Key Parameters

Substitute Part Grouping Explanation

Substitution for the 76342-302 is determined by strict equivalence across the following critical parameters:

• Connector type (Receptacle)
• Contact type (Female Socket)
• Number of positions (4)
• Pitch spacing (0.100" / 2.54mm)
• Row configuration (2 rows at 0.100" spacing)
• Mounting method (Through Hole)
• Termination type (Solder)
• Fastening mechanism (Push-Pull)
• Contact finish specification (Gold mating surface)
• Insulation material and flammability rating (UL94 V-0)

The 76342-302LF meets all these criteria and is identified as a direct substitute. The primary distinction between the main part and its substitute relates to product status, packaging format, and regulatory compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The 76342-302LF serves as the direct functional equivalent to the obsolete 76342-302. Both parts share identical electrical and mechanical specifications across all critical connector parameters, including pitch, contact configuration, termination method, and physical dimensions.

The primary differentiators are regulatory and availability factors:

• The 76342-302LF holds Active product status, ensuring ongoing manufacturer support and availability, whereas the 76342-302 is Obsolete.
• The 76342-302LF is RoHS Compliant, meeting current environmental regulations for new designs and procurement cycles.
• The 76342-302LF is REACH Affected, indicating compliance with chemical substance regulations.
• The 76342-302LF is supplied in Bulk packaging with significantly higher inventory availability (3472 units versus 645 units).

For applications requiring RoHS compliance or long-term component availability, the 76342-302LF is the appropriate selection. For legacy systems where RoHS non-compliant components are acceptable, the 76342-302 remains functionally equivalent.

Frequently Asked Questions (FAQ)

Q: Are the 76342-302 and 76342-302LF mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications, including pitch (0.100"), row spacing (0.100"), mounting type (through-hole), contact geometry, and mated stacking height (11.04mm). They are direct mechanical substitutes.

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

A: There is no functional difference. Both parts are 4-position receptacle connectors with identical electrical and mechanical characteristics. The differences are regulatory compliance status and product lifecycle stage.

Q: Why does the 76342-302LF have "LF" in its part number?

A: The "LF" designation indicates Lead-Free compliance, which correlates with the RoHS Compliant status of the 76342-302LF. The original 76342-302 is RoHS non-compliant.

Q: Can I use the 76342-302LF as a replacement in existing designs using the 76342-302?

A: Yes. The 76342-302LF is a direct substitute with identical specifications. No design modifications are required for PCB layout, mating connector selection, or electrical performance.

Q: What packaging options are available?

A: The 76342-302 packaging is not specified in available documentation. The 76342-302LF is supplied in Bulk packaging format.

Q: Are there any compliance considerations when switching from 76342-302 to 76342-302LF?

A: The 76342-302LF is RoHS Compliant and REACH Affected, making it suitable for applications subject to environmental regulations. The original 76342-302 is RoHS non-compliant and REACH Unaffected. For new designs or regulated applications, the 76342-302LF is the appropriate choice.

Q: What is the contact finish specification for both parts?

A: Both parts feature gold-plated mating contacts (30.0µin / 0.76µm thickness) and tin-plated posts (78.7µin / 2.00µm thickness). Contact material is phosphor bronze for both.
