Substitute Part Grouping Explanation

Substitute parts for the RN65D4992FRE6 are identified based on strict electrical and mechanical parameter matching within the RN65 military series. The substitution criteria are:

• Identical resistance value: 49.9 kOhms
• Identical tolerance: ±1%
• Identical power rating: 0.5W (1/2W)
• Identical composition: Metal Film
• Identical package type: Axial
• Identical temperature coefficient: ±100ppm/°C
• Identical operating temperature range: -65°C to 175°C
• Identical physical dimensions: 0.180" Dia x 0.562" L
• Same military series designation: RN65, MIL-R-10509/2
• Identical feature set: Flame Retardant Coating, Military, Moisture Resistant, Safety

The primary difference between the main part and its substitute is the packaging format: the main part is supplied in Tape & Reel (TR) configuration, while the substitute is supplied in Bulk packaging. Both parts maintain identical electrical performance and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the RN65D4992FRE6 and RN65D4992FB14 are active products from Vishay Dale with identical electrical specifications and mechanical dimensions. Selection between these parts should be based on procurement and assembly requirements:

The RN65D4992FRE6 in Tape & Reel packaging is suitable for automated assembly processes and high-volume production environments where component feeding systems require standardized reel formats.

The RN65D4992FB14 in Bulk packaging is suitable for manual assembly, low-volume production, repair operations, and applications where reel-based handling is not required.

Both parts maintain identical compliance status: RoHS non-compliant and REACH Affected. No electrical or thermal performance differences exist between these substitutes. The choice between them is determined solely by packaging and handling requirements for the specific application or manufacturing process.

Frequently Asked Questions (FAQ)

Q: Can RN65D4992FB14 be used as a direct replacement for RN65D4992FRE6 in circuit design?

A: Yes. Both parts have identical electrical specifications, including resistance value, tolerance, power rating, temperature coefficient, and operating temperature range. They are mechanically compatible with identical axial package dimensions. The only difference is packaging format (Tape & Reel versus Bulk).

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

A: Tape & Reel (TR) packaging supplies components on continuous carrier tape wound on reels, designed for automated pick-and-place assembly equipment. Bulk packaging supplies loose components in bags or trays, suitable for manual assembly or applications not requiring automated feeding systems.

Q: Are there any performance differences between these substitute parts?

A: No. Both parts are manufactured by Vishay Dale within the same RN65 military series and meet identical MIL-R-10509/2 specifications. Electrical performance, thermal characteristics, and reliability are equivalent.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both RN65D4992FRE6 and RN65D4992FB14 share identical RoHS and REACH compliance status. Both are RoHS non-compliant and REACH Affected.

Q: Can I mix these parts in the same assembly?

A: Yes. Since both parts are electrically and mechanically identical, they can be used interchangeably within the same circuit board assembly. Packaging format does not affect circuit performance.

Q: What determines whether a part qualifies as a substitute?

A: For the RN65 military resistor series, substitutes must match all electrical parameters (resistance, tolerance, power rating, temperature coefficient, operating temperature range), composition (metal film), package type (axial), physical dimensions, and feature set (flame retardant coating, military grade, moisture resistant, safety rated).
