RUT3216JR750CS Equivalent & Substitute Parts

Part Overview

The RUT3216JR750CS is a 750 mOhms ±5% thick film chip resistor in 1206 (3216 Metric) package manufactured by Samsung Electro-Mechanics. This current sense resistor is designed for precision measurement applications requiring low resistance values with moisture resistance. The part is Active status and ROHS3 compliant. Substitute parts are identified when equivalent electrical and mechanical specifications can be maintained while offering improved tolerance, packaging format, or inventory availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RUT3216JR750CS is determined by strict equivalence in the following critical parameters:

Mandatory Equivalence Parameters:

• Resistance value: 750 mOhms
• Power rating: 0.333W (1/3W)
• Package type: 1206 (3216 Metric)
• Composition: Thick Film
• Features: Current Sense, Moisture Resistant
• Temperature coefficient: ±150ppm/°C
• Operating temperature range: -55°C ~ 155°C
• RoHS compliance: ROHS3 Compliant
• MSL rating: 1 (Unlimited)

Allowable Variation Parameters:

• Tolerance: May be tighter (lower value) than ±5%
• Packaging format: May differ (Tape & Reel vs. Cut Tape)
• Height seated maximum: Minor variations acceptable within mechanical constraints

The RUT3216FR750CS qualifies as a substitute because it maintains all mandatory equivalence parameters while offering improved tolerance specification (±1% versus ±5%) and alternative packaging format (Cut Tape versus Tape & Reel).

Parameter Comparison

Engineering Selection Recommendations

RUT3216JR750CS Selection Criteria:

• Applications requiring ±5% tolerance specification
• Tape & Reel packaging format for automated assembly processes
• Designs where tolerance specification is explicitly defined as ±5%

RUT3216FR750CS Selection Criteria:

• Applications benefiting from improved ±1% tolerance specification
• Cut Tape packaging format for manual or selective assembly processes
• Designs where tighter tolerance improves measurement accuracy in current sensing circuits
• Scenarios where higher inventory availability is advantageous

Both parts maintain identical electrical performance in core parameters (resistance, power rating, temperature coefficient, operating range) and equivalent mechanical fit (1206 package, identical dimensions). Both are Active status products from Samsung Electro-Mechanics with ROHS3 compliance and unlimited MSL rating. Selection between these parts is determined by tolerance requirement and packaging format preference.

Frequently Asked Questions (FAQ)

Q: Can RUT3216FR750CS replace RUT3216JR750CS in existing designs?

A: Yes. The RUT3216FR750CS maintains all critical electrical and mechanical parameters. The primary difference is tolerance specification (±1% versus ±5%). If the design circuit tolerates ±1% tolerance, direct substitution is valid. If the design specifically requires ±5% tolerance, substitution is not appropriate.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging supplies components on continuous tape wound on reels, suitable for high-volume automated assembly. Cut Tape (CT) packaging supplies components on tape segments, suitable for lower-volume or manual assembly processes. Both formats contain identical components; packaging format selection depends on assembly process requirements.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts are 1206 (3216 Metric) package with dimensions 0.126" L x 0.063" W (3.20mm x 1.60mm). Height seated maximum differs by 0.01mm (0.66mm versus 0.65mm), which is negligible for PCB assembly and does not affect substitutability.

Q: Do both parts meet the same compliance standards?

A: Yes. Both RUT3216JR750CS and RUT3216FR750CS are ROHS3 compliant, REACH unaffected, and carry MSL rating 1 (Unlimited). Both are classified under ECCN EAR99 and HTSUS 8533.21.0030.

Q: What determines whether a part qualifies as a substitute?

A: Substitution is valid when the alternative part maintains identical values for: resistance, power rating, package type, composition, features, temperature coefficient, operating temperature range, and compliance certifications. Tolerance may be tighter (lower value) than the original specification. Packaging format may differ without affecting substitutability.
