• Composition: Metal Film
• Package: Axial
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -65°C to 150°C
• Military series compliance: MIL-PRF-39017/01, RLR07 base product

The identified substitute part maintains identical electrical and mechanical specifications, ensuring direct functional equivalence without circuit redesign or performance degradation.

Parameter Comparison

Engineering Selection Recommendations

Both the RLR07C4750FSBSL and RLR07C4750FSB14 are active products from Vishay Dale with identical electrical and mechanical specifications. Selection between these parts should be based on procurement availability and lead time requirements. Both components maintain the same military qualification status under MIL-PRF-39017/01 and carry equivalent compliance certifications (RoHS non-compliant, REACH Affected, ECCN EAR99). The failure rate classification of S (0.001%) is consistent across both parts, supporting equivalent reliability performance in military and high-reliability applications.

Frequently Asked Questions (FAQ)

Q: Can RLR07C4750FSB14 be used as a direct replacement for RLR07C4750FSBSL?

A: Yes. Both parts are electrically and mechanically identical, with matching resistance values (475 Ohms), tolerance (±1%), power rating (0.25W), composition (metal film), package type (axial), and operating specifications. No circuit modifications are required.

Q: Are there differences in military qualification between these parts?

A: No. Both parts comply with MIL-PRF-39017/01 specifications and belong to the RLR07 military series. Failure rate classification and military features are identical.

Q: What determines substitution eligibility for this resistor?

A: Substitution is based on exact equivalence of resistance value, tolerance, power rating, composition, package type, temperature coefficient, operating temperature range, and military series compliance. Deviations in any of these parameters disqualify a part from direct substitution.

Q: Are there compliance or regulatory differences between these parts?

A: No. Both parts share identical RoHS status (non-compliant), REACH status (Affected), ECCN classification (EAR99), and HTSUS codes (8533.21.0090).

Q: Which part should be selected based on availability?

A: Selection should prioritize procurement lead time and inventory availability. The RLR07C4750FSB14 currently has higher inventory (1065 Pcs) compared to the RLR07C4750FSBSL (830 Pcs), which may influence procurement decisions for time-sensitive applications.
