Substitute Part Grouping Explanation

Substitution of the TE Connectivity 822516-1 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Type: PLCC socket
• Number of Positions: 44 (4 x 11) grid configuration
• Pitch - Mating: 0.050" (1.27mm)
• Pitch - Post: 0.050" (1.27mm)
• Mounting Type: Surface Mount
• Features: Closed Frame
• Termination: Solder
• Contact Finish - Mating: Tin or Tin-Lead
• Moisture Sensitivity Level: 1 (Unlimited)

Acceptable Variation Parameters:

• Contact Finish Thickness - Mating: 80.0µin to 160.0µin (2.03µm to 4.06µm)
• Contact Material - Mating: Phosphor Bronze or Copper Alloy
• Housing Material: Thermoplastic or Polybutylene Terephthalate (PBT), Glass Filled
• Operating Temperature: Specified range or unspecified
• Material Flammability Rating: UL94 V-0

All three substitute parts meet these criteria and are classified as active products, providing viable alternatives to the obsolete 822516-1.

Parameter Comparison

Engineering Selection Recommendations

3M 8444-21B1-RK-TP

The 3M 8444-21B1-RK-TP is an active PLCC-44 socket with ROHS3 compliance and UL94 V-0 flammability rating. This part features a polybutylene terephthalate housing with glass reinforcement, providing enhanced mechanical durability compared to standard thermoplastic. The operating temperature range of -40°C to 105°C accommodates standard industrial applications. Contact finish thickness of 160.0µin (4.06µm) provides extended contact life. This substitute is suitable for applications requiring higher reliability and environmental compliance.

Mercury United Electronics D00-044-490-001

The Mercury D00-044-490-001 is an active PLCC-44 socket with ROHS3 compliance and REACH unaffected status. This part utilizes tin-lead contact finish with 150.0µin (3.81µm) thickness. The D00 series designation indicates compatibility with legacy PLCC socket applications. This substitute is appropriate for designs requiring tin-lead contact finish specifications.

Adam Tech PLCC-44-AT-SMT

The Adam Tech PLCC-44-AT-SMT is an active PLCC-44 socket with ROHS3 compliance and UL94 V-0 flammability rating. This part features the lowest contact finish thickness at 80.0µin (2.03µm) and the widest operating temperature range of -55°C to 105°C. Documented contact resistance of 30mOhm and current rating of 1 A provide electrical performance specifications. This substitute is suitable for applications requiring extended temperature operation and cost-optimized contact specifications.

Frequently Asked Questions (FAQ)

Q: Can the 822516-1 be directly replaced with any of these substitute parts?

A: Yes. All three substitute parts meet the critical substitution parameters: 44-position PLCC configuration, 0.050" (1.27mm) pitch for both mating and post spacing, surface mount termination, closed frame design, and solder termination. All maintain UL94 V-0 flammability rating and MSL 1 moisture sensitivity level.

Q: What is the difference between tin and tin-lead contact finishes?

A: The TE Connectivity 822516-1 and Adam Tech PLCC-44-AT-SMT utilize tin contact finish. The Mercury D00-044-490-001 utilizes tin-lead contact finish. Both finishes are acceptable for PLCC socket applications; selection depends on specific design requirements and soldering process compatibility.

Q: How do contact finish thickness variations affect socket performance?

A: Contact finish thickness ranges from 80.0µin (Adam Tech) to 160.0µin (3M). Thicker finishes provide extended contact life and wear resistance. The TE Connectivity 822516-1 specifies 100.0µin (2.54µm), placing it in the mid-range. All specified thicknesses are within acceptable parameters for PLCC socket applications.

Q: Are all substitute parts RoHS compliant?

A: Yes. All three substitute parts are ROHS3 compliant. The original TE Connectivity 822516-1 lists RoHS status as not applicable due to its obsolete classification.

Q: What housing material differences exist among the substitutes?

A: The TE Connectivity 822516-1 and Adam Tech PLCC-44-AT-SMT use thermoplastic housing. The 3M 8444-21B1-RK-TP uses polybutylene terephthalate (PBT) with glass reinforcement, providing enhanced mechanical properties. Mercury D00-044-490-001 housing material is not specified. All materials meet UL94 V-0 flammability requirements.

Q: Which substitute part offers the widest operating temperature range?

A: The Adam Tech PLCC-44-AT-SMT specifies -55°C to 105°C operating temperature, the widest range among the substitutes. The 3M 8444-21B1-RK-TP specifies -40°C to 105°C. The TE Connectivity 822516-1 and Mercury D00-044-490-001 do not specify operating temperature ranges.

Q: Are there documented electrical specifications for these sockets?

A: The Adam Tech PLCC-44-AT-SMT provides documented specifications: 1 A current rating and 30mOhm contact resistance. The 3M 8444-21B1-RK-TP specifies 1 A current rating. The TE Connectivity 822516-1 and Mercury D00-044-490-001 do not provide contact resistance or current rating specifications.

Q: What is the significance of the closed frame feature?

A: All parts, including the original 822516-1 and all substitutes, feature closed frame design. This design provides mechanical support and alignment for PLCC integrated circuits during insertion and removal, ensuring reliable electrical contact and preventing pin damage.

Q: How does packaging affect part selection?

A: All substitute parts are supplied in tube packaging. The original TE Connectivity 822516-1 packaging is not specified. Tube packaging is standard for surface mount PLCC sockets and does not affect electrical or mechanical compatibility.
