Substitute Part Grouping Explanation

Substitution of the RN65C1502FBSL is permissible with the RN70C1502FB14 based on the following criteria:

Matching Parameters (Substitution Basis):

• Resistance value: 15 kOhms (identical)
• Tolerance: ±1% (identical)
• Composition: Metal Film (identical)
• Temperature Coefficient: ±50ppm/°C (identical)
• Operating Temperature Range: -65°C to 175°C (identical)
• Package Type: Axial (identical)
• Features: Flame Retardant Coating, Military, Moisture Resistant, Safety (identical)
• Physical Dimensions: 0.180" Dia x 0.562" L (4.57mm x 14.27mm) (identical)

Differing Parameter (Upgrade Characteristic):

• Power Rating: RN70C1502FB14 is rated at 0.75W (3/4W) versus the RN65C1502FBSL at 0.5W (1/2W)

The RN70C1502FB14 represents an upgrade path for applications requiring higher power dissipation while maintaining all other electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the RN65C1502FBSL and RN70C1502FB14 are active products manufactured by Vishay Dale with identical compliance profiles. Selection between these parts depends on circuit power dissipation requirements:

• RN65C1502FBSL (0.5W): Select for applications where the calculated power dissipation does not exceed 0.5W at maximum operating temperature.
• RN70C1502FB14 (0.75W): Select for applications where power dissipation ranges from 0.5W to 0.75W, or where thermal margin is required for reliability in military or high-reliability environments.

Both parts maintain identical electrical characteristics (resistance, tolerance, temperature coefficient) and mechanical compatibility (axial package, identical physical dimensions). The RoHS non-compliant and REACH Affected status applies uniformly to both parts.

Frequently Asked Questions (FAQ)

Q: Can RN70C1502FB14 directly replace RN65C1502FBSL in existing designs?

A: Yes. The RN70C1502FB14 is mechanically and electrically compatible. Both parts feature identical axial package dimensions (0.180" Dia x 0.562" L), resistance value (15 kOhms), tolerance (±1%), and temperature characteristics. The higher power rating of the RN70C1502FB14 does not create compatibility issues in circuits designed for the RN65C1502FBSL.

Q: What is the primary difference between these two parts?

A: The power rating differs. RN65C1502FBSL is rated at 0.5W, while RN70C1502FB14 is rated at 0.75W. All other specifications—resistance, tolerance, temperature coefficient, operating range, and package type—are identical.

Q: Are there any compliance or certification differences?

A: No. Both parts share identical RoHS non-compliant and REACH Affected status. Both comply with military specifications (MIL-R-10509) and feature identical flame retardant coating, moisture resistance, and safety characteristics.

Q: Which part should be selected for new designs?

A: Selection depends on calculated power dissipation. If dissipation remains below 0.5W, either part is acceptable. For dissipation between 0.5W and 0.75W, or for designs requiring thermal margin, the RN70C1502FB14 is appropriate.

Q: Are the physical dimensions identical?

A: Yes. Both parts measure 0.180" Dia x 0.562" L (4.57mm x 14.27mm) and use axial package configuration, ensuring identical PCB footprint and mounting compatibility.
