Key Parameters

Substitute Part Grouping Explanation

Substitution of rectangular connector headers is determined by strict equivalence across the following critical parameters:

Mechanical Compatibility:

• Number of positions (40)
• Pitch spacing (0.100" / 2.54mm)
• Mounting type (Through Hole)
• Contact type (Male Pin)
• Overall connector dimensions and insulation height

Electrical Compatibility:

• Current rating (3A)
• Operating temperature range (-55°C to 125°C)
• Contact material and finish specifications
• Voltage rating capability

Functional Compatibility:

• Connector series (AMPMODU Mod II)
• Termination method (Press-Fit, Solder)
• Fastening type (Push-Pull)
• Board-to-board or cable application support

The substitute part 8-103336-3 maintains full equivalence across all mechanical, electrical, and functional parameters. The primary distinction is product status and regulatory compliance, not performance characteristics.

Engineering Selection Recommendations

For Active Production and New Designs: The substitute part 8-103336-3 is the appropriate selection. This part maintains Active product status, ensuring long-term availability and supply chain continuity. The part is RoHS Compliant, meeting current regulatory requirements for electronic components in most jurisdictions.

For Existing Designs Using 3-103336-3: Direct substitution with 8-103336-3 is supported. All mechanical, electrical, and functional parameters are equivalent. The contact finish on the post differs only in composition (Tin versus Tin-Lead), which does not affect electrical performance or mechanical compatibility. Both finishes provide equivalent solderability and contact reliability.

Regulatory Compliance Consideration: The transition from RoHS non-compliant (3-103336-3) to RoHS Compliant (8-103336-3) represents an improvement in regulatory alignment. Applications subject to RoHS directives or customer requirements for RoHS compliance should utilize 8-103336-3.

Supply Chain Status: The 3-103336-3 designation as Last Time Buy indicates production discontinuation. Existing inventory of 890 pieces is available, but future procurement must transition to 8-103336-3, which has 892 pieces in current stock and Active product status.

Frequently Asked Questions (FAQ)

Q: Can 8-103336-3 be used as a direct replacement for 3-103336-3 in existing applications?

A: Yes. The parts are mechanically and electrically equivalent across all critical parameters including position count, pitch spacing, current rating, operating temperature range, and contact specifications. No design modifications are required.

Q: What is the difference between the Tin-Lead finish on 3-103336-3 and the Tin finish on 8-103336-3?

A: Both finishes provide equivalent solderability and contact reliability. The Tin finish on 8-103336-3 reflects RoHS compliance requirements, which restrict lead content in electronic components. This change does not affect electrical performance or mechanical compatibility.

Q: Why is 3-103336-3 marked as Last Time Buy?

A: Last Time Buy status indicates that TE Connectivity has discontinued production of this part number. Existing inventory is available for purchase, but no future production is planned. The substitute part 8-103336-3 is the active replacement.

Q: Are there any PCB layout or footprint changes between these parts?

A: No. Both parts share identical mechanical dimensions, pitch spacing, contact positions, and mounting specifications. PCB footprints and assembly processes remain unchanged.

Q: What is the inventory status for each part?

A: 3-103336-3 has 890 pieces available as New Original In Stock. 8-103336-3 has 892 pieces available as New Original In Stock with Active product status.

Q: Does the RoHS compliance difference affect component selection?

A: For applications subject to RoHS directives or customer specifications requiring RoHS compliance, 8-103336-3 is the required selection. For applications without RoHS requirements, both parts are functionally equivalent.

Q: Are both parts from the same AMPMODU Mod II series?

A: Yes. Both 3-103336-3 and 8-103336-3 are members of the TE Connectivity AMPMODU Mod II connector series, ensuring design consistency and compatibility with existing connector ecosystems.
