Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0878341641 is determined by strict adherence to the following core parameters:

Connector type, contact type, and gender (Header, Male Pin)
Position count and row configuration (16 positions, 2 rows)
Mating pitch and row spacing (0.100" / 2.54mm)
Shrouding style (Shrouded - 4 Wall)
Mounting method (Through Hole)
Termination type (Solder)

Engineering Selection Recommendations

Primary Equivalent (RoHS3 Compliant, REACH Unaffected):

3M N2516-6002-RB and 3M N2516-6003-RB are the preferred substitutes for the Molex 0878341641. Both parts maintain ROHS3 compliance and REACH unaffected status, matching the regulatory profile of the original part. The N2516-6002-RB features a contact post length of 0.112" (2.84mm), while the N2516-6003-RB provides an extended post length of 0.155" (3.94mm) for applications requiring deeper board penetration. Both are available in bulk packaging with 2,302 and 1,845 units in stock respectively.

Secondary Equivalent (RoHS Compliant, REACH Unaffected):

TE Connectivity 5103308-3 is a RoHS compliant alternative with REACH unaffected status. This part is packaged in trays with 2,388 units in stock and offers compatibility with the original specification. The contact post length is 0.120" (3.05mm).

Alternative with Extended Operating Temperature:

3M D2516-6002-AR provides an extended operating temperature range of -55°C to 105°C compared to the standard -65°C to 105°C range. This part is RoHS compliant and REACH unaffected, with a current rating of 1.75A per contact and 979 units available in tray packaging.

Non-Compliant Alternatives (Regulatory Considerations Required):

TE Connectivity 103308-3 and 103309-3 are RoHS non-compliant and REACH affected. These parts are suitable only for applications where regulatory exemptions apply or where legacy component specifications are mandated. The 103308-3 is available in bulk (863 units), while the 103309-3 is supplied in tubes (1,246 units).

Frequently Asked Questions (FAQ)

Q: Can I substitute the Molex 0878341641 with any of the listed parts without design modification?

A: Yes, all listed substitute parts maintain the same connector type, position count, pitch spacing, shrouding configuration, and mounting method. No PCB layout or mating connector modifications are required. However, verify contact post length compatibility with your specific board thickness and application requirements.

Q: What is the difference between the 3M N2516-6002-RB and N2516-6003-RB?

A: Both parts are functionally equivalent with identical electrical and mechanical specifications. The primary difference is contact post length: the N2516-6002-RB has a 0.112" (2.84mm) post, while the N2516-6003-RB has a 0.155" (3.94mm) post. Select based on your PCB thickness and solder joint depth requirements.

Q: Are the TE Connectivity 103308-3 and 103309-3 suitable for new designs?

A: Both parts are active products with adequate inventory. However, they are RoHS non-compliant and REACH affected. Use these parts only if your application has specific regulatory exemptions or if legacy component specifications mandate their use. For new designs, prioritize RoHS3 compliant alternatives such as the 3M N2516 series or TE 5103308-3.

Q: What packaging options are available for these substitute parts?

A: Substitute parts are supplied in three packaging formats: Tray (Molex 0878341641, TE 5103308-3, 3M D2516-6002-AR), Bulk (TE 103308-3, 3M N2516-6002-RB, 3M N2516-6003-RB), and Tube (TE 103309-3). Packaging does not affect electrical or mechanical compatibility; select based on your procurement and assembly process requirements.

Q: Does contact material composition affect compatibility?

A: All substitute parts feature either copper alloy or brass contact materials with gold or gold-palladium mating finishes and tin or tin-lead post finishes. These material combinations are functionally equivalent for standard through-hole solder applications. Contact material differences do not impact mating performance or electrical characteristics.

Q: What is the current rating for these connectors?

A: The Molex 0878341641 does not specify a current rating in the provided data. TE Connectivity parts (103308-3, 103309-3, 5103308-3) are rated at 1A per contact. The 3M D2516-6002-AR is rated at 1.75A per contact. The 3M N2516 series does not specify a current rating. Verify current requirements against your application specifications.

Q: Are there operating temperature differences I should consider?

A: The Molex 0878341641 does not specify an operating temperature range. TE Connectivity AMP-Latch parts (103308-3, 103309-3, 5103308-3) operate from -65°C to 105°C. The 3M D2516-6002-AR operates from -55°C to 105°C, providing a narrower low-temperature range. The 3M N2516 series does not specify an operating temperature range. Select based on your thermal environment requirements.
