Key Parameters

Substitute Part Grouping Explanation

Substitution grouping is based strictly on matching key parameters: input voltage range, output voltage, output current, output power, number of outputs, isolation voltage, operating temperature range, efficiency, mounting type, package dimensions, and compliance statuses (RoHS, REACH, MSL). Substitute parts provided meet or exceed the required electrical and mechanical specifications without deviation from the listed input criteria.

Parameter Comparison

Engineering Selection Recommendations

Engineering selection should consider only active product status, RoHS and REACH compliance, and listed certifications. Both VIBLSD1-S24-S5-SIP and PQME1-S24-S5-S are RoHS compliant, REACH unaffected, and listed as active. Moisture Sensitivity Level is identical at MSL 1 (Unlimited), supporting unrestricted inventory management and assembly.

Frequently Asked Questions (FAQ)

Q1: What are the critical parameters for substituting VIBLSD1-S24-S5-SIP with PQME1-S24-S5-S?
A1: Key substitution parameters include matching input voltage range (22.8V to 25.2V), output voltage (5V), output current (200mA), output power (1W), isolation voltage, number of outputs (1), operating temperature range (-40°C ~ 85°C), mounting type (Through Hole), package dimensions, and compliance statuses.

Q2: Are the package dimensions and mechanical mounting features compatible?
A2: Both DC-DC converter modules share similar dimensions (approximately 0.77" x 0.24" x 0.40") and are designed for through-hole mounting, with 4-lead SIP form factors. Differences in the SIP module specification count should be verified against PCB layout requirements.

Q3: What compliance and certification statuses are provided for these parts?
A3: Both models are RoHS compliant and REACH unaffected, with an MSL rating of 1 (Unlimited).

Q4: Is there any difference in the isolation voltage between the main and substitute part?
A4: VIBLSD1-S24-S5-SIP provides 1 kV isolation, whereas PQME1-S24-S5-S offers 1.5 kV isolation.

Q5: Are there differences in efficiency or performance parameters?
A5: PQME1-S24-S5-S features slightly higher efficiency (73%) compared to VIBLSD1-S24-S5-SIP (70%).

Q6: How should PCB designers handle slight differences in SIP package specification?
A6: For mechanical compatibility, review mechanical drawings to confirm SIP lead spacing and count match application requirements. Package dimensions are nearly identical, but the SIP specification and mechanical fit must be confirmed against the design.
