RMCF1206FT324R Equivalent & Substitute Parts

Part Overview

The RMCF1206FT324R is a 324 Ohm ±1% 0.25W thick film chip resistor in 1206 (3216 Metric) package manufactured by Stackpole Electronics Inc. This component is rated for automotive applications under AEC-Q200 standard with an operating temperature range of -55°C to 155°C. The part is currently active in production with 1217 pieces in stock inventory.

Substitute parts are necessary when the primary manufacturer experiences supply constraints, when design requirements mandate alternative qualified suppliers, or when inventory availability necessitates cross-manufacturer compatibility within the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RMCF1206FT324R is determined by strict equivalence across the following parameters:

• Resistance value: 324 Ohms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Package: 1206 (3216 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1 (Unlimited)

All substitute parts listed meet these core electrical and mechanical requirements. Variations in physical dimensions (length, width, height) within standard tolerances and differences in product status do not affect functional interchangeability in circuit applications.

Engineering Selection Recommendations

For new design implementations, select from parts with Active product status: RMCF1206FT324R (Stackpole Electronics Inc), CRCW1206324RFKEA (Vishay Dale), AC1206FR-07324RL (YAGEO), or RC1206FR-07324RL (YAGEO). All four maintain full AEC-Q200 automotive qualification and ROHS3 compliance.

The ERJ-8ENF3240V (Panasonic) carries a "Not For New Designs" status and should be used only for legacy system maintenance or replacement applications where the original specification requires this specific part number.

CRCW1206324RFKEA offers the highest inventory availability at 25504 pieces, providing supply chain stability for high-volume production. AC1206FR-07324RL and RC1206FR-07324RL are manufacturer-recommended alternatives from YAGEO with active production status and adequate stock levels.

Frequently Asked Questions (FAQ)

Q: Can CRCW1206324RFKEA replace RMCF1206FT324R in automotive applications?

A: Yes. Both parts meet identical electrical specifications (324 Ohms ±1%, 0.25W), operate across the same temperature range (-55°C to 155°C), carry AEC-Q200 automotive qualification, and are packaged in 1206 (3216 Metric) format. Physical dimension variations (height: 0.028" vs 0.024") fall within standard PCB assembly tolerances and do not affect circuit performance.

Q: Why is ERJ-8ENF3240V marked "Not For New Designs"?

A: This designation indicates the manufacturer (Panasonic) has discontinued active development for this part number. While the part remains functionally equivalent and in stock, it should not be specified for new product designs. Use active alternatives such as CRCW1206324RFKEA, AC1206FR-07324RL, or RC1206FR-07324RL instead.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 Compliant status and maintain MSL 1 (Unlimited) moisture sensitivity rating, meeting current environmental and regulatory requirements.

Q: What is the difference between AC1206FR-07324RL and RC1206FR-07324RL?

A: Both are YAGEO products with identical electrical specifications. AC1206FR-07324RL includes explicit AEC-Q200 automotive rating and moisture-resistant features. RC1206FR-07324RL specifies moisture-resistant composition without explicit automotive rating notation. Both operate across -55°C to 155°C and are suitable for automotive applications.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes. All substitute parts conform to 1206 (3216 Metric) package dimensions and land pattern requirements. Footprint compatibility is maintained across all listed alternatives.
