Substitute Part Grouping Explanation

The RN55E2001BB14 qualifies as a direct substitute based on the following critical parameters:

• Identical resistance value: 2 kOhms
• Identical power rating: 0.125W (1/8W)
• Identical composition: Metal Film
• Identical package type: Axial
• Identical physical dimensions: 0.090" Dia × 0.240" L (2.29mm × 6.10mm)
• Identical temperature coefficient: ±25ppm/°C
• Identical operating temperature range: -65°C to 175°C
• Identical series classification: RN55 (MIL-R-10509/7)
• Identical features: Flame Retardant Coating, Military Grade, Moisture Resistant, Safety Certified

The primary difference is packaging format (Tape & Reel versus Bulk) and tolerance specification (±1% versus ±0.1%). The tighter tolerance of the substitute part represents an upgrade in precision capability.

Parameter Comparison

Engineering Selection Recommendations

Both RN55E2001FRE6 and RN55E2001BB14 are active production components from Vishay Dale's military-grade RN55 series. Selection between these parts should be based on:

• Packaging format requirement: RN55E2001FRE6 is supplied in Tape & Reel format suitable for automated assembly; RN55E2001BB14 is supplied in Bulk format suitable for manual assembly or small-quantity applications.
• Tolerance specification: RN55E2001BB14 offers ±0.1% tolerance compared to ±1% for RN55E2001FRE6, providing superior precision for applications requiring tighter resistance values.
• Inventory availability: RN55E2001BB14 has higher stock levels (936 units versus 651 units).

Both parts maintain identical electrical performance, thermal characteristics, and military-grade certifications. Physical dimensions and mounting compatibility are identical, ensuring direct functional interchangeability in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can RN55E2001BB14 be used as a direct replacement for RN55E2001FRE6?

A: Yes. Both parts share identical electrical specifications (2 kOhms, 0.125W, metal film composition), physical dimensions (0.090" Dia × 0.240" L), and operating characteristics (-65°C to 175°C). The RN55E2001BB14 provides tighter tolerance (±0.1% versus ±1%), making it functionally compatible and electrically superior for most applications.

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

A: Tape & Reel (TR) packaging is designed for automated pick-and-place assembly equipment in high-volume manufacturing. Bulk packaging is supplied as loose components suitable for manual assembly, prototyping, or low-volume production. Both formats contain identical components with no electrical or performance differences.

Q: Are both parts RoHS compliant?

A: Both RN55E2001FRE6 and RN55E2001BB14 are RoHS non-compliant. They are military-grade components manufactured to MIL-R-10509/7 specifications, which may contain materials restricted under RoHS directives. Verify compliance requirements for your specific application.

Q: What is the temperature coefficient significance?

A: Both parts have a temperature coefficient of ±25ppm/°C, meaning the resistance value changes by a maximum of 25 parts per million for each degree Celsius change in operating temperature. This specification is identical between both parts and suitable for military and high-reliability applications operating across the -65°C to 175°C range.

Q: Can I substitute based on tolerance alone?

A: The RN55E2001BB14 with ±0.1% tolerance is a precision upgrade over the ±1% tolerance of RN55E2001FRE6. If your circuit design requires ±1% tolerance, both parts are acceptable. If tighter tolerance is required, RN55E2001BB14 is the appropriate selection. Tolerance cannot be downgraded (using a ±1% part where ±0.1% is required).
