Engineering Selection Recommendations

All substitute parts meet the core electrical and mechanical specifications of the RMCS1206FT191R. Selection should be based on product status and application requirements:

CRCW1206191RFKEA (Vishay Dale) and RC1206FR-07191RL (YAGEO) are both classified as Active products and are suitable for new designs. CRCW1206191RFKEA includes AEC-Q200 automotive qualification, making it appropriate for automotive applications. RC1206FR-07191RL features moisture-resistant construction.

ERJ-8ENF1910V (Panasonic) is classified as Not For New Designs and should be used only in legacy system maintenance or replacement scenarios where original part continuity is required.

Frequently Asked Questions (FAQ)

Q: Can CRCW1206191RFKEA replace RMCS1206FT191R directly?

A: Yes. Both parts share identical electrical specifications (191 Ohms ±1%, 0.25W), composition (thick film), package (1206), and operating parameters. CRCW1206191RFKEA includes AEC-Q200 automotive qualification, which is an additional feature not present in the main part.

Q: What is the difference between RC1206FR-07191RL and RMCS1206FT191R?

A: Both parts are electrically and mechanically equivalent. RC1206FR-07191RL features moisture-resistant construction, while RMCS1206FT191R features anti-sulfur construction. Both are Active products suitable for new designs.

Q: Why is ERJ-8ENF1910V marked as Not For New Designs?

A: ERJ-8ENF1910V is classified as Not For New Designs by Panasonic. This part should be used only for replacement in existing systems. For new designs, select CRCW1206191RFKEA or RC1206FR-07191RL.

Q: Are all substitute parts 1206 package compatible?

A: Yes. All substitute parts use the 1206 (3216 Metric) package with identical footprint requirements. Dimensional variations (length, width, height) are within standard PCB assembly tolerances.

Q: Do all parts meet RoHS3 compliance?

A: Yes. RMCS1206FT191R, CRCW1206191RFKEA, ERJ-8ENF1910V, and RC1206FR-07191RL are all ROHS3 compliant with MSL rating 1 (Unlimited).
