Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS2012F1962CS is determined by strict equivalence across the following critical parameters:

Electrical Specifications: Resistance value (19.6 kOhms), tolerance (±1%), and power rating (0.125W) must match exactly. Temperature coefficient (±100ppm/°C) and operating temperature range (-55°C ~ 155°C) establish thermal performance boundaries.

Mechanical Compatibility: Package designation (0805 / 2012 Metric) and number of terminations (2) ensure physical and electrical interface compatibility with printed circuit boards designed for the main part.

Environmental & Regulatory Compliance: RoHS3 compliance and MSL rating (1 - Unlimited) confirm suitability for standard manufacturing and storage conditions.

All identified substitute parts meet these criteria. Product status (Active vs. Obsolete) and specific feature sets (anti-sulfur, moisture resistant, automotive AEC-Q200 certification) are noted for application-specific selection but do not disqualify substitution based on core electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

Active Production Parts: AC0805FR-0719K6L (YAGEO), CRCW080519K6FKEA (Vishay Dale), ERJ-6ENF1962V (Panasonic Electronic Components), and RC0805FR-0719K6L (YAGEO) are all currently in active production status with full RoHS3 compliance and MSL rating 1. These parts are suitable for new designs and ongoing production requirements.

Automotive Applications: AC0805FR-0719K6L, CRCW080519K6FKEA, and ERJ-6ENF1962V carry AEC-Q200 automotive qualification. Selection of these parts is appropriate for automotive-grade circuit applications.

Obsolete Status: TRR10EZPF1962 (Rohm Semiconductor) is marked as obsolete. While electrically and mechanically equivalent, this part should be used only for legacy system maintenance or repair where new production alternatives are unavailable.

Height Considerations: All substitute parts maintain 0805 package compliance with seated heights ranging from 0.50mm to 0.70mm. CRCW080519K6FKEA offers the lowest profile (0.50mm), while ERJ-6ENF1962V has the highest (0.70mm). Height selection depends on specific PCB layout constraints.

Frequently Asked Questions (FAQ)

Q: Can all listed substitute parts replace the RCS2012F1962CS directly on a PCB?

A: Yes. All substitute parts match the critical electrical specifications (19.6 kΩ ±1%, 0.125W), temperature characteristics (±100ppm/°C, -55°C ~ 155°C), and mechanical package (0805 / 2012 Metric with 2 terminations). Direct PCB replacement is supported without circuit redesign.

Q: What is the difference between anti-sulfur and moisture-resistant features?

A: Anti-sulfur protection prevents corrosion from sulfur-containing atmospheric compounds, while moisture-resistant construction protects against humidity ingress. The RCS2012F1962CS includes both features. Substitute parts specify either or both features. All listed substitutes include at least moisture-resistant properties, meeting the environmental protection requirements of the original part.

Q: Why is TRR10EZPF1962 listed as obsolete?

A: TRR10EZPF1962 is no longer in active production by Rohm Semiconductor. While electrically and mechanically equivalent, it should be selected only when new production alternatives are unavailable or for legacy system support. Active alternatives (YAGEO, Vishay Dale, Panasonic) are recommended for new designs.

Q: Are automotive-qualified parts (AEC-Q200) necessary for all applications?

A: AEC-Q200 qualification is required only for automotive applications subject to automotive industry standards. AC0805FR-0719K6L, CRCW080519K6FKEA, and ERJ-6ENF1962V carry this certification. For non-automotive applications, all active production parts are suitable.

Q: What is the significance of MSL rating 1?

A: MSL (Moisture Sensitivity Level) 1 indicates unlimited shelf life and storage without moisture baking requirements. All listed parts carry MSL 1, confirming compatibility with standard component storage and handling procedures.

Q: Do height differences between substitute parts affect PCB assembly?

A: Height variations (0.50mm to 0.70mm) are within standard 0805 package tolerances and do not affect PCB assembly processes. Selection should be based on specific PCB layout requirements and available clearance above the component.
