Key Parameters

Substitute Part Grouping Explanation

The RNF14FTE953R has one identified substitute: RNF14BTE953R. Substitution eligibility is determined by the following critical parameters:

• Resistance value: 953 Ohms (exact match required)
• Power rating: 0.25W (1/4W) (exact match required)
• Composition: Metal Film (exact match required)
• Package type: Axial (exact match required)
• Operating temperature range: -55°C to 155°C (exact match required)
• Temperature coefficient: ±25ppm/°C (exact match required)
• Physical dimensions: 0.093" Dia x 0.250" L (exact match required)

The substitute part RNF14BTE953R meets all these critical parameters. The primary difference is an improved tolerance specification (±0.1% versus ±1%) and a different packaging format (Cut Tape versus Tape & Reel).

Parameter Comparison

Engineering Selection Recommendations

Both RNF14FTE953R and RNF14BTE953R are active products manufactured by Stackpole Electronics Inc and maintain full ROHS3 compliance. Selection between these parts is determined by application requirements and packaging constraints:

RNF14FTE953R is appropriate for applications where standard ±1% tolerance meets circuit specifications and Tape & Reel packaging is preferred for automated assembly processes.

RNF14BTE953R is appropriate for applications requiring improved tolerance performance (±0.1%) or where Cut Tape packaging format is specified. The tighter tolerance reduces resistive value drift across the specified operating temperature range and manufacturing process variations.

Both parts share identical electrical characteristics regarding power rating, temperature coefficient, and operating temperature range, ensuring functional equivalence in circuits where tolerance requirements are not the limiting factor.

Frequently Asked Questions (FAQ)

Q: Can RNF14BTE953R directly replace RNF14FTE953R in existing designs?

A: Yes. Both parts maintain identical resistance value (953 Ohms), power rating (0.25W), composition (metal film), package type (axial), physical dimensions, and operating temperature range. The substitute part features improved tolerance (±0.1% versus ±1%), which provides enhanced precision without compromising compatibility.

Q: What is the significance of the tolerance difference between these parts?

A: Tolerance defines the acceptable deviation of the actual resistance value from the nominal 953 Ohm specification. RNF14FTE953R allows ±1% deviation (931.53 to 974.47 Ohms), while RNF14BTE953R allows ±0.1% deviation (952.047 to 953.953 Ohms). Applications requiring tighter resistive accuracy benefit from the RNF14BTE953R specification.

Q: How do packaging formats differ between these parts?

A: RNF14FTE953R is supplied in Tape & Reel (TR) format, optimized for high-volume automated assembly. RNF14BTE953R is supplied in Cut Tape (CT) format, suitable for lower-volume applications or manual assembly processes. Both formats contain identical components; packaging selection depends on assembly methodology and order quantity requirements.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both RNF14FTE953R and RNF14BTE953R are ROHS3 compliant and REACH unaffected, meeting current electronic component regulatory requirements for hazardous substance restrictions.

Q: Do these parts have identical thermal characteristics?

A: Yes. Both parts share identical temperature coefficient (±25ppm/°C) and operating temperature range (-55°C to 155°C), ensuring equivalent thermal performance across specified environmental conditions.
