Substitute Part Grouping Explanation

Substitution eligibility for the PRNF14FTD7K50 is determined by strict equivalence across the following critical parameters:

• Resistance value: 7.5 kOhms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Composition: Metal Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• Package configuration: Axial leads
• Physical dimensions: 0.093" Dia x 0.250" L (2.35mm x 6.35mm)
• Compliance certifications: RoHS3 Compliant, REACH Unaffected

The identified substitute part RNF14FAD7K50 maintains identical electrical and mechanical specifications. The primary distinction is packaging format: PRNF14FTD7K50 is supplied in Cut Tape (CT) configuration, while RNF14FAD7K50 is supplied in Tape & Box (TB) configuration. Both parts originate from Stackpole Electronics Inc RNF series and satisfy all substitution criteria.

Parameter Comparison

Engineering Selection Recommendations

All three parts—PRNF14FTD7K50, RNF14FAD7K50, and RNF14FTD7K50—maintain Active product status with full RoHS3 compliance and REACH unaffected certification. Selection between these parts should be based on packaging requirements and supply chain availability rather than electrical or mechanical performance differences.

PRNF14FTD7K50 and RNF14FTD7K50 are functionally equivalent alternatives supplied in Cut Tape (CT) format. RNF14FAD7K50 provides an equivalent substitute in Tape & Box (TB) packaging. All parts satisfy identical electrical specifications and environmental operating conditions.

Frequently Asked Questions (FAQ)

Q: Can RNF14FAD7K50 replace PRNF14FTD7K50 in production assembly?

A: Yes. Both parts are electrically and mechanically identical. The difference is packaging format: RNF14FAD7K50 uses Tape & Box (TB) while PRNF14FTD7K50 uses Cut Tape (CT). Compatibility depends on your assembly equipment's tape handling capability.

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

A: Cut Tape (CT) supplies components on continuous carrier tape without a box. Tape & Box (TB) includes the same carrier tape but packaged in a protective box. Both formats contain identical components with the same electrical and mechanical specifications.

Q: Are all three parts interchangeable?

A: Electrically and mechanically, yes. PRNF14FTD7K50, RNF14FAD7K50, and RNF14FTD7K50 share identical resistance, tolerance, power rating, temperature coefficient, operating range, and physical dimensions. Selection depends on packaging format availability and assembly process requirements.

Q: Do these parts meet compliance requirements for RoHS and REACH?

A: All three parts are RoHS3 Compliant and REACH Unaffected, meeting current regulatory standards for electronic component use in restricted substance directives.

Q: What determines substitution eligibility for this resistor?

A: Substitution is valid when resistance value, tolerance, power rating, composition, temperature coefficient, operating temperature range, package configuration, physical dimensions, and compliance certifications remain identical across parts.
