RNF14BAC250R Equivalent & Substitute Parts

Part Overview

The RNF14BAC250R is a 250 Ohm metal film through-hole resistor manufactured by Stackpole Electronics Inc. This component is rated for 0.25W (1/4W) power dissipation with ±0.1% tolerance and features flame retardant coating with safety certification. The part is currently in active production status with 770 units available in stock. Alternative models are necessary to accommodate different packaging requirements in manufacturing workflows, particularly when tape and reel packaging is preferred over tape and box configurations for automated assembly processes.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RNF14BAC250R is determined by the following critical parameters:

• Resistance value: 250 Ohms (exact match required)
• Tolerance: ±0.1% (exact match required)
• Power rating: 0.25W / 1/4W (exact match required)
• Composition: Metal Film (exact match required)
• Temperature coefficient: ±50ppm/°C (exact match required)
• Operating temperature range: -55°C to 155°C (exact match required)
• Package configuration: Axial through-hole (exact match required)
• Physical dimensions: 0.093" Dia × 0.250" L (exact match required)
• Compliance certifications: ROHS3 Compliant, REACH Unaffected (exact match required)

The RNF14BTC250R qualifies as a direct substitute because it maintains identical electrical specifications, physical dimensions, and compliance certifications. The only difference is the packaging format: tape and reel (TR) versus tape and box (TB).

Parameter Comparison

Engineering Selection Recommendations

Both the RNF14BAC250R and RNF14BTC250R are active production components from Stackpole Electronics Inc with full ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on packaging requirements:

• RNF14BAC250R (Tape & Box): Suitable for manual assembly, kit packaging, or applications where individual component handling is required.
• RNF14BTC250R (Tape & Reel): Suitable for automated pick-and-place assembly systems and high-volume manufacturing workflows.

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

Frequently Asked Questions (FAQ)

Q: Can RNF14BTC250R be used as a direct replacement for RNF14BAC250R?

A: Yes. The RNF14BTC250R is a direct electrical and mechanical equivalent. The only difference is packaging format (tape and reel versus tape and box). Both parts have identical resistance, tolerance, power rating, temperature characteristics, and physical dimensions.

Q: What is the difference between Tape & Box and Tape & Reel packaging?

A: Tape & Box (TB) packaging supplies components in a taped strip contained within a box, typically used for manual assembly or smaller quantity orders. Tape & Reel (TR) packaging supplies components on a continuous reel, optimized for automated assembly equipment and high-volume production.

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

A: No. Both parts are manufactured from the same metal film composition with identical resistance values, tolerance specifications, temperature coefficients, and operating temperature ranges. Electrical performance is equivalent.

Q: Do both parts meet the same compliance standards?

A: Yes. Both RNF14BAC250R and RNF14BTC250R are ROHS3 compliant and REACH unaffected. They meet identical regulatory requirements.

Q: Which part should I select for automated assembly?

A: The RNF14BTC250R (Tape & Reel) is the appropriate choice for automated pick-and-place assembly systems. The tape and reel format is designed for compatibility with standard component feeders used in manufacturing equipment.

Q: Can I mix these parts in the same assembly?

A: Yes. Since both parts are electrically and mechanically identical, they can be used interchangeably within the same circuit or assembly without any functional impact.
