Key Parameters

Substitute Part Grouping Explanation

Substitute selection for the P0900SARP is governed strictly by the following parameters: Voltage Breakover (98V), Voltage Off State (75V), Voltage On State (4V), Current Peak Pulse (8/20µs: 150A), Current Peak Pulse (10/1000µs: 45A), Current Hold (150mA), Number of Elements (1), Capacitance (55pF), Surface Mount mounting, DO-214AA (SMB) package, and identical supplier device package. RoHS, MSL, ECCN, and HTSUS are considered solely for compliance matching. Only parts fulfilling these exact criteria qualify as substitute models.

Parameter Comparison

Engineering Selection Recommendations

P0900SARP is classified as obsolete. The substitute part P0900SALRP maintains full equivalence in all specified electrical, mechanical, and package characteristics. P0900SALRP offers ROHS3 compliance, enabling selection when environmental regulations require RoHS-compliant materials. Moisture Sensitivity Level, ECCN, and HTSUS are matched across both models, providing regulatory and handling consistency.

Frequently Asked Questions (FAQ)

Q1: What parameters must match for a valid substitute in Transient Voltage Suppressors (TVS) like P0900SARP?
A1: Substitute validation is performed on Voltage Breakover, Voltage Off State, Voltage On State, Peak Pulse Current ratings (8/20µs and 10/1000µs), Current Hold, Capacitance, Number of Elements, Mounting Type, package/case, Moisure Sensitivity Level, and compliance certifications.

Q2: Is P0900SALRP fully compatible as a substitute for P0900SARP?
A2: P0900SALRP matches all required electrical, mechanical, and package specifications as listed. It is a direct substitute within the Transient Voltage Suppressors (TVS) category.

Q3: What is the significance of RoHS compliance between these models?
A3: P0900SALRP is ROHS3 Compliant while P0900SARP is RoHS non-compliant. Selection should consider compliance with required material safety standards.

Q4: Does the package difference affect substitutability?
A4: Both parts are provided in the DO-214AA, SMB surface mount package, ensuring full mechanical and layout compatibility.

Q5: Are inventory and series status relevant to substitution?
A5: Product status is relevant; P0900SALRP is active, while P0900SARP is obsolete. Series and package attributes are maintained for substitute equivalence.
