Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the 101-00581-59 is determined by the following critical parameters:

Primary Substitution Criteria:

• Card Type: Secure Digital - microSD™ (mandatory match)
• Number of Positions: 10 (8 + 2) configuration (primary compatibility requirement)
• Connector Type: Connector and Ejector with Push In/Push Out mechanism
• Mounting Type: Surface Mount, Right Angle orientation
• Contact Finish: Gold plating

Secondary Compatibility Factors:

• Height Above Board: tolerance range 0.066" to 0.073" (1.68mm to 1.85mm)
• Contact Finish Thickness: 15.0µin to 30.0µin (0.38µm to 0.76µm)
• RoHS and MSL compliance status

Substitute parts are grouped into two categories:

Group A - Direct Equivalents (10-position, 8+2 configuration):

• 5025700893 (Molex 502570 series)
• 5027740891 (Molex 502774 series)
• DM3AT-SF-PEJM5(41) (Hirose DM3 series)

Group B - Functional Alternatives (9-position, 8+1 configuration):

• GTFP08431BEU (Amphenol ICC GTFP series)
• MEM2051-00-195-00-A (GCT MEM2051 series)

Group C - Reduced Position Alternative (8-position configuration):

• 2908-05WB-MG (3M 2900 series)

Parameter Comparison

Engineering Selection Recommendations

For Direct Pin-Compatible Replacement (10-position, 8+2 configuration):

The Molex 5025700893 (502570 series) and Molex 5027740891 (502774 series) are the primary active alternatives. Both maintain the 10-position configuration with identical contact finish thickness (20.0µin) matching the original part. The 5025700893 features standard top-side mounting, while the 5027740891 provides reverse bottom-side mounting for alternative PCB layout requirements. Both are ROHS3 compliant with active product status and high inventory availability.

The Hirose DM3AT-SF-PEJM5(41) provides a 10-position equivalent with the lowest height above board (0.066"), suitable for space-constrained applications. This part maintains RoHS compliance and active status.

For Reduced Position Configurations:

The Amphenol ICC GTFP08431BEU and GCT MEM2051-00-195-00-A both provide 9-position (8+1) alternatives. The GTFP08431BEU is active with higher contact finish thickness (30.0µin), while the MEM2051-00-195-00-A is obsolete. Selection between these depends on whether the additional contact position is functionally required.

The 3M 2908-05WB-MG provides an 8-position alternative for applications where reduced contact count is acceptable. This part is active with ROHS3 compliance.

Compliance Considerations:

All substitute parts maintain MSL 1 rating and RoHS compliance. Parts with ROHS3 status (Molex, 3M, GCT, Amphenol ICC GTFP series) represent current regulatory compliance. The Hirose DM3AT-SF-PEJM5(41) maintains RoHS Compliant status. Selection should prioritize active product status for long-term supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can the 101-00581-59 be directly replaced with a 9-position connector?

A: The GTFP08431BEU and MEM2051-00-195-00-A provide 9-position (8+1) alternatives. Direct replacement is possible only if the application does not require the additional contact position provided by the 10-position configuration. Verify PCB layout and firmware compatibility before substitution.

Q: What is the difference between the Molex 5025700893 and 5027740891?

A: Both are 10-position Molex microSD connectors with identical electrical specifications and contact finish thickness. The primary difference is mounting feature: the 5025700893 uses standard top-side mounting, while the 5027740891 uses reverse bottom-side mounting. Selection depends on PCB layout orientation requirements.

Q: Is the Hirose DM3AT-SF-PEJM5(41) suitable for height-constrained applications?

A: Yes. The DM3AT-SF-PEJM5(41) has the lowest height above board (0.066" / 1.68mm) among the 10-position alternatives, making it suitable for applications with vertical space constraints. Verify PCB clearance requirements before selection.

Q: Why is the 3M 2908-05WB-MG listed as an alternative if it has only 8 positions?

A: The 2908-05WB-MG is included as a functional alternative for applications where the full 10-position contact count is not required. It maintains push-push ejection, surface mount right-angle mounting, and gold contact finish. Use only if the application firmware and PCB design support 8-position operation.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts are either RoHS Compliant or ROHS3 Compliant. ROHS3 status indicates compliance with current regulatory requirements. The original 101-00581-59 and Hirose DM3AT-SF-PEJM5(41) are RoHS Compliant; all other substitutes are ROHS3 Compliant.

Q: What is the significance of contact finish thickness variation?

A: Contact finish thickness ranges from 15.0µin (3M 2908-05WB-MG) to 30.0µin (Amphenol ICC GTFP08431BEU). The original part specifies 20.0µin. Thicker finishes provide enhanced durability for high-cycle insertion applications; thinner finishes reduce material cost. Selection should align with application insertion cycle requirements and reliability specifications.

Q: Can the MEM2051-00-195-00-A be used despite its obsolete status?

A: The MEM2051-00-195-00-A is listed as obsolete. While current inventory is available (1026 pcs), future supply cannot be guaranteed. Use only if no active alternatives meet application requirements, and establish long-term supply chain contingency planning.

Q: What packaging options are available for these substitutes?

A: Molex parts (5025700893, 5027740891) and 3M 2908-05WB-MG are available in Cut Tape (CT) and Digi-Reel® packaging. Amphenol ICC GTFP08431BEU and Hirose DM3AT-SF-PEJM5(41) are available in Cut Tape (CT). GCT MEM2051-00-195-00-A is available in Cut Tape (CT) and Digi-Reel®. Verify packaging requirements for automated assembly processes.
