Key Parameters

Substitute Part Grouping Explanation

Substitution of the DM1AA-SF-PEJ is determined by strict equivalence across the following critical parameters:

• Card Type: Secure Digital - SD
• Number of Positions: 12 (9 + 3)
• Connector Type: Connector and Ejector
• Insertion/Removal Method: Push In, Push Out
• Mounting Type: Surface Mount, Right Angle
• Height Above Board: 0.114" (2.90mm)
• Contact Finish: Gold
• Contact Finish Thickness: 8.00µin (0.203µm)

The DM1AA-SF-PEJ(72) meets all these criteria and is classified as the manufacturer-recommended equivalent. Both parts share the same base product number (DM1AA) and series designation, confirming functional and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The DM1AA-SF-PEJ(72) is the direct equivalent for the obsolete DM1AA-SF-PEJ. Both components are manufactured by Hirose Electric Co Ltd and share identical electrical and mechanical specifications across all critical parameters. The substitute part is currently in active production status with confirmed inventory availability (1262 pcs), whereas the original part is obsolete.

The DM1AA-SF-PEJ(72) provides enhanced compliance with ROHS3 certification compared to the original RoHS Compliant designation. The substitute is supplied in Tray packaging and includes an integrated Switch feature in addition to the Board Guide feature of the original part. These additions do not affect functional compatibility and represent design improvements in the active production variant.

Frequently Asked Questions (FAQ)

Q: Can the DM1AA-SF-PEJ(72) be used as a direct replacement for the DM1AA-SF-PEJ?

A: Yes. Both parts are identical in card type, position count, connector type, ejection method, mounting configuration, and contact specifications. The substitute is the manufacturer-recommended equivalent and is currently in active production.

Q: What is the difference between the original and substitute part?

A: The DM1AA-SF-PEJ(72) includes an integrated Switch feature and is supplied in Tray packaging. It also carries ROHS3 certification versus RoHS Compliant on the original. These are enhancements that do not affect electrical or mechanical compatibility.

Q: Why is the original DM1AA-SF-PEJ listed as obsolete?

A: The DM1AA-SF-PEJ has been superseded by the DM1AA-SF-PEJ(72) in the manufacturer's active product line. The substitute part provides the same functionality with improved compliance and packaging options.

Q: Are there any PCB layout or footprint changes required when switching to the DM1AA-SF-PEJ(72)?

A: No. Both parts share identical mounting type (Surface Mount, Right Angle), height above board (0.114" / 2.90mm), and contact specifications. PCB footprints and assembly procedures remain unchanged.

Q: What is the Moisture Sensitivity Level (MSL) for both parts?

A: Both the DM1AA-SF-PEJ and DM1AA-SF-PEJ(72) have an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
