Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RN55C7500FRE6 is determined by the following critical parameters:

• Resistance Value: Must be 750 Ohms
• Power Rating: Must be 0.125W (1/8W)
• Composition: Must be Metal Film
• Package Type: Must be Axial
• Operating Temperature Range: Must support -65°C to 175°C
• Physical Dimensions: Must be 0.090" Dia x 0.240" L (2.29mm x 6.10mm)
• Series Compliance: Must conform to MIL-R-10509/7 military specifications
• Features: Must include Flame Retardant Coating, Military rating, Moisture Resistance, and Safety construction

The RN55E7500BB14 qualifies as a substitute part. While it offers improved tolerance (±0.1% versus ±1%) and lower temperature coefficient (±25ppm/°C versus ±50ppm/°C), it maintains identical resistance, power rating, composition, package type, operating temperature range, and physical dimensions. The primary difference is packaging format (Bulk versus Tape & Reel) and enhanced electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both the RN55C7500FRE6 and RN55E7500BB14 maintain Active product status and comply with military specifications per MIL-R-10509/7. Selection between these parts should be based on the following criteria:

RN55C7500FRE6 is appropriate when Tape & Reel packaging is required for automated assembly processes or when standard ±1% tolerance meets circuit requirements.

RN55E7500BB14 is appropriate when tighter tolerance (±0.1%) and lower temperature coefficient (±25ppm/°C) are required for precision applications, or when Bulk packaging is acceptable. The improved electrical characteristics provide enhanced stability across the full operating temperature range.

Both parts share identical RoHS non-compliant status, REACH Affected designation, ECCN EAR99 classification, and HTSUS code 8533.21.0090. Physical footprint and thermal operating range are identical, ensuring direct circuit board compatibility.

Frequently Asked Questions (FAQ)

Q: Can RN55E7500BB14 be used as a direct replacement for RN55C7500FRE6?

A: Yes. Both parts have identical resistance (750 Ohms), power rating (1/8W), composition (Metal Film), package type (Axial), operating temperature range (-65°C to 175°C), and physical dimensions (0.090" Dia x 0.240" L). The substitute offers improved tolerance and temperature coefficient performance.

Q: What is the primary difference between these two parts?

A: The main differences are packaging format (Tape & Reel versus Bulk) and electrical performance characteristics. RN55E7500BB14 provides ±0.1% tolerance versus ±1%, and ±25ppm/°C temperature coefficient versus ±50ppm/°C.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain identical military series designation (MIL-R-10509/7, RN55), RoHS status, REACH status, and ECCN classification.

Q: Does the improved tolerance of RN55E7500BB14 affect circuit compatibility?

A: The tighter tolerance of RN55E7500BB14 provides enhanced precision but does not negatively impact compatibility. Circuits designed for ±1% tolerance will function correctly with ±0.1% components.

Q: Which packaging format should be selected?

A: Tape & Reel (RN55C7500FRE6) is standard for automated pick-and-place assembly. Bulk packaging (RN55E7500BB14) is suitable for manual assembly or when tape packaging is not required.
