ERJ-S08F1871V 1.87kΩ 1206 Chip Resistor Equivalent & Substitute Parts

Part Overview

The ERJ-S08F1871V is a 1.87 kOhms ±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 automotive and industrial applications requiring high reliability in harsh environments. The product is currently active and available in high volume (901 pcs in stock).

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when design requirements shift between automotive and general-purpose applications, or when supply chain optimization requires sourcing from multiple qualified manufacturers while maintaining identical electrical and mechanical performance.

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S08F1871V is determined by strict equivalence across the following critical parameters:

Resistance Value: 1.87 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)
Environmental Compliance: ROHS3 Compliant, MSL 1 (exact match required)

All substitute parts listed below meet these criteria. Variations in secondary features (such as anti-sulfur coating presence, automotive AEC-Q200 rating, or specific dimensional tolerances within the 1206 package) do not disqualify substitution but may require design review based on application requirements.

Engineering Selection Recommendations

Primary Selection (New Designs): CRCW12061K87FKEA (Vishay Dale), RMCF1206FT1K87 (Stackpole Electronics Inc), or RC1206FR-071K87L (YAGEO). All three are active products with confirmed ROHS3 compliance and MSL 1 rating. Vishay Dale and Stackpole Electronics Inc parts carry automotive AEC-Q200 qualification, matching the primary part's automotive-grade specification.

Secondary Selection (Existing Designs): ERJ-8ENF1871V (Panasonic Electronic Components) is electrically and mechanically equivalent but marked "Not For New Designs." This part is suitable only for sustaining production of existing designs or as a temporary substitute when primary options are unavailable. High inventory availability (52,237 pcs) may support extended lead-time mitigation.

Application-Specific Considerations: For automotive applications requiring AEC-Q200 qualification, select RMCF1206FT1K87 or CRCW12061K87FKEA. For general industrial applications without automotive requirements, RC1206FR-071K87L (YAGEO) provides equivalent performance with moisture-resistant thick film composition.

Frequently Asked Questions (FAQ)

Q: Can ERJ-8ENF1871V be used as a direct replacement for ERJ-S08F1871V?

A: Yes, ERJ-8ENF1871V is electrically and mechanically equivalent. However, it is marked "Not For New Designs." Use only for sustaining production of existing designs or temporary supply chain solutions.

Q: What is the difference between the automotive-qualified parts (RMCF1206FT1K87, CRCW12061K87FKEA) and the general-purpose part (RC1206FR-071K87L)?

A: RMCF1206FT1K87 and CRCW12061K87FKEA carry AEC-Q200 automotive qualification. RC1206FR-071K87L is qualified for general industrial use with moisture-resistant composition. All three meet identical electrical specifications (1.87 kΩ ±1%, 0.25W, ±100ppm/°C, -55°C ~ 155°C). Selection depends on application requirements.

Q: Are there dimensional differences between substitute parts?

A: All parts use the 1206 (3216 Metric) package. Minor variations exist in maximum seated height: ERJ-S08F1871V and RMCF1206FT1K87 are 0.028" (0.70mm), CRCW12061K87FKEA is 0.024" (0.60mm), and RC1206FR-071K87L is 0.026" (0.65mm). These variations are within standard 1206 package tolerances and do not affect PCB layout or assembly compatibility.

Q: Do all substitute parts have the same anti-sulfur or moisture-resistant properties?

A: No. ERJ-S08F1871V features anti-sulfur coating. RC1206FR-071K87L features moisture-resistant composition. RMCF1206FT1K87 and CRCW12061K87FKEA do not specify these secondary features in the provided data. For applications requiring specific environmental protection, verify coating or composition requirements against design specifications.

Q: What is the inventory status of each substitute part?

A: ERJ-S08F1871V: 901 pcs; ERJ-8ENF1871V: 52,237 pcs; CRCW12061K87FKEA: 23,051 pcs; RC1206FR-071K87L: 82,579 pcs; RMCF1206FT1K87: 9,839 pcs. All parts are available as new original stock.
