Substitute Part Grouping Explanation

Substitution of the TE Connectivity AMP 2-84953-3 with the Samtec Inc. ZF1-23-01-TM-WT is based on the following alignment of critical electrical and mechanical parameters:

Matching Parameters:

• Number of Positions: 23 (identical contact count)
• Pitch: 0.039" (1.00mm) (identical spacing for PCB layout compatibility)
• Mounting Type: Surface Mount, Right Angle (identical board integration method)
• Termination: Solder (identical permanent connection method)
• Contact Material: Phosphor Bronze with Tin Finish (identical electrical properties)
• FFC/FCB Thickness: 0.30mm (identical cable compatibility)
• Locking Feature: Slide Lock (identical mechanical retention)
• Features: Zero Insertion Force (ZIF), Solder Retention (identical operational characteristics)
• Connector Category: FPC/FFC (flat flexible connector family)
• Product Status: Active (both parts in current production)
• RoHS Compliance: Both parts meet environmental standards

Differing Parameters:

• Connector/Contact Type: Main part uses Top contacts; substitute uses Bottom contacts (affects PCB side of connection)
• Height Above Board: Main part 0.101" (2.56mm); substitute 3.00mm (affects board clearance requirements)
• Housing Material: Main part uses LCP Glass Filled; substitute uses LCP only (minor material variation)
• Actuator Material: Main part uses PA Nylon Glass Filled; substitute uses PPS (different polymer, same functional class)
• Operating Temperature: Main part -40°C ~ 85°C; substitute -55°C ~ 105°C (substitute offers extended range)
• Voltage Rating: Main part 200V; substitute not specified (main part specification applies)
• Current Rating: Main part 1A; substitute not specified (main part specification applies)
• Material Flammability: Main part UL94 V-0; substitute UL94 V-2 (main part has superior rating)
• Packaging: Main part Tape & Reel; substitute Tube (different supply format)

Substitution is valid when PCB layout accommodates bottom-side connector mounting, board clearance permits 3.00mm height, and the extended operating temperature range of the substitute is acceptable or beneficial. The difference in contact position (top vs. bottom) represents the primary design consideration for substitution feasibility.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection Criteria:

The TE Connectivity AMP 2-84953-3 remains the specified part for applications requiring top-side connector mounting, UL94 V-0 flammability compliance, and operating temperatures within -40°C to 85°C. This part is active in production with established supply availability.

Substitute Selection Criteria:

The Samtec Inc. ZF1-23-01-TM-WT is a valid substitute when the following conditions are met:

1. PCB Layout Compatibility: The application design accommodates bottom-side connector mounting instead of top-side mounting. This represents the primary design change required for substitution.

2. Board Clearance: The PCB layout provides minimum 3.00mm clearance above the board surface. The substitute connector is 0.44mm taller than the main part (3.00mm vs. 2.56mm).

3. Temperature Requirements: The application operates within -55°C to 105°C, or the extended temperature range of the substitute is beneficial for the application.

4. Flammability Compliance: The application accepts UL94 V-2 material flammability rating. If UL94 V-0 is a mandatory requirement, the main part must be used.

5. Supply Chain Continuity: The substitute is selected when TE Connectivity AMP 2-84953-3 availability is constrained and design modifications to accommodate bottom-side mounting are feasible.

Compliance Status:

Both parts are RoHS compliant (main part RoHS Compliant; substitute ROHS3 Compliant), active in production, and suitable for current electronic assembly standards. Both parts feature identical electrical contact properties (Phosphor Bronze with Tin finish), identical pitch (1.00mm), identical position count (23), and identical ZIF/Slide Lock operational characteristics.

Frequently Asked Questions (FAQ)

Q: Can the Samtec ZF1-23-01-TM-WT be used as a direct drop-in replacement for the TE Connectivity AMP 2-84953-3?

