RC3216F1243CS Equivalent & Substitute Parts

Part Overview

The RC3216F1243CS is a 124 kOhms ±1% 0.25W chip resistor manufactured by Samsung Electro-Mechanics in the 1206 (3216 Metric) package. This thick film, moisture-resistant component operates across -55°C to 155°C and is ROHS3 compliant with MSL 1 rating. The part is currently in active production status. Substitute parts are identified when equivalent electrical specifications, mechanical dimensions, and environmental ratings are required for design flexibility, inventory management, or supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RC3216F1243CS is determined by strict equivalence across the following parameters:

Electrical Specifications: Resistance value (124 kOhms), tolerance (±1%), power rating (0.25W), and temperature coefficient (±100ppm/°C) must be identical.

Mechanical Compatibility: Package designation (1206 / 3216 Metric), physical dimensions (0.126" L x 0.063" W / 3.20mm x 1.60mm), and termination count (2) must match or be compatible with PCB footprints designed for the original part.

Environmental & Compliance Requirements: Operating temperature range (-55°C ~ 155°C), moisture sensitivity level (MSL 1), RoHS3 compliance, and REACH unaffected status must be maintained.

Composition & Features: Thick film construction and moisture resistance are required characteristics.

All identified substitute parts meet these criteria. Variations in seated height and specific feature sets (such as automotive AEC-Q200 qualification) are noted but do not preclude substitution when electrical and mechanical parameters align.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: RC1206FR-07124KL (YAGEO) and CR1206-FX-1243ELF (Bourns) are direct equivalents with active product status and identical electrical specifications. Both are suitable for general applications requiring 124 kOhms ±1% 0.25W 1206 chip resistors.

Automotive Applications: CRCW1206124KFKEA (Vishay Dale) is the preferred substitute for designs requiring AEC-Q200 automotive qualification. This part maintains all electrical and mechanical equivalence while providing automotive-grade reliability certification.

Legacy Designs: ERJ-8ENF1243V (Panasonic) meets all electrical and mechanical parameters but carries a "Not For New Designs" status. This part is suitable only for sustaining production or replacement in existing designs where supply continuity is required.

Compliance Verification: All substitute parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment with the original RC3216F1243CS.

Frequently Asked Questions (FAQ)

Q: Can CR1206-FX-1243ELF replace RC3216F1243CS directly on the PCB?

A: Yes. Both parts share identical electrical specifications (124 kOhms ±1%), power rating (0.25W), package designation (1206), and operating temperature range (-55°C ~ 155°C). Seated height variation (0.030" vs 0.026") is within typical PCB assembly tolerances for 1206 components.

Q: What is the difference between the Bourns and YAGEO substitutes?

A: CR1206-FX-1243ELF (Bourns) and RC1206FR-07124KL (YAGEO) are electrically and mechanically equivalent. Primary differences are manufacturer, series designation, and minor seated height variation (0.030" vs 0.026"). Both are active products suitable for new designs.

Q: When should CRCW1206124KFKEA be selected over other substitutes?

A: CRCW1206124KFKEA is selected when automotive AEC-Q200 qualification is required by design specifications or end-use application. This part provides automotive-grade reliability certification while maintaining electrical equivalence.

Q: Is ERJ-8ENF1243V suitable for new product designs?

A: No. ERJ-8ENF1243V carries a "Not For New Designs" status. This part is restricted to sustaining production of existing designs or replacement applications where supply continuity is the primary concern.

Q: Do all substitute parts have the same moisture sensitivity level?

A: Yes. All substitute parts, including the original RC3216F1243CS, have MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage or handling.

Q: Are there dimensional constraints when substituting these parts?

A: Seated height varies across substitutes (0.024" to 0.030"). For standard PCB designs with 1206 footprints, these variations are accommodated by typical assembly processes. Applications with strict height constraints should reference specific seated height specifications.

Q: Do all substitutes maintain the same temperature coefficient?

A: Yes. All parts, including substitutes, have a temperature coefficient of ±100ppm/°C and operate across the identical temperature range of -55°C to 155°C.
