Equivalent & Substitute Parts for ERJ-S14F7871U

Part Overview

The ERJ-S14F7871U is a 7.87 kOhms ±1% thick film chip resistor manufactured by Panasonic Electronic Components in the 1210 (3225 Metric) package format. This component is rated for 0.5W power dissipation and meets AEC-Q200 automotive qualification standards with anti-sulfur protection. The part is currently in active production status with 996 units available in stock.

Equivalent and substitute parts become necessary when the primary part experiences supply constraints, extended lead times, or when design flexibility permits the use of functionally compatible alternatives from different manufacturers or product series.

Engineering Selection Recommendations

Primary Selection: ERJ-S14F7871U

The ERJ-S14F7871U maintains active product status with anti-sulfur protection and represents the current generation Panasonic offering. This part is recommended for new designs requiring maximum long-term availability and manufacturer support.

Secondary Selection: CRCW12107K87FKEA

The CRCW12107K87FKEA from Vishay Dale is an active product that provides full electrical and mechanical equivalence. This substitute is suitable when Panasonic supply is constrained. The seated height is 0.024" (0.60mm) compared to 0.028" (0.70mm) for the primary part; this difference is within standard PCB design tolerances for 1210 packages and does not affect circuit functionality.

Tertiary Selection: ERJ-14NF7871U

The ERJ-14NF7871U is a Panasonic product marked as "Not For New Designs." This part is electrically and mechanically equivalent but should be used only for legacy system maintenance or repair applications where supply of the primary part is unavailable and design revision is not feasible.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF7871U be used in new product designs?

A: No. The ERJ-14NF7871U carries a "Not For New Designs" status. New designs must use either the ERJ-S14F7871U or CRCW12107K87FKEA. The ERJ-14NF7871U is restricted to legacy system support and repair applications.

Q: What is the significance of the height difference between CRCW12107K87FKEA (0.024") and ERJ-S14F7871U (0.028")?

A: Both parts conform to the 1210 (3225 Metric) package specification. The 0.004" (0.10mm) height variation falls within standard package tolerances and does not affect PCB layout, reflow soldering, or circuit performance. Both parts are mechanically interchangeable on standard 1210 footprints.

Q: Are all substitute parts AEC-Q200 qualified?

A: Yes. All listed substitute parts carry AEC-Q200 automotive qualification. This certification is maintained across all equivalent options.

Q: Do all substitute parts have the same RoHS and REACH compliance status?

A: Yes. All substitute parts are ROHS3 Compliant and REACH Unaffected, matching the primary part's compliance profile.

Q: Can CRCW12107K87FKEA be used as a direct drop-in replacement?

A: Yes. The CRCW12107K87FKEA is a direct drop-in replacement. All electrical parameters, package dimensions, and certifications are equivalent. The minor height difference does not affect PCB assembly or functionality.

Q: What is the MSL rating and why does it matter?

A: All parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. These parts do not require special moisture control during storage, handling, or assembly, simplifying supply chain management.
