Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PRNF14FTD2M21 is determined by the following critical parameters:

• Resistance value: 2.21 MOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.25W / 1/4W (exact match required)
• Composition: Metal Film (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C to 155°C (exact match required)
• Package configuration: Axial leads (exact match required)
• Physical dimensions: 0.093" Dia × 0.250" L (exact match required)
• Compliance certifications: RoHS3, REACH unaffected (exact match required)

The primary variable distinguishing substitute parts is the supply packaging format (Tape & Reel versus Cut Tape), which does not affect component functionality or electrical performance.

Parameter Comparison

Engineering Selection Recommendations

Both the PRNF14FTD2M21 (Tape & Reel) and RNF14FTD2M21 (Cut Tape) are Active products from Stackpole Electronics Inc with identical electrical and mechanical specifications. Selection between these parts depends solely on procurement and assembly requirements:

• Tape & Reel packaging is suitable for high-volume automated assembly operations
• Cut Tape packaging is suitable for lower-volume applications, manual assembly, or mixed-component orders

Both variants maintain full RoHS3 compliance and REACH unaffected status, ensuring regulatory compatibility across all applications. No functional or performance differences exist between packaging formats.

Frequently Asked Questions (FAQ)

Q: Can RNF14FTD2M21 (Cut Tape) be used as a direct replacement for PRNF14FTD2M21 (Tape & Reel)?

A: Yes. Both parts are electrically and mechanically identical. The only difference is the supply packaging format. Substitution is valid for any application where the component specifications match the design requirements.

Q: What determines whether a part can substitute for the PRNF14FTD2M21?

A: Substitution requires exact matching of resistance value (2.21 MOhms), tolerance (±1%), power rating (0.25W), composition (Metal Film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), package type (Axial), physical dimensions (0.093" Dia × 0.250" L), and compliance certifications (RoHS3, REACH unaffected).

Q: Does packaging format affect component performance?

A: No. Tape & Reel and Cut Tape formats contain identical components. Packaging format only affects handling, storage, and assembly process compatibility.

Q: Are both parts currently available?

A: Yes. Both PRNF14FTD2M21 (Tape & Reel) and RNF14FTD2M21 (Cut Tape) maintain Active product status with current inventory availability.

Q: What compliance certifications apply to these parts?

A: Both parts are RoHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component use.
