TE Connectivity AMP Connectors 87655-3 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 87655-3 is a rectangular connector header designed for through-hole, right-angle mounting applications. This connector features a 3-position configuration with 0.156" (3.96mm) pitch spacing and is part of the AMPMODU Mod I series. The part is classified as obsolete, necessitating identification of active equivalent alternatives for ongoing procurement and design requirements. Substitute parts must maintain electrical and mechanical compatibility while meeting current manufacturing and compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 87655-3 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Contact type (Male Pin)
• Number of positions (3)
• Pitch spacing (0.156" / 3.96mm)
• Current rating (5A)
• Operating temperature range (-65°C ~ 105°C)

Mechanical Compatibility Parameters:

• Mounting type (Through Hole, Right Angle)
• Contact length - mating (0.345" / 8.76mm)
• Contact length - post (0.150" / 3.81mm)
• Insulation height (0.250" / 6.35mm)
• Connector series (AMPMODU Mod I)

Compliance Parameters:

• Material flammability rating (UL94 V-0)
• Moisture sensitivity level (MSL 1)

The substitute part 5-87655-3 maintains all critical electrical and mechanical parameters while transitioning from an obsolete status to an active product status. The primary difference is the contact finish specification, which changes from Tin-Lead to Tin on both mating and post surfaces.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 5-87655-3 serves as the direct active equivalent to the obsolete 87655-3 connector. Selection of the substitute part is based on the following engineering criteria:

Product Status Transition: The 87655-3 is classified as obsolete, while the 5-87655-3 maintains active product status with current manufacturing support and availability.

Electrical and Mechanical Equivalence: All critical electrical parameters (contact type, position count, pitch spacing, current rating, operating temperature range) and mechanical parameters (mounting configuration, contact dimensions, insulation geometry) are identical between the main part and substitute.

Compliance Improvement: The substitute part 5-87655-3 achieves RoHS compliance, whereas the main part 87655-3 is RoHS non-compliant. Both parts maintain UL94 V-0 flammability rating and MSL 1 moisture sensitivity classification.

Contact Finish Specification: The primary technical difference is the contact finish material. The substitute transitions from Tin-Lead to Tin on both mating and post surfaces. Both finishes maintain the same thickness specification of 50.0µin (1.27µm) and are compatible with standard solder assembly processes.

Inventory and Procurement: The substitute part 5-87655-3 has 894 pieces in stock compared to 789 pieces of the obsolete part, supporting continuous supply chain requirements.

Frequently Asked Questions (FAQ)

Q: Can the 5-87655-3 be used as a direct replacement for the 87655-3 in existing designs?

A: Yes. The 5-87655-3 maintains identical electrical and mechanical specifications across all critical parameters including connector type, position count, pitch spacing, contact dimensions, current rating, and operating temperature range. The parts are mechanically and electrically interchangeable.

Q: What is the significance of the contact finish change from Tin-Lead to Tin?

A: The contact finish change reflects compliance with RoHS regulations. Tin-Lead finishes contain lead, which is restricted under RoHS directives. Tin finishes provide equivalent electrical performance and corrosion resistance while meeting environmental compliance requirements. Both finishes maintain the same thickness specification of 50.0µin (1.27µm).

Q: Are there any soldering process differences between the two parts?

A: No. Both the 87655-3 and 5-87655-3 use solder termination and are compatible with standard through-hole soldering processes. The transition from Tin-Lead to Tin finish does not require process modifications for standard lead-free solder assembly.

Q: What is the difference between the part numbers 87655-3 and 5-87655-3?

A: The part numbers differ due to manufacturing and compliance updates. The 5-87655-3 represents the current active production version of the connector, incorporating RoHS compliance and updated contact finish specifications. The base product number 87655 remains consistent across both variants.

Q: Are the mating and post contact lengths identical between the two parts?

A: Yes. Both parts specify identical contact dimensions: mating contact length of 0.345" (8.76mm) and post contact length of 0.150" (3.81mm). These dimensions ensure compatibility with existing mating connectors and PCB layouts.

Q: What is the current availability status for each part?

A: The 87655-3 is classified as obsolete with 789 pieces in stock. The 5-87655-3 is an active product with 894 pieces in stock, providing better long-term procurement support and supply chain continuity.

Q: Do both parts meet the same flammability and moisture sensitivity standards?

A: Yes. Both the 87655-3 and 5-87655-3 maintain UL94 V-0 material flammability rating and MSL 1 (Unlimited) moisture sensitivity level classification, ensuring equivalent performance in thermal and environmental conditions.
