Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RMCS1206FT562K are qualified based on the following criteria:

Electrical Parameters: Resistance value (562 kOhms), tolerance (±1%), power rating (0.25W), and temperature coefficient (±100ppm/°C) must match exactly.

Package Compatibility: All substitutes use the 1206 (3216 Metric) surface mount package with 2 terminations. Physical dimensions must be compatible with standard 1206 footprints.

Environmental Ratings: Operating temperature range (-55°C ~ 155°C), RoHS3 compliance, and MSL 1 rating are maintained across all qualified substitutes.

Composition: All parts use thick film construction, ensuring consistent performance characteristics and thermal behavior.

The four qualified substitute parts meet these criteria while offering variations in features (anti-sulfur, moisture resistant, or automotive AEC-Q200 qualification) and availability levels.

Parameter Comparison

Engineering Selection Recommendations

For Active Production Designs: CR1206-FX-5623ELF (Bourns), CRCW1206562KFKEA (Vishay Dale), and RC1206FR-07562KL (YAGEO) are all active products suitable for new designs. These parts maintain full compliance with RoHS3 and MSL 1 requirements.

For Automotive Applications: CRCW1206562KFKEA carries AEC-Q200 automotive qualification, making it the appropriate choice for automotive circuit applications requiring this certification.

For Moisture-Critical Environments: CR1206-FX-5623ELF and RC1206FR-07562KL both feature moisture-resistant construction, providing enhanced protection in high-humidity or corrosive environments.

For Anti-Sulfur Requirements: RMCS1206FT562K (original part) provides anti-sulfur construction. If this specific feature is required, verify that substitute parts meet equivalent environmental protection standards for your application.

Avoid for New Designs: ERJ-8ENF5623V is marked "Not For New Designs" and should only be used for legacy system maintenance or replacement applications.

Frequently Asked Questions (FAQ)

Q: Can I substitute any of these parts directly into a circuit designed for RMCS1206FT562K?

A: Yes, all listed substitute parts share identical electrical specifications (562 kOhms ±1%, 0.25W, ±100ppm/°C) and operate across the same temperature range (-55°C ~ 155°C). All use the 1206 package with compatible footprints. Physical dimension variations are within standard 1206 tolerances and do not affect PCB layout compatibility.

Q: What is the difference between anti-sulfur and moisture-resistant features?

A: Anti-sulfur construction (RMCS1206FT562K) protects against sulfur-containing atmospheric contaminants. Moisture-resistant construction (CR1206-FX-5623ELF, RC1206FR-07562KL) provides protection against humidity and moisture ingress. Select based on your specific environmental exposure conditions.

Q: Are all these parts RoHS3 compliant?

A: Yes, all five parts listed are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, meeting standard industrial and commercial environmental requirements.

Q: Why is ERJ-8ENF5623V marked "Not For New Designs"?

A: This designation indicates the part is in mature or declining production status. While functionally equivalent and suitable for replacement or legacy applications, new circuit designs should specify one of the active production alternatives.

Q: Do these parts have different physical dimensions?

A: Minor dimensional variations exist within the 1206 package specification. RMCS1206FT562K and RC1206FR-07562KL measure 0.122" L × 0.061" W, while CR1206-FX-5623ELF, CRCW1206562KFKEA, and ERJ-8ENF5623V measure 0.126" L × 0.063" W. Height variations range from 0.024" to 0.030" maximum. These differences are within standard 1206 footprint tolerances and do not require PCB redesign.

Q: Which substitute offers the best availability?

A: CR1206-FX-5623ELF (Bourns) has the highest inventory at 25,690 units, followed by ERJ-8ENF5623V (Panasonic) at 20,175 units and RC1206FR-07562KL (YAGEO) at 16,454 units.
