TE Connectivity 748470-1 D-Sub High Density Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 748470-1 is a D-Sub High Density plug housing designed for male contacts in 44-position configurations. This connector belongs to the AMPLIMITE HDP-22 series and features a 3-row shell layout with grounding indents and shielding. The part is classified as obsolete, making identification of active equivalent components necessary for ongoing procurement and system maintenance. Substitute parts must maintain identical electrical and mechanical specifications to ensure direct compatibility in existing applications.

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 748470-1 is determined by strict equivalence across the following critical parameters:

Electrical and Mechanical Compatibility Requirements:

• Connector Style: D-Sub, High Density
• Connector Type: Plug for Male Contacts
• Number of Positions: 44
• Number of Rows: 3
• Shell Size, Connector Layout: 3 (DB, B) High Density
• Contact Type: Signal
• Mounting Type: Free Hanging (In-Line)
• Flange Feature: Housing/Shell (Unthreaded)
• Features: Grounding Indents, Shielded
• Shell Material, Finish: Steel, Tin Plated
• Dielectric Material: Polyamide (PA), Nylon, Glass Filled
• Color: Black

The substitute part 1658677-1 maintains complete equivalence across all specified parameters. The primary distinction is product status: the substitute is active and RoHS compliant, whereas the original part is obsolete and RoHS non-compliant.

Engineering Selection Recommendations

Primary Substitute: TE Connectivity 1658677-1

The TE Connectivity 1658677-1 is the direct equivalent for the obsolete 748470-1. This substitute maintains complete electrical and mechanical compatibility across all specified parameters including connector style, position count, row configuration, shell size, contact type, mounting method, and material composition.

Compliance Advantages:

The substitute part 1658677-1 is classified as active product status with RoHS compliance, whereas the original 748470-1 is obsolete and RoHS non-compliant. For applications subject to regulatory requirements or long-term supply chain planning, the substitute provides compliance alignment and ongoing manufacturer support.

Specification Alignment:

Both parts are manufactured by TE Connectivity within the AMPLIMITE HDP-22 series. The substitute provides documented shell finish thickness of 200µin (5.08µm) and defined REACH status (REACH Unaffected), whereas the original part specifications for these parameters are not provided. These additional specifications do not alter functional compatibility but provide enhanced documentation for the substitute.

Inventory Availability:

The substitute part 1658677-1 is available in active inventory (1094 Pcs New Original In Stock) with bulk packaging, compared to the original part status as obsolete.

Frequently Asked Questions (FAQ)

Q: Can the 1658677-1 directly replace the 748470-1 in existing applications?

A: Yes. The 1658677-1 maintains complete equivalence across all electrical and mechanical parameters specified for the 748470-1, including connector style, position count, row configuration, shell size, contact type, mounting method, flange feature, shielding, and material composition. Direct substitution is supported.

Q: What is the difference between these two part numbers?

A: The primary differences are product status and regulatory compliance. The 748470-1 is obsolete and RoHS non-compliant, while the 1658677-1 is active and RoHS compliant. The substitute also provides documented shell finish thickness (200µin / 5.08µm) and defined REACH status. All functional and mechanical specifications are identical.

Q: Are there any compatibility concerns with the packaging difference?

A: The original part 748470-1 packaging is not specified in the documentation. The substitute 1658677-1 is supplied in bulk packaging. Packaging format does not affect connector functionality or mechanical compatibility. Packaging selection is determined by procurement and inventory management requirements.

Q: Does the RoHS compliance difference affect electrical performance?

A: No. RoHS compliance status reflects regulatory material composition requirements and does not alter electrical performance or mechanical function. Both parts use identical shell material (steel, tin plated) and dielectric material (polyamide/nylon, glass filled). The compliance difference is relevant for regulatory adherence and supply chain requirements.

Q: Are both parts suitable for the same operating environments?

A: Both parts share identical moisture sensitivity level (MSL 1 - Unlimited), indicating equivalent environmental handling requirements. Operating temperature specifications are not provided for either part in the available documentation. Both parts feature grounding indents and shielding for signal integrity in equivalent applications.

Q: What is the significance of the shell finish thickness specification?

A: The substitute part 1658677-1 specifies shell finish thickness of 200µin (5.08µm). This specification is not provided for the original 748470-1. Shell finish thickness affects corrosion resistance and durability. The documented specification for the substitute provides enhanced material specification clarity without altering functional compatibility.

Q: Can I use the 748470-1 if the 1658677-1 is unavailable?

A: The 748470-1 is classified as obsolete product. While the part may be available through inventory channels, procurement of active products is recommended for new designs and long-term applications. The 1658677-1 provides equivalent functionality with active product status and ongoing manufacturer support.
