CCM03-3504 SIM/SAM Card Connector Equivalent & Substitute Parts

Part Overview

The CCM03-3504 is an 8-position SIM/SAM card connector manufactured by C&K, designed for surface mount, right-angle applications with push-in/pull-out insertion and removal. This connector features gold-plated contacts and is part of the CCM03 MK II series.

The CCM03-3504 is currently classified as obsolete. Identifying equivalent and substitute parts is necessary to ensure continued availability for new designs, production continuity, and long-term component sourcing strategies.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CCM03-3504 is determined by the following critical parameters:

• Card Type: Must support SIM and SAM card standards
• Number of Positions: Must be 8-position configuration
• Mounting Type: Must be surface mount with right-angle orientation
• Insertion/Removal Method: Must support push-in/pull-out mechanism
• Height Above Board: Must be 0.118" (3.00mm)
• Contact Finish: Must be gold-plated
• Moisture Sensitivity Level: Must be MSL 1 or equivalent
• Series Compatibility: Must be from CCM03 MK II series

The substitute part CCM03-3504LFT R122 meets all these critical parameters and is therefore a direct functional equivalent.

Engineering Selection Recommendations

The CCM03-3504LFT R122 is the direct substitute for the obsolete CCM03-3504. Key considerations for selection:

Product Status: The CCM03-3504LFT R122 is active and currently in production, ensuring long-term availability and supply chain stability compared to the obsolete CCM03-3504.

Compliance: The CCM03-3504LFT R122 is ROHS3 compliant, whereas the original CCM03-3504 is RoHS non-compliant. This compliance upgrade is significant for applications subject to RoHS regulations.

Packaging: The substitute is supplied in Tape & Reel (TR) format, which is standard for automated assembly processes and differs from bulk packaging of the original part.

Electrical and Mechanical Compatibility: All functional parameters—card type, position count, mounting configuration, insertion method, height, and contact finish—are identical between the two parts, ensuring direct functional interchangeability.

Frequently Asked Questions (FAQ)

Q: Can CCM03-3504LFT R122 be used as a direct replacement for CCM03-3504?

A: Yes. The CCM03-3504LFT R122 is electrically and mechanically identical to the CCM03-3504 across all critical parameters: 8-position SIM/SAM card configuration, surface mount right-angle mounting, push-in/pull-out mechanism, 3.00mm height, and gold contact finish.

Q: What is the primary difference between these two parts?

A: The main differences are product status and compliance. The CCM03-3504LFT R122 is active and ROHS3 compliant, while the CCM03-3504 is obsolete and RoHS non-compliant. Packaging also differs: the substitute uses Tape & Reel format versus bulk.

Q: Does the Tape & Reel packaging affect compatibility?

A: No. Tape & Reel packaging is a supply format used for automated assembly and does not affect the connector's electrical or mechanical performance. The connector itself is identical.

Q: Are there any design changes between the CCM03-3504 and CCM03-3504LFT R122?

A: No design changes exist. Both connectors are from the same CCM03 MK II series and share identical specifications for card type, position count, mounting type, insertion method, height, and contact finish.

Q: Is the ROHS3 compliance upgrade important?

A: ROHS3 compliance is required for products sold in regions with RoHS regulations. If your application or market requires RoHS compliance, the CCM03-3504LFT R122 is the appropriate choice.
