Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RNR55H3012FSRE5 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: ±50ppm/°C
• Operating temperature range: -65°C to 175°C
• Package configuration: Axial through-hole
• Physical dimensions: 0.094" Dia x 0.250" L
• Military specification compliance: MIL-PRF-55182/01
• Failure rate classification: S (0.001%)

The RNC55H3012FSRE6 qualifies as a parametric equivalent because it maintains identical electrical performance and mechanical compatibility. The primary distinction is packaging format (Cut Tape versus Tape & Reel) and the addition of weldable termination features in the substitute part.

Parameter Comparison

Engineering Selection Recommendations

Both the RNR55H3012FSRE5 and RNC55H3012FSRE6 are active production components within the Vishay Dale military resistor portfolio. Selection between these parts is based on procurement and assembly requirements rather than electrical performance differences.

The RNR55H3012FSRE5 in Tape & Reel packaging is suitable for high-volume automated assembly operations where continuous reel feeding is required. The RNC55H3012FSRE6 in Cut Tape packaging accommodates lower-volume builds, manual assembly processes, or applications requiring individual component handling. The weldable termination feature of the RNC55H3012FSRE6 provides additional process flexibility for specialized assembly methods.

Both parts maintain identical electrical specifications, temperature performance, and military compliance certifications. Neither part is RoHS compliant, consistent with military-grade component requirements. The ECCN classification (EAR99) and HTSUS code (8533.21.0090) are identical for both variants.

Frequently Asked Questions (FAQ)

Q: Can RNC55H3012FSRE6 be used as a direct replacement for RNR55H3012FSRE5 in circuit design?

A: Yes. Both parts are electrically and mechanically identical. The 30.1 kOhms resistance, ±1% tolerance, 0.125W power rating, temperature coefficient, and operating temperature range are identical. The physical dimensions and axial package configuration are the same, allowing direct substitution in PCB layouts and through-hole assembly.

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

A: Tape & Reel (TR) packaging supplies components on continuous reels suitable for automated pick-and-place assembly equipment. Cut Tape (CT) packaging provides components on tape segments, typically in quantities of 10 or 50 units per strip, suitable for manual assembly or lower-volume production runs.

Q: Does the weldable feature of RNC55H3012FSRE6 affect electrical performance?

A: No. The weldable termination is a manufacturing feature that enables alternative assembly methods such as ultrasonic or resistance welding. It does not alter the electrical characteristics, resistance value, tolerance, power rating, or temperature performance of the component.

Q: Are both parts compliant with military specifications?

A: Yes. Both the RNR55H3012FSRE5 and RNC55H3012FSRE6 comply with MIL-PRF-55182/01 military specifications. Both maintain the S-class failure rate (0.001%) and are rated for the full military temperature range of -65°C to 175°C.

Q: What is the inventory status for these parts?

A: The RNR55H3012FSRE5 has 1160 units in stock. The RNC55H3012FSRE6 has 1894 units in stock. Both are active production components available for immediate procurement.

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

A: Both parts share identical RoHS status (non-compliant), ECCN classification (EAR99), and HTSUS code (8533.21.0090). The REACH status differs: RNR55H3012FSRE5 status is not specified in the provided data, while RNC55H3012FSRE6 is REACH Affected.
