• Row configuration (2 rows)
• Mating pitch (0.100" / 2.54mm)
• Row spacing (0.100" / 2.54mm)
• Mounting method (Through Hole)
• Fastening mechanism (Push-Pull)

Electrical Performance:

• Current rating (3A minimum)
• Operating temperature range (-65°C to 105°C)
• Contact material (Copper Alloy)
• Contact finish (Tin)

Regulatory & Environmental:

• Flammability rating (UL94 V-0)
• RoHS compliance status
• Moisture sensitivity level (MSL 1)

The substitute part 5-146254-5 maintains full equivalence across all critical parameters while offering the advantage of active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 5-146254-5 is the direct substitute for the obsolete 5-146266-5. Both connectors are manufactured by TE Connectivity within the AMPMODU Mod II series and maintain identical electrical, mechanical, and environmental specifications.

Product Status Advantage: The 5-146254-5 carries active product status, ensuring ongoing manufacturing support, consistent availability, and long-term supply chain reliability. The 5-146266-5 is obsolete and subject to inventory depletion.

Compliance Equivalence: Both parts meet UL94 V-0 flammability requirements and maintain RoHS compliance. The 5-146254-5 specifically carries ROHS3 certification, representing the current regulatory standard. Both parts are classified as MSL 1 (Unlimited moisture sensitivity), eliminating special storage or handling requirements.

Termination Compatibility: The primary difference between the two parts is termination specification. The 5-146266-5 features kinked pin termination with solder, while the 5-146254-5 specifies standard solder termination. Both termination methods are compatible with standard through-hole PCB assembly processes. The kinked pin design of the original part provides mechanical retention during assembly; the standard solder termination of the substitute achieves equivalent mechanical and electrical performance through solder joint formation alone.

Functional Equivalence: All critical parameters determining connector function and compatibility are identical: 10-position, 2-row configuration; 0.100" (2.54mm) pitch; 3A current rating; -65°C to 105°C operating range; push-pull fastening; and through-hole mounting. Direct substitution is supported without design modification.

Frequently Asked Questions (FAQ)

Q: Can the 5-146254-5 be used as a direct replacement for the 5-146266-5 in existing designs?

A: Yes. The 5-146254-5 is electrically and mechanically equivalent to the 5-146266-5 across all critical parameters. Both connectors share identical pitch spacing, position count, row configuration, current rating, temperature range, and contact specifications. Direct substitution is supported without PCB redesign or assembly process modification.

Q: What is the difference between kinked pin and standard solder termination?

A: The 5-146266-5 features kinked pin termination, which provides mechanical retention of the connector during PCB assembly by anchoring the pin in the through-hole. The 5-146254-5 uses standard solder termination, where the pin is retained solely through the solder joint. Both methods achieve equivalent mechanical strength and electrical performance in production assembly. Standard solder termination is the current manufacturing standard for this connector series.

Q: Are there any packaging differences between these parts?

A: The 5-146266-5 is listed with unspecified packaging, while the 5-146254-5 is supplied in bulk packaging. This difference affects order quantities and handling but does not impact connector form, fit, or function. Bulk packaging is standard for active production parts.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both the 5-146266-5 and 5-146254-5 are RoHS compliant. The 5-146254-5 carries ROHS3 certification, representing the current regulatory standard. Both parts meet UL94 V-0 flammability requirements and are classified as MSL 1, requiring no special moisture control during storage or handling.

Q: What is the current availability status of each part?

A: The 5-146266-5 is obsolete and subject to limited remaining inventory. The 5-146254-5 is an active product with ongoing manufacturing support and consistent availability. For new designs or production continuity, the 5-146254-5 is the recommended selection.

Q: Are the contact specifications identical between the two parts?

A: Yes. Both connectors feature copper alloy contacts with tin finish, 100.0µin (2.54µm) finish thickness on both mating and post surfaces, square contact shape, and 0.230" (5.84mm) mating contact length. Contact material, finish, and dimensional specifications are identical.

Q: Can these connectors be used interchangeably in board-to-board and cable applications?

A: Yes. Both the 5-146266-5 and 5-146254-5 are specified for board-to-board or cable style applications with push-pull fastening. The connector type, fastening mechanism, and mounting method are identical, supporting equivalent application flexibility.

Q: What is the operating temperature range for both connectors?

A: Both connectors operate across the identical temperature range of -65°C to 105°C. This extended range supports applications in industrial, automotive, and aerospace environments without thermal derating.

Q: Is the 3A current rating sufficient for my application?

A: The 3A current rating applies to both the 5-146266-5 and 5-146254-5. Verify that your application current requirements do not exceed this specification. Current capacity is determined by contact material, contact geometry, and termination method, all of which are identical between the two parts.
