ERJ-S08F6191V Equivalent & Substitute Parts

Part Overview

The ERJ-S08F6191V is a 6.19 kOhms ±1% 0.25W chip resistor in 1206 (3216 Metric) package manufactured by Panasonic Electronic Components. This thick film resistor features anti-sulfur coating and automotive AEC-Q200 qualification, designed for applications requiring high reliability in harsh environments. The part is currently in active production status with 656 units in stock.

Substitute parts become necessary when the primary part faces supply constraints, extended lead times, or when design flexibility permits equivalent alternatives that meet identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S08F6191V is determined by strict equivalence across the following critical parameters:

Resistance value: 6.19 kOhms (exact match required)
Tolerance: ±1% (exact match required)
Power rating: 0.25W / 1/4W (exact match required)
Package: 1206 (3216 Metric) (exact match required)
Composition: Thick Film (exact match required)
Temperature coefficient: ±100ppm/°C (exact match required)
Operating temperature range: -55°C ~ 155°C (exact match required)
Termination count: 2 (exact match required)
RoHS compliance: ROHS3 Compliant (exact match required)
MSL rating: 1 (Unlimited) (exact match required)

All five substitute parts listed meet these criteria and are therefore direct functional equivalents. Variations in physical dimensions (length, width, height) and manufacturer-specific features (anti-sulfur vs. moisture resistant coatings) do not affect electrical performance or circuit compatibility.

Engineering Selection Recommendations

For automotive and high-reliability applications: CRCW12066K19FKEA (Vishay Dale) and RMCF1206FT6K19 (Stackpole Electronics Inc) are preferred substitutes. Both maintain active production status and carry AEC-Q200 automotive qualification identical to the primary part.

For general-purpose applications: CR1206-FX-6191ELF (Bourns Inc.) and RC1206FR-076K19L (YAGEO) are functionally equivalent alternatives. Both are in active production and meet all electrical and mechanical specifications, though they lack automotive qualification.

Avoid: ERJ-8ENF6191V (Panasonic Electronic Components) is marked "Not For New Designs" and should only be used for legacy system maintenance or repair applications where supply of the primary part is unavailable.

Frequently Asked Questions (FAQ)

Q: Can I substitute ERJ-S08F6191V with any of these parts in my circuit?

A: Yes. All listed substitutes meet identical electrical specifications (6.19 kΩ ±1%, 0.25W, ±100ppm/°C, -55°C to 155°C) and are packaged in the same 1206 form factor. They are pin-compatible and functionally interchangeable at the circuit level.

Q: What is the difference between parts with and without AEC-Q200 qualification?

A: AEC-Q200 certification indicates the part has passed automotive-grade reliability testing and is suitable for automotive applications. Parts without this rating are suitable for general industrial and consumer applications but should not be used in automotive designs unless explicitly approved by your design authority.

Q: Why is ERJ-8ENF6191V marked "Not For New Designs"?

A: This designation indicates the manufacturer is phasing out this part number in favor of newer alternatives. It remains available for existing designs and repairs but should not be selected for new product development.

Q: Are there physical dimension differences between these parts?

A: Minor variations exist in length, width, and height within the 1206 package specification. All parts fit within standard 1206 footprints and are compatible with existing PCB layouts. Specific dimension requirements should be verified against your PCB design if space constraints are critical.

Q: Do all these parts have the same moisture sensitivity level?

A: Yes. All listed parts carry MSL rating 1 (Unlimited), indicating they can be stored indefinitely without moisture baking requirements and are suitable for standard manufacturing processes.
