Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 1903572-1 are identified based on electrical and mechanical compatibility within the SD card connector category. The primary substitution criteria are:

Critical Matching Parameters:

• Card Type: Secure Digital - SD
• Number of Positions: 11 (9 + 2)
• Connector Type: Connector and Ejector
• Insertion/Removal Method: Push In, Push Out
• Contact Finish: Gold
• Moisture Sensitivity Level: 1 (Unlimited)
• RoHS Compliance Status

Allowable Variations:

• Mounting Type: Through Hole versus Surface Mount (design-dependent)
• Height Above Board: Minor variations within tolerance (0.177" to 0.179")
• Features: Board Lock/Switch configurations
• Product Status: Active substitutes preferred for obsolete parts

The substitute part Amphenol ICC 1010040575# maintains electrical compatibility through identical SD card specifications, position count, and contact materials. The primary difference is the mounting technology (Surface Mount versus Through Hole), which requires design consideration during component selection.

Parameter Comparison

Engineering Selection Recommendations

For Direct Through-Hole Replacement: The TE Connectivity 1903572-1 is obsolete. Direct replacement with an equivalent through-hole SD card connector requires sourcing from remaining inventory or identifying alternative through-hole options not listed in the provided substitute data.

For Surface Mount Design Adaptation: The Amphenol ICC 1010040575# provides electrical and functional equivalence to the 1903572-1 with the following considerations:

• Both connectors maintain identical SD card specifications and position counts
• Both feature gold-plated contacts and push-in/push-out ejection mechanisms
• Both comply with RoHS standards and feature MSL 1 rating
• Height above board variation (0.177" versus 0.179") is within typical manufacturing tolerance
• Mounting technology differs (Surface Mount versus Through Hole), requiring PCB redesign

The Amphenol ICC part is currently active in production, ensuring long-term availability and supply chain stability compared to the obsolete TE Connectivity part.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol ICC 1010040575# directly replace the TE Connectivity 1903572-1 on existing PCBs?

A: Direct PCB replacement is not possible due to mounting type differences. The 1903572-1 uses through-hole mounting, while the 1010040575# uses surface mount technology. PCB redesign is required for substitution.

Q: Are the electrical specifications identical between these two connectors?

A: Yes. Both connectors support the same Secure Digital (SD) card standard with 11 positions (9 + 2), identical contact materials (gold), and equivalent ejection mechanisms (push-in, push-out).

Q: What is the significance of the height above board difference (0.177" versus 0.179")?

A: The 0.002" (0.05mm) difference falls within standard manufacturing tolerances for SD card connectors and does not affect functional compatibility with SD cards or electrical performance.

Q: Do both connectors meet the same compliance standards?

A: Both connectors are RoHS compliant and carry identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications. The 1903572-1 is ROHS3 compliant, while the 1010040575# is RoHS compliant. Both feature MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the difference between "Board Lock" and "Board Guide" features?

A: Both features provide mechanical stability during card insertion and removal. Board Lock and Board Guide represent different mechanical implementations of the same functional objective within their respective mounting technologies.

Q: Why is the 1903572-1 listed as obsolete?

A: Obsolete status indicates the part is no longer in active production. Existing inventory may be available, but long-term supply cannot be guaranteed. Active substitute parts ensure design continuity for new production and future maintenance requirements.
