Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RNF12FTD130R is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 130 Ohms
• Power rating: 0.5W (1/2W)
• Package type: Axial
• Physical dimensions: 0.108" Dia x 0.344" L (2.75mm x 8.75mm)
• Composition: Metal Film
• Operating temperature range: -55°C to 155°C
• Compliance: ROHS3 Compliant, REACH Unaffected

Allowable Variation Parameters:

• Tolerance: May be tighter (lower value) than ±1%
• Temperature coefficient: May be lower (better stability) than ±100ppm/°C
• Packaging format: Tape & Reel (TR) or Cut Tape (CT) are interchangeable for component-level selection

The RNF12DTC130R qualifies as a direct substitute because it maintains all mandatory parameters while offering improved tolerance (±0.5%) and superior temperature coefficient (±50ppm/°C), with the only difference being the packaging format change from Tape & Reel to Cut Tape.

Parameter Comparison

Engineering Selection Recommendations

The RNF12DTC130R is a qualified substitute for the RNF12FTD130R in all applications where the original part is specified. Both parts maintain identical electrical performance within the 130 Ohms resistance class and share equivalent mechanical compatibility for axial through-hole mounting.

The RNF12DTC130R offers performance advantages through tighter tolerance (±0.5% versus ±1%) and improved temperature stability (±50ppm/°C versus ±100ppm/°C), making it suitable for precision applications with stricter accuracy requirements. Both parts satisfy ROHS3 and REACH compliance requirements.

Selection between these parts should be based on packaging format requirements: Tape & Reel format for automated assembly processes, or Cut Tape format for manual assembly or lower-volume applications. Inventory availability (5428 units for RNF12DTC130R versus 816 units for RNF12FTD130R) may influence procurement decisions for high-volume production.

Frequently Asked Questions (FAQ)

Q: Can RNF12DTC130R replace RNF12FTD130R in existing designs? A: Yes. Both parts are electrically and mechanically identical in all critical parameters. The RNF12DTC130R offers superior tolerance and temperature coefficient performance, making it a direct upgrade substitute.

Q: What is the difference between Tape & Reel and Cut Tape packaging? A: Tape & Reel (TR) packaging is used for high-speed automated assembly equipment. Cut Tape (CT) packaging provides individual component strips suitable for manual assembly, lower-volume production, or component-level inventory management. The electrical and mechanical specifications remain unchanged.

Q: Are both parts RoHS compliant? A: Yes. Both RNF12FTD130R and RNF12DTC130R are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.

Q: What determines substitution eligibility for these resistors? A: Substitution is valid when resistance value, power rating, package type, physical dimensions, composition, operating temperature range, and compliance certifications remain identical. Tolerance and temperature coefficient may be equal or superior in the substitute part.

Q: Which part should be selected for precision applications? A: The RNF12DTC130R is recommended for applications requiring tighter tolerance control, as its ±0.5% tolerance and ±50ppm/°C temperature coefficient provide superior accuracy compared to the RNF12FTD130R specifications.
