Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following mandatory parameters: resistance value (3 MOhms), tolerance (±1%), power rating (0.063W), package type (0402), composition (thick film), operating temperature range (-55°C to 155°C), and compliance certifications (ROHS3, REACH Unaffected, EAR99). All identified substitutes meet these core requirements. Substitutes are grouped by functional classification: direct equivalents share identical electrical and environmental specifications; upgrade variants add automotive AEC-Q200 qualification; similar variants maintain core specifications with alternative temperature coefficient or packaging options.

Parameter Comparison

Engineering Selection Recommendations

RC0402FR-073ML (YAGEO) functions as a direct equivalent substitute. This part maintains identical electrical specifications, temperature coefficient (±100ppm/°C), and moisture resistance characteristics. Packaging differs as Cut Tape with Digi-Reel® versus Tape & Reel, requiring verification of assembly line compatibility. High inventory availability (44433 units) supports procurement continuity.

RMCF0402FT3M00 (Stackpole Electronics Inc) qualifies as an upgrade substitute with automotive AEC-Q200 certification. Core electrical parameters remain equivalent; however, temperature coefficient is ±200ppm/°C versus ±100ppm/°C on the primary part. This specification difference is acceptable for applications where tighter temperature stability is not required. AEC-Q200 qualification enables use in automotive and high-reliability applications. Tape & Reel packaging aligns with original specification. Largest inventory availability (387609 units) provides maximum supply security.

CRCW04023M00FKED (Vishay Dale) qualifies as a similar substitute with automotive AEC-Q200 certification. Electrical specifications and temperature coefficient (±100ppm/°C) match the primary part exactly. AEC-Q200 qualification supports automotive applications. Tape & Reel packaging is compatible with original specification. Inventory availability (68587 units) is adequate for production requirements.

All substitutes maintain ROHS3 compliance and REACH Unaffected status, ensuring regulatory alignment with the original part.

Frequently Asked Questions (FAQ)

Q: Can RC0402FR-073ML replace RC1005F305CS in production assembly?

A: Yes. RC0402FR-073ML is electrically and mechanically equivalent. The primary difference is packaging format: Cut Tape with Digi-Reel® versus Tape & Reel. Verify that your pick-and-place equipment supports the alternative packaging format before implementation.

Q: What is the significance of AEC-Q200 qualification on RMCF0402FT3M00 and CRCW04023M00FKED?

A: AEC-Q200 is an automotive industry qualification standard. Parts bearing this certification have undergone additional reliability testing and are approved for automotive applications. If your application does not require automotive qualification, non-AEC-Q200 parts are functionally suitable.

Q: Why does RMCF0402FT3M00 have a ±200ppm/°C temperature coefficient while others are ±100ppm/°C?

A: Temperature coefficient defines how resistance changes with temperature. RMCF0402FT3M00 exhibits twice the temperature sensitivity. For applications requiring tight resistance stability across temperature extremes, select parts with ±100ppm/°C specification. For general-purpose applications, ±200ppm/°C is acceptable.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All four parts (RC1005F305CS, RC0402FR-073ML, RMCF0402FT3M00, CRCW04023M00FKED) are ROHS3 compliant and REACH Unaffected, meeting current environmental regulations.

Q: Which substitute offers the best supply availability?

A: RMCF0402FT3M00 (Stackpole) has the highest inventory at 387609 units, followed by CRCW04023M00FKED (Vishay Dale) at 68587 units and RC0402FR-073ML (YAGEO) at 44433 units. For long-term supply security, RMCF0402FT3M00 is the optimal choice.

Q: Can I mix different manufacturers' parts in the same production batch?

A: Yes. All substitutes meet identical electrical and environmental specifications. However, document the substitution in your bill of materials and quality records for traceability. Verify that your assembly process accommodates any packaging format differences.

Q: What is Moisture Sensitivity Level (MSL) 1?

A: MSL 1 indicates unlimited shelf life without moisture baking requirements. All four parts carry MSL 1 rating, meaning they can be stored indefinitely under normal conditions without special handling or pre-reflow baking procedures.
