Substitute Part Grouping Explanation

Substitution within the RNC55H2802 family is determined by electrical and mechanical parameter equivalence. The primary substitution criterion is maintenance of identical electrical specifications: 28 kOhms resistance value, ±1% tolerance, 0.125W power rating, metal film composition, ±50ppm/°C temperature coefficient, and -65°C to 175°C operating temperature range. The axial package configuration and physical dimensions (0.094" Dia × 0.250" L) must remain constant. The RNC55H2802FSB14 qualifies as a direct substitute based on these parameters. Differentiation between these parts occurs at the failure rate level: the main part (RNC55H2802FPB14) carries a P-grade failure rate (0.1%), while the substitute (RNC55H2802FSB14) carries an S-grade failure rate (0.001%), indicating enhanced reliability performance under MIL-PRF-55182/01 classification.

Parameter Comparison

Engineering Selection Recommendations

Both RNC55H2802FPB14 and RNC55H2802FSB14 are active products manufactured by Vishay Dale under MIL-PRF-55182/01 military specification. Selection between these parts depends on failure rate requirements. The RNC55H2802FPB14 with P-grade failure rate (0.1%) is suitable for standard military and high-reliability applications. The RNC55H2802FSB14 with S-grade failure rate (0.001%) provides enhanced reliability performance and is appropriate for mission-critical systems requiring lower failure rates. Both parts are RoHS non-compliant and carry EAR99 ECCN classification. The RNC55H2802FSB14 is additionally noted as REACH Affected. Inventory availability is adequate for both variants, with 1138 units of the FSB14 variant and 993 units of the FPB14 variant in stock.

Frequently Asked Questions (FAQ)

Q: Can RNC55H2802FSB14 be used as a direct replacement for RNC55H2802FPB14?

A: Yes. Both parts maintain identical electrical specifications (28 kOhms ±1%, 0.125W, ±50ppm/°C, -65°C to 175°C) and physical dimensions (0.094" Dia × 0.250" L axial package). The primary difference is the failure rate classification: FSB14 carries S-grade (0.001%) versus FPB14's P-grade (0.1%).

Q: What determines substitutability between RNC55H2802 variants?

A: Substitutability is determined by matching resistance value, tolerance, power rating, composition (metal film), temperature coefficient, operating temperature range, package type (axial), and physical dimensions. Failure rate and REACH compliance status do not affect electrical or mechanical compatibility.

Q: Are there any compliance differences between these parts?

A: Both parts are RoHS non-compliant and classified as EAR99. The RNC55H2802FSB14 is additionally designated as REACH Affected, while the RNC55H2802FPB14 does not carry this designation.

Q: Which part should be selected for high-reliability applications?

A: The RNC55H2802FSB14 with S-grade failure rate (0.001%) is specified for applications requiring enhanced reliability performance compared to the P-grade (0.1%) RNC55H2802FPB14.

Q: Are the physical dimensions identical between substitute parts?

A: Yes. Both RNC55H2802FPB14 and RNC55H2802FSB14 share identical axial package dimensions of 0.094" Dia × 0.250" L (2.39mm × 6.35mm), ensuring mechanical compatibility in PCB layouts and through-hole applications.
