Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RN55E1500FRE6 is determined by the following critical parameters:

• Resistance value: 150 Ohms (exact match required)
• Power rating: 0.125W, 1/8W (exact match required)
• Composition: Metal Film (exact match required)
• Package type: Axial (exact match required)
• Physical dimensions: 0.090" Dia × 0.240" L (exact match required)
• Temperature coefficient: ±25ppm/°C (exact match required)
• Operating temperature range: -65°C to 175°C (exact match required)
• Series compliance: MIL-R-10509/7, RN55 (exact match required)

The identified substitute part RN55E1500BB14 meets all critical electrical and mechanical parameters. The primary difference is tolerance specification (±0.1% versus ±1%) and packaging format (Bulk versus Tape & Reel). Tolerance tightening represents an upgrade path and does not preclude substitution in applications where the original tolerance is acceptable.

Parameter Comparison

Engineering Selection Recommendations

Both RN55E1500FRE6 and RN55E1500BB14 are active production parts manufactured by Vishay Dale to identical military specifications (MIL-R-10509/7). Both components maintain RoHS non-compliant and REACH Affected status, indicating equivalent regulatory positioning.

The RN55E1500BB14 offers tighter tolerance specification (±0.1% versus ±1%), which provides improved accuracy without compromising any electrical or mechanical characteristics. This represents a direct upgrade path where tolerance requirements permit.

Packaging format differs between the two parts: RN55E1500FRE6 is supplied in Tape & Reel format suitable for automated assembly, while RN55E1500BB14 is supplied in Bulk format. Selection between these formats depends on assembly methodology and procurement requirements rather than functional performance.

Frequently Asked Questions (FAQ)

Q: Can RN55E1500BB14 be used as a direct replacement for RN55E1500FRE6?

A: Yes. Both parts are electrically and mechanically identical across all critical parameters: 150 Ohm resistance, 0.125W power rating, metal film composition, axial package, identical physical dimensions, and MIL-R-10509/7 military specification compliance. The RN55E1500BB14 features improved tolerance (±0.1% versus ±1%), which does not preclude substitution.

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

A: The primary differences are tolerance specification and packaging format. RN55E1500BB14 provides ±0.1% tolerance compared to ±1% for RN55E1500FRE6, and is supplied in Bulk packaging rather than Tape & Reel format.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both parts share identical RoHS non-compliant and REACH Affected status. Regulatory positioning is equivalent.

Q: Does the tighter tolerance of RN55E1500BB14 affect circuit performance?

A: Tighter tolerance improves measurement accuracy and reduces resistance variation across the production batch. This does not negatively impact any circuit function and may improve performance in precision applications.

Q: Which packaging format should I select?

A: Tape & Reel (RN55E1500FRE6) is standard for automated pick-and-place assembly. Bulk packaging (RN55E1500BB14) is suitable for manual assembly or applications where tape format is not required. Selection depends on assembly process and handling requirements.

Q: Are both parts currently available?

A: Yes. RN55E1500FRE6 has 799 units in stock, and RN55E1500BB14 has 1769 units in stock, both listed as new original inventory.
