Key Parameters

Substitute Part Grouping Explanation

Substitution between the 794069-2 and 1-794069-1 is based on electrical and mechanical parameter equivalence within the Mini-Universal MATE-N-LOK series. Both parts maintain identical specifications for the following critical parameters:

• Connector type, contact type, and gender (Header, Male Pin)
• Position count and row configuration (18 positions, 2 rows)
• Mating pitch and row spacing (0.163" / 4.14mm)
• Mounting method and termination type (Through Hole, Solder)
• Shrouding configuration (Shrouded - 4 Wall)
• Fastening mechanism (Locking Ramp)
• Electrical ratings (600VAC, -20°C ~ 105°C)
• Flammability compliance (UL94 V-0)
• Contact material and geometry (Brass, Circular)
• Insulation material and color (Polyamide/Nylon, White)

Differences between these parts are limited to packaging format and post-contact finish specifications, which do not affect functional interchangeability in equivalent circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the 794069-2 and 1-794069-1 are active products from TE Connectivity within the Mini-Universal MATE-N-LOK series and are functionally equivalent for board-to-cable/wire connector applications requiring 18-position, 2-row through-hole headers with 0.163" pitch spacing.

The 1-794069-1 is ROHS3 compliant, whereas the 794069-2 is RoHS non-compliant. Applications subject to RoHS3 regulatory requirements must use the 1-794069-1 variant.

The 794069-2 features tin-lead post contact finish, while the 1-794069-1 features tin post contact finish. Both maintain identical mating contact finish (gold) and thickness specifications. Post contact finish differences do not affect mating performance but may influence soldering characteristics and long-term reliability in specific environmental conditions.

The 1-794069-1 is supplied in bulk packaging, whereas the 794069-2 packaging format is standard. Packaging selection depends on procurement volume and inventory management requirements.

Frequently Asked Questions (FAQ)

Q: Are the 794069-2 and 1-794069-1 mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications including pitch (0.163"), row spacing (0.163"), number of positions (18), mounting type (through hole), shrouding configuration (4-wall), and overall dimensions. They are mechanically interchangeable in equivalent circuit applications.

Q: What is the primary difference between these two parts?

A: The primary differences are RoHS compliance status and post contact finish. The 1-794069-1 is ROHS3 compliant with tin post finish, while the 794069-2 is RoHS non-compliant with tin-lead post finish. Both maintain identical mating contact specifications (gold, 30.0µin thickness).

Q: Which part should be selected for RoHS-regulated applications?

A: The 1-794069-1 must be used for applications subject to RoHS3 regulatory requirements, as it carries ROHS3 compliant certification. The 794069-2 is not RoHS compliant and is unsuitable for such applications.

Q: Do the different post contact finishes affect electrical performance?

A: Post contact finish does not affect mating electrical performance, as mating occurs through the gold-plated mating contacts on both parts. Post finish differences may influence soldering characteristics and long-term reliability in specific environmental or thermal cycling conditions.

Q: Are there packaging differences between these parts?

A: Yes. The 1-794069-1 is supplied in bulk packaging, while the 794069-2 uses standard packaging. Packaging format does not affect connector functionality and is selected based on procurement volume and inventory management requirements.

Q: What is the operating temperature range for both parts?

A: Both the 794069-2 and 1-794069-1 operate across the identical temperature range of -20°C to 105°C and maintain UL94 V-0 flammability compliance across this range.

Q: Can these connectors be used in applications requiring 600VAC operation?

A: Yes. Both parts carry a 600VAC voltage rating and are suitable for general-purpose applications within this electrical specification.
