Key Parameters

Substitute Part Grouping Explanation

The substitute part 5-535542-2 is functionally equivalent to the main part 535542-2 based on the following critical parameters that determine substitutability:

Electrical and Mechanical Compatibility:

• Identical number of positions (4)
• Identical pitch spacing (0.100" / 2.54mm)
• Identical row configuration (2 rows with 0.100" spacing)
• Identical mounting type (Through Hole)
• Identical contact type (Female Socket)
• Identical current rating (2A)
• Identical operating temperature range (-65°C ~ 125°C)
• Identical mating contact finish (Gold at 30.0µin / 0.76µm)
• Identical insulation material (Polyester, Glass Filled)
• Identical contact material (Phosphor Bronze)

Differences in Compliance and Post Finish:

• Contact Finish - Post: Tin-Lead (535542-2) versus Tin (5-535542-2)
• Material Flammability Rating: Not specified (535542-2) versus UL94 V-0 (5-535542-2)
• RoHS Status: Non-compliant (535542-2) versus Compliant (5-535542-2)

These differences do not affect the core electrical or mechanical interface compatibility. The substitute part provides enhanced compliance certifications and improved flammability characteristics while maintaining identical connector geometry and performance specifications.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection Criteria:

The 535542-2 and 5-535542-2 are direct functional equivalents for applications requiring a 4-position, 0.100" pitch through-hole receptacle connector with 2A current capacity and -65°C to 125°C operating range.

Compliance-Based Selection:

Select 5-535542-2 for applications subject to RoHS compliance requirements or where UL94 V-0 flammability certification is mandated. This part meets both RoHS compliance and UL94 V-0 material flammability standards.

Select 535542-2 for applications without RoHS compliance requirements and where tin-lead post finish is acceptable or preferred.

Post Finish Consideration:

The 535542-2 features tin-lead post finish, while 5-535542-2 features tin post finish. Both finishes provide equivalent solder joint reliability at the specified current and temperature ratings. The tin post finish in 5-535542-2 aligns with lead-free soldering practices.

Inventory and Availability:

The 5-535542-2 substitute part maintains higher inventory levels (2426 units) compared to the main part (1114 units), supporting consistent supply chain availability.

Frequently Asked Questions (FAQ)

Q: Are the 535542-2 and 5-535542-2 interchangeable in PCB assembly?

A: Yes. Both parts are mechanically and electrically identical in terms of connector geometry, contact configuration, pitch spacing, and electrical performance. They mount identically to PCBs and mate with the same plug connectors. The differences are limited to post finish material and compliance certifications.

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

A: The 535542-2 uses tin-lead plating on the solder posts, while 5-535542-2 uses tin plating. Both finishes provide equivalent electrical conductivity and solder joint strength at the specified 2A current rating and -65°C to 125°C operating temperature. Tin finish is preferred in lead-free soldering environments.

Q: Which part should I select for RoHS-compliant applications?

A: Select 5-535542-2, which carries RoHS Compliant status. The 535542-2 is RoHS non-compliant.

Q: Does the UL94 V-0 rating on 5-535542-2 affect connector performance?

A: 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 or mechanical performance but is required for applications in regulated industries or safety-critical systems.

Q: Can I use 535542-2 in applications where 5-535542-2 is specified?

A: Substitution is possible only if the application does not require RoHS compliance or UL94 V-0 certification. Verify compliance requirements with your design specification before substitution.

Q: Are there any thermal or current rating differences between these parts?

A: No. Both parts are rated for 2A current and operate across -65°C to 125°C. Thermal and electrical performance are identical.

Q: What is the pitch spacing of these connectors?

A: Both connectors feature 0.100" (2.54mm) pitch spacing for both mating and row spacing, supporting standard 0.1-inch grid PCB layouts.

Q: Are these connectors suitable for board-to-board and cable applications?

A: Yes. Both parts are classified as Board to Board or Cable style connectors with bottom or top entry configuration, supporting flexible application requirements.
