Substitute Part Grouping Explanation

Substitution eligibility for the RN55C3000BRE6 is determined by the following critical parameters:

• Resistance value: 300 Ohms (exact match required)
• Tolerance: ±0.1% (exact match required)
• Power rating: 0.125W / 1/8W (exact match required)
• Composition: Metal Film (exact match required)
• Package type: Axial (exact match required)
• Operating temperature range: -65°C to 175°C (exact match required)
• Physical dimensions: 0.090" Dia x 0.240" L (exact match required)
• Military series compliance: MIL-R-10509/7, RN55 (exact match required)

The identified substitute part RN55E3000BB14 meets all critical electrical and mechanical parameters. The primary difference is the packaging format (Bulk versus Tape & Reel) and temperature coefficient specification, which do not affect functional substitution in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the RN55C3000BRE6 and RN55E3000BB14 are active production parts from Vishay Dale with identical electrical specifications and military qualification. Selection between these parts is determined by packaging requirements:

• RN55C3000BRE6 is supplied in Tape & Reel format, suitable for automated assembly processes
• RN55E3000BB14 is supplied in Bulk format, suitable for manual assembly or alternative handling requirements

Both parts maintain identical RoHS non-compliant and REACH Affected compliance status. The temperature coefficient difference (±50ppm/°C versus ±25ppm/°C) reflects manufacturing variation within the RN55 series but does not affect substitution eligibility for standard circuit applications.

Frequently Asked Questions (FAQ)

Q: Can RN55E3000BB14 replace RN55C3000BRE6 in circuit applications?

A: Yes. Both parts are electrically and mechanically identical with 300 Ohm resistance, ±0.1% tolerance, 0.125W power rating, and identical physical dimensions. The difference is packaging format only.

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

A: The RN55C3000BRE6 is packaged in Tape & Reel format for automated assembly, while the RN55E3000BB14 is packaged in Bulk format. Electrical performance is identical.

Q: Are both parts military-qualified?

A: Yes. Both parts comply with MIL-R-10509/7 specification and are part of the RN55 military resistor series.

Q: Does the temperature coefficient difference affect substitution?

A: No. The temperature coefficient difference (±50ppm/°C versus ±25ppm/°C) represents normal manufacturing variation within the RN55 series specification and does not prevent functional substitution.

Q: What are the compliance considerations?

A: Both parts are RoHS non-compliant and REACH Affected. Compliance requirements must be evaluated based on end-application regulations.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes, provided the assembly process accommodates the packaging format. Tape & Reel format (RN55C3000BRE6) is optimized for automated pick-and-place equipment, while Bulk format (RN55E3000BB14) requires manual handling or alternative feeder systems.
