Substitute Part Grouping Explanation

The RNF18FAD4K75 has one direct equivalent substitute: RNF18FTD4K75. Both parts are manufactured by Stackpole Electronics Inc within the RNF series and share identical electrical and mechanical specifications. The substitution is valid based on the following matching parameters:

• Resistance value: 4.75 kOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Composition: Metal Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• Physical dimensions: 0.071" Dia × 0.130" L (1.80mm × 3.30mm)
• Axial package configuration
• RoHS3 compliance

The only difference between these parts is the packaging format: RNF18FAD4K75 is supplied in Tape & Box (TB) format, while RNF18FTD4K75 is supplied in Cut Tape (CT) format. Both formats contain identical components with no functional or performance variation.

Parameter Comparison

Engineering Selection Recommendations

Both RNF18FAD4K75 and RNF18FTD4K75 are active production components from Stackpole Electronics Inc with full ROHS3 compliance. Selection between these parts should be based on packaging requirements and supply availability:

• RNF18FAD4K75 (Tape & Box format) is suitable for applications requiring bulk packaging with protective boxing for storage and handling.
• RNF18FTD4K75 (Cut Tape format) is suitable for automated assembly processes and applications where cut tape packaging is preferred.

Both parts maintain identical electrical performance, mechanical compatibility, and regulatory compliance. The choice between them does not affect circuit functionality or reliability.

Frequently Asked Questions (FAQ)

Q: Can RNF18FTD4K75 be used as a direct replacement for RNF18FAD4K75?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (Tape & Box versus Cut Tape). The resistor components themselves are identical in all specifications.

Q: Are there any performance differences between these substitute parts?

A: No. Both parts have identical resistance values (4.75 kOhms), tolerance (±1%), power rating (0.125W), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C).

Q: What is the significance of the packaging format difference?

A: Packaging format affects handling, storage, and assembly processes. Tape & Box (TB) format provides protective boxing suitable for manual handling and storage. Cut Tape (CT) format is optimized for automated pick-and-place assembly equipment.

Q: Are both parts RoHS compliant?

A: Yes. Both RNF18FAD4K75 and RNF18FTD4K75 are ROHS3 compliant and meet REACH requirements.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes, provided the assembly process can accommodate the packaging format. The physical dimensions and electrical characteristics are identical, ensuring functional interchangeability in circuit applications.
