• Tolerance: ±1% (exact match required)
• Power rating: 0.25W / 1/4W (exact match required)
• Composition: Metal Film (exact match required)
• Package configuration: Axial through-hole (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C to 155°C (exact match required)
• Physical dimensions: 0.093" Dia × 0.250" L (exact match required)
• Regulatory compliance: ROHS3 Compliant (exact match required)

The identified substitute part RNF14FTD4M75 meets all specified parameters and is manufactured by the same supplier, ensuring direct functional and mechanical interchangeability.

Parameter Comparison

Engineering Selection Recommendations

Both RNF14FAD4M75 and RNF14FTD4M75 are Active products manufactured by Stackpole Electronics Inc within the RNF series. Both components maintain ROHS3 compliance and identical electrical, mechanical, and thermal specifications. Selection between these parts should be based on procurement factors such as inventory availability, lead time, and supply chain requirements. The RNF14FTD4M75 currently maintains higher inventory levels (12745 units versus 3005 units), which may provide supply chain advantages for high-volume applications or extended production schedules.

Frequently Asked Questions (FAQ)

Q: Can RNF14FTD4M75 be used as a direct replacement for RNF14FAD4M75?

A: Yes. Both parts are electrically and mechanically identical, with matching resistance values (4.75 MOhms), tolerance (±1%), power rating (0.25W), composition (metal film), package type (axial), temperature specifications, and physical dimensions. Both are ROHS3 compliant and manufactured by Stackpole Electronics Inc.

Q: Are there any differences in performance or reliability between these two part numbers?

A: No. The specifications provided indicate identical performance characteristics, including temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and safety features (flame retardant coating).

Q: What determines whether a part can substitute for the RNF14FAD4M75?

A: Substitution requires exact matching of resistance value, tolerance, power rating, composition, package configuration, temperature coefficient, operating temperature range, physical dimensions, and regulatory compliance status. Any deviation in these parameters disqualifies a part from direct substitution.

Q: Does the packaging format (Cut Tape) affect substitution eligibility?

A: Packaging format relates to supply and handling but does not affect electrical or mechanical interchangeability. Both parts are supplied in Cut Tape (CT) format.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts maintain identical RoHS3 compliance, REACH Unaffected status, and EAR99 ECCN classification.
