Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RN55E7500FRE6 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
• Physical Dimensions: Must be 0.090" Dia × 0.240" L
• Temperature Coefficient: Must be ±25ppm/°C
• Operating Temperature Range: Must be -65°C to 175°C
• Series Compliance: Must conform to MIL-R-10509/7 and RN55 base product specifications

The RN55E7500BB14 qualifies as a substitute part. While it differs in tolerance specification (±0.1% versus ±1%) and packaging format (Bulk versus Tape & Reel), all core electrical parameters, physical dimensions, temperature characteristics, and military series compliance remain identical. The tighter tolerance of the substitute part represents an upgrade in precision capability.

Parameter Comparison

Engineering Selection Recommendations

Both RN55E7500FRE6 and RN55E7500BB14 maintain active product status and comply with military specifications per MIL-R-10509/7. Selection between these parts should be based on:

RN55E7500FRE6 is appropriate when tape and reel packaging is required for automated assembly processes or when standard ±1% tolerance meets circuit requirements.

RN55E7500BB14 is appropriate when bulk packaging is acceptable and the tighter ±0.1% tolerance specification provides improved precision for precision analog circuits or measurement applications. The enhanced tolerance does not compromise any electrical or thermal characteristics.

Both parts are RoHS non-compliant and REACH Affected, with identical compliance status. No performance degradation occurs when substituting between these parts within their specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can RN55E7500BB14 be used as a direct replacement for RN55E7500FRE6?

A: Yes. All electrical parameters, physical dimensions, temperature characteristics, and military series compliance are identical. The substitute part features tighter tolerance (±0.1% versus ±1%), which represents an upgrade in precision capability without introducing any compatibility issues.

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

A: The primary differences are packaging format (Tape & Reel versus Bulk) and tolerance specification (±1% versus ±0.1%). All core electrical and mechanical parameters remain identical.

Q: Are the physical dimensions identical?

A: Yes. Both parts measure 0.090" Dia × 0.240" L (2.29mm × 6.10mm) and are housed in identical axial packages. They are mechanically interchangeable.

Q: Do both parts meet military specifications?

A: Yes. Both RN55E7500FRE6 and RN55E7500BB14 conform to MIL-R-10509/7 and are part of the RN55 military series with identical flame retardant coating, moisture resistance, and safety features.

Q: What is the temperature operating range for both parts?

A: Both parts operate across -65°C to 175°C with a temperature coefficient of ±25ppm/°C.

Q: Which part should be selected for automated assembly?

A: RN55E7500FRE6 in Tape & Reel packaging is optimized for automated pick-and-place assembly processes. RN55E7500BB14 in Bulk packaging is suitable for manual assembly or when tape and reel format is not required.