A: No. The primary difference is connector/contact position: the main part uses top-side contacts while the substitute uses bottom-side contacts. This requires PCB layout modification. Additionally, the substitute is 0.44mm taller (3.00mm vs. 2.56mm), requiring verification of board clearance. Direct substitution without PCB redesign is not possible.

Q: Are the electrical specifications identical between these two connectors?

A: The electrical specifications are functionally equivalent for the parameters provided. Both connectors feature 23 positions at 1.00mm pitch, Phosphor Bronze contacts with Tin finish, 1A current rating per contact, and 200V voltage rating. The substitute's voltage and current ratings are not specified in available documentation; the main part specifications apply as the reference standard.

Q: What is the significance of the contact position difference (top vs. bottom)?

A: Contact position determines which side of the PCB the connector mounts to and interfaces with the flat flexible cable. Top-side contacts mount on the component side of the PCB; bottom-side contacts mount on the solder side. This is a fundamental design parameter that affects PCB layout, assembly sequence, and cable routing. Substitution requires PCB redesign to accommodate the alternate mounting side.

Q: Does the height difference affect compatibility?

A: Yes. The Samtec substitute is 0.44mm taller (3.00mm vs. 2.56mm above the board). Applications with limited vertical clearance, such as those with stacked PCBs or confined enclosures, must verify that the additional height does not violate mechanical constraints. This is a critical design consideration for substitution feasibility.

Q: Are the packaging formats interchangeable?

A: No. The main part is supplied in Tape & Reel (TR) format; the substitute is supplied in Tube format. These represent different supply and handling methods. Tape & Reel is typically used for automated assembly; Tube format is used for manual handling or lower-volume applications. Procurement and assembly processes must accommodate the different packaging format.

Q: What is the difference between UL94 V-0 and UL94 V-2 flammability ratings?

A: UL94 V-0 represents superior flammability performance compared to UL94 V-2. The main part (V-0) meets more stringent flame-retardant requirements. Applications requiring UL94 V-0 certification must use the main part. Applications with UL94 V-2 acceptance can use the substitute.

Q: Can the extended operating temperature range of the substitute (-55°C to 105°C) be used in place of the main part's range (-40°C to 85°C)?

A: The substitute's extended temperature range is a superset of the main part's range. If the application operates within the main part's specified range (-40°C to 85°C), either part is acceptable from a temperature perspective. The substitute offers additional margin for applications requiring extended temperature operation.

Q: Are both parts RoHS compliant?

A: Yes. The main part is RoHS Compliant; the substitute is ROHS3 Compliant. Both meet environmental and regulatory standards for lead-free and hazardous substance restrictions. ROHS3 represents a more recent compliance standard; both designations indicate acceptable environmental compliance.

Q: What is the significance of the different actuator materials (PA Nylon Glass Filled vs. PPS)?

A: Both materials are suitable for zero insertion force (ZIF) connector operation. Polyamide (PA) Nylon with glass reinforcement and Polyphenylene Sulfide (PPS) are different polymer formulations with comparable mechanical and thermal properties for this application. The material difference does not affect functional compatibility; both provide adequate actuator performance for slide lock retention and ZIF operation.

Q: How do I determine if the Samtec substitute is suitable for my application?

A: Evaluate the following criteria: (1) PCB layout can accommodate bottom-side connector mounting; (2) board clearance provides minimum 3.00mm above the board surface; (3) operating temperature range is within -55°C to 105°C or the extended range is beneficial; (4) UL94 V-2 flammability rating is acceptable; (5) supply chain or design flexibility justifies the PCB modification required for bottom-side mounting. If all criteria are met, the substitute is suitable.

Q: What inventory considerations apply to these parts?

A: The main part (TE Connectivity AMP 2-84953-3) has 668 units in stock; the substitute (Samtec ZF1-23-01-TM-WT) has 881 units in stock. Both parts are in active production with established supply channels. Inventory selection should be based on design requirements and lead time considerations rather than availability alone, as both parts are readily available.
