Substitute Part Grouping Explanation

Substitution eligibility for the RN55D3012FRSL is determined by strict equivalence across the following critical parameters:

• Resistance value: 30.1 kOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Composition: Metal Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -65°C to 175°C
• Package type: Axial
• Physical dimensions: 0.090" Dia x 0.240" L (2.29mm x 6.10mm)
• Military series compliance: MIL-R-10509/7, RN55

The RN55D3012FRE6 qualifies as a parametric equivalent substitute. Both parts share identical electrical specifications, composition, temperature characteristics, and physical dimensions. The distinction between these parts is limited to packaging format: the RN55D3012FRSL is supplied in Tape & Reel (TR) configuration, while the RN55D3012FRE6 is supplied in Cut Tape (CT) configuration. This packaging difference does not affect component performance or circuit functionality.

Parameter Comparison

Engineering Selection Recommendations

Both the RN55D3012FRSL and RN55D3012FRE6 are active production components from Vishay Dale with identical electrical performance and military specification compliance. Selection between these parts should be based on packaging requirements and supply chain availability.

The RN55D3012FRSL in Tape & Reel format is suitable for high-volume automated assembly operations. The RN55D3012FRE6 in Cut Tape format accommodates lower-volume applications or manual assembly processes.

Both parts maintain RoHS non-compliant and REACH Affected status. Component selection must account for regulatory requirements applicable to the end application and geographic market.

Frequently Asked Questions (FAQ)

Q: Can RN55D3012FRE6 be used as a direct replacement for RN55D3012FRSL in circuit design?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, tolerance, power rating, temperature characteristics, and physical dimensions. The only difference is packaging format (Tape & Reel versus Cut Tape), which does not affect circuit performance.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging supplies components on continuous carrier tape wound on reels, optimized for automated pick-and-place assembly. Cut Tape (CT) packaging supplies components on tape segments cut to specific lengths, suitable for manual assembly or lower-volume production.

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

A: No. Both parts share identical RoHS status (non-compliant), REACH status (Affected), ECCN classification (EAR99), and HTSUS code (8533.21.0090). Military specification compliance (MIL-R-10509/7) is identical.

Q: What inventory levels are available for each part?

A: RN55D3012FRSL (Tape & Reel) has 729 units in stock. RN55D3012FRE6 (Cut Tape) has 1655 units in stock.

Q: Can these parts be used in military or aerospace applications?

A: Both parts comply with military specification MIL-R-10509/7 and feature military-grade construction with flame retardant coating and moisture resistance. Application suitability depends on specific system requirements and qualification documentation.
