Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 88945-302 is determined by strict equivalence across the following critical parameters:

• Connector type and gender (Receptacle, Female Sockets)
• Position count (24 positions)
• Contact pitch (0.079" / 2.00mm)
• Row configuration (4 rows)
• Mounting method (Board Edge, Through Hole, Right Angle)
• Termination technology (Press-Fit)
• Electrical ratings (1A current, 1000V voltage)
• Operating temperature range (-55°C to 105°C)
• Flammability compliance (UL94 V-0)
• Series designation (Metral® B)

The substitute part 88945-302LF maintains identical electrical, mechanical, and environmental specifications as the main part. The primary distinction is product status and regulatory compliance posture.

Parameter Comparison

Engineering Selection Recommendations

The 88945-302LF is the direct substitute for the obsolete 88945-302. Both parts are manufactured by Amphenol ICC and belong to the Metral® B series with identical electrical, mechanical, and environmental specifications.

The 88945-302LF offers the following advantages:

• Active product status ensures ongoing manufacturer support and availability
• RoHS compliance satisfies modern regulatory requirements for new designs and production
• Tube packaging provides organized component handling and inventory management

Selection of the 88945-302LF is appropriate for applications requiring equivalent performance to the original 88945-302 while maintaining compliance with current environmental and supply chain standards.

Frequently Asked Questions (FAQ)

Q: Can the 88945-302LF directly replace the 88945-302 in existing designs?

A: Yes. The 88945-302LF maintains identical electrical ratings (1A, 1000V), mechanical configuration (24-position, 2.00mm pitch, board edge mount), and environmental specifications (-55°C to 105°C, UL94 V-0). Physical and functional compatibility is complete.

Q: What is the significance of the "LF" designation in the part number?

A: The "LF" suffix indicates lead-free construction, reflecting RoHS compliance. The 88945-302LF is manufactured to RoHS standards, whereas the original 88945-302 is RoHS non-compliant.

Q: Are there packaging differences between these parts?

A: Yes. The 88945-302 is supplied in bulk packaging, while the 88945-302LF is supplied in tube packaging. Both packaging formats are suitable for automated assembly and manual handling.

Q: Why is the original 88945-302 listed as obsolete?

A: The 88945-302 has been superseded by the 88945-302LF. Amphenol ICC has transitioned production to the RoHS-compliant variant to align with current regulatory requirements and environmental standards.

Q: Are the electrical and thermal specifications identical?

A: Yes. Both parts are rated for 1A current, 1000V voltage, and operate across the same temperature range of -55°C to 105°C. Material flammability rating (UL94 V-0) is identical.

Q: What is the contact pitch, and why is it important for substitution?

A: The contact pitch is 0.079 inches (2.00mm). This dimension is critical for mechanical compatibility with mating connectors and PCB layouts. Both the 88945-302 and 88945-302LF share this specification.
