Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0878341611 is determined by strict alignment of the following critical parameters:

• Connector Type & Contact Configuration: Header with male pin contacts
• Position Count & Row Configuration: 16 positions in 2-row arrangement
• Pitch Specification: 0.100" (2.54mm) mating pitch and row spacing
• Mounting & Termination: Through-hole solder termination
• Shrouding & Fastening: Shrouded 4-wall design with push-pull fastening
• Contact Shape: Square contact geometry
• Flammability & Moisture Sensitivity: UL94 V-0 rating and MSL 1 classification

All three substitute parts (TE Connectivity 103308-3, TE Connectivity 103309-3, and 3M N2516-6003-RB) meet these core substitution criteria. Variations in contact finish thickness, insulation material composition, contact length specifications, and operating temperature ranges represent acceptable parameter differences within the rectangular connector category and do not preclude functional substitution in applications where the main part is specified.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts maintain active product status and UL94 V-0 flammability certification, establishing baseline compatibility with the Molex 0878341611 for rectangular connector applications requiring 16-position, 2.54mm pitch through-hole headers.

TE Connectivity 103308-3 (Bulk Packaging): This part aligns with the Molex specification across all critical connector parameters. The AMP-Latch series provides equivalent mechanical and electrical performance. RoHS non-compliance status requires evaluation against project-specific regulatory requirements. Operating temperature range of -65°C to 105°C supports standard industrial applications.

TE Connectivity 103309-3 (Tube Packaging): Functionally identical to 103308-3 with increased contact finish thickness on mating surfaces (30.0µin versus 15.0µin). Tube packaging accommodates automated assembly workflows. RoHS non-compliance status applies identically to 103308-3. This variant is suitable for high-volume production environments where packaging format impacts assembly efficiency.

3M N2516-6003-RB (Bulk Packaging): This part maintains ROHS3 compliance and REACH unaffected status, aligning with the Molex regulatory profile. The 2500 series offers the highest current rating (1.75A per contact) and extended operating temperature range (-55°C to 105°C). Contact post finish thickness (200.0µin) exceeds both the main part and TE Connectivity alternatives, providing enhanced durability in high-cycle mating applications.

Selection between substitutes depends on regulatory compliance requirements, operating environment specifications, and packaging logistics. All three parts satisfy the core mechanical and electrical substitution criteria for the Molex 0878341611.

Frequently Asked Questions (FAQ)

Q: What determines whether a part can substitute for the Molex 0878341611?

A: Substitution eligibility requires matching the following parameters: 16-position, 2-row header configuration with 0.100" (2.54mm) pitch spacing, male pin contacts, through-hole solder termination, shrouded 4-wall design, push-pull fastening, square contact geometry, and UL94 V-0 flammability rating. All three listed substitutes meet these criteria.

Q: Are there differences in contact material between the main part and substitutes?

A: Yes. The Molex 0878341611 uses copper alloy contacts, while both TE Connectivity parts (103308-3 and 103309-3) use brass contacts. The 3M N2516-6003-RB returns to copper alloy. These material variations are acceptable within rectangular connector specifications and do not affect functional substitution in standard applications.

Q: What is the significance of contact finish thickness variations?

A: Contact finish thickness affects durability in high-cycle mating environments. The Molex part specifies 5.11µin (0.130µm) mating finish. TE Connectivity 103308-3 provides 15.0µin (0.38µm), 103309-3 provides 30.0µin (0.76µm), and 3M N2516-6003-RB provides 30.0µin (0.76µm). Thicker finishes extend contact life in applications with frequent mating cycles.

Q: How do packaging formats affect part selection?

A: The Molex 0878341611 and most substitutes ship in bulk packaging. TE Connectivity 103309-3 is available in tube packaging, which integrates with automated pick-and-place assembly systems. Packaging selection depends on manufacturing process requirements and does not affect electrical or mechanical performance.

Q: What are the regulatory compliance differences?

A: The Molex 0878341611 and 3M N2516-6003-RB are ROHS3 compliant and REACH unaffected. TE Connectivity 103308-3 and 103309-3 are RoHS non-compliant and REACH affected. Projects with regulatory requirements for RoHS3 compliance should prioritize the Molex or 3M alternatives.

Q: Do operating temperature ranges affect substitution decisions?

A: The Molex 0878341611 does not specify an operating temperature range. TE Connectivity parts operate from -65°C to 105°C. The 3M N2516-6003-RB operates from -55°C to 105°C. For applications requiring extended low-temperature performance, TE Connectivity parts provide broader specification coverage.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, within the constraints of the specified parameters. All parts share identical pitch, position count, row configuration, mounting type, and shrouding. Mechanical fit and electrical performance are equivalent. Design validation should confirm that variations in contact material, finish thickness, and operating temperature do not conflict with application-specific requirements.
