Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1005F8873CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 887 kOhms
• Tolerance: ±1%
• Package / Case: 0402 (1005 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• Number of Terminations: 2
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation:

• Power Rating: Substitute parts may equal or exceed the 0.063W specification
• Height - Seated: Substitute parts may vary within mechanical tolerance
• Features: Substitute parts may include additional features (Automotive AEC-Q200, Anti-Sulfur) without affecting base functionality

Four qualified substitute parts meet these criteria across multiple manufacturers, providing supply chain flexibility while maintaining electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Identical Specifications): RC0402FR-07887KL (YAGEO) provides direct equivalence to RC1005F8873CS with matching power rating, package dimensions, and moisture resistant construction. Both parts maintain identical electrical characteristics and compliance certifications.

Upgrade Option (Enhanced Power Rating): ERJ-2RKF8873X (Panasonic Electronic Components) offers increased power dissipation at 0.1W (1/10W) compared to the 0.063W specification of the primary part. This upgrade maintains all other electrical parameters and adds Automotive AEC-Q200 qualification. The higher power rating provides additional thermal margin in applications where power dissipation approaches design limits.

Automotive-Qualified Alternatives: AF0402FR-07887KL (YAGEO), CRCW0402887KFKED (Vishay Dale), and RMCF0402FT887K (Stackpole Electronics Inc) all meet the base electrical specifications while incorporating Automotive AEC-Q200 certification. AF0402FR-07887KL additionally includes anti-sulfur construction. These parts are suitable for applications requiring automotive-grade reliability and environmental protection.

All substitute parts maintain ROHS3 compliance, unlimited moisture sensitivity level (MSL 1), and identical operating temperature ranges. Selection among qualified substitutes depends on supply availability, cost considerations, and application-specific requirements for automotive qualification or enhanced power handling.

Frequently Asked Questions (FAQ)

Q: Can RC0402FR-07887KL replace RC1005F8873CS in any application? A: Yes. RC0402FR-07887KL is a direct equivalent with identical resistance, tolerance, power rating, package dimensions, and operating temperature range. Both parts are ROHS3 compliant with MSL 1 rating and thick film composition.

Q: What is the advantage of using ERJ-2RKF8873X? A: ERJ-2RKF8873X provides higher power dissipation at 0.1W compared to 0.063W in the primary part, while maintaining all other electrical specifications. This upgrade is beneficial in applications where thermal margin is critical. The part also includes Automotive AEC-Q200 qualification.

Q: Are the automotive-qualified parts (AF0402FR-07887KL, CRCW0402887KFKED, RMCF0402FT887K) interchangeable with the standard RC1005F8873CS? A: Yes, these parts are electrically and mechanically interchangeable. They meet all base specifications for resistance, tolerance, package, and operating temperature. The addition of Automotive AEC-Q200 certification represents enhanced qualification, not a deviation from the base specification.

Q: Does the height difference in AF0402FR-07887KL (0.015" vs 0.016") affect compatibility? A: No. The 0.001" (0.03mm) height difference falls within acceptable mechanical tolerance for 0402 package placement and does not affect circuit board assembly or electrical performance.

Q: What is the significance of anti-sulfur construction in AF0402FR-07887KL? A: Anti-sulfur construction provides additional environmental protection in applications exposed to sulfur-containing atmospheres. This feature does not affect electrical performance or compatibility with standard applications.

Q: Can these parts be used interchangeably in high-temperature applications? A: Yes. All listed parts operate across the identical temperature range of -55°C to 155°C with matching temperature coefficient of ±100ppm/°C.

Q: Is there a difference in moisture sensitivity between these parts? A: No. All parts maintain MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.
