Key Parameters

Substitute Part Grouping Explanation

The RN60D3900FB14 qualifies as a direct substitute for the RN60D3900FRE6 based on the following criteria:

Identical Electrical Parameters:

• Resistance value: 390 Ohms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -65°C to 175°C

Identical Mechanical Parameters:

• Composition: Metal Film
• Package type: Axial
• Physical dimensions: 0.145" Dia x 0.344" L (3.68mm x 8.74mm)
• Number of terminations: 2

Identical Functional Features:

• Flame retardant coating
• Military-grade construction
• Moisture resistant
• Safety-rated design
• MIL-R-10509/1 compliance

Difference: The sole distinction between these parts is packaging format: RN60D3900FRE6 is supplied in Tape & Reel (TR) format, while RN60D3900FB14 is supplied in Bulk format. This difference affects procurement and handling but does not alter electrical or mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

Both RN60D3900FRE6 and RN60D3900FB14 are active production parts from Vishay Dale with identical electrical and mechanical specifications. Selection between these parts should be based on procurement and assembly requirements:

RN60D3900FRE6 (Tape & Reel): Suitable for automated assembly processes requiring tape-and-reel packaging. Recommended for high-volume production environments with pick-and-place equipment.

RN60D3900FB14 (Bulk): Suitable for manual assembly, repair, or lower-volume applications. Bulk packaging provides flexibility for mixed-component procurement.

Both parts maintain MIL-R-10509/1 military specification compliance and are RoHS non-compliant with REACH Affected status. Component selection does not impact circuit performance, reliability, or environmental compliance.

Frequently Asked Questions (FAQ)

Q: Can RN60D3900FB14 be used as a direct replacement for RN60D3900FRE6?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (Bulk vs. Tape & Reel). Substitution is valid for any application where the original part is specified.

Q: What is the difference between Tape & Reel and Bulk packaging?

A: Tape & Reel (TR) packaging supplies components on continuous carrier tape suitable for automated pick-and-place assembly. Bulk packaging supplies loose components in containers, suitable for manual assembly or repair work. Electrical and mechanical performance are identical.

Q: Are these parts interchangeable in military applications?

A: Yes. Both parts comply with MIL-R-10509/1 specification and carry identical military-grade certifications, features, and performance characteristics. Packaging format does not affect military compliance.

Q: What are the key parameters that determine substitution eligibility?

A: Resistance value (390 Ohms), tolerance (±1%), power rating (0.25W), composition (Metal Film), temperature coefficient (±100ppm/°C), operating temperature range (-65°C to 175°C), axial package type, and physical dimensions (0.145" Dia x 0.344" L) must all match. These parts meet all criteria.

Q: Can these parts be used in high-temperature applications?

A: Yes. Both parts are rated for operating temperatures up to 175°C, supporting high-temperature circuit applications within the specified range.

Q: What is the moisture sensitivity level for these parts?

A: Moisture Sensitivity Level (MSL) is Not Applicable for both parts, indicating no moisture-related handling restrictions during storage or assembly.
