Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 88945-112 is determined by the following critical parameters:

• Connector Type & Position Count: Must be receptacle with female sockets in 24-position configuration
• Pitch & Mechanical Dimensions: Must maintain 0.079" (2.00mm) pitch with 4-row layout for board edge mounting compatibility
• Mounting & Termination: Must support board edge, through-hole, right-angle mounting with press-fit termination
• Electrical Ratings: Must meet or exceed 1A current and 1000V voltage specifications
• Contact Finish: Gold plating required for signal integrity
• Environmental Compliance: UL94 V-0 flammability rating required

The identified substitutes meet these core mechanical and electrical parameters while offering improvements in product status and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

88945-112LF (Primary Substitute)

The 88945-112LF is the direct form-fit-function equivalent manufactured by Amphenol ICC. This part maintains identical mechanical and electrical specifications while offering active product status and RoHS compliance. The LF designation indicates lead-free construction, aligning with modern manufacturing standards. This substitute is recommended for applications where Amphenol ICC platform continuity is required.

5536511-1 (Cross-Manufacturer Alternative)

The TE Connectivity 5536511-1 provides mechanical and mounting compatibility with identical pitch, position count, and board edge configuration. This part features an extended operating temperature range (-55°C to 125°C) compared to the original specification. However, the voltage rating of 30V is significantly lower than the 1000V specification of the original part. This substitute is suitable only for applications where the lower voltage rating is acceptable and cross-manufacturer sourcing is permissible.

Frequently Asked Questions (FAQ)

Q: Can 88945-112LF be used as a direct replacement for 88945-112?

A: Yes. The 88945-112LF maintains identical mechanical dimensions, pitch, position count, mounting configuration, and electrical ratings. The primary differences are product status (active vs. obsolete) and RoHS compliance. Both parts are from the Metral® B series and are functionally interchangeable.

Q: What is the significance of the "LF" designation in 88945-112LF?

A: The LF designation indicates lead-free construction, reflecting compliance with RoHS directives and modern environmental standards. The part is otherwise identical to the original specification.

Q: Is 5536511-1 compatible with applications designed for 88945-112?

A: Mechanical and mounting compatibility is confirmed. However, the 30V voltage rating of the 5536511-1 is substantially lower than the 1000V rating of the original part. This substitute is only suitable for applications where the lower voltage specification is acceptable. Verify voltage requirements before selection.

Q: What are the packaging differences between substitutes?

A: Both 88945-112LF and 5536511-1 are supplied in tube packaging. The original 88945-112 packaging specification is not provided in the technical data.

Q: Are there compliance differences between the three parts?

A: Yes. The 88945-112 is RoHS non-compliant. Both 88945-112LF and 5536511-1 are RoHS compliant. For applications subject to RoHS requirements, either substitute is appropriate. The 88945-112LF maintains Amphenol ICC sourcing, while 5536511-1 introduces TE Connectivity as an alternative supplier.
