Substitute Part Grouping Explanation

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

Connector type, contact type, and position count (34 positions, 2 rows)
Mating pitch and row spacing (0.100" / 2.54mm)
Shrouding configuration (Shrouded - 4 Wall)
Mounting method (Through Hole) and termination (Solder)
Fastening mechanism (Push-Pull)
Contact shape (Square)
Material flammability rating (UL94 V-0)
Moisture sensitivity level (MSL 1)

All identified substitute parts meet these core electrical and mechanical parameters. Variations in contact finish thickness, insulation material composition, contact length specifications, and packaging format are permitted within the substitution scope. Compliance status differences (RoHS, REACH) are noted but do not preclude substitution eligibility based on electrical and mechanical compatibility.

Engineering Selection Recommendations

All substitute parts listed maintain active product status and meet the core electrical and mechanical specifications of the Molex 0878343441. Selection among substitutes should be based on the following criteria:

RoHS Compliance Requirements: The Molex 0878343441, 3M 30334-6002HB, TE 5103308-7, 3M N2534-6002-RB, and 3M N2534-6003-RB are ROHS3 compliant. The TE Connectivity parts 103308-7 and 103309-7 are RoHS non-compliant and should be selected only when RoHS compliance is not a design requirement.

Packaging Format: Selection depends on procurement and assembly workflow. Bulk packaging (Molex 0878343441, TE 103308-7, 3M 30334-6002HB, 3M N2534-6002-RB, 3M N2534-6003-RB) suits high-volume applications. Tube packaging (TE 103309-7) and tray packaging (TE 5103308-7) accommodate alternative handling and storage requirements.

Contact Material and Finish: Molex 0878343441 and 3M parts use copper alloy contacts, while TE Connectivity parts use brass contacts. All parts feature gold-plated mating surfaces suitable for general purpose, automotive, lighting, medical, and telecommunications applications.

Operating Temperature Range: TE Connectivity parts (103308-7, 103309-7, 5103308-7) specify -65°C to 105°C. The 3M parts (30334-6002HB, N2534-6002-RB, N2534-6003-RB) specify -55°C to 105°C. The Molex 0878343441 does not specify an operating temperature range in the provided data.

Frequently Asked Questions (FAQ)

Q: Can TE Connectivity 103308-7 and 103309-7 be used as direct substitutes despite RoHS non-compliance?

A: Yes, from an electrical and mechanical standpoint. However, design requirements and regulatory obligations must be evaluated. If RoHS3 compliance is mandatory, select from Molex 0878343441, 3M 30334-6002HB, TE 5103308-7, 3M N2534-6002-RB, or 3M N2534-6003-RB.

Q: What is the difference between TE 103308-7 and TE 103309-7?

A: Both are electrically and mechanically equivalent. The primary difference is packaging format: 103308-7 is supplied in bulk, while 103309-7 is supplied in tube format. Contact finish thickness on mating surfaces also differs (15.0µin versus 30.0µin).

Q: Are there differences in contact post length among the substitutes?

A: Yes. The Molex 0878343441 specifies 0.135" (3.43mm) post length. TE Connectivity parts specify 0.120" (3.05mm). The 3M 30334-6002HB specifies 0.110" (2.79mm), while 3M N2534-6002-RB and N2534-6003-RB specify 0.112" (2.84mm) and 0.155" (3.94mm) respectively. These variations may affect PCB design and solder joint geometry.

Q: Which substitute offers the highest current rating?

A: The 3M N2534-6002-RB and N2534-6003-RB both support 1.75A per contact, compared to 1A per contact for TE Connectivity parts. The Molex 0878343441 does not specify a current rating in the provided data.

Q: Can I mix different substitute parts in the same assembly?

A: All parts are mechanically compatible due to identical pitch, position count, and shrouding configuration. However, assembly consistency and supply chain traceability should be considered for production environments.

Q: What packaging quantity considerations apply?

A: Inventory levels vary by part and packaging format. Bulk packaging typically accommodates higher-volume procurement. Tube and tray formats may be preferred for smaller production runs or when component handling automation differs from bulk processing.
