3M 961234-5804-AR Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The 3M 961234-5804-AR is an active rectangular connector header designed for through-hole, right-angle board-to-board applications. This 34-position, 2-row connector operates across -25°C to 105°C and features gold-plated mating contacts with tin-plated posts. The part is RoHS compliant and carries UL94 V-0 flammability certification. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling component interchangeability in applications where the primary part is unavailable or inventory constraints exist.

Substitute Part Grouping Explanation

The Amphenol ICC (FCI) 68021-134HLF qualifies as a substitute for the 3M 961234-5804-AR based on alignment of critical electrical and mechanical parameters. Both connectors share identical mating pitch (0.100" / 2.54mm), row spacing (0.100" / 2.54mm), position count (34 positions across 2 rows), contact type (male pin), mounting configuration (through-hole, right-angle), termination method (solder), fastening mechanism (push-pull), contact shape (square), and insulation color (black). Both parts carry UL94 V-0 flammability certification, RoHS compliance, and MSL 1 rating. The substitute maintains board-to-board style connectivity with unshrouded design and gold mating contact finish. These aligned parameters establish functional and mechanical interchangeability for applications requiring 34-position, 2.54mm-pitch rectangular connectors.

Parameter Comparison

Engineering Selection Recommendations

Both the 3M 961234-5804-AR and Amphenol ICC 68021-134HLF are active products with RoHS compliance and UL94 V-0 certification, establishing equivalent compliance posture for regulated applications. The Amphenol ICC substitute provides extended operating temperature range (-65°C to 125°C versus -25°C to 105°C) and higher current rating per contact (3A versus 2A), offering performance headroom in thermal and current-demanding environments. Both connectors maintain identical mechanical and electrical interface specifications, supporting direct substitution in board-to-board applications requiring 34-position, 2.54mm-pitch connectivity. Selection between these parts should be based on application-specific thermal and current requirements, inventory availability, and supply chain considerations.

Frequently Asked Questions (FAQ)

Q: What determines compatibility between the 3M 961234-5804-AR and the Amphenol ICC 68021-134HLF?

A: Compatibility is established through alignment of critical parameters: 34-position count, 2-row configuration, 0.100" (2.54mm) mating pitch, 0.100" (2.54mm) row spacing, male pin contact type, through-hole right-angle mounting, solder termination, push-pull fastening, square contact shape, and gold mating contact finish. Both connectors are unshrouded, board-to-board style headers with identical electrical and mechanical interfaces.

Q: Are there differences in operating temperature ranges between these connectors?

A: Yes. The 3M 961234-5804-AR operates from -25°C to 105°C, while the Amphenol ICC 68021-134HLF operates from -65°C to 125°C. The Amphenol ICC part provides extended temperature capability and is suitable for applications requiring broader thermal performance.

Q: How do the current ratings compare?

A: The 3M 961234-5804-AR is rated at 2A, while the Amphenol ICC 68021-134HLF is rated at 3A per contact. The Amphenol ICC substitute supports higher current density and is appropriate for applications with elevated current requirements.

Q: Do both connectors meet the same compliance standards?

A: Yes. Both parts are RoHS compliant, carry UL94 V-0 flammability certification, and are classified as MSL 1 (Unlimited moisture sensitivity level). Both are assigned ECCN EAR99 export classification.

Q: What is the packaging difference between these parts?

A: The 3M 961234-5804-AR is supplied without specified packaging designation, while the Amphenol ICC 68021-134HLF is packaged in bags.

Q: Can the Amphenol ICC 68021-134HLF be used as a direct replacement in existing designs?

A: Yes, provided the application does not require the specific insulation material or contact material properties of the original 3M part. Both connectors share identical mating interfaces, mounting configurations, and electrical characteristics for standard board-to-board applications.
