Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS2012F19R1CS is determined by strict equivalence across the following critical parameters:

Electrical Specifications: Resistance value (19.1 Ohms), tolerance (±1%), and power rating (0.125W) must be identical. Temperature coefficient (±100ppm/°C) and operating temperature range (-55°C ~ 155°C) establish thermal performance boundaries.

Mechanical Compatibility: Package type (0805 / 2012 Metric), physical dimensions (0.079" L x 0.049" W), and number of terminations (2) ensure PCB footprint compatibility and assembly process alignment.

Regulatory Compliance: RoHS3 compliance and Moisture Sensitivity Level 1 (Unlimited) are mandatory for direct substitution. REACH status and ECCN classification must match or exceed the original specification.

Composition and Construction: Thick film composition is required. Functional features (anti-sulfur, moisture resistant, or automotive AEC-Q200 qualification) may vary without affecting electrical or mechanical substitution validity.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts—CRCW080519R1FKEA (Vishay Dale), ERJ-6ENF19R1V (Panasonic), and RC0805FR-0719R1L (YAGEO)—meet the electrical and mechanical requirements for direct substitution with the RCS2012F19R1CS.

CRCW080519R1FKEA carries AEC-Q200 automotive qualification and features the lowest seated height (0.020" / 0.50mm), making it suitable for space-constrained applications and automotive-grade designs.

ERJ-6ENF19R1V also carries AEC-Q200 automotive qualification with a seated height of 0.028" (0.70mm), appropriate for automotive and industrial applications requiring enhanced reliability standards.

RC0805FR-0719R1L provides moisture-resistant characteristics similar to the original RCS2012F19R1CS, with a seated height of 0.024" (0.60mm), suitable for general-purpose and consumer applications.

All parts maintain ROHS3 compliance, MSL Level 1 (Unlimited), and identical electrical performance across the specified operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can CRCW080519R1FKEA replace RCS2012F19R1CS in any application?

A: CRCW080519R1FKEA meets all electrical and mechanical substitution criteria. The AEC-Q200 automotive qualification is an additional feature that does not prevent use in non-automotive applications. The lower seated height (0.020" vs 0.026") is compatible with standard 0805 PCB layouts.

Q: What is the difference between the three substitute parts?

A: All three substitutes provide identical electrical performance (19.1 Ohms ±1%, 0.125W, ±100ppm/°C). Differences exist in seated height and feature set: CRCW080519R1FKEA and ERJ-6ENF19R1V include AEC-Q200 automotive qualification, while RC0805FR-0719R1L emphasizes moisture resistance. Seated heights range from 0.020" to 0.028", all compatible with standard 0805 footprints.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts and the original RCS2012F19R1CS are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), meeting current regulatory requirements.

Q: Does package compatibility guarantee mechanical interchangeability?

A: Yes. All parts use the 0805 (2012 Metric) package with identical footprint dimensions (0.079" L x 0.049" W). Seated height variations (0.020" to 0.028") fall within standard PCB assembly tolerances and do not affect mechanical interchangeability.

Q: Which substitute part should be selected for automotive applications?

A: CRCW080519R1FKEA and ERJ-6ENF19R1V both carry AEC-Q200 automotive qualification. Selection between these two depends on specific height constraints and supplier availability.
