Key Parameters

Substitute Part Grouping Explanation

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

Electrical Parameters: Resistance value (402 kOhms), tolerance (±1%), and power rating (0.25W) must match exactly. Temperature coefficient (±100ppm/°C) and operating temperature range (-55°C to 155°C) establish thermal performance boundaries.

Mechanical Parameters: Package type (1206 / 3216 Metric) and number of terminations (2) ensure physical and electrical compatibility with PCB layouts designed for the RC3216F4023CS.

Environmental & Compliance Parameters: RoHS3 compliance, MSL 1 rating, and REACH unaffected status are maintained across all substitutes to preserve regulatory and environmental performance.

Composition: All substitutes use thick film construction, maintaining consistent electrical behavior and reliability characteristics.

Substitute parts are classified into two categories:

Direct Substitutes: Parts meeting all electrical, mechanical, and environmental specifications with identical or equivalent performance characteristics. These include ERJ-8ENF4023V (Panasonic), RC1206FR-07402KL (YAGEO), and RMCF1206FT402K (Stackpole Electronics Inc).

Similar Substitutes: Parts meeting all core specifications with additional features or certifications (such as Automotive AEC-Q200 rating or High Voltage capability) that provide enhanced performance for specific application requirements. These include CRCW1206402KFKEA (Vishay Dale), KTR18EZPF4023 (Rohm Semiconductor), and MCR18ERTF4023 (Rohm Semiconductor).

Parameter Comparison

Engineering Selection Recommendations

For Active Product Designs: RC1206FR-07402KL (YAGEO), RMCF1206FT402K (Stackpole Electronics Inc), CRCW1206402KFKEA (Vishay Dale), and KTR18EZPF4023 (Rohm Semiconductor) are all classified as Active product status, ensuring continued availability and manufacturer support for new designs.

For Automotive Applications: RMCF1206FT402K, CRCW1206402KFKEA, KTR18EZPF4023, and ERJ-8ENF4023V carry Automotive AEC-Q200 certification, meeting automotive industry reliability and qualification standards. KTR18EZPF4023 additionally provides High Voltage capability for enhanced performance in demanding automotive environments.

For General Industrial Applications: RC1206FR-07402KL and the original RC3216F4023CS both feature moisture-resistant construction suitable for standard industrial operating conditions without automotive-specific requirements.

Inventory Considerations: CRCW1206402KFKEA offers the highest inventory availability (26,215 units), followed by RC1206FR-07402KL (9,418 units) and RMCF1206FT402K (5,214 units), providing supply chain flexibility for volume production requirements.

Discontinued Parts: MCR18ERTF4023 is discontinued at DiGi Electronics and should not be selected for new designs despite current inventory availability (1,903 units).

Frequently Asked Questions (FAQ)

Q: Can ERJ-8ENF4023V be used as a direct replacement for RC3216F4023CS?

A: ERJ-8ENF4023V meets all electrical and mechanical specifications (402 kOhm, ±1%, 0.25W, 1206 package, ±100ppm/°C, -55°C to 155°C). However, ERJ-8ENF4023V is classified as "Not For New Designs," indicating Panasonic has discontinued this product line. For new designs, select an Active-status substitute such as RC1206FR-07402KL or RMCF1206FT402K.

Q: What is the difference between moisture-resistant and automotive AEC-Q200 variants?

A: Moisture-resistant variants (RC3216F4023CS, RC1206FR-07402KL) are optimized for general industrial environments with protection against moisture ingress. Automotive AEC-Q200 variants (RMCF1206FT402K, CRCW1206402KFKEA, KTR18EZPF4023, ERJ-8ENF4023V) meet automotive industry qualification standards including thermal cycling, vibration, and reliability testing. Selection depends on application requirements: use moisture-resistant for standard industrial applications; use AEC-Q200 for automotive or mission-critical applications.

Q: Are all substitutes physically compatible with PCB layouts designed for RC3216F4023CS?

A: All listed substitutes use the 1206 (3216 Metric) package with 2 terminations, ensuring mechanical compatibility with existing PCB footprints. Physical dimensions vary slightly (length 3.05mm to 3.20mm, height 0.60mm to 0.70mm), but these variations remain within standard 1206 package tolerances and do not affect PCB assembly or electrical performance.

Q: Can KTR18EZPF4023 be used in applications where high voltage performance is not required?

A: Yes. KTR18EZPF4023 meets all core specifications for 402 kOhm, ±1%, 0.25W, 1206 package operation. The High Voltage feature is an additional capability that does not degrade performance in standard voltage applications. Selection of KTR18EZPF4023 is appropriate when high voltage capability provides design margin or future application flexibility.

Q: Why is MCR18ERTF4023 listed if it is discontinued?

A: MCR18ERTF4023 is included in the equivalents list for reference purposes and for applications where existing inventory must be managed or legacy designs require documentation. For new designs or production planning, select from Active-status alternatives: RC1206FR-07402KL, RMCF1206FT402K, CRCW1206402KFKEA, or KTR18EZPF4023.
