Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS2012F7870CS is determined by strict equivalence across the following parameters:

Electrical Equivalence: Resistance value of 787 Ohms, tolerance of ±1%, and power rating of 0.125W (1/8W) must be identical.

Mechanical Equivalence: Package designation 0805 (2012 Metric) with matching physical dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm) and two terminations.

Environmental Equivalence: Temperature coefficient of ±100ppm/°C and operating temperature range of -55°C ~ 155°C must be maintained.

Compliance Equivalence: ROHS3 compliance and Moisture Sensitivity Level 1 (Unlimited) classification required.

All four identified substitute parts meet these criteria. Additional features such as automotive AEC-Q200 certification or anti-sulfur construction represent enhanced specifications that do not disqualify substitution but indicate application-specific suitability.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts are classified as Active product status with ROHS3 compliance and MSL 1 rating, establishing direct functional equivalence to the RCS2012F7870CS.

CRCW0805787RFKEA (Vishay Dale): Automotive AEC-Q200 rated. Lowest seated height at 0.020" (0.50mm). Suitable for applications requiring automotive-grade qualification.

ERJ-6ENF7870V (Panasonic Electronic Components): Automotive AEC-Q200 rated. Highest seated height at 0.028" (0.70mm). Highest inventory availability at 54,236 pieces. Suitable for automotive applications with space constraints less critical.

RC0805FR-07787RL (YAGEO): Moisture-resistant construction matching original anti-sulfur feature set. Seated height 0.024" (0.60mm). Highest inventory availability at 89,266 pieces. Suitable for general industrial applications.

RMCF0805FT787R (Stackpole Electronics Inc): Automotive AEC-Q200 rated. Seated height 0.026" (0.65mm), matching original specification. Suitable for automotive applications requiring dimensional consistency.

Selection between substitute parts depends on application requirements: automotive qualification needs, physical height constraints, and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can CRCW0805787RFKEA replace RCS2012F7870CS in non-automotive applications?

A: Yes. The automotive AEC-Q200 certification represents an enhanced specification. All electrical, mechanical, and compliance parameters are equivalent, enabling substitution in any application where the original part is specified.

Q: What is the significance of the seated height differences among substitute parts?

A: Seated height variations (0.020" to 0.028") reflect manufacturing tolerances within the 0805 package specification. All values remain within acceptable PCB assembly parameters. Height differences are relevant only in applications with strict vertical clearance constraints.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All identified substitute parts carry ROHS3 compliance certification, matching the original RCS2012F7870CS specification.

Q: Does the anti-sulfur feature of RCS2012F7870CS require a substitute with identical construction?

A: No. Anti-sulfur and moisture-resistant features are protective enhancements. All substitute parts maintain MSL 1 (Unlimited) rating, indicating equivalent moisture protection. Substitution is valid without matching the specific anti-sulfur construction method.

Q: Can ERJ-6ENF7870V be used in applications originally designed for RCS2012F7870CS?

A: Yes. Electrical specifications (787 Ohms ±1%, 0.125W), package format (0805), temperature range (-55°C ~ 155°C), and compliance certifications are identical. The 0.028" seated height is within 0805 package tolerance and does not prevent substitution.

Q: What inventory considerations apply when selecting a substitute?

A: RC0805FR-07787RL (YAGEO) offers the highest inventory at 89,266 pieces. ERJ-6ENF7870V (Panasonic) provides 54,236 pieces. Both exceed typical procurement volumes. Selection should prioritize application-specific requirements (automotive qualification, height constraints) over inventory quantity alone.
