Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PRNF14FTD100R are categorized based on the following allowed parameters:

Direct Equivalents (Same Electrical and Mechanical Specifications):

• Resistance: 100 Ohms
• Tolerance: ±1%
• Power Rating: 0.25W (1/4W)
• Composition: Metal Film
• Package: Axial
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature: -55°C to 155°C

Substitution is permitted when packaging format (Tape & Reel, Cut Tape, Tape & Box) differs while maintaining identical electrical performance and mechanical dimensions.

Upgrade Substitutes (Enhanced Specifications):

• Increased power rating (0.5W or 1W) while maintaining 100 Ohm resistance and ±1% tolerance
• Improved tolerance (±0.1%) with higher power rating
• Extended operating temperature range
• Enhanced temperature coefficient performance
• Upgraded flame protection or moisture resistance features

All substitute parts maintain axial through-hole configuration and are ROHS3 compliant with REACH Unaffected status.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Identical Electrical Performance): RNF14FTD100R in Cut Tape format offers the highest inventory availability (140,969 pieces) while maintaining all electrical and mechanical specifications of the primary part. RNF14FAD100R provides equivalent performance in Tape & Box packaging for applications requiring alternative handling formats.

For Power Margin Applications: RNMF12FTD100R (Stackpole, 0.5W) and CMF55100R00FHEB (Vishay Dale, 0.5W) both provide doubled power rating while maintaining ±1% tolerance and 100 Ohm resistance. Both are ROHS3 compliant and suitable for circuits requiring thermal headroom.

For Precision and Extended Temperature Range: CMF55100R00BEEB offers ±0.1% tolerance with improved temperature coefficient (±25ppm/°C) and extended operating range to 175°C. This upgrade is appropriate for precision measurement circuits or applications in elevated temperature environments.

For Maximum Temperature and Power Capability: CPF1100R00FKEE6 (Vishay Dale, 1W) provides the highest power rating (1W) with extended operating temperature range (-65°C to 230°C). This part is suitable for high-dissipation or extreme temperature applications while maintaining ±1% tolerance.

All recommended substitutes maintain ROHS3 compliance and REACH Unaffected status, ensuring regulatory consistency with the primary part.

Frequently Asked Questions (FAQ)

Q: Can RNF14FAD100R replace PRNF14FTD100R directly? A: Yes. Both parts are 100 Ohm ±1% metal film resistors rated at 0.25W with identical electrical specifications and axial package dimensions. The difference is packaging format: RNF14FAD100R uses Tape & Box while PRNF14FTD100R uses Tape & Reel. Mechanical fit and electrical performance are equivalent.

Q: What is the difference between PRNF14FTD100R and RNF14FTD100R? A: Both are Stackpole RNF series 100 Ohm ±1% 0.25W axial resistors with identical electrical specifications. The primary difference is packaging: PRNF14FTD100R is supplied in Tape & Reel format, while RNF14FTD100R is supplied in Cut Tape format. RNF14FTD100R has significantly higher inventory availability.

Q: Can I use RNMF12FTD100R as a substitute for PRNF14FTD100R? A: Yes, with consideration for power rating. RNMF12FTD100R is rated at 0.5W (double the 0.25W rating of PRNF14FTD100R) and maintains ±1% tolerance and 100 Ohm resistance. It is suitable for direct replacement in applications where the higher power rating does not create thermal or space constraints. Both parts operate across -55°C to 155°C.

Q: What are the advantages of CMF55100R00BEEB over PRNF14FTD100R? A: CMF55100R00BEEB offers three upgrades: (1) doubled power rating (0.5W vs 0.25W), (2) improved tolerance (±0.1% vs ±1%), and (3) superior temperature coefficient (±25ppm/°C vs ±100ppm/°C). Operating temperature extends to 175°C. These enhancements are beneficial for precision circuits and elevated temperature environments.

Q: Is CPF1100R00FKEE6 compatible with PRNF14FTD100R applications? A: CPF1100R00FKEE6 is mechanically and electrically compatible as a substitute. It maintains 100 Ohm resistance and ±1% tolerance but offers quadrupled power rating (1W vs 0.25W) and extended operating temperature range (-65°C to 230°C). Use this part when applications require higher power dissipation or operation in extreme temperature conditions.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts are ROHS3 compliant and REACH Unaffected, maintaining regulatory consistency with PRNF14FTD100R.

Q: Which substitute offers the best inventory availability? A: RNF14FTD100R in Cut Tape format has the highest inventory at 140,969 pieces, followed by CMF55100R00FHEB at 6,805 pieces and RNMF12FTD100R at 5,870 pieces.
