Key Parameters

Substitute Part Grouping Explanation

The RN55E5620BB14 qualifies as a direct substitute based on the following critical parameters:

• Resistance Value: Both parts are 562 Ohms, ensuring identical electrical function
• Power Rating: Both rated at 0.125W (1/8W), supporting equivalent thermal performance
• Composition: Both are metal film construction with identical physical dimensions (0.090" Dia x 0.240" L)
• Operating Temperature Range: Both operate across -65°C to 175°C
• Military Series: Both conform to MIL-R-10509/7 specification and RN55 base product line
• Features: Both include flame retardant coating, moisture resistance, and safety rating

The primary differences are tolerance specification (±1% vs ±0.1%) and packaging format (tape and reel vs bulk), which do not prevent substitution but may affect application suitability based on circuit requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the RN55C5620FRE6 and RN55E5620BB14 are active production parts from Vishay Dale with identical military qualification and compliance status. Selection between these parts should be based on:

Tolerance Requirements: The RN55E5620BB14 offers ±0.1% tolerance compared to ±1% for the RN55C5620FRE6. Applications requiring tighter resistance tolerance should specify the RN55E5620BB14.

Temperature Stability: The RN55E5620BB14 provides superior temperature coefficient performance (±25ppm/°C vs ±50ppm/°C), resulting in better resistance stability across the -65°C to 175°C operating range.

Packaging Format: The RN55C5620FRE6 is supplied in tape and reel format suitable for automated assembly. The RN55E5620BB14 is supplied in bulk format, appropriate for manual assembly or alternative handling requirements.

Compliance: Both parts maintain identical RoHS non-compliant and REACH Affected status, ensuring consistent regulatory treatment in supply chain documentation.

Frequently Asked Questions (FAQ)

Q: Can RN55E5620BB14 replace RN55C5620FRE6 in existing designs?

A: Yes. Both parts share identical resistance value (562 Ohms), power rating (0.125W), physical dimensions (0.090" Dia x 0.240" L), operating temperature range (-65°C to 175°C), and military series qualification (MIL-R-10509/7). The RN55E5620BB14 provides improved tolerance (±0.1% vs ±1%) and temperature coefficient (±25ppm/°C vs ±50ppm/°C), making it functionally superior for direct substitution.

Q: What are the differences in packaging between these parts?

A: The RN55C5620FRE6 is supplied in tape and reel (TR) format, optimized for automated pick-and-place assembly. The RN55E5620BB14 is supplied in bulk format, suitable for manual assembly or alternative handling processes. Both use identical axial package construction with no dimensional differences.

Q: Are there tolerance implications for circuit design?

A: The RN55E5620BB14 tolerance of ±0.1% is tighter than the RN55C5620FRE6 tolerance of ±1%. In circuits where resistance tolerance directly affects performance (precision filters, reference networks, or calibrated dividers), the RN55E5620BB14 provides superior accuracy. For general-purpose applications, both tolerances are functionally equivalent.

Q: Do these parts have identical temperature stability?

A: No. The RN55E5620BB14 has a temperature coefficient of ±25ppm/°C, while the RN55C5620FRE6 has ±50ppm/°C. Over the full operating range (-65°C to 175°C), the RN55E5620BB14 maintains tighter resistance stability. For temperature-sensitive applications, the RN55E5620BB14 is the preferred choice.

Q: Are compliance and certification identical?

A: Yes. Both parts are RoHS non-compliant and REACH Affected with identical ECCN (EAR99) and HTSUS (8533.21.0090) classifications. Both conform to MIL-R-10509/7 military specification and are part of the RN55 base product line.
