Key Parameters

Substitute Part Grouping Explanation

Substitute selection for the BA4558RFV-E2 is based strictly on matching the following parameters as provided: amplifier type (general purpose), number of circuits (2), slew rate, gain bandwidth product, input bias current, input offset voltage, output/channel current, supply voltage range, operating temperature range, mounting type (surface mount), package/case (8-pin, 0.173", 4.40mm width), RoHS and REACH compliance, and product status. Only parts listed that match these key parameters are included as substitutes.

Parameter Comparison

Engineering Selection Recommendations

Selection between BA4558RFV-E2, RC4558PW, and RC4558PWR can be based on product status, RoHS3 and REACH compliance, and moisture sensitivity level (MSL). BA4558RFV-E2 and RC4558PWR are both active and ROHS3 compliant with unlimited MSL and unaffected REACH status. RC4558PW is listed as Last Time Buy and meets the same compliance requirements.

Frequently Asked Questions (FAQ)

Q1: What parameters are critical when substituting BA4558RFV-E2 with RC4558PW or RC4558PWR?
A1: Critical parameters include amplifier type, number of circuits, gain bandwidth product, slew rate, input offset voltage, input bias current, supply voltage range, current output/channel, operating temperature, package width, mounting type, RoHS and REACH compliance, MSL, and product status.

Q2: Are package differences significant when considering substitution?
A2: The BA4558RFV-E2 uses 8-LSSOP (0.173", 4.40mm width), while the substitutes use 8-TSSOP (0.173", 4.40mm width). As both packages share the same pin count and width, mechanical compatibility must be confirmed strictly based on the given dimensions.

Q3: How do compliance and product status impact selection?
A3: All listed substitute parts are ROHS3 compliant, have MSL 1 (unlimited), and REACH unaffected. Product status impacts long-term availability: BA4558RFV-E2 and RC4558PWR are active, while RC4558PW is last time buy.

Q4: Can these substitutes be used in the same application environments as the main part?
A4: Substitute parts must meet or exceed the operating temperature range, supply voltage range, and electrical specifications provided in the comparison table. Compatibility is determined by the listed parameters only.

Q5: What is the effect of supply voltage range and temperature ratings when choosing a substitute?
A5: Ensure that the substitute's voltage and temperature ratings meet the requirements of your application as detailed in the table above. Only the ranges listed in the input are used to determine equivalence.
