Key Parameters

Substitute Part Grouping Explanation

The substitute part TE Connectivity AMP Connectors 5646534-1 qualifies as a direct equivalent based on the following critical parameters that determine substitutability:

Matching Parameters:

• Number of Positions: 154 (110 + 44 Ground) — identical configuration
• Pitch: 0.079" (2.00mm) — identical spacing
• Connector Type: Header, Male Pins — identical pin configuration
• Mounting Type: Through Hole — identical mounting method
• Termination: Press-Fit — identical termination technology
• Connector Usage: Backplane — identical application category

Substitution Logic: The 5646534-1 maintains functional and mechanical compatibility with the original 123970 through identical position count, pitch spacing, pin type, and termination method. These parameters are the primary determinants of physical and electrical interchangeability in backplane connector applications. The substitute part is manufactured by TE Connectivity AMP Connectors and carries active product status with current inventory availability.

These parameters ensure direct functional replacement without design modification.

Packaging and Availability: The substitute is supplied in Tube packaging with active inventory status, providing immediate availability for component procurement and assembly operations.

Frequently Asked Questions (FAQ)

Q: Can the 5646534-1 be used as a direct replacement for the 123970 in existing designs?

A: Yes. The 5646534-1 maintains identical position count (154), pitch spacing (2.00mm), connector type (Header, Male Pins), mounting method (Through Hole), and termination technology (Press-Fit). These parameters determine physical and electrical compatibility in backplane applications. No design modification is required.

Q: What is the primary reason for substitution?

A: The original part 123970 is classified as obsolete and is no longer in active production. The 5646534-1 is an active product with current manufacturing and inventory support, ensuring continued component availability.

Q: Are there differences in electrical performance between the two parts?

A: The substitute 5646534-1 specifies electrical ratings (1.5 A current rating, 500Vrms voltage rating) and operating temperature range (-55°C ~ 125°C). The original part's electrical specifications are not provided in available documentation. The substitute's specifications represent the electrical performance envelope for this connector category.

Q: What packaging format is the substitute supplied in?

A: The 5646534-1 is supplied in Tube packaging, suitable for automated assembly and component handling operations.

Q: Does the substitute meet current regulatory requirements?

A: Yes. The 5646534-1 is RoHS Compliant and carries ECCN classification EAR99. Moisture Sensitivity Level is rated as 1 (Unlimited), indicating no special moisture control requirements during storage or handling.

Q: Are there any mechanical differences in connector style or row configuration?

A: The substitute 5646534-1 specifies connector style AB 22 with 5 + 2 row configuration. These details provide additional mechanical definition for the 154-position layout. The original part documentation does not specify these parameters, but the identical position count and pitch ensure mechanical compatibility.

Q: What is the contact finish specification?

A: The substitute 5646534-1 features gold contact finish with 30.0µin (0.76µm) thickness, providing corrosion resistance and reliable electrical contact performance in backplane applications.
