Key Parameters

Substitute Part Grouping Explanation

The RNF14BTE953R qualifies as a direct substitute based on the following critical parameters:

• Identical resistance value: 953 Ohms
• Identical tolerance: ±0.1%
• Identical power rating: 0.25W (1/4W)
• Identical composition: Metal Film
• Identical package type: Axial Through Hole
• Identical physical dimensions: 0.093" Dia × 0.250" L
• Identical operating temperature range: -55°C to 155°C
• Identical RoHS3 compliance status
• Same manufacturer: Stackpole Electronics Inc
• Same series: RNF

The primary difference between these parts is the packaging format: the main part (RNF14BAC953R) is supplied in Tape & Box (TB) configuration, while the substitute (RNF14BTE953R) is supplied in Cut Tape (CT) configuration. Both packaging formats are standard industry options for the same component and do not affect electrical or mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

Both RNF14BAC953R and RNF14BTE953R are active production components from Stackpole Electronics Inc with full ROHS3 compliance and REACH unaffected status. The RNF14BTE953R offers improved temperature coefficient performance (±25ppm/°C versus ±50ppm/°C), which provides superior stability across the operating temperature range of -55°C to 155°C. The substitute part also maintains higher inventory availability at 2564 units compared to 1130 units for the main part.

Selection between these parts should be based on procurement requirements: Tape & Box packaging for bulk storage and manual assembly, or Cut Tape packaging for automated pick-and-place assembly systems. Both configurations deliver identical electrical performance and mechanical fit within the specified axial through-hole footprint.

Frequently Asked Questions (FAQ)

Q: Can RNF14BTE953R be used as a direct replacement for RNF14BAC953R in existing designs?

A: Yes. Both parts share identical electrical specifications (953 Ohms, ±0.1% tolerance, 0.25W power rating), composition (metal film), and physical dimensions (0.093" Dia × 0.250" L). The only difference is packaging format, which does not affect circuit performance or board-level compatibility.

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

A: Tape & Box packaging supplies components on continuous tape wound in a box, suitable for manual assembly and storage. Cut Tape packaging supplies components on tape cut into specific lengths, optimized for automated pick-and-place assembly equipment. Both formats contain the same component with identical specifications.

Q: Does the temperature coefficient difference affect substitution compatibility?

A: The RNF14BTE953R features a lower temperature coefficient (±25ppm/°C) compared to the RNF14BAC953R (±50ppm/°C). This represents an improvement in thermal stability and does not create any compatibility issues. The substitute part will perform within or better than the original specification across the full operating temperature range.

Q: Are both parts RoHS3 compliant?

A: Yes. Both RNF14BAC953R and RNF14BTE953R are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and use.

Q: Which part should be selected for new designs?

A: For new designs, either part is acceptable based on assembly process requirements. If automated assembly is used, select RNF14BTE953R (Cut Tape). If manual assembly or bulk storage is required, select RNF14BAC953R (Tape & Box). The RNF14BTE953R also offers superior temperature coefficient performance as an additional benefit.
