TE Connectivity 104693-1 Rectangular Connector Header SMD 10 Position 1.27mm Equivalent & Substitute Parts

Part Overview

The TE Connectivity 104693-1 is a surface mount rectangular connector header designed for board-to-board applications. This component features 10 positions arranged in 2 rows with 0.050" (1.27mm) pitch spacing, shrouded 4-wall construction, and push-pull fastening. The connector is manufactured from phosphor bronze with gold-plated mating contacts and tin-lead plated posts, housed in liquid crystal polymer insulation rated UL94 V-0. The part is currently active in production with 692 units in stock.

Substitute parts are identified when electrical and mechanical parameters remain identical across connector pitch, position count, row configuration, contact material, insulation properties, operating temperature range, and mounting methodology. Equivalent components allow direct replacement in applications where the original part number becomes unavailable or when alternative sourcing is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of rectangular connector headers is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Pitch spacing (0.050"), contact material (phosphor bronze), current rating (0.5A per contact), and operating temperature range (-65°C to 105°C) must remain constant.

Mechanical Parameters: Position count (10), row configuration (2 rows), row spacing (0.050"), contact type (male pin), shrouding style (4-wall), mounting method (surface mount), and fastening mechanism (push-pull) must be identical.

Material Parameters: Insulation material (liquid crystal polymer), insulation color (black), and flammability rating (UL94 V-0) must match.

Contact Specifications: Mating contact length (0.120"), contact shape (circular), mating contact finish (gold at 30.0µin thickness), and post contact finish thickness (150.0µin) must be equivalent.

The substitute part 5-104693-1 meets all these criteria with one documented variance in post contact finish material (tin versus tin-lead) and regulatory compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both the 104693-1 and 5-104693-1 are active production components from TE Connectivity AMP Connectors within the AMPMODU 50/50 Grid series. The parts are electrically and mechanically equivalent across all critical connector specifications including pitch, position count, contact material, current rating, and operating temperature range.

The primary differences between these parts are regulatory and compliance-related:

104693-1 carries REACH Affected status with tin-lead post plating and not applicable RoHS designation, suitable for applications where legacy compliance requirements are specified.

5-104693-1 is ROHS3 Compliant with REACH Unaffected status and tin post plating, appropriate for applications requiring modern regulatory compliance. This variant is currently in higher inventory (1474 units versus 692 units).

Selection between these parts depends on application-specific regulatory requirements and compliance documentation needs. Both parts maintain identical electrical performance, mechanical fit, and thermal operating characteristics. The post contact finish variance (tin-lead versus tin) does not affect electrical or mechanical compatibility in board-to-board mating applications.

Frequently Asked Questions (FAQ)

Q: Are the 104693-1 and 5-104693-1 directly interchangeable in PCB assembly?

A: Yes. Both parts are mechanically and electrically identical in all critical parameters including pitch spacing (0.050"), position count (10), row configuration (2 rows), contact material (phosphor bronze), current rating (0.5A per contact), and operating temperature range (-65°C to 105°C). The parts are directly substitutable in board-to-board connector applications.

Q: What is the difference between tin-lead and tin post plating?

A: The 104693-1 features tin-lead post plating while the 5-104693-1 uses tin post plating. Both finishes provide equivalent electrical conductivity and solder joint reliability. The tin finish in the 5-104693-1 reflects compliance with modern lead-free manufacturing standards (ROHS3 Compliant).

Q: Which part should be selected for new designs?

A: The 5-104693-1 is recommended for new designs due to ROHS3 compliance and REACH Unaffected status, which align with current regulatory requirements. This part also maintains higher inventory availability (1474 units in stock).

Q: Are there any mechanical differences between these connectors?

A: No. Both parts share identical mechanical specifications including shrouded 4-wall construction, push-pull fastening, surface mount configuration, board lock features, mating contact length (0.120"), insulation height (0.367"), and mated stacking height (9.91mm).

Q: What applications are these connectors suitable for?

A: Both parts are rated for automotive, general purpose, medical, military, and telecommunications applications. The UL94 V-0 flammability rating and -65°C to 105°C operating temperature range support these diverse application categories.

Q: Is the 0.050" (1.27mm) pitch compatible with standard PCB design tools?

A: Yes. The 0.050" pitch is a standard spacing in rectangular connector design and is supported by all major PCB design software packages. The 2-row configuration with 0.050" row spacing is part of the AMPMODU 50/50 Grid standard.

Q: What is the current handling capacity per contact?

A: Both connectors are rated for 0.5A per contact. With 10 total positions, the connector supports a maximum continuous current of 5.0A when all contacts are fully loaded.

Q: Are these connectors suitable for high-temperature applications?

A: Yes. Both parts operate across the temperature range of -65°C to 105°C. The liquid crystal polymer insulation material and phosphor bronze contact material maintain electrical and mechanical properties throughout this range.
