Key Parameters

Substitute Part Grouping Explanation

Substitution of the 748642-1 is based on strict equivalence across all critical electrical and mechanical parameters. The substitute part 5748642-1 maintains identical specifications for connector style, position count, row configuration, shell size layout, contact type, mounting method, and flange design. Both components are receptacles for female contacts within the AMPLIMITE HDP-22 series with 62-position, 3-row, high-density D-Sub architecture.

The substitution is valid based on the following matching parameters:

• Connector Style: D-Sub, High Density
• Connector Type: Receptacle for Female Contacts
• Number of Positions: 62
• Number of Rows: 3
• Shell Size, Connector Layout: 4 (DC, C) High Density
• Contact Type: Signal
• Mounting Type: Free Hanging (In-Line)
• Flange Feature: Cable Side (4-40)
• Shell Material, Finish: Steel, Tin Plated
• Color: Black
• Series: AMPLIMITE HDP-22

Parameter Comparison

Engineering Selection Recommendations

The 5748642-1 is the direct active equivalent for the obsolete 748642-1. Selection of the substitute part is based on the following engineering criteria:

Product Status: The 748642-1 is classified as obsolete, while the 5748642-1 maintains active product status. Active status ensures continued manufacturer support, availability, and compliance with current standards.

Compliance Certifications: The 5748642-1 is RoHS compliant, whereas the 748642-1 is RoHS non-compliant. For applications subject to RoHS regulations or requiring compliance with environmental directives, the 5748642-1 is the appropriate selection.

Functional Equivalence: Both parts maintain identical electrical and mechanical specifications across all critical parameters including connector style, position count, row configuration, shell size, mounting type, and flange design. The substitute part includes grounding indents as an additional feature and specifies thermoplastic dielectric material compared to the polyamide nylon glass-filled material of the original part.

Availability: The 5748642-1 demonstrates higher current inventory levels (1059 pcs) compared to the 748642-1 (823 pcs), supporting procurement reliability for new designs and system replacements.

Frequently Asked Questions (FAQ)

Q: Can the 5748642-1 directly replace the 748642-1 in existing applications?

A: Yes. The 5748642-1 maintains identical specifications for all critical connector parameters including position count (62), row configuration (3), shell size layout (4 DC, C High Density), mounting type (Free Hanging In-Line), and flange design (Cable Side 4-40). Both are receptacles for female contacts within the AMPLIMITE HDP-22 series.

Q: What are the differences between the 748642-1 and 5748642-1?

A: The primary differences are product status, RoHS compliance, and dielectric material specification. The 5748642-1 is active (versus obsolete), RoHS compliant (versus non-compliant), includes grounding indents as an additional feature, specifies thermoplastic dielectric material, and provides documented shell finish thickness of 200µin (5.08µm).

Q: Are there packaging differences between these parts?

A: The 748642-1 packaging is not specified in available documentation. The 5748642-1 is supplied in bulk packaging. Confirm packaging requirements with procurement specifications for your application.

Q: Do both parts require separate contact components?

A: Yes. Both the 748642-1 and 5748642-1 are housings only. Contacts are not included and must be procured separately according to your application requirements.

Q: What is the significance of the grounding indents feature on the 5748642-1?

A: Grounding indents on the 5748642-1 provide enhanced shielding and grounding capability compared to the 748642-1. This feature improves electromagnetic compatibility performance in high-density signal applications.

Q: Are both parts suitable for the same environmental conditions?

A: Both parts share identical Moisture Sensitivity Level (MSL) classification of 1 (Unlimited), indicating equivalent moisture handling characteristics. Operating temperature, ingress protection, and mating cycle specifications are not provided for either part in available documentation.

Q: Which part should be selected for new designs?

A: The 5748642-1 is the appropriate selection for new designs based on active product status, RoHS compliance, and enhanced feature set including grounding indents.
