Substitute Part Grouping Explanation

Substitute parts for the RNC55H3242FSBSL are identified based on strict equivalence across all critical electrical and mechanical parameters. The substitution logic is based on the following criteria:

• Resistance Value: Exact match at 32.4 kOhms
• Tolerance: Exact match at ±1%
• Power Rating: Exact match at 0.125W (1/8W)
• Composition: Metal Film construction
• Temperature Coefficient: ±50ppm/°C
• Operating Temperature Range: -65°C to 175°C
• Package Type: Axial configuration
• Physical Dimensions: 0.094" Dia × 0.250" L (2.39mm × 6.35mm)
• Series Compliance: MIL-PRF-55182/01 military specification
• Failure Rate: S (0.001%)

The RNC55H3242FSB14 meets all these criteria and is classified as a parametric equivalent. Both parts share identical base product number (RNC55) and are manufactured by the same supplier (Vishay Dale), ensuring functional and mechanical interchangeability.

Parameter Comparison

Engineering Selection Recommendations

Both the RNC55H3242FSBSL and RNC55H3242FSB14 are active production parts manufactured by Vishay Dale under the military RNC55 series. Selection between these parts should be based on the following factors:

• Military Compliance: Both parts comply with MIL-PRF-55182/01 specifications and are suitable for military and aerospace applications.
• RoHS Status: Both parts are RoHS non-compliant, consistent with military-grade component standards.
• REACH Compliance: The RNC55H3242FSB14 is marked as REACH Affected; verify REACH compliance requirements for your specific application.
• Electrical Performance: Identical electrical characteristics ensure direct substitution without circuit redesign or re-qualification.

Frequently Asked Questions (FAQ)

Q: Can the RNC55H3242FSB14 be used as a direct replacement for the RNC55H3242FSBSL?

A: Yes. Both parts are parametric equivalents with identical resistance value (32.4 kOhms), tolerance (±1%), power rating (0.125W), temperature coefficient (±50ppm/°C), operating temperature range (-65°C to 175°C), and axial package dimensions (0.094" Dia × 0.250" L). They are manufactured by the same supplier under the same military specification (MIL-PRF-55182/01).

Q: Are there any physical differences between these parts?

A: No. Both parts have identical physical dimensions (0.094" Dia × 0.250" L / 2.39mm × 6.35mm), package type (axial), and number of terminations (2). They are mechanically interchangeable in all applications.

Q: What is the difference between the part numbers RNC55H3242FSBSL and RNC55H3242FSB14?

A: The part numbers differ only in their suffix designations (SL vs. 14). Both parts share the same base product number (RNC55) and identical electrical and mechanical specifications. The suffix variation reflects different manufacturing batches or packaging configurations from Vishay Dale.

Q: Are both parts suitable for military and aerospace applications?

A: Yes. Both parts comply with MIL-PRF-55182/01 military specifications and feature moisture-resistant, weldable metal film construction. They are rated for military-grade reliability with a failure rate of S (0.001%).

Q: What should I verify before substituting these parts in my design?

A: Verify REACH compliance requirements for your specific application, as the RNC55H3242FSB14 is marked as REACH Affected. Both parts are RoHS non-compliant; confirm this aligns with your product compliance requirements. Electrical performance is identical, so no circuit re-qualification is necessary.
