Key Parameters

Substitute Part Grouping Explanation

The RN55E1004BB14 qualifies as a direct substitute based on the following alignment of critical parameters:

• Identical resistance value: 1 MOhms
• Identical power rating: 0.125W (1/8W)
• Identical package type: Axial
• Identical physical dimensions: 0.090" Dia x 0.240" L (2.29mm x 6.10mm)
• Identical operating temperature range: -65°C to 175°C
• Identical series classification: Military, MIL-R-10509/7, RN55
• Identical composition: Metal Film
• Identical features: Flame Retardant Coating, Military, Moisture Resistant, Safety

The substitute part offers improved tolerance (±0.1% versus ±1%) and lower temperature coefficient (±25ppm/°C versus ±50ppm/°C), representing an upgrade in precision characteristics. Packaging differs (Bulk versus Cut Tape), which affects procurement and handling but not electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the RN55C1004FRE6 and RN55E1004BB14 maintain active product status and identical compliance classifications (RoHS non-compliant, REACH Affected). Selection between these parts depends on application tolerance requirements and procurement format:

The RN55C1004FRE6 is suitable for applications where ±1% tolerance meets circuit specifications and Cut Tape packaging aligns with assembly processes.

The RN55E1004BB14 is appropriate for applications requiring tighter tolerance control (±0.1%) and lower temperature coefficient drift (±25ppm/°C versus ±50ppm/°C), with Bulk packaging for high-volume procurement scenarios.

Both parts satisfy military-grade specifications per MIL-R-10509/7 and maintain identical thermal and mechanical performance across the -65°C to 175°C operating range.

Frequently Asked Questions (FAQ)

Q: Can RN55E1004BB14 directly replace RN55C1004FRE6 in existing designs?

A: Yes. Both parts share identical resistance, power rating, package type, physical dimensions, operating temperature range, and series classification. The substitute offers improved tolerance and temperature coefficient characteristics.

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

A: The RN55E1004BB14 provides ±0.1% tolerance compared to ±1% in the RN55C1004FRE6, and features a lower temperature coefficient (±25ppm/°C versus ±50ppm/°C). Packaging differs: Cut Tape versus Bulk.
