The identified substitute part RLR07C1272FSB14 maintains complete parametric equivalence across all electrical and mechanical specifications, differing only in manufacturing batch designation and inventory availability.

Parameter Comparison

Engineering Selection Recommendations

Both RLR07C1272FSBSL and RLR07C1272FSB14 are active products manufactured by Vishay Dale with identical electrical and mechanical specifications. Selection between these parts should be based on inventory availability and supply chain requirements. The RLR07C1272FSB14 offers higher current stock levels (1082 units versus 708 units), which may provide advantages for procurement lead time and production scheduling. Both parts maintain RoHS non-compliant status and REACH Affected classification, with identical ECCN (EAR99) and HTSUS (8533.21.0090) designations. No technical differentiation exists between these components for circuit design or performance applications.

Frequently Asked Questions (FAQ)

Q: Can RLR07C1272FSB14 be used as a direct replacement for RLR07C1272FSBSL?

A: Yes. Both parts are parametrically equivalent across all electrical specifications (12.7 kOhms ±1%, 0.25W metal film), mechanical dimensions (0.090" Dia × 0.250" L axial), and military performance characteristics (MIL-PRF-39017/01, -65°C to 150°C operating range, S-class failure rate).

Q: What determines substitution eligibility for RLR07 series resistors?

A: Substitution requires matching resistance value, tolerance, power rating, composition type, temperature coefficient, operating temperature range, package configuration, physical dimensions, and military series compliance. All these parameters must be identical between the main part and substitute.

Q: Are there any compliance differences between these parts?

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

Q: What is the significance of the batch designation difference (FSBSL versus FSB14)?

A: The batch designation indicates different manufacturing runs or packaging batches from Vishay Dale. This does not affect electrical performance, mechanical compatibility, or circuit functionality. The difference is administrative and supply-chain related.

Q: Can these axial resistors be used in applications requiring surface-mount components?

A: No. Both parts are through-hole axial components designed for insertion into PCB holes. Surface-mount applications require different package types (0603, 0805, 1206, etc.).
