Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1005F2372CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 23.7 kOhms
• Tolerance: ±1%
• Package / Case: 0402 (1005 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100 ppm/°C
• Operating Temperature Range: -55°C to 155°C
• Number of Terminations: 2
• Moisture Sensitivity Level: 1 (Unlimited)
• RoHS Status: ROHS3 Compliant

Allowable Variation:

• Power rating: 0.063W (1/16W) or higher
• Features: Additional certifications (AEC-Q200, moisture resistance) do not disqualify substitution

All substitute parts listed below meet or exceed these parameters and are qualified for direct replacement in applications requiring the RC1005F2372CS electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (Identical Specifications):

CR0402-FX-2372GLF (Bourns Inc.) and RC0402FR-0723K7L (YAGEO) are direct functional equivalents to the RC1005F2372CS. Both maintain identical electrical parameters, package format, and compliance certifications. Selection between these options depends on packaging preference (CR0402-FX-2372GLF supplied in Tape & Reel; RC0402FR-0723K7L available in Cut Tape & Digi-Reel) and inventory availability.

Upgraded Alternative:

ERJ-2RKF2372X (Panasonic Electronic Components) provides higher power rating (0.1W versus 0.063W) while maintaining all other electrical specifications. This part qualifies as an upgrade option for applications where thermal margin improvement is beneficial. Automotive AEC-Q200 certification provides additional reliability assurance for demanding environments.

Enhanced Alternatives with Automotive Qualification:

AC0402FR-0723K7L (YAGEO), CRCW040223K7FKED (Vishay Dale), and RMCF0402FT23K7 (Stackpole Electronics Inc) all incorporate Automotive AEC-Q200 certification alongside identical electrical specifications to the main part. These options are suitable for applications requiring automotive-grade component qualification or enhanced reliability documentation. AC0402FR-0723K7L additionally includes moisture-resistant features matching the original part.

All listed substitutes maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard PCB assembly processes and storage conditions.

Frequently Asked Questions (FAQ)

Q: Can ERJ-2RKF2372X replace RC1005F2372CS in all applications?

A: Yes. ERJ-2RKF2372X meets all mandatory electrical parameters and exceeds the power rating (0.1W versus 0.063W). The higher power rating does not create incompatibility; it provides additional thermal margin. The component occupies identical physical space (0402 package) and operates within the same temperature range.

Q: What is the difference between "Direct," "Upgrade," and "Similar" substitute classifications?

A: Direct substitutes match all electrical and mechanical specifications exactly. Upgrade substitutes provide enhanced performance (higher power rating) while maintaining compatibility. Similar substitutes add certifications (AEC-Q200) or features (moisture resistance) beyond the base specification without compromising compatibility.

Q: Are packaging differences between Cut Tape and Tape & Reel significant for substitution?

A: Packaging format affects supply chain logistics and assembly line integration but does not impact electrical or mechanical compatibility. CR0402-FX-2372GLF (Tape & Reel) and RC0402FR-0723K7L (Cut Tape & Digi-Reel) are functionally interchangeable; selection depends on manufacturing process requirements and inventory management practices.

Q: Does Automotive AEC-Q200 certification affect compatibility with non-automotive applications?

A: No. AEC-Q200 certification indicates enhanced qualification testing and reliability documentation. Parts carrying this certification (AC0402FR-0723K7L, CRCW040223K7FKED, RMCF0402FT23K7) are fully compatible with standard industrial and consumer applications. The certification represents additional qualification, not a restriction.

Q: Can I substitute RC1005F2372CS with a part having different moisture sensitivity level?

A: All listed substitutes maintain MSL 1 (Unlimited) rating, matching the original part. Substitution with parts having higher MSL ratings (2, 3, etc.) would introduce moisture sensitivity constraints and is not recommended without design review.

Q: What parameters must remain identical for substitution to be valid?

A: Resistance value (23.7 kOhms), tolerance (±1%), package format (0402), composition (thick film), temperature coefficient (±100 ppm/°C), operating temperature range (-55°C to 155°C), and termination count (2) must remain unchanged. Power rating may increase; additional certifications do not disqualify substitution.
