Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 4-794636-0 is a direct functional equivalent to the obsolete 1-794636-0. Selection of the substitute part is based on the following engineering criteria:

Product Status Consideration: The main part 1-794636-0 carries an Obsolete status, indicating discontinued manufacturing and limited long-term availability. The substitute 4-794636-0 maintains Active product status, ensuring ongoing manufacturing support and supply chain continuity.

Compliance & Certification: The substitute part 4-794636-0 is RoHS Compliant, whereas the main part status is Not applicable. This compliance upgrade aligns with current regulatory requirements for electronic components in many jurisdictions and applications.

Contact Finish Specification: The main part features Tin-Lead contact finish, while the substitute uses Tin (lead-free) finish. Both specifications maintain identical contact finish thickness of 100.0µin (2.54µm) and are functionally compatible for solder termination applications.

Packaging Format: The main part is supplied in bulk packaging, while the substitute is supplied in Tape & Reel (TR) format. The TR format is standard for automated assembly processes and provides improved component handling and traceability.

Electrical & Mechanical Equivalence: All critical electrical parameters (250V voltage rating, -40°C ~ 105°C operating temperature range) and mechanical parameters (10-position, 2-row, 0.118" pitch, surface mount, shrouded 4-wall configuration) are identical between the main part and substitute.

Frequently Asked Questions (FAQ)

Q: Can the 4-794636-0 be used as a direct replacement for the 1-794636-0 in existing designs?

A: Yes. The 4-794636-0 maintains full electrical and mechanical equivalence to the 1-794636-0. All critical parameters including connector type, position count, pitch, mounting method, voltage rating, and operating temperature range are identical. The primary differences are product status (Active vs. Obsolete), packaging format (Tape & Reel vs. Bulk), and contact finish specification (Tin vs. Tin-Lead).

Q: What is the significance of the contact finish change from Tin-Lead to Tin?

A: The contact finish change reflects the industry transition to lead-free materials. Both finishes provide equivalent electrical and mechanical performance for solder termination applications. The Tin finish on the substitute part meets RoHS compliance requirements while maintaining the same contact finish thickness of 100.0µin (2.54µm).

Q: Why is the substitute part supplied in Tape & Reel format?

A: Tape & Reel (TR) packaging is the standard format for automated surface mount assembly processes. This format improves component handling efficiency, reduces manual labor, and provides enhanced traceability compared to bulk packaging. The physical connector itself is identical regardless of packaging format.

Q: Are there any compatibility issues with PCB assembly equipment?

A: No. Both the main part and substitute are surface mount connectors with identical mechanical dimensions and mounting specifications. The Tape & Reel format of the substitute is compatible with standard pick-and-place assembly equipment.

Q: What does the RoHS Compliant status of the substitute part mean?

A: RoHS Compliance indicates that the substitute part 4-794636-0 meets the Restriction of Hazardous Substances directive requirements, restricting the use of specific hazardous materials including lead, mercury, cadmium, and certain brominated flame retardants. This compliance status is required for many applications and markets, particularly in consumer electronics and regulated industries.

Q: Are the electrical performance characteristics identical between the two parts?

A: Yes. Both parts share identical voltage rating (250V), operating temperature range (-40°C ~ 105°C), current rating specification (Varies by Wire Gauge), and material flammability rating (UL94 V-0). Electrical performance is fully equivalent.

Q: Can I mix the 1-794636-0 and 4-794636-0 in the same production run?

A: While both parts are functionally equivalent, mixing different part numbers in production is not recommended from a traceability and quality control perspective. Standardization on the active substitute part 4-794636-0 is the preferred approach for new designs and ongoing production.

Q: What is the Moisture Sensitivity Level (MSL) rating?

A: Both parts carry an MSL rating of 1 (Unlimited), indicating no moisture sensitivity. These connectors do not require special moisture control handling during storage, transportation, or assembly.
