Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1-822473-4 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Type: PLCC
• Number of Positions: 44 (4 x 11)
• Pitch - Mating: 0.050" (1.27mm)
• Pitch - Post: 0.100" (2.54mm)
• Contact Finish - Mating: Tin
• Contact Finish - Post: Tin
• Mounting Type: Through Hole
• Features: Closed Frame
• Termination: Solder
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

All three substitute parts meet these mandatory criteria. Variations in housing material composition, contact material specification (phosphor bronze versus copper alloy), operating temperature range, contact finish thickness, termination post length, and current rating represent acceptable engineering tolerances within the PLCC socket category and do not preclude functional substitution.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are classified as active products and maintain full compliance with ROHS3 and REACH regulatory requirements. The selection among A-CCS 044-Z-T, 8444-11B1-RK-TP, and PLCC-44-AT is based on availability, housing material composition, and contact material specifications.

A-CCS 044-Z-T (Assmann WSW Components): This substitute maintains phosphor bronze contact material consistent with the original 1-822473-4 specification. The part is available in high inventory (10,233 pieces) and features PBT housing material with specified operating temperature range of -40°C to 105°C and contact resistance of 15mOhm.

8444-11B1-RK-TP (3M Series 8400): This substitute employs copper alloy contact material and glass-filled PBT housing. The part is available in moderate inventory (5,655 pieces) with operating temperature range of -40°C to 105°C and 1 A current rating. Contact resistance is not specified.

PLCC-44-AT (Adam Tech): This substitute maintains phosphor bronze contact material and features glass-filled PBT housing. The part is available in lower inventory (2,809 pieces) and provides the widest operating temperature range of -55°C to 105°C with specified contact resistance of 30mOhm.

All three parts satisfy the mandatory electrical and mechanical compatibility requirements for direct substitution in applications previously utilizing the 1-822473-4.

Frequently Asked Questions (FAQ)

Q: What makes these parts suitable substitutes for the TE Connectivity 1-822473-4?

A: All substitute parts maintain identical PLCC socket configuration with 44 positions in a 4 x 11 grid, matching mating pitch of 0.050" (1.27mm), post pitch of 0.100" (2.54mm), tin contact finish, closed frame design, solder termination, through-hole mounting, UL94 V-0 flammability rating, ROHS3 compliance, and MSL 1 moisture sensitivity level. These parameters define functional equivalence for PLCC socket applications.

Q: Are there differences in contact material between the substitute options?

A: Yes. The A-CCS 044-Z-T and PLCC-44-AT utilize phosphor bronze contact material, matching the original 1-822473-4 specification. The 8444-11B1-RK-TP employs copper alloy contact material. Both material types are acceptable for PLCC socket applications and do not affect functional compatibility.

Q: What is the significance of housing material differences?

A: The original 1-822473-4 specifies thermoplastic housing. The substitute parts employ polybutylene terephthalate (PBT), with two options featuring glass-filled PBT. All housing materials maintain UL94 V-0 flammability rating and are suitable for through-hole solder mounting applications. Housing material composition does not affect electrical performance or mechanical fit.

Q: How do operating temperature ranges differ among the substitutes?

A: The A-CCS 044-Z-T and 8444-11B1-RK-TP specify -40°C to 105°C operating range. The PLCC-44-AT provides an extended lower temperature limit of -55°C to 105°C. Selection should be based on application temperature requirements. All three parts support standard industrial temperature ranges.

Q: What inventory levels are available for each substitute?

A: A-CCS 044-Z-T is available with 10,233 pieces in stock. 8444-11B1-RK-TP is available with 5,655 pieces in stock. PLCC-44-AT is available with 2,809 pieces in stock. Inventory levels should be considered for production planning and lead time requirements.

Q: Are all substitute parts RoHS and REACH compliant?

A: Yes. All three substitute parts are ROHS3 compliant and REACH unaffected, matching the regulatory status of the original 1-822473-4. This ensures compliance with current environmental and hazardous substance regulations.

Q: What is the difference in contact resistance specifications?

A: The A-CCS 044-Z-T specifies 15mOhm contact resistance. The PLCC-44-AT specifies 30mOhm contact resistance. The 8444-11B1-RK-TP does not provide contact resistance specification. Contact resistance values within this range are acceptable for standard PLCC socket applications and do not affect functional performance in typical circuit configurations.

Q: Can these parts be used interchangeably in existing PCB designs?

A: Yes. All substitute parts maintain identical through-hole mounting pitch and solder termination specifications, enabling direct PCB footprint compatibility with designs originally specified for the 1-822473-4.
