Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MCR03ERTF7870 is determined by strict equivalence across the following parameters:

• Resistance value: 787 Ohms (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 (required for regulatory alignment)
• Moisture sensitivity: MSL 1 (required for handling compatibility)

All substitute parts listed below meet these criteria. Variations in features (moisture resistance, automotive qualification) represent enhancements that do not affect core electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts are direct electrical and mechanical equivalents to the MCR03ERTF7870. Selection among these options depends on application requirements and supply chain considerations:

CR0603-FX-7870ELF (Bourns Inc.) — Active product with moisture-resistant construction. Suitable for general industrial applications requiring enhanced environmental protection.

CRCW0603787RFKEA (Vishay Dale) — Active product with automotive AEC-Q200 qualification. Required for automotive and safety-critical applications where AEC-Q200 certification is mandated.

RC0603FR-07787RL (YAGEO) — Active product with moisture-resistant construction and highest inventory availability (86,743 pcs). Suitable for high-volume production and general industrial applications.

RMCF0603FT787R (Stackpole Electronics Inc.) — Active product with automotive AEC-Q200 qualification. Required for automotive and safety-critical applications where AEC-Q200 certification is mandated.

All substitute parts maintain identical electrical performance, thermal characteristics, and regulatory compliance (ROHS3, REACH Unaffected, EAR99) with the original MCR03ERTF7870.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts as a direct replacement for MCR03ERTF7870?

A: Yes. All listed substitute parts are electrically and mechanically equivalent. They share identical resistance (787 Ohms), tolerance (±1%), power rating (0.1W), package (0603), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C). PCB layout and footprint compatibility is guaranteed.

Q: What is the difference between standard and automotive-qualified versions?

A: CRCW0603787RFKEA and RMCF0603FT787R carry AEC-Q200 automotive qualification, indicating compliance with automotive reliability and quality standards. These are required for automotive applications. Standard versions (CR0603-FX-7870ELF and RC0603FR-07787RL) are suitable for industrial and consumer applications.

Q: Does moisture resistance affect electrical performance?

A: No. Moisture-resistant variants (CR0603-FX-7870ELF and RC0603FR-07787RL) provide enhanced environmental protection but maintain identical electrical specifications. Moisture Sensitivity Level (MSL 1) is equivalent across all parts.

Q: Which substitute offers the best availability?

A: RC0603FR-07787RL (YAGEO) has the highest inventory (86,743 pcs), followed by CRCW0603787RFKEA (Vishay Dale, 20,328 pcs), RMCF0603FT787R (Stackpole, 19,305 pcs), and CR0603-FX-7870ELF (Bourns, 14,507 pcs).

Q: Are all substitutes RoHS3 compliant?

A: Yes. All substitute parts are ROHS3 Compliant and REACH Unaffected, matching the regulatory status of the original MCR03ERTF7870.

Q: Can I mix different manufacturers in the same design?

A: Yes. All substitute parts meet identical electrical and mechanical specifications. Mixed sourcing is permissible from a technical standpoint, though single-source procurement may simplify supply chain management.
