Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RN55C1001FR36 is determined by the following criteria:

Primary Compatibility Parameters:

• Resistance value: 1 kOhms (exact match required)
• Power rating: 0.125W (1/8W) (exact match required)
• Package type: Axial (exact match required)
• Physical dimensions: 0.090" Dia x 6.10mm L (exact match required)
• Composition: Metal Film (exact match required)
• Series: RN55 military series (exact match required)
• Operating temperature range: -65°C to 175°C (exact match required)

Secondary Compatibility Parameters:

• Tolerance: ±1% or tighter (±0.1% acceptable as upgrade)
• Temperature coefficient: ±50ppm/°C or better (±25ppm/°C acceptable as upgrade)
• Packaging format: Tape & Reel (TR), Bulk, or Cut Tape (CT) (interchangeable)

All substitute parts maintain identical electrical performance within the specified operating conditions and meet the same military and safety standards as the main part.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Identical Specifications): RN55C1001FRE6 is a parametric equivalent to RN55C1001FR36, differing only in packaging format (Cut Tape vs. Tape & Reel). This part maintains identical electrical characteristics and temperature coefficient performance.

Upgraded Substitutes (Enhanced Tolerance): RN55E1001BB14 and RN55E1001BRE6 provide tighter tolerance (±0.1% vs. ±1%) and improved temperature coefficient (±25ppm/°C vs. ±50ppm/°C). These upgrades are electrically compatible and suitable for applications requiring higher precision. Packaging differs (Bulk and Cut Tape respectively).

Upgraded Substitutes (Improved Temperature Coefficient): RN55E1001FB14 maintains the ±1% tolerance of the original part while offering improved temperature coefficient (±25ppm/°C vs. ±50ppm/°C). Available in Bulk packaging.

All substitute parts are active products manufactured by Vishay Dale within the RN55 military series, maintaining compliance with MIL-R-10509/7 specifications and identical RoHS and REACH status.

Frequently Asked Questions (FAQ)

Q: Can RN55C1001FRE6 be used as a direct replacement for RN55C1001FR36? A: Yes. RN55C1001FRE6 is electrically and mechanically identical to RN55C1001FR36. The only difference is packaging format (Cut Tape vs. Tape & Reel). Both parts have identical resistance, tolerance, power rating, temperature coefficient, and operating temperature range.

Q: What is the difference between the RN55E series and RN55C series parts? A: The RN55E series parts (RN55E1001BB14, RN55E1001BRE6, RN55E1001FB14) offer improved specifications compared to the RN55C series. RN55E parts feature tighter tolerance (±0.1%) and lower temperature coefficient (±25ppm/°C), providing enhanced precision and stability. All parts remain within the military RN55 series.

Q: Are the substitute parts compatible with the same circuit board layout? A: Yes. All substitute parts maintain identical axial package dimensions (0.090" Dia x 0.240" L / 2.29mm x 6.10mm) and two-termination configuration. No PCB layout modifications are required.

Q: Does packaging format affect electrical performance? A: No. Tape & Reel (TR), Bulk, and Cut Tape (CT) packaging formats are distribution methods only and do not affect electrical characteristics, performance, or reliability of the resistor.

Q: Can RN55E1001BB14 or RN55E1001BRE6 be used in place of RN55C1001FR36? A: Yes. These parts are electrically compatible upgrades with superior tolerance and temperature coefficient specifications. They are suitable for applications where the original part is specified, with the added benefit of tighter tolerance and improved thermal stability.

Q: What inventory considerations should guide part selection? A: RN55C1001FRE6 has the highest inventory (4070 Pcs), followed by RN55E1001BB14 (1881 Pcs). If packaging format is not a constraint, RN55C1001FRE6 provides the best availability while maintaining identical electrical specifications to the original part.
