Key Parameters

Substitute Part Grouping Explanation

Substitution logic for RN55D34R0FBSL is strictly founded on matching electrical parameters: resistance value (34 Ohms), tolerance (±1%), power rating (0.125W, 1/8W), and composition (Metal Film). Mechanical dimensions, package/case (Axial), termination count, and compliance characteristics including RoHS, MSL, and REACH status are also matched. Only parts meeting all these specified parameters and attributes are included as valid substitutes.

Key substitution parameters:

• Resistance
• Tolerance
• Power (Watts)
• Composition
• Features
• Temperature Coefficient
• Operating Temperature
• Package / Case
• Supplier Device Package
• Size / Dimension
• Number of Terminations
• RoHS Status
• MSL
• REACH Status
• ECCN
• HTSUS

Parameter Comparison

Engineering Selection Recommendations

Select RN55D34R0FB14 as a substitute for RN55D34R0FBSL only when a precise match is required for all provided technical and compliance fields. Both parts are classified as RoHS non-compliant and REACH affected; ensure compatibility with regulatory requirements. Both are active status components with matched parameters for electrical, mechanical, and package characteristics.

Frequently Asked Questions (FAQ)

Q1: What key parameters must match for a substitution between RN55D34R0FBSL and RN55D34R0FB14?
A1: Resistance, tolerance, power rating, composition, temperature coefficient, operating temperature, package/case, supplier device package, size/dimension, number of terminations, RoHS status, MSL, REACH status, ECCN, and HTSUS must all align.

Q2: Are both RN55D34R0FBSL and RN55D34R0FB14 suitable for identical military and safety-critical applications?
A2: Both parts are rated for military, flame retardant coating, moisture resistance, and safety features as per the provided specifications.

Q3: Do package form factors and termination counts present any selection limitations?
A3: Both substitutes share the same axial package and have two terminations, ensuring compatibility with standard axial resistor footprints.

Q4: How should compliance statuses such as RoHS and REACH be considered in part selection?
A4: Both components are RoHS non-compliant and REACH affected; selection should be contingent upon compliance requirements for the end application.

Q5: Can substitute selection be made solely on inventory availability?
A5: Substitute selection must be based only on matching all key specified electrical, mechanical, and compliance parameters; inventory is not a sole criterion.
