Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F1401CS is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Resistance value (1.4 kOhms), tolerance (±1%), and power rating (0.25W) must be identical. 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) are mandatory for PCB compatibility. Physical dimensions must accommodate standard 1206 footprints.

Environmental & Compliance: All substitute parts must maintain ROHS3 compliance, MSL 1 rating, and REACH unaffected status. Composition (thick film) ensures consistent electrical behavior.

The five identified substitute parts meet all these criteria and are therefore direct functional equivalents suitable for circuit replacement without design modification.

Frequently Asked Questions (FAQ)

Q: Can ERJ-8ENF1401V be used in new circuit designs? A: ERJ-8ENF1401V carries "Not For New Designs" status. This part is suitable for replacement and repair of existing assemblies but should not be selected for new product development. Use AC1206FR-071K4L, CR1206-FX-1401ELF, CRCW12061K40FKEA, or RC1206FR-071K4L for new designs.

Q: Are there dimensional differences between substitute parts? A: All parts use the 1206 (3216 Metric) package. Minor variations exist in maximum seated height (0.024" to 0.030"), which do not affect PCB footprint compatibility. Length and width dimensions range from 0.122" to 0.126" (3.10mm to 3.20mm), all within standard 1206 tolerance.

Q: What is the difference between automotive-qualified and standard versions? A: AC1206FR-071K4L, CRCW12061K40FKEA, and ERJ-8ENF1401V carry AEC-Q200 automotive qualification. CR1206-FX-1401ELF and RC1206FR-071K4L are standard industrial-grade parts. Both types meet identical electrical specifications and are mechanically interchangeable. Automotive versions are required only for applications subject to automotive reliability standards.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts and the main part RCS3216F1401CS are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: Which substitute has the highest inventory availability? A: RC1206FR-071K4L (YAGEO) has the highest stock level at 86,268 units, followed by CR1206-FX-1401ELF (Bourns Inc.) at 25,874 units.

Q: Can these parts be used interchangeably on the same PCB assembly? A: Yes. All substitute parts are direct functional equivalents with identical electrical parameters, package type, and environmental ratings. They can be used interchangeably without circuit modification or re-qualification.
