3M 2564-5002UB Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The 3M 2564-5002UB is a through-hole, right-angle rectangular connector header with 64 positions at 0.100" (2.54mm) pitch. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and production continuity. The connector features shrouded 4-wall construction with push-pull fastening, suitable for board-to-board or cable applications in industrial and commercial electronics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 2564-5002UB is determined by the following critical parameters:

• Connector configuration: 64-position, 2-row header at 0.100" (2.54mm) pitch
• Mounting and orientation: Through-hole, right-angle mounting
• Shrouding design: Shrouded 4-wall construction
• Contact system: Male pin contacts with gold mating finish
• Termination method: Solder termination
• Electrical performance: 1.75A current rating, operating range -55°C to 105°C minimum
• Mechanical compatibility: Contact length, insulation height, and overall form factor

The three substitute parts listed below meet these core requirements with minor variations in contact finish post material, insulation material composition, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

N2564-5002-RB (3M) is the primary substitute for the obsolete 2564-5002UB. Both parts share identical mechanical dimensions, electrical ratings, and material specifications. The N2564-5002-RB is currently in active production status with superior RoHS compliance and maintains the same 3M manufacturing ecosystem, reducing qualification risk and supply chain complexity.

09185645323 (HARTING) provides an alternative from an established connector manufacturer. This part maintains core electrical and mechanical compatibility with slightly increased insulation height (0.366" vs. 0.338") and extended operating temperature range to 125°C. The fastening mechanism differs (latch holder versus push-pull), which may require mechanical interface evaluation. HARTING components are ROHS3 compliant and widely available.

TSS-132-04-F-D-RA (Samtec Inc.) offers compatibility through the Flex Stack TSS series. This connector features increased contact post length (0.130" vs. 0.112") and phosphor bronze contact material instead of copper alloy. The extended operating temperature to 125°C and ROHS3 compliance support modern design requirements. Mechanical interface differences require assessment before implementation.

For designs requiring strict form-factor compatibility and minimal qualification effort, N2564-5002-RB is the recommended path. For applications requiring extended temperature performance or alternative supplier qualification, HARTING 09185645323 or Samtec TSS-132-04-F-D-RA are viable options pending mechanical interface validation.

Frequently Asked Questions (FAQ)

Q: Can the N2564-5002-RB directly replace the 2564-5002UB without PCB modification?

A: Yes. The N2564-5002-RB maintains identical pitch (0.100"), position count (64), row configuration (2), mounting type (through-hole right-angle), and contact dimensions. No PCB layout changes are required.

Q: What is the primary difference between the 2564-5002UB and N2564-5002-RB?

A: The N2564-5002-RB uses tin-only post finish instead of tin-lead and is RoHS compliant. The mating contact finish (gold) and electrical performance remain identical.

Q: Why do the HARTING and Samtec alternatives have different insulation heights?

A: Insulation height variation reflects different connector series designs. HARTING 09185645323 (0.366") and Samtec TSS-132-04-F-D-RA (0.365") use different insulation material compositions and manufacturing processes. These differences are within acceptable mechanical tolerance for standard board-to-board applications but require clearance verification in space-constrained designs.

Q: Does the fastening type difference between push-pull and latch holder affect compatibility?

A: Fastening type affects mating force and mechanical retention but not electrical compatibility. The HARTING 09185645323 uses latch holder fastening versus push-pull on the original part. Mechanical interface compatibility must be evaluated based on mating connector design and application requirements.

Q: Are all substitute parts RoHS compliant?

A: The original 2564-5002UB is RoHS non-compliant. N2564-5002-RB is RoHS compliant. HARTING 09185645323 and Samtec TSS-132-04-F-D-RA are both ROHS3 compliant, meeting current regulatory requirements.

Q: What is the inventory status for each part?

A: 2564-5002UB: 1127 pcs (obsolete status). N2564-5002-RB: 2386 pcs (active). 09185645323: 724 pcs (active). TSS-132-04-F-D-RA: 955 pcs (active).

Q: Can I use these connectors in applications exceeding 105°C?

A: The original 2564-5002UB is rated to 105°C. HARTING 09185645323 and Samtec TSS-132-04-F-D-RA both support -55°C to 125°C operation. N2564-5002-RB maintains the 105°C upper limit. Application temperature requirements determine which substitute is appropriate.
