TE Connectivity 102618-7 Rectangular Connector Header: Equivalent & Substitute Parts

Part Overview

The TE Connectivity 102618-7 is a shrouded rectangular connector header designed for through-hole mounting in board-to-board or cable applications. This component features 18 positions arranged in 2 rows with 0.100" (2.54mm) pitch spacing and is part of the AMPMODU Mod II series. The connector utilizes male pins with gold-plated mating contacts and tin-lead plated posts for solder termination.

The 102618-7 carries an obsolete product status. Locating equivalent substitute parts is necessary to support legacy system maintenance, repair operations, and ongoing production requirements where original inventory becomes depleted or unavailable.

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 102618-7 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications in the following categories:

Electrical Parameters:

• Contact type (Male Pin)
• Number of positions (18)
• Number of rows (2)
• Mating pitch (0.100" / 2.54mm)
• Row spacing (0.100" / 2.54mm)
• Current rating (3A)
• Operating temperature range (-65°C ~ 105°C)
• Contact material (Phosphor Bronze)

Mechanical Parameters:

• Connector type (Header)
• Shrouding configuration (Shrouded - 4 Wall)
• Mounting type (Through Hole)
• Termination method (Solder)
• Contact length specifications (Mating: 0.318", Post: 0.125", Overall: 0.533")
• Insulation height (0.440")
• Contact shape (Square)
• Fastening type (Detent Lock)
• Insulation material (Thermoplastic)
• Flammability rating (UL94 V-0)

Acceptable Variations:

• Product status (Obsolete to Active)
• Packaging format (bulk to tray)
• Contact finish on posts (Tin-Lead to Tin)
• RoHS compliance status
• REACH classification

The substitute part 5-102618-7 meets all substitution criteria and maintains full electrical and mechanical compatibility with the original 102618-7 component.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 5-102618-7 serves as a direct functional equivalent to the obsolete 102618-7 model. Both components share identical electrical and mechanical specifications across all critical parameters including connector geometry, contact configuration, pitch spacing, and thermal operating range.

The primary distinction between these parts is product lifecycle status. The 102618-7 is classified as obsolete, while the 5-102618-7 maintains active production status. This transition ensures continued component availability and supply chain reliability for applications requiring this connector type.

The 5-102618-7 incorporates RoHS compliance, whereas the original 102618-7 does not. This compliance improvement reflects current environmental and regulatory standards without altering the component's functional performance or physical characteristics.

The contact finish on the post differs between the two parts: the original uses Tin-Lead plating while the substitute uses Tin plating. Both finishes maintain equivalent electrical and mechanical properties for solder termination applications and are functionally interchangeable in circuit board assembly processes.

Packaging format differs between the parts (bulk versus tray), which affects handling and inventory management but does not impact electrical or mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can the 5-102618-7 be used as a direct replacement for the 102618-7 in existing designs?

A: Yes. The 5-102618-7 maintains identical electrical and mechanical specifications across all critical parameters. Pin configuration, pitch spacing, contact geometry, current rating, and operating temperature range are equivalent. The component functions identically in board-to-board and cable applications.

Q: What is the difference between Tin-Lead and Tin contact finishes on the post?

A: Both finishes provide equivalent electrical conductivity and solder wettability for through-hole termination. Tin plating (used on the 5-102618-7) represents a lead-free alternative to Tin-Lead plating (used on the 102618-7). Both are suitable for standard PCB assembly processes.

Q: Does the RoHS compliance difference affect component performance?

A: No. RoHS compliance status reflects manufacturing process standards and material composition restrictions, not functional performance. The 5-102618-7 achieves RoHS compliance while maintaining identical electrical and mechanical characteristics to the non-compliant 102618-7.

Q: Are there any compatibility issues with PCB footprints designed for the 102618-7?

A: No. The 5-102618-7 shares identical mechanical dimensions, pin spacing, and mounting hole configuration with the 102618-7. Existing PCB designs require no modification for component substitution.

Q: What is the significance of the packaging difference between bulk and tray formats?

A: Packaging format affects component handling, storage, and inventory management but does not influence electrical or mechanical performance. Both formats contain identical components suitable for the same applications.

Q: Why is the original 102618-7 classified as obsolete?

A: Obsolete status indicates the component has been discontinued from active production. The 5-102618-7 represents the current production equivalent, ensuring ongoing availability and supply chain continuity for applications requiring this connector type.

Q: Are the shrouding and detent lock features identical between both parts?

A: Yes. Both the 102618-7 and 5-102618-7 feature identical 4-wall shrouding and detent lock fastening mechanisms. These features ensure proper connector alignment and secure mating in board-to-board applications.

Q: What is the current rating for both connector models?

A: Both the 102618-7 and 5-102618-7 are rated for 3A continuous current per contact. This rating applies across the full operating temperature range of -65°C to 105°C.
