Packaging Difference: The primary distinction between these parts is the supply format: RNF14FAD6M49 is supplied in Tape & Box (TB) packaging, while RNF14FTD6M49 is supplied in Cut Tape (CT) packaging. Both formats contain identical components suitable for automated assembly processes.

Parameter Comparison

Engineering Selection Recommendations

Both RNF14FAD6M49 and RNF14FTD6M49 are Active products from Stackpole Electronics Inc with full ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on assembly process requirements and packaging logistics:

• RNF14FAD6M49 (Tape & Box): Suitable for mixed manual and automated assembly operations where bulk packaging with protective boxing is preferred.
• RNF14FTD6M49 (Cut Tape): Optimized for high-volume automated pick-and-place assembly where cut tape feeding systems are standard.

Both parts deliver identical electrical performance and mechanical fit within the specified operating temperature range of -55°C to 155°C. Component selection does not impact circuit functionality or reliability characteristics.

Frequently Asked Questions (FAQ)

Q: Can RNF14FTD6M49 be used as a direct replacement for RNF14FAD6M49?

A: Yes. Both parts are electrically and mechanically identical with 6.49 MOhms resistance, ±1% tolerance, and 0.25W power rating. The only difference is packaging format (Cut Tape vs. Tape & Box). Direct substitution is valid for any application using the RNF14FAD6M49.

Q: What is the difference between Tape & Box (TB) and Cut Tape (CT) packaging?

A: Tape & Box packaging supplies components on continuous tape with protective boxing for storage and handling. Cut Tape packaging supplies components on tape segments pre-cut to specific lengths. Both formats contain identical components; packaging choice depends on assembly equipment compatibility and inventory management preferences.

Q: Are both parts RoHS compliant?

A: Yes. Both RNF14FAD6M49 and RNF14FTD6M49 are ROHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements for industrial and consumer applications.

Q: What is the operating temperature range for these resistors?

A: Both parts operate reliably from -55°C to 155°C with a temperature coefficient of ±100ppm/°C, ensuring stable resistance values across this temperature span.

Q: Can these axial resistors be used in both through-hole and surface-mount applications?

A: These components are designed for through-hole assembly only. The axial package with 2 terminations is configured for insertion into PCB holes. Surface-mount applications require different package types.
