Key Parameters

Substitute Part Grouping Explanation

Substitution for the MCR03EZPFX2610 is determined by strict equivalence across the following parameters:

• Resistance value: 261 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

Parts are classified as Direct Substitutes when all electrical and mechanical parameters match exactly. The RC0603FR-07261RL from YAGEO is classified as a Similar substitute due to feature differences (Moisture Resistant vs. Automotive AEC-Q200 rating).

Parameter Comparison

Engineering Selection Recommendations

For direct replacement of the discontinued MCR03EZPFX2610, the following active parts provide full electrical and mechanical equivalence:

CRCW0603261RFKEA (Vishay Dale), ERJ-3EKF2610V (Panasonic Electronic Components), RMCF0603FG261R (Stackpole Electronics Inc), and RMCF0603FT261R (Stackpole Electronics Inc) are all qualified direct substitutes. All maintain AEC-Q200 automotive rating, ROHS3 compliance, and identical electrical specifications.

The RC0603FR-07261RL (YAGEO) is functionally equivalent in electrical performance and package but carries a Moisture Resistant feature designation rather than explicit AEC-Q200 automotive certification. This part remains ROHS3 compliant and suitable for applications where moisture resistance is beneficial.

Selection among direct substitutes should prioritize inventory availability and supply chain logistics. RMCF0603FT261R offers the highest inventory level at 114,873 pieces.

Frequently Asked Questions (FAQ)

Q: Can RC0603FR-07261RL be used as a direct replacement for MCR03EZPFX2610?

A: RC0603FR-07261RL matches all electrical parameters (261 Ω, ±1%, 0.1W, ±100ppm/°C, -55°C to 155°C) and package specifications (0603). However, it is designated as Moisture Resistant rather than carrying explicit AEC-Q200 automotive certification. For automotive applications requiring AEC-Q200 compliance, use CRCW0603261RFKEA, ERJ-3EKF2610V, RMCF0603FG261R, or RMCF0603FT261R instead.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts and the original MCR03EZPFX2610 are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: Do packaging differences affect substitutability?

A: All parts use the 0603 (1608 Metric) package. Minor dimensional variations exist (length 1.55mm to 1.60mm, height 0.50mm to 0.55mm) but remain within standard 0603 footprint tolerances and do not affect PCB assembly compatibility.

Q: Which substitute offers the best supply availability?

A: RMCF0603FT261R from Stackpole Electronics Inc has the highest inventory at 114,873 pieces, followed by ERJ-3EKF2610V from Panasonic at 89,386 pieces.

Q: Are temperature coefficient and operating range identical across all substitutes?

A: Yes. All parts maintain ±100ppm/°C temperature coefficient and -55°C to 155°C operating temperature range.
