ERJ-S08F1740V Equivalent & Substitute Parts

Part Overview

The ERJ-S08F1740V is a 174 Ohm ±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, designed for high-reliability applications in automotive and industrial environments. The part is currently active in production with 887 units in stock.

Substitute parts become necessary when the primary part reaches end-of-life status, experiences supply constraints, or when design flexibility is required across multiple qualified suppliers while maintaining identical electrical and mechanical performance.

Substitute Part Grouping Explanation

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

Resistance value: 174 Ohms (exact match required)
Tolerance: ±1% (exact match required)
Power rating: 0.25W (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 to 155°C (exact match required)
RoHS compliance: ROHS3 Compliant (exact match required)
Moisture sensitivity: MSL 1 (exact match required)

All five substitute parts listed meet these criteria. Variations in physical dimensions (length, width, height) within the 1206 package specification and differences in specific feature sets (anti-sulfur coating, moisture resistance) do not affect functional substitutability for this resistance value and power rating.

Engineering Selection Recommendations

For new designs and active production, select from parts with Active product status: AC1206FR-07174RL (YAGEO), CRCW1206174RFKEA (Vishay Dale), RC1206FR-07174RL (YAGEO), or RMCF1206FT174R (Stackpole Electronics). All four maintain full AEC-Q200 automotive qualification and ROHS3 compliance.

The ERJ-8ENF1740V carries "Not For New Designs" status and should be used only for legacy system maintenance or when existing inventory must be consumed in ongoing production runs.

For automotive applications requiring AEC-Q200 certification, all recommended substitutes except RC1206FR-07174RL explicitly carry this rating. RC1206FR-07174RL remains functionally equivalent but lacks explicit AEC-Q200 designation in its specification.

Frequently Asked Questions (FAQ)

Q: Can ERJ-S08F1740V be directly replaced with ERJ-8ENF1740V?

A: Yes, electrical and mechanical parameters are identical. However, ERJ-8ENF1740V is marked "Not For New Designs," limiting its use to legacy applications or inventory management scenarios.

Q: Are all substitute parts suitable for automotive applications?

A: Five of six substitutes carry AEC-Q200 qualification (ERJ-8ENF1740V, AC1206FR-07174RL, CRCW1206174RFKEA, RMCF1206FT174R). RC1206FR-07174RL does not list AEC-Q200 in its specification, though it meets all other electrical and mechanical requirements.

Q: Do physical dimension variations affect substitutability?

A: No. All parts conform to the 1206 (3216 Metric) package specification. Minor variations in seated height (0.024" to 0.028") and length (0.122" to 0.126") remain within package tolerance and do not affect circuit performance or PCB layout compatibility.

Q: Which substitute offers the highest inventory availability?

A: RC1206FR-07174RL has 174,012 units in stock, followed by ERJ-8ENF1740V with 75,975 units. AC1206FR-07174RL has 14,274 units, CRCW1206174RFKEA has 24,159 units, and RMCF1206FT174R has 10,784 units.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All listed parts meet ROHS3 compliance requirements and carry MSL 1 (Unlimited) moisture sensitivity rating.
