Key Parameters

Substitute Part Grouping Explanation

Substitution for the 88946-112 is based on maintaining identical electrical and mechanical parameters across the Metral® B series. The substitute part 88946-112LF meets all critical selection criteria:

Key Parameters for Substitution Compatibility:

• Connector type and socket configuration (Receptacle, Female Sockets)
• Position count and pitch (48 positions at 0.079" / 2.00mm)
• Mounting configuration (Board Edge, Through Hole, Right Angle)
• Termination method (Press-Fit)
• Electrical ratings (1A current, 1000V voltage)
• Operating temperature range (-55°C to 105°C)
• Contact finish specification (Gold, 30.0µin)
• Flammability rating (UL94 V-0)

The 88946-112LF variant differs only in packaging format (Tube) and compliance status, with no changes to form, fit, or function.

Parameter Comparison

Engineering Selection Recommendations

The 88946-112LF is the direct substitute for the obsolete 88946-112. Selection between these parts should be based on the following factors:

For New Designs and Long-Term Support: The 88946-112LF is the appropriate choice. It maintains identical electrical and mechanical specifications while offering active product status, ensuring continued availability and manufacturer support. The part is RoHS Compliant and REACH Affected, meeting current regulatory requirements for new component procurement.

For Legacy System Maintenance: The 88946-112 remains available in inventory (860 units) for applications requiring the original non-compliant variant. However, transition to the 88946-112LF is recommended where system design permits, as the original part is obsolete and future availability cannot be guaranteed.

Compliance Considerations: Organizations subject to RoHS or REACH regulations should specify the 88946-112LF. The original 88946-112 is RoHS non-compliant and REACH Unaffected, which may restrict its use in regulated markets or applications with compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can the 88946-112LF be used as a direct replacement for the 88946-112?

A: Yes. The 88946-112LF is electrically and mechanically identical to the 88946-112. Both parts share the same 48-position configuration, 2.00mm pitch, press-fit termination, gold contact finish, and electrical ratings (1A, 1000V). The only differences are product status (Active vs. Obsolete), compliance certifications, and packaging format (Tube).

Q: What is the difference between the packaging formats?

A: The 88946-112 uses standard packaging, while the 88946-112LF is supplied in Tube packaging. This difference does not affect connector performance or compatibility; it is a logistics and handling consideration only.

Q: Are there any form, fit, or function differences between these parts?

A: No. Both parts are from the Metral® B series and maintain identical dimensions, mounting configuration (Board Edge, Through Hole, Right Angle), and contact specifications. They are fully interchangeable at the board level.

Q: Why is the 88946-112 classified as obsolete?

A: The 88946-112 is obsolete due to its RoHS non-compliant status and REACH Unaffected classification. Amphenol ICC has transitioned to the 88946-112LF variant, which meets current regulatory requirements and is actively manufactured.

Q: Which part should be specified for new designs?

A: The 88946-112LF should be specified for all new designs. It is the active product with full manufacturer support, RoHS Compliance, and REACH Affected status, making it suitable for current and future applications.

Q: Is the 88946-112 still available for purchase?

A: Yes, 860 units of the 88946-112 are currently in stock as new original inventory. However, as an obsolete part, future availability is not guaranteed. The 88946-112LF, with 1884 units in stock, is the recommended long-term source.
