TE Connectivity 1-535542-0 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 1-535542-0 is a 20-position rectangular receptacle connector from the AMPMODU Mod IV series, designed for board-to-board or cable applications with 0.100" (2.54mm) pitch through-hole mounting. This connector features gold-plated mating contacts and tin-lead plated posts for solder termination with push-pull fastening. The part is currently active in production with 770 units in stock. Equivalent and substitute parts are identified to provide procurement flexibility, support supply chain continuity, and accommodate specific compliance or material finish requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of rectangular connectors within the AMPMODU Mod IV series is determined by strict equivalence across the following critical parameters:

Mechanical Compatibility:

• Connector type (Receptacle, Bottom or Top Entry)
• Number of positions (20)
• Pitch spacing (0.100" / 2.54mm)
• Number of rows (2)
• Row spacing (0.100" / 2.54mm)
• Mounting type (Through Hole)
• Insulation height (0.265" / 6.73mm)

Electrical Compatibility:

• Contact type (Female Socket)
• Current rating (2A)
• Operating temperature range (-65°C ~ 125°C)
• Contact material (Phosphor Bronze)
• Contact shape (Square)

Termination Compatibility:

• Termination method (Solder)
• Fastening type (Push-Pull)
• Contact length - post (0.130" / 3.30mm)
• Contact finish thickness - post (150.0µin / 3.81µm)

The substitute part 6-535542-0 maintains full equivalence across all mechanical, electrical, and termination parameters. Differences exist only in contact finish post material (Tin versus Tin-Lead), material flammability rating (UL94 V-0 versus unspecified), and RoHS compliance status (RoHS Compliant versus Not applicable).

Parameter Comparison

Engineering Selection Recommendations

Part 1-535542-0 (Main Part):

• Select when tin-lead post finish is specified in design documentation
• Use when RoHS compliance is not a requirement
• Suitable for applications where material flammability rating is not contractually mandated

Part 6-535542-0 (Substitute):

• Select for designs requiring RoHS compliance
• Use when UL94 V-0 flammability rating is specified
• Preferred when tin post finish (lead-free) is required
• Recommended for new designs due to active production status and higher inventory availability

Both parts are active products from TE Connectivity and maintain identical mechanical, electrical, and thermal specifications. The primary differentiators are post contact finish composition, flammability certification, and regulatory compliance status. Selection between these parts depends on specific design requirements and regulatory constraints rather than functional performance.

Frequently Asked Questions (FAQ)

Q: Can 6-535542-0 be used as a direct replacement for 1-535542-0 in existing designs?

A: Yes. Both parts are mechanically and electrically identical across all critical parameters including connector type, position count, pitch, mounting method, current rating, and operating temperature. The substitute maintains full compatibility with mating connectors and PCB layouts designed for the original part.

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

A: The main part (1-535542-0) uses tin-lead plating on the solder posts, while the substitute (6-535542-0) uses pure tin plating. Both finishes provide equivalent electrical performance and solder joint reliability at the specified 2A current rating. The tin finish in the substitute eliminates lead content, supporting RoHS compliance requirements.

Q: Does the UL94 V-0 rating on 6-535542-0 affect electrical performance?

A: No. The UL94 V-0 flammability rating applies to the insulation material (polyester, glass-filled) and indicates superior flame resistance. This certification does not alter electrical characteristics, current capacity, or operating temperature range. Both parts use identical insulation material composition.

Q: Are these connectors compatible with AMPMODU Mod IV plugs?

A: Yes. Both receptacle parts are designed for the AMPMODU Mod IV series and mate with standard Mod IV plug connectors. The identical pitch (0.100"), row spacing (0.100"), and mechanical dimensions ensure full compatibility.

Q: What is the significance of the different part number prefixes (1- versus 6-)?

A: The prefix indicates different manufacturing or distribution batches within TE Connectivity's product line. Both parts share the same base product number (535542) and are functionally equivalent. The prefix does not affect performance or compatibility.

Q: Which part should be selected for new PCB designs?

A: Part 6-535542-0 is recommended for new designs due to its RoHS compliance status, documented UL94 V-0 flammability rating, and higher current inventory availability (1128 units versus 770 units). This part supports modern regulatory requirements and provides better supply chain continuity.

Q: Can these parts be mixed in the same assembly?

A: Yes. Both parts are mechanically and electrically interchangeable. However, for consistency and traceability, it is standard practice to use a single part number throughout an assembly unless design documentation explicitly permits substitution.

Q: What is the Moisture Sensitivity Level (MSL) rating?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity. These connectors do not require special handling, storage, or baking procedures prior to soldering and can be stored under standard warehouse conditions indefinitely.
