Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RMCS1206FT464R is determined by strict equivalence across the following parameters: resistance value (464 Ohms), tolerance (±1%), power rating (0.25W), package type (1206), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and compliance certifications (ROHS3, MSL 1). All identified substitute parts maintain these core electrical and mechanical specifications. Variations in physical dimensions (length, width, height) within standard manufacturing tolerances and differences in feature sets (automotive qualification, moisture resistance) do not affect functional substitutability in standard applications.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts maintain full electrical and mechanical compatibility with the RMCS1206FT464R. Selection among alternatives should be based on product lifecycle status and application requirements:

CRCW1206464RFKEA (Vishay Dale) and RC1206FR-07464RL (YAGEO) are both active production parts suitable for new designs. CRCW1206464RFKEA carries automotive AEC-Q200 qualification, making it appropriate for automotive applications. RC1206FR-07464RL features moisture-resistant construction and is suitable for general industrial applications.

ERJ-8ENF4640V (Panasonic) is marked as "Not For New Designs" and should be used only for legacy system maintenance or repair applications where original part continuity is required. This part carries automotive AEC-Q200 qualification but is being phased out.

Frequently Asked Questions (FAQ)

Q: Can CRCW1206464RFKEA replace RMCS1206FT464R in all applications? A: Yes. Both parts share identical electrical specifications (464 Ohms ±1%, 0.25W), temperature coefficient (±100ppm/°C), operating range (-55°C to 155°C), and package footprint (1206). CRCW1206464RFKEA includes automotive AEC-Q200 qualification, which provides additional qualification for automotive environments but does not restrict use in standard applications.

Q: What is the difference between anti-sulfur and moisture-resistant features? A: Anti-sulfur construction (RMCS1206FT464R) protects against sulfur-containing atmospheric corrosion. Moisture-resistant construction (RC1206FR-07464RL) provides protection against moisture ingress. Both are thick film resistors with identical electrical performance. Feature selection depends on environmental exposure conditions.

Q: Why is ERJ-8ENF4640V marked "Not For New Designs"? A: This designation indicates the manufacturer is discontinuing the part for new applications. Existing inventory remains available for legacy system support and repair. New designs should use CRCW1206464RFKEA or RC1206FR-07464RL.

Q: Are physical dimension variations between substitute parts significant? A: Physical dimensions vary slightly within standard manufacturing tolerances (length 0.122" to 0.126", height 0.024" to 0.028"). These variations are within PCB design tolerances for 1206 package footprints and do not affect functional compatibility or reflow soldering processes.

Q: Do all substitute parts meet the same compliance standards? A: Yes. All parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. All share identical ECCN (EAR99) and HTSUS (8533.21.0030) classifications.
