Substitute Part Grouping Explanation

Substitute parts for PRNF14FTD75R0 are grouped based on the following allowed substitution parameters:

Primary Substitution Criteria:

• Resistance value: 75 Ohms (fixed)
• Tolerance: ±1% (fixed)
• Composition: Metal Film (fixed)
• Operating temperature range: -55°C to 155°C (fixed)
• Package type: Axial (fixed)
• Physical dimensions: 0.093" Dia x 0.250" L (fixed)
• Compliance: ROHS3 Compliant, REACH Unaffected (fixed)

Variable Parameters Allowing Substitution:

• Packaging format (Tape & Reel vs. Cut Tape)
• Power rating (0.25W or 0.5W)
• Temperature coefficient (±100ppm/°C or ±50ppm/°C)
• Series designation (RNF or RNMF)

The PRNF14FTD75R0 (Tape & Reel packaging) can be directly substituted with RNF14FTD75R0 (Cut Tape packaging) as both maintain identical electrical and mechanical specifications with only packaging format differentiation. RNF14FTC75R0 provides enhanced temperature stability at ±50ppm/°C while maintaining all other parameters. RNMF12FTD75R0 offers increased power dissipation at 0.5W for applications requiring higher thermal capacity.

Engineering Selection Recommendations

RNF14FTD75R0 (Cut Tape Packaging): Direct functional equivalent to PRNF14FTD75R0 with identical electrical specifications. Selection is appropriate when Cut Tape packaging format is preferred over Tape & Reel. Both parts maintain ROHS3 compliance and active production status.

RNF14FTC75R0 (Enhanced Temperature Stability): Suitable for applications requiring improved temperature coefficient performance at ±50ppm/°C compared to the standard ±100ppm/°C specification. Maintains all other electrical and mechanical parameters. ROHS3 compliant and active production status.

RNMF12FTD75R0 (Increased Power Dissipation): Appropriate for circuits requiring higher power handling capacity at 0.5W rating versus the standard 0.25W. Maintains 75 Ohm resistance, ±1% tolerance, and all compliance certifications. ROHS3 compliant and active production status.

All substitute parts are manufactured by Stackpole Electronics Inc and maintain compliance with ROHS3 and REACH requirements, ensuring regulatory compatibility with the original PRNF14FTD75R0 specification.

Frequently Asked Questions (FAQ)

Q: Can RNF14FTD75R0 (Cut Tape) be used as a direct replacement for PRNF14FTD75R0 (Tape & Reel)?

A: Yes. Both parts are electrically and mechanically identical with 75 Ohm resistance, ±1% tolerance, 0.25W power rating, and identical physical dimensions. The only difference is packaging format. Selection depends on assembly process requirements and inventory management preferences.

Q: What is the advantage of RNF14FTC75R0 over PRNF14FTD75R0?

A: RNF14FTC75R0 provides enhanced temperature stability with a temperature coefficient of ±50ppm/°C compared to ±100ppm/°C in PRNF14FTD75R0. This results in more stable resistance values across the operating temperature range of -55°C to 155°C. All other specifications remain identical.

Q: When should RNMF12FTD75R0 be selected instead of PRNF14FTD75R0?

A: RNMF12FTD75R0 should be selected when the circuit requires higher power dissipation capability. This part is rated at 0.5W (1/2W) compared to the 0.25W (1/4W) rating of PRNF14FTD75R0. Resistance value, tolerance, and all other electrical parameters remain identical.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. PRNF14FTD75R0, RNF14FTD75R0, RNF14FTC75R0, and RNMF12FTD75R0 are all ROHS3 compliant and REACH unaffected, ensuring regulatory compatibility across all substitute options.

Q: Do the substitute parts maintain the same physical dimensions?

A: Yes. All substitute parts maintain the same axial package dimensions of 0.093" Dia x 0.250" L (2.35mm x 6.35mm), ensuring mechanical compatibility with existing PCB layouts and assembly processes.

Q: What is the difference between RNF and RNMF series designations?

A: The RNMF series represents the Mini variant with higher power rating (0.5W) compared to the standard RNF series (0.25W). Both series maintain identical resistance values, tolerance, and physical dimensions for the specified parts.
