3M 2514-5002-UG Equivalent & Substitute Parts

Part Overview

The 3M 2514-5002-UG is a rectangular connector header designed for through-hole, right-angle board-to-board or cable applications. This 14-position connector operates at 0.100" (2.54mm) pitch with shrouded 4-wall construction and push-pull fastening. The part is classified as obsolete, making identification of equivalent and substitute components necessary for ongoing design support and procurement continuity.

Substitute Part Grouping Explanation

Substitution eligibility for the 3M 2514-5002-UG is determined by the following critical parameters:

Connector type (Header)
Contact type (Male Pin)
Pitch - mating (0.100" / 2.54mm)
Number of positions (14)
Number of rows (2)
Row spacing - mating (0.100" / 2.54mm)
Mounting type (Through Hole, Right Angle)
Shrouding configuration (Shrouded - 4 Wall)
Fastening type (Push-Pull)
Termination method (Solder)

The substitute parts identified—Amphenol ICC (FCI) 69155-014 and 69155-314LF—meet all critical dimensional and functional parameters. Both are active-status rectangular connectors with identical pitch, position count, row configuration, mounting orientation, and fastening mechanism. Variations in contact geometry, contact finish specifications, and current rating are secondary parameters that do not prevent functional substitution in applications designed for the original part.

Engineering Selection Recommendations

Both Amphenol ICC (FCI) substitute parts are active-status components suitable for replacing the obsolete 3M 2514-5002-UG in new designs and production continuity scenarios.

Amphenol ICC 69155-314LF is the preferred substitute for applications requiring RoHS compliance. This part carries RoHS Compliant certification and maintains all critical dimensional and functional parameters of the original connector. The enhanced contact finish thickness (30.0µin vs. 15.0µm) and GXT™ mating surface treatment provide improved contact durability.

Amphenol ICC 69155-014 serves as an alternative substitute for applications where RoHS compliance is not required. This part is functionally equivalent in all critical parameters and is available in active production status.

Both substitutes operate within the same temperature range (-55°C ~ 105°C) and maintain UL94 V-0 flammability certification. The current rating reduction from 1.75A to 1A in both substitutes must be evaluated against application requirements. Contact geometry differences (square vs. circular) do not affect mating compatibility with standard 0.100" pitch receptacles.

Frequently Asked Questions (FAQ)

Q: Can Amphenol ICC 69155-014 and 69155-314LF be used interchangeably with the 3M 2514-5002-UG?

A: Both Amphenol ICC parts meet all critical substitution parameters: 14-position, 2-row, 0.100" pitch, through-hole right-angle header with shrouded 4-wall construction and push-pull fastening. They are functionally equivalent for board-to-board and cable applications. The primary difference is RoHS compliance status; 69155-314LF is RoHS Compliant while 69155-014 is not.

Q: What is the significance of the current rating difference (1.75A vs. 1A)?

A: The original 3M part is rated for 1.75A per contact, while both Amphenol ICC substitutes are rated for 1A per contact. Applications requiring current levels between 1A and 1.75A must be re-evaluated for the substitute parts. Applications operating at or below 1A per contact are unaffected.

Q: Are there packaging differences between these parts?

A: The 3M 2514-5002-UG is listed with unspecified packaging, while both Amphenol ICC substitutes are supplied in Bulk packaging. Confirm bulk packaging compatibility with your procurement and assembly processes.

Q: How do contact geometry differences affect compatibility?

A: The 3M part features square contact geometry while both Amphenol ICC substitutes use circular contacts. Both geometries are standard for 0.100" pitch rectangular connectors and mate with standard receptacles. Contact geometry does not affect mating compatibility.

Q: Which substitute should be selected for new designs?

A: For new designs subject to RoHS requirements, select Amphenol ICC 69155-314LF. For applications without RoHS mandates, either substitute is acceptable. Verify current rating requirements (1A maximum) against application specifications before final selection.
