Substitute Part Grouping Explanation

Substitution eligibility is determined by three core criteria: resistance value, power rating, and package type. All identified substitutes maintain the 1 kOhms resistance and 0.125W power rating required for direct functional replacement. Substitutes are categorized as follows:

Upgrade Substitutes (RN55E1001BB14, RN55E1001BRE6, RN55E1001FB14): These parts offer improved tolerance specifications (±0.1% versus ±1%) and reduced temperature coefficient (±25ppm/°C versus ±50ppm/°C), providing enhanced precision and stability. They are available in Bulk and Cut Tape packaging formats.

Parametric Equivalent (RN55C1001FRE6): This part matches the original tolerance (±1%) and temperature coefficient (±50ppm/°C) specifications but differs in packaging format (Cut Tape versus Tape & Reel).

All substitutes share identical resistance, power rating, composition, operating temperature range, and military-grade certifications with the main part.

Parameter Comparison

Engineering Selection Recommendations

Selection among equivalent and substitute parts is determined by packaging requirements and tolerance specifications:

For Tape & Reel applications requiring ±1% tolerance and ±50ppm/°C temperature coefficient: RN55C1001FRE6 provides parametric equivalence with Cut Tape packaging as an alternative.

For applications requiring improved tolerance (±0.1%) and reduced temperature coefficient (±25ppm/°C): RN55E1001BB14 (Bulk), RN55E1001BRE6 (Cut Tape), and RN55E1001FB14 (Bulk) are direct upgrades. RN55E1001FB14 maintains the original ±1% tolerance while offering improved temperature coefficient performance.

For packaging format flexibility: RN55E1001BRE6 and RN55C1001FRE6 are available in Cut Tape format; RN55E1001BB14 and RN55E1001FB14 are available in Bulk format.

All parts maintain active product status, military-grade certifications, and identical operating temperature range (-65°C to 175°C). RoHS non-compliance and REACH Affected status are consistent across all parts.

Frequently Asked Questions (FAQ)

Q: Can RN55E1001BB14 directly replace RN55C1001FRSL?

A: Yes. RN55E1001BB14 is functionally compatible as a direct replacement. It maintains identical resistance (1 kOhms) and power rating (0.125W). The improved tolerance (±0.1% versus ±1%) and reduced temperature coefficient (±25ppm/°C versus ±50ppm/°C) represent performance enhancements. Packaging differs (Bulk versus Tape & Reel).

Q: What is the difference between upgrade substitutes and parametric equivalents?

A: Upgrade substitutes (RN55E1001BB14, RN55E1001BRE6, RN55E1001FB14) offer improved electrical specifications, particularly tolerance and temperature coefficient. Parametric equivalents (RN55C1001FRE6) match the original electrical specifications but differ in packaging format.

Q: Are all substitutes available in the same packaging format as the original part?

A: No. The original RN55C1001FRSL is supplied in Tape & Reel format. Substitutes are available in Bulk and Cut Tape formats. RN55C1001FRE6 is the only substitute available in Cut Tape format with matching electrical specifications.

Q: Do packaging format differences affect electrical performance?

A: No. Packaging format (Tape & Reel, Bulk, Cut Tape) does not affect electrical performance. Format selection is determined by assembly process requirements and inventory management practices.

Q: Are all parts compliant with military specifications?

A: Yes. All parts are certified to MIL-R-10509/7 military specifications and feature flame retardant coating, moisture resistance, and safety certifications.
