ERJ-S08F4993V Equivalent & Substitute Parts

Part Overview

The ERJ-S08F4993V is a 499 kOhms ±1% 0.25W (1/4W) 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 high-reliability applications in automotive and industrial environments. The part is currently in active production status with 1007 units in stock.

Substitute parts become necessary when the primary part faces supply constraints, extended lead times, or when design requirements allow for functionally equivalent alternatives from different manufacturers. All substitute parts listed maintain identical electrical specifications and package dimensions within acceptable tolerances.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict adherence to the following parameters:

Resistance Value: Must be 499 kOhms
Tolerance: Must be ±1%
Power Rating: Must be 0.25W (1/4W) or higher
Package: Must be 1206 (3216 Metric)
Composition: Must be Thick Film
Temperature Coefficient: Must be ±100ppm/°C
Operating Temperature: Must support -55°C ~ 155°C range
Terminations: Must have 2 terminations
RoHS Compliance: Must be ROHS3 Compliant

All listed substitute parts meet these criteria. Parts with higher power ratings (0.75W) are included as they are backward compatible with 0.25W applications. Variations in physical dimensions (length, width, height) within the 1206 package specification are acceptable as they remain within standard PCB footprint tolerances.

Engineering Selection Recommendations

Primary Substitutes (Recommended for New Designs)

Parts with Active product status and ROHS3 compliance are suitable for new design implementations: AC1206FR-07499KL, AF1206FR-07499KL, CHV1206-FX-4993ELF, CR1206-FX-4993ELF, CRCW1206499KFKEA, RC1206FR-07499KL, and RMCF1206FG499K. These parts maintain full compliance with current environmental and automotive standards.

Secondary Substitutes (Existing Designs Only)

ERJ-8ENF4993V carries "Not For New Designs" status and should be used only in existing production or maintenance scenarios where design continuity is required.

Non-Compliant Parts

CRCW1206499KFKTA is RoHS non-compliant and REACH Affected. This part is not suitable for applications requiring RoHS3 compliance and should be avoided in new designs or regulated markets.

Higher Power Rating Option

CRCW1206499KFKEAHP provides 0.75W power rating with pulse withstanding capability. This part is electrically and mechanically compatible with 0.25W applications and offers enhanced thermal margin for demanding environments.

Frequently Asked Questions (FAQ)

Q: Can I substitute ERJ-S08F4993V with any of the listed parts?

A: Yes, all parts listed except CRCW1206499KFKTA are direct substitutes. CRCW1206499KFKTA lacks RoHS3 compliance and should not be used in regulated applications. ERJ-8ENF4993V is marked "Not For New Designs" and should only be used in existing production.

Q: What is the difference between the Panasonic ERJ-S08F4993V and ERJ-8ENF4993V?

A: Both parts have identical electrical specifications (499 kOhms ±1%, 0.25W, 1206 package). The primary difference is product status: ERJ-S08F4993V is Active, while ERJ-8ENF4993V is Not For New Designs. The ERJ-8EN series is an older generation.

Q: Are there any feature differences between manufacturers?

A: Feature variations exist but do not affect substitution eligibility. ERJ-S08F4993V includes anti-sulfur coating. AC1206FR-07499KL and RC1206FR-07499KL feature moisture resistance. CHV1206-FX-4993ELF is specified for high voltage applications. AF1206FR-07499KL includes anti-sulfur coating. These features are additive and do not prevent substitution.

Q: Can I use CRCW1206499KFKEAHP (0.75W) instead of the 0.25W rated part?

A: Yes. The 0.75W part is backward compatible with 0.25W applications. Higher power rating provides additional thermal margin and is electrically equivalent for the same resistance and tolerance values.

Q: What packaging formats are available?

A: The main part ERJ-S08F4993V is supplied in Tape & Reel (TR) format. Substitute parts are available in Tape & Reel (TR) or Cut Tape (CT) & Digi-Reel formats. Packaging format does not affect electrical or mechanical compatibility.

Q: Are all listed parts AEC-Q200 qualified?

A: Most parts carry AEC-Q200 automotive qualification. CHV1206-FX-4993ELF and RC1206FR-07499KL do not list AEC-Q200 ratings. For automotive applications requiring AEC-Q200 compliance, select from: ERJ-S08F4993V, ERJ-8ENF4993V, AC1206FR-07499KL, AF1206FR-07499KL, CR1206-FX-4993ELF, CRCW1206499KFKEA, CRCW1206499KFKEAHP, CRCW1206499KFKTA, or RMCF1206FG499K.

Q: What is the inventory status for these parts?

A: RC1206FR-07499KL has the highest inventory (1,484,497 units). CRCW1206499KFKEA (73,824 units) and CR1206-FX-4993ELF (71,545 units) also have substantial stock. ERJ-S08F4993V has 1,007 units available. Inventory levels should be confirmed with suppliers for current availability.
