TE Connectivity 5646442-9 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 5646442-9 is a 176-position receptacle connector with female sockets, designed for backplane applications. This connector features a 2.00mm pitch, board edge mounting with through-hole termination, and right-angle orientation. The part is actively manufactured and stocked, with RoHS compliance and unlimited moisture sensitivity rating. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design flexibility permits component interchange based on equivalent electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 5646442-9 are identified based on electrical and mechanical parameter equivalence. The substitution criteria include:

Critical Matching Parameters:

• Connector type: Receptacle, Female Sockets
• Number of positions: 176
• Pitch: 0.079" (2.00mm)
• Number of rows: 8
• Mounting type: Board Edge, Through Hole, Right Angle
• Termination method: Press-Fit
• Contact finish: Gold with 30.0µin thickness
• Current rating: 1.5 A
• Voltage rating: 750Vrms
• Operating temperature range: -55°C to 125°C
• Connector style: D 22

Parts meeting all these parameters are classified as direct substitutes. Packaging format and series designation do not affect electrical or mechanical compatibility for connector interchange applications.

Parameter Comparison

Engineering Selection Recommendations

Both the TE Connectivity 5646442-9 and Amphenol ICC HM2R87PA8100N9LF are active products with equivalent electrical and mechanical specifications. Selection between these parts is based on availability, packaging format, and regulatory compliance status.

TE Connectivity 5646442-9 is supplied in tube packaging with RoHS compliance certification. Current inventory is 989 pieces.

Amphenol ICC HM2R87PA8100N9LF is supplied in tray packaging with ROHS3 compliance certification and includes a board guide feature. Current inventory is 799 pieces.

Both connectors meet identical electrical requirements, temperature specifications, and contact finish standards. The choice between these parts depends on procurement requirements, packaging preferences, and specific compliance documentation needed for the application. Both parts carry REACH Unaffected and EAR99 export classification status.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol ICC HM2R87PA8100N9LF directly replace the TE Connectivity 5646442-9?

A: Yes. Both connectors share identical electrical ratings (1.5 A, 750Vrms), mechanical configuration (176 positions, 2.00mm pitch, 8 rows, right-angle board edge mounting), and termination method (press-fit). All contact specifications and operating temperature ranges are equivalent.

Q: What is the difference between RoHS and ROHS3 compliance?

A: Both certifications indicate compliance with Restriction of Hazardous Substances regulations. ROHS3 represents the current version of the directive. Both parts meet the same hazardous substance restrictions and are suitable for applications requiring RoHS compliance.

Q: Does the board guide feature on the Amphenol ICC part affect compatibility?

A: The board guide is an additional feature that does not affect electrical or mechanical compatibility. It provides enhanced mechanical alignment during assembly. The presence of this feature does not prevent substitution.

Q: What is the significance of packaging format (tube versus tray)?

A: Packaging format affects handling, storage, and automated assembly processes but does not impact connector performance or electrical characteristics. Selection between tube and tray packaging depends on manufacturing workflow and inventory management requirements.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both connectors operate across the identical temperature range of -55°C to 125°C with equivalent performance specifications.

Q: What does Moisture Sensitivity Level 1 (Unlimited) mean?

A: MSL 1 indicates the connector has unlimited shelf life and requires no special moisture control during storage or handling. Both parts carry this rating.
