ERJ-S08F1581V Equivalent & Substitute Parts

Part Overview

The ERJ-S08F1581V is a 1.58 kOhm ±1% 0.25W thick film chip resistor in 1206 (3216 Metric) package manufactured by Panasonic Electronic Components. This part features anti-sulfur coating and automotive AEC-Q200 qualification, making it suitable for automotive and harsh environment applications. The part is currently in active production status with 1101 pieces available in stock.

Substitute parts become necessary when the primary part experiences supply constraints, extended lead times, or when design flexibility permits component sourcing from alternative manufacturers while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitute parts for the ERJ-S08F1581V are qualified based on the following criteria:

Electrical Parameters (Must Match):

Resistance value: 1.58 kOhms
Tolerance: ±1%
Power rating: 0.25W (1/4W)
Temperature coefficient: ±100ppm/°C
Operating temperature range: -55°C ~ 155°C

Mechanical Parameters (Must Match):

Package / Case: 1206 (3216 Metric)
Number of terminations: 2
Composition: Thick Film

Compliance Parameters (Must Match):

RoHS3 Compliant
Moisture Sensitivity Level: 1 (Unlimited)

All substitute parts listed meet these core requirements. Variations in physical dimensions (length, width, height) within the 1206 package specification and differences in optional features (anti-sulfur coating, moisture resistance) do not disqualify substitution eligibility.

Frequently Asked Questions (FAQ)

Q: Can ERJ-8ENF1581V be used as a direct replacement for ERJ-S08F1581V? A: Electrically and mechanically, yes. Both parts share identical resistance, tolerance, power rating, package, and operating temperature specifications. However, ERJ-8ENF1581V carries "Not For New Designs" status, making it unsuitable for new product development. Use only for existing production or maintenance.

Q: What is the difference between AEC-Q200 qualified and non-qualified parts? A: AEC-Q200 qualification indicates the part meets automotive industry reliability standards. Parts with this rating (ERJ-S08F1581V, ERJ-8ENF1581V, CRCW12061K58FKEA, RMCF1206FT1K58) are suitable for automotive applications. Non-qualified parts are acceptable for general industrial and consumer applications.

Q: Are there physical dimension differences between substitute parts? A: Minor variations exist within the 1206 package specification. Length ranges from 0.122" to 0.126" (3.10mm to 3.20mm), width from 0.061" to 0.063" (1.55mm to 1.60mm), and height from 0.024" to 0.030" (0.60mm to 0.75mm). These variations remain within standard 1206 package tolerances and do not affect PCB layout compatibility.

Q: Which substitute offers the best stock availability? A: CR1206-FX-1581ELF (Bourns Inc.) provides the highest stock level at 24,614 pieces. For AEC-Q200 qualified alternatives, CRCW12061K58FKEA (Vishay Dale) offers 17,620 pieces.

Q: Do all substitute parts have the same moisture sensitivity level? A: Yes. All listed parts, including the main part ERJ-S08F1581V, carry Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements during storage or assembly.

Q: Is REACH compliance status consistent across all parts? A: REACH status varies. ERJ-S08F1581V, ERJ-8ENF1581V, CR1206-FX-1581ELF, CRCW12061K58FKEA, RC1206FR-071K58L, and RMCF1206FT1K58 are REACH Unaffected. CRG1206F1K58 shows Vendor Undefined status. Verify REACH compliance requirements with your supply chain if applicable to your application.
