Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2-87579-2 with the 7-87579-2 is based on strict equivalence across all critical electrical and mechanical parameters. Both parts share identical specifications for connector type, contact configuration, pitch spacing, mounting orientation, shrouding design, termination method, contact material, insulation material, operating temperature range, current rating, flammability rating, and moisture sensitivity level.

The primary differences between these parts are:

Product Status: The 2-87579-2 is obsolete, while the 7-87579-2 is active.

Contact Finish - Mating and Post: The 2-87579-2 uses Tin-Lead finish, while the 7-87579-2 uses Tin finish.

RoHS Compliance: The 2-87579-2 is RoHS non-compliant, while the 7-87579-2 is ROHS3 compliant.

Packaging: The 2-87579-2 packaging is unspecified, while the 7-87579-2 is supplied in Tray packaging.

These differences do not affect functional compatibility or electrical performance within the specified operating parameters.

Parameter Comparison

Engineering Selection Recommendations

The 7-87579-2 is the direct substitute for the obsolete 2-87579-2. Selection of the 7-87579-2 is appropriate for applications requiring:

Active Product Status: The 7-87579-2 maintains current manufacturing and supply chain support, eliminating obsolescence risk associated with the 2-87579-2.

RoHS3 Compliance: The 7-87579-2 meets ROHS3 compliance requirements, making it suitable for applications and markets with regulatory mandates for lead-free or restricted substance compliance. The 2-87579-2 does not meet these requirements.

Functional Equivalence: Both parts maintain identical electrical and mechanical specifications across all critical parameters including connector type, contact configuration, pitch spacing, mounting orientation, shrouding, termination method, contact material, insulation material, operating temperature range, and current rating.

Contact Finish Consideration: The 7-87579-2 uses Tin finish instead of Tin-Lead. This change reflects industry-wide transition to lead-free materials and does not affect electrical performance or mechanical compatibility within the specified operating parameters.

Packaging: The 7-87579-2 is supplied in Tray packaging, providing standardized handling and storage for production environments.

Frequently Asked Questions (FAQ)

Q: Can the 7-87579-2 directly replace the 2-87579-2 in existing designs?

A: Yes. The 7-87579-2 is functionally equivalent to the 2-87579-2 across all critical electrical and mechanical parameters. Both connectors share identical specifications for connector type, contact configuration, pitch spacing, mounting orientation, shrouding, termination method, contact material, insulation material, operating temperature range, and current rating. The parts are mechanically and electrically interchangeable.

Q: What is the difference between Tin-Lead and Tin contact finishes?

A: The 2-87579-2 uses Tin-Lead contact finish, while the 7-87579-2 uses Tin finish. This difference reflects the industry transition to lead-free materials. Both finishes provide equivalent electrical conductivity and contact reliability within the specified operating parameters. The Tin finish on the 7-87579-2 supports RoHS3 compliance requirements.

Q: Why is the 2-87579-2 classified as obsolete?

A: The 2-87579-2 is obsolete due to its RoHS non-compliant status and the availability of the active equivalent 7-87579-2. The 7-87579-2 provides the same functionality with current manufacturing support and regulatory compliance.

Q: Does the change from Tin-Lead to Tin finish affect performance?

A: No. Both contact finishes provide equivalent electrical performance and mechanical reliability within the specified operating temperature range of -65°C to 105°C and current rating of 3A. The change to Tin finish on the 7-87579-2 reflects compliance with lead-free material standards.

Q: What is the significance of RoHS3 compliance?

A: RoHS3 compliance indicates that the 7-87579-2 meets Restriction of Hazardous Substances regulations, restricting the use of lead and other hazardous materials. This compliance is required for many applications and markets, particularly in Europe and for products subject to environmental regulations.

Q: Are there any packaging differences between these parts?

A: Yes. The 2-87579-2 has unspecified packaging, while the 7-87579-2 is supplied in Tray packaging. Tray packaging provides standardized handling, storage, and automated assembly compatibility for production environments.

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

A: Both parts have an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions. These connectors can be stored and handled under standard conditions without special moisture control measures.

Q: Are both parts from the same manufacturer?

A: Yes. Both the 2-87579-2 and 7-87579-2 are manufactured by TE Connectivity AMP Connectors and are part of the AMPMODU Mod II series.
