Substitute Part Grouping Explanation

Substitution of the 53610-S40-4 is determined by strict equivalence across the following critical parameters:

Connector type (Header)
Contact type (Male Pin)
Position count (40 positions)
Row configuration (2 rows)
Mating pitch (0.100" / 2.54mm)
Row spacing (0.100" / 2.54mm)
Shrouding style (Shrouded - 4 Wall)
Mounting method (Through Hole)
Termination method (Solder)
Fastening mechanism (Latch Lock/Eject Hooks)
Contact shape (Square)
Contact material (Phosphor Bronze)
Insulation material (Thermoplastic)
Flammability rating (UL94 V-0)

The Amphenol ICC 53611-S40-4LF meets all these criteria and serves as the direct active equivalent. This part maintains identical mechanical and electrical interface specifications while offering improved compliance status.

Engineering Selection Recommendations

The 53611-S40-4LF is the direct active equivalent for the obsolete 53610-S40-4. Both parts maintain identical mechanical and electrical interface specifications across all critical parameters. The primary distinction is product status and compliance posture: the 53611-S40-4LF is actively manufactured and carries RoHS compliance certification, whereas the 53610-S40-4 is obsolete and RoHS non-compliant.

The contact finish on the post differs between the two parts: the 53610-S40-4 uses Tin-Lead with 150.0µin (3.81µm) thickness, while the 53611-S40-4LF uses Tin with 100.0µin (2.54µm) thickness. This change reflects modern lead-free manufacturing standards and does not affect functional compatibility in solder termination applications.

For new designs or ongoing procurement, the 53611-S40-4LF is the appropriate selection. For legacy system maintenance where the original 53610-S40-4 is specified, the 53611-S40-4LF provides direct functional substitution with improved compliance status.

Frequently Asked Questions (FAQ)

Q: Can the 53611-S40-4LF directly replace the 53610-S40-4 in existing assemblies?

A: Yes. The 53611-S40-4LF maintains identical mechanical and electrical interface specifications. All critical parameters including position count, pitch, row spacing, shrouding, mounting type, and termination method are equivalent. The parts are mechanically and electrically interchangeable.

Q: What is the significance of the contact finish difference between these parts?

A: The 53610-S40-4 uses Tin-Lead post finish (150.0µin), while the 53611-S40-4LF uses Tin post finish (100.0µin). This reflects the transition to lead-free manufacturing. Both finishes are compatible with standard solder termination processes and do not affect functional performance in board-to-cable/wire applications.

Q: Why is the 53610-S40-4 listed as obsolete?

A: The 53610-S40-4 has been superseded by the 53611-S40-4LF in the manufacturer's product line. The newer part offers improved compliance status, including RoHS compliance, while maintaining full functional equivalence.

Q: What packaging is available for the 53611-S40-4LF?

A: The 53611-S40-4LF is supplied in Tray packaging. Verify packaging requirements for your procurement process.

Q: Are there any electrical performance differences between these parts?

A: No. Both parts share identical contact material (Phosphor Bronze), contact geometry, mating contact finish (Gold or Gold, GXT™), and mating contact finish thickness (15.0µin). Electrical performance is equivalent.

Q: What is the moisture sensitivity level for these connectors?

A: Both the 53610-S40-4 and 53611-S40-4LF carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
