Key Parameters

Substitute Part Grouping Explanation

Substitution of RN55C1002FRSL is determined by the following critical parameters: resistance value (10 kOhms), power rating (0.125W), package type (axial), physical dimensions (0.090" Dia x 0.240" L), operating temperature range (-65°C ~ 175°C), and series compliance (MIL-R-10509/7, RN55). All identified substitutes maintain these core electrical and mechanical specifications.

Substitutes are categorized into two groups:

Upgrade Substitutes feature improved tolerance (±0.1% versus ±1%) and lower temperature coefficient (±25ppm/°C versus ±50ppm/°C), providing enhanced precision and stability. These parts are electrically and mechanically interchangeable with the main part while offering superior performance characteristics. Packaging formats vary (Bulk or Cut Tape) to accommodate different procurement and assembly workflows.

Parametric Equivalent maintains identical tolerance (±1%) and temperature coefficient (±50ppm/°C) as the main part, differing only in packaging format (Cut Tape versus Tape & Reel), ensuring direct functional equivalence with alternative supply chain options.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain active product status and comply with MIL-R-10509/7 military specifications. Selection between substitutes is based on application requirements and supply chain considerations:

For applications requiring enhanced precision and thermal stability, RN55E1002BB14 (Bulk) and RN55E1002BRE6 (Cut Tape) provide ±0.1% tolerance and ±25ppm/°C temperature coefficient. These upgrade substitutes are suitable for precision analog circuits and measurement applications where tighter tolerance and lower drift are critical.

For applications where the original ±1% tolerance and ±50ppm/°C temperature coefficient are acceptable, RN55E1002FB14 (Bulk), RN55E1002FRE6 (Cut Tape), and RN55C1002FRE6 (Cut Tape) provide direct functional equivalence. RN55C1002FRE6 is the parametric equivalent with identical electrical characteristics to the main part, differing only in packaging format.

Packaging format selection depends on assembly process requirements: Tape & Reel (TR) and Cut Tape (CT) formats support automated pick-and-place assembly, while Bulk packaging accommodates manual assembly or alternative handling workflows.

Frequently Asked Questions (FAQ)

Q: Can RN55E1002BB14 and RN55E1002BRE6 be used interchangeably with RN55C1002FRSL?

A: Yes. Both parts are electrically and mechanically interchangeable. They maintain identical resistance (10 kOhms), power rating (0.125W), package type (axial), and physical dimensions. The primary differences are improved tolerance (±0.1% versus ±1%) and lower temperature coefficient (±25ppm/°C versus ±50ppm/°C), which represent performance enhancements rather than incompatibilities.

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

A: Tape & Reel (TR) format supplies components on continuous carrier tape wound on reels, optimized for high-volume automated assembly. Cut Tape (CT) format provides components on cut sections of carrier tape, suitable for moderate-volume production or mixed-component assembly. Bulk packaging supplies loose components, typically used for manual assembly or low-volume applications. All three formats contain identical components; packaging selection depends on assembly equipment and production volume.

Q: Is RN55C1002FRE6 a direct replacement for RN55C1002FRSL?

A: RN55C1002FRE6 is a parametric equivalent with identical electrical specifications (10 kOhms, ±1% tolerance, ±50ppm/°C temperature coefficient). The difference is packaging format: RN55C1002FRSL is supplied in Tape & Reel format with 902 units in stock, while RN55C1002FRE6 is supplied in Cut Tape format with 6644 units in stock. Both are functionally equivalent for circuit applications.

Q: Which substitute should I select for precision applications?

A: For precision applications requiring tighter tolerance and lower thermal drift, select RN55E1002BB14 or RN55E1002BRE6. Both offer ±0.1% tolerance and ±25ppm/°C temperature coefficient, compared to the main part's ±1% tolerance and ±50ppm/°C coefficient. Choose between Bulk (BB14) or Cut Tape (BRE6) format based on assembly requirements.

Q: Are all substitutes compliant with MIL-R-10509/7?

A: Yes. All listed substitutes are part of the military-grade RN55 series and comply with MIL-R-10509/7 specifications. All parts feature flame retardant coating, moisture resistance, and safety certification, maintaining military-specification performance across the entire substitute group.
