Substitute Part Grouping Explanation

Substitute parts for RNF14FAD80K6 are categorized based on the following substitution criteria:

Direct Substitutes (Packaging Format Variation):

• RNF14FTD80K6: Identical electrical specifications and physical dimensions to the main part. Differs only in packaging format (Cut Tape vs. Tape & Box). Maintains all electrical parameters, tolerance, power rating, and temperature characteristics.

Manufacturer Recommended Substitute (Series Upgrade):

• RNMF14FTD80K6: Same electrical specifications (80.6 kOhms ±1%, 0.25W, ±100ppm/°C). Belongs to RNMF (Mini) series with reduced physical dimensions (0.070" Dia x 0.130" L vs. 0.093" Dia x 0.250" L). Packaging format is Tape & Reel. Suitable for space-constrained applications while maintaining identical electrical performance.

Performance Upgrade Substitute:

• CMF5580K600FHEB: Manufactured by Vishay Dale. Maintains identical resistance value and tolerance (80.6 kOhms ±1%). Upgraded power rating (0.5W vs. 0.25W) and extended operating temperature range (-55°C to 175°C vs. -55°C to 155°C). Improved temperature coefficient (±50ppm/°C vs. ±100ppm/°C). Includes moisture resistant feature. Packaging format is Cut Tape.

Parameter Comparison

Engineering Selection Recommendations

RNF14FTD80K6 is the direct functional equivalent for applications requiring identical electrical and mechanical specifications. Selection is appropriate when packaging format (Cut Tape) aligns with assembly process requirements. All compliance certifications and product status match the main part.

RNMF14FTD80K6 is suitable for space-constrained PCB layouts where reduced component dimensions (approximately 30% smaller) provide design advantage. Electrical performance remains identical. This selection is appropriate when board real estate optimization is a design requirement and Tape & Reel packaging format is compatible with production processes.

CMF5580K600FHEB is appropriate for applications requiring enhanced thermal performance or extended operating temperature range beyond 155°C. The upgraded power rating (0.5W vs. 0.25W) provides additional thermal margin in high-dissipation circuits. Improved temperature coefficient (±50ppm/°C) supports precision analog applications. Moisture resistant feature provides enhanced reliability in humid environments. All parts maintain ROHS3 compliance and Active product status.

Frequently Asked Questions (FAQ)

Q: Can RNF14FTD80K6 be used as a direct replacement for RNF14FAD80K6?

A: Yes. Both parts are identical in electrical specifications (80.6 kOhms ±1%, 0.25W, ±100ppm/°C) and physical dimensions (0.093" Dia x 0.250" L). The only difference is packaging format (Cut Tape vs. Tape & Box). Direct substitution is valid for all electrical and mechanical applications.

Q: What are the advantages of RNMF14FTD80K6 over the main part?

A: RNMF14FTD80K6 provides identical electrical performance with reduced physical dimensions (0.070" Dia x 0.130" L vs. 0.093" Dia x 0.250" L). This 30% size reduction is beneficial for compact PCB designs. Tape & Reel packaging format supports automated assembly processes. Electrical specifications remain unchanged.

Q: When should CMF5580K600FHEB be selected instead of RNF14FAD80K6?

A: CMF5580K600FHEB is selected when applications require: (1) extended operating temperature range to 175°C, (2) higher power dissipation capability (0.5W vs. 0.25W), (3) improved temperature stability (±50ppm/°C vs. ±100ppm/°C), or (4) moisture resistant coating for humid environments. All parts maintain ROHS3 compliance.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. RNF14FTD80K6, RNMF14FTD80K6, and CMF5580K600FHEB are all ROHS3 compliant with Active product status.

Q: What is the physical size difference between RNMF14FTD80K6 and the main part?

A: RNMF14FTD80K6 (Mini series) measures 0.070" Dia x 0.130" L (1.78mm x 3.30mm), compared to RNF14FAD80K6 at 0.093" Dia x 0.250" L (2.35mm x 6.35mm). The Mini series provides approximately 30% reduction in component volume.

Q: Can CMF5580K600FHEB be used in circuits designed for 0.25W resistors?

A: Yes. CMF5580K600FHEB has a 0.5W power rating, which exceeds the 0.25W requirement. The higher power rating provides additional thermal margin and does not create compatibility issues. All other electrical parameters (resistance, tolerance, temperature coefficient) are equivalent or superior.
