Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RN55E1001FRE6 is determined by the following criteria:

Electrical Parameters (Must Match):

• Resistance value: 1 kOhms
• Power rating: 0.125W (1/8W)
• Composition: Metal Film
• Temperature coefficient: ±25ppm/°C
• Operating temperature range: -65°C to 175°C
• Series compliance: MIL-R-10509/7, RN55

Tolerance Compatibility:

• Direct substitutes maintain ±1% tolerance
• Upgrade substitutes offer improved ±0.1% tolerance while maintaining all other electrical specifications

Packaging Variations:

• RN55E1001FRE6: Tape & Reel (TR)
• RN55E1001FB14: Bulk packaging
• RN55E1001BB14: Bulk packaging
• RN55E1001BRE6: Cut Tape (CT) packaging

All substitute parts share identical mechanical dimensions, termination count (2), and feature set. Packaging differences do not affect electrical performance or physical fit.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Same Tolerance): RN55E1001FB14 is a direct electrical equivalent to RN55E1001FRE6, maintaining ±1% tolerance and identical electrical specifications. Selection between these two parts depends on packaging requirements: RN55E1001FRE6 is supplied in Tape & Reel format suitable for automated assembly, while RN55E1001FB14 is supplied in Bulk format for manual handling or smaller quantity applications.

Upgrade Options (Improved Tolerance): RN55E1001BB14 and RN55E1001BRE6 both offer ±0.1% tolerance, providing superior accuracy compared to the ±1% specification of RN55E1001FRE6. These upgrades maintain all other electrical and mechanical parameters. RN55E1001BB14 is available in Bulk packaging with highest inventory (1881 units), while RN55E1001BRE6 is supplied in Cut Tape format with 1091 units in stock.

All substitute parts maintain active product status, military series compliance (MIL-R-10509/7, RN55), and identical operating temperature range (-65°C to 175°C). Selection should be based on packaging format requirements and tolerance specifications needed for the application.

Frequently Asked Questions (FAQ)

Q: Can RN55E1001FB14 replace RN55E1001FRE6 in production assembly? A: Yes. RN55E1001FB14 is electrically identical with matching ±1% tolerance, resistance value, power rating, and temperature specifications. The difference is packaging format: RN55E1001FRE6 uses Tape & Reel for automated pick-and-place equipment, while RN55E1001FB14 uses Bulk packaging. Assembly method compatibility must be confirmed based on your equipment capabilities.

Q: What is the advantage of upgrading to RN55E1001BB14 or RN55E1001BRE6? A: Both upgrade parts provide ±0.1% tolerance instead of ±1%, delivering tighter resistance accuracy. All other specifications remain identical: same 1 kOhms resistance, 0.125W power rating, metal film composition, temperature coefficient, and operating range. Upgrade selection depends on circuit accuracy requirements and packaging preference (Bulk vs. Cut Tape).

Q: Are all substitute parts MIL-R-10509/7 compliant? A: Yes. RN55E1001FRE6, RN55E1001FB14, RN55E1001BB14, and RN55E1001BRE6 are all part of the military-grade RN55 series and comply with MIL-R-10509/7 specifications. All feature flame retardant coating, moisture resistance, and safety-rated construction.

Q: Do packaging differences affect electrical performance? A: No. Tape & Reel (TR), Bulk, and Cut Tape (CT) packaging formats do not affect electrical characteristics or physical dimensions. Packaging selection is based on assembly process requirements and quantity handling preferences.

Q: What is the physical compatibility between substitute parts? A: All substitute parts share identical axial package dimensions (0.090" Dia x 0.240" L / 2.29mm x 6.10mm) and two-termination configuration. They are mechanically interchangeable in PCB layouts and through-hole applications.
