3M 8564-4500PL 64-Position Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The 3M 8564-4500PL is a 64-position receptacle connector with 0.100" (2.54mm) pitch, designed for through-hole PCB mounting with gold-plated contacts. This connector operates across -55°C to 105°C and is rated for 1A at 1000V. The product is currently obsolete, making identification of compatible substitute parts essential for legacy system maintenance and board redesigns.

Substitute Part Grouping Explanation

Substitution eligibility for the 3M 8564-4500PL is determined by strict alignment of the following core parameters:

Connector Type & Contact Configuration: Must be a receptacle with female socket contacts
Position Count & Arrangement: Must accommodate 64 positions in a 2-row configuration
Pitch Specifications: Mating pitch and row spacing must both be 0.100" (2.54mm)
Mounting & Termination: Must support through-hole PCB mounting
Contact Interface: Must feature gold-plated mating surfaces for electrical compatibility
Fastening Mechanism: Must utilize push-pull fastening
Flammability Compliance: Must meet UL94 V-0 rating

The TE Connectivity AMP Connectors 8-534206-2 satisfies all mandatory substitution criteria listed above.

Engineering Selection Recommendations

The TE Connectivity AMP Connectors 8-534206-2 is a direct functional substitute for the obsolete 3M 8564-4500PL. Both connectors share identical mechanical and electrical interface specifications across all critical parameters: 64-position configuration, 0.100" pitch, through-hole mounting, push-pull fastening, and UL94 V-0 flammability rating.

The substitute part offers operational advantages: an extended temperature range (-65°C to 125°C versus -55°C to 105°C) and higher current capacity (2A versus 1A). The substitute is actively manufactured and RoHS compliant, supporting long-term supply chain continuity and regulatory compliance for new designs or board revisions.

Physical dimensions differ slightly: the substitute features a reduced insulation height (0.320" versus 0.425") and increased contact post length (0.115" versus 0.110"). These dimensional variations require PCB layout verification to confirm mechanical clearance and solder joint accessibility during assembly.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 8-534206-2 directly replace the 3M 8564-4500PL in existing designs?

A: Electrical and functional compatibility is confirmed across all mating interface specifications. Physical layout verification is required due to differences in insulation height and contact post length. PCB footprint and clearance must be validated before implementation.

Q: What are the key differences between these two connectors?

A: The primary differences are product status (obsolete versus active), insulation material composition (PBT glass-filled versus polyester glass-filled), contact post finish (gold flash versus tin with thicker plating), and dimensional specifications. Electrical interface parameters remain identical.

Q: Is the substitute part RoHS compliant?

A: Yes, the TE Connectivity 8-534206-2 is RoHS compliant. The original 3M part does not specify RoHS status.

Q: What is the impact of the higher current rating on system design?

A: The substitute's 2A rating exceeds the original 1A specification. This provides design margin but does not alter the connector's electrical interface. Existing circuit designs rated for 1A operation remain valid with the substitute part.

Q: Are there packaging differences between these parts?

A: The 3M part packaging is not specified. The TE Connectivity substitute is supplied in tube packaging. Verify packaging requirements for your procurement and assembly processes.

Q: What should be verified before implementing the substitute?

A: Confirm PCB footprint compatibility, validate solder joint accessibility given the increased contact post length, and verify mechanical clearance with the reduced insulation height. Electrical performance requires no additional validation.
