Key Parameters

Substitute Part Grouping Explanation

Substitution validity for the RMCS1206FT56K2 is determined by strict equivalence across the following parameters:

• Resistance value: 56.2 kOhms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Package: 1206 (3216 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Termination count: 2
• Moisture sensitivity level: 1 (Unlimited)

All identified substitute parts meet these core electrical and mechanical parameters. Variations in physical dimensions (length, width, height) within standard 1206 package tolerances, manufacturer-specific features (anti-sulfur, moisture resistant, automotive AEC-Q200), and compliance certifications do not affect functional substitutability but may influence selection based on application requirements.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain electrical and mechanical equivalence to the RMCS1206FT56K2. Selection among alternatives should be based on the following criteria:

For Active Production Designs: CR1206-FX-5622ELF (Bourns), CRCW120656K2FKEA (Vishay Dale), and RC1206FR-0756K2L (YAGEO) are recommended. All three maintain active product status and ROHS3 compliance.

For Automotive Applications: CRCW120656K2FKEA and CRCW120656K2FKTA (both Vishay Dale) include AEC-Q200 automotive qualification. CRCW120656K2FKEA is preferred due to ROHS3 compliance; CRCW120656K2FKTA is RoHS non-compliant and REACH affected.

For Legacy or Existing Designs: ERJ-8ENF5622V (Panasonic) is available with high inventory (25,022 pieces) but carries "Not For New Designs" status. This part remains suitable for sustaining production of existing designs.

For Moisture-Resistant Applications: CR1206-FX-5622ELF and RC1206FR-0756K2L both feature moisture-resistant thick film composition.

For Supply Continuity: RC1206FR-0756K2L (YAGEO) offers the highest inventory level (42,638 pieces), followed by CR1206-FX-5622ELF (30,015 pieces).

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts interchangeably with the RMCS1206FT56K2?

A: Yes, all listed substitute parts are electrically and mechanically equivalent. They share identical resistance (56.2 kOhms), tolerance (±1%), power rating (0.25W), package (1206), composition (thick film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). Physical dimension variations within standard 1206 package tolerances do not affect circuit performance.

Q: What is the difference between the Vishay Dale CRCW120656K2FKEA and CRCW120656K2FKTA?

A: Both parts are electrically identical with AEC-Q200 automotive qualification. The primary difference is compliance status: CRCW120656K2FKEA is ROHS3 compliant and REACH unaffected, while CRCW120656K2FKTA is RoHS non-compliant and REACH affected. For new designs, CRCW120656K2FKEA is the preferred choice.

Q: Why is ERJ-8ENF5622V marked "Not For New Designs"?

A: This designation indicates the part is in mature or declining production phase. While it remains functionally equivalent and suitable for sustaining existing designs, it should not be selected for new product development. Alternative active-status parts are recommended for new designs.

Q: Are there any dimensional differences between these parts?

A: Minor dimensional variations exist within standard 1206 package tolerances. Length ranges from 0.122" to 0.126" (3.10mm to 3.20mm), width from 0.061" to 0.063" (1.55mm to 1.60mm), and height from 0.024" to 0.030" (0.60mm to 0.75mm). These variations do not affect PCB layout or circuit functionality for standard 1206 footprints.

Q: Which substitute part has the best availability?

A: RC1206FR-0756K2L (YAGEO) has the highest inventory at 42,638 pieces, followed by ERJ-8ENF5622V (Panasonic) at 25,022 pieces and CR1206-FX-5622ELF (Bourns) at 30,015 pieces.

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

A: Yes, all parts including the primary RMCS1206FT56K2 are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Which substitute part should I choose for automotive applications?

A: CRCW120656K2FKEA (Vishay Dale) is the recommended choice for automotive applications. It carries AEC-Q200 qualification, maintains active product status, and is ROHS3 compliant. CRCW120656K2FKTA also has AEC-Q200 qualification but is not RoHS compliant.
