Frequently Asked Questions (FAQ)

Q: Can ERJ-12SF7871U be used in new designs? A: No. ERJ-12SF7871U carries "Not For New Designs" status. Use ERJ-S1DF7871U or RMCF2010FT7K87 for new product development.

Q: Are all substitute parts mechanically compatible? A: Yes. All parts use the 2010 (5025 Metric) package with identical dimensions: 0.197" L x 0.098" W (5.00mm x 2.50mm) and maximum seated height of 0.028" (0.70mm).

Q: Do substitute parts meet automotive requirements? A: Yes. All listed parts carry AEC-Q200 automotive qualification and operate across -55°C ~ 155°C with ±100ppm/°C temperature coefficient.

Q: What is the difference between ERJ-S1DF7871U and ERJ-12SF7871U? A: Both are Panasonic thick film 2010 resistors with identical electrical specifications. The primary difference is product status: ERJ-S1DF7871U is active for new designs, while ERJ-12SF7871U is legacy (not for new designs). ERJ-S1DF7871U includes anti-sulfur coating.

Q: Are all parts RoHS compliant? A: Yes. All substitute parts are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity level).

Q: Can RMCF2010FT7K87 replace ERJ-S1DF7871U directly? A: Yes. RMCF2010FT7K87 is a direct electrical and mechanical equivalent from Stackpole Electronics Inc with active production status.
