Substitute Part Grouping Explanation

Substitution between the main part number 1-794632-4 and the equivalent part 4-794632-4 is based on identical electrical and mechanical specifications within the Micro MATE-N-LOK series. Both parts share the following critical parameters that determine functional interchangeability:

Electrical Compatibility:

• 14-position configuration with 2-row layout
• 0.118" (3.00mm) mating pitch and row spacing
• 250V voltage rating
• Male pin contact type
• Gold-plated mating contacts (30.0µin thickness)

Mechanical Compatibility:

• Through-hole mounting with press-fit and solder termination
• Shrouded 4-wall design
• 0.125" (3.18mm) post contact length
• 0.364" (9.25mm) insulation height
• Square contact shape
• Brass contact material with polyamide/nylon insulation
• UL94 V-0 flammability rating
• -40°C to 105°C operating temperature range

Packaging Distinction: The primary difference between these parts is packaging format. The 1-794632-4 is supplied in standard packaging, while the 4-794632-4 is supplied in tray packaging. This distinction affects inventory management and bulk handling but does not alter electrical or mechanical performance.

Compliance Variation: The 4-794632-4 carries RoHS Compliant status, whereas the 1-794632-4 is RoHS non-compliant. This distinction is significant for applications subject to RoHS directives.

Parameter Comparison

Engineering Selection Recommendations

Both the 1-794632-4 and 4-794632-4 are active products from TE Connectivity within the Micro MATE-N-LOK series and are electrically and mechanically interchangeable for board-to-cable/wire connection applications. Selection between these parts should be based on the following criteria:

RoHS Compliance Requirements: Applications subject to RoHS directives must use the 4-794632-4, which carries RoHS Compliant certification. The 1-794632-4 is RoHS non-compliant and is unsuitable for regulated markets or end-use applications requiring RoHS compliance.

Packaging and Inventory Considerations: The 4-794632-4 is supplied in tray packaging with higher inventory availability (2644 units) compared to the 1-794632-4 (1075 units). Tray packaging is standard for high-volume production environments and automated assembly processes.

Contact Finish Specification: The 1-794632-4 features tin-lead post contact finish, while the 4-794632-4 features tin post contact finish. Both finishes are compatible with press-fit and solder termination methods. The tin-lead finish in the 1-794632-4 reflects its non-RoHS status, whereas the tin finish in the 4-794632-4 aligns with RoHS compliance requirements.

Product Status: Both parts maintain active product status with TE Connectivity, ensuring continued availability and technical support.

Frequently Asked Questions (FAQ)

Q: Are the 1-794632-4 and 4-794632-4 electrically interchangeable?

A: Yes. Both parts share identical electrical specifications including 14-position configuration, 0.118" (3.00mm) pitch, 250V voltage rating, and male pin contact type with gold-plated mating surfaces. They are electrically interchangeable in all applications.

Q: Are the 1-794632-4 and 4-794632-4 mechanically interchangeable?

A: Yes. Both parts feature identical mechanical specifications including through-hole mounting, shrouded 4-wall design, 0.125" (3.18mm) post contact length, and -40°C to 105°C operating temperature range. They are mechanically interchangeable in all board layouts and assembly processes.

Q: What is the primary difference between these two part numbers?

A: The primary differences are packaging format and RoHS compliance status. The 1-794632-4 uses standard packaging and is RoHS non-compliant. The 4-794632-4 uses tray packaging and is RoHS Compliant. Additionally, the post contact finish differs: tin-lead for the 1-794632-4 and tin for the 4-794632-4.

Q: Which part should I select for RoHS-regulated applications?

A: The 4-794632-4 must be used for applications subject to RoHS directives. It carries RoHS Compliant certification, whereas the 1-794632-4 is RoHS non-compliant and unsuitable for regulated markets.

Q: Does the tray packaging of the 4-794632-4 affect performance?

A: No. Tray packaging is a logistics and handling format that does not affect electrical or mechanical performance. The 4-794632-4 in tray packaging performs identically to the 1-794632-4 in standard packaging.

Q: Can I use the 1-794632-4 in place of the 4-794632-4?

A: Electrical and mechanical substitution is possible; however, RoHS compliance status must be verified for your application. If RoHS compliance is required, the 1-794632-4 is not suitable. If RoHS compliance is not required, the 1-794632-4 is functionally equivalent.

Q: Can I use the 4-794632-4 in place of the 1-794632-4?

A: Yes. The 4-794632-4 is a direct substitute for the 1-794632-4 in all applications. It provides superior compliance status (RoHS Compliant) and higher inventory availability.

Q: Are there any termination differences between these parts?

A: No. Both parts support identical termination methods: press-fit and solder. The contact finish variation (tin-lead versus tin) does not affect termination compatibility.

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

A: Both the 1-794632-4 and 4-794632-4 operate across -40°C to 105°C, making them suitable for industrial and commercial temperature environments.

Q: Are both parts UL94 V-0 rated?

A: Yes. Both parts carry UL94 V-0 material flammability rating, meeting fire safety requirements for general-purpose electronic applications.
