3M 950514-6102-AR Equivalent & Substitute Parts

Part Overview

The 3M 950514-6102-AR is a 14-position rectangular receptacle connector with 0.079" (2.00mm) pitch, designed for through-hole board-to-board applications. This connector features gold-plated mating contacts and tin-plated posts, rated for 1A at 1000V, with an operating temperature range of -40°C to 105°C. The product is classified as obsolete, making identification of suitable substitute components essential for ongoing design support and procurement continuity.

Substitute Part Grouping Explanation

Substitution of the 3M 950514-6102-AR is determined by the following critical parameters that must remain constant:

Connector Type & Contact Configuration: Receptacle with female socket contacts
Position Count & Pitch: 14 positions at 0.079" (2.00mm) mating pitch
Mounting & Termination: Through-hole solder termination with push-pull fastening
Electrical Performance: Current and voltage ratings must meet or exceed the original specification
Physical Compatibility: Board-to-board style with compatible insulation height and contact length

The Samtec Inc. MMS-114-01-T-SV meets these substitution criteria while offering enhanced electrical performance and active product status.

Engineering Selection Recommendations

The Samtec MMS-114-01-T-SV is a direct functional substitute for the obsolete 3M 950514-6102-AR. Selection is supported by the following factors:

Electrical Performance: The substitute provides 3.9A per contact, exceeding the original 1A specification, with no voltage rating limitation specified, suitable for the 1000V application requirement.
Mechanical Compatibility: Identical pitch, position count, mounting type, and fastening mechanism ensure direct board-level compatibility.
Product Status: Active product status ensures long-term availability and supply chain continuity.
Regulatory Compliance: ROHS3 compliance and REACH unaffected status meet current environmental and regulatory requirements.
Temperature Range: Extended operating range (-55°C to 105°C) provides broader environmental performance than the original specification.

Physical dimensions show minimal variation (insulation height and contact length differences of 0.006" and 0.017" respectively), which are within typical PCB design tolerances for through-hole applications.

Frequently Asked Questions (FAQ)

Q: Can the Samtec MMS-114-01-T-SV directly replace the 3M 950514-6102-AR without PCB modification?

A: Yes. Both connectors share identical mating pitch (0.079"), position count (14), mounting type (through-hole), and fastening mechanism (push-pull). Minor dimensional variations in insulation height and contact post length are within standard PCB design tolerances and do not require board redesign.

Q: What are the key differences between these two connectors?

A: The primary differences are insulation material (thermoplastic versus liquid crystal polymer), contact material (copper alloy versus phosphor bronze), and electrical performance (1A versus 3.9A per contact). The substitute offers superior current-carrying capacity and extended temperature range.

Q: Is the Samtec part suitable for the same voltage application?

A: The original 3M connector is rated for 1000V. The Samtec substitute does not specify a voltage rating in the provided data. Voltage compatibility must be verified against the Samtec datasheet for the specific application requirement.

Q: What is the significance of the insulation material change?

A: Liquid crystal polymer (LCP) offers improved thermal and mechanical properties compared to thermoplastic. This material change supports the higher current rating and extended temperature range of the substitute connector.

Q: Are there any packaging or supply considerations?

A: The Samtec MMS-114-01-T-SV is supplied in tube packaging with 1148 units in stock, compared to the 3M part with 641 units available. The active product status ensures continued availability.
