Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by matching the following core parameters: resistance value (75 Ohms), tolerance (±1%), composition (metal film), package type (axial), operating temperature range (-55°C to 155°C), and compliance certifications (ROHS3, REACH Unaffected). Substitutes are grouped by packaging format (Tape & Box, Cut Tape, Tape & Reel) and performance grade variations (temperature coefficient and power rating).

Direct Substitutes (Identical Electrical Performance):

• RNF14FTD75R0: Cut Tape packaging, identical specifications
• RNF14FTC75R0: Tape & Reel packaging, improved temperature coefficient (±50ppm/°C)

Upgrade Substitute (Higher Power Rating):

• RNMF12FTD75R0: 0.5W (1/2W) power rating, Tape & Reel packaging, same resistance and tolerance

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain Active product status and full compliance with ROHS3 and REACH requirements, ensuring regulatory continuity in design implementations.

RNF14FTD75R0 provides direct electrical and mechanical equivalence with identical specifications, differing only in packaging format (Cut Tape versus Tape & Box). This substitute is suitable for applications requiring standard tape packaging.

RNF14FTC75R0 offers improved temperature coefficient performance (±50ppm/°C versus ±100ppm/°C), maintaining identical power rating and resistance specifications. This upgrade is applicable to designs requiring enhanced temperature stability while preserving all other electrical characteristics.

RNMF12FTD75R0 provides increased power dissipation capability (0.5W versus 0.25W) with identical resistance, tolerance, and temperature range. This upgrade is applicable to circuits requiring higher power handling at the same resistance value. Physical dimensions remain unchanged, ensuring mechanical compatibility in existing board layouts.

Frequently Asked Questions (FAQ)

Q: Can RNF14FTD75R0 be used as a direct replacement for RNF14FAD75R0?

A: Yes. Both parts share identical electrical specifications (75 Ohms ±1%, 0.25W, ±100ppm/°C) and mechanical dimensions. The difference is packaging format: RNF14FAD75R0 is supplied in Tape & Box format, while RNF14FTD75R0 is supplied in Cut Tape format. Both are suitable for identical circuit applications.

Q: What is the advantage of RNF14FTC75R0 over the main part?

A: RNF14FTC75R0 features an improved temperature coefficient of ±50ppm/°C compared to ±100ppm/°C in RNF14FAD75R0. This provides superior temperature stability across the -55°C to 155°C operating range. All other specifications remain identical. Packaging format is Tape & Reel.

Q: When should RNMF12FTD75R0 be selected instead of RNF14FAD75R0?

A: RNMF12FTD75R0 should be selected when circuit design requires higher power dissipation. This part is rated at 0.5W (1/2W) versus 0.25W (1/4W) for RNF14FAD75R0. Resistance value, tolerance, and temperature range remain identical. Physical dimensions are unchanged, maintaining board layout compatibility.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. RNF14FTD75R0, RNF14FTC75R0, and RNMF12FTD75R0 are all ROHS3 compliant and REACH Unaffected, matching the compliance status of RNF14FAD75R0.

Q: Do packaging format differences affect circuit performance?

A: No. Tape & Box (TB), Cut Tape (CT), and Tape & Reel (TR) are supply format variations only. They do not affect electrical performance or mechanical fit. Selection depends on assembly process requirements and inventory management preferences.
