Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F3093CS is determined by strict equivalence across the following critical parameters:

Electrical Specifications: Resistance value (309 kOhms), tolerance (±1%), and power rating (0.25W) must be identical. Temperature coefficient (±100ppm/°C) and operating temperature range (-55°C ~ 155°C) establish thermal performance boundaries.

Mechanical Compatibility: Package designation (1206 / 3216 Metric) and number of terminations (2) ensure physical and electrical interface compatibility with PCB layouts designed for the main part.

Environmental & Compliance Requirements: Moisture Sensitivity Level 1 (Unlimited), ROHS3 compliance, and REACH unaffected status establish baseline environmental and regulatory compatibility.

All identified substitute parts meet these criteria without exception. Variations in specific features (such as anti-sulfur coating or automotive AEC-Q200 qualification) represent functional enhancements rather than substitution barriers, as these features do not conflict with the main part's application requirements.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (Active Status, Standard Features):

CR1206-FX-3093ELF (Bourns Inc.) and RC1206FR-07309KL (YAGEO) are recommended as primary substitutes. Both parts maintain Active product status, ensuring long-term availability and manufacturing support. These options provide moisture-resistant thick film construction with full compliance to ROHS3 and REACH requirements. Inventory availability is substantial (25,996 and 133,118 pieces respectively), supporting production continuity.

Secondary Selection (Automotive-Qualified Applications):

CRCW1206309KFKEA (Vishay Dale) is suitable for applications requiring automotive-grade components. This part carries AEC-Q200 qualification, indicating suitability for automotive environments. Product status remains Active with 19,243 pieces in inventory. Selection of this part is appropriate when automotive reliability standards are specified in design requirements.

Legacy Applications Only:

ERJ-8ENF3093V (Panasonic Electronic Components) carries a "Not For New Designs" product status designation. This part is electrically and mechanically equivalent but should be used only in legacy system maintenance or repair scenarios where original part continuity is required. Despite high inventory (51,488 pieces), new design implementations should avoid this part number.

Frequently Asked Questions (FAQ)

Q: Can CR1206-FX-3093ELF directly replace RCS3216F3093CS in existing PCB layouts?

A: Yes. Both parts share identical 1206 (3216 Metric) package dimensions, two-terminal configuration, and electrical specifications (309 kOhms ±1%, 0.25W). Physical footprint compatibility is confirmed. No PCB redesign is required.

Q: What is the difference between the Samsung RCS3216F3093CS and YAGEO RC1206FR-07309KL?

A: Both parts are electrically and mechanically equivalent with matching resistance, tolerance, power rating, and operating temperature range. The primary difference is manufacturer identity and packaging format. Samsung specifies anti-sulfur coating as an additional feature; YAGEO specifies moisture resistance. Both meet MSL 1 and ROHS3 requirements. Selection between these parts is based on supply chain preference and inventory availability.

Q: Why is ERJ-8ENF3093V marked "Not For New Designs"?

A: The "Not For New Designs" status indicates that Panasonic has designated this part for legacy support only. While electrically and mechanically equivalent, new product designs should select from Active-status alternatives (CR1206-FX-3093ELF, CRCW1206309KFKEA, or RC1206FR-07309KL) to ensure long-term manufacturing support and design continuity.

Q: Is CRCW1206309KFKEA suitable for non-automotive applications?

A: Yes. AEC-Q200 automotive qualification is a superset of standard industrial requirements. This part meets all electrical, mechanical, and environmental specifications required for standard industrial applications. Automotive qualification does not restrict use in non-automotive designs; it confirms enhanced reliability testing and performance validation.

Q: What is the significance of MSL 1 (Unlimited) rating across all parts?

A: MSL 1 (Unlimited) indicates that these resistors have unlimited shelf life without moisture bake-out requirements. No special storage conditions or pre-reflow handling procedures are necessary. All substitute parts share this rating with the main part, confirming equivalent moisture sensitivity performance.

Q: Are there dimensional variations between substitute parts that affect PCB assembly?

A: All parts conform to 1206 (3216 Metric) package specification. Seated height variations (ranging from 0.024" to 0.030") fall within standard PCB assembly tolerances and do not affect pick-and-place equipment compatibility or solder reflow processes. These minor dimensional differences do not impact functional performance or assembly procedures.
