Parameter Comparison

Engineering Selection Recommendations

Both RLR05C1001FSM23 and RLR05C1001FSB14 maintain active product status and carry identical electrical specifications, military-grade certifications, and compliance attributes. Selection between these parts should be based on inventory availability and procurement lead times. Both components are RoHS non-compliant and REACH-affected, with identical ECCN (EAR99) and HTSUS (8533.21.0090) classifications. The RLR05C1001FSB14 currently maintains higher inventory levels (996 units versus 934 units), which may provide supply chain advantages for high-volume applications.

Frequently Asked Questions (FAQ)

Q: Can RLR05C1001FSB14 be used as a direct replacement for RLR05C1001FSM23?

A: Yes. Both parts are parametrically equivalent across all electrical and mechanical specifications, including resistance value, tolerance, power rating, temperature coefficient, operating temperature range, package configuration, and physical dimensions. Direct substitution is supported without circuit redesign.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts carry identical RoHS status (non-compliant), REACH status (affected), ECCN classification (EAR99), and HTSUS codes (8533.21.0090). Military-grade MIL-PRF-39017/05 compliance and failure rate specifications are identical.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by equivalence in resistance (1 kOhms), tolerance (±1%), power rating (0.125W), composition (metal film), temperature coefficient (±100ppm/°C), operating temperature range (-65°C to 150°C), axial package configuration, and physical dimensions (0.066" Dia × 0.150" L). All parameters must match for direct interchangeability.

Q: Are there any packaging or lead configuration differences?

A: No. Both parts use identical axial through-hole packaging with two terminations and matching physical dimensions of 0.066" Dia × 0.150" L (1.68mm × 3.81mm).

Q: Which part should be selected for new designs?

A: Selection should be based on current inventory availability and supply chain requirements. Both parts are active and fully qualified for military and high-reliability applications. The RLR05C1001FSB14 offers higher current stock levels.
