TE Connectivity 1-281523-0 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 1-281523-0 is an AMP-Latch series rectangular connector header designed for through-hole, right-angle board-to-cable/wire applications. This shrouded, 10-position connector with 2.54mm pitch and male pin contacts operates with solder termination and latch lock/eject hook fastening. The part is currently active in production with 955 units in stock. Equivalent and substitute parts are identified to support design flexibility, supply chain continuity, and application-specific requirements where mechanical or electrical parameters align with the original specification.

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 1-281523-0 is determined by strict alignment of the following core parameters:

Critical Matching Parameters:

Pitch - Mating: 0.100" (2.54mm)
Number of Positions: 10
Number of Rows: 2
Row Spacing - Mating: 0.100" (2.54mm)
Connector Type: Header
Contact Type: Male Pin

Engineering Selection Recommendations

All substitute parts listed are active products with RoHS compliance and MSL 1 (Unlimited) moisture sensitivity ratings, matching the regulatory and environmental requirements of the TE Connectivity 1-281523-0.

Amphenol ICC (FCI) Quickie™ Series (71922-110LF, 71922-210LF): These parts provide direct functional equivalence with identical pitch, position count, and mounting configuration. The primary differences are contact shape (square vs. circular), contact material (phosphor bronze vs. copper alloy), and contact finish thickness. Both variants are available in high inventory quantities (1560 and 2376 units respectively) and carry REACH Affected status. The 71922-210LF variant includes short fastening hooks, while 71922-110LF uses standard latch lock/eject hooks.

3M D3000 and 3000 Series (D3793-5202-AR, N3793-5302RB, N3793-5203RB, N3793-5303RB): These parts provide full functional equivalence with specified operating temperature range (-55°C to 105°C) and current rating (1.75A). The D3793-5202-AR uses brass contact material with shorter post length (0.112"), while the N3793 variants use copper alloy with variable post lengths (0.112" or 0.155"). The N3793 series variants differ in fastening type (long vs. short hooks) and post length, accommodating different PCB stack-up requirements. All 3M parts carry REACH Unaffected or undefined status and are available in tray or bulk packaging.

Selection between substitute parts should be based on:

Required contact post length for PCB thickness compatibility
Fastening hook length (short vs. long) for mating connector clearance
Packaging format preference (tube, tray, or bulk)
Operating temperature and current rating requirements
Supply chain and inventory availability

Frequently Asked Questions (FAQ)

Q: Can I substitute the TE Connectivity 1-281523-0 with any of the listed parts?

A: Yes, all listed parts are functionally equivalent for applications requiring a 10-position, 2.54mm pitch, right-angle header with solder termination and 4-wall shrouding. The core mating interface, board footprint, and electrical characteristics are identical across all variants.

Q: What is the difference between the Amphenol 71922-110LF and 71922-210LF?

A: Both parts are electrically and mechanically identical. The primary difference is the fastening type: 71922-110LF uses standard latch lock/eject hooks, while 71922-210LF uses short latch lock/eject hooks. Selection depends on mating connector clearance requirements and PCB layout constraints.

Q: Why do the 3M N3793 parts have different post lengths?

A: The N3793 series offers two post length options: 0.112" (2.84mm) for standard PCB applications and 0.155" (3.94mm) for applications requiring deeper solder penetration or thicker PCB stacks. Both lengths maintain identical mating interface dimensions and are interchangeable from a connector perspective.

Q: Are there temperature or current rating differences between the TE and substitute parts?

A: The TE Connectivity 1-281523-0 does not specify operating temperature or current rating in the provided data. The 3M parts specify -55°C to 105°C operating temperature and 1.75A current rating. The Amphenol parts do not specify these parameters. For applications with defined thermal or current requirements, the 3M parts provide explicit ratings.

Q: What is the significance of contact finish thickness variations?

A: Contact finish thickness affects durability and wear resistance. The TE part specifies 8.00µin (0.203µm) mating finish, while substitutes range from 10.0µin to 30.0µin. Higher thickness provides greater protection against corrosion and contact wear in high-cycle mating applications. For standard applications, all thicknesses are acceptable.

Q: Do packaging differences affect part compatibility?

A: No. Packaging format (tube, tray, or bulk) affects handling, storage, and ordering logistics but does not affect electrical or mechanical compatibility. Selection should be based on manufacturing process requirements and inventory management practices.

Q: What does REACH status mean for part selection?

A: REACH status indicates compliance with European chemical regulations. TE Connectivity 1-281523-0 shows "Vendor Undefined" status. Amphenol parts are "REACH Affected," and 3M parts are "REACH Unaffected" or "Vendor Undefined." For applications requiring REACH compliance documentation, verify with the supplier or select parts with explicit REACH Unaffected status.

Q: Can I mix contact materials (copper alloy, phosphor bronze, brass) in the same application?

A: Yes. All contact materials specified are suitable for standard PCB header applications. Contact material differences do not affect mating compatibility. Selection can be based on availability, cost, or specific corrosion resistance requirements for the application environment.

Q: Are the circular and square contact shapes interchangeable?

A: Yes. The TE part uses circular contacts while most substitutes use square contacts. Both shapes provide equivalent electrical contact and mechanical retention in standard header applications. The shape difference does not affect mating performance or board footprint.
