Key Parameters

Substitute Part Grouping Explanation

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

• Resistance value: 182 Ohms
• Tolerance: ±1%
• Power rating: 0.1W (1/10W)
• Package: 0603 (1608 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

All substitute parts listed below meet these parameters. Direct substitutes maintain AEC-Q200 automotive certification. Similar substitutes meet all electrical and mechanical specifications but feature moisture-resistant composition instead of automotive-specific ratings.

Parameter Comparison

Engineering Selection Recommendations

Direct substitutes CRCW0603182RFKEA (Vishay Dale), ERJ-3EKF1820V (Panasonic), and RMCF0603FT182R (Stackpole) maintain full AEC-Q200 automotive certification and are recommended for applications requiring automotive-grade reliability. All three are in active production with substantial inventory availability.

Similar substitutes CR0603-FX-1820ELF (Bourns) and RC0603FR-07182RL (YAGEO) meet all electrical and mechanical specifications with moisture-resistant composition. These are suitable for non-automotive applications or where moisture resistance is a design requirement. Both are in active production.

All substitute parts are ROHS3 compliant with MSL 1 rating, matching the original part's environmental compliance profile.

Frequently Asked Questions (FAQ)

Q: Can I use CR0603-FX-1820ELF or RC0603FR-07182RL in place of MCR03EZPFX1820 in automotive applications?

A: CR0603-FX-1820ELF and RC0603FR-07182RL are not AEC-Q200 certified. Use these only in non-automotive applications. For automotive circuits, select from CRCW0603182RFKEA, ERJ-3EKF1820V, or RMCF0603FT182R.

Q: Are all substitute parts physically compatible with the original PCB footprint?

A: Yes. All substitute parts use the 0603 (1608 Metric) package. Minor dimensional variations exist (length 1.55mm to 1.60mm, height 0.50mm to 0.55mm), but these fall within standard PCB design tolerances and do not affect assembly or functionality.

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

A: Direct substitutes (Vishay Dale, Panasonic, Stackpole) carry AEC-Q200 automotive certification identical to the original part. Similar substitutes (Bourns, YAGEO) meet all electrical and mechanical specifications but feature moisture-resistant composition without automotive certification.

Q: Which substitute has the best inventory availability?

A: ERJ-3EKF1820V (Panasonic) offers the highest inventory at 270,195 pieces, followed by RC0603FR-07182RL (YAGEO) at 233,291 pieces.

Q: Do all substitutes have the same temperature coefficient and operating range?

A: Yes. All substitute parts maintain ±100ppm/°C temperature coefficient and -55°C to 155°C operating temperature range, matching the original MCR03EZPFX1820 specification.
