TE Connectivity AMP Connectors 536255-1 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 536255-1 is a 40 Position Receptacle Connector with 0.050" (1.27mm) pitch, designed for board-to-board applications using through-hole solder termination. This connector features a push-pull fastening mechanism, gold-plated mating contacts, and tin-lead post finish. The part is classified as obsolete, necessitating identification of active equivalent alternatives to support ongoing procurement and system maintenance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for rectangular connectors is determined by strict equivalence across electrical and mechanical parameters. The following criteria establish direct substitutability:

Critical Matching Parameters:

• Connector type (Receptacle)
• Contact type (Female Socket)
• Number of positions (40)
• Pitch - mating (0.050" / 1.27mm)
• Number of rows (2)
• Row spacing - mating (0.100" / 2.54mm)
• Mounting type (Through Hole)
• Termination method (Solder)
• Fastening type (Push-Pull)
• Contact finish - mating (Gold)
• Operating temperature range (-65°C ~ 125°C)
• Voltage rating (30VAC)
• Series designation (Micro-Strip)
• Style (Board to Board)

Parts meeting all these parameters are classified as direct equivalents and may be substituted without design modification or re-qualification.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity AMP Connectors 5536255-1 is a direct functional equivalent to the obsolete 536255-1 model. Both connectors share identical electrical and mechanical specifications across all critical parameters including connector type, position count, pitch, row configuration, mounting method, and operating characteristics.

Key Distinctions:

The 5536255-1 is classified as an active product with ROHS3 compliance status, whereas the 536255-1 is obsolete and RoHS non-compliant. The contact post finish differs between the two parts: the main part features tin-lead plating while the substitute uses tin plating. This variation in post finish does not affect electrical performance or mechanical compatibility, as both finishes meet the same solder joint reliability requirements for through-hole termination.

For new designs and ongoing procurement, the 5536255-1 is the appropriate selection due to its active product status and regulatory compliance. For legacy system maintenance where the original 536255-1 is specified, the 5536255-1 provides direct substitution without circuit redesign or board layout modification.

Frequently Asked Questions (FAQ)

Q: Can the 5536255-1 be used as a direct replacement for the 536255-1 in existing assemblies?

A: Yes. The 5536255-1 is a direct functional equivalent with identical electrical and mechanical specifications. No design changes, board layout modifications, or re-qualification are required for substitution in existing applications.

Q: What is the significance of the contact post finish difference (tin-lead vs. tin)?

A: Both tin-lead and tin post finishes are compatible with standard solder reflow and wave soldering processes. The tin finish on the 5536255-1 meets equivalent solder joint reliability standards. This variation does not impact electrical performance or mechanical engagement.

Q: Why is the 536255-1 classified as obsolete?

A: The 536255-1 has been superseded by the 5536255-1, which maintains full functional equivalence while offering active product status and improved regulatory compliance (ROHS3).

Q: Are there any compatibility concerns with mating connectors?

A: No. Both the 536255-1 and 5536255-1 are receptacle connectors designed for board-to-board applications with identical pitch (0.050"), row spacing (0.100"), and mechanical dimensions. They are compatible with the same plug connectors and mating interfaces.

Q: What is the inventory status for the substitute part?

A: The 5536255-1 has 1133 pieces of new original stock currently available, compared to 1154 pieces for the obsolete 536255-1.

Q: Are there any regulatory or compliance differences between the two parts?

A: The 5536255-1 is ROHS3 compliant, while the 536255-1 is RoHS non-compliant. Both parts share the same ECCN (EAR99) and HTSUS classification. For applications subject to RoHS regulations, the 5536255-1 is the required selection.
