Engineering Selection Recommendations

The KBP01M-E4/51 is obsolete and only available from stock. Substitute part numbers KBP01G and KBP201G are active status devices. All listed substitute parts are ROHS3 compliant and have an MSL of 1 (Unlimited), and share the ECCN and HTSUS classifications. KBP01G maintains a REACH unaffected status, matching the original, while KBP201G is REACH affected. Only parameters and compliance information provided in input are considered.

Frequently Asked Questions (FAQ)

Q1: What parameters define direct substitution for KBP01M-E4/51 bridge rectifiers?
Substitution is defined by matching: diode type (single-phase), technology (standard), maximum peak reverse voltage (100 V), average rectified current (≥1.5 A), maximum forward voltage, maximum reverse leakage current, operating temperature range, mounting type (through hole), package format, and compliance characteristics.

Q2: How important is the package in selecting a replacement bridge rectifier?
Package compatibility is managed by specifying the required mounting type (through hole) and comparable package formats (KBPM, KBP, 4-SIP, 4-ESIP) according to the input data.

Q3: Are all recommended substitutes RoHS compliant?
All substitute part numbers, KBP01G and KBP201G, are flagged as ROHS3 compliant.

Q4: What differences in compliance status should be considered?
REACH status differs between substitutes: KBP01G is REACH unaffected, KBP201G is REACH affected. MSL and RoHS are consistent across all models.

Q5: How should ECCN and HTSUS codes be used in selection?
All parts referenced share ECCN EAR99 and HTSUS 8541.10.0080, maintaining categorical consistency during substitution.

Q6: What are the inventory statuses for alternatives?
KBP01G and KBP201G substitute parts are listed as "Active" with available inventory. The original KBP01M-E4/51 is "Obsolete" with noted existing stock.
