Key Parameters

Substitute Part Grouping Explanation

Substitution for the 88946-302 is determined by strict equivalence across the following critical parameters:

• Connector Type & Configuration: Receptacle with female sockets, 48 positions arranged in 4 rows
• Electrical Specifications: 1A current rating, 1000V voltage rating, operating temperature range -55°C to 105°C
• Mechanical Interface: 0.079" (2.00mm) pitch, board edge mounting, through-hole, right-angle orientation
• Termination Method: Press-fit termination with board guide and spacer features
• Material & Safety: UL94 V-0 flammability rating, natural color

The substitute part 88946-302LF maintains identical electrical, mechanical, and functional specifications while offering improved compliance status and active production availability.

Parameter Comparison

Engineering Selection Recommendations

The 88946-302LF is the direct functional equivalent of the 88946-302 and is suitable for all applications requiring the Metral® B 48-position backplane connector specification.

Product Status Consideration: The 88946-302 is obsolete, while the 88946-302LF maintains active production status. For new designs and ongoing procurement, the 88946-302LF is the appropriate selection.

Compliance Advantage: The 88946-302LF is RoHS Compliant, whereas the original 88946-302 is RoHS non-compliant. This distinction is significant for applications subject to RoHS regulations or customer requirements mandating lead-free components.

Packaging: The 88946-302LF is supplied in tube packaging, compared to bulk packaging for the original part. Packaging selection should align with assembly process requirements and inventory management practices.

Frequently Asked Questions (FAQ)

Q: Are the 88946-302 and 88946-302LF electrically and mechanically interchangeable?

A: Yes. Both parts are identical in electrical specifications (1A, 1000V), mechanical configuration (48 positions, 0.079" pitch, board edge mounting), and functional features (press-fit termination, board guide, spacer). They are direct substitutes.

Q: What does the "LF" designation in 88946-302LF indicate?

A: The "LF" suffix indicates lead-free construction, reflecting RoHS compliance. The 88946-302LF meets RoHS requirements, whereas the original 88946-302 does not.

Q: Why is the 88946-302 listed as obsolete?

A: The 88946-302 has been discontinued by the manufacturer. The 88946-302LF represents the active production equivalent and should be used for all new procurement and design activities.

Q: Does the change from bulk to tube packaging affect connector performance?

A: No. Packaging format does not affect electrical or mechanical performance. Packaging selection should be based on assembly process compatibility and inventory management requirements.

Q: Can the 88946-302LF be used as a direct replacement in existing designs using the 88946-302?

A: Yes. The 88946-302LF is a direct functional replacement. All electrical, mechanical, and environmental specifications are identical. The RoHS compliance of the 88946-302LF may provide additional regulatory benefits for updated designs.
