Key Parameters

Substitute Part Grouping Explanation

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

Electrical Equivalence: Resistance value (1.96 kOhms), tolerance (±1%), and power rating (0.063W minimum) must match or exceed the main part specification.

Mechanical Compatibility: Package designation (0402/1005 Metric), physical dimensions (0.039" L × 0.020" W / 1.00mm × 0.50mm), seated height (≤0.016" / 0.40mm), and termination count (2) must be identical.

Environmental Compliance: Operating temperature range (-55°C to 155°C), temperature coefficient (±100ppm/°C), RoHS3 compliance, and MSL Level 1 rating are mandatory.

Composition: Thick film construction is required for all substitutes.

Substitute parts are categorized as follows:

Direct Substitutes: Identical electrical, mechanical, and environmental specifications with no functional differences.

Upgrade Substitutes: Higher power rating (0.1W vs. 0.063W) with automotive AEC-Q200 qualification, suitable for applications requiring enhanced thermal margin or automotive-grade reliability.

Similar Substitutes: Automotive AEC-Q200 qualified variants or alternative manufacturer series meeting all core electrical and mechanical parameters.

Engineering Selection Recommendations

Direct Substitution (No Application Constraints):

CR0402-FX-1961GLF (Bourns Inc.) and RC0402FR-071K96L (YAGEO) are direct electrical and mechanical equivalents to RC1005F1961CS. Both maintain identical power rating (0.063W), package dimensions, and environmental specifications. RC0402FR-071K96L offers significantly higher inventory availability (502,294 pcs) compared to the main part (1,116 pcs), providing superior supply chain access.

Upgrade Selection (Enhanced Reliability Margin):

ERJ-2RKF1961X (Panasonic Electronic Components) provides a 0.1W power rating versus the 0.063W specification of the main part, delivering 58% additional thermal headroom. This variant includes automotive AEC-Q200 qualification and is suitable for applications requiring enhanced reliability or operating in thermally constrained environments.

Automotive-Grade Alternatives:

AC0402FR-071K96L (YAGEO), CRCW04021K96FKED (Vishay Dale), and RMCF0402FT1K96 (Stackpole Electronics Inc) are automotive AEC-Q200 qualified variants maintaining the 0.063W power rating and full electrical equivalence. These components are appropriate for automotive, industrial, or mission-critical applications requiring automotive-grade component qualification. RMCF0402FT1K96 offers the highest inventory level (179,581 pcs) among automotive-qualified options.

All substitute parts maintain ROHS3 compliance, MSL Level 1 rating, and identical operating temperature range (-55°C to 155°C).

Frequently Asked Questions (FAQ)

Q: Can CR0402-FX-1961GLF replace RC1005F1961CS in any application?

A: CR0402-FX-1961GLF is a direct electrical and mechanical equivalent. Both components share identical resistance (1.96 kOhms), tolerance (±1%), power rating (0.063W), package (0402), and operating temperature range (-55°C to 155°C). Substitution is valid for all applications where RC1005F1961CS is specified, with no functional or performance differences.

Q: What is the difference between the 0.063W and 0.1W power ratings?

A: Power rating indicates maximum continuous power dissipation capability. ERJ-2RKF1961X (0.1W) can safely dissipate 58% more power than RC1005F1961CS (0.063W) while maintaining specified operating temperature limits. In applications where actual power dissipation is below 0.063W, both ratings are functionally equivalent. The higher rating provides additional thermal margin and is beneficial in high-temperature or high-current environments.

Q: Are automotive AEC-Q200 qualified parts suitable for non-automotive applications?

A: Automotive AEC-Q200 qualification indicates enhanced reliability testing and quality assurance beyond standard commercial specifications. These parts (AC0402FR-071K96L, CRCW04021K96FKED, RMCF0402FT1K96) are fully compatible with non-automotive applications and offer equivalent or superior performance to non-qualified variants. Their use in non-automotive designs provides additional reliability margin without penalty.

Q: Does the absence of "Moisture Resistant" designation in CR0402-FX-1961GLF affect compatibility?

A: CR0402-FX-1961GLF maintains MSL Level 1 (Unlimited) rating identical to RC1005F1961CS, indicating no moisture sensitivity limitations. The absence of explicit "Moisture Resistant" feature designation does not indicate reduced moisture performance; both components are suitable for applications with standard moisture exposure conditions.

Q: Which substitute offers the best supply chain availability?

A: RC0402FR-071K96L (YAGEO) provides the highest inventory level at 502,294 pcs, followed by RMCF0402FT1K96 (Stackpole Electronics Inc) at 179,581 pcs. For automotive-qualified variants, RMCF0402FT1K96 offers superior availability. Selection should balance inventory depth with application-specific requirements (automotive qualification, power rating, feature set).

Q: Are all substitute parts packaged in Tape & Reel format?

A: All listed substitute parts are supplied in Tape & Reel (TR) packaging, matching the main part specification. This format is standard for high-volume SMD component distribution and is compatible with automated assembly equipment.
