Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MCR03EZPFX6813 is determined by strict equivalence across the following parameters:

• Resistance Value: 681 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power Rating: 0.1W / 1/10W (exact match required)
• Package: 0603 (1608 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature Coefficient: ±100ppm/°C (exact match required)
• Operating Temperature Range: -55°C ~ 155°C (exact match required)
• RoHS Compliance: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

All identified substitute parts meet these criteria. Parts designated as "Direct" substitutes additionally maintain AEC-Q200 automotive certification. Parts designated as "Similar" maintain all electrical and mechanical parameters but feature moisture-resistant construction instead of automotive-specific qualification.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (AEC-Q200 Certified):

• CRCW0603681KFKEA (Vishay Dale): Active product with full AEC-Q200 automotive certification. Suitable for applications requiring maintained automotive qualification. Available in Tape & Reel packaging with 13914 units in stock.

• ERJ-3EKF6813V (Panasonic Electronic Components): Active product with full AEC-Q200 automotive certification. Highest inventory availability at 93387 units. Suitable for high-volume production requirements.

• RMCF0603FT681K (Stackpole Electronics Inc): Active product with full AEC-Q200 automotive certification. Largest inventory at 244872 units. Recommended for applications prioritizing supply chain continuity.

Similar Substitutes (Moisture-Resistant, Non-Automotive):

• CR0603-FX-6813ELF (Bourns Inc.): Active product with moisture-resistant construction. Suitable for applications where automotive certification is not required. Available in Tape & Reel with 20398 units in stock.

• RC0603FR-07681KL (YAGEO): Active product with moisture-resistant construction. High inventory at 104726 units. Suitable for cost-sensitive applications without automotive requirements.

• RC1608F6813CS (Samsung Electro-Mechanics): Active product with moisture-resistant construction. Available in Cut Tape packaging with 1388 units in stock. Suitable for lower-volume applications.

Selection between direct and similar substitutes depends on whether AEC-Q200 automotive certification is required for the end application.

Frequently Asked Questions (FAQ)

Q: Can I use a similar substitute part in place of the original MCR03EZPFX6813?

A: Similar substitutes maintain all electrical and mechanical parameters (resistance, tolerance, power rating, package, temperature coefficient, and operating range) but lack AEC-Q200 automotive certification. Use is permissible only if automotive qualification is not a design requirement.

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

A: Direct substitutes carry AEC-Q200 automotive certification identical to the original part. Similar substitutes feature moisture-resistant construction but do not carry automotive qualification. Both categories meet all electrical and mechanical specifications.

Q: Are there packaging differences between substitute parts?

A: Most substitutes are supplied in Tape & Reel (TR) packaging. RC1608F6813CS is available in Cut Tape (CT) packaging. All parts use the same 0603 (1608 Metric) package footprint and are mechanically compatible.

Q: Which substitute offers the best supply availability?

A: RMCF0603FT681K (Stackpole Electronics Inc) offers the highest inventory at 244872 units, followed by RC0603FR-07681KL (YAGEO) at 104726 units.

Q: Can I mix substitute parts from different manufacturers in the same assembly?

A: Yes. All substitute parts meet identical electrical and mechanical specifications. Mixed sourcing is permissible from a functional standpoint, though design documentation should reflect the approved part list.

Q: What is the significance of Moisture Sensitivity Level 1?

A: MSL 1 indicates unlimited shelf life without moisture-related degradation. All parts, including both original and substitutes, carry this rating and require no special moisture-control handling.
