Key Parameters

Substitute Part Grouping Explanation

Substitution for the MCR03EZPFX5621 is determined by strict equivalence across the following parameters: resistance value (5.62 kOhms), tolerance (±1%), power rating (0.1W), package type (0603 / 1608 Metric), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and compliance certifications (ROHS3, MSL 1).

Direct substitutes maintain all electrical and mechanical specifications including AEC-Q200 automotive rating. Similar substitutes meet all core electrical parameters and package requirements but may differ in specific feature designations (moisture resistant vs. automotive rated) while maintaining equivalent performance characteristics and compliance status.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain full electrical and mechanical compatibility with the MCR03EZPFX5621 across the specified parameters. Direct substitutes CRCW06035K62FKEA, ERJ-3EKF5621V, RMCF0603FG5K62, and RMCF0603FT5K62 carry explicit AEC-Q200 automotive certification matching the original part specification. These direct substitutes are recommended for applications requiring automotive-grade qualification.

Similar substitutes CR0603-FX-5621ELF, RC0603FR-075K62L, and RC1608F5621CS meet all core electrical parameters and package requirements with moisture-resistant thick film composition. These parts are suitable for applications where the specific automotive certification is not a contractual requirement but equivalent electrical performance and environmental stability are necessary.

All substitute options are ROHS3 compliant with MSL 1 rating and maintain the -55°C to 155°C operating temperature range. Selection should be based on application requirements, supply chain availability, and any specific automotive qualification mandates.

Frequently Asked Questions (FAQ)

Q: Can I use a moisture-resistant substitute in place of an AEC-Q200 rated part?

A: Moisture-resistant thick film resistors meet the same electrical specifications and environmental operating range as AEC-Q200 parts. The distinction lies in certification pathway and qualification testing. Use moisture-resistant substitutes only if your application does not contractually require AEC-Q200 certification.

Q: Are all substitute parts in the same 0603 package?

A: Yes. All listed substitutes use the 0603 (1608 Metric) package with identical footprint dimensions (0.063" L x 0.031" W / 1.60mm x 0.80mm nominal), ensuring direct PCB compatibility. Minor dimensional variations exist within manufacturing tolerance but do not affect placement or soldering.

Q: What is the difference between direct and similar substitutes?

A: Direct substitutes maintain AEC-Q200 automotive certification identical to the original MCR03EZPFX5621. Similar substitutes meet all electrical and mechanical parameters but carry moisture-resistant designation instead of automotive rating. Both categories are ROHS3 compliant with MSL 1 and equivalent temperature performance.

Q: Do all substitutes have the same temperature coefficient?

A: Yes. All listed parts maintain ±100ppm/°C temperature coefficient and -55°C to 155°C operating range, ensuring equivalent thermal stability across the specified operating envelope.

Q: Which substitute has the highest inventory availability?

A: RC0603FR-075K62L (YAGEO) shows 1,382,046 pieces in stock, followed by RMCF0603FT5K62 (Stackpole) with 209,437 pieces. Both are active products with established supply chains.
