Status): CRCW25123K48FKEG (Vishay Dale) and RMCF2512FT3K48 (Stackpole Electronics Inc) are both Active product status components with identical electrical and mechanical specifications to the RC6432F3481CS. Both include AEC-Q200 automotive qualification. Selection between these two substitutes depends on supplier availability and packaging requirements (Tape & Reel format).

Alternative Selection (Not For New Designs): ERJ-1TNF3481U (Panasonic Electronic Components) meets all electrical and mechanical substitution criteria but carries "Not For New Designs" product status. This component is suitable for replacement applications and legacy system maintenance only.

Compliance Considerations: All substitute parts maintain ROHS3 compliance, MSL Level 1 rating, and identical operating temperature ranges. Dimensional variations within the 2512 package specification (height range 0.026" to 0.028") do not affect PCB assembly compatibility.

Frequently Asked Questions (FAQ)

Q: Can CRCW25123K48FKEG directly replace RC6432F3481CS on existing PCBs?

A: Yes. Both components share identical electrical specifications (3.48kΩ ±1% 1W), package designation (2512/6432 metric), and thermal characteristics (±100ppm/°C, -55°C to 155°C). Physical dimensions are compatible with standard 2512 footprints. The primary difference is packaging format (Tape & Reel vs. bulk) and optional AEC-Q200 automotive certification on the Vishay part.

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

A: AEC-Q200 is an automotive qualification standard. Substitute parts bearing this certification (CRCW25123K48FKEG and RMCF2512FT3K48) have undergone additional reliability testing for automotive applications. This certification does not affect general-purpose circuit compatibility but indicates enhanced quality assurance for demanding environments.

Q: Why is ERJ-1TNF3481U marked "Not For New Designs"?

A: "Not For New Designs" status indicates the manufacturer has discontinued active development and recommends alternative parts for new product development. However, the component remains functionally equivalent and suitable for replacement in existing applications where RC6432F3481CS is currently installed.

Q: Are there dimensional differences between substitute parts?

A: Minor dimensional variations exist within the 2512 package specification. Length ranges from 0.248" to 0.252" (6.30mm to 6.40mm) and height from 0.026" to 0.028" (0.66mm to 0.70mm). These variations fall within standard PCB footprint tolerances and do not affect assembly or electrical performance.

Q: What packaging formats are available for these substitutes?

A: RC6432F3481CS is supplied in bulk packaging. Substitute parts CRCW25123K48FKEG, ERJ-1TNF3481U, and RMCF2512FT3K48 are available in Tape & Reel (TR) format. Tape & Reel packaging is standard for automated assembly processes and does not affect component electrical or mechanical properties.

Q: Do all substitute parts maintain the same moisture sensitivity rating?

A: Yes. All listed substitutes maintain MSL Level 1 (Unlimited) rating, identical to the RC6432F3481CS. This indicates no moisture sensitivity restrictions and unlimited shelf life under standard storage conditions.
