ERJ-S08F1021V Equivalent & Substitute Parts

Part Overview

The ERJ-S08F1021V is a 1.02 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 799 units in stock.

Substitute parts become necessary when the primary part faces supply constraints, extended lead times, or when design flexibility permits equivalent alternatives from qualified 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 equivalence across the following critical parameters:

Resistance value: 1.02 kOhms
Tolerance: ±1%
Power rating: 0.25W (1/4W)
Package: 1206 (3216 Metric)
Composition: Thick Film
Temperature coefficient: ±100ppm/°C
Operating temperature range: -55°C ~ 155°C
Moisture sensitivity level: 1 (Unlimited)
RoHS compliance: ROHS3 Compliant

All listed substitute parts meet these criteria. Dimensional variations within the 1206 package specification (length 0.122" to 0.126", height 0.024" to 0.028") remain within acceptable PCB assembly tolerances. Automotive AEC-Q200 qualification is present on the main part and most substitutes, providing additional assurance for mission-critical applications.

Engineering Selection Recommendations

For new designs, prioritize parts with Active product status: AC1206FR-071K02L (YAGEO), CRCW12061K02FKEA (Vishay Dale), RC1206FR-071K02L (YAGEO), and RMCF1206FT1K02 (Stackpole Electronics Inc). All maintain ROHS3 compliance and unlimited moisture sensitivity rating.

For automotive and mission-critical applications requiring AEC-Q200 qualification, select from: AC1206FR-071K02L, CRCW12061K02FKEA, RMCF1206FT1K02, or the primary part ERJ-S08F1021V. The ERJ-8ENF1021V carries "Not For New Designs" status and should be used only for legacy system maintenance or repair.

RC1206FR-071K02L lacks AEC-Q200 rating but remains suitable for non-automotive applications where moisture resistance is the primary requirement.

Frequently Asked Questions (FAQ)

Q: Can ERJ-8ENF1021V replace ERJ-S08F1021V in new designs?

A: ERJ-8ENF1021V is marked "Not For New Designs" and should not be used in new applications. It is suitable only for legacy system maintenance or repair where the original part is unavailable.

Q: What is the difference between AC1206FR-071K02L and RC1206FR-071K02L?

A: AC1206FR-071K02L includes AEC-Q200 automotive qualification and moisture-resistant features. RC1206FR-071K02L provides moisture resistance only without automotive qualification. Both are electrically equivalent at 1.02 kOhms ±1%.

Q: Are all substitute parts compatible with the same PCB footprint?

A: Yes. All parts use the 1206 (3216 Metric) package. Dimensional variations (length 0.122" to 0.126", height 0.024" to 0.028") fall within standard PCB assembly tolerances and do not require footprint modification.

Q: Which substitute offers the best availability?

A: RC1206FR-071K02L has the highest inventory at 65,740 units. For AEC-Q200 qualified alternatives, CRCW12061K02FKEA offers 15,505 units in stock.

Q: Is RoHS3 compliance maintained across all substitutes?

A: Yes. All listed parts are ROHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Q: Can RC1206FR-071K02L be used in automotive applications?

A: RC1206FR-071K02L lacks AEC-Q200 qualification and is not recommended for automotive applications. Use AC1206FR-071K02L, CRCW12061K02FKEA, or RMCF1206FT1K02 for automotive requirements.
