Key Parameters

Substitute Part Grouping Explanation

Substitution of the DM1AA-SF-PEJ(22) is determined by strict equivalence across the following parameters:

• Card Type: Secure Digital - SD
• Number of Positions: 12 (9 + 3)
• Mounting Type: Surface Mount, Right Angle
• Insertion/Removal Method: Push In, Push Out
• Height Above Board: 0.114" (2.90mm)
• Contact Finish: Gold
• Contact Finish Thickness: 8.00µin (0.203µm)
• Features: Board Guide, Switch
• Base Product Number: DM1AA
• Manufacturer: Hirose Electric Co Ltd

The DM1AA-SF-PEJ(82) meets all these criteria and is classified as an active product, making it a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The DM1AA-SF-PEJ(82) is the direct equivalent for the obsolete DM1AA-SF-PEJ(22). Both parts share identical electrical and mechanical specifications across all critical parameters. The DM1AA-SF-PEJ(82) carries active product status and ROHS3 compliance, providing improved regulatory alignment compared to the RoHS Compliant designation of the original part. Inventory availability of 5,897 pieces supports production continuity. No design modifications are required for substitution.

Frequently Asked Questions (FAQ)

Q: Can DM1AA-SF-PEJ(82) be used as a direct replacement for DM1AA-SF-PEJ(22)?

A: Yes. Both parts are identical in card type, position count, mounting configuration, contact specifications, and mechanical dimensions. The DM1AA-SF-PEJ(82) is the active equivalent.

Q: What is the difference between the two part numbers?

A: The suffix designation (22 vs. 82) reflects packaging and product lifecycle status. The DM1AA-SF-PEJ(22) is obsolete; the DM1AA-SF-PEJ(82) is active production. Electrical and mechanical performance are equivalent.

Q: Are there packaging differences?

A: The DM1AA-SF-PEJ(82) is supplied in Cut Tape (CT) and Digi-Reel® packaging. The original part packaging is not specified in available data.

Q: Does the ROHS3 compliance of DM1AA-SF-PEJ(82) affect compatibility?

A: No. ROHS3 compliance is a regulatory enhancement and does not alter electrical or mechanical function. The substitute part meets or exceeds the compliance requirements of the original.

Q: What are the critical parameters for SD card connector substitution?

A: Position count (12 with 9 + 3 configuration), mounting type (surface mount, right angle), insertion method (push in/push out), height above board (2.90mm), and contact finish (gold, 8.00µin thickness) must remain constant for functional equivalence.
