3M 150260-2020-TH Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The 3M 150260-2020-TH is a 60-position receptacle connector with 0.079" (2.00mm) pitch, designed for surface mount board-to-board or cable applications. This connector features gold-plated mating contacts, push-pull fastening, and operates across -55°C to 105°C. The part is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications requiring this connector footprint and electrical specification.

Substitute Part Grouping Explanation

The 3M 150260-2020-RB qualifies as a direct substitute based on identical electrical and mechanical parameters: 60-position receptacle configuration, 0.079" (2.00mm) mating pitch, 2-row layout, surface mount termination, 1A current rating, 500VDC voltage rating, and -55°C to 105°C operating temperature range. Both connectors share the same base product number (150260), connector series (1502), contact geometry (square copper alloy), insulation material (thermoplastic UL94 V-0), and fastening mechanism (push-pull).

Substitution is valid based on these matching parameters:

Connector type and position count
Mating pitch and row configuration
Mounting and termination method
Electrical ratings (current and voltage)
Temperature operating range
Contact material and shape
Insulation specifications

Engineering Selection Recommendations

The 150260-2020-RB is the active production equivalent for the obsolete 150260-2020-TH. Both parts maintain identical mechanical and electrical compatibility for board-to-board and cable connector applications.

The primary distinction is regulatory compliance: the 150260-2020-RB is RoHS compliant, while the 150260-2020-TH is RoHS non-compliant. For new designs or applications subject to RoHS requirements, the 150260-2020-RB is the appropriate selection. The substitute also features increased gold plating thickness on mating contacts (30.0µin versus 15.0µin), providing enhanced contact durability and corrosion resistance.

Post-contact finish differs between the two parts: the main part uses tin-lead plating while the substitute uses tin plating. Both maintain identical post-contact thickness (200.0µin). This difference reflects the RoHS transition in the product line.

Frequently Asked Questions (FAQ)

Q: Can 150260-2020-RB directly replace 150260-2020-TH in existing assemblies?

A: Yes. Both connectors share identical mechanical dimensions, mating pitch (0.079"), position count (60), row configuration (2 rows), mounting type (surface mount), and electrical ratings (1A, 500VDC). PCB footprints and mating interfaces are interchangeable.

Q: What is the significance of the different contact finish thicknesses?

A: The 150260-2020-RB provides 30.0µin gold plating on mating contacts compared to 15.0µin on the 150260-2020-TH. Thicker plating extends contact life and improves resistance to wear and corrosion in high-cycle mating applications.

Q: Why does the substitute have different post-contact plating?

A: The transition from tin-lead to tin plating reflects RoHS compliance requirements. Both finishes maintain the same post-contact thickness (200.0µin) and provide equivalent solder joint reliability.

Q: Are there packaging differences between these parts?

A: The 150260-2020-TH packaging is not specified in available data. The 150260-2020-RB is supplied in bulk packaging. Confirm packaging requirements with your procurement specification.

Q: Which part should be selected for new production?

A: The 150260-2020-RB is the active production part and is recommended for all new designs. It provides RoHS compliance, improved contact durability, and ongoing manufacturer support.

Q: Are both parts suitable for the full -55°C to 105°C temperature range?

A: Yes. Both connectors are rated for identical operating temperature ranges and material flammability specifications (UL94 V-0).
