Substitute Part Grouping Explanation

Substitute parts for the RC3225F5621CS are qualified based on the following criteria:

Electrical Parameter Matching:

• Resistance value: 5.62 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)

Mechanical Compatibility:

• Package format: 1210 (3225 Metric) (exact match required)
• Number of terminations: 2 (exact match required)

Compliance & Environmental:

• RoHS3 compliance (required)
• Moisture sensitivity level: MSL 1 (required)

Composition:

• Thick film construction (required)

The identified substitute parts ERJ-14NF5621U and ERJ-P14F5621U meet all electrical and mechanical compatibility requirements. Both parts maintain the same resistance value, tolerance, temperature coefficient, and operating temperature range. Both are packaged in 1210 (3225 Metric) format with identical termination configuration. Both achieve RoHS3 compliance and MSL 1 rating. The primary difference is power rating: substitute parts are rated at 0.5W (1/2W) compared to the main part's 0.333W (1/3W), which represents a higher power capability and does not restrict substitution in applications requiring the lower power specification.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: ERJ-P14F5621U

The ERJ-P14F5621U is the recommended substitute for new designs and ongoing production. This part maintains Active product status, ensuring long-term availability and manufacturer support. It provides identical electrical specifications (5.62 kOhms ±1%, ±100ppm/°C, -55°C ~ 155°C operating range) and mechanical compatibility (1210 package, 2 terminations). The higher power rating (0.5W vs. 0.333W) provides additional thermal margin without affecting circuit performance in applications designed for the original specification. Automotive AEC-Q200 qualification and pulse withstanding capability provide enhanced reliability characteristics. RoHS3 compliance and MSL 1 rating match the original part requirements.

Secondary Substitute: ERJ-14NF5621U

The ERJ-14NF5621U provides equivalent electrical and mechanical compatibility with identical specifications to ERJ-P14F5621U. However, this part carries "Not For New Designs" product status, indicating limited future availability and manufacturer support. Selection of this part is appropriate only for legacy system maintenance or replacement applications where design changes are not feasible. Automotive AEC-Q200 qualification is maintained.

Dimensional Considerations

Substitute parts exhibit minor dimensional variations within the 1210 package specification. Width tolerance is 0.098" (2.50mm) compared to the main part's 0.100" (2.55mm), and maximum seated height is 0.028" (0.70mm) compared to 0.026" (0.66mm). These variations remain within standard 1210 package tolerances and do not restrict PCB layout compatibility or assembly processing.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF5621U and ERJ-P14F5621U be used interchangeably with RC3225F5621CS?

A: Both substitute parts meet all electrical and mechanical compatibility requirements. Resistance value, tolerance, temperature coefficient, and operating temperature range are identical. Package format (1210), termination count (2), and compliance ratings (RoHS3, MSL 1) are equivalent. The higher power rating (0.5W vs. 0.333W) does not restrict substitution in circuits designed for the original 0.333W specification.

Q: What is the difference between ERJ-14NF5621U and ERJ-P14F5621U?

A: Both parts share identical electrical specifications and package format. The primary differences are: (1) Product Status—ERJ-P14F5621U is Active while ERJ-14NF5621U is Not For New Designs; (2) Features—ERJ-P14F5621U includes pulse withstanding capability in addition to automotive AEC-Q200 qualification. For new designs, ERJ-P14F5621U is the preferred selection due to active product status and extended feature set.

Q: Are there dimensional compatibility concerns when substituting these parts?

A: Substitute parts exhibit minor dimensional variations within standard 1210 package tolerances. Width is 0.098" (2.50mm) versus 0.100" (2.55mm) for the main part, and maximum seated height is 0.028" (0.70mm) versus 0.026" (0.66mm). These variations do not affect PCB footprint compatibility or standard assembly processes.

Q: Do substitute parts maintain the same compliance certifications?

A: Yes. Both ERJ-14NF5621U and ERJ-P14F5621U are RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level, matching the original RC3225F5621CS specifications. Both achieve automotive AEC-Q200 qualification, which exceeds the moisture resistant classification of the main part.

Q: What is the significance of the higher power rating in substitute parts?

A: Substitute parts are rated at 0.5W (1/2W) compared to the main part's 0.333W (1/3W). This represents increased power dissipation capability and thermal margin. In applications designed for 0.333W operation, the higher rating provides additional safety margin without affecting electrical performance or circuit behavior.

Q: Can these parts be used in automotive applications?

A: Both substitute parts carry automotive AEC-Q200 qualification. The main part (RC3225F5621CS) does not specify automotive qualification. If automotive application requirements exist, substitute parts provide qualified alternatives with enhanced reliability characteristics.
