TE Connectivity AMP Connectors 103233-7 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 103233-7 is a rectangular connector header designed for through-hole mounting applications. This vertical 16-position connector operates at 0.100" (2.54mm) pitch and supports board-to-board or cable interconnections. The connector features male pin contacts with gold-plated mating surfaces and tin-lead plated posts, rated for 3A current at operating temperatures between -55°C and 125°C. The product maintains active status in the AMPMODU Mod II series. Identification of equivalent substitute parts becomes necessary when addressing inventory constraints, lead time requirements, or specific application compatibility needs while maintaining electrical and mechanical performance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 103233-7 with the Amphenol ICC 10077239-116TLF is based on alignment of critical electrical and mechanical parameters. Both connectors share identical specifications for the following substitution-determining criteria:

• 16-position configuration with 2-row layout
• 0.100" (2.54mm) mating pitch and row spacing
• Male pin contact type with through-hole mounting
• Press-fit and solder termination capability
• Gold-plated mating contact surfaces
• 3A current rating
• UL94 V-0 flammability classification
• Unshrouded design with push-pull fastening
• Black insulation color
• Unlimited moisture sensitivity level (MSL 1)

Both parts function as board-to-board connectors with equivalent electrical performance within their respective operating temperature ranges. The substitute part is classified as a breakaway header variant within the BERGSTIK® II series, offering an alternative sourcing option while maintaining functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the TE Connectivity 103233-7 and Amphenol ICC 10077239-116TLF maintain active product status and share core electrical and mechanical compatibility across mating pitch, contact configuration, current rating, and flammability certification. The substitute part operates across an extended temperature range (-65°C to 130°C) compared to the original part (-55°C to 125°C), providing broader thermal performance capability.

A critical distinction exists in regulatory compliance: the Amphenol ICC 10077239-116TLF is RoHS compliant, while the TE Connectivity 103233-7 is RoHS non-compliant. Applications subject to RoHS requirements must utilize the substitute part. Conversely, applications with existing RoHS non-compliant specifications may continue with the original part.

Physical dimensional differences occur in contact post length (0.250" versus 0.190") and overall contact length (0.660" versus 0.608"), which may affect PCB design considerations and mating depth. The substitute part features phosphor bronze contact material with tin plating on posts, compared to copper alloy with tin-lead plating on the original. These material differences do not compromise electrical performance within the specified current and voltage parameters.

Packaging format differs between bulk (original) and tube (substitute), affecting inventory management and component handling procedures.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol ICC 10077239-116TLF directly replace the TE Connectivity 103233-7 in existing designs?

A: Direct replacement is possible for applications where the physical dimensions and material specifications are compatible with PCB layout and mating requirements. The contact post length difference (0.250" versus 0.190") must be evaluated against PCB thickness and connector receptacle specifications. Electrical performance remains equivalent for the specified 3A current rating.

Q: What is the significance of the RoHS compliance difference?

A: The Amphenol ICC 10077239-116TLF is RoHS compliant, while the TE Connectivity 103233-7 is RoHS non-compliant. Applications subject to RoHS directives or customer requirements must use the compliant substitute part. The compliance difference reflects the contact finish material composition, specifically the tin-lead versus tin plating on the post contacts.

Q: Are the operating temperature ranges interchangeable?

A: The Amphenol ICC 10077239-116TLF operates across -65°C to 130°C, exceeding the TE Connectivity 103233-7 range of -55°C to 125°C. The substitute part accommodates the original part's temperature requirements and extends capability to lower and higher extremes. Applications operating within the original temperature range function identically with either part.

Q: How do the contact material differences affect performance?

A: The TE Connectivity 103233-7 uses copper alloy contacts with tin-lead plating, while the Amphenol ICC 10077239-116TLF uses phosphor bronze contacts with tin plating. Both materials support the 3A current rating and gold-plated mating surfaces. Material selection reflects manufacturing process differences between manufacturers and does not impact electrical performance within specified parameters.

Q: What packaging considerations apply to substitution?

A: The original part ships in bulk packaging, while the substitute part uses tube packaging. This difference affects component handling, storage, and automated assembly processes. Tube packaging typically provides improved component protection during transport and storage compared to bulk packaging.

Q: Does the breakaway header designation on the substitute part affect compatibility?

A: The breakaway feature on the Amphenol ICC 10077239-116TLF indicates the connector can be separated into individual positions if required. This feature does not prevent standard 16-position operation and does not affect compatibility with standard receptacles designed for 16-position headers.

Q: Are there any dimensional constraints for PCB mounting?

A: The insulation height differs between parts (0.090" versus 0.100"), which may affect clearance calculations for components mounted adjacent to the connector. The contact post length difference (0.250" versus 0.190") impacts solder joint formation and PCB thickness compatibility. PCB design review is necessary when substituting between these parts.
