Engineering Selection Recommendations

All nine parts listed—the original Molex 0010892346 and the eight substitute options—share identical core electrical and mechanical specifications required for direct substitution in 34-position, 2.54mm pitch through-hole right-angle connector applications. Selection among active alternatives should prioritize the following factors:

Product Status Advantage: All substitute parts carry Active product status, ensuring long-term availability and manufacturing continuity. The original Molex part is classified as Obsolete, making substitution necessary for new production and ongoing supply chain management.

Compliance and Certification: All parts meet UL94 V-0 flammability requirements and MSL 1 moisture sensitivity specifications. RoHS compliance is confirmed across all substitutes, with Preci-Dip and Harwin options offering ROHS3 Compliant status matching the original part. REACH compliance varies: Amphenol ICC and Harwin parts are REACH Affected; Preci-Dip and 3M options are REACH Unaffected or REACH Affected as specified.

Inventory Availability: Current stock levels range from 801 to 1,403 pieces across substitute options, providing adequate supply for production requirements.

Contact Geometry Variations: Minor differences in contact length (mating and post) and insulation height exist across substitutes. These variations fall within acceptable mechanical tolerances for standard PCB assembly processes. The Preci-Dip 802-10-034-20-001101 features circular contacts rather than square; this represents a geometric variation that may affect insertion force characteristics but maintains electrical compatibility.

Contact Finish Considerations: The original part specifies gold mating finish at 30.0µin thickness. Amphenol ICC 68021-134HLF matches this specification exactly. Other substitutes offer gold finishes at varying thicknesses (15.0µin, Flash) or tin finishes (Harwin M20-9741746). All finishes provide adequate corrosion protection for standard applications.

Operating Temperature Range: The original part does not specify an operating temperature range. Substitute parts range from -25°C to -65°C minimum and 105°C to 130°C maximum. For applications requiring extended temperature performance, Amphenol ICC 77317 series and Preci-Dip options support -65°C to 130°C or -55°C to 125°C respectively.

Current and Voltage Ratings: Most substitutes specify 3A per contact current rating. The 3M 961234-5804-AR specifies 2A per contact. Voltage ratings are specified for Amphenol ICC 68021-134HLF (110V), Preci-Dip options (150VDC), and not specified for others. For applications requiring voltage isolation or higher current capacity, Preci-Dip parts offer 150VDC rating.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts as a direct replacement for the Molex 0010892346?

A: Yes. All eight substitute parts meet the core compatibility requirements: 34 positions, 2.54mm pitch, 2-row configuration, through-hole right-angle mounting, male pin contacts, solder termination, push-pull fastening, unshrouded design, and UL94 V-0 flammability rating. Minor variations in contact length, insulation height, and contact finish do not affect functional compatibility in standard board-to-board applications.

Q: What is the difference between the Amphenol ICC BERGSTIK® II series (68020-234HLF, 68021-134HLF) and BERGSTIK® series (77317-804-34LF, 77317-812-34LF)?

A: Both series meet the core 34-position 2.54mm pitch specification. The BERGSTIK® II series (68020, 68021) offers operating temperature range of -65°C to 125°C. The BERGSTIK® series (77317) extends to -65°C to 130°C and features breakaway connector type. Contact length variations exist: BERGSTIK® II mating contact length is 0.230" (5.84mm); BERGSTIK® 77317-812-34LF extends to 0.268" (6.80mm). Selection depends on specific PCB thickness and thermal environment requirements.

Q: Why does the Preci-Dip 802-10-034-20-001101 have circular contacts while others have square contacts?

A: Contact shape is a geometric variation that does not affect electrical compatibility. Circular contacts in the Preci-Dip 802 series provide equivalent contact area and current-carrying capacity (3A) as square contacts in other parts. Insertion force and mating feel may differ slightly, but mechanical and electrical performance remain equivalent for standard applications.

Q: Which substitute offers the best long-term availability?

A: All substitute parts carry Active product status, ensuring manufacturing continuity. Amphenol ICC (FCI), Preci-Dip, Harwin, and 3M are established connector manufacturers with established supply chains. For critical applications requiring extended availability assurance, consult directly with the selected manufacturer regarding long-term product roadmap commitments.

Q: What is the difference between ROHS3 Compliant and RoHS Compliant status?

A: ROHS3 Compliant indicates compliance with the most recent RoHS 3 directive (2015/863/EU), which includes restrictions on phthalates in addition to the original six restricted substances. RoHS Compliant indicates compliance with the original RoHS directive. Both statuses confirm restriction of hazardous substances. For applications requiring the most current environmental compliance, ROHS3 Compliant parts (Molex original, Preci-Dip, Harwin) are preferred.

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

A: Yes, provided all parts meet the core compatibility requirements listed in the Substitute Part Grouping Explanation section. However, for manufacturing consistency and supply chain simplification, using a single part number across an assembly is recommended.

Q: What packaging options are available?

A: Amphenol ICC 68020-234HLF is supplied in Bag packaging. Amphenol ICC 77317 series, Preci-Dip, and Harwin parts are supplied in Bulk packaging. Packaging does not affect component performance; selection depends on inventory management and assembly process requirements.

Q: Which substitute part most closely matches the original Molex 0010892346 specifications?

A: Amphenol ICC 68021-134HLF provides the closest match: identical 34-position, 2.54mm pitch, 2-row configuration, contact length mating specification of 0.230" (5.84mm) versus original 0.240" (6.10mm), matching contact finish thickness of 30.0µin (0.76µm), and equivalent insulation height of 0.190" (4.83mm) versus original 0.200" (5.08mm). This part is recommended as the primary substitute for applications requiring minimal design modification.
