Engineering Selection Recommendations

All identified substitute parts maintain active product status and comply with RoHS regulations. Selection among equivalent parts is determined by specific application requirements and mechanical constraints.

TE Connectivity AMP Connectors 5499206-7: This part is functionally equivalent to the main part number within the same manufacturer series (AMP-Latch). Both parts share identical mating pitch, row spacing, and insulation height. The primary difference is contact post length (0.110" versus 0.155"), which affects overall contact length and board-to-board stacking height. This part is suitable for applications with reduced post length requirements and offers higher inventory availability (2200 units).

Amphenol ICC (FCI) 71918-130LF: This part operates within the Quickie™ series and maintains all critical connector parameters including pitch, row spacing, and shrouding. Differences include increased insulation height (0.685" versus 0.549"), contact material composition (Phosphor Bronze versus unspecified), and contact finish thickness on the post (78.7µin versus 100.0µin). This part is supplied in tube packaging rather than tray. Operating temperature and current rating specifications are not provided for this part.

3M N3440-6302RB: This part operates within the 3000 series and maintains all critical connector parameters. The contact post length is 0.112" (intermediate between the main part and 5499206-7). Operating temperature range is -55°C to 105°C (versus -65°C to 105°C for the main part). Current rating is specified at 1.75A per contact (higher than the main part's 1A). Contact finish thickness on the post is 200.0µin (thicker than the main part's 100.0µin). Voltage rating is not specified.

3M N3440-6303RB: This part operates within the 3000 series and is mechanically identical to the main part in contact post length (0.155"), overall contact length (0.695" versus 0.684"), and mating contact length (0.240"). Operating temperature range is -55°C to 105°C. Current rating is 1.75A per contact. Contact finish thickness on the post is 200.0µin. Voltage rating is not specified. This part offers the closest mechanical alignment to the main part number.

Frequently Asked Questions (FAQ)

Q: Can I substitute 5499206-7 for 2-5102321-7 in my application?

A: Substitution is permissible if your application accommodates the reduced contact post length (0.110" versus 0.155"). This affects overall connector height and board-to-board stacking distance. Both parts share identical mating pitch (0.100"), row spacing (0.100"), number of positions (30), and shrouding configuration. Verify that your PCB layout and mating connector accommodate the shorter post length before implementation.

Q: What is the primary difference between the TE Connectivity and 3M substitute parts?

A: The TE Connectivity 5499206-7 maintains the same series designation (AMP-Latch) as the main part. The 3M N3440-6302RB and N3440-6303RB parts operate within the 3M 3000 series. All parts share identical pitch, row spacing, and position count. The 3M parts specify higher current ratings (1.75A versus 1A) and thicker post contact finish (200.0µin versus 100.0µin). The N3440-6303RB matches the main part's contact post length exactly (0.155").

Q: Does the Amphenol ICC 71918-130LF part have the same electrical specifications as the main part?

A: The 71918-130LF part does not provide specified operating temperature range, current rating, or voltage rating in the available documentation. While the connector maintains the same pitch, row spacing, position count, and shrouding as the main part, electrical performance specifications cannot be confirmed. Consult the manufacturer's datasheet for complete electrical ratings before selecting this part for applications with defined electrical requirements.

Q: Why do the substitute parts have different insulation heights?

A: Insulation height variation reflects different mechanical designs within each manufacturer's connector series. The main part (2-5102321-7) and 5499206-7 both specify 0.549" insulation height. The Amphenol ICC 71918-130LF specifies 0.685", and the 3M parts specify 0.680". These differences affect the overall connector profile and board-to-board spacing. Verify that your PCB layout and mating connector accommodate the specific insulation height of your selected part.

Q: Are all substitute parts RoHS compliant?

A: Yes. The main part is ROHS3 Compliant. All substitute parts are RoHS Compliant. Both designations indicate compliance with RoHS regulations. The ROHS3 designation indicates compliance with the most recent RoHS 3 directive. All parts maintain Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements during storage or assembly.

Q: What is the difference in packaging between these parts?

A: The main part (2-5102321-7), 5499206-7, N3440-6302RB, and N3440-6303RB are supplied in tray packaging. The Amphenol ICC 71918-130LF is supplied in tube packaging. Packaging selection may affect handling, storage, and automated assembly processes. Confirm packaging compatibility with your procurement and assembly procedures.

Q: Can I use N3440-6302RB if my application requires 1A per contact?

A: The N3440-6302RB is rated at 1.75A per contact, which exceeds the 1A requirement. This part is suitable for applications requiring 1A or less. The higher current rating provides additional design margin. However, verify that other electrical parameters (voltage rating not specified for this part) meet your application requirements before selection.

Q: Which substitute part is closest to the original 2-5102321-7?

A: The 3M N3440-6303RB provides the closest mechanical match, with identical contact post length (0.155"), identical mating contact length (0.240"), and nearly identical overall contact length (0.695" versus 0.684"). The TE Connectivity 5499206-7 maintains the same series designation and insulation height but features a shorter contact post length (0.110"). Selection depends on whether series continuity or exact mechanical dimensions are prioritized for your application.
