Substitute Part Grouping Explanation

Substitution eligibility for the RNC55H1003FPRSL is determined by the following criteria:

Primary Compatibility Requirements:

• Resistance value: 100 kOhms (exact match required)
• Power rating: 0.125W (1/8W) (exact match required)
• Package type: Axial (exact match required)
• Physical dimensions: 0.094" Dia x 0.250" L (exact match required)
• Composition: Metal Film (exact match required)
• Operating temperature range: -65°C to 175°C (exact match required)
• Series: RNC55 military specification (exact match required)

Allowable Variations:

• Packaging format (Tape & Reel, Bulk, Cut Tape)
• Tolerance specification (±1% or tighter, such as ±0.1%)
• Temperature coefficient (±50ppm/°C or better, such as ±25ppm/°C)
• Failure rate classification (P, R, or S ratings)

Substitute parts maintain identical electrical performance and mechanical fit while offering alternative packaging options or enhanced specifications.

Engineering Selection Recommendations

Direct Substitutes (Equivalent Specifications): RNC55H1003FRB14, RNC55H1003FSB14, and RNC55H1003FSRE6 are direct electrical equivalents to the RNC55H1003FPRSL. These parts maintain the ±1% tolerance and ±50ppm/°C temperature coefficient. Selection among these three is determined by packaging requirements: bulk format for RNC55H1003FRB14 and RNC55H1003FSB14, or cut tape format for RNC55H1003FSRE6. The improved failure rate classifications (R and S ratings) in these alternatives provide enhanced reliability compared to the original P-rated part.

Upgraded Specifications: RNC55H1003BSRE6 and RNC55J1003BSRE6 offer tighter tolerance specifications at ±0.1%, suitable for applications requiring improved accuracy. RNC55J1003BSRE6 additionally provides a superior temperature coefficient of ±25ppm/°C compared to the standard ±50ppm/°C. Both upgrade options are available in cut tape packaging and carry S-class failure ratings.

All substitute parts maintain active product status and are manufactured by Vishay Dale under the MIL-PRF-55182/01 military specification.

Frequently Asked Questions (FAQ)

Q: Can RNC55H1003FSRE6 replace RNC55H1003FPRSL in my design? A: Yes. RNC55H1003FSRE6 is electrically and mechanically equivalent. The primary difference is packaging format: cut tape instead of tape & reel. Both maintain 100 kOhms ±1% resistance, 0.125W power rating, and identical physical dimensions.

Q: What is the difference between the ±1% and ±0.1% tolerance options? A: RNC55H1003BSRE6 and RNC55J1003BSRE6 provide ±0.1% tolerance compared to ±1% in the original part. This tighter tolerance is suitable for precision applications where resistance accuracy is critical. All other electrical and mechanical parameters remain identical.

Q: How does temperature coefficient affect part selection? A: Temperature coefficient indicates resistance change over temperature range. The original part and most substitutes operate at ±50ppm/°C. RNC55J1003BSRE6 offers ±25ppm/°C, providing superior stability across the -65°C to 175°C operating range. Selection depends on application temperature sensitivity requirements.

Q: What do the failure rate classifications mean? A: Failure rate classifications (P, R, S) indicate reliability levels under MIL-PRF-55182/01 specification. P = 0.1%, R = 0.01%, S = 0.001% per 1000 hours. Higher classifications (R and S) represent lower failure rates and improved reliability. All substitutes maintain military-grade reliability standards.

Q: Does packaging format affect electrical performance? A: No. Tape & Reel, Bulk, and Cut Tape formats are packaging and delivery methods only. Electrical and mechanical specifications remain identical across all packaging options. Selection is based on assembly process requirements and inventory management.

Q: Are all substitute parts RoHS compliant? A: No. All listed parts, including the original RNC55H1003FPRSL, are RoHS non-compliant. This is consistent with military-grade specifications under MIL-PRF-55182/01.
